Four New Species of Megathymus (Lepidoptera, 
Rhopalocera, Megathymidae) 

By DON B. STALLINGS and J. R. TURNER 

Megathymus alliae, new species 

FEMALE : Upper surface of primaries. Dull black with the 
base overscaled with dull yellow-brown. Spots 1 (cell spot), 
2, 3, 4 (subapical spots), 5, 6 (submarginal spots), 7, 8 and 9 
(discal band) bright yellow-brown. Spot 7, 9 mm. wide ; spot 
8, 8 mm. wide; spot 9, 7 mm. wide. The dull yellow-brown 
overscaling extends about halfway in the costal area, and about 
three-fourths the way towards the outer angle. Veins narrowly 
edged with dull black. Fringes dull yellow-brown with vein 
tips smoky. 

Upper surface of secondaries. Dull black, basal third cov- 
ered with dull yellow brown hairs, with further dull yellow 
brown overscaling in the anal area. The discal band is com- 
posed of 5 bright yellow-brown spots, separated by narrow dull 
black lines along the veins. The discal band is about the same 
width as the dull black marginal area. Fringes dull yellow- 
brown with vein tips faintly smoky. 

Under surface of primaries. Dull black with the apex heavily 
overscaled with dull yellow-brown. All the spots reappear with 
spots 2, 3, and 4 lighter in color. 

Under surface of secondaries. Dull black heavily overscaled 
with dull yellow-brown. The discal band appears only as a 
series (reduced in size) of lighter spots in the overscaling. 
There are two faint spots below the costal area.

the collection of the authors. Paratypes of both sexes will be 
placed in the following collections : H. A. Freeman, C. L. 
Remington, U. S. Nat. Museum, American Mus. of Nat. His- 
tory, Los Angeles County Museum. 

Food plant : Agave utahensis Engelmann. 

It will be interesting to learn whether M. alliae uses Agave 
kaibabensis McKelvey (a closely allied species of Agave utahen- 
sis which occurs on the north rim of Grand Canyon) as a food 
plant. 

The females select medium sized plants for oviposition. The 
trap door, which is paper white, is nearly always (we have seen 
one exception) on the under side of the leaf. 

It is rather difficult to select the nearest relative of M. alliae 
from which to distinguish it, for M. alliae does not fit in with 
any of the now known groups of species of Megathymus. M. 
alliae is the largest known species in the U. S. A. that feeds on 
the Agave. We will distinguish it from M. baueri Stallings & 
Turner as the two species are similar in some respects and occur 
rather close to each other. 

First, M. alliae is distinguished from M. baueri by its huge 
size. The ground-color of the upper surface of M. alliae is 
dull black while in M. baueri it is deep black. The under sur- 
face of M. alliae has much heavier overscaling and this over- 
scaling has much more yellow in it than does M. baueri. In the 
female the deep black ground color of M. baueri on its upper 
surface is much more extensive than in M. alliae. 

The valva of the genitalia of the male M. alliae is characterized 
by having the projection at the apex uniformly narrow. In 
M. baueri and allied species this projection is tapered. In M. 
alliae the uncus seen in lateral view abruptly turns down at 
its apex while in M. baueri and related species the apex curves 
down, evenly. In the female of M. alliae the center portion of 
the genital plate is built more complex than M. baueri and 
allied species. 

This species is named in honor of the mother-in-law and 
mother of the authors, Mrs. R. C. (Allie) Turner, who has 
aided materially in our work on the genus Megathymus and 
who collected the first pupa of this new species. 



Ixviii] ENTOMOLOGICAL NEWS 5 

The next three species to be described all belong to the 
Megathymus neumoegeni Edwards complex. We will first 
describe all three, then consider them together with M. neu- 
mocycni and with M. chisosensis and M. nicalpinei recently 
described by H. A. Freeman, both of which belong to this group. 

Megathymus judithae, new species 

FEMALE : Upper surface of primaries. Light orange with a 
black border along the outer edge of the wing approximately 
4 mm. wide. Spots 1 (cell spot), 2, 3, 4 (subapical spots), 5, 6 
(submarginal spots), 7, 8, and 9 (discal band) are all fused 
together with the light orange in the basal area. There is an 
irregular black spot between the cell and subapical area. There 
is a black line of color in the costal area towards the base. 
About equidistant between the base of the wing and the outer 
angle there is an irregular square black spot (actually two spots 
fused together) that is 4 mm. wide. Above this fused spot is 
a small black spot 1.5 mm. wide. Fringes yellow with vein 
tips black. 

Upper surface of secondaries. Light orange with marginal 
black border. There is a band of black, heavily overscaled with 
light orange inward from the discal area. This band becomes 
weaker in color and narrower as it approaches the anal area. 
Fringes yellow with vein tips black. 

Under surface of primaries. Dull brown-black with apex 
overscaled with white giving it a gray appearance. Spots 1, 2, 
3, 4, 5, 6, 7, 8, and 9 appear on this surface as spots. All spots 
light orange in color except spots 2, 3, and 4 which are white. 

Under surface of secondaries. Dull brown-black overscaled 
with white giving a gray appearance. At the base of the wing 
there are a few white hairs mixed with light orange hairs. In 
the anal area there are a few light orange scales mixed with 
the white scales. The discal band is indicated by heavier white 
overscaling. There is a round white spot in the costal area with 
a smaller white spot below it. 

Abdomen, orange above, gray- white beneath. Thorax, yellow- 
gray above, white beneath. Palpi, dull white. Antennae, white 
ringed with black, base of antennae white, remainder black.

MALE: Upper surface of primaries. Black with the base 
overscaled with light orange. Spots 1, 2, 3, 4, 5, 6, 7, 8, and 9 
light orange, spot 9 narrower than spots 7 and 8. Fringes 
yellow with vein tips black. 

Upper surface of secondaries. Light orange with a marginal 
black border. All very similar to female. Fringes yellow with 
vein tips black. 

Under surface of primaries. Dull black with apex overscaled 
with white. Spots reappear as above, except that spots 2, 3, 
and 4 are white. 

Under surface of secondaries. Similar to female with discal 
band not so well denned. 

Abdomen, thorax, palpi, and antennae same as female. 

Expanse of forewing of female varies from 25 to 32 mm. ; 
average 30 mm. Wing measurements of holotype : Forewing, 
apex to base 32 mm., apex to outer angle 18 mm., outer angle 
to base 22 mm. ; hindwing, base to end of vein Cu x 22 mm. 

Expanse of forewing of male varies from 26 to 29 mm. ; 
average 28 mm. Wing measurements of allotype : Forewing, 
apex to base 28 mm., apex to outer angle 16 mm., outer angle 
to base 20 mm. ; hindwing, base to end of vein Cn l 20 mm. 

Described from 24 males and 23 females collected in the 
Hueco Mts., near Hueco, Texas, elevation 5300 feet. All ex- 
larvae or ex-pupae emerging from Sept. 10 to Sept. 30 during 
1953 and 1954. Collected by Dr. and Mrs. R. C. Turner, Judith, 
Gayle, Beulah and J. R. Turner, Dee, Jack, Viola and Don B. 
Stallings. 

Holotype, female, Sept. 21, 1953, Hueco Mts., Hueco, TEXAS, 
el. 5300 ft. (Turner) ; allotype, male, Sept. 20, 1954, Hueco 
Mts., Hueco, Texas, el. 5300 ft. (Stallings & Turner) are in 
the collection of the authors. Paratypes of both sexes will be 
placed in the following collections : H. A. Freeman, C. L. 
Remington, U. S. Nat. Museum, American Mus. of Nat. 
History. 

Food plant : Agave parryi Engelmann. It is well to note 
here that the name Agave parryi is applied loosely. Agave 
parryi in the Hueco Mts. of Texas is not the same thing as 
Agave parryi in the Guadeloupe Mts. of Texas and N. Mex.

This species is named in honor of Judith Turner, the daughter 
of J. R. Turner, who was present when the species was dis- 
covered and helped collect the type series. 

The females select medium sized plants for oviposition. The 
trap door which is medium brown in color is usually on the 
upper side of the leaf. The length of the pupal case is 3.3 times 
the diameter of the case. 

Megathymus carlsbadensis, new species 

FEMALE : Upper surface of primaries. Bright yellow-orange 
with a black border along the outer edge of the wing, approxi- 
mately 5 mm. wide. Spots 1 (cell spot), 2, 3, 4 (subapical 
spots), 5, 6 (submarginal spots), 7, 8, and 9 (discal band) are 
all fused together with the bright yellow orange in the basal 
area. There is an irregular black spot between the cell and sub- 
apical area. There is a thick black line of color in the costal 
area towards the base. About equidistant between the base of 
the wing and the outer angle there is an irregular black spot 
(actually two spots fused together). The bottom half of this 
fused spot is 4 mm. wide, the top half 5 mm. wide. Above 
this fused spot there is a small triangular spot (with the apex 
of the triangle pointed towards the base of the wing) that is 
2.5 mm. wide. Fringes checkered yellow and black. 

Upper surface of secondaries. Bright yellow-orange with 
marginal black border. There is a band of black overscaled 
with bright yellow-orange inward from the discal area. Fringes 
checkered yellow and black. 

Under surface of primaries. Brown-black with apex over- 
scaled with white giving it a gray appearance. Spots 1, 2, 3, 4, 
5, 6, 7, 8, and 9 appear on this surface as spots, slightly lighter 
in color than the upper surface, except spots 2, 3, and 4 which 
are white, and spots 5 and 6 which are pale yellow-orange. 

Under surface of secondaries. Brown black overscaled with 
white giving a gray appearance. At the base of the wing there 
are a few white hairs, sometimes with a few yellow hairs mixed 
in. In the anal area there is a strip with little white overscaling 
but usually has a few light orange scales. The discal band is 



Ixviii] ENTOMOLOGICAL NEWS 

faintly indicated by slightly more white overscaling. There is 
a distinct round white spot in the costal area with a smaller 
(and fainter) white spot below it. 

Abdomen, bright yellow-orange above, gray-white beneath. 
Thorax orange-gray above, gray white beneath. Palpi, gray- 
white. Antennae, white ringed with black, base of antennae 
white, remainder black.

overscaled with reddish orange. Spots 1, 2, 3, 4, 5, 6, 7, 8, and 
9 reddish orange. Spots 7, 8, and 9 all about the same size 
(3 mm.). Fringes yellow with vein tips black. 

Upper surface of secondaries. Reddish orange with a mar- 
ginal black border. All very similar to the female. Fringes

Yucca Canyon, el. 5470 ft. (Turner) ; allotype, male, Sept. 21, 
1953, same data and collector, are in the collection of the au- 
thors. Paratypes of both sexes will be placed in the following 
collections: H. A. Freeman, C. L. Remington, U. S. National 
Museum, American Mus. of Nat. History. 

Food plant : Agave parryi Engelmann. There are three spe- 
cies of Agave plants in the Guadeloupe Mts. : A. parryi, A. lechu- 
guilla Torrey and what we believe to be A. chisosensis Mueller 
(Mrs. Stallings and some other members of the family feel that 
the last named may in fact be a hybrid between the first two 
named). 

In this area Agave lechuguilla always produced Megathymus 
mariae and nothing else. In the area around Nickle, Texas 
(Parker Ranch) we found A. parryi and A. chisosensis in about 
equal numbers, and in this area Megathymus carlsbadensis laid 
eggs on both species of plants in about equal numbers. In 
August of 1954 we made a rather careful survey of the situa- 
tion. At that time nearly 80% of the A. parryi plants that had 
had eggs of M. Carlsbadensis laid on them, still had live larvae 
in the leaves (these were plants that showed that the larvae 
had hatched from the egg and entered the leaves). On the 
other hand only 20% of the A. chisosensis plants at that time 
(which had had larvae hatch and enter the leaves) had live 
larvae. We were successful in securing 6 butterflies from A. 
chisosensis, but these were not included in the type series of 
M. carlsbadensis. The first specimen that hatched from A. 
chisosensis (a female) was distinctly different from M. carlsba- 
densis; the other five specimens appear identical to M. carls- 
badensis. H. A. Freeman and C. L. Remington, who have both 
examined the above mentioned female, are of the opinion that 
this female may be a distinct species. More specimens will have 
to be secured before a final determination can be made. In the 
meantime, we are inclined to consider the five other specimens 
that we secured from A. chisosensis as belonging to M. carls- 
badensis, although we do not consider A. chisosensis the normal 
food plant. Population pressure could explain the use of this 
plant as food.

This species is named in honor of Miss Florence Draper, who 
gave the first named author, a great deal of encouragement, 
when a small boy, to continue his work in the field of the 
Lepidoptera. 

For a number of years both H. A. Freeman and our group have 
known that a species of Megathymus occurred in the Davis Mts. 
None of us had been able to find the larvae. In 1954 Freeman 
was supposed to join us in a joint effort to work out the prob- 
lem, but at the last minute was unable to join us. Plants of 
all sizes were plentiful in the area that we hunted (this species 
of Agave grows considerably bigger than A. parryi), but the 
first day that we hunted we found only one larva in a medium 
sized plant and it was parasitized. The second day as we con- 
tinued to hunt without a sign of a larva Jack Stallings sug- 
gested that we check some of the tiny juvenile plants that are 
so small that they do not reach the height of the short grass in 
the area. Improbable as this seemed we started checking the 
tiny plants. The larvae were there. All of the type series were 
collected from these tiny plants. This distinct difference in the 
size of the food plant selected by the female upon which to ovi- 
posit is, in our opinion, a significant difference between this 
species and other species of this species group which use much 
larger (and older) plants on which to lay eggs. Later this same 
year, while on Mingus Mt. in Arizona hunting for larvae of 
M. neumoegeni, we found that M. neumoegeni uses the tiny 
juvenile plant for the food plant. 

The trap door, which is amber in color, is usually on the 
upper side of the leaf. The length of the pupa case is 4.35 
times the diameter of the case, and this difference in propor- 
tions from the two previously described species we also con- 
sider significant. 

We are well aware that in describing allopatric species such 
as these that it may be that we are dealing with subspecies of 
one polytypic species. If we were separating these species on 
morphological characters alone we would be more inclined to 
treat them as subspecies. Another difficulty with treating them 
as subspecies is that with six distinct forms before us no cline

seems to appear. Freeman has already described two species 
(chisosensis and mcalpinei} in this group and has examined the 
type series of the three here described and agrees with us that 
all are species. 

While all six species appear somewhat alike it is rather sim- 
ple to separate them by constant differences. One of the key 
differences in the females is the black spots on the upper surface 
of the forewing located between the base of the wing and the 
outer angle, usually two or three spots, one above the other. 
If the spot is about round we call it a dot and if elongated a 
dash, if one of the spots is absent we call that a blank. Listing 
the spots from the bottom to the top of the wing, we then have : 

neumoegeni: dash-dash-dot 
chisosensis : dot-dash-dot 
mcalpinei: dot-dash-dot 
judithae : dash-dash-dot 
carlsbadensis: dash-dash-dot 
florenceae: dash-dash-blank 

This key separates florenceae into a group by itself, cliisosensis 
and mcalpinei into a second group and judithae, carlsbadensis 
and neumoegeni into a third group. Neurnoegcni (in both 
sexes) separates from all the others by its slightly smaller size 
and the darker ground color (less white overscaling) of the 
undersurfaces of both wings. Judithae (in both sexes) sep- 
arates from the others by its lighter orange color. Cliisosensis 
(in both sexes) separates from the others by the extreme amount 
of black on the upper surfaces of both wings. The "dot" on the 
female neumoegeni is much smaller than on either judithae or 
carlsbadensis. 

In the males of the six species (except chisosensis) on the 
upper surface of the forewings there is a large irregular black 
spot near the base of the wings. This spot is roundish in neu- 
moegeni, judithae and carlsbadensis, and is rectangular (longer 
with the body, than wide) in florenceae and mcalpinei. In 
florenceae the bright orange spot inward from spot 8 always 
separates it from mcalpinei. 



Ixviii] ENTOMOLOGICAL NEWS 17 

All six species are found in isolated desert mountains ; the 
habitat, however, differs. Neumoegeni, chisosensis and floren- 
ceae are found in open woods while carlsbadensis, judithac and 
nicalpinei, particularly the first two, are found in open country. 
The last three named lay eggs on medium to large plants ; 
neumoegeni and florenceae lay their eggs on tiny juvenile plants. 
From the few larvae and pupae collected it appears that chiso- 
sensis lays its eggs on medium to large plants. 

The genitalia of the six species are different ; however, the 
female genitalia seem to break into two groups : nicalpinei, 
carlsbadensis and florenceae in one group and neumoegeni, 
judithae and chisosensis in the other. The male genitalia break 
into three groups : neumoegeni and judithae; florenceae and 
nicalpinei; chisosensis and carlsbadensis. 



A Character Useful in Separating Cafius (sg. Bryo- 

nomus Csy.) seminitens Horn and canescens 

Makl. (Coleoptera: Staphylinidae) 

By RUDOLF DVORAK, Praha, Czechoslovakia 

Cafius (Bryonomus) seminitens Horn and C. (B.) canescens 
Makl. are two very closely related species, both of which may 
occur at the same time in the same localities in California. To 
distinguish these two species from each other may often be very 
difficult, and mistakes in identification have often been made. 
In using existing keys and works of authors one is often at a 
loss to separate these two species in a large series of specimens 
due mainly to the individual variability of the shagreen on the 
shining spots of the head and thorax. 

Thanks to Mr. R. Q. Bliss of the Academy of Natural Sci- 
ences of Philadelphia and to Mr. R. L. Gillogly of California 
I received a large number of specimens of both species, and con- 
sequently was able to discover that the male copulatory organs 
constitute an excellent differentiating feature. Sketches of these 
parts of both species are presented herewith.

C. (B.) seminitens has the end of the aedeagus well rounded, 
the paramere stouter and a little shorter. In lateral view, the 
top also appears rounded. C. (B.} canescens, on the contrary, 
has an aedeagus with the top prolonged and pointed, and the 
paramere narrower. The lateral view shows a more swollen 
convex outline at the end of the outer side.

New World Apanteles Parasitic on Diatraea. 
(Hymenoptera: Braconidae) 

By C. F. W. MUESEBECK, United States National Museum 

The seven species of Apanteles treated here, of which three 
were previously described, develop in larvae of species of Diatraea 
that live in the stems of certain grasses. One of them, .ranthopns 
(Ashmead), is a solitary parasite ; all the rest are gregarious and 
their cocoons, when formed, are tightly packed in the host 
burrows. 

The following key will distinguish the seven forms. 

1. Propodeum with a broad, sharply margined areola, and 

with distinct costulae that set off large apical, lateral 

areas. A solitary parasite xanthopus (Ashmead) 

Propodeum without an areola or with a very narrow one 
that is usually poorly defined, and with no suggestion 
of costulae. All gregarious parasites 2 

2. Mesoscutum impunctate impunctatus Muesebeck 

Mesoscutum distinctly punctate, at least anteriorly 3 

3. Plate of first tergite narrowing conspicuously from mid- 

dle to apex ; tegulae pale 4 

Plate of first tergite parallel-sided from middle to apex ; 
tegulae black or blackish 5 

4. Hind femora black ; length about 3 mm. ; female an- 

tennae nearly as long as the body ; ovipositor sheath 

longer than hind tarsus minator, new species 

Hind femora yellow : length about 2 mm. ; female an- 
tennae much shorter than the body; ovipositor sheath 
not longer than hind femur sisaniae, new species 

5. Anterior and middle femora entirely yellow : hind femora 

piceous apically abditus, new species 

Anterior femora in part, and middle and hind femora 
entirely, black 6 

6. Plate of first tergite about twice as long as broad ; second 

flagellar segment of female antenna as long as first 
and twice as long as wide; ovipositor sheath longer 

than hind femur diatraeae Muesebeck 

Plate of first tergite three times as long as broad ; second 
flagellar segment of female antenna shorter than first 
and not nearly twice as long as wide ; ovipositor sheath 
shorter than hind femur deplanatus, new species

Apanteles xanthopus (Ashmead) 

Urogaster xanthopus Ashmead, 1900. Trans. Ent. Soc. Lon- 
don 1900, Pt. 2: 288. $. 

The type is from the island of St. Vincent. Numerous addi- 
tional specimens in the U. S. National Museum are labeled as 
having been reared from Diatraca saccharalis (F.) in Argen- 
tina, Uruguay and Brazil. Jaynes, 1933 (U. S. Dept. Agr. 
Tech. Bull. 363: 21), points out that the cocoons occur singly 
in the smaller tunnels of the host, indicating that only one para- 
site develops in a host larva, and suggesting further that the 
Apanteles attacks the very small borers "shortly after they enter 
the stalk, or possibly even before they actually enter it." 

This differs strikingly from all the other American species 
parasitic on Diatraea in its strongly sculptured and areolate 
propodeum. The thorax is not noticeably depressed ; the female 
antennae are fully as long as the body ; the mesoscutum is 
closely, finely punctate, confluently so anteriorly; the plate of 
the first tergite is nearly parallel-sided and about twice as long 
as broad at apex, and the ovipositor sheath is at least as long as 
the hind femur but decidedly shorter than the hind tibia. The 
legs, including all coxae, are yellow. 

Apanteles impunctatus Muesebeck 

Apanteles impunctatus Muesebeck, 1933. Proc. Ent. Soc. 
Wash. 35 : 194. J 1 $. 

This species is known only from the type series of 18 speci- 
mens which were reared from a single larva of Diatraea saccha- 
ralis (F.) in Louisiana. 

Apanteles minator, new species 

This is conspicuously the largest of the known American gre- 
garious species of Apanteles that parasitize Diatraea larvae. It 
differs further in its less strongly depressed thorax, and in its 
longer ovipositor sheath which is longer than the hind tarsus. 

Female. Length 3 mm. Head not broader than thorax; 
face only slightly convex, smooth and shining ; frons polished ;

finely longitudinally rugulose and with a shallow, longitudinal 
median impression ; plate of second tergite smooth and polished, 
slightly broader at base than long, defined laterally by strongly 
oblique grooves that diverge caudad, its posterior margin arcu- 
ate ; ovipositor sheath slightly curved downward at apex, a 
little longer than hind tarsus. 

Black ; antennae, labrum and mandibles brownish black ; 
tegulae transparent whitish ; wings hyaline, stigma and veins 
hyaline except stigmal margin, radius, intercubitus and stub of

Review 

BEITRAGE ZUR SYSTEMATIK DER LARVEN DER ITONIDIDAE 
(= CECIDOMYIIDAE, DIPTERA). Teil 1: Porricondylinae und 
Itonidinae Mitteleuropas, by Edwin Mohn. Zoologica, Band 
38, Lieferung 1, Heft 105, Lieferung 1 and 2, pp. 1-247, 30 
plates. 1955. 

In spite of the fact that there is an abundance of gall midges 
in Europe, and many are of economic importance, very few 
entomologists have turned their attention to a taxonomic study 
of the larvae of these insects. Dr. Mohn is presenting for the 
first time a comprehensive treatise on the larvae for the entire 
family Itonididae. Part 1 is a very admirable study of the sub- 
families Porricondylinae and Itonidinae, which comprise the 
vast majority of the family. (It should be mentioned that at 
the Copenhagen Congress, the International Committee on Zoo- 
logical Nomenclature ruled that a family name may be based 
on a genus placed in synonymy. Hence the Meigen 1800 names 
do not invalidate the better known family names in the Diptera, 
and Cecidomyiidae must replace the rather recent change to 
Itonididae. Similarly the Porricondylinae must revert to the 
Epidoseinae. However, the usage employed by Dr. Mohn is 
employed in this review.) 

Following a section describing the taxonomic features ex- 
hibited by the larvae, there is a brief section on their biology 
and ecology. The section on general taxonomy is a valuable 
contribution on comparative morphology as related to phylo- 
genetic relationships. On a basis of personal study, Dr. Mohn 
has been able to characterize 129 genera, while 15 other genera 
are included on a basis of published descriptions. Only 31 
genera that are known to occur in central Europe remain 
unknown. 

Keys are presented to the subfamilies and genera. It is par- 
ticularly noteworthy that this is the first time that keys have 
been prepared for the identification of the larvae of porricon- 
dyline, asphondyliine, oligotrophine, and lasiopterine midges. 

Although certain anatomical features of cecidomyiid larvae 
were first noted rather early in the eighteenth century, it was 



Ixviii] ENTOMOLOGICAL NEWS 27 

not until late in the nineteenth century that any attempt was 
made to present a diagnostic description. Shortly thereafter, 
J. J. Kieffer began to pioneer larval systematics, and in 1913 
he presented keys to many of the lestremiine and cecidomyiine 
genera. 

Dr. Mohn has provided the first comprehensive work on gall 
midge larvae since that by Kieffer. It is generally accepted that 
Kieffer maintained no collection, but Dr. Mohn was fortunate 
in having access to the valuable material of Riibsaamen. He 
was also able to study larval specimens from the extensive col- 
lection of Dr. H. F. Barnes and enlisted the aid of other 
cecidologists. 

The higher classification of gall midges until rather recently 
has consisted of three subfamilies, in one of which a few tribes 
were recognized. Enderlein (1936) recognized four subfami- 
lies and a very large number of tribes, his work, of course, being 
based on adult morphology ; but his classification, for the most 
part, has not been accepted. Limited contributions toward a 
suprageneric classification have more recently been made by 
F. W. Edwards; and M. J. D. White has made proposals based 
on cytological studies. 

This is the first attempt to further our knowledge of the 
phylogenetic relationships of the gall midges on a basis of mor- 
phological studies of the larvae. Dr. Mohn recognizes the four 
subfamilies of Enderlein. Furthermore, he recognizes within 
the Itonidinae the four supertribes of Enderlein. However, 
larval relationships are found to be strongly divergent to Ender- 
lein's opinions concerning tribes and subtribes. Rather than 
use formal names that might lead to confusion, Dr. Mohn has 
merely recognized a large number of generic groups to show 
immediate relationships. 

Thus, in this excellent monograph, a new tool has been used 
to clarify phylogenetic relationships within the Itonididae, keys 
have been presented to facilitate identification of the larvae of 
most of the middle European genera, and a diagnosis is given 
of each genus and many species. It is hoped that there will be 
no delay in Dr. Mohn's treatment of larval forms representing 
the rest of the family. A. EARL PRITCHARD

The NEW and the OLD join forces 
in the SECOND EDITION . 



A TEXTBOOK of ENTOMOLOGY 

By HERBERT H. ROSS, University of Illinois. 

THE NEW 

This second edition covers the recent advances in 
our knowledge of insect physiology, insect evolution, 
and insect biogeography and paleo-ecology. The au- 
thor has almost entirely rewritten the chapters on 
Arthropoda and their allies, the material on geological 
history, and many sections on physiology. The new 
version includes enlarged and reworked keys to orders 
of insects. Entire new sections on aquatic insects and 
many new drawings have been added as well. In addi- 
tion, much of the author's coverage of the ecological 
aspects of the subject has been changed in the light of 
current ideas. 

THE OLD 

This text will continue to provide students with a 
broad introduction to the basic fields of entomology- 
including morphology, physiology, taxonomy and ecol- 
ogy. The author also continues to stress the integra- 
tion of entomology with the general concepts of biology. 
He presents his material in an evolutionary manner 
wherever possible, so that the student may acquire a 
unified picture of the subject as a whole. 

THE COMBINATION 

forms a superior text, ideal tor classroom use.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphacschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Mannaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

How Much do You Pay for Your Fun? 

By MAURICE E. PHILLIPS 

This may seem a light subject for the News, but a very serious 
matter is involved. Pure scientific research, so-called, has al- 
ways been considered by its devotees as an inviolable field- 
akin to a man's religion. It is the fiber of which our journals 
are made. 

Of those who contribute papers to such periodicals a ques- 
tion might be asked : why did you become an entomologist, a 
botanist, an ichthyologist? That you are definitely character- 
ized in moving pictures and on television as something of a 
freak, and as a harmless screw-ball by the public at large must 
mildly fret you at times. But I now ask this question and in- 
vite you to join me in seeking an answer. 

For our present purposes it will do you no good unless you 
seriously indulge for a time in a little introspection ; forget the 
standard answers and get down to brass tacks why did you? 
There must be good reasons, worth-while compensations. 

There are several fairly obvious possible replies to the ques- 
tion we have asked. Could the answer lie in the field of our 
personal economics do we expect to get rich at it? This seems 
hardly likely. The number of pure research scientists who 
amass a fortune by their endeavours is small indeed. They usu- 
ally make an adequate living, but I know many who draw a 
smaller wage than a first-class union plasterer. The average 
young research scientist just starting his career, has spent seven 
or eight expensive years of his time and effort in college he is 
an intelligent young man or he would not be where he is today.

30 ENTOMOLOGICAL NEWS [Feb., 1957 

With his natural talents and the same amount of time spent in 
business training, he could go places in the business world. 
Money, therefore, seems hardly the answer. 

Could it be that there are involved here various aspects of 
nobility and self-sacrifice? Are we throwing our considerable 
talents into the pot for the uplift of mankind for sweet char- 
ity's sake? In many years' association with universities and 
research institutions, I have known hundreds of research scien- 
tists. On the whole they are as fine a group of people as you 
can find anywhere. They don't beat their wives, they love their 
children, they go to the polls, and they come as near living by 
the Golden Rule as any segment of society you are apt to exam- 
ine. But I have never observed in them any very obvious force 
driving toward humanitarian uplift. They know, of course, that 
a project on which they are working, and which may have no 
apparent practical value, may some day turn out to have one, 
but it would be gambling their time to assume it and they are 
not a race of gamblers. 

What do we have left then ? It may be heresy even to think 
it, but the most apparent answers are : fun and glory. These 
may seem cynical answers, but they are human ; they may sug- 
gest clay feet, but who can cast stones at clay feet? There can 
be no question but the research scientist looks with high ap- 
proval at his name on papers with more approval yet if it is 
oh many papers. I do not condemn this ; I have felt the tug 
myself. The number of his readers will not be large his works 
are not best sellers, but the approval of his fellow scientists is 
one of life's sweetest treasures. 

But the big pay-off for the research scientist is fitn he really 
has it. Many of the world's greatest have no hobbies but their 
work. They live and breathe it; they eat with it; they take it 
home in brief cases, satchels and bags ; when not doing it they 
talk about it most of their waking time. They would be very 
unhappy and neurotic if their fathers had insisted they be me- 
chanics. Some have never learned how to dance, it is a waste 
of time to go to the movies ; anyway they are having too good 
a time with their research it is their recreation, their amuse- 
ment. If you have never been one you will never know the 



Ixviii] ENTOMOLOGICAL NEWS 31 

pull of the unknown, the lift from finding out, and adding to 
the "sum-total of human knowledge." If you arc one of these 
lucky people, how much are you paying for your fun? The 
budget experts concede that it is just and proper to expend at 
least 5% of your income for amusement and recreation. 

It is unquestionable that a tradition has grown up that after 
a scientist has devoted his skills to doing a piece of research, it 
is his just due that it be published at no cost to him. This, 
even though a mass of such published work may immeasurably 
increase his scientific stature and, to a considerable extent his 
salary. 

Entomological News is one of the many journals, which as 
the organ of an independent society, is feeling the pinch in the 
matter of imposing no amusement tax on its authors. An anal- 
ysis of the 1956 volume, exclusive of the December issue, reveals 
that of the general papers on taxonomy, ecology, morphology, 
life histories, etc., eight were by members of the Society, and 
contained a total of approximately 29 pages. Forty papers by 
36 authors with a total of 166 pages are by authors who are 
not members, and who consequently contributed nothing except 
the minor cost of engraving to the operation and maintenance 
of the Nc^vs. That is, the strictly scientific material was made 
up of approximately 15% member papers, and 85% non-mem- 
ber. Who paid the bill? It has largely been paid over the 
years by resident members, in time and work, and in financial 
contributions to permanent funds. The drudgery of editorial 
work has been donated ; the building up of what permanent funds 
there are has been a long, slow arduous task, but with increasing 
costs these are not now enough. 

If your name has appeared often as an author over a period 
of years, the Society may have put up some thousands of dollars 
for you. If authors paid one-fourth of the cost of printing their 
papers, the News would again be in the black. It is as simple as 
that. How much are you paying for your fun? 



Any donation you might care to make toward the expenses 
of publishing the News will be gratefully received. It should

be addressed to the AMERICAN ENTOMOLOGICAL SOCIETY, 1900 
Race St., Philadelphia 3, Pa. You may designate its use for

Diptera (Calliphoridae, Heleidae and Chloropidae) 
Collected from Birds' Nests at London, Ontario 

By W. W. JUDD, Department of Zoology, University of Western 
Ontario, London, Ontario 

In an earlier communication (Judcl, 1954) a report was pre- 
sented on insects collected and reared from nests of birds in the 
vicinity of London, Ontario during 1951-1953. These studies 
were continued in 1955 and among the insects collected were 
several flies which were kindly identified by two taxonomists of 
the United States National Museum, C. W. Sabrosky (Calli- 
phoridae and Chloropidae) and W. W. Wirth (Heleidae). 

Calliphoridae 

Many blowfly larvae were collected from nests when these 
nests were examined on the day that the last of the young birds 
left each nest. The larvae were put into jars with part of the 
fabric and debris from the nest ; and as the adult flies emerged 
they were pinned and the dates of their emergence were re- 
corded. 

Protocalliphora sp. (sialia S. and D.?) : 

All the blowflies reared were identified as Protocalliphora, 
probably sialia S. and D., but Mr. Sabrosky pointed out (in lit.) 
that they represent a complex of species still requiring revision. 
The larvae were taken from three nests of robins (Turdus mi- 
cjratorhis) and one of a brown thrasher (To.vostoina rufiuii). 

1. Robin This nest, in the crotch of a Manitoba maple, con- 



Ixviii | ENTOMOLOGICAL NEWS 33 

tainecl four young birds on May 16. One bird was gone on May 
18 and two others departed on May 20, leaving the fourth bird 
dead in the nest. The nest yielded 54 larvae. Twenty-seven 
flies were reared : 3 June 3 ; 1 5 June 4 ; 7 June 5 ; 2 June 
6. 

2. Robin This nest, in a bush of twin honeysuckle, contained 
two eggs on May 12, three on May 13 and four on May 14. 
There were four young birds on May 27 and they left the nest on 
June 6, when 40 larvae were collected. Only three flies 
emerged : June 20. 

3. Robin This nest, in a grape vine twining through an 
apple tree, contained one egg on May 30, and two eggs on June 
7. Two young birds were present on June 14 and they de- 
parted on June 23, when 8 larvae were found in the fabric of 
the nest. Seven flies emerged on July 4. 

4. Brown Thrasher This nest, in a bush of twin honey 
suckle, contained one egg on May 11, two on May 12, three on 
May 13, four on May 14 and five on May 17. Four eggs 
hatched on May 27 and the fifth on a later date, and the five 
young birds left the nest on June 7, when 4 larvae were found in 
it. Three flies emerged on June 21 and a fourth on June 22. 

The 41 flies are retained in the U.S.N.M. Protocalliphora 
sp. (near sialia S. and D.) was reared at London in 1952 from 
nests of the red-winged blackbird (Judd, 1954). 

Heleidae 
Culicoides travisi Vargas : 

A nest of a catbird (Dinnetclla carolinensis) , in a barberry 
bush, contained three catbird eggs and one cowbird egg on May 
30. The cowbird egg was missing on June 7. The last of the 
young catbirds left the nest on June 23, when a female C. twist 
was found in the fabric of the nest. The specimen is retained in 
the U.S.N.M. Flies of the genus Culicoides have previously 
been reported in nests of crows in Montana ( Jellison and Philip, 
1933) and in the nest of a catbird at London (Judd, 1954). In 
the latter case the flies were engorged with blood. 



34 ENTOMOLOGICAL NEWS [Feb., 1957 

Chloropidae 

Oscinella luteiceps Sabrosky : 

A nest of a catbird, in a bush of black-berried elder, was com- 
plete on May 23. Four eggs were laid in it successively on May 
27, 28, 29 and 30. Two birds hatched on June 11, a third on 
June 12 and the fourth on June 13. All four birds left the nest 
on June 23, when one fly, O. luteiceps, was found in it. The 
specimen is deposited in the collection of the Department of 
Zoology, University of Western Ontario. One of the paratypes 
from which this species was described was collected at London 
(Sabrosky, 1940).

Distribution of Dermacentor variabilis (Say), the 
American Dog Tick, in New Hampshire 

By R. L. BLICKLE and J. G. CONKLIN l 

The published records for the distribution of Dermacentor 
variabilis (Say) for New Hampshire as are follows: Bishopp 
and Smith (1936), Bishopp and Smith (1938), Bishopp and 
Tremblay (1945), and Smith ct al (1946) for the central and 
southwestern part of the state, all based on collections of the 
Bureau of Entomology and Plant Quarantine made in 1936. 
Bequaert (1947) published a record for Ossipee, a town in the 
east central part of the state. 

Recent collecting and a study of the records in the collection 
of the University of New Hampshire show D. variabilis to be 
well established in at least nine towns. There are additional 
records for ten other towns. However, the data is such that,

for the present, these are considered to be stray collections rather 
than established foci. 

The following areas are considered to have established foci 
of tick infestations. These records are in addition to the ones 
published by the above authors. Central area : Moultonboro 
(April 8 to June 20, with tick drag) (18 July, 1949, on fox, 
D. L. Collins coll.) ; Sandwich (April 19 to May 20, on dogs) ; 
Tuftonboro (May 25, with tick drag) ; Wolfeboro (May, on 
man) ; New Durham (May to July, on man) ; Center Harbor 
(18 July 1949, with tick drag, D. L. Collins coll.) ; Ossipee 
(May 30, on man); southern and southeastern area: Dover 
(May and June, on dogs) ; Amherst (July, with tick drag). 

Four towns from which ticks have been recorded, namely, 
Conway, Eaton, Freedom, and Barnstead, probably have estab- 
lished infestations since they border the central area. The six 
towns from which ticks have been recorded but are not con- 
sidered to have established foci are Concord, Dublin, Jaffrey, 
Laconia, Lancaster, and Sutton. 

The main area of infestation is in the central and east central 
part of the state. This area is bounded by Lake Winnipesaukee 
on the west and extends eastwartlly into Maine. In the past 
twenty years, from 1936 to 1956, the infested area has increased 
from approximately 100 square miles to an area of at least 400 
square miles. Throughout this area the ticks are confined to 
the grassy areas, or to the low vegetation and pine woods adja- 
cent to the grassy area. If the infested area in Maine is in- 
cluded the total infested area would be approximately 1000 
square miles and would extend to Lake Sebago. 

The infestation is quite heavy in some parts, notably along 
Shannon Brook and along parts of the lake shore in the towns 
of Moultonboro and Tuftonboro. In May 1952 the above areas 
showed a population of one tick per square yard when a tick 
drag was used for sampling. However, most of the samples 
taken in other localities showed a considerably smaller popu- 
lation. 

How and when the infestation in Moultonboro and Tufton- 
boro started is rather obscure. The local inhabitants claim. 



36 ENTOMOLOGICAL NEWS [Feb., 1957 

probably through prejudice, that a certain individual brought 
the ticks in when he pastured sheep on the land. This so-called 
introduction of ticks occurred approximately thirty years ago. 
It may be that the increase of ticks coincided with the introduc- 
tion of sheep and the residents associated the two occurrences. 
Smith et al. (1946) state, "A small area of infestation occurs 
around Lake Winnipesaukee, N. H., with indications that in 
certain localities it has persisted there for at least several dec- 
ades. In other localities the infestation is apparently recent, 
and may have been caused by the transportation of infested 
dogs by vacationists." 

The infestation in the town of Amherst is of recent origin, 
and was started, presumably, by the introduction of ticks on 
dogs. This infestation is confined to two or three farms. A 
family living in this area traveled, frequently, between Cape 
Cod, Mass., and the farm in question. The family dogs were 
carried back and forth on these occasions. There is no history 
of ticks previous to the family's moving into the area, and since 
the infestation is limited to this and adjoining properties, it 
seems safe to assume that the infestation was started in this 
manner.

The Immature Stages and Female of Polypedilum 

(Polypedilum) obtusum Townes (Tendi- 

pedidae: Diptera) 

By JAMES E. SUBLETTE, Northwestern State College, 
Natchitoches, Louisiana 

Several adult male and female midges were reared from ma- 
ture larvae collected in Little Bayou Pierre, a small, clear, 
sandstone-rubble bottomed stream of the Kasatchie Wold in 
West-Central Louisiana. The adult males agreed with Townes' 
(1945) description in all respects except size. Measurement 
of seven specimens gave: mean wing length, 1.73 mm.; stand- 
ard deviation, .55 mm.; range, 1.6-2.1 mm.; mean leg ratio, 
1.68; range, 1.37-1.93; the antennal ratio, 1.95 (mean of two 
specimens only). Townes lists these measurements for this 
species as: wing, 2.2 mm. long; leg ratio, 1.75; and antennal 
ratio, 2.0. Although a size difference exists, P. obtusum has 
such distinctive male genitalia that there can be no doubt as to 
the identity of these specimens. Eight females having the same 
identical immature stages as the males of P. obtusum were 
reared from the same material and undoubtably belong to that 
species. 

Female. Coloration and general body features same as male 
except that abdomen of female has a definite light green color 
instead of a very faint green color. Mean wing length, 1.8 mm. ; 
standard deviation, .34 mm.; range, 1. 4-2 .4 mm.; mean leg 
ratio, 1.83; range, 1.67-1.96. 

Larva. Total length (mean of two mature specimens), 5.4 
mm. ; head length, .45 mm. Color, pale yellowish-green ; head 
capsule, very lightly colored with only tips of mandibles, la- 
bial plate and ventral part of occipital area darkened. Labial 
plate (Figure 1) very closely resembles that of P. conviction 
(Walker) as illustrated by Johannsen (Plate V, Figure 76, 
1937). Paralabial plates (Figure 1), finely pointed at both 
ends, with about 28-30 coarse striae. Posterior margin of para- 
labial plate very strongly arched, apparently more so than other 



38 ENTOMOLOGICAL NEWS [Feb., 1957 

described species of this genus. Antennal ratio, 56:20:5:6:5. 
Antennae slightly longer than mandibles and have a mean ratio 
of 21 :22. Antennal blade reaches tip of fifth segment or very 
slightly exceeds it (Figure 3). Mandibles (Figure 2) are 
blackened at tips with usual preapical comb and compound 
brush ; accessory tooth of mandible reaches tip of first free 
tooth ; basal tooth fused with distal end of the mesial shelf of 
mandible. Epipharyngeal comb has 13 teeth arranged in three 
groups, a central group bearing 3 teeth and two lateral groups 
with 5 teeth each. Lateral to epipharyngeal comb are about 
6 long slender blades ; posterior ventral surface of labrum bears 
broad median pectinate blade which is rounded on free border ; 
anteriorly, two pairs of socketed pectinate blades, most anterior 
pair being smaller ; lateral, inferior surface of labrum with 5 
heavy curved pectinate bristles on each side. Premandibles 
with tips bifid and darkened. Maxillary palpus inconspicuous, 
3 segmented ; basal segment slightly longer than remaining two ; 
basal segment bears about 5 blades at apex. The rather small 
rounded eye spots (diameter about one third the length of the 
mandible) are contiguous. Anterior prolegs are composed of 
two dense tufts of long slender claws ; posterior prolegs are 
short and terminate in a group of pale hooked claws. Each pre- 
anal papilla bears 8 bristles ; on anterior surface is a bristle. 
Two anal gills, about half as long as prolegs, each constricted 
and tapering beyond middle ; anterior to gills are two strong 
bristles. 

Pupa. Total length (mean of two specimens), 4.4 mm.; 
respiratory organs not clearly discernible on mounted slides. 
Second abdominal tergite with anterior, inconspicuous band of 
erect denticles, posterior margin with up to 30 dorsally turned 
black hooks ; segments 3-6 with distinct anterior and posterior 
bands of suberect, barbed denticles, the anterior and posterior 
bands being broadly joined along the mid-dorsal line by a broad, 
fenestrated band of the same denticles. Segments 7 and 8 with 
a greatly reduced anterior band only. Lateral margin of seg- 
ment 5 and 6 with 3 lateral bristles; segment 7 with 4 bristles, 
the anterior 2 broadly separated from the posterior 2 ; eighth

not certain that the larvae of the two can be separated unless 
size and the greatly arched posterior margin of the paralabial

of two characters : tergal armature and features of the posterior- 
lateral spur of segment 8. The females do not appear to have 
any diagnostic features which will separate them from other 
members of the convictum group. 

The occurrence of Polypcdiluni obtusum in Louisiana repre- 
sents a new state record and a considerable extension of range 
as the species has been previously reported only from New York 
and Michigan (Townes, 1945).

Two Early Entomological Collectors in Colorado 

By F. M. BRONVN, Fountain Valley School, Colorado Springs 

While engaged upon a search for the source of W. H. Ed- 
wards' Kansan co-type of Coenonytnpha ochracea I have un- 
earthed information that may be of assistance to others who are 
interested in material collected during 1858-1863 in what is 
now the state of Colorado. First let me review some of the 
history of the area. During the period under consideration the 
region around Denver and Colorado Springs, Colorado, was 
first a part of Kansas Territory and then part of Colorado 
Territory. During the time it was part of Kansas Territory 
the western boundary of that Territory was the Continental 
Divide. When the Colorado Territory was established in Feb- 
ruary 1861 the western boundary of Kansas was moved east- 
ward to about the 102nd meridian. 

In 1859 there was considerable effort on the part of the 
residents of Kansas living west of Denver in the mining camps 
to establish there the Territory of Jefferson. To the south, in 
the Pikes Peak region, later to center on Colorado Springs, the 
residents wanted the new territory to be called Colorado. In 
the end the Coloradans won but from 1859 to 1861 the advo- 
cates of the Territory of Jefferson were militant and used 
that name. 

The first entomologist to visit the region was Thomas Say 
who accompanied Major Stephan H. Long to the Rocky Moun- 
tains in 1819-1820. His collections were stolen by a pair of 
packers on the return journey. The next generally accepted 
collector in the region is James Ridings of Philadelphia who 
visited the Denver region in 1864, a few years after Colorado 
became a territory. In 1866, Tryon Reakirt compiled the first 
list of Colorado butterflies upon the strength of Riding's collec- 
tion and those in the hands of members of the Entomological 
Society of Philadelphia and in the Society cabinet. 

A careful study of Reakirt's paper and of several earlier ones 
by William II. Edwards and others yields plenty of evidence 
that there were earlier collectors in the region than Ridings. 



42 ENTOMOLOGICAL NEWS | Feb., 1957 

Two of these earlier Collectors, Winslow J. Howard and Wil- 
liam S. Wood, Jr., were early members of the Entomological 
Society of Philadelphia. There is a suggestion that there was 
at least one other, but as yet I have no inkling who he was. 

WILLIAM S. WOOD, JR. 

According to Ewan (1950, p. 340), Wood was a member of 
the expedition led by Lieutenant F. T. Bryan, U. S. A., to scout 
a wagon road from Fort Riley, Kansas, to the Great Salt Lake 
over Bridger's Pass in 1856 and 1857. James Cooper, the 
ornithologist, was surgeon for this party. Hume (1942, p. 41) 
in his account of Cooper states that the party disbanded upon 
reaching the Rocky Mountains without fulfilling its mission. 

There are three primary sources of information about the 
naturalists and collectors who accompanied the military expedi- 
tions of this era : The published reports of the War Depart- 
ment ; those of the Smithsonian Institution ; and, Prof. Spencer 
Fullerton Baird's fabulous correspondence files in the Smith- 
sonian Institution. In the Annual Report of the Smithsonian 
Institution for 1856 (Baird, 1857, p. 64) is this entry: "Lieu- 
tenant F. T. Bryan, U. S. A., Six boxes, one keg containing 
alcoholic specimens, birds, mammals, and skeletons, from United 
States wagon-road to Bridger's Pass." There is no reference 
to insects collected. In the Report for the next year (Baird, 
1858, p. 50) I found: "Lieutenant F. T. Bryan, U. S. A., Three 
boxes of zoological specimens collected by William S. Wood on 
the wagon-road expedition from Fort Riley to Bridger's Pass." 
On the following page acknowledgment is made of Cooper's 
material collected from Fort Laramie back to Independence, 
Missouri. 

The earliest extant correspondence between Wood and Baird 
is a letter dated February 19, 1857. This is No. 221 in Baird's 
letter-press book for 1857. It reads : 

"February 19, '57 
"My dear Mr. Wood 

"The wagon route you saw announced is not under charge 
of the War Dept. but under that of the Department of the 



Ixviii] ENTOMOLOGICAL NEWS 43 

Interior. Lt. Bryan will not have charge of it. As soon as 
an opportunity presents itself however, I will try to find you 
a good place on one or other of the exploring parties. We 
shall know about them in about three weeks. 

"I have deposited your eagle in the Mechanics Institute fair 
here, in your name, for competition as a specimen of taxidermy. 



"Wm. S. Wood 
"Phila." 



'Yours truly 

ss/ Spencer F. Baird 



In a letter dated April 24, 1857, Baird offered Wood a post 
with Lt. Bryan. One dated July 12, 1857, and addressed to 
Wood at Fort Kearney, N. T. (Nebraska Territory), is ample 
evidence that Wood was on the 1857 field party but most likely 
not with the party in 1856. There is no evidence that Wood 
penetrated the area now included in Colorado while on the 1857 
Bridger's Pass Wagon Road Expedition. His collections for 
that year in all probability were made along the Platte River 
in Nebraska, in eastern Wyoming, and around Fort Laramie. 

In March 1859 there was an extended correspondence be- 
tween Baird and Wood about the Landeges wagon road party 
bound for the Great Salt Lake and about Lt. Mullen's wagon 
road party exploring the route between Walla Walla, Wash- 
ington, and Fort Benton, Montana. At this time Wood was 
living on Oak Street at the corner of Rose Street in West Phila- 
delphia. Wood had been idle for some months and was anxious 
to get into the field on a collecting expedition. A letter from 
Wood dated March 28, 1859, told Baird that arrangements had 
been made to go west on a collecting trip for another group. 
Baird was so irate about this that he struck Wood from the 
rolls of field collectors for the Smithsonian and there is no 
further correspondence between the two. 

The 1859 collecting trip to the west may well have been 
undertaken for the Entomological Society of Philadelphia. 
Both Charles J. Wood and William S. Wood are listed by 
Cresson (1909, p. 51) as "Organization Members" of the So- 
ciety. They attended the meeting held on March 1, 1859, and 



44 ENTOMOLOGICAL NEWS [Feb., 1957 

it was shortly after this that William Wood wrote to Baird 
telling him that he could not accept Baird's proposal since he 
had accepted a $60.00 advance to go west for another group. 

Where did Wood go in 1859? Edwards in his description 
of C alias Alexandra (1863, p. 15) states: "From Pikes Peak; 
in the Society's collections ; 6 males, 1 female. The second 
female is from the collection of Mr. George Newman and was 
taken among the Rocky Mountains, some years ago, by Mr. 
Wood." There are other similar citations that link "Mr. 
Wood" and "Rocky Mountains." There is no doubt in my 
mind that "Mr. Wood" is William S. Wood, Jr. In 1859 there 
was only one place that a person from the East not attached 
to a government party could use as a base for operations in 
the Rocky Mountains. That was the vicinity of Denver. There 
were several flourishing mining camps in the mountains con- 
nected with Denver City on the plains by wagon roads and good 
horseback trails. The settlement of Colorado City in the 
shadow of Pikes Peak was just forming and the chances that 
Wood visited it and not Denver are very slight. Bird speci- 
mens collected by Wood tie him to the Clear Creek area west 
of Denver. Travel was slow except to the mining camps west 
of Denver. With limited time and virgin territory, I am sure 
that Wood confined his travels to the region delimited by 
Denver, Golden, Empire and Central City in Colorado. All 
of his insect specimens were labelled "Rocky Mountains." 

I have been unsuccessful in finding biographical material 
about Wood. He was the son of an Englishman, William S. 
Wood, who had leanings toward natural history. Mr. Wood, 
Sr., may have been a taxidermist. I know that he sent bird 
skins to the Smithsonian Institution (Baird, letter June 26, 
1858). William, Jr., in addition to being a member of Lt. 
Bryan's expedition, was a member of the Naval Expedition to 
New Grenada, Colombia, under Lt. Muhler in 1857-1858. On 
this trip he was accompanied by his brother Charles. Another 
brother, Christopher, accompanied the Naval expedition to the 
Rio Plata in southern South America in 1858. I have no in- 
formation about William, Jr., between 1859 and 1878 when he 



Ixviii] ENTOMOLOGICAL NEWS 45 

was listed as a taxidermist in Wilmington, Delaware, first at 
903 Market Street and later at 402 East llth Street. He drops 
out of sight again after 1884 (Hindes, letter June 14, 1956). 
Frank Morton Jones, the dean of Delaware naturalists, was 
unable to give me any information to add to what I had. 

WINSLOW J. HOWARD 

It will be noted in Edwards' description of alexandra cited 
and in part quoted above is the locality "Pikes Peak." There 
are many specimens in the collections of the Entomological So- 
ciety of Philadelphia that bear this label. I had been misled 
by Reakirt's article about Colorado butterflies and by references 
by Edwards in "Butterflies of North America" into thinking 
that Ridings was responsible for these captures. Since there 
are a number of citations of the locality in the literature before 
Ridings set out on his trip someone else must have collected 
the specimens. 

I have found that some of these "Pike's Peak" specimens are 
credited to "Howard." The solution of the question of who 
"Howard" was is found in an article on Hymenoptera by 
Cresson (1863, p. 73) where in stating the type locality of 
Masaris vespoides he wrote : "Hab. Pike's Peak. Collected by 
Mr. Winslow J. Howard." The history of the American Ento- 
mological Society written by Cresson (1909) for its fiftieth 
anniversary includes among the members "Howard, W. I., Cen- 
tral City, Colo., March 10, 1862." As far as I know this makes 
Howard the earliest resident entomologist in Colorado. 

Who was Howard? Ewan (1950, p. 235) notes very briefly 
that he sent some specimens of plants from Montana to Asa 
Gray at Harvard University in 1866. Dr. C. E. Kobuski 
(letter, April 13, 1956) could find no mention of Howard in 
the archives of the Gray Herbarium. In the literature of 
entomology there are scattered references to specimens collected 
by Howard outside of Colorado. These almost invariably place 
him in Prescott, Arizona, during the 1870s. Inquiries in Pres- 
cott drew a blank. Howard's constant association with mining 
camps led me to suspect that he was a mining engineer or at 



46 ENTOMOLOGICAL NEWS | Feb., 1957 

least associated with that industry. He was, but in a most 
indirect way. Looking for information about him I ran into 
more blind alleys than I care to mention. At last in the West- 
ern History section of the Denver Public Library I struck 
pay-dirt. 

While scanning the earliest newspapers printed in Colorado 
for mention of Howard's name I found in The Western Moun- 
taineer for July 19, 1860, this article : 

"Watches and Jewelry We solicit your special attention to 
the advertisement of W. J. Howard, Esq., which appears in this 
issue. Mr. Howard was formerly in the leading establishment 
in his line on the continent that of Messers Tiffany & Co., 
New York City and we are able to assure our readers from 
personal knowledge that any work entrusted to him will be 
skillfully and properly done. He has a rare collection of the 
natural curiosities of the Rocky Mountains, which will be found 
very entertaining to those interested in natural science. Give 
Mr. Howard a call, and if you have any interesting specimens 
of the mineral wealth of the country, take them with you." 

Although the newspaper quoted was published in Golden 
City, J. T. (Jefferson Territory), Howard's business was lo- 
cated on the east corner of Larimer and F Streets in Denver 
City. As late as December 20, 1860, Howard's advertisements 
appeared in The Western Mountaineer. We know that Howard 
gave Central City as his residence when he applied for member- 
ship in the Entomological Society of Philadelphia (later the 
American Entomological Society) in March 1862. Probably 
he moved there during the summer of 1861. In Central City 
he established Howard and Colony, manufacturing jewelers. 
The advertisements for this concern appear as late as January 
4, 1865, in the daily Rocky Mountain Nezvs, the first news- 
paper published in Denver and still active. 

Apparently Howard moved back East late in 1865. The 
February 27, 1866, issue of the Rocky Mountain News carried 
a note from a returning Coloradan that Howard was living in 
Brooklyn, New York, and had married. Howard returned to 
the West that autumn. The Rocky Mountain Nczvs for Oc- 
tober 15, 1866, noted his arrival on the H. O. M. & Ex. Co. 



Ixviii] ENTOMOLOGICAL NEWS 47 

stage from the East and that he registered at the Pacific House 
in Denver on the 14th. On the next page is this note: "W. J. 
Howard . . . collector of botanical, mineral and entomological 
specimens, called on us today. He arrived from the East by 
the last coach and goes on to Montana tomorrow." There my 
knowledge of Howard stops. I am anxious to get further infor- 
mation about the movements of both Wood and Howard in the 
West.

Known Distribution of a Bat Flea, Nycteridopsylla 
chapini Jordan (Siphonaptera: Ischnopsyllidae) 

By ROBERT E. LEWIS, Department of Entomology, 
University of Illinois 

The brown bat flea, Nycteridopsylla chapini Jordan, is now 
known from several widely distributed areas of the United 
States east of the Great Plains. Originally it was described 
from Glen Echo, Maryland, by Jordan (1929). The type speci- 
mens were taken from the big brown bat, Eptesicus fuscus 
(Beau.), and were collected by R. C. Shannon in 1916. Vernon 
Bailey collected N. chapini from the Indiana bat, Myotis sodalis 
Miller and Allen, taken at Colossal Cave, Kentucky. M. W. 
Sanderson took N. chapini from the type host from a cave in 
Benton County, Arkansas. Lane (1953) noted the collection 
of a single female from the type host in Hocking County, Ohio, 
in 1951. The latest record is that of one male and four females 
collected by R. F. Myers from a male of the type host collected 
in Pulaski County, Missouri, in 1955. 

This determination was confirmed by Dr. G. P. Holland, 
Department of Agriculture, Division of Entomology, Ottawa, 
Ontario, Canada, and one male and one female were deposited 
with him. Of the other three, two are housed in the collection 
of the Illinois Natural History Survey, and the remaining one 
is in the collection of the Department of Entomology, University 
of Wisconsin, Madison, Wisconsin. 

Miller and Kellogg (1955) list the distribution of Eptesicus 
fuscus fiiscus (Beau.) as: "Eastern North America, west ap- 
proximately to longitude 102W., from Quebec, Ontario and 
Manitoba south to northern Florida and Nuevo Leon, Mexico." 
If one considers the other eight subspecies of Eptesicus fuscus 
as well as the additional four species of the genus which occur 
in North and Central America, it seems reasonable to assume 
that further collections will extend the known range of this flea 
to the west. It is doubtless a much more common species than 
its presence in collections would indicate (Holland, 1956).

Hermann Weber (1899-1956) 

Professor Dr. Hermann Weber, a Corresponding Member of 
the American Entomological Society, died November 18, 1956, 
at Tubingen, Germany, a few days before his 57th birthday. 
Although without doubt one of the really important entomologists 
of the present century he was hardly known personally in this 
country. Dr. Weber apparently never visited America, al- 
though he did correspond with a number of American morpholo- 
gists. From Dr. A. Glenn Richards, Entomological News 
learned of Weber's death, and from Dr. R. E. Snodgrass we 
were able to learn of his serious illness for the past year or more. 
Dr. O. A. Johannsen was able to tell us of a brief but pleasant 
visit at Weber's home in Danzig many years ago, and of their 
discussion of certain morphological problems. 

From an examination of Kurschner's Gelehrten Kalender for 
1954 we learned that Weber was born in Bretten, Baden, No- 
vember 27, 1899, and that before coming to Tubingen in 1950 to 
become Professor and Director of the Zoologisches Institut of 
the University of Tubingen, he had taught at Bonn, Danzig, 
Freiburg, Miinster, Wien. and Strasbourg. He was awarded 
the Fabricius Medal by the Deutsche entomologische Gesell- 
schaft, was an Honorary Member of the Royal Entomological 
Society of London, and of the Osterreichsche Akademie der 
Wissenschaften. 



50 ENTOMOLOGICAL NEWS [Feb., 1957 

However meager our information regarding Weber as a 
person, we know a great deal of him as a scientist. He is per- 
haps best known as the author of the "Lehrbuch der Ento- 
mologie," (1933), generally considered the finest textbook of 
entomology ever written, despite the fact that the author was 
only 33 years old when it appeared. Quoting from Dr. Snod- 
grass' review, in Ent. News 44 : 166-168 : "The book is not 
only predominantly morphological in the sense that it deals 
largely with structure and the homologies of structural parts, 
but it is morphological from the viewpoint that anatomical form 
is an adaptation to function. In other words, the morphology 
of insects becomes a part of the biology of insects, as it properly 
should be. ... The subject of insect morphology, as demon- 
strated by Dr. Weber's book, has now reached a stage in which 
it may rightly assert its ability to render the fundamental serv- 
ices that should be expected of it to the other branches of en- 
tomological science, particularly, in taxonomy and insect re- 
lationships, physiology, and ecology." And, we may add, this 
same approach to morphological studies is characteristic of 
Weber's other writings, that the structures are expressive of 
the life of the insect and necessarily tied to function and to 
ecology. 

Another textbook, "Grundriss der Insektenkunde," appeared 
in 1938 and was intended as an introduction to entomology. 
The second edition and third edition were much enlarged, es- 
pecially in areas in which research had progressed rapidly in 
recent years. This was desirable because the "Lehrbuch" of 
1933 had been long out of print, and the work on a proposed 
revision still incomplete. The third edition (Gustav Fischer 
Verlag, Stuttgart, 1952) is noteworthy for the clear and concise 
accounts it gives of the recent work in the field of experimental 
embryology (Seidel, Bock, Krause), of the many studies on 
insect hormones, and of the work of Henke, Stossberg, Suffer!, 
etc., on development of butterfly scales and wing pattern, and 
of many other matters otherwise available only in lengthy 
original papers. 

Of great value also are Weber's review articles that appeared 



Ixviii] ENTOMOLOGICAL NEWS 51 

in Fortschritte der Zoologie, in 1939 and 1942 (Vols. 4 and 9). 
In the latter he provides critical reviews of recent works deal- 
ing with the morphology, histology, and development of all 
articulates. In the first 31 pages he gives a complete and very 
clear discussion of the theories of head segmentation and comes 
to a series of conclusions as regards possibilities, but finds more 
information is necessary to provide a theory applicable to an- 
nelids as well as arthropods. In the same way, the thorax and 
abdomen are covered, and the histology and functioning of the 
various internal systems and organs. 

Another large general work is the "Biologic der Hemipteren" 
(1930), regarding which we may again cite Dr. Snodgrass 
(Ent. News 41 : 275-276) : [It] ". . . is without question one 
of the best publications of recent times in biological entomology. 
Within it the writer brings together not only a review of all that 
has heretofore been written on the life and structure of the 
Hemiptera, but also the results of his own extensive and minute 
studies of the complex hemipterous mechanisms that for a 
century have baffled the skill of insect anatomists." 

A glance through the Zoological Record for the years 1923 to 
1953, shows that Weber also published a large number of re- 
search papers making up an additional 1500 odd pages in Zool. 
Jahrb. (Anat.), in Zeitschr. Morph. Okol. Tiere, in Zeitschr. 
vergl. Physiol., in Zool. Anz., and in other journals. These 
researches deal with the morphology of the head and thorax in 
various groups, as a contribution to general morphology, and 
with detailed investigations on the anatomy, particularly of the 
mouth parts, on the physiology of sucking, and on the sensory 
physiology of a number of homopterous species and the Anoplura. 

Noteworthy is the important place Weber always assigned to 
ecological considerations. In his "Grundriss," the chapter on 
ecology occupies about one-fifth of the text. And finally, al- 
though essentially a morphologist, he also gave serious thought 
to fundamental theoretical aspects of systematics as exemplified 
in his article on "Grenzen in der Biologic," in Vol. 5 of Studium 
Generale. Here is a discussion on the possibilities of drawing 
definite boundaries in the course of our research and thinking. 



52 ENTOMOLOGICAL NEWS [Feb., 1957 

After much philosophical argument he concludes, e.g., that 
systematics cannot exist by itself, but that ecological, population, 
behavior, genetic, and especially population-genetic studies must 
go hand in hand with it if we are to discover the reasons for the 
existence or non-existence of boundaries between populations. 
Also, the animal and its environment must be considered as a 
unit, and the variability of the environment compared with the 
variability of the animal. If one does not thus arrive at precise 
definitions and limits, one nevertheless has a truer picture of 
reality. In the study of colonies, social groups, societies, mixed 
populations, and biomes the defining of boundaries is even more 
difficult. As a result, physicists and professional philosophers 
may conclude that biology is an inexact science. Weber's point 
of view was that where sharp boundaries exist we do well to 
define them, but where they do not, where transitions are fluid 
or series continuous, precise delimitation w r ould really make 
biology inexact, would not present a true picture. 

In sum, Hermann Weber contributed a great deal towards our 
present knowledge of the morphology and functional anatomy of 
insects, particularly of the Hemiptera and Anoplura. He was 
also thoroughly conversant with most other aspects of ento- 
mological science so that by means of his text-books, and hih 
monographic reviews on morphology, histology, and develop- 
ment he earned the gratitude of teachers and investigators over 
the world by providing them with such reliable accounts of the 
present state of knowledge. His untimely death is truly a great 
loss to entomology.

Review 

A MORPHOLOGICAL STUDY OF A RELIC DRAGONFLY EPIO- 
PHLEBIA SUPERSTES SELYS. By Syoziro Asahina. The Japan 
Society for the Promotion of Science, Tokyo, 1954. iv +153 
pp., 71 pi. [Maruzen Co. Nihonbashi, Tokyo, $5 (U. S.) ] 

Epiophlebia superstes, a species somewhat zygopteroid and 
anisopteroid but essentially unique, is the subject of a painstaking 
morphological analysis by Syoziro Asahina. Dr. Asahina, along 
with his colleagues, has given us over the past years considerable 
information on the ecology and life history of this interesting 
Japanese species which is attaining thereby the status of one of 
the most completely known Odonata. Turning his attention 
now to more critical matters the author introduces evidence from 
comparative anatomy to facilitate settling the long-standing 
problem of the affinity of Epiophlebia to the recent two great 
suborders. He also succeeds in another aim of his study, 
namely, "to bring forward some rather neglected problems of 
Odonata structure in the light of recent progress on insect 
morphology." 

The gomphine Davidius nanus Selys and the calopterygine 
Mnais strigata Selys are anatomically compared from the view- 
point of homology to both larval and imaginal Epiophlebia su- 
perstes with special reference to sclerites, muscles and several 
internal organs. Comparisons with other Odonata and with 
generalized insects (according to the interpretations of Ferris 
and Snodgrass) add to the significance of this study and to the 
weight of evidence in favor of the author's conclusions. This 
detailed comparative anatomy occupies over three-quarters of 
the text and is supplemented by more than 200 figures. 

Into his review of the chronology of opinion on the systematic 
position of Epiophlebia the author adeptly dovetails the progress 
in understanding of odonate phylogeny. He relates that Selys 
placed Epiophlebia in the Zygoptera ; Needham and Tillyard did 
likewise in their earlier studies but Needham later shifted the 
genus to the Anisoptera whereas Tillyard subsequently placed 
it in Handlirsch's Anisozygoptera, the suborder which flourished 
during the Mesozoic era; Schmidt and Fraser also hold to 



54 ENTOMOLOGICAL NEWS [Feb., 1957 

Anisozygoptera placement. Because of the identical nature of 
the discoidal cells in both pairs of wings. Carpenter is of the 
opinion that a new suborder is probably necessary to accomodate 
this relic species. Although seeming to be in considerable sym- 
pathy with Carpenter's viewpoint, Asahina is of the opinion that 
the Anisozygoptera affinities of Epiophlcbia are quite close based 
on wing venation characters alone. He goes only so far as to 
separate the Epiophlebiidae from the remaining fossil families 
of Tillyard and Eraser's Heterophleboidea by proposing a new 
superfamily, Epiophleboidea ; he considers it advisable to limit 
the fossil Anisozygoptera to the Liassic forms represented by 
the Heterophleboidea and he suggests that the only known 
Tertiary Anisozygoptera, Sieblosiidae of Oligocene times, might 
be a true Zygoptera. 

Evolutionary tendencies of certain morphological features, 
particularly the wings, are discussed with regard to the three 
suborders. Asahina significantly concludes that the super- 
family Epiophleboidea [was] "established from a narrow- 
winged ancestor before the families of Heterophleboidea ap- 
peared and advanced along its own evolutionary passage toward 
the direction of Anisoptery ... it has arrived, in the present 
day, at a state where the body structure, especially the larval 
shape, has attained nearly to a complete Anisopteric stage." 

Dr. Asahina's lucid style has occasional refreshing oriental 
phraseology ; the comparative morphological approach appears 
to be fundamentally sound in the choice of materials ; his conclu- 
sions are not so far-reaching as one might have anticipated but 
are nevertheless well documented. The arrangement of the 
figures is sometimes awkward since they do not always read 
from top to bottom or from left to right and there are one or two 
omissions of figure references on the plates ; although not of the 
usual high oriental standard the figures are wholly sufficient 
for the author's purpose. 

This is a most notable and significant contribution to the 
literature on Odonata and to a broader-based understanding 
of phylogenetic relationship within this group. EDWARD J.

naeschna, Schisuraeschna, Marniaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schisuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under

Variation in Weight, Developmental Rate, and 

Hatchability of Oncopeltus Eggs as a 

Function of the Mother's Age l 

By A. GLENN RICHARDS and MARJORIE O. KOLDERIE, 

Department of Entomology and Economic Zoology, 

University of Minnesota 

It is well known that egg production of various insects may 
be greatly affected by environmental conditions and the past 
history of the mother. But it is commonly assumed that eggs 
laid by females raised and kept under standard conditions will 
be the same irrespective of the age of the female. We uncon- 
sciously assumed this in experiments with the milkweed bug, 
Oncopeltus fasciatus (Dallas), until it became evident that such 
was not strictly true. To be sure, a considerable literature on 
the influence of parental age has accumulated for some groups 
of organisms (see Strong, 1954) but only recently has the phe- 
nomenon been measured in insects (Durrant, 1955 ; Sang, 1956). 

The manner in which many insect species are cultured in the 
laboratory leads to the production of distinct broods rather than 
a population containing all stages of the life cycle. Commonly, 
then, there occur periods when the stage desired is not avail- 
able. As soon as the desired stage becomes available it is used. 
Proceeding in this manner we encountered unexpected trouble. 
The number of hours required for incubation at various tem- 
peratures had previously been satisfactorily taken from the data

of Lin et al. (1954). The data given by Lin et al. were ob- 
tained from eggs collected during the peak of egg laying periods, 
i.e., when the females were two-three weeks post emergnce. 
We have now found that the data of Lin et al. are valid for eggs 
laid during that period but are not valid for eggs laid early or 
late in the fecund stage. Partly to learn how precisely we 
needed to control the mother's age in the sense of restricting egg 
collection to what portion of the fecund period, and partly be- 
cause we needed weight and time data from a fairly large num- 
ber of egg lots for another purpose (Richards, 1957), a syste- 
matic study was made of certain variables. This was repeated 
once ; the general conclusions were the same in the two tests 
and both times fitted with discrepancies previously encountered 
in time of hatching. Only the more extensive set of data will 
be presented. 

For the tests, five dozen teneral adults of Oncopeltus were 
segregated from the stock cultures. The number of each sex 
was not determined but presumably there were about half males 
and half females. This group was held under the same environ- 
mental conditions as they had grown under, i.e., 25 C. and 
60-75% R.H. Eggs will be dropped promiscuously in the 
culture if nothing is present that the female prefers. If small 
rolls of gauze or other open-mesh cloth are added, egg laying 
is stimulated and the eggs are laid in batches inside the roll 
of cloth by insertion of the ovipositor therein. The cloth rolls 
also provide a convenient method for obtaining eggs of known 
age since one has only to remove the roll of gauze after the 
desired interval and open it to extract the eggs. The eggs were 
counted and sorted into weighing bottles using a small soft 
brush. When the group was laying most actively, 400-600 
eggs were used in each lot, but commonly fewer were available, 
and at the beginning and end of the egg laying period only a 
few dozen were available for each lot. The eggs were then 
incubated at 75% R.H. and usually 17 or 25 C. Subse- 
quently, determinations were made of per cent hatching, average 
weights of the newly hatched larvae, and viability of the young 
bugs under standard favorable conditions. 



Ixviii] ENTOMOLOGICAL NEWS 59 

Adult Onco pel 'tits at 25 C. begin mating 4-6 days after reach- 
ing the adult stage, and start laying eggs on the 5th to 8th day. 
At first only a few eggs are laid perhaps only certain females 
begin this early. Thus, for data presented in fig. 1, no eggs 
were obtained on the 5th day, only 78 on the 6th day, 289 on 
the 7th day, but more than 1,500 on the 10th day. Egg produc- 
tion then reached a peak at about 20 days and remained almost 
at the same high level until about 40 days; then it fell off and 
became somewhat erratic. Very late in the test (> 50 days), 
when only the most long-lived were still alive, egg production 
again dropped to a few dozen but the single venerable female 
which lived for 72 days laid 10 eggs shortly before dying. 

As far as longevity of the adult is concerned, we have reason 
to believe that this group lived unusually long. In general, our 
segregated groups seem to have died sooner but we usually dis- 
card groups as soon as significant numbers are seen to have 
died. In one repeat test on longevity, all the females were dead 
after 41-44 days but some males lived to > 50 days. Also, 
less complete data suggest that the peak egg production period 
is not constant from one generation to another. In the gen- 
eration plotted in fig. 1, peak production occurred 18-20 days 
after ecdysis but in other generations it has been sooner (as 
low as 10-12 days). But, however long the groups live and 
whenever the peaks occur, egg production and egg weight are 
low the first few days of egg laying and fall off to low again 
near the end of life. 

As shown in fig. 1, the first several batches of eggs are rela- 
tively light. In this test, the first group had an average weight 
of only 225 micrograms. Average weights then increased to a 
maximum of 280 micrograms in the period when maximum 
numbers of eggs were being produced. This is an increase of 
about 25^o. Subsequent average egg weights then dropped 
but not constantly or with regularity in the period of 25-55 
days of age. Terminal egg lots had very much lower weights 
(about 25% lower than the first lot and 409c lower than the 
maximum value). Averaging all the values together one ob- 
tains an over-all average of 255.0 3.6 micrograms. A pre- 



60 ENTOMOLOGICAL NEWS [March, 1957 

vious test that involved six lots collected at 8-22 days of female 
adult life gave somewhat lower values ranging 226-240 and 
averaging 234 micrograms. It will bear repeating that the 
range of 160-280 micrograms is a range of averages; the range 
of individual egg weights must be greater than this and may be 
very much greater. Even average values from the two halves 
of a single large batch of eggs may vary by several per cent 
(note 33 day group). 

Freshly hatched larvae of course weigh less than the eggs 
from which they develop. But, surprisingly, at below about 
20 C. there is a greater effect of temperature in slowing devel- 
opment than in slowing energy expenditure (Richards, 1957). 
One of the results of this is that whereas larvae from eggs incu- 
bated at 25 C. average 224.8 3.2 micrograms, those from 
eggs incubated at 17 average 203.2 2.7 /*g., and those from 
eggs incubated at 15 C. average only 190.0 /*. Comparing 
values from matched eggs lots, the wet weight losses following 
incubation are 33 micrograms at 25, 53 /xg. at 17, and 83 /xg. 
at 15. Compared to the 20-30 C. range, then, there is 1.6 X 
as much loss at 17, and 2.5 X as much loss at 15. As already 
pointed out elsewhere (Richards, 1957), the weight of eggs is 
not only correlated with their hatchability but seems to be one 
of the factors involved in successful hatching. In other words, 
lighter eggs have less stored food reserves. And since an egg 
contains only a finite amount of food and cannot get more, it 
follows that lighter eggs are less likely to give larvae that hatch 
successfully. It also follows that the variable hatching per- 
centages obtained at and near threshold temperatures may be 
no more than an expression of the variation in egg weights in 
different batches of eggs. In fact, we have data showing that 
only the heaviest eggs can hatch at the threshold temperature 
of 15 C. 

Incidentally, one can calculate the approximate amount of 
energy required for embryonic development from the weight 
losses. Extractions show that almost all of the dry weight loss 
at an incubation temperature of 25 C. is fat ; the water content 
remains constant at 68-707^- From this and well-known aver- 



Ixviii]

age caloric values, one can calculate that only about a tenth of 
a gram calorie is required to complete the development through 
hatching for an Oncopeltus egg at 25 C. This is only enough 
energy to raise the temperature of one drop of water 2 C. or 
about 4 F. !

of 200-500 eggs but fewer eggs were available for the first two and the 
last five points. 

The egg weight value at 53 days must have been erroneously recorded 
to judge from the weight of the larvae obtained; a calculated probable 
value is plotted and joined in by the broken line. The last points of each 
larval curve are queried because of low hatching percentage in these lots. 

Hatchability of the eggs shows differences somewhat parallel- 
ing the weight differences (fig. 2). At 25 C., hatching rises 
from an initial value of 80% to the 92-96% range, and falls 
precipitously for eggs from old females. The differences are 
even greater at 17 where hatchability rises from 38% to nearly 
90% (or even higher if rupture of the egg shell is taken as the 
criterion of hatching). Similar results were obtained in an 
earlier set of determinations. 



62 ENTOMOLOGICAL NEWS | March, 1957 

Similarly, the rate of development is slower for eggs from the 
first and last parts of the fecund period (fig. 4). This quanti- 
tative difference implies a qualitative difference in the eggs that 
can hardly be just a matter of weight and amount of stored 
reserves. What the difference is remains to be determined but 
clearly early and late eggs develop more slowly. [In Drosoph- 
ila inclanogaster, Sang (1956) reports that the opposite is true, 
i.e., the early and late eggs are about 10% faster than those of 
the peak middle period.] 

There is, however, no clear cut difference in the viability of 
larvae that hatch until very late in the egg laying period (fig. 3). 
Larvae from eggs incubated at 25 C. are much more likely to 
grow to maturity when placed at optimum conditions than are 
ones that were incubated at 17. Possible reasons for this are 
being discussed elsewhere (Richards, 1957). 

The dips in the center of the curves in fig. 3 require some 
explanation. Near the end of the experiment M. Q. K. went 
away on vacation leaving these growing larvae to the tender 
ministrations of A. G. R. Her departure came when the larvae 
from 25 incubations of eggs from 38-day females and larvae 
from 17 incubations of eggs from 24-day females were grow- 
ing. The precipitous drop in the 25 curve was due to known 
drowning of the 40-, 42- and 45-day lots, but the drop in the 17 
curve was correlated with infrequent cleaning and renewal of 
seeds rather than accidental mortality. Then, M. Q. K. re- 
turned to tend the final few groups, and survival of 17 lots 
returned to what it had been. 

This otherwise unfortunate episode does suggest an explana- 
tion of a previous discrepancy. Hodson and Al Rawy (1956) 
have reported that Oncopeltus larvae from eggs incubated at 
25 grow satisfactorily whereas ones from eggs incubated at 
17 all die. M. O. K. had not been able to reproduce Al Rawy's 
results but A. G. R. did ! Omitting the facetious language, eggs 
incubated at 17 give weak larvae only a minority of which 
survive under the best care, all of which die under care which 
will suffice for larvae from eggs incubated at 25. [While the 
point was not proven, it seems that the lethal effect is due to

the development of mold on the milkweed seeds. Even at 75% 
R.H. which is rather low for mold growth, seeds must be 
changed and containers cleaned every 2-3 days for survival of 
larvae from eggs incubated at 17 C]

In conclusion, eggs are laid by Oncopcltus females from about 
one week after adult emergence until death. But very early and 
very late in the fecund period fewer eggs are laid, and these 
weigh less, take longer to develop, and give lower hatching 
percentages. These differences are mostly in the 10-20^ range

but in extreme cases may be much greater. It follows that 
minimum variation within a single collection will be obtained 
by using eggs from females of a known standard age (and in 
practice greatest constancy is obtained with Oncopcltus at the 
peak egg production period ) . Conversely, maximum variability 
will be obtained from cultures or populations containing indi- 
viduals of extreme ages plus ones in the peak production period. 
However, as Durrant (1955) points out, quantitative values 
vary from one generation to the next, and less variability may 
be encountered in summing data from different generations if 
a selected sampling procedure is used instead of restricting data 
to the progeny of mothers of a particular age. 

All the data presented in the present paper deal with constant 
temperatures in incubator cabinets. This is satisfactory for 
showing physiological differences but we have reason to know 
that Oncopcltus has considerably narrower tolerance range un- 
der constant temperature conditions than under varying tem- 
peratures whose weighted average equals the constant tempera- 
ture. But this is another story on which we are still working.

Bamboosiella nov. gen. (Phlaeothripidae, Tubuli- 

fera) from India 

By T. N. ANANTHAKRISHNAN, Lecturer in Zoology, 
Loyola College, Madras (S. India) 

Genus BAMBOOSIELLA nov. 

Antenna 8-segmented, slender as in Liothrips; joint 3 emar- 
ginated within, 8 slightly narrowed at base, but not constricted, 
joint 1 narrowed towards apex; sense-cones rather long and 
fine, though on 3 and 4 not setiform. Head elongate, slightly 
narrowed towards base, widest across eyes, cheeks with a few 
weak spines especially in posterior third, as in Hoplandrothrips. 
Mouth-cone short, rounded, maxillary stylets confined to mouth- 
cone, very short, fine. Eyes large, oval ; anterior ocellus on a 
slight elevation but not surpassing interantennal projection. 
Postocular setae long, knobbed, longer in the male. Prothorax 
much broader than head, heavy in the male, with black internal 
middle ridge. Bristles long, all knobbed, inner anteromarginals 
vestigial ; epimerals single. Pterothorax tapering from the mid- 
dle towards apex. 

Legs slender, but forefemora of female distinctly, of male 
strongly enlarged, foretibiae unarmed, foretarsi of both sexes 
with tooth, stouter in the male. Wings narrowed towards mid- 
dle, but from middle to apex little widened, with up to 7 double- 
fringe cilia. Tube short, conical, anal setae long, longer than 
tube, dark. 

Bristle 2 of segment IX of male stouter, much shorter than 
bristle 1, though only spine-like. Bristles on IX (female) long, 
pointed nearly as long as tube. 

Genotype Bamboosiella bicoloripes sp. nov. 

Dr. Priesner, who has kindly examined the specimens, informs 
me that this genus has very close resemblance to Adraneothrips 
Hood and Hoplandrothrips Hood. Adraneothrips differs from 
this genus in the smaller eyes, shorter prothorax, forefemora not 
or scarcely enlarged and cheeks unarmed. Hoplandrothrips has 



66 ENTOMOLOGICAL NEWS [March, 1957 

long, closely approximated maxillary stylets (very short in 
Bamboosiella) and forefemora of male with one or two apical 
teeth. Similarly the genera Apelaunothrips Karny, Phyllado- 
thrips Priesner and Mesothrips Zimmerman, also show affinities, 
though much less than Adrancothrips and Hoplandrotlirips. 
Apelaunothrips has similar coloration, but differs in the band- 
shaped maxillary stylets, short cephalic production, thin fore- 
legs, unarmed tarsi and reticulate ocellar region. Phyllado- 
thrips on the other hand has short head, no double fringe, fore- 
tarsi of female and cheeks unarmed; Mesothrips also has head 
constricted at base, but antennae are thicker, joint 3 shorter 
and strongly conical, more strongly sclerotised in general. 

I wish to express my sincere gratitude to Dr. Priesner of 
Egypt for kindly examining the specimens and for his invaluable 
advice and suggestions.

Insects Reared and Collected from the Pond Snail, 
Lymnaea palustris Miill., at London, Ontario 

By W. W. JUDD, Department of Zoology, University of 
Western Ontario, London, Ontario 

In London, Ontario there is a small cat-tail marsh located at 
the south-east corner of Adelaide and Cheapside Streets, well 
within the built-up area of the city. On May 20, 1955 the 
marsh was dried up to the extent that there was no standing 
water in it and only damp mud formed its floor. On that day 
a large population of the pond snail, Lymnaea palustris Miill., 
was found on the mud. Most of the snails were crowded into 
the damper, shaded hollows while some were generally scattered 
over the mud. None of the snails were moving and each snail 
was withdrawn into the upper portions of the spiral of its shell 
so that no parts of the body could be seen. By cracking open 
the shells it was found that some of the snails were alive, while 
others were dead with the body flaccid and in various stages of 
decay. The living snails were found to be harbouring no para- 
sites or predators, but several of the dead snails contained wrig- 
gling maggots. During the next two weeks collections of the 
snails were made in the marsh and insects were collected or 
reared from them, as related in the following account. All 
specimens are deposited in the collections of the Department of 
Zoology, University of Western Ontario except a few retained 
in the United States National Museum (U.S.N.M.), as noted. 

COLLECTIONS 

1. May 20 One dipterous larva, collected from a snail, 
pupated and from the puparium there emerged on June 7 four 
wasps, Aphaereta auripes (Prov.) (Braconidae). 

2. May 25 One beetle, Glischrochilus quadrisignatus (Say) 
(Nitidulidae) was found in a shell. 

3. May 27 Two Glischrochilus quadrisignatus were found 
among shells in a hollow in the mud. Two rove-beetles, Ale- 



70 ENTOMOLOGICAL NEWS [March, 1957 

ochara sp. and Philonthus sp., were found moving actively 
about in two shells. One wasp, Aphaereta auripes, was col- 
lected as it emerged from the mouth of a shell. 

4. June 1 Six rove-beetles of the subfamily Omaliinae 
(Omalium? sp.) were collected from shells. 

5. June 2 Eighty-five intact shells were collected and placed 
in two jars and adult insects emerging from them were col- 
lected and the dates of their emergence were recorded, as fol- 
lows : June 11 1 Athyroglossa? sp. (Ephydridae) ; June 12 
1 Athyroglossa? sp., 2 Sarcophaga sinuata Mg. (Sarcophagi- 
dae) ; June 13 1 Sarcophaga melampyga Aid., 1 Sarcophaga 
sp. ; June 17 1 Pherbellia justifies (Macq.) (Sciomyzidae), 1 
Pherbellia nana (Fall.), 1 Phygadeuonl sp. (Ichneumonidae), 
10 Aphaereta auripes (Prov.) ; June 18 1 Pherbellia justifies 
(Macq.) ; July 3 1 Muscina stabulans (Fall.) (Anthomyiidae), 
1 Chlacnius sericeus Forst. (Carabidae) ; Aug. 5 1 Muscina 
stabulans (Fall.). 

DISCUSSION OF COLLECTIONS 

Coleoptera 

The ground beetle, Chlacnius sericeus Forst., was in its 
teneral condition when it appeared, so it must have emerged 
from a pupa formed in the snail shell. This species is recorded 
by Blatchley (1910) as being "common about the margins of 
ponds, lakes and streams." Carabid beetles are known to be 
predaceous upon snails (Boettger, 1934, 1935, Ingram, 1946 
and SchaefTer, 1931). The most prevalent beetles in the col- 
lections were the staphylinid beetles of the genera Ale ochara, 
Omalium?, and Philonthus. When the shells were picked up 
these beetles emerged rapidly from the mouth of the shell and 
attempted to escape to cover. The three Glischrochilus quad- 
risignatus were found in or by the shells. Parsons (1943) 
records that this species breeds in fleshy fungi and that other 
nitidulid beetles breed in carrion and are predaceous on insects. 



Ixviii] ENTOMOLOGICAL NEWS 71 

Hymenoptera 

Muesebeck et al. (1951) list several species of calyptrate flies 
as hosts of Aphaereta auripes. The wasps that appeared on 
June 7 emerged from a puparium and those that emerged on 
June 17 were doubtless parasites of puparia in the shells col- 
lected on June 2. The 15 specimens are deposited in the 
U.S.N.M. Muesebeck ct al. (1951) record that wasps of the 
genus Phygadeuon are parasites of muscoid flies. It is likely 
that the ichneumonid wasp that emerged on June 17 was a 
parasite on one of the flies predaceous on the snails. 

Diptera 

Two ephydrid flies, Athyroglossat sp., were the first flies to 
emerge from the snails collected on June 2. The two specimens 
are deposited in the U.S.N.M. One specimen of the non-biting 
stable-fly, Muscina stabulans, emerged on July 3 and the second 
was found in the jar on August 5 when the collection of shells 
was discarded. At least two species of Sarcophaga (melampyga 
and sinuata) were reared from the snails. Berg (1953) re- 
ports that flies of the families Ephydridae, Anthomyiidae and 
Sarcophagidae have been reared from snails. Of the three 
specimens of Pherbellia that emerged from snails, one of P. 
juscipes is deposited in the U.S.N.M. Berg (1953) records 
that flies in several genera of Sciomyzidae are predators of snails 
but does not include P. nana or P. fuscipes.

A New Species in the Genus Arachnoproctonus 

(Hymenoptera: Psammocharidae) with 

Photomicrographs of the Genitalia 

and Subgenital Plate 

By R. R. DREISBACH, Midland, Michigan 

Until the writer's description of Arachnoproctonus occiden- 
talis (ref.), the species A. relativus (Fox) was the only species 
known in this genus which had hair bands on the abdominal 
ventral segments in the male, very similar to those in the genus 
Anopolius. In working on a lot from the American Museum, 
another specimen with hair bands on the fourth and fifth ven- 
trites turned up which had a distinctly different subgenital plate 
than either of the other two, and also with other differences. 
This is described below as a new species. 

Arachnoproctonus variegatus n. sp. 

Holotype male : Completely black, except for the apex of the 
mandibles which are reddish, rather long black hair on the 
vertex, shorter and thinner on clypeus, pronotum, sides of thorax 
and propodeum ; heavy hair brushes on the ventral parts of the 



Ixviii] ENTOMOLOGICAL NEWS 73 

fourth and fifth abdominal sternites, these bands over whole 
length of segments, and hair of same length on each ; when seen 
from the side, nearest of posterior ocelli just barely visible and 
the front below anterior ocellus barely raised above the eyes, 
clypeus almost flat but slightly bowed in the middle, practically 
no posterior orbits ; when seen from the front, the vertex slop- 
ing slightly above the eyes with a slight mound, which contains 
the ocelli, the head width almost equal to the length (0.88) ; 
interocular distance equal to 0.63 X transfacial distance at great- 
est eye width ; vertex width equal to the interocular at the 
clypeus; clypeus twice as wide as its length; posterior ocelli 
slightly greater distance apart than their distance to the eyes 
(16:12) ; ratios of the first four and last two joints of the an- 
tennae are as 25:8:20:25:19:19. Thus it is seen that the first 
and fourth joints are slightly longer than the third ; the third, 
fourth, fifth and sixth joints with ventral surface flattened 
slightly; the pronotum rises in a smooth curve from the neck 
to the dorsal surface, posterior edge slightly triangular and 
curved ; propodeum with short upright hair on dorsal border 
and covered with whitish, very short, almost appressed hairs on 
posterior edge, this is the only silvery hair on the body ; the 
third intercubital vein slopes backward, is slightly wavy but 
almost straight ; the first intercubital vein is strongly arched 
inward, that is convex ; second cell is longer on the cubitus than 
on the marginal vein; second and third cubital veins are only 
about 3 X their width apart on the marginal vein ; the length 
of the two cells on the cubitus almost equal ; basal vein inter- 
stitial with the transverse in the forewings, and in the rear 
wings the cubitus and the discoidal are also interstitial ; the 
wings are very dark colored, more so at the apex ; the abdomen 
increases in width slightly from the base to the middle of the 
second tergite and then decreases to apex of abdomen ; the first 
tergite on the apical half covered with fairly long hair ; legs are 
fairly well spined as is usual with the genus ; ratios of the joints 
of the posterior legs starting with the femur are as 90 : 1 1 5 : 90 : 
45:27:22:28. The longer spur of the posterior legs is equal to 
0.7 the length of its metatarsal joint.

Notes on a Stictia New to the United States 
(Hymenoptera : Sphecidae: Bembicini) 

By HOWARD E. EVANS, Cornell University, Ithaca, N. Y. 

The genus Stictia includes some of our largest and most 
showy digger wasps. Only one species, the common "horse 
guard," S. Carolina (Fabr.), is truly a member of the Nearctic 
fauna. One other species, the Neotropical 5". signata (L.) has 
been taken in southern Florida and in southern California. It 
is now possible to add a third species, 6". vivida (Handl.), to 
the list of species known to occur in the United States. Hand- 
lirsch (1890, Akad. Wiss. Wien, Math.-Nat. Kl. Sitzber., 99: 
25-26) described this species from one female from "Mexico" 
and another female without locality data. Parker (1929, U. S. 
Nat. Mus. Proc., v. 75, art. 5, p. 35) recorded seven females 
from Alta Mira, Tamaulipas, Mexico. These are the only pub- 
lished records on this species, and the male has remained 
unknown. 

From June 22 to June 28, 1956, Eric G. Matthews and myself 
collected insects in Cameron Co., Texas. Most of our time was 
spent along the shores of Laguna Madre about five miles west 
of Port Isabel. In this locality a great many Hymenoptera 
were taken on the flowers of black mangrove, Avicennia nitida 
Jacq., including four male Stictia vivida. We also discovered 
two female vivida nesting on the beach at Boca Chica, several 
miles south and east of Port Isabel. The nests were situated 
in rolling but fairly hard-packed sand well back from, but facing, 
the Gulf shore. The nests were of simple structure, with a 
burrow 60-68 cm long leading to a cell about 2 X 5 cm in size. 
Both nests contained fairly large larvae plus a few horseflies, 
Tabanus texanus Hine [det. L. L. Pechumanj. The females 
carried the flies in the usual manner of Bembicini and always 
closed the nest upon leaving. 

Thus Stictia vivida appears to be well established in extreme 
southern Texas. I also collected the species on June 19, 1951, 
at Tecolutla, Vera Cruz, Mexico. In this locality nine females 



Ixviii] ENTOMOLOGICAL NEWS 77 

were taken in sand dunes immediately behind the beach. These 
new records, along with Parker's record from coastal Tamau- 
lipas, indicate that the species ranges along the Gulf shore for 
at least 400 miles. I have collected Stictia at several inland 
localities in Mexico, but have never taken vivid a away from 
the sea beach. 

Since the male has not previously been described, a few notes 
on its recognition may be in order. In both Handlirsch's and 
Parker's papers, the males key directly to dives (Handl.), a 
common inland Mexican species. They bear a close resemblance 
to dives, but differ in the following characters : labrum narrowly 
bordered with black, but with little or no black medially ; yellow 
on the scutellum narrowly interrupted medially ; penultimate 
sternite with moderately dense, short, suberect setae and with 
the specialized median elevation located at the extrem base and 
not conspicuous. The male vivida closely resembles the female 
in color pattern, differing chiefly in having less yellow on the 
mesopleura, in having the apical abdominal tergite marked with 
yellow, and in having the legs much more extensively marked 
with yellow. 



More About Membracidae at Lights 

By S. W. FROST, Pennsylvania State University 

In 1955 l the writer reported large numbers of Membracidae 
taken at lights and noted that previously most entomologists 
considered they were not strongly attracted to light. During 
1956, a trap operated in Centre County, Pennsylvania, attracted 
even larger numbers of these insects. This trap was equipped 
with a 60-watt tungsten filament lamp and was placed in a 
dense oak woodlot. Several nights during July unprecedented 
numbers of Membracidae were caught. Collections on the 

!Ent. News, 66(3) : 63-64, 1955.

nights of July 1 and 6 were selected for analysis. The insects 
were caught in a quart jar, containing kerosene, at the bottom 
of the trap. The Membracidae were separated from the other 
insects, dried and weighed. Immediately a sample was taken 
and the species of treehoppers determined as follows.

It is more evident than previously published that Membraci- 
dae, especially those of the Genera Atymna, Cyrtolobus and 
Ophiderma, are attracted in large numbers when lights are close 
to the infestations. It is also evident that the males respond 
more freely than the females.

Notes and News in Entomology 

Under this heading we present, from time to time, notes, news, and 
comments. Contributions from readers are earnestly solicited and will 
be acknowledged when used. 

Pacific Science Congress. The Ninth Pacific Science Con- 
gress will be held at Bangkok, Thailand, 18 Nov. to 9 Dec., 
1957 (including post-sessional tours). Plans for the entomol- 
ogy section include sessions on problems in Pacific entomology ; 
zoogeography of Pacific insects ; fauna and ecology of Thailand 
(with Zoology) ; use of insecticides, their merits and hazards, 
and insects of medical importance (both with Public Health 
section) ; biological control of insects and weeds; insect pests 
of rice ; coconut pests ; ecology and control of the giant African 
snail ; and quarantine. Also, participation in UNESCO sym- 
posium on climate, vegetation and land utilization in the humid 
tropics, and participation, with zoology and botany, in sympo- 
sium on bibliographic problems in the Pacific. For the latter, 
the undersigned would like to receive information regarding 
bibliographies in preparation, or in existence, which include 
Pacific insects or relate to Pacific entomology, or suggestions 
for needs in this line. 

It is hoped that as many entomologists as possible may try 
to get to the Congress, and that papers on the above, or addi- 
tional subjects, may be submitted. Correspondence may be 
addressed to the undersigned, chairman of the Standing Com- 
mittee on Pacific Entomology, at Bishop Museum, Honolulu 17.

Fire at the Budapest Museum. During the revolution in 
Hungary in late 1956 part of the Hungarian National Museum 
in Budapest was burned. According to Mrs. J. J. H. Szent- 
Ivany who was working at the museum at the time, the Acarina, 
Orthoptera, neuropteroid and Diptera (except acalyptrates) col- 
lections were entirely destroyed (including a few thousand Dip- 
tera types), and the very important Horvath collection of Het- 
eroptera was partly destroyed, but the Coleoptera and Lepidop- 
tera collections remained safe, with only slight damage. Mrs.

Szent-Ivany escaped to Vienna with her daughter near the end 
of the year, and both are joining Dr. Szent-Ivany in New

New Book on Tropical American Butterflies. The Ameri- 
can Museum of Natural History is about to publish "BUTTER- 
FLIES OF THE AMERICAN TROPICS The Genus Anaea (Lepi- 
doptera Nymphalidae) a study of the species heretofore 
included in the genera Anaea, Caoenophlebia, Hypna, Poly- 
grapha, Protogonius, Sidcronc, and Zaretis" by William 
Phillips Comstock. 

From advance specimen pages sent out it is evident that this 
will be a large and beautiful volume. The page size, trimmed, 
is 9% x 13 inches, and there will be xvi + 276 pages and 30 
full-page color plates. Dr. A. B. Klotz has spoken very highly 
of the scientific value of this work and also points out that . . . 
"because of its superb beauty of illustration and excellence of 
design, [it] is destined to have the strongest appeal to biblio- 
philes the world over, as well as to everyone genuinely inter- 
ested in natural history. I am afraid that we in the United 
States have lagged behind in the production of such books. 
This one, happily combining great intrinsic scientific worth 
with illustrative artistry of the highest calibre, will do much 
to redeem us." 

Because of the great costs of the 30 color plates it is necessary 
for the American Museum to obtain in advance an indication 
of the demand for such a book, as well as for a series of such 
books on butterflies and on other groups that is under consid- 
eration. The pre-publication price is $20.00 per copy. After 
publication the price will be $25.00. Orders should be sent to: 
The American Museum of Natural History, Central Park West 
at 79th Street, New York 24, N. Y. If British sterling is more 
convenient, send orders direct to the printer, W. S. Cowell, 
Ltd., Butter Market, Ipswich, Suffolk, England.

Reviews 

Ross, HERBERT H. 1956. Evolution and Classification of the 
Mountain Caddisflies. University of Illinois Press, Urbana. 
vi + 213 pp. Price: $6.00. 

Though this volume treats, in detail, only the families Philo- 
potamidae, Rhyacophilidae and Glossosomatidae, it is in reality 
far broader in its scope than the title would indicate. 

In the introduction Dr. Ross treats of such concepts as "liv- 
ing fossils," "primitive, generalized and specialized" and "dis- 
persal." These concepts, basic to any discussion of phylogeny, 
are briefly and lucidly denned. This is followed by an excellent 
discussion of the evolution and origin of the caddisflies as a 
whole. The main part of the book consists of a detailed treat- 
ment of each of the above mentioned families. For each family 
the evolution and dispersal of the genera and species is given 
followed by a systematic treatment of the family with keys to 
genera and species. 

The last major section is concerned with the dispersal in 
geologic time of the above three families. This is a difficult 
and, to a large extent, speculative subject involving as it does 
the superimposition of the aforementioned evolutionary and dis- 
persal data upon the geologic and ecologic history of the earth. 
This task is very ably handled here and this section could serve 
as a model for this type of study. The volume is well worth 
reading by any student of systematics and evolution, regardless 
of his particular field of study. SELWYN S. ROBACK. 

SYSTEMATICS OF THE SUBORDER TUBULIFERA (THYSANOP- 
TERA) IN CALIFORNIA. By H. Edwin Cott. University of 
California Publications in Entomology, Vol. 13. (University 



82 ENTOMOLOGICAL NEWS [March, 1957 

of California Press, Berkeley and Los Angeles.) 216 pp., 4 pis. 
1956. Price: $3. 50. 

This is the first analytical work of size on a thrips fauna to 
appear in America since Hinds' monograph in 1902. Although 
limited to California, which is relatively depauperate in repre- 
sentatives of Tubulifera as compared to the eastern and tropical 
regions of North America, Cott's work is of wide significance 
because it summarizes the taxonomic criteria and methods com- 
monly used in the study of the suborder. Furthermore, because 
intergrading species between Haplothrips and Leptothrips and 
between Liothrips and Rhynchothrips flourish in California, 
Cott is able to bring meaningful attention to the problem of 
delimiting these extensively distributed genera. 

In all, Cott treats 29 genera and 60 species, of which 12 of 
the species are new. His classification is a conservative one 
following closely the system proposed in 1927 by Priesner. 
Each genus is redefined and is discussed with particular refer- 
ence to affinities and taxonomic status. The species are de- 
scribed in detail and type localities, hosts, distribution, and 
material studied are given. The keys appear to be workable. 

Of general interest to entomologists is Cott's break with 
tradition in referring to the immature stages of thrips as nymphs 
and pseudopupae rather than as larvae and pupae. His argu- 
ment for this nomenclature is that it is in keeping with the 
nomenclature used for other insects having paurometabolous 
development. 

This careful study provides the specialist with much new 
information on a heretofore little known fauna and, of equal 
importance, it provides interested entomologists with the first 
modern American guide to a portion of the Tubulifera. LEWIS

Ixviii] ENTOMOLOGICAL NEWS 83 

The first edition of this textbook was reviewed in ENTOMO- 
LOGICAL NEWS for May, 1949 (Vol. 60: 139). This second 
edition maintains all the virtues described in that review, and 
we may affirm in 1957 that this is still the only American text- 
book that will provide the student with an introduction to the 
science of entomology as it exists to-day. Covering, as it does, 
so wide a field in only 500-odd pages, it necessarily concerns 
itself with fundamentals to the exclusion of minor detail. Each 
chapter, whether it deals with the history of the subject, ex- 
ternal or internal anatomy, physiology, life cycles, the orders 
of insects, geological history, ecology, or control, is very skill- 
fully written so as to present the basic facts concisely, and in 
simple language. In spite of treating the subject from such 
a broad standpoint, the study of the insect orders is by no means 
slighted. Under each order there are keys to the principal fami- 
lies with line drawings illustrating all the characters used in 
these keys, and there are the customary habitus pictures of rep- 
resentative forms, and descriptive text. 

The entire book has been re-set in a different style of type 
and with more pleasing headings. A great improvement in 
general appearance has also resulted from re-drawing and mak- 
ing new engravings of most of the numerous anatomical illus- 
trations. The convenience of having each anatomical part 
labelled directly with its name instead of with a symbol will 
also be appreciated. R. G. SCHMIEDER.

JAMES SPEED ROGERS 

1891-1955 



ENTOMOLOGICAL NEWS 



VOL. LXVIII APRIL, 1957 No. 4 

James Speed Rogers, 1891-1955 

With the passing of Doctor James Speed Rogers, at the rela- 
tively early age of 63, the world has lost the leading student of 
the biology and ecology of the Tipulidae, largest family in the 
order Diptera (over 11,000 species). Dr. Roger's longtime 
associate, Dr. Theodore H. Hubbell, present Director of the 
Museum of Zoology at the University of Michigan, has pre- 
pared a detailed account of his life and work. 1 In the brief 
space available I am able to note only a few points of general 
and personal interest in the career of this outstanding worker 
and dear personal friend. 

Dr. Rogers, affectionately known to his close friends by his 
middle name of "Speed," was born in Dayton, Indiana, Novem- 
ber 4, 1891, son of the Reverend Mr. Henry Martyn Rogers 
and Alma Goodloe (Smith) Rogers. He died suddenly and 
unexpectedly of a heart ailment at Ann Arbor, Michigan, on 
May 17, 1955. Following his high school days, he briefly 
attended Hanover College, Hanover, Indiana, later going to the 
University of Michigan from whence he received successively 
the degrees of A.B. (1915), A.M. (1916), and Ph.D. (1930). 
From 1919 to 1922 he was on the staff of Grinnell College, 
Grinnell, Iowa, which he left to become Professor of Biology at 
the University of Florida, from 1922 to 1946. In 1946 he was 
called to his Alma Mater to become Professor of Zoology and 
Director of the Museum of Zoology, a position that he held to 
the moment of his decease. On April 18, 1918, he was married 
to Miss Irene Russell, whom he had known in his college days,

and who survives him, together with his two children, Dr. 
James Speed Rogers and Mrs. Irene Russell Howard. At the 
time of his passing he was a member of several of the leading 
entomological societies. 

Although his studies on the biology of crane-flies occupied 
virtually all of his research time, he prepared, with Drs. Hubbell 
and Byers, one of the outstanding university texts, "Man and 
the Biological World." 2 His published papers on the Tipulidae, 
18 in number, have been listed in the Bibliography prepared by 
Dr. Hubbell. To this record one further article that had been 
omitted inadvertently, should be added. 3 While all of the 
papers that he wrote on the biology and ecology of the Tipulidae 
are important, three are so outstanding that they must always 
rank as models in their treatment of the subjects. 4 

At the time of his passing, Dr. Rogers had some further 
papers in various stages of preparation, one of which (on 
Lipsothrix sylvia} was completed by his student, Dr. George 
W. Byers. Others are sufficiently advanced that they may be 
reviewed and eventually published. However, as is so often the 
case with outstanding workers who are overwhelmed with other 
duties, the great mass of his observations remains unpublished, 
and very many, perhaps the great majority, of his numerous 
observations passed with him. There remain, however, care- 
fully prepared field notes, voluminous records, and an unparal- 
leled collection of the immature stages in the family, which will 
provide the basis for future work on the subject.

Additional to his great work on the immature stages of crane- 
flies, Dr. Rogers later in his career became intensely interested 
in problems of subspeciation, clinal distribution, and comparable 
aspects, and in his attempts to solve some of the problems that 
are found here, built up a vast collection of the adult flies in this 
group. He once told me that he wished he could secure 10,000 
specimens of every species. Dr. Hubbell estimates that the col- 
lection may include 100,000 pinned specimens of the adult flies, 
with between 400,000 and 1,000,000 still in papers, accompanied 
by more than 7,000 microscope slides showing the critical struc- 
tures needed in classification, particularly the wings and male 
genitalia. The vast bulk of this unparalleled collection is from 
the United States and Canada and many, if not the greatest 
proportion thereof, were collected by him while on his various 
field excursions. A fuller account of this outstanding work is 
included in Dr. Hubbell's paper. 

Very early in our careers, Speed and I were attracted to one 
another through our mutual interest in the crane-flies, and it 
was soon decided that he would devote his principal energies 
to the biology and ecology, while I hoped to give more and more 
of my time to a taxonomic study of the group. To further this 
arrangement, I at once turned over to Speed my extensive col- 
lections of the immature stages of crane-flies that had formed the 
basis of my report "The crane-flies of New York, II, Biology 
and Phylogeny." Even at that early period, Speed once wrote 
that "he hoped that some day the two of us might perhaps live 
sufficiently long to make this group the best known of all the 
families of the Diptera." 

Because of our wide geographical separation, we had very 
few opportunities to meet or to enjoy joint field trips. Two 
outstanding meetings may be mentioned. In June 1921 we 
enjoyed a two- weeks' collecting trip across southern Indiana, 
beginning at Hanover, the family home, continuing westward 
across the southern counties to New Harmony on the Wabash 
River. This trip was rich with happy experiences for both of 
us. It was at New Harmony that we had the good fortune to 
locate many hitherto unknown data concerning Thomas Say, 



88 ENTOMOLOGICAL NEWS [April, 1957 

which were later used by Weiss and Ziegler in their classic 
account of the subject. 5 In July 1928, prior to the meetings of 
the Fourth International Congress of Entomology at Ithaca, 
N. Y., the late Dr. Fred W. Edwards of London, England, with 
Mrs. Edwards, visited us at Amherst for one week, and Speed 
came from Gainesville, Florida, for the occasion. Most enjoy- 
able and profitable field excursions during the days, and happy 
evenings spent around a table pinning and papering the col- 
lected materials, provided all of us with unforgettable memories. 
During that time a vast range of subjects relating to the Tipu- 
lidae came under review, adding to a better understanding and 
appreciation for all of us. 

Speed Rogers developed various students of crane-fly biology 
and ecology, both at Florida and later at Michigan. The more 
outstanding of such students include Drs. R. E. Bellamy, George 
W. Byers, Dennis Hynes, and Benjamin Foote. It is expected 
and believed that these students will carry the Roger's tradition, 
as it concerns the Tipulidae, far into the future. To persons 
such as myself, who have been privileged to a long association 
with Speed Rogers, a simple expression of appreciation and 
thanks seems quite inadequate. It is certain that the lives of 
all of us were vastly enriched by this association and by the 
priceless friendship of a great and kindly man. 

The accompanying portrait of Dr. Rogers was taken by Dr. 
George W. Byers, in the Museum of Zoology at Ann Arbor, 
within a few days of his death.

Redescriptions of Ewing's Oribatid Mites, I Fam- 
ilies Zetorchestidae, Hermanniellidae (Acarina: 

Oribatei) * 

By TYLER A. WOOLLEY, Department of Zoology, Colorado 
A. & M. College, Fort Collins, Colorado 

Two summers ago the writer received a series of pencil draw- 
ings of Ewing's type oribatids from Dr. E. W. Baker, Curator 
of Acarina at the U. S. National Museum. Dr. Baker sug- 
gested that the recipient finish the drawings and redescribe the 
mites for publication. Following this suggestion the redescrip- 
tions were begun. 

Originally the author planned to incorporate these drawings 
and redescriptions in reviews or revisions of the various families 
involved. This was done in a few minor instances. Subse- 
quently, however, the writer became convinced that such delay 
would defer the publication of these drawings for too long a 
time ; that early publication of the redescriptions and drawings 
would be an asset to anyone whose research might require exact 
knowledge of Ewing's species. 

The writer, therefore, proposes to submit a series of articles 
on Ewing's type oribatids for publication. The redescriptions 
and discussions of these forms will be presented in a somewhat 
cursory fashion, without attempts to do much more than iden- 
tify and illustrate the mites. It may be possible later to incor- 
porate these data into more effective arrangements, such as 
reviews or revisions of families or genera. 

The author has attempted to utilize the same general sequence 
of description as employed by Ewing. Some statements of the 
latter are incorporated in the redescriptions in more modern 
terms by the use of current acarological terminology. Discrep- 
ancies or minor variations in the descriptions are indicated by 
parenthetical means. 

It should be noted that while the current article is first in 
the numerical designation of the series, several redescriptions

Foundation. 



90 ENTOMOLOGICAL NEWS [April, 1957 

preceded this writing (Woolley & Higgins, 1955; Woolley, 
1955; Woolley, 1956). 

The writer expresses his sincere appreciation to Dr. E. W. 
Baker for the drawings of Ewing's type oribatids, recognition 
of which is made by initials on the finished plates. 

FAMILY ZETORCHESTIDAE MICHAEL, 1898 

According to Baker and Wharton (1952) the principal char- 
acteristic of the family Zetorchestidae is the pronounced devel- 
opment of the fourth pair of legs, which enables these mites to 
jump. Grandjean (1951) cites this feature and other details 
in his descriptions of the family and its genera Zctorchestes, 
Saxicolestes, Diorchestes, Belorchestes and Litholcstes. 

The two species known by Ewing were Zctorchestes micro- 
nychus Berlese, 1888 and Zetorchestes equestris Berlese, 1908. 
Ewing (1909b) cites the collection of a specimen of the former 
species by C. R. Crosby at Columbia, Missouri, but no date is 
indicated. Dr. Baker's drawing is of the latter species, which 
was collected by C. R. Crosby in trash at Columbia, Missouri. 
Its description follows. 

Zetorchestes equestris Berlese, 1908. (Figs. 1, 2) 

Color black ; rostrum blunt ; rostral hairs stout, simple, curved 
at tips, inserted in short peduncles. Lamellae roughened plates 
at sides of propodosoma, divided by a suture mid-way between 
insertion of lamellar hair and base of pseudostigmata. Lamellar 
hairs long, simple, incurved, extended beyond anterior tip of 
rostrum, twice as long as rostral hairs, narrower. Surface of 
propodosoma with small knobs. Interlamellar hairs fine, de- 
curved, inserted half their lengths from medial edges of lamellae 
at level of pseudostigmata, about four times their lengths apart. 
A glandular area posterior and medial to insertions of inter- 
lamellar hairs. Pseudostigmata large, cup-like, contiguous with 
posterior width of lamellae. Pseudostigmatic organ clavate, 
about twice as long as interlamellar hairs, setose at tips. 

Hysterosoma almost circular in outline (specimen broken on 
right side), with a prominent posterior tubercle. Seven pairs

of prominent, simple bristles on dorsum (Fig. 1). Two pairs of 
glandular fissures, one pair antero-laterad of c:2 bristles (an- 
tero-lateral corner) ; second pair posterior and laterad of large 
tubercle at distal end of hysterosoma.

Specimen broken on right side by pressure of coverslip. 
FIG. 2. Zctorchestes equestris Berlese, 1908, from the ventral aspect. 

Venter with a prominent camerostome ; chelicerae stout. 
Pedunculate insertions of lamellar hairs visible antero-laterad 
of camerostome. 

Surface of ventral plate covered with small knobs. Genital 
opening nearly circular, close to anal opening and about three- 
fourths as long as latter. Anal opening broadly triangular ; anal 
plates agape in specimen due to pressure of coverslip. A single 
pair of adanal setae posterior to anal opening. 

Apodemata I curved posteriorly adjacent to camerostome at 
level of base of chelicerae. Tibia of leg I an expanded triangle, 
with long tactile bristle (Fig. 2). Tarsi of leg I ending in a 
single claw, setal arrangement incompletely shown in Fig. 2. 
Apodemata II and III extended mediad, parallel and close to 
each other; insertions of legs II and III close together. Distal 



92 ENTOMOLOGICAL NEWS [April, 1957 

parts of legs II and III incompletely illustrated in original draw- 
ings. Insertions of legs IV at level of middle of genital aper- 
ture. Leg IV modified for jumping; coxa with triangular cap; 
trochanter greatly curved ; genu short, between stout femur and 
distally expanded tibia ; tarsus attenuated, ending in a single 
claw. 

Length 400 /*, width 300 ^. 

DISCUSSION. Ewing (1909) indicates both Zetorchestes mi- 
cronychus and Z. equestris as having been collected in trash by 
C. R. Crosby at Columbia, Missouri. Berlese's original descrip- 
tion of Z. equestris (1908) is rather terse and without an ac- 
companying figure. He cites the location as Columbia, which 
Grandjean (1951) indicates to be in Canada. 

FAMILY HERMANNIELLIDAE GRANDJEAN, 1934 

The distinctive characteristic of this family is a projected 
lateral peduncle on each side of the opisthosoma. This peduncle 
constitutes the opening of an oil gland duct. 

Four varieties of the genus Hermanniella Berlese, 1908, are 
listed by Ewing (1918), two of which are redescribed below as 
separate species. 

Hermanniella robusta Ewing, 1918. (Figs. 3, 4) 

Rostrum depressed, rostral hairs not visible. Dorsum of 
propodosoma with two prominent humps on anterior face, sur- 
face pitted ; an elevated shelf anterior to pseudostigmata ; a 
median trough near hysterosoma, between pseudostigmata. In- 
terlamellar hairs erect, barbed, inserted between pseudostigmata 
on each side of median trough. Pseudostigmata prominent cups 
(Figs. 3, 3 A) ; pseudostigmatic organs erect, with barbed tips. 

Hysterosoma oval in outline (specimen slightly tilted), with 
pitted surface ; with nine pairs of stout, erect hairs, all hairs of 
equal size. Glandular tubercle as in Fig. 3. 

Chelicerae stout, beneath propodosomal prominences (as seen 
in tilted specimen). Apodemata broad plates in anterior part 
of venter, apparently flattened. Setal insertions as shown in 



Ixviii] ENTOMOLOGICAL NEWS 93 

Fig. 4. Genital aperture nearly circular, genital plates oval, 
with four pairs of setal insertions visible; g:2 remote from 
medial margin of plates, other insertions approximating medial 
margin of plates. Anal aperture separated slightly from genital 
opening, broadly oval; anal plates somewhat triangular, with 
two pairs of simple setae near median margin of plates. Two 
adanal setal insertions laterad of anal aperture. 

Insertions of legs I and II in conical sheaths ; coxae of legs 
III and IV expanded distal to insertions. 

Length 800 /x, hysterosoma 642 /A; width (tilted position) 
470 ^ 

H. E. Ewing collected a single specimen from Mary's Peak, 
Oregon. 

Hermanniella occidentalis Ewing, 1918. (Figs. 5, 6) 

Propodosoma broadly triangular, dorsum pitted. Rostrum 
bluntly pointed, rostral hairs short, incurved. Lamellar hairs 
erect, stiff, directed forward, inserted half their lengths from 
and almost directly behind rostral hairs. Posterior part of 
propodosoma elevated and rounded between pseudostigmata. 
Interlamellar hairs nearly twice as long as lamellar hairs, erect, 
slightly outcurved, inserted laterad of rounded summit of propo- 
dosoma, closer to pseudostigmata than to median line. Pseudo- 
stigmata depressed cups, rims of cups continuous with surface 
of propodosoma. Pseudostigmatic organ clavate, setose at tip, 
with darkened center (Fig. 5A). 

Hysterosoma broadly oval, dorsum pitted, with nine pairs of 
strong, erect setae ; median posterior pair of dorsal setae heavier 
than others. Lateral oil gland ducts pedunculate, extended from 
lateral surface between legs III and IV, about mid- way between 
anterior and posterior margins (Fig. 5). 

Camerostome triangular, two setae posterior to chelicerae. 
Apodemata and setal insertions as shown in Fig. 6. Genital 
opening nearly circular, slightly oval ; aperture medial, between 
legs IV ; genital plates with straight medial margins, rounded 
lateral edges, each plate with five setal insertions along medial 
margin, subequally spaced. Anal opening about twice as large 



94 ENTOMOLOGICAL NEWS [April, 1957 

as genital aperture ; anal plates with straight medial margins, 
rounded lateral sides ; each plate with two long setae inserted 
remote from medial margin. Three pairs of adanal setae, two 
pairs near antero-lateral margin of anal aperture (Fig. 6) ; a 
pair adjacent to posterior margin of anal aperture. 

Legs I and II with triangular coxae; coxae of legs III and 
IV expanded; setation of legs as in Fig. 5. 

Length 666 p, hysterosoma 500 ^ ; width 400 p. at tubercles. 

Dr. Ewing collected two specimens under a rotting log on 
the top of Mary's Peak, Oregon. 

DISCUSSION. The original description of Hcrmanniella punc- 
tiilata Berlese, 1908, consists of five words that describe the 
minute pits in the dorsal integument. The description is fol- 
lowed by the measurements (540/x long, 380^ wide) and a 
statement that the species is smaller than H. granulata (650 ^ 
long, 450 /A wide). Van der Hammen (1952) points out that 
the sculpturing of the hysterosoma varies and that some of 
Berlese's measurements are contradictory. 

Ewing (1918) indicates that H. punctulata var. robusta dif- 
fers from Berlese's type in size, but his variety also shows other 
differences than those indicated for the European species. The 
writer is convinced that both of the varieties which Ewing de- 
scribes are separate species. H. robusta Ewing, 1918, differs 
from H. punctulata Berlese, 1908, in the prominent knobs and 
dorsal median trough on the propodosoma (Fig. 3). There is 
an additional distinction in the integumental reticulations, which 
vary in both European and American species. 

Hcrmanniella accident alis Ewing, 1918, is considered a sepa- 
rate species because of the rounded, relatively inornate propodo- 
soma, which lacks knobs and a median groove ; the sunken

pseudostigmata, differences in pseudostigmatic organs ; the pos- 
terior pair of stout hysterosomal bristles ; and the difference in 
setation of the genital covers. 

Possibly Hermanniella subnigra (Ewing), 1909, should be 
considered as a separate species inasmuch as Ewing's descrip- 
tions and illustrations indicate it is in this genus instead of 
Hermannia (Nic.). The writer does not have a drawing or 
specimen of this species for comparison, however, and therefore 
defers exact placement.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schisuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schisuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other ; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo-

Redescriptions of Ewing's Oribatid Mites, II 
Family Carabodidae (Acarina: Oribatei) l 

By TYLER A. WOOLLEY, Department of Zoology, Colorado 
A. & M. College, Fort Collins, Colorado 

This article is the second in a series of redescriptions sug- 
gested by Dr. E. W. Baker, Curator of Acarina at the U. S. 
National Museum. Two of Ewing's type oribatids are de- 
lineated below. 

FAMILY CARABODIDAE WILLMANN, 1931 

Two of the diagnostic features of this family usually comprise 
broad lamellae and highly sculptured integument. According 
to Willmann (1931), and Baker and Wharton (1952) femora 
I and II in these mites exhibit thin stalks and swollen distal 
ends, also. Many of these mites, in addition, possess a cero- 
tegument, which covers the body and sometimes the legs in such 
thickness that details of the propodosoma and hysterosoma are 
obscured. 

Carabodes flavus (Ewing), 1918, nov. comb. (Figs. 1, 2) 

Cotype : Ccpheits flavus Ewing, 1918, p. 86. 

Description: Propodosoma nearly rectangular, about a fourth 
as long as hysterosoma; surface highly sculptured and rough- 
ened due to presence of cerotegument. Rostrum obscured by 
cerotegument of broad lamellae, which extend along the lateral 
length of propodosoma and are broadly joined medially at an-

Foundation.

terior end to form a hood-like structure above the rostrum. 
Lamellar hairs not visible. No translamella. Interlamellar 
hairs not observed. Pseudostigmata cup-like, with deep bowl, 
inserted at latero-posterior aspect of propodosoma in angle 
formed by projecting shoulders of hysterosoma. Pseudostig- 
matic organs clavate with a short, bent pedicel ; projected pos- 
tero-laterad, finely setose at tips. Tectopedia I anterior to 
level of pseudostigmata, closely appressed to propodosoma. 

Hysterosoma broadly oval in outline, with roughened surface 
and slightly scalloped lateral and posterior margins, dorsal cover 
hexagonally reticulate. The roughened surface evidently a 
cerotegument, which stands above the actual body surface and 
obscures some details of the understructure. Beneath this cover 
the integument is pitted with even, round pits. The only hys- 
terosomal setae visible in the type specimen are four, short, 
simple bristles at posterior margin of hysterosoma (Fig. 1). 

Camerostome oval in outline, with two simple bristles poste- 
rior to chelicerae. Apodemata II, III and IV darkly sclerotized 
transverse bars, IV angled slightly posteriorly from anterior 
edge of genital aperture. Genital opening subcircular in out- 
line, slightly smaller than anal opening; each genital cover with 
four setal insertions on medial edge ; g : 1 and g : 2 subequally 
spaced from each other; g:3 and g:4 farther apart. Anal aper- 
ture trapezoidal in outline, anal covers open slightly in type 
specimen : each anal cover with two setae ; a : 1 near middle of 
medial edge, a:2 close to medio-posterior corner of cover. 

Legs as in Figs. 1 and 2. Leg IV does not extend to poste- 
rior margin of hysterosoma. Legs tridactyle, all tarsal claws 
subequal in length. 

Length 785 /*, hysterosoma 556 /A ; width 486 p. 

Ewing (1918) indicates that the specimens were collected 
from the top of Mary's Peak, Oregon and from Corvallis, Ore- 
gon, in both instances beneath logs. He mentions that the type 
is one of the specimens from Corvallis collections and differs 
slightly from the examples from Mary's Peak.

Cepheus subniger (Ewing), 1917, nov. comb. (Figs. 3, 4) 

Cotype : Tegeocranus subniger Ewing, 1917, p. 163. 

Description: Dark brown, almost black. Propodosoma and 
hysterosoma covered with secretion or cerotegument which ob- 
scures details beneath. Rostrum slightly visible between distal 
ends of lamellae ; rostral hairs not visible. Lamellae very large, 
covering lateral aspects of propodosoma from pseudostigmata 
to base of rostrum ; about as wide as length of pseudostigmatic 
organ and apparently covered with secretion. Lamellar and in- 
terlamellar hairs not visible ; no translamella. Pseudostigmata 
cornuate, extended mediad about half the width of a single 
lamella ; rim margin apparently continuous with margin of la- 
mella. Pseudostigmatic organ clavate, slightly recurved, with 
pectinate head and about as long as width of lamellae at level 
of pseudostigmata. Tectopedia I extended forward from level 
of pseudostigmata half the length of lamella, sclerotized dorso- 
medial margins. 

Hysterosoma broader than long, broadly rounded behind ; 
with a few minute hairs dorsally, according to Ewing. A 
pteromorph-like band of secretion between base of leg IV and 
proximal end of lamellae, extended in a shoulder expansion, 
with undulating margins and reticulate surfaces. 

Camerostome attenuated anteriorly, with two ventral setae. 
Setal insertions of ventral plate as in Fig. 4. Apodemata II 
long and narrow, medial ends approximated near mid-line. 
Genital opening between apodemata III and IV, about three- 
fourths as large as anal aperture, two-thirds the length of geni- 
tal covers anterior to anal opening; genital covers nearly rec- 
tangular, wider at level of g:2, with five setal insertions visible 
on medial margin of each cover; g:l, g:2, g:3 and g:4 sub- 
equally spaced on medial margin of each cover; g:5 more 
widely separated from g:4 and close to medio-posterior corner 
of cover. Anal aperture trapezoidal, narrowed anteriorly. No 
anal setae visible. Three pairs of adanal setae, insertions as in 
Fig. 4. 

Legs large; anterior pair extending beyond tip of rostrum 
nearly full length of tarsi ; tibiae of anterior legs without ante- 



Ixviii] ENTOMOLOGICAL NEWS 117 

rior tubercles ; legs IV extending beyond posterior margin of 
hysterosoma; all tarsi with a single, stout, curved claw. 

Length 771 /x (to tip of rostrum), hysterosoma 412 /*.; width 
542 p.. 

Ewing (1917) indicates that this species was collected under 
pieces of old board at Ames, Iowa. 

Discussion: The generic designation of Carabodcs flauus 
(Ewing) is as exact as is presently possible because of the 
cerotegument, which prevents description of other details. This 
species is much larger than known species of Carabodes, but 
possesses three tarsal claws and four pairs of genital setae, 
which are distinctive for the genus. The notations on the co- 
type slide in the writer's possession designate this specimen as 
"Cephcus javus, n. sp." The "1" is missing in the specific name. 
Collection data on this same slide indicate : "Top of Mt. Chinti- 
mini, Or., Sept. 12, '12; by myself. Under rotting log. Bal. 
H. E. Ewing." 

The specific position of Cephens sitbniger (Ewing) is as exact 
as is possible at present because the cerotegument obscures other 
details. The species corresponds in size to other representatives 
of the genus. Its generic placement is based on size, presence 
of single tarsal claws and five pairs of genital setae. Baker and 
Wharton (1952) synonymize Tegeocranus Nic., 1855, the genus 
in which Ewing originally described this species, with Cepheus 
Koch, 1836. This synonymy substantiates the writer's conclu- 
sion. The author does not have access to the cotype specimen 
of this species, the description of which was executed from Dr. 
Baker's pencil drawings in consolidation with Ewing's original 
description. 

Both of the above species differ from known representatives 
of their respective genera in their possession of heavy cero- 
tegument.

A Tabanus not Previously Known from the 
United States (Diptera: Tabanidae) 

By L. L. PECHUMAN, Lockport, New York 

Occasional female Tabanus of the line ola-vit tiger group from 
south Florida and the Keys show characters which have made 
it impossible to place them as any of the forms of this group 
known from continental United States. Most workers have 
placed them with a question as an anomalous form of Tabanus 
lineola scutellaris Walker. Specific placement in this group is 
more difficult with females than with males and until recently 
no associated males had been collected. 

A series of both sexes collected at Cape Sable, Florida, as 
prey of the wasp BembLv cinerca (Handl.) by Prof. H. E. 
Evans of Cornell University seems to have established the iden- 
tity of this form. The hairy, enlarged upper facets of the eye 
of the male places them as Tabanus vittiger Thomson. In Fair- 
child's (1942) revision of the group, the south Florida speci- 
mens key out to subspecies caymanicus Fairchild. A series of 
both sexes of caymanicus from the type locality, the Cayman 
Islands, loaned by Prof. Joseph Bequaert of the Museum of 
Comparative Zoology, compare closely with the Florida 
specimens. 

It is the writer's belief, however, that caymanicus is the same 
as Tabanus bellardii described by Szilady (1926) from Cuba. 
Szilady's description and figures match the specimens on hand 
in every detail. 

The Cape Sable specimens were collected on 24 March 1954. 
Females of Tabanus vittiger bellardii seen from other Florida 
localities include : Homestead, March, 1953 ; Key West, 8 July 
1952 ; Big Pine Key, 25 July 1947.

A Study of Oenocytes in Oryzaephilus mercator 

(Fauvel). (Coleoptera, Cucujidae) with 

Phase Microscopy 1 

By R. N. SINK A, 2 Department of Zoology, McGill University, 

Montreal, Canada 

Oenocytes are large cells associated with the fat body, and 
occurring exclusively in insects (Richards, in Roeder, 1953). 
Unlike fat cells oenocytes are ectodermal in origin and are well 
denned (Wigglesworth, 1953). In the present paper the loca- 
tion, arrangement, and histology of the oenocytes of imagines of 
Oryzaephilus mercator (Fauvel) are given. A description of 
this nature seems to be important because of our complete lack 
of knowledge of the specialized tissues in the hemocoel of spe- 
cies of the coleopteran family Cucujidae. 

The insects studied were reared in oats under controlled con- 
ditions of temperature and humidity (30 C and 75% R.H.). 
The imagines were approximately two weeks old and were 
taken from an inbred culture maintained for the last three years 
by Dr. J. Stanley at the Department of Zoology, McGill Uni- 
versity. They were fixed in Mukerji's fluid (Mukerji, 1937). 
Serial sections of the entire body of the insect, four to eight ^ 
in thickness, were made in transverse and longitudinal planes 
(Sinha, 1953). Unstained sections were cleared in cedarwood 
oil and mounted in permount. 

Phase microscopy has been used in different fields of biology 
(Richards, 1956), but its use in insect histology, especially in 
the study of fixed materials, is rather new. The author has 
found the following advantages in the use of phase microscopy. 
Unstained sections of fixed materials are as good as, or, in some 
respects, better than stained sections for the study of the mor- 
phology of cells. Greater detail in fine structures is often 
observed in an unstained section studied with phase microscopy 
than in a stained section with ordinary microscopy. This con-

elusion was reached by comparing a large number of unstained 
sections of the same species of insect with sections stained with 
Mallory's triple stain, and with Delafield's hematoxylin and 
eosin respectively. The elimination of a lengthy and compli- 
cated staining process enables one to avoid certain artifacts, and 
to examine a large number of slides in a reasonably short time. 
Of course, staining is important in the study of physiological 
and biochemical aspects of specific cells. Phase microscopy 
(Zeiss Winkel) with oil immersion was used with success in 
the study of the oenocytes described below. The drawing was 
made with the aid of a camera lucida.

thin layer of epidermis by one or more layers of the fat body. 
In some cases a few scattered oenocytes have been observed 
lying against the dorso-lateral wall of the gut, especially in the 
region of the proventriculus (Fig. 3). 

The oenocytes lie close together, often with adjacent walls. 
The individual cells are usually elliptical, 20 to 45 ju. long by 7 
to 11 ^ wide, and have a distinct cell wall. The cytoplasm is 
granular throughout and there is usually a single nucleus, al- 
though in some cells two or three nuclei have been observed 
(Fig. 3). The size of the nucleus varies, and it may be either 
rounded (Fig. 3) or elliptical (Fig. 2) in outline. Although 
studied in fixed materials these oenocytes lack the spindle 
shaped clefts or the radiating canals observed in other species 
of beetles (Wiggles worth, 1953). 

The author is grateful to Dr. H. R. Scott, Professor of His- 
tology, McGill University for giving helpful suggestions and to 
Mr. J. W. Pollock, Department of Zoology, McGill University, 
Montreal, Canada, for taking the photomicrographs used in this 
paper.

A New Mexican Eupompha (Coleoptera, Meloidae) 

By RICHARD B. SELANDER, Illinois Natural History 

Survey, Urbana 

The only species of Eupompha LeConte ( Calospasta Le- 
Conte) previously known to occur in southern Mexico is sulci- 
frons (Champion), which has been recorded from two localities 
in the Rio Balsas region of Guerrero (see Selander, 1954, Jour. 
Kansas Ent. Soc. 27: 84). It is consequently of some interest 
that among the material collected by the Hoogstraal Mexican 
Biological Expeditions of 1940 and 1941 there are representa- 
tives of a new species of Eupompha from Michoacan. 

Eupompha (Eupompha) terminalis, new species 

Orange. Apex of mandibles, eyes, scutellum, apical fifth of 
elytra, and under surface black. Under surface with a greenish 
luster. Antennae (except basal three to five segments) and 
coxae infuscate ; pronotum is one specimen with a median and 
two lateral infuscate marks at apex. Wings colorless except 
for brown apical area. Pubescence pale throughout. Length : 
12-14 mm. 

Vertex and upper frontal area smooth, shiny, sparsely micro- 
punctate, moderately, coarsely, sparsely punctate, clothed with 
short pubescence ; under side of head more finely, densely punc- 
tate, clothed with longer pubescence. Antennae filiform, moder- 
ately compressed ; segments not at all globular. Pronotum 
elongate, one-fourth to nearly two-fifths longer than wide ; disk 
regular, impressed anteriorly and on midline at base ; surface 
and pubescence of disk as on vertex, with longer pubescence on 
deflexed sides. Scutellum impunctate, glabrous. Elytra finely, 
confusedly scabro-punctate ; pubescence evenly, densely dis- 
tributed, semi-erect, moderately long, as long and as conspicu- 
ous as that on under surface of abdomen. Outer hind tibial 
spur greatly thickened, obliquely truncate, acute or subacute at 
apex ; inner spur like outer but more acute, shorter, only about 
half as wide. Tarsal claws as in Fig. 9. Under surface densely 
punctate and pubescent; pubescence longer on thorax than on 
abdomen. First segment of all tarsi clothed with regular cloth- 



124 ENTOMOLOGICAL NEWS [May, 1957 

ing setae beneath, lacking the more erect, sericeous pubescence 
which on other segments constitutes the tarsal pads. 

Male : Antennae extending five segments beyond occiput, 
weakly tapered to apex. Front of head (Figs. 1,3) with a very 
broad, very deep, impunctate, glabrous channel extending from 
epistomal suture to near center of vertex (not attaining occi- 
put) ; a well-marked sulcus on midline at bottom of channel 
between eyes; frontal area from top of eyes to epistomal suture 
greatly swollen on each side of channel to form a pair of large 
callosities which are strongly undercut by channel ; top of callosi- 
ties very finely punctate, sparsely clothed with a few minute 
setae. First four segments of fore tarsi greatly thickened ; 
dorsal side swollen, subimpunctate, glabrous, not sulcate. Sixth 
abdominal sternum moderately deeply, obtusely emarginate. 
Genitalia as in Figs. 5-6. 

Female : Antennae extending three segments beyond occiput, 
not tapered. Front of head deeply impressed along midline 
from epistomal suture to near center of vertex ; midline itself 
clearly indicated at bottom of this impression. Sixth abdominal 
sternum shallowly, triangularly notched at apex. 

Type Material: Holotype male from Apatzingun, 1200 ft., 
Michoacan, August 13, 1941, [H.] Hoogstraal. Allotypc fe- 
male, same data but August 21, 1941. Paratypes: one female, 
same data but August 18, 1941 ; one male, one female, same 
locality, semi-desert scrub, August 5, 1940, [H.] Hoogstraal and 
[K.] Knight. Holotype and allotype in the U. S. National 
Museum. 

This species is readily distinguishable from all other species 
of Eupompha on the basis of color. It is in all respects most 
similar to sulcijrons. In structural characters sulcifrons differs 
from tcrminalis mainly as follows : frontal channel of male lack- 
ing sulcus at bottom, not undercutting frontal callosities (Figs. 
2, 4) ; frontal impression of female wider, more evenly rounded 
in cross-section ; eyes larger, more prominent ; elytral pubescence 
distinctly shorter and sparser ; first four segments of male fore 
tarsi proportionately wider; male genitalia (Figs. 7-8) with 
gonocoxal (basal) piece proportionately narrower, gonostyli 
separated for less than half their length, and ventral hooks of 
aedeagus more apical in position.

E. sulcifrons, same. FIG. 9. E. terminalis, tarsal claw (middle leg). 

The morphological distinctness of terminalis and sulcifrons 
notwithstanding, the possibility that these two forms are races 
of a single species cannot be overlooked. So far as known, both 
are confined to the hot, arid valley system of the Rio Balsas. 
The few distributional data available suggest allopatry, snlci- 
jrons presumably ranging along the valley of the Rio Balsas 
proper and being replaced by terminalis in the valley of the 
Rio Tepalcatepec, a tributary of the Rio Balsas. In all proba- 
bility the ranges of the two forms are in contact, in which case 
it will be possible to determine their true taxonomic status 
through further field work.

Apatzingan area see Leavenworth (1946, Amer. Midland Nat.

A New Henicopid Chilopod from Peru 

By RALPH V. CHAMBERLIN, University of Utah 

The types of the henicopid herein described were collected by 
E. R. Ross and E. I. Schlinger in the course of the California 
Academy of Sciences expedition to the northern Andes areas 
of South America in 1954-55. These types are deposited in the 
California Academy. Records are also given for a previously 
known species of the same genus. 

ORDER LITHOBIIDA 
Family Henicopidae 
Lamyctes cerronus new species 

Reddish brown or somewhat chestnut. Length, 6 mm. 

A species agreeing with L. rcctns in lacking any definite ecto- 
dont on the prosternum, although a slight obtuse prominence 
may show in the place usually occupied by the ectodont when 
present in related species. The median sinus separating the 
dental series of the prosternum is wide as in rcctns, but in 
cerronus there is an acute incision at the middle of the sinus not 
present in the other species. Prosternal teeth 2-2. Cf. the 
accompanying figure. 




Prosternum of Lamyctes cerronus n. sp. 

Whereas in rectus tibial spines are present on leg 13, in the 
present form these are present only on the first twelve pairs of 
legs. In rectus the anal legs have the tibia ecjual in length to 
the first tarsal joint, but in cerronus it is longer than that joint 
in about the ratio 5:4.

HYDROPTILIDAE 

The known distribution of certain species of Hydroptilidae is 
greatly increased by the following data. The pattern is in two 
forms, one extending southward and roughly paralleling the 
Appalachian Mountains and the other extending westward 
across the northern states. Several species known only from 
Florida, Georgia and New Hampshire and two species recorded 
from British Columbia and New Hampshire accentuates the 
lack of Trichoptera collecting, especially in the Hydroptilidae.

Notes and News in Entomology 

Under this heading we present, from time to time, notes, news, and 
comments. Contributions from readers are earnestly solicited and will 
be acknowledged when used. 

Dancing Bees at the Equator and Nocturnal Dances. To 
those of our readers who have been following the amazing dis- 
coveries on communication in honey bees by Professor KARL 
VON FRISCH 1 and his students, the latest experiments of Dr. 
MARTIN LINDAUER - will be of great interest. 

In a number of publications, from 1946 to the present, von 
Frisch has revealed the dominant role that the sun plays in the 
orientation of bees, and that the shortcomings of the sun as a 
compass the fact that it is at times obscured by clouds and that 
it is constantly changing its position in the sky the bees know 
how to circumvent. For bees living in the latitudes between the 
tropics of Cancer and Capricorn there is still another problem, 
for here there are the times, twice a year, when the sun passes 
through the zenith and is then useless as a means of orientation. 

In Peradeniya, on Ceylon, as the sun approached the zenith, 
dances continued throughout the day up until April 2, when the 
sun at noon came to within 2^ of the zenith. On these days 
bees normally discontinued their flights between 11.40 and 12.30. 
When nevertheless induced to fly during the noon hour, the 
dances between 11.55 and 12.20 were disoriented. This shows 
that when the sun's position makes it useless as a compass, the 
bees are without any means for giving information on direction ;

they may, however, continue to visit the food, orienting their 
flights by means of the landscape. 

There are also other observations cited that help to determine 
exactly how close the sun may be to the zenith while the bees 
are still able to measure its azimuth accurately. Disoriented 
dances occurred only on the six days before and after the sun's 
passage through the zenith. Also, the dates were recorded when 
the change of dance direction around noon would be from the 
counterclockwise to clockwise, due to the sun passing now to the 
south instead of north of the zenith. All evidence indicates that 
the sun's azimuth is clearly observable by bees even when the 
sun is only 2| from the zenith. 

The facetted eyes of the bee thus represent a remarkably 
efficient apparatus for astronomical measurements. In this con- 
nection, it is noted that observations published years ago show 
that the angle of divergence of the ommatidia in the dorsal re- 
gion of honey bee's eyes is likewise 2\ \ 

Nocturnal Dances. Several years ago, while observing dances 
on the surface of swarms, Lindauer had found bees dancing at 
night, and that these dances were correctly oriented according to 
the (nocturnal) position of the sun at the time of the dance. 

In the present paper he describes the training of bees to two 
different stations. One and the same group of bees was trained 
to frequent a place east of the hive one hour before sunset, and 
a place west of the hive one hour after sunrise. When these 
bees now dance during the night, which place will their dances 
refer to? Perhaps to the place last visited, the afternoon sta- 
tion? Actual records taken throughout the night showed that 
the nocturnal dances before midnight refer to the afternoon 
station, those after midnight to the morning station, while close 
to midnight the dances are disoriented. This behavior is indeed 
a remarkable exhibition of memory and association. 

The problem of how the bees obtain their sure knowledge of 
the sun's position during every hour of the day and night called 
for further investigation. Is it congenital or do they learn it on 
their daily flights? 

In one experiment, a hive was flown overnight from Ceylon, 
on this day 5 35' south of the sun's path, to a locality near 
Bombay 5 35' north of the sun's path. It was found that now 



Ixviii] ENTOMOLOGICAL NEWS 133 

the bees confused their directions corresponding to the altered 
position of the sun in the sky. It was, moreover, also found 
that after several weeks the bees become adjusted to the new 
position of the sun. 

The fact that bees must acquire their knowledge of the sun's 
path by direct repeated observations, even in their native lati- 
tude, was also demonstrated. For this purpose, bees eclosed 
in an incubator and combined into a colony that was kept in a 
cellar with artificial illumination for four weeks were used. 
This hive was brought out and opened one day at noon, and 
that afternoon trained to a feeding place. The next morning 
these bees were unable to find the feeding place and were com- 
pletely disoriented. After a week in the open, a similar experi- 
ment showed that most bees were able to locate the next morn- 
ing a place they had been trained to the evening before, but 
there was still some uncertainty. 

Finally, Lindauer found that a thorough familiarity with a 
part of the sun's diurnal path suffices to permit a bee to derive 
the complete path of the sun inclusive of the nocturnal portion. 
A second colony, likewise of bees eclosed and kept in the dark, 
was brought outdoors daily at noon and permitted to fly freely 
only during the afternoons. After 35 days of this, the hive was 
transferred to a new locality, opened at noon, and during the 
afternoon trained to a feed place. That night the hive was 
transferred to still another locality and now opened at 8 A.M. 
Although this was the first time these bees had ever been out in 
the forenoon, the majority of bees flew in the correct direction 
to seek their food. If they can thus calculate the position of 
the sun during the morning, a time when they had never before 
seen it, there is no reason they should not be able to calculate 
its position during the night also. It is true the nocturnal 
dancers do not take into account the small irregularities in the 
rate of angular movement of the azimuth. In our latitudes the 
azimuth curves (azimuth plotted against time) are small, but 
near the equator they become very steep, and it remains to be 
determined how accurately nocturnal dancers in the tropics re- 
late their movements to the sun's position. R. G. SCHMIEDER.

Budapest Museum. A recent letter from Dr. ZOLTAN 
KASZAB of the Hungarian National Museum carries additional 
depressing news of the disastrous damage in October and No- 
vember. The Paleontology and Mineralogy sections suffered 
great destruction. Among the zoological exhibitions lost was 
the African Diorama, 25 meters long and modern in workman- 
ship. More serious losses, scientifically regarded, are : 30,000 
herps, 10,000 fishes, 40,000 birds, 30,000 eggs, 500,000 molluscs, 
and mammalian bones, including the African material of Kitten- 
berger. The insect collections were also damaged, especially 
the Diptera, of which 250,000 specimens (including 1,000 
types), 1,500 volumes and 6,000 separates were burned. 

Dr. Kaszab writes that the Museum Annals will probably be 
published this year as usual but includes in his letter the follow- 
ing (free translation) : 

"The replacement of the destroyed collections and renewal of 
scientific work in the museum surpasses our own resources and 
will be possible only through the sympathetic help of foreign 
institutes and foundations, zoological and entomological socie- 
ties. We ask of anyone who is able, help us ! I also ask you 
to make the contents of my letter widely known. The zoologists 
at the museum are all alive and working strenuously to salvage 
everything worth saving."- H. F. STROHECKER, University of 
Miami.

THE NEOTROPICAL SPECIES OF THE "SUBGENUS AESCHNA" 
SENSU SELYSII 1883 (Odonata). Memoirs of the American 
Entomological Society, Number 15 (Academy of Natural Sci- 
ences of Philadelphia). By Philip P. Calvert, Professor Emeri- 
tus of Zoology, University of Pennsylvania, and Editor Emeri- 
tus of the Entomological News. 

For many years odonatologists have been aware of the need 
of an adequate revision of the many species of Aeshna (sensu 
lato) of South and Central America. For some years past, 
however, it has been well known that Dr. Calvert was working 
on this project and now this gap in our knowledge of dragonflies 
has been filled. 

Dr. Calvert's report is an imposing document of 251 pages 
of text, 614 figures arranged on 47 plates, 19 tables of venational 
and other measurements and 7 maps showing both geographical 
and altitudinal distribution of all the species and subspecies 
treated in the study. 

Thirty-eight species comprise the neotropical members of the 
three genera recognized, but forty are actually considered, since 
two species of Hespcraeschna, a typically neotropical subgenus 
of Aeschna, are unknown south of Baja California, Mexico, one 
of these being the type species, Aeshna (//.) calif ornica Calvert. 

The main body of the study is divided into seven parts, the 
first and by far the largest part dealing with the adult dragon- 
flies, the second with the larvae, while the remaining parts are 
brief dissertations on the following topics: III Relationships 
of the Neotropical Aeshnas to the North American fossils ; IV 
Relations of the South American Aeshnas to Palearctic and 
Australian species ; V The Geological Age and Geographical 
Distribution of the Ancestors of the Odonata and Mammalia; 

VI Relations of the Neotropical Aeshnas to each other ; and 

VII The Seasonal Distribution of the Neotropical Species of 
Aeshna. 

In the introductory pages of Section I a full account is given 
of the historical events leading to the fixation of the generotype 
of Aeshna Fab. as A. grandis L. by Cowley in 1934. This is 
followed by an all-inclusive key to genera, subgenera, species and 



136 ENTOMOLOGICAL NEWS [May, 1957 

subspecies. Being of the descriptive kind, a number of charac- 
ters are used, not only venational and genitalic but also many 
others from various regions of the body, including color pattern. 
Such a key may be more time-consuming than the usual shorter 
kind but is far more reliable. Immediately following the key a 
number of abdominal details are described, these having been 
used as taxonomic characters for the first time in the present 
work. 

No pains have been spared to make this study as complete and 
accurate as possible. In the descriptive part the treatment of 
each species includes an apparently complete list of references in 
chronological order, numbered consecutively, and detailed state- 
ments as to sources of material and distribution of species and 
subspecies, not only geographical but also altitudinal and sea- 
sonal. Under the caption "Ecology" are various field notes, 
often copied as exactly as possible from the collector's label, this 
being usually necessary since adequate accounts of the habits or 
haunts are rarely available in published form. Finally, under 
"discussion" are considered the numerous problems, chiefly tax- 
onomic, which inevitably arise in a work of this kind, particu- 
larly in the case of little-known species. 

A total of 40 species of the "subgenus Aeschna" sensu Selysii 
1883 are treated in this work. These include some more re- 
cently described species belonging to the same "subgenus" and, 
as already stated, two that are not actually Neotropical in 
distribution. 

As now classified, these 40 species belong to three genera, 
Aeshna, Coryphaeschna and Castoraeschna. Coryphaeschna 
was separated from Aeshna in 1903 by E. B. Williamson, the 
generotype being A. ing ens Rambur and other species of Aeshna 
were transferred to the new genus by various workers, including 
Calvert. Six species are now referred to Coryphaeschna, all 
inhabiting the Neotropical Region, although C. ingens pene- 
trates North America as far as North Carolina. 

The only new genus that appears in the present study is 
Castoraeschna, although it should be noted that Dr. Calvert 
published preliminary diagnoses of this new genus and his new 
subgenera of Aeshna in 1952 (Ent. News, 63). Five species 
belong to Castoraeschna and all but one of them had been placed 



Ixviii] ENTOMOLOGICAL NEWS 137 

in Coryphaeschna by Ris or Kimmins, including the generotype 
Aeshna castor Brauer. 

The remaining species are placed in the genus Aeshna, but 
this genus, as represented in the Neotropical Region, is now sub- 
divided into six nominal subgenera, namely, Aeshna, Hesper- 
aeschna Cockerell, Rhionaeschna Foerster, Schizuraeschna Cal- 
vert, Marmaraeschna Calvert, and Neureclipa Navas. Only 
two species are referred to the typical northern subgenus Aeshna 
and these are both too little known to give much assurance that 
they actually belong to this subgenus. Rhionaeschna, repre- 
sented by a single species not seen by Calvert is doubtfully dis- 
tinct from Hesperaeschna, the dominant neotropical subgenus. 
This leaves thus four well defined and well established subgenera 
of Aeshna in the region considered. 

The largest and most widely distributed of these subgenera is 
Hesperaeschna, whose 14 species together have an unbroken 
range from Terra del Fuego (A. variegata} to southern British 
Columbia {A. calif arnica}, a latitudinal range of 102 degrees. 
None of the other subgenera or even genera approach Hesper- 
aeschna in latitudinal range. Coryphaeschna comes second with 
66 degrees, and likewise entering North American (North 
Carolina), while the third is the subgenus Schisuraeschna (60), 
which ranges even farther north than Hesperaeschna (A. multi- 
color to southern British Columbia), although the southward 
extension of its range is only to Panama or possibly Venezuela 
(A. jalapensis). There are only four species each of the sub- 
genera Marmaraeschna and Neureclipa, and three of Schisur- 
aeschna, so that the total number of species of Aeshna, includ- 
ing two in the subgenus Aeshna and one of Rhionaeschna is 28. 
The 7 species of Coryphaeschna and 5 of Castoraeschna make 
the total number of species described 40. 

Comparatively little larval material was available for Dr. 
Calvert's study but that little has been most carefully investi- 
gated. The key to the larvae is modified from the keys of 
Wright and Peterson (1944, Ohio Jl. Sci. : 151-161) and Need- 
ham and Westfall (1955, Manual N. Amer. Drgfls. : 253-255). 
Although the larva of Coryphaeschna ingens, the generotype of 
this genus, is strikingly unlike the typical Aeshna larva, the dif- 
ference between larvae of these two genera may be very slight. 



138 ENTOMOLOGICAL NEWS [May, 1957 

Castoraeschna is still unknown in the larval state and, as far as 
any of the genera are concerned, larvae of less than a dozen 
species and subspecies are known with certainty. This is, how- 
ever, as many as could be expected in a group whose larvae 
have not yet been systematically collected or reared. 

Dr. Calvert's study is profusely illustrated, partly from photo- 
graphs, partly from line drawings, but the great majority of the 
figures are from pencil drawings, reproduced in halftone. These 
drawings are most carefully and accurately executed, but the 
lack of contrast of pencil drawings is increased in the reproduc- 
tion, so that they appear somewhat dull and flat. Nevertheless, 
the figures perform their main function, accurately representing 
the parts which they illustrate. 

The final impression left on the mind of the reviewer after a 
careful scrutiny of this work is that of an extremely exact and 
detailed study in which nothing has been done hastily and no 
opinion expressed on any problem without due consideration of 
every one of its angles. 

Besides being a work that every serious odonatologist will 
desire to possess, this monograph will doubtless be wanted for 
entomological libraries everywhere, particularly those in Cen- 
tral and South America. EDMUND M. WALKER. 

THE BIOLOGY OF THE HETEROPTERA; by N. C. E. Miller. 
Pp. 162, 64 figs. Leonard Hill Ltd. 9 Eden Street, London 
N.W. 1. 30 s. 

This small book by Professor Miller will be of considerable 
value to the general entomologist and the specialist in Heterop- 
tera as it contains numerous fine illustrations of adult and imma- 
ture stages of many species of the suborder. For almost the 
first time, all of the heteropterous families are brought together 
and discussed in a single volume and the author as a result of 
his extensive work in the tropics of the Eastern Hemisphere has 
been able to avoid the over-emphasis upon Holarctic species so 
evident in most general works. A useful list of family and sub- 
family names and their synonyms is included. Particularly 
valuable is the extensive section on the Reduvoidea of which 
group Dr. Miller is one of the great authorities. 



Ixviii] ENTOMOLOGICAL NEWS 139 

From specialists in the group have come expressions of regret 
on account of many errors and omissions, and the poor balance 
of the work. For example, 101 of the some 152 pages of text 
are devoted to discussions of the various families. The Redu- 
voidea are treated in 40 pages, the Tingidae receive three- 
fourths of one page, the Coreidae four pages, the Lygaeidae 
slightly less than three pages and the Miridae (the largest fam- 
ily of Heteroptera) are treated in two and one-half pages. 

Any book of this type must, of course, be highly selective, but 
in view of some of the very limited references included it is sur- 
prising to find no mention of such important biological papers 
as Bailey's on the Tingidae, Esselbaugh's on Pentatomidae, 
Blatchley's "Heteroptera of E. N. America," Renter's classic 
work on the Heteroptera of Palearctic Conifers and a great 
many others. 

Much important biological information is lacking. To take 
two examples, maternal care in Heteroptera is very casually 
discussed without reference to the important papers on the sub- 
ject by Bequaert, Frost & Haber and Kirkaldy among others 
and there is no consideration of the important Mullerian and 
Batesian mimicry phenomena exhibited by some members of 
the suborder. 

Statements of the geographic distribution of the various fami- 
lies is unfortunately most misleading. The Isometopidae are 
said to be Palearctic and Oriental, the Berytidae Ethiopian and 
Indo-Australian, the Aradidae Palearctic and Nearctic, and the 
Salclidae Nearctic and Palearctic. 

Economic workers will certainly object to the omission or 
summary treatment of such destructive species as Antestia linea- 
ticollis, Anasa tristis, Blissus leucopterus, Nysius ericae and 
Nysius vinitor among others. 

The book appears to be valuable for students of the Redu- 
voidea and for general workers in providing an overall view of 
the groups of Heteroptera and for its excellent illustrations. It 
must, however, be used with great caution and by no means 
represents a definitive work upon the biology of the Heteroptera.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

Notes on the Biology of a Parasitic Bee, Isepeolus 
viperinus (Hymenoptera, Anthophorinae) x 

By CHARLES D. MICHENER - 

The purpose of this paper is to present information on the 
biology of the South American parasitic bee, Isepeolus viperinus 
(Holmberg). The observations are fragmentary but, in view 
of the interesting structural and behavioral parallelisms that 
occur among various parasitic bees, it seems worth publishing 
them, especially since very little has been known previously of 
the biology of any Protepeolini. 

The so-called parasitic bees that inhabit nests of solitary bee 
hosts are inquilines after the manner of cuckoos. They lay their 
eggs in the cells of the host ; each larva destroys the egg or 
young larva in a cell of the host, then eats the food stored by 
the host. When a parasite locates a host nest, she revisits it 
from time to time in order to lay an egg in each cell, or at least 
in more than one cell. Even though the parasites occur in

different families, they exhibit a remarkable series of paral- 
lelisms. Some of those relating to adult morphology have been 
treated by Grutte (1935), Michener (1944), and others. A 
most remarkable parallelism concerns the first stage larva, which 
in various parasites is equipped with an enormous head and 
jaws which are used to destroy the egg or young larva of the 
host. This modification occurs in such parasites as Coelioxys 
(Megachilidae), Melecta, Oreopasites, Epeolus, Triepeolus, and 
Noniada (Anthophorinae). It is possible that this character is 
an indication of phylogenetic relationship of the last three, but 
must have arisen independently in Coelioxys and Melecta, and 
probably in Oreopasites. Another parasitic bee, Stelis, how- 
ever, has nearly normal first stage larvae. It is interesting to 
find that Isepeolus has a large head and jaws in this stage, just 
as do its parasitic relatives in the Anthophorinae. 

The genus Isepeolus has been recorded as a parasite of Col- 
letes previously (Claude- Joseph, 1926; Ruiz, 1942, 1944, under 
the name Epeolus luctuosus Spinola), but information on imma- 
ture stages has been limited to notes on the mature larva by 
Claude-Joseph. 

The observations here recorded concern its parasitism of 
Colletes kerri Moure. The ethology of this species has been 
discussed elsewhere (Michener and Lange, 1957). 

Among 25 occupied cells of C. kerri collected from nests in 
an earth bank at Araucaria, Parana, Brazil, on January 13, 
1956, 6 were occupied by cocoons of Isepeolus, the others by 
pupae of the Colletes. The Isepeolus cocoons are 11 to 12 mm. 
long, 6 mm. wide, strong, firm, made of coarse brown fibers 
sometimes as much as .02 mm. in diameter, criss-crossed, fused 
at points of crossing. These form an outer layer separable with 
difficulty from a second layer of finer fibers partially imbedded 
in an amorphous membrane. This layer is easily separable from 
a third which is similar to the second. The fourth and inner- 
most layer, separable with difficulty from the third, is very thin, 
almost without fibers or with only very fine pale ones, and is 
thus mostly amorphous material. It is very smooth and shining 
on the inner surface except near the anterior end where it is more 



Ixviii] ENTOMOLOGICAL NEWS 143 

fibrous, less smooth, and with some open interspaces among the 
fibers. The thickness of the whole cocoon wall is about .28 mm. 
The outside of the cocoon is fairly uniformly covered with a 
layer of fecal matter and perhaps unused pollen. This layer is 
.1 to .2 mm. thick, and blackish; separate fecal pellets cannot 
be recognized. 

At the time that these cocoons were collected one adult was 
already chewing its way out through one end of its cocoon. 
Others were still pupae, but all had emerged by January 25. 

Other observations on the relations between Isepeolus viperi- 
nus and its host were made in a series of banks near Curitiba, 
Parana, Brazil, which are termed for our purposes the Bangui 
roadside banks. They are described in detail by Michener, 
Lange, Bigarella, and Salamuni (1958). On February 26, a 
female Isepeolus viperinus was seen to enter a known nest of 
Colletes kerri. The nest was left undisturbed, but on March 4 
it was excavated. It contained two cells, both of which were 
occupied by young Isepeolus larvae. The latter were straight 
(unlike the curled Colletes larvae) and floated at the surface of 
the semiliquid provisions. They had killed the Colletes larvae, 
but the remains of the latter were uneaten in the mass of pro- 
visions ; apparently Isepeolus larvae do not eat those of their 
host. 

A young Isepeolus larva is shown in fig. 1, with a young 
Colletes larva drawn to the same scale in fig. 2. The two draw- 
ings were traced from a photograph of living larvae removed 
from the cells. The young larva of Isepeolus is remarkable for 
being nearly straight, the body with thick projecting lateral 
folds, especially posteriorly, which disappear in larvae of the 
same stage which have fed and are more distended. The body 
is remarkable among Anthophorinae for having a few hairs, 
especially in the anterior half. The large, depressed, heavily 
sclerotized head is also rather hairy. Sclerotization extends 
back as a spreading shield over the anterior part of the pro- 
thorax, especially ventrally, as shown in figs. 3 and 4, where 
membranous areas are stippled. The pointed labrum, relatively 
long antennae, absence of palpi, and the large sickle-shaped 



144 ENTOMOLOGICAL NEWS [June, 1957 

mandibles are noteworthy features. However, the fusion of 
the labium, maxillae and hypopharynx to form an undivided 
ventral plate which is completely fused with the head capsule 
and has the salivary opening exposed on its ventral surface is 
a most remarkable modification of the pattern seen in related 
nonparasitic Anthophorinae (e.g., Anthophora, see Michener, 
1953). A deep midapical emargination in this plate is sur- 
rounded by downflexed margins (fig. 5). The posterior ten- 
torial pits are reduced to a pair of inconspicuous depressions, 
from which exceedingly slender tentorial rods extend ante- 
riorly ; no tentorial bridge was seen, nor were anterior tentorial 
pits located. 

The head is so differently modified from that of Oreopasites 
(Rozen, 1954), another parasitic anthophorine whose young 
larval head has been studied with some care, that it may be that 
the head enlargement and sclerotization in Oreopasites and 
Iscpeolus larvae have been independent. In Oreopasites the 
labrum is deeply bifid, the antennae and palpi are small but 
recognizable and the maxillary and labial area is separated from 
the rest of the head. These are primitive features which agree 
with bee larvae in general. Hence it is reasonable to state that 
the primary larvae of Oreopasites are less specialized than 
those of Isepeolus. Unfortunately, those of other parasitic 
Anthophorinae have not been described in sufficient detail to 
permit comparison. 

One might imagine that larvae so modified could only kill 
the egg or larva of the host and could not feed on the stored 
food. This is not the case, for one small larva, presumably first 
stage, had the body distended with pollen. 

Finally, it should be noted that a prepupa of Isepeolus viperi- 
nus was found in a cocoon in the nest of an unknown species of 
Colic tes (not kern) near Restinga Seca, 20 km. east of Pal- 
meira, Parana, Brazil, on January 27, 1956. This prepupa 
pupated in mid-February and emerged in the laboratory in early 
March. Apparently this individual belonged to a population not 
synchronized with Colletcs kerri but rather with its own host.

Morphologically it agreed with specimens reared from nests of 
C. kerri. 

As the pupa of Isepeolus has not been described, the following 
notes may be useful : No pubescence ; no spines on coxae or 
elsewhere ; a pair of tubercles on vertex near ocelli ; a pair of 
large tubercles behind middle of mesoscutum. This pupa, as 
can be seen from the study of bee pupae by Michener (1954), 
has fewer spines and projections than any other bee pupa known. 
Perhaps this is because the adult is largely devoid of long hairs ; 
in the paper mentioned above it is suggested that pupal spines 
serve principally to provide space for the development of the 
long hairs characteristic of most nonparasitic bees.

Redescriptions of Ewing's Oribatid Mites, III 
Family Eremaeidae (Acarina: Oribatei) ' 

By TYLER A. WOOLLEY, Department of Zoology, Colorado 
A. & M. College, Fort Collins, Colorado 

This paper delineates several redescriptions of oribatid mites, 
the original accounts of which were made by the late Dr. Henry 
E. Ewing. The article is a sequential part of a series pro- 
posed by Dr. E. W. Baker of the U. S. National Museum. 
The writer follows Ewing's descriptions as far as possible, but 
uses modern acarological terms. 

FAMILY EREMAEIDAE WILLMANN, 1931 

According to Willmann (1931) this family of aptyctimous 
mites is characterized by the lack of pteromorphae, legs shorter 
than the body and leaf-like or ridge-like lamellae. Legs III 
and IV are usually inserted at the lateral margins of the 
hysterosoma. 

The first three species redescribed below are representatives 
of the genus Lucoppia Berlese, 1908, in which the narrow, 
ridge-like lamellae converge, the pseudostigmatic organ is capi- 
tate, with a globe on a short, thin stalk. The last species dis- 
cussed in this paper is in the genus Eremaeus Koch, 1836, 
which is characterized by reduced, parallel lamellae, short tarsi 
with three claws and apodemata IV fused into a sclerotized band 
which surrounds the genital aperture. 

Lucoppia magnipilosa (Ewing), 1909. (Figs. 1, 2) 

Type: Damacus magnipilosus Ewing, 1909, p. 130. 

Description: Olive brown in color, integument rough, with 
small, raised kernels. Propodosoma triangular (specimen tilted 
on slide), rostrum rounded anteriorly; rostral hairs simple, 
incurved at tips, inserted half their lengths posterior to rostral 
tip. Lamellae not noticeable except as slight ridge on right

Foundation. 



148 ENTOMOLOGICAL NEWS [June, 1957 

side. Lamellar hairs a third longer than rostral hairs, erect 
and inserted two-thirds their lengths directly posterior to rostral 
hairs. Interlamellar hairs simple, about same size as lamellar 
hairs, erect, inserted between pseudostigmata. Pseudostigmata 
cylindrical, low, slightly raised above surface of propodosoma, 
cornuate beneath. Pseudostigmatic organs small, erect, with 
narrow, short peduncle and globose head. Tectopedia I lateral, 
between levels of pseudostigmata and lamellar hairs. 

Hysterosoma oval, wider anteriorly in tilted specimen, longer 
than broad. Dorsum with eleven pairs of long, fine, simple 
setae. Each seta finely serrate as shown in fig. 1. Two poste- 
rior median pairs of setae shorter than others. Ewing's de- 
scription states : "At the posterior margin of the abdomen are 
situated two pairs of short, stout, fusiform bristles, character- 
istic of this species ; the upper two are about twice as long as the 
lower two, and both pairs are inclined away from the median 
plane." In the specimen from which this description is con- 
structed these dorsal hairs are fine and not stout. There are, 
however, two short, fusiform adanal hairs on the venter, which 
Ewing may have viewed from above, but none of the setae on 
the dorsum is stout. 

Camerostome oval as seen in tilted specimen, with two simple 
bristles posterior to chelicerae. Other bristles as shown in 
fig. 2. Ventral plate shield shaped, anterior margin of shield 
formed by curved apodemata IV. Genital opening oval, nearly 
three times its length from anal aperture, anterior margin con- 
tiguous with curved front margin of ventral plate adjacent to 
apodemata IV. Each genital plate longer than broad and with 
five simple setae inserted closer to lateral margin than to 
medial (fig. 2); g:l inserted on anterior margin of genital 
plate; g:5 inserted in middle of posterior edge; g:2, g:3, g:4 
and g : 5 equidistant from each other, a slightly wider separation 
between g : 3 and g : 4. Anal aperture nearly square ; anal 
plates nearly three times as large as genital plates, longer than 
broad, with two anal setae; a:l inserted laterally on plate, a: 2 
shorter and closer to median and posterior margin of plate 
(fig. 2). 



Ixviii] ENTOMOLOGICAL NEWS 149 

According to Ewing the anterior pair of legs are as long as 
entire body, the leg segments less swollen than in other species. 
He describes all legs with stout, curved, pectinate hairs and leg 
IV as the longest of the legs. 

Length 725 /j., hysterosoma 528 /A ; width 428 /j.. 

Discussion: The original description by Ewing (1909a) is 
slightly different in some respects from the current redescrip- 
tion. The specimen described above is not the type, but bears 
the same identification as the type. According to Ewing the 
type species was collected by J. D. Hood at Urbana, Illinois, 
under the bark of soft maple. The specimen described above 
is one collected by C. R. Crosby at Columbia, Missouri, and 
mounted June 19, 1908. 

Lucoppia curviseta (Ewing), 1909. (Figs. 3, 4) 

Type : Notaspis curviseta Ewing, 1909, p. 105. 

Description: Dark reddish brown, integument thick and hard. 
Propodosoma narrowly triangular, about one third as long as 
body, expanded laterally in outline by projection of tectopedia I 
and II. Rostrum rounded; rostral hairs simple, erect, about 
half as long as lamellar hairs, inserted three-fourths their lengths 
from tip of rostrum at lateral margins. Lamellae narrow, con- 
vergent bands or ridges on surface of propodosoma, extended 
from base of pseudostigmata to level of anterior margin of 
tectopedia I, expanded distally for insertion of lamellar hairs. 
Lamellar hairs about as long as propodosoma, finely serrate 
(Ewing states: "pectinate"), directed forward. No trans- 
lamella. Interlamellar hairs about three-fourths as long as 
lamellar hairs, simple, erect, but curved outward and upward, 
inserted near lamellae, antero-mediad of pseudostigmata. Pseu- 
dostigmata small, circular pits, slightly larger in diameter than 
width of lamella. Pseudostigmatic organ short, directed antero- 
laterad, with straight, narrow pedicel, a spherical head at level 
of tectopedia II. Tectopedia I and II as shown in fig. 3. 

Hysterosoma subglobose, slightly broader in front, anterior 
margin indented laterally to form a small scallop around inser- 
tion of first pair of setae directly behind tectopedia II ; first 



150 ENTOMOLOGICAL NEWS [June, 1957 

pair of setae straight, directed laterad ; dorsmn with thirteen 
pairs of simple, curved setae (Ewing says: "pectinate"). Four 
pairs of areae porosae, one pair posterior to shoulder of 
hysterosoma, three pairs postero-lateral in position (fig. 3). 
A glandular fissure postero-laterad of fourth pair of hystero- 
somal bristles. 

Camerostome subtriangular, two setate immediately posterior 
to chelicerae. Other setae as in fig. 4. Apodemata I and II 
long, narrow, directed mediad; apodemata III and IV short, 
curved, extended mediad a fourth the distance to genital open- 
ing. Anterior margin of genital aperture contiguous with apo- 
demata II, opening nearly square in outline, about three times 
its length anterior to anal aperture. Each genital plate rectangu- 
lar, with straight, medial margin, rounded lateral corners ; four 
short, fine genital setae on each plate; g:l and g:2 anterior, 
g:3 and g:4 posterior (fig. 4). Anal aperture nearly three times 
as large as genital opening, somewhat polygonal in outline. 
Anal covers with two fine, curved hairs inserted closer to 
medial margin than to lateral. Two pairs of stout, fusiform,

Lucoppia boletorum Ewing, 1913, p. 120. (Figs. 5, 6) 

Description: Light yellowish brown. Propodosoma longer 
than broad, rostrum blunt. Rostral hairs inserted in slight 
prominences a third their lengths from rostral tip. Lamellae 
less than half the length of propodosoma, low sclerotized ridges 
apparently extending to pseudostigmata, but interrupted by 
insertion of interlamellar hairs. Lamellar hairs pectinate, 
curved ; inserted in low crescentic pits at anterior end of lamellae, 
reaching nearly to insertion of rostral hairs. Interlamellar hairs 
pectinate, divergent, a third longer than lamellar hairs, inserted 
in slightly curved, medial projections of lamellae, closer to 
pseudostigmata than to lamellar hairs. No translamella. Pseu- 
dostigmata cup-like ; pseudostigmatic organs short, with narrow 
pedicel and subglobose, simple head. 

Hysterosoma somewhat oval (except for broken dor sum on 
right side), surface irregular, but not pitted; dorsum with eleven 
pairs of slightly pectinate, curved setae (fig. 5). Areae porosae 
as shown in fig. 5. 

Venter misshapen due to breakage of specimen. Apodemata 
I curved around base of camerostome ; apodemata II directed 
medio-posteriorly from between tectopedia I and II. Apode- 
mata III nearly horizontal at level anterior to genital aperture, 
not extended to margin of latter. Genital opening about two 
and one-half times its length from anal aperture, rounded; 
genital covers with straight medial margins, rounded laterally ; 
genital setae not visible, a single setal insertion in postero- 
lateral corner of left cover. Anal opening about twice the size 
of genital opening, each anal cover with a single visible seta. 
An adanal seta adjacent to postero-lateral ir^argins of anal aper- 
ture.

Length 614 /A, hysterosoma 470 /A. 

Ewing (1913) states that this species was collected by J. E. 
Guthrie at Jordan, Minnesota. 

Discussion: According to Ewing (1913) this species is simi- 
lar to L. pilosus (Banks), but he differentiates L. boletorum on 
the basis of an almost circular hysterosoma and shorter lamellar 
hairs. The fact that the specimen of the latter species is broken 
makes exact comparisons difficult. 

Eremaeus brevitarsus (Ewing), 1917, nov. comb. (Figs. 

7,8) 

Cotype : Damaeus brevitarsus Ewing, 1917, p. 164. 

Description: Propodosoma large, bluntly triangular in out- 
line, narrower than hysterosoma and about two thirds as long, 
with small tubercles on lateral and posterior surfaces (fig. 7). 
Rostrum broad and blunt, rostral hairs inserted in slight notches 
at lateral edges of propodosoma approximately half their lengths 
from anterior tip. Lamellae small, elongated, triangular promi- 
nences, about as long as rostral hairs, located on dorsal surface 
of propodosoma, with anterior cusp that projects above surface 
of propodosoma. Lamellar hairs short, about one-fourth as 
long as lamellae, each inserted in tip of anterior lamellar cusp 
and slightly decurved. Translamellae reduced to small medial 
projections on inner edges of lamellae. Interlamellar hairs 
stouter than lamellar hairs, but about same length, pectinate, 
inserted antero-mediad of pseudostigmata. Pseudostigmata cir- 
cular and pit-like, as wide as half the length of interlamellar 
hair, nearly three times their diameters from anterior margin of 
hysterosoma. Pseudostigmatic organ elongate, club-like and 
pectinate, extending almost directly laterad from pseudostigmata. 

Tectopedia I prominent, posterior to level of lamellar hairs, 
but directly laterad of lamellae. Tectopedia II a prominent, 
notched lateral tubercle at postero-lateral angle of propodosoma 
between legs II and III. 

Hysterosoma longer than broad, swollen and slightly oval in 
outline, truncate anteriorly, anterior margin apparently flat- 
tened behind propodosoma, shoulder regions sclerotized ; nine 
pairs of fine, dorsal setae; integument smooth (fig. 7). 



Ixviii] ENTOMOLOGICAL NEWS 155 

Posterior margin of camerostome angular ; setal insertions at 
level of tectopedia I and medial. Apodemata II and III trans- 
verse bars, each ending in curved, sclerotized coxal insertions ; 
apodemata IV coalesced with sclerotized margin of genital 
aperture. Two pairs of setal insertions anterior to genital 
aperture on each side of sclerotized bar between apodemata III 
and IV 7 , a single setal insertion mediad of coxal insertion IV. 
Genital aperture oval in outline, surrounded by sclerotized ring 
formed by apodemata IV ; each genital cover subrectangular, 
with six genital setae in a row near medial edge of cover. Anal 
opening trapezoidal, each cover somewhat triangular, opened 
slightly in cotype specimen (fig. 8), with two setae; two pairs 
of adanal setae, fine, simple, subequal in length. 

Ewing (1917) describes the legs of this species as follows: 
"Legs . . . with short, globose tarsi ; femora swollen but not 
globose though pedicellate at their bases. Anterior pair of 
legs extending beyond the tip of the rostrum by about two 
thirds their length; tarsi slightly shorter than the tibiae; tibiae 
each with distal tubercle and long tactile hair which extends 
beyond the tip of the tarsus. Tarsi of posterior legs strongly 
globose scarcely two thirds as long as the tibiae ; tibiae not 
globose, bearing each a very long tactile hair distally which 
extends beyond the tips of the tarsi. Ungues of all tarsi 
unequal." 

Length 580 /x; width 300 p.. 

Ewing mentions that a single specimen was found by him 
beneath an old piece of wood at Ames, Iowa. 

Discussion: Two discrepancies exist between the Ewing's 
original description and the cotype described above. Ewing 
indicates the lamellar hairs as large, straight, simple bristles 
which extend beyond the rostrum. The pencil drawing of the 
cotype indicates these as short and decurved. Ewing's original 
illustration shows four setae in the shoulder region ; the cotype 
exhibits three. Minor differences in the lamellae also exist as 
illustrated here and as drawn by Ewing. 

This species resembles Ereinaeus foveolatus Hammer, 1952, 
but differs in the shorter length of the interlamellar hairs, lack of 
pits on the hysterosoma and the shorter, cusped lamellae.

First Record of Endochironomus subtendens 

(Townes) Larval Overwintering Cocoons 

from North America (Diptera: 

Tendipedidae) * 

By PHILIP A. BUSCEMI, Department of Biological Sciences, 

University of Idaho 

During the course of a year-round study of the bottom fauna 
of Parvin Lake, Colorado (located in Larimer County at an 
altitude of 8200 feet), an unusually large number of overwinter- 
ing cocoons of Endochironomus subtendens 2 larvae were col- 
lected from the plant detritus of Elodea canadensis in the inlet 
bay. To date, they have been reported only four times from 
certain European lakes: by Harnish (1922) from a pond of 
the Silesian plain, by Aim (1922) from Yxtasjon in central 
Sweden, by Decksbach (1933) from the Russian Pereslawskoje 
Lake, and by Thienemann (1954) from some north German 
lakes. This, then, is the first North American record for such 
overwintering cocoons of Endochironomus. 




Overwintering cocoon of Endochironomus subtendens, X 20 

Cocoons were collected by the writer as early as October 20, 
1952, but the great majority were taken between November 28, 
1954 to May 8, 1955. Most of the cocoons were found at 
depths of 0.3 to 3.0 m. They thus occurred over a slightly

158 ENTOMOLOGICAL NEWS [June, 1957 

greater depth range than that reported by Thienemann, who 
collected them only between 1.0 and 2.0 m. The maximum 
concentration on the bottom of the inlet bay was recorded at 
1.0 m. (4928 per sq. m.) on February 26, 1955. The cocoons 
averaged 4.0 mm. long and 1.6 mm. wide (i.e., somewhat smaller 
than those described by Thienemann). They are weakly con- 
cave along the mid-line, and the ends are approximately semi- 
circular in shape (fig.). The larvae are bent at 180 at the 
mid-point of their length, and the head and caudal regions 
occupy the same end of the cocoon. 

A number of cocoons measuring only 1.4 mm. in length were 
also collected in the samples, so that apparently all three larval 
stages have the ability to build overwintering cocoons. The 
cocoon is closed on all sides and is constructed of silk-like oral 
secretions to which bits of inorganic detritus and diatoms 
adhere. Their color is dark yellow to brown. 

On the basis of near-bottom water temperature data, larvae 
of E. subtendens start to build cocoons shortly after the mini- 
mum daily water temperature falls to 10 and the mean daily 
water temperature falls below 13. This latter temperature was 
first recorded in the inlet bay on November 20, 1954. Eight 
days later cocoons were found in the dredgings. Conversely, 
the mean critical temperature for reactivation of the larvae in 
the spring must lie between 5 and 9. Over 50 per cent of the 
larvae had become active on April 22, 1955, when the mean 
daily water temperature was 5.3, and over 70 per cent were 
active by May 8, 1955, when the mean temperature had in- 
creased to 9.3. 

Representative specimens are in the collections of the United 
States National Museum.

New Longicorn Beetles from Texas (Coleoptera, 

Cerambycidae) 

By E. GORTON LINSLEY, University of California, Berkeley 

The following species are described in order that the names 
may be available in connection with another study. 

Heterachthes texanus Linsley, new species 

Male : Form slender, small ; integument uniformly dark brown, 
surface subglabrous except for very long erect pale setae which 
are longer than greatest width of femora; elytra without pale 
markings. Head coarsely, irregularly punctate between eyes; 
antennae very heavy, exceeding elytral apices by about three 
segments, segments three to six greatly swollen, thicker than 
scape, apically ciliate but not carinate, segments seven to eleven 
filiform. Pronotum dull, coarsely, rugosely punctate, a little 
more than one and one-half times as long as basal width ; pro- 
sternum shining, subglabrous ; metasternum shining, glabrous 
practically impunctate. Elytra dullish, with scattered coarse 
punctures bearing very long setae ; apices separately rounded. 
Legs moderate ; femora clavate, with scattered long erect setae. 
Abdomen shining, subglabrous, almost impunctate. Length, 
4.5 mm. 

Holotype male (Calif. Acad. Sciences, Entom.), from the 
Chizos Mts., Big Bend, TEXAS, July 5, 1942 (E. C. Van Dyke). 

This is a small, obscure species, easily known by the uniform 
dull coloration above, shining impunctate ventral surface, ex- 
tremely heavy basal segments of the antennae and the very long 
erect setae of the elytra and legs. 

Crossidius inflaticollis Linsley, new species 

Male : Form large, subparallel ; integument dull, red, antennae, 
legs, scutellum, and sterna of meso- and metathorax black, 
elytra with a broad parallel-sided anteriorly pointed bluish area, 
humeri narrowly black. Head densely, coarsely punctate above ; 



160 ENTOMOLOGICAL NEWS [June, 1957 

antennae eleven-segmented, exceeding elytral apices by about 
three segments, basal segments sparsely ciliate internally, finely 
punctate, eleventh segment elongate, vaguely appendiculate. 
Pronotum large, a little narrower than elytra (11:12), less 
than one and one-half times as broad as long (11:8), sides 
tumid or very feebly subtuberculate, surface uneven, impressed 
on each side of disk, coarsely, shallowly, densely and somewhat 
confluently punctate, pubescence long, erect, moderately dense ; 
prosternum finely densely punctate with coarser punctures 
superimposed, densely clothed with long erect pale hairs, meso- 
and metasterna finely, densely punctate. Elytra about two and 
one-third times as long as basal width, sides subparallel, surface 
thinly clothed with moderately long suberect hairs, closely and 
rather coarsely punctate but the basal punctures distinctly 
smaller than those of pronotum, becoming finer, denser apically ; 
apices sinuate truncate, inner and outer angles distinct but not 
produced. Legs finely punctate, thinly clothed with suberect 
pale hairs. Abdomen very finely and densely punctate, clothed 
with long, pale, suberect hairs. Length, 18.5 mm. 

Holotype male (Calif. Acad. Sciences, Entom.), from Chinati 
Mt., Presidio Co., TEXAS, October 29, 1928 (E. R. Tinkham). 

This species superficially resembles those of the corallinus- 
cruentus group but may be recognized at once by the large pro- 
notum without a prominent lateral tubercle and the long pubes- 
cence of the upper and lower surfaces. The blue area of the 
elytra is unusually extensive for males in this genus. 

Amannus atriplicis Linsley, new species 

Male : Form robust ; integument black, elytra testaceous, basal 
margin and suture black, median black vitta extending from 
near apex to humerus ; pubescence dense, pale. Head rather 
finely punctate at base, clothed with moderately long, appressed 
hairs ; antennae twelve-segmented, exceeding elytral apices by 
from two to three segments, third segment a little longer than 
fourth, fourth segment subequal to fifth, segments five to eleven 
successively slightly shorter, twelfth segment distinctly shorter 
than eleventh, attenuate, segments three to seven carinate in-

ternally. Pronotum nearly one and one-third times as wide as 
long, sides obtusely rounded or subtuberculate, surface mod- 
erately coarsely, densely punctate, densely clothed with long 
appressed hairs which obscure the surface sculpture; scutellum 
densely clothed with long appressed hairs; pro-, meso-, and 
metasterna densely clothed with long, appressed pubescence 
which obscures the surface. Elytra about two and one-fourth 
times as long as basal width, finely costate; surface rather 
tate, clothed with suberect pale hairs which are a little longer 
coarsely, densely, contiguously and somewhat confluently punc- 
near base; apices rounded to suture, very slightly dehiscent. 
Legs slender; femora clothed with long appressed pubescence. 
Abdomen very densely clothed with long appressed hairs. 
Length, 10.5 mm. 

Female : Antennae not quite reaching to base of abdomen ; 
abdomen with apical margins of sternites evident but not 
broadly arcuately denuded. Length, 9-12 mm. 

Holotype male, allotype female and two paratypes, male and 
female (United States National Museum), from Presidio, 
TEXAS, May 7, 1944, on Atriplex canescens (no. 44-12184), 
collected by J. H. Russell. 

This species is related to A. vittiger Le Conte, but is a little 
larger and more robust with the elytra only about two and one- 
fourth times as long as basal width, the pubescence of the pro- 
notum appressed, rather than erect, and obscuring the surface, 
and the abdomen of the female without broadly arcuate de- 
nuded apical margins on the sternites. The elytra are margined 
with black at the base and along the suture and the median black 
vitta attains the humerus.

Eight living lice collected from a freshly killed cottontail 
rabbit, Sylvilagus audubonii (Baird), in the Great Salt Lake

Ferris 2 mentions collecting this louse "from an undetermined 
species of cottontail presumably a species of Sylvilagus . . . 
from the state of Montana," this is believed to be the first 
definite record of this association.

The Weight of Puparia of Rhagoletis basiola 
(O. S.)- (Trypetidae, Diptera) 

By W. V. BALDUF, Urbana, Illinois 
INTRODUCTION 

In a previous investigation (in press), I found that the 
puparia of this rose hip fly varied widely in length from 3.0 to 
6.9 mm. and in ratio of length to diameter from 2.00:1.00 to 
2.74:1.00. Thus, curiosity prompted me to inquire briefly also 
into the nature of their variation in weight. The 222 individ- 
uals involved here developed from larvae in the hips of Rosa 
blanda and R. Carolina near Chetek, Wisconsin. Whereas the 
hips were picked on September 5, 1950, pupariation of the 
materials concerned here occurred at Urbana, Illinois, on Sep- 
tember 17 to 22 and 26 to 28. The nine daily samples were 
weighed each day and kept separated in shell vials stored out- 
of-doors but sheltered from direct sun and rain. 

RESULTS 

The puparia were found to vary in two ways: (1) in their 
initial weights taken at the time of pupariation, i.e., within 24 
hours after the mature larvae emerged from the hips, and (2) 
in the subsequent period of 35 to 40 days during which they 
were subjected to "dry" and wet conditions, alternately. 

Original Weights. The initial weight of the 222 puparia 
totalled 3.310 grams, which gave an average value of .0149 gr. 
per individual. The nine daily samples consisted of 9 to 33 
puparia. The initial average weight per puparium for these 
samples was as follows, in chronological order: .0179 (Sept. 
17), .0166, .0155, .0159, .0133, .0145, .0167, .0141 and .0096 
(Sept. 28). These data, in general, show a tendency of the 
puparia to decrease gradually in weight from the beginning to 
the end of the over-all period of pupariation, September 17 to 
28. One condition that probably contributed to this decline was 
the deterioration of the stored hips which formed the food of 
the advanced larval instars from September 5 to 28. However, 



164 ENTOMOLOGICAL NEWS [June, 1957 

some hips remained in a well-preserved state, while others de- 
teriorated to varying extents. These differences in the condi- 
tion of the hips may well explain the chronological irregularity 
of the observed decline in weight of the puparia. 

Parasitism probably was another factor in the observed de- 
cline. The hymenopterous endoparasites, Halticoptera rosae 
Burks, Opius baldufi Mues. and 0. rosicola Mues. attacked this 
fly significantly in several years at Chetek. However, the 
present purparia were not dissected to learn the rate of inci- 
dence of the parasites, nor the manner in which they affected 
the weights of the hosts. 

Weights and Humidity. Because some puparia of all but 
two of the nine samples died in the course of the weighings, and 
because such fatalities probably prejudice the results of the 
tests, I am presenting here only the data for the two whole 
samples. Yet, the excluded samples have some informational 
value since they reflect the same general type of variations as 
the included two, namely, ( 1 ) a decided increase in weight with 
exposure to water, and (2) a marked decrease in weight under 
"dry" conditions. 

The two samples for which I have complete records involve 
56 puparia. On the days of pupariation, they were placed on 
cotton in normally dry atmosphere and weighed daily until they 
ceased to lose weight. During this period of 17 to 20 days, 
their combined initial or original weight .9404 gr., fell off to 
.6990 gr., which represents a decline of 25.67 per cent. 

Next, the dry puparia were transferred at once to a water- 
saturated wad of cotton in a vial. At the end of seven days, 
their weight had levelled off and had increased from .6990 gr. 
to .8248, i.e., 15.26 per cent. However, they still were 12.29 per 
cent short of their initial weight of .9404 gr. 

Now the puparia were again kept on air-dry cotton until the 
daily records showed their weight had again become constant. 
This condition had developed on the twelfth day, when they 
weighed .6903 gr. This figure represents a loss of 16.31 per 
cent from the previous saturated weight of .8248 gr., and of 
26.60 per cent from the initial weight of .9404 gr. 



Ixviii] ENTOMOLOGICAL NEWS 165 

DEDUCTIONS 

The observed pattern of changes suggests the following 
deductions : 

First, the living puparia have the capacity to vary sharply 
in weight, the increases noted here being due to the absorption 
of environmental water, and the decreases to the evaporation of 
body fluids through the cuticla. 

Second, the fact that the weight achieved at the termination 
of the seven-day wet period fell short, by 12.29 per cent of the 
initial weight, indicates the puparia tend to lose some of their 
capacity to regain by absorption. However, since mortality in 
puparia is not readily detected, it is possible that some of this 
loss of ability to regain all the previously lost weight was 
apparent, not real. 

Third, a change in color, texture and specific gravity accom- 
panies the variations in weight that arise from alternate wetting 
and drying. When newly pupariated, the puparia were nor- 
mally dark ocherous and rubbery, tough; when they reached 
the extreme of dryness imposed in the treatment, they had 
turned pale stramineous, rigid and fragile. The darker flexible 
condition is restored with wetting. Dry puparia float lightly on 
water; wet ones float deeply. 

Fourth, these variations in color, texture and weight, or spe- 
cific gravity, are extrinsic and inconstant, hence have only nega- 
tive taxonornic significance for segregation of species in the 
puparial stage. 



Distribution and Variation of the Ant Formica 
dakotensis Emery 

By W. L. BROWN, JR., Museum of Comparative Zoology, 

Harvard University 

Our understanding of Formica dakotensis Emery has been 
advanced considerably by Creighton (1950, Bull. Mus. Comp. 
Zool. 104: 480, 484-486) who cites data and references I need 
not repeat here. The easternmost record for dakotensis, doubted 



166 ENTOMOLOGICAL NEWS [June, 1957 

by Creighton, was based on a mixed series from Digby, Nova 
Scotia (J. Russell leg., MCZ), consisting of eight workers 
mounted on two pins. By coincidence, the top two workers on 
each pin happened to be F. subnuda Emery, the bottom two on 
each pin, F. dakotensis. Evidently Creighton saw these top 
workers only, and assumed that the pins had been misplaced in 
a group of the wrong species ; at my first glance, I also made 
the assumption that the series was homogeneous subnuda, and 
it was only after an intensive study of subnuda was begun that 
I found that instead it was a mixture of these two superficially 
similar species. There seems to be no reason any longer to 
doubt that both species occur as far east as Nova Scotia, espe- 
cially in view of the considerable range extensions that are 
reported next below for F. dakotensis. 

Variation in dakotensis includes a "race montigena," said to 
differ by having erect hairs on petiolar margin and gula. A 
series from Bluff Prairie, London, Ohio (C. H. Kennedy leg.), 
has from 3-5 erect hairs on the dorsal petiolar border ; the Nova 
Scotia specimens have 1-5 per border. 

A long series from Fairbanks, Alaska (W. Briggs leg.), is 
like the eastern lots in lacking gular hairs entirely, and generally 
has fewer on the petiolar border, often lacking hairs here com- 
pletely. The samples with both gular and petiolar hairs erect 
are found in the Colorado Rockies, Idaho, Montana, Alberta 
Rockies and British Columbia, but there is as much variation 
in series from Alberta and Montana as in the rest of the distri- 
bution combined ; some series from this region are extreme 
"typical" dakotensis, others are extreme montigena, and still 
others are intergradient and/or mixtures of the extremes. 

Since the distributional patterns of the gular hairs and the 
petiolar hairs are strongly discordant, it is obvious that they 
cannot be used together to define geographical races. Consid- 
ered alone, the gular hairs are characteristic in Colorado, but 
are less so farther north. The evidence for intergradation in 
this character alone is not quite good enough to rule out the 
possibility that montigena is a Rocky Mountain sibling that 
meets the east-west range of dakotensis in Montana and Alberta. 
The few females available do not provide very good support for 



Ixviii] ENTOMOLOGICAL NEWS 167 

this hypothesis, although the considerable variation they show 
may fall into line when better material comes into evidence. 
Everything considered, it seems likely at this time that monti- 
gena should pass into the synonymy of dakotensis; at least, the 
burden of proof should fall on those who wish to maintain mon- 
tigena as an independent taxon. 



Change of Policy on Separates 

Greatly increased production costs have finally made necessary 
a change in policy as regards separates of articles in ENTOMO- 
LOGICAL NEWS. Faced with a choice of having the printer 
almost double the prices on reprints purchased by authors, or 
of ourselves paying the costs of the 25 gratis copies furnished, 
we have decided on the latter course. We shall continue the 
old custom of accepting suitable articles from any author, and 
will publish these without cost to the author. However, the 
author will not be entitled to the usual 25 gratis separates unless 
he is a member of our Society. Every author may, of course, 
order reprints from the printer, and the prices of these are very 
reasonable considering present day costs and the high quality 
of the work. 

Anyone, whether member or not, ordering 50 or more re- 
prints will no longer receive an additional 25 copies gratis. We 
stress this detail so that authors may be informed, and will order 
the total number of reprints that they need. The cost of the 
25 heretofore added to the order is actually very small, and will 
hardly be felt by the author. Not providing them will simplify 
procedures for the printer who will then not have to bill us for 
these few extras for every author each month.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other ; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

A Japanese Weevil Abundant in the Philadelphia 

Area 

By H. W. ALLEN * - 

The Japanese weevil, Pscudocneorhinus bifasciatus Roelofs, 
appears to be increasing in numbers near Philadelphia. In 1956 
it was one of the most abundant defoliating insects in this area, 
and despite its inconspicuous nature an increasing number of 
homeowners are becoming aware of its work. 

Although injury to cultivated plants was first reported from 
Connecticut in 1924 (Britton), the earliest record of the weevil's 
occurrence in the United States is from specimens collected in 
1914 in Philadelphia but not identified until years later (Bu- 
chanan 1946). Infestations of this insect in several heavily 
populated areas of the Eastern States are discussed by Smith 
(1955). According to Buchanan (1946), it occurred in Lans- 
downe, Pa., in 1940 and in Germantown in 1944. The author 
found it present in damaging numbers at Moorestown, N. J., 
in 1946 and again in 1948 (Allen 1948). 

This weevil is distinctly polyphagous, and many host plants 
have been listed, but little has been published on its life history 
and habits. Buchanan dissected 55 specimens from Moorestown 
and found that only females were present. Smith (1955) noted 
that the beetles have fused wing covers and cannot fly, and that 
they deposit their eggs in partially eaten, curled leaves. He 
found that weevils infesting plants can be killed by application 
of dusts containing 5% of heptachlor or 2.5% of aldrin.

Observations by the author on food plants of the adult weevils 
are reported below. In the Philadelphia area privet hedges are 
commonly heavily infested and defoliated. Other plants that 
may be severely defoliated include azalea, perennial phlox, fire- 
thorn, and occasionally abelia, Japanese barberry, rose, climbing 
honeysuckle, Japanese quince, shrubby althea, forsythia, redbud, 
coralberry, hazelnut, flowering dogwood, chrysanthemum, and 
the sprouts or young plants of oak, sycamore, flowering crab, 
and walnut. Several large-leafed ornamentals not often de- 
foliated, such as rhododendron, mountain laurel, English ivy, 
and lilac, are conspicuously disfigured by the feeding of the 
weevils. Feeding has been observed also on Spirca vanhonttei, 
Euonymous radicans, coral bell, perennial veronica, geranium, 
germander, wild sweet-william, and several common weeds in- 
cluding wild aster, lamb's-quarters, Pcrsicarea, and northern 
bugleweed. 

In 1956 a few adults were found on June 9. Thereafter they 
were observed frequently throughout the season until after the 
first heavy frosts. The peak of abundance was in late July, 
but beetles were still plentiful in late September, and feeding 
continued throughout that period. Early in August one side of 
a section of moderately infested privet hedge about 3 feet high 
was jarred over a 90-inch length of sheeting and 70 beetles were 
knocked down. On September 26, 170 beetles were collected in 
a few minutes from about 60 feet of azalea and privet, but on 
October 12 only one could be found on the same shrubs. In an 
indoor cage at room temperatures nearly all these beetles were 
alive and vigorous on October 25. 

Although samples of soil from beneath heavily infested bushes 
and around the roots and crowns of adjacent weeds and grasses 
were examined several times between June and October, no 
larvae or pupae were found. Egg pods were found first on 
September 21, but may have been present earlier, since well- 
developed ovarian eggs were found in 2 of 20 females on August 
2, and 14 of 20 on August 23. Among beetles collected on 
September 26 maximum oviposition occurred from September 
28 to October 9. There seems to be no diapause in the egg 



Ixviii] ENTOMOLOGICAL NEWS 171 

stage. By October 22 nearly all the eggs deposited from Sep- 
tember 27 to 30 and kept at room temperatures had hatched. 
October hatching also occurred among eggs kept in an outdoor 
insectary. In late October one newly hatched larva was found 
in the soil beneath heavily infested privet. However, eggs de- 
posited early in the month and bedded in dead leaves in the 
shade had not hatched by October 22. It appears that this 
insect starts hibernation in the egg stage, and also as small 
larvae in the soil. 

The adult (Fig. 1 ) is a robust, brownish-gray weevil, 4.5 to 
7 mm. long, with two broad, transverse black bands across the 
elytra. The snout is broad and only slightly longer than wide. 
Adults are sluggish and unable to fly ; hence their dissemination 
must be chiefly by transport. Of 42 dissected during July and 
August none had membranous wings and all were females. No 
males have yet been found. 

The adults are usually found in shaded areas. They frequent 
the foliage and twigs of host plants and the ground beneath them. 
They are present on foliage both day and night, and on both 
fair and rainy days. They may remain quiescent for long pe- 
riods in the angle between leaf petioles and the stem of a twig, 
where they resemble axillary buds. They feed at the edge of 
the leaf, cutting out small sinuses and sometimes giving it a 
ragged, coarsely serrate appearance. Feeding continues from 
June to October, and may cause nearly complete defoliation by 
late summer. The beetles have a tendency to form clusters, and 
bunches of 3 to 20 may be seen on heavily infested plants. De- 
foliation is always progressively less from the ground level 
upward, and heavy feeding is not often found more than 6 feet 
from the ground. When there are many beetles feeding on a 
bush, the leaves below them are usually spotted with black, 
adhesive, more or less cylindrical fragments of excrement. 

When infested shrubs are slightly jarred, most of the beetles 
drop to the ground, and some will drop when the shadow of a 
hand passes quickly before them. Beetles that have dropped to 
the ground are inactive for a minute or two, when they may be 
rolled about like small pellets of earth, but they soon regain 
activity and crawl away. 



172 ENTOMOLOGICAL NEWS [J u ty> 1957 

When the egg is first laid it is white, with a thin, translucent, 
flexible, unsculptured shell. It is about 1.1 mm. long by 0.35 
mm. wide, and slightly enlarged at the posterior end. As the 
embryo develops, the egg becomes creamy yellow, and the light- 
brown mandibles of the larva are visible through the shell. 

The eggs are usually deposited in inconspicuous folds at the 
margins of dead leaves or leaf fragments, but some have been 
found over the midrib near the petiole, and a few eggs have been 
found on green leaves. The free edge of the fold is sealed to 
the basal portion of the leaf fragment, enclosing the eggs like 
seeds in a pod. There may be one to eight eggs in a fold. In 
the natural habitat a few egg pods were found in the dead mar- 
gins of leaves on azalea and lilac bushes. Several more were 
found in scattered leaf fragments under a privet hedge nearly 
free of trashy mulch, and others were located by diligent search 
in the copious leafy trash under infested rose and azalea. Caged 
beetles deposited eggs more freely in leaf fragments on the 
ground than in leaves or leaf fragments attached to the twigs 
in the feeding area, and this condition is probably true in the 
natural habitat. Of a total of 168 egg clusters deposited by 
caged beetles, 72% were found in the leafy debris on the ground. 

Newly hatched larvae are creamy yellow with light-brown 
heads. They are footless, with long, sparse pubescence. On 
hatching they crawl from the egg pods, drop to the ground, 
crawl an inch or less over the surface, enter some depression, 
and quickly burrow into the soil. In a cage at room tempera- 
ture several young larvae that were more than twice the size 
of the eggs were found in moist soil containing pieces of lilac 
roots. There seems to be little doubt that the larval stage de- 
velops in the soil under or close to the plant where the egg pods 
were deposited. 

Moderate to heavy feeding on ornamentals by P. bifasciatus 
adults was observed in 1956 in Mt. Holly, Burlington, Moores- 
town, Maple Shade, Merchantville, Haddonfield, Palmyra, 
Riverton, Runnemede, Woodbury, Paulsboro, Williamstown, 
and Hammonton, N. J. ; Langhorne, Bustleton, Germantown, 
Chestnut Hill, Whitemarsh, Conshohocken, and Phoenixville,

Pa. These towns enclose an urban area of about 900 square 
miles. Infestation is apparent chiefly in built-up residential 
sections, particularly where there are well-shaded gardens bor- 
dered by shrubs and perennial plantings or by hedges. This 
area includes almost completely urban Philadelphia and Cam- 
den, and scores of towns, villages, and residential developments 
where the weevil thrives. It also includes more sparsely popu- 
lated countryside where weevils are absent or not easily found. 
In nearly all the towns listed above, more than half the privet 
hedges were found to be moderately to heavily infested. In 
Moorestown, N. J., interspersed among the many infested prop- 
erties were gardens in which no beetles could be found. There 
were even hedges with practically no evidence of weevil injury 
directly across the street from heavily infested hedges.

Most students take but one course in entomology. If this has 
to be one in applied entomology, we have here a book that will 
serve well as a text. It includes 35 pages of anatomy and physi- 
ology, and about that many on the principles of control ; the rest 
is chiefly classification and biology. Each order has keys to 
principal families, and under each family one or more species is 
taken up in detail. When a family contains economic insects it 
is these that are chosen, and all the commoner pests receive ade- 
quate attention, each under its proper order and family. 

In some applied texts, one studies in succession the pests of 
corn, cotton, etc., etc. ; one never, for example, takes up aphids 
as aphids, since they are scattered about in the book under their 
host plants, and juxtaposed to entirely unrelated insects, which 
seems, somehow, a curious way to study entomology. Is this

On the Removal of Certain New World Genera 

from the Decticinae to the Listroscelinae 

(Orthoptera; Tettigoniidae) 

By JAMES A. G. REHN, Curator of Insects, Academy of 
Natural Sciences of Philadelphia 

In 1900 the present author described a very unusual species 
of tettigoniid from the hot Rio Balsas valley of Guerrero, Mex- 
ico, as a new species (impcrfectus) of the genus Capnobotes, 1 
which latter was then and has since been consistently referred 
to the subfamily Decticinae. The other species of Capnobotes 
were then, and are yet, considered to be limited to the south- 
western United States, but they undoubtedly also occur in arid 
northwestern Mexico. In 1901, after study of material of true 
Capnobotes not previously available, the author erected the new 
genus Ncobarrettia for the species Capnobotes imperfectus, 2 
dedicating it to the collector of the original material, Otis W. 
Barrett. In 1907, my friend and colleague, Mr. A. N. Caudell, 
in a revision of the North American Decticinae, established the 
genus Relmia, 3 assigning to it two new species, R. victoriae, 
from Victoria, Guerrero, Mexico, and R. spinosa, from Texas. 
We now know victoriac from a relatively broad range of locali- 
ties extending northward as far as Kansas, and spinosa con- 
versely extending down into eastern Mexico. Two species have 
been added subsequently to Rchnia R. cerberus Rehn and 
Hebard, from western Texas, and R. sinaloae Rehn and Hebard, 
from Sinaloa, Mexico. 4 

For some years past I have had the impression that both 
Neobarrettia and Rchnia were misplaced in the Decticinae, but 
only recently has it been possible for me to make the needed 
series of comparisons to prove or disprove this belief. It is now 
possible to say definitely that both genera do not belong to the 
Decticinae, but are instead members of the Listroscelinae, an

otherwise chiefly pan-tropical subfamily very well developed in 
South America. 

The evidence for this conclusion has been drawn from the 
following structural features of the two genera, which fully agree 
with what we find in other representative genera of the Listro- 
scelinae, and accordingly disagree with typical members of the 
Decticinae : ( 1 ) the very narrow, strongly and lamellately com- 
pressed fastigium; (2) the general structural pattern of the 
pronotum ; (3) the strongly developed and paired spiniform 
processes on the prosternum, mesosternum and metasternum, 
not just on one or the other element, but on all; (4) the dis- 
tinctly tuberculate or subspiniform process found on the internal 
surface of the coxae, particularly of the median and caudal 
limbs; (5) the well spined character of both of the ventral 
margins of the cephalic and median femora, and the relatively 
marked development of the spines on the ventral margins of the 
corresponding tibiae ; and (6) the relative expansion and de- 
planation of the ventral surfaces of the cephalic and median 
femora, the latter a condition strongly developed in Listroscelis 
and other members of the subfamily. 

The criteria used in the past for the separation of the sub- 
families of the Tettigoniidae have frequently been the presence 
or absence of certain limb spines, which, increasingly, we know 
are of less diagnostic value than long supposed. For instance, 
the presence of a disto-dorsal spine on the external (caudal) 
margin of the cephalic tibiae often has been given much weight. 
In twenty-nine specimens of Ncobarrcttia imperjecta I find this 
spine present in twenty-eight, but in one individual curiously 
it is absent from the external margin but has shifted to the other- 
wise unspined internal (cephalic) margin. In fourteen indi- 
viduals of Rehnia sinaloac this spine is present on both cephalic 
tibiae in all but one, in which it is present on one limb and 
absent from the other. In sixty specimens of Rehnia victoriae 
this spine is present on both cephalic tibiae. Absence can be a 
matter of early injury, hence have a teratological background. 
Thus it is increasingly desirable that morphological features of 
more fundamental character be found and utilized to define 
generic or suprageneric categories.

It is quite evident that Rehnia and Neobarrettia are closer to 
some of the Neotropical genera of the Listroscelinae with which 
they have been compared, such as Arachnoscclis, than they are 
to the more divergent lines represented in tropical America by 
Phlugis, and in the Old World tropics and subtropics by 
Xiphidiopsis. 

The removal of Neobarrettia and Rehnia from the Decticinae 
to the Listroscelinae is here made only after a comparative study 
of all the North American genera of the former subfamily and 
a considerable number of the extra-limital ones. Except where 
the Sonoran element penetrates into northern Mexico I know 
of no unquestioned decticines from the whole of America south 
of the United States. The present investigation carries the 
Listroscelinae definitely into North America as usually defined 
politically. I believe Neobarrettia and Rehnia represent a rela- 
tively early invasion of our territory from a more southern 
center of the subfamily, and that they have developed individu- 
ally in their respective areas of arid or semi-arid conditions. 
The Rio Balsas valley, the home of Neobarrettia, is regarded by 
meteorologists as the hottest area of Central America. 



Redescriptions of Ewing's Oribatid Mites, IV 

Family Achipteriidae (= Notaspididae)

This article is another in the series which deals with rede- 
scriptions of Ewing's type species of oribatid mites. Pencil 
drawings were prepared by Dr. E. W. Baker of the U. S. 
National Museum and made available to the writer. Acknowl- 
edgment of the drawings is indicated by the initials on the 
finished plates. Ewing's original descriptions are followed as 
closely as possible, but modern acarological terms are substituted 
where necessary. The article is presented in somewhat cursory

fashion since it is the intention of the writer to incorporate 
details later in a review or revision of the family. 

FAMILY ACHIPTERIIDAE VAN DEN HAMMEN, 1952 
(= NOTASPIDIDAE OUDEMANS, 1900) 

The anteriorly projecting cusps on the pteromorphae and the 
broad, medially-fused lamellae are the principal characteristics 
of this family of pterogasterine mites. 

Both Grandjean (1936) and van der Hammen (1952) con- 
clude that the name Notaspis is improperly used in this family 
since the generic designation as originally indicated by Hermann 
(1804) is applicable to eleven different mites. Accordings to 
the former authors the genus Achipteria Berlese, 1885, more 
properly designates the type genus in this family, and is char- 
acterized by slit-like pores on the dorsum of the hysterosoma. 

This paper deals principally with two species in the genus 
Achipteria which were described by Ewing (1918) from collec- 
tions in Oregon. In other publications (1909, 1910) he dis- 
cusses several species of Notaspis. In this paper the writer 
proposes changes in the generic designations of these species 
and discusses their taxonomic relationships. 

Achipteria oregonensis Ewing, 1918. (Figs. 1, 2) 

Description: Cotype broken on left side of hysterosoma. Dark 
brown. Lamellae broad at base, completely obscuring rostrum 
and other aspects of propodosoma ; each lamella with incurved 
antero-lateral margin and blunt tip, sclerotized medial margins 
from insertions of lamellar hairs to base of lamellae ; a narrow 
U-shaped cleft between anterior half of sclerotized medial mar- 
gins of lamellae, cleft extending from insertions of lamellar hairs 
half the distance to hysterosoma. Lamellar hairs about as long 
as widest width of lamellae, extended from insertions beyond 
anterior tip of lamellae, minutely pectinate and curved laterally 
at tips. Translamella a brief sclerotized bar at posterior margin 
of U-shaped cleft between lamellae. Interlamellar hairs barbed 
along entire length, about as long as lamellae, inserted close to 



Ixviii] ENTOMOLOGICAL NEWS 179 

mesal edge of lamellae near anterior margin of hysterosoma, 
incurved at tips. Pseudostigmata deep, cup-like, in notch 
formed by latero-posterior margin of lamellae and curved medial 
bases of pteromorphae. Pseudostigmatic organs three-fourths 
as long as cusp of pteromorph, somewhat fusiform, with minute 
spines, projected forward between lamellae and pteromorphae. 

Surface of hysterosoma smooth (broken on left side in cotype 
specimen), broadly oval in outline with angular shoulders and 
rounded posterior margin. Each pteromorph with an anterior 
cusp; cusp projecting forward, outward and downward at distal 
tip, about two-thirds as long as lamella, not reaching level of 
anterior margin of propodosoma. A single, simple dorsal bristle 
directly posterior to inner proximal margin of pteromorphal 
cusp, inserted its length posterior to hysterosomal margin ; an- 
other simple bristle near latero-posterior margin of pteromorph. 
Other bristles and glandular fissures as shown in Fig. 1. 

Camerostome broadly oval. Ventral plate distorted and 
broken in cotype specimen. Setae of ventral plate and apode- 
mata as seen in Fig. 2. Genital opening nearly square, about 
two-thirds as large as anal opening; genital covers with 7 pairs 
of setae ; g : 1 and g : 2 inserted in anterior margin of each cover ; 
g:3, g:4, g:5, g:6 inserted in a longitudinal row in middle of 
cover ; g : 7 inserted mediad of this row and near posterior mar- 
gin of cover. Anal aperture about twice as large as genital 
opening, each anal cover trapezoidal in outline and with two 
setae. Insertions of anal and adanal setae as in Fig. 2. 

Legs described by Ewing (1918) as long and heterodactyle. 

Length 771 //,, hysterosoma 614 /x; width 530 /A. 

Several specimens were collected by H. E. Ewing from the 
ground beneath an old piece of wood at Corvallis, Oregon. 

Achipteria borealis Ewing, 1918, nov. comb. (Figs. 3, 4) 
Type : Achipteria oregonensis var. borealis Ewing, 1918, p. 84. 

Description: Lamellae broad at base, tapered to a sharp point 
anteriorly, a deep V-shaped cleft between anterior tips and 
extending nearly half the distance to base of lamellae ; medial 



180 ENTOMOLOGICAL NEWS [July, 1957 

margins sclerotized from insertions of lamellar hairs posteriorly, 
where lamellae are separated slightly anterior to hysterosomal 
margin. Lamellar hairs simple, stouter than interlamellar hairs, 
projected slightly beyond anterior points of lamellae, inserted 
their lengths from anterior ends of lamellae in frontal tip of 
sclerotized medial margin. Interlamellar hairs nearly as long as 
lamellae, fine, simple, inserted in meso-posterior margin of 
lamellae, distal tips curved inward. Pseudostigmata cornuate 
beneath surface of hysterosoma at base of lamellae. Pseudostig- 
matic organs not seen. 

Hysterosoma smooth, broadly oval ; pteromorphae extended 
nearly two-thirds the length of lateral margin ; anterior cusps 
nearly straight, projected forward about half the length of 
lamellae. Six pairs of setal insertions and two pairs of glandular 
fissures as shown in Fig. 3. 

Details of ventral aspect obscured by dark color of specimen 
except for those shown in Fig. 4. Tectopedia I similar to the 
same structure in A. oregonensis , but ribbed on lateral margins. 
Genital and anal apertures as figured; genital and anal setae 
not visible. 

Length 571 /*, hysterosoma 470 /A; width 356 /t. 

Ewing (1918) collected a single specimen of this species 
under a rotting log at the top of Mary's Peak, Oregon. 

Discussion: Ewing's original description (1918) of Achipteria, 
oregonensis is accompanied by a single text-figure of the right 
pteromorphal cusp of one of the cotypes from Corvallis, Oregon. 
As originally described A. borealis differs in size and shape of 
the pteromorphal cusp. Further differences are noted, however, 
in the sclerotization of the lamellae and pteromorphae; in the 
lengths of lamellar and interlamellar hairs, which are stout and 
pectinate in A. oregonensis and simple in A. borealis; in the 
relative size of the two species, A. borealis is the smaller of the 
two. Ewing (1918) used the pteromorphal cusp to distinguish 
his described variety from the species. These other marked 
differences, however, are sufficient to justify the elevation of 
the variety to specific rank, in the opinion of the writer. 

Both A, oregonensis and A. borealis differ from the known 
European species and from the Canadian species, A. nivalis

Hammer, 1952, in size and arrangement of lamellae, lamellar 
and interlamellar hairs. 

Ewing (1909) describes other species of Notaspis which 
should be discussed. All cotypes of one of these, Notaspis tex- 
ana Ewing, 1909, are smashed. The writer has drawn part of 
the propodosoma and the leg of one of these cotypes (Figs. 5, 6). 
The lamellae, pseudostigmata and interlamellar hairs indicate 
that this species is definitely not Notaspis nor Achipteria. It 
probably belongs in the genus Zygoribatula, but the condition 
of the specimens makes final determination impossible. 

Notaspis brevirostris Ewing, 1910, and Notaspis depilis 
Ewing, 1909, also are species of indeterminate position. Neither 
appears to belong to Achipteria. The former is illustrated by a 
photograph which is not detailed enough to allow critical diag- 
nosis. Analysis of the verbal description, in which there is no 
mention of pteromorphae, indicates that it is definitely not a 
species of Achipteria. The lamellae are short with free cusps, 
also in contradistinction to the large plates typical of Achipteria. 
Furthermore, the genital and anal apertures are nearly con- 
tiguous, a condition which is not characteristic of this genus. 
Notaspis depilis is much more characteristic of the genus Zygori- 
batula. In the opinion of the writer, these facts constitute suf- 
ficient justification to infer taxonomic misplacement of these 
two species. Their exact designation cannot be determined, 
however, until all of the specimens can be examined and com- 
pared with known species.

New Oak-Inhabiting Species of Erythroneura from 
Illinois (Hemiptera, Cicadellidae) 

By HERBERT H. Ross, Illinois Natural History 
Survey, Urbana 

Among the oak-inhabiting species of Erythroneura found in 
Illinois, those with a rigid restriction to shingle oak (Quercus 
imbricaria} and the black oaks (Quercus nigra group) are prov- 
ing to have been the least understood. This situation is due to 
the relatively infrequent occasions when the collector encounters 
large populations of Erythroneura on these hosts. By good 
fortune, in the last two years we have found a few groves of 
these oaks having moderate to large leafhopper populations. 
On the basis of the large numbers of individuals thus available 
for study, it is now apparent that certain observed structural 
differences, previously suspected of being only variations of one 
or two species, in reality demark distinctive species segregates. 
It is these species which are described in this paper. 

ERYTHRONEURA LENTA complex 

In Erythroneura lenta and its immediate allies the body 
markings are scattered red bars and dots on a pale background, 
typical for the great majority of species in the maculata group; 
the style has either no posterior point or a minute one; the 
aedeagus is simple, deeper than thick ; and the pygofer hooks are 
slender and either nearly straight, curved, or only moderately 
sinuate. To this complex belong lenta Beamer, longa Knull, 
patris Ross and DeLong, and several other species, some of 
them apparently undescribed. 

Erythroneura marilandicae new species 

Most closely related to longa, this species may be distinguished 
by the shorter, tapering shaft of the aedeagus and the more 
curved dorsal aspect of the pygofer hooks. In longa the latter 
are almost straight. 



184 ENTOMOLOGICAL NEWS [July, 1957 

Color and general structure as in typically spotted members 
of the lento, complex. Male genitalia as in Fig. 1. Pygofer 
hook slender, extending considerably beyond pygofer 5 the latter 
aspect slightly curved ventrad, the dorsal aspect bowed, the two 
hooks converging toward apex. Style without posterior point 
(as in Fig. 3). Aedeagus with curved internal apodeme; 
phalicata short, straight, and slightly tapering, lateral aspect 
only moderately deep, ventral aspect narrow.

Erythroneura econa new species 

Based on general proportions of aedeagus and pygofer hooks, 
this species also is most closely related to longa, but differs in 
that the pygofer hooks diverge at apex and have an apparent 
twist to the apical portion, Fig. 2A, B, resulting in the apical 
half being abruptly narrowed in dorsal view. 

Color and general structure as for typically spotted members 
of lenta complex. Male genitalia as in Fig. 2. Pygofer process 
extending just beyond apex of pygofer; in lateral view the base 
is narrow and the apical half is slightly wider (in some speci- 
mens this enlargement is not seen until the abdomen is rotated 
a few degrees from a strictly lateral position) ; in dorsal view 
the base is relatively thick and the apical half is abruptly thinner. 
Style without posterior point. Aedeagus with short, straight 
internal apodeme ; shaft slender, moderately long, and almost 
straight.

Erythroneura metopia new species 

The ventrally-curved pygofer hook indicates a close relation- 
ship between this species and patris, from which metopia can be 
diagnosed by the angulate rather than gently curved pygofer 
hook and the very short aedeagal shaft. 

Color and general structure typical for the lenta complex. 
Male genitalia as in Fig. 3. Pygofer hook slender, extending to 
end of pygofer and bent relatively sharply ventrad at midpoint ; 
the two hooks, seen from dorsal view, converge slightly toward 
apex. Style without posterior point. Aedeagus with short in- 
ternal apodeme ; shaft unusually short for the complex, tapering 
and both shallow and narrow.

Erythroneura alicia new species 

On the basis of genitalic structures this species is closest to 
longa and marilandicae, from both of which it differs in the 
more sinuate pygofer hooks and sinuate aedeagal shaft. From 
all members of the lenta complex alicia differs in possessing 
three pink transverse bands across the dorsum, in position like 
the darker bands of tnvittata. 

Color pale with three transverse pink bands across the folded 
tegmina, one at the base including also the scutellum, one across 
the middle, and the third slightly before the apex. General 
structure typical for complex. Male genitalia as in Fig. 4. 
Pygofer hook slender and tapering, extending slightly beyond 
apex of pygofer, moderately sinuate from either lateral or dorsal 
view. Style without posterior point. Aedeagus with short 
internal apodeme; shaft short, only moderately deep, its lateral 
aspect definitely sinuate, its ventral aspect narrow.

ERYTHRONEURA TRIVITTATA complex 

Two previously described species, confirmata McAtee and 
trivittata Robinson, form a distinctive small complex in which 
the style has both a posterior and anterior point, both slender 
and pointed, Fig. 5E. In confirmata the dorsal aspect (with 
wings folded) has an exquisite red saddle-like pattern, whereas 
in trivittata the dorsal aspect has a light ground color crossed 
by three nearly black transverse bands. Previously this banded 
pattern was considered diagnostic for the species trivittata, but 
we have discovered two additional species described below 
possessing this pattern. Shingle oak is the host for all four 
species of the complex. 

Erythroneura amethica new species 

This and the following species are close relatives of trivittata 
Robinson, possessing in common with it three conspicuous trans- 
verse red and black bands across the tegmina. E. amethica 
differs from the other two banded species in the shape of the 
pygofer hooks, which converge at the apex. 

Male genitalia as in Fig. 5. Pygofer hook elongate, of nearly 
uniform thickness to near curved apex ; dorsal aspect gently 
sinuate. Style with sharp anterior point and sharp, narrow 
posterior point. Aedeagus with base unusually large ; phalicata 
nearly cylindrical, the apical half and most of the ventral margin 
spiculate ; ventral aspect slightly irregular.

of Erythroneura in possessing a sickle-shaped style, much as in 
Fig. 7E. Two closely related species are here described, bring- 
ing to three the number of known species possessing this 
character.

The Synonymy of Two Species of North American 

Chrysis, sens. str. (Hymenoptera, 

Chrysididae) 

By KARL V. KROMBEIN, Entomology Research Branch, 

United States Department of Agriculture, 

Washington, D. C. 

The synonymy proposed below is a result of a recent com- 
parison of the types of several species of typical Chrysis de- 
scribed by Viereck and by Rohwer with those described by 
Aaron in the Academy of Natural Sciences of Philadelphia. 

Chrysis (Chrysis) pattoni Aaron 

Chr\sis Pattoni Aaron, 1885. Trans. Amer. Ent. Soc. 12 : 235. 
Chrysis (Tetrachrysis) decepta Rohwer, 1909. Psyche 16: 90. 
NEW SYNONYMY. 

The unique type of decepta, a female from Boulder, Colorado, 
in the U. S. National Museum, is extremely similar to the 
unique type of pattoni, a female from Colorado, differing in 
only a few details of infraspecific importance. The type of 
pattoni has the facial carina a little weaker and not so curved 
downward in middle, head in frontal view but quite so strongly 
arched above, and small area immediately basad of median 
apical emargination of third tergum flatter. 

Chrysis (Chrysis) propria Aaron 

Chrysis propria Aaron, 1885. Trans. Amer. Ent. Soc. 12: 238. 
Chrysis (Tetrachrysis) kahli Viereck, 1906. Trans. Amer. Ent. 

Soc. 32: 194. NEW SYNONYMY. 
Chrysis (Tetrachrysis) pattonclla Viereck, 1906. Trans. Amer. 

Ent. Soc. 32: 194. NEW SYNONYMY. 

The unique male type of kahli from Kansas and of pattonclla 
from Hamilton County, Kansas, both in the University of Kan- 
sas collection, are very similar to each other in details of the 
sculpture and vestiture. They differ in color, that of kahli being 
blue, while that of pattonclla is green. Both agree very well in 



192 ENTOMOLOGICAL NEWS [July, 1957 

all details of sculpture with the male lectotype (selected by 
Cresson) of propria from Montana. 

The type series of propria is a mixed one, and includes repre- 
sentatives of at least two and possibly three species. Four of 
the available paratypes are females, and two are males (the 
original type series consisted of eight specimens). 

One male and two females from Montana and one female 
from Colorado are conspecific with the lectotype. A male from 
California is perhaps different the facial carina is absent, the 
head and thorax are not so closely punctate, and the apical teeth 
of third tergum are shorter. The female from Arizona is cer- 
tainly a distinct species it is the only member of the type series 
having the pronotum longer than the head (shorter than the 
head in the others ) , and the pronotal punctures are much larger 
and the median pronotal groove extends almost to the posterior 
margin. 

I am indebted to G. W. Byers of the Department of Entomol- 
ogy, University of Kansas, for making available the types of 
typical Chrysis described by Viereck.

method really so "practical?" Every farmer and grower knows 
his pests, and his local store will provide the latest insecticide 
with full instructions. It is when a new insect appears, or when 
one has a plant not in the book, or one is confronted with some 
other novel situation that one must draw on whatever general 
knowledge and understanding of insects that one may have. This 
fundamental (often called theoretical or impractical) knowledge 
then turns out to be the truly useful, and can be applied to the 
specific situation. 

This book, with its truly entomological approach, is a valuable 
addition to our list of applied text-books ; it represents a return 
to the method of the renowned John B. Smith's "Economic En- 
tomology" of a past generation. It is hoped that it will be fol- 
lowed by other editions, or other applied texts, in which, in fair- 
ness to the student, still more general entomology is set forth, 
including, particularly, more of the general ecological side of 
insect life. R. G. SCHMIEDER.

Chalcidoid Wasps (Eulophidae, Eurytomidae) 

Reared from the Bullet Gall Caused by 

Disholcaspis mamma (Cresson) 

(Cynipidae) 

By W. W. JUDD, Department of Zoology, University of 
Western Ontario, London, Ontario 

On March 31, 1956, several galls were collected from twigs 
on a sapling of Bur Oak, Quercus macrocarpa, in a copse of 
hardwood trees on the north shore of Fanshawe Lake in London 
Township, Middlesex County, Ontario. The galls were in three 
clusters on the twigs with 11, 3 and 7 galls, respectively, in the 
three clusters. They were identified with keys in Felt (1940) 
as the Rough Bullet Gall caused by the cynipid wasp Dishol- 
caspis mamma (Cresson). This species is included as a gall- 
maker on Q. macrocarpa by Muesebeck et al. (1951). Most of 
the galls were about 1.5 cm. in diameter, a few of them being 
smaller than this. When the galls were dissected after the 
rearing of insects from them had been completed it was found 
that each gall consisted of a solid, woody exterior wall about 
5 mm. thick and, within this, a separable central capsule with a 
tough, thin wall. This capsule could be rolled out of the gall 
intact and resembled a small, yellow pea 4 mm. in diameter. 
The capsule from one of the galls, opened on the day of the 
collection, contained 26 small, white hymenopterous larvae. 
Only one gall showed an emergence hole, 1.5 mm. in diameter. 

Each of the remaining 20 intact galls was placed in a cotton- 
plugged vial of dimensions 60 mm. X 15 mm. and kept on a 
rack in a laboratory. Each day the vials were examined for the 
presence of emerged insects and these were pinned and labelled 
or preserved in fluid. On January 31, 1957, the galls were split 
open and insects remaining in them were removed. Of the 20 
galls, 4 yielded adults of the wasp Eurytoma querci-globuli 
(Fitch), 1 showed an emergence hole perhaps made by E. 
querci-globuli, 9 yielded adult wasps, Tetrastichus phegus Burks, 
3 contained molded contents in their capsules and 3 were small

National Museum. 



EULOPHIDAE 
Tetrastichus phegus Burks 

Nine of the galls yielded 65 male (367c) and 117 female 
(64%) T. phegus. Many of these emerged from six of the 
galls between May 30 and June 5 (Table 1) and the remainder 
were found in three galls when they were dissected. The wasps 
emerged from the galls through circular holes in the wall 0.7 
mm. in diameter. In some galls all the wasps emerged from a 
single hole in the gall and in other galls from two or three holes. 
Those wasps which failed to emerge from three of the galls 



Ixviii] ENTOMOLOGICAL NEWS 195 

were found dead in the central capsule of one gall and jammed 
between the wall of the capsule and the solid exterior wall in 
two galls. The distribution of sexes of the wasps from each of 
the nine galls was as follows: (lljtf, 13??), (1 33, 14??), 
(19 eta 18?$), (8^, 11??), (9c?<T, 12??), (6 cJtf, 14??), 
(14??), (9J^, 13??), (2 &?, 8??). T. phegus is a wasp 
described by Burks (1943) from specimens reared from cynipid 
galls of the genera Disholcaspis and Heteroecus, including para- 
types from D. mamma. 

EURYTOMIDAE 

Eurytoma querci-globuli (Fitch) 

Four female E. querci-globuli emerged from four galls be- 
tween June 18 and July 3 (Table 1), after T. phegus had ceased 
emerging, and no gall yielded these two species. E. querci- 
globuli emerged through a circular hole 1.5 mm. in diameter in 
the wall of the gall. In addition one gall, examined on the day 
of collection, showed an emergence hole of the same diameter. 
E. querci-globuli is included by Muesebeck ct al. (1951) as a 
parasite of galls of the genus Disholcaspis. 

ACKNOWLEDGMENT

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

Some Psocoptera from Tikal, Guatemala 

By EDWARD L. MOCKFORD, Illinois Natural History Survey, 

Urbana, Illinois 

The psocids discussed in this paper were collected at Tikal, 
Department of Peten, Guatemala, in late winter and spring of 
1956 by Dr. Irving J. Cantrall of the University of Michigan 
Museum of Zoology, Ann Arbor. The material consists of 
seven specimens representing seven species, seven genera, and 
four families. Five of the species are new and are described 
below ; the other two may be new. To my knowledge, these 
are the first published records of Guatemalan psocids. The 
meagre information on psocids of Central America in general 
suggests that a very rich fauna must exist in that region. 

Two genera used in this paper have not previously appeared 
in the New World literature. The genus Ghesquierella Badon- 
nel is based on African material, but the similarities between 
the Guatemalan species and the African genotype are sufficiently 
striking to indicate a probable close relationship. The genus 
Psoddus Pearman was erected to include all forms in the Psoci- 
dae which cannot be placed in one of the existing genera. Until 
the relationships of such forms become better understood, it 
seems advisable to continue using Psoddus in this way rather 
than to erect new genera. 

FAMILY PTILONEURIDAE 
Loneura splendida new species ($) 

Diagnosis: Near L. brasilicnsis Roesler, differing in the fol- 
lowing forewing characters: cell R 2 + 3 proportionally much

to that of L. brasiliensis, the chief differences being in forewing, 
where Rs from the point where it leaves r-m crossvein to the 
point where it forks proportionally much shorter than in L. 
brasiliensis, whereas radial fork proportionally much longer ; 
vein M- branched in right wing, the anterior branch rebranching 
in left wing. Subgenital plate with rounded posterior margin ; 
pigmented area of subgenital plate in form of a broad U, ends 
of which are curved outward. Gonapophyses (Fig. 7) : first 
valvula slender, about three-quarters length of second valvula,

forewing from vein M 3 to R 4 + r ,, in contrast to a marginal band 
in T. inagnifica Roesler, T. refle.va Roesler, and T. margine- 
picta Roesler, and no band in T. lucida Roesler and T. dolosa 
Roesler. Curvature of veins in forewing most similar to that 
of T. refle.va, but differing in the marked flexure of R 2 + 3 , M 2 ,

Ghesquierella cantralli new species 

Diagnosis: Agrees with genotype, G. calcnsis Bad., in struc- 
ture of the hypandrium, shape of forewing and of most of its 
cells (notable exceptions being the narrower, bent cell R 2 + 3 and 
narrower An in G. cantralli), presence of a mark below ptero- 
stigma and another below that in cell R-, and pattern of dark- 
bordered veins in forewing. Differs from the genotype in pos- 
sessing a pair of spiny lateral areas on hypandrium, a fumose 
basal portion of forewing, and in shape of the apex of the 
phallic frame. In forewing, vein Sc joins radial stem in G. 
cantralli but not in G. calcnsis. 

Measurements: Total body length 3.36 mm. : forewing length 
4.93 mm. ; hindwing length 3.60 mm. ; posterior tibia length 2.04 
mm. ; posterior tarsus T, 0.57 mm., T, 0.24 mm. 

Morphology: Compound eyes small; IO/D = 2.33, PO/D = 
0.90. Ocellar interval not prominent. Anterior ocellus smaller

than posteriors. Antennae clothed in rather long, curved hairs. 
First flagellar segment with two discoid sensillae near its base. 
Antennae broken off, but probably much longer than forewing 
as right antenna to basal part of f. t equals length of forewing. 
Distribution of tarsal ctenidia : none on anterior tarsus ; middle 
tarsus T, 15, T 2 4; posterior tarsus 1\ 23, T 2 5. Wing 
venation (Figs. 13 and 14) much as in the genotype, differing 
as indicated in the diagnosis. Hypandrium (Fig. 15) nearly 
symmetrical, produced apically into a central lobe bordered on 
each side by a row of spines, and a spiny lobe on each side. 
Phallic frame as in Fig. 6, its apex shaped somewhat as in 
Psococerastis. Paraprocts each with a large sensory area about 
midway between base and apex, and a slightly curved apical 
process (Fig. 19). 

Color (in alcohol) : Compound eyes, inner rims of ocelli, 
flagella, and distal two segments of maxillary palpi black. Body 
generally orange. Legs straw colored basally, becoming nearly 
black on tarsi. Forewings fumose basally, hyaline apically ex- 
cept for dark borders of veins and two spots below pterostigma ; 
pterostigma orange. Hindwings hyaline except for faintly 
fumose anal cell. 

Type locality: GUATEMALA: Department of Peten, Tikal. 
February 14, 1956, I. J. Cantrall collector. The type is in 
my collection. 

Metylophorus sp. 

A single male was taken April 6, 1956. It is very similar to 
M. novaescotiae (Walker), a species common throughout East- 
ern U. S. The only differences noted were the slightly smaller 
body size and proportionally much larger size of the compound 
eyes of the Guatemalan form. There may be differences in the 
numbers of teeth on the hypandrial ridges, but the extent of 
variation in these numbers in M. novaescotiae is not known. 
These differences may prove to be clinal or subspecific when 
additional material becomes available.

A New Subspecies of Megarhyssa atrata (Fabricius) 
(Hymenoptera: Ichneumonidae) 

By CHARLES C. PORTER 

The subject insect was discovered as a result of a more or 
less preliminary study of the Rhyssini in the collection of the 
American Museum of Natural History. At the outset, there- 
fore, I express my thanks to Miss Alice Gray and Dr. C. H. 
Curran of that institution, the two of whom very kindly made 
it possible for me to pursue these investigations, and to Dr. 
H. K. Townes for his help in verifying my findings. 

The subspecies may be recognized as follows : 

Megarhyssa atrata lineata, new subspecies 

Exactly similar to typical form in structure, size, and general 
habitus. Distinguished by the following color characteristics : 
A line on the upper margin of prothorax, similar line on its 
lower front margin, pair of central vittae on mesonotum, scu- 
tellum except extreme base, the postscutellum, spot below tegulae 
of both anterior and posterior wings, thin lateral line on first 
two sternites and their apices narrowly, yellow. General color 
somewhat more brownish than in typical form, central lobe of 
mesoscutum anteriorly especially so, forming a marked contrast 
with the black lateral lobes. Wings perfectly hyaline, with no 
trace of the deep infumation so characteristic of M. atrata atrata. 
Color otherwise precisely as in typical form. 

The type series consists of two females collected by Mrs. A. T. 
Slosson at Franconia, New Hampshire. Types are deposited in 
collection of American Museum of Natural History. 

In conclusion, it would seem that this represents the extreme 
northern development of M. atrata. In this conclusion Dr. 
Townes fully concurs. Certainly there is nothing like it among 
the many specimens I have examined from more southerly 
localities.

A New Profenusa from the California Plane Tree 
(Hymenoptera, Tenthredinidae) 

By B. D. BURKS, Entomology Research Division, Agricultural 
Research Service, United States Department of Agriculture 

In the fall of 1956 I received from Dr. L. R. Brown, of the 
University of California at Los Angeles, specimens of a small 
sawfly for identification. These had been reared by Mr. Clark 
O. Eads at Santa Barbara and Santa Monica, California, from 
leaf mines on the California plane tree, Plat anus racernosa, dur- 
ing May and June of 1956. The information supplied with the 
specimens was that they had developed from larvae which lived 
in leaf mines superficially resembling those made by the graci- 
lariid moth Lithocolletis jelinella (Heinrich) on the same tree. 
Both the moth and the sawfly make blotch mines. 

Study of these sawfly specimens showed that they repre- 
sented an undescribed species of the genus Profenusa MacGil- 
livray, as defined by Benson (1941, Proc. Roy. Ent. Soc. 
London, ser. B, 10: 85-90). This genus in the Nearctic region 
contains the species alumna (MacGillivray), which mines Betula 
leaves; canadensis (Marlatt), mining Crataegus leaves; inspi- 
rata (MacGillivray), the host of which is unknown; and lucijex 
(Ross), also of unknown host. The host likewise is unknown 
for the closely related Setabara histrionic a (MacGillivray). 

Profenusa platanae, new species 

This species most closely resembles P. inspirata (MacGilliv- 
ray) in being mostly black and in having the ovipositor sheaths 
exserted. The two differ in that the sheaths in inspirata are 
broad and short, while they are slender and long in platanae, 
see Fig. 4. In inspirata (see Ross, 1936, Trans. 111. Acacl. Sci. 
29: 264, Fig. 2) the lancet of the saw has the ventral margins 
between the apical 4 lobes minutely serrulate, while these mar- 
gins are smooth in platanae, Fig. 1 ; the lobes in inspirata have 
extremely minute sub-denticles, but in platanae each lobe bears 
4 relatively large teeth. P. platanae differs from Setahara his- 



208 ENTOMOLOGICAL NEWS | Oct., 1957 

trionica (MacGillivray) in having cell R, of the hind wing open 
rather than closed; the two differ also in that histrionica does 
not have the ovipositor sheaths exserted and has the hind tibia 
almost completely brown. The hind tibia in platanac is almost 
entirely yellow. 

Female: Length, 4.0 mm. Head and body black; antenna 
black, with narrow band at apex of pedicel yellow and apical 
segment of flagellum very dark brown ; tegula mostly yellow, 
a small dorso-basal area black ; wings hyaline with venation 
brown ; apices of all femora, fore and middle tibiae, and all tarsi 
yellow, coxae and basal area of each femur black, second tro- 
chanter of each leg dark brown, hind tibia yellow with apex 
shaded with dark brown. 

Surface of head and body smooth, shining ; fronto-vertex and 
temples of head densely clothed with fine, golden hair ; clypeus, 
labrum, and normally exposed portions of mandibles clothed 
with slightly sparser and longer golden hair ; pronotum laterally 
setose, mesonotum glabrous, dorsal half of mesepisternum finely 
setose, this sclerite ventrally glabrous ; all coxae apically setose, 
trochanters densely setose, femora sparsely setose, tibiae and 
tarsi very densely setose ; dorsum of abdomen glabrous, venter 
very sparsely setose ; exserted ovipositor sheaths each with 6 to 
8 rather long, slightly curved setae and a few short hairs, Fig. 4. 

Head with genae acarinate laterally ; relative proportions of 
parts of antenna : Scape 33, pedicel 25, first flagellar segment 50, 
second 35, third 30, fourth 30, fifth 25, sixth 25, seventh 25; 
pedicel twice as long as wide. Forewing with crossvein 2r 
joining Rs basad of 3r-m, first abscissa of Rs wanting or very 
faintly indicated, 2r-m very short ; vein M with portion between 
Im-cu and 2r-m and just distad of 2r-m, and crossvein 2m-cu 
minutely fractured, similar minutely fractured sectors in 2r and 
3r-m ; vein 2A very weak near its apex, vein 3A straight, but 
obsolescent. Hind wing with 1 1 or 12 hamuli, basal ones widely 
spaced ; cell R, open ; anal cell present, vein 3 A represented by 
a straight stub. Hind tarsus three-quarters as long as hind 
tibia ; tarsal claw with a large basal lobe, Fig. 2. Lancet of 
saw with 4 pointed teeth on lobes, Fig. 1.

Mature larva: Thorax only slightly thicker than abdomen and 
of the same width. Length 9.0 mm., width of head 1.1 mm.. 



210 ENTOMOLOGICAL NEWS | Oct., 1957 

width of metathorax 1.9 mm., width of third abdominal segment 
1.9 mm., width at anterior margin of ninth abdominal segment 
1.25 mm., width at posterior margin of ninth segment 1.1 mm. 
Head and legs very pale brown, mandibles brown, body cream 
colored, dorsal and ventral thoracic shields wanting. Labrum 
bearing 2 bristles near either lateral margin, a pair of sublateral, 
arcuate rows of brown micro-denticles borne on lower, inner 
face of labrum, and a row of smaller, more widely set micro- 
bristles extending across outer ventral margin of labrum. Each 
mandible bearing one bristle at base. Clypeus bearing one 
bristle near either dorso-lateral angle. Antenna with 2 seg- 
ments, basal one large and almost as broad as long, apical one 
minute, papilliform. A row of 6 bristles extending across fronto- 
vertex between the 2 ocellarae. Surface of body obscurely 
shagreened, not spinulose ; spiracles slit-like, not winged ; tho- 
racic legs 4-segmentecl ; prolegs present on abdominal segments 
2 to 8, and very poorly developed, lacking spines or setae ; anal 
larvapod wanting. Abdominal tergites 2 to 8 each with 2 well- 
marked annulets, anterior annulet one-third as long as posterior 
one ; posterior end of body blunt. 

This is the larva that leaves the mine and drops to the ground 
to pupate in an earthen cell. 

Penultimate larval instar : Thorax wider and thicker than 
abdomen. Length of body 7.5 mm., width of head 1.1 mm., 
width of metathorax 1.5 mm., width of third abdominal seg- 
ment 1.4 mm., width at anterior margin of ninth abdominal 
segment 1.25 mm. 

This is presumably the last larval instar that feeds. 

Mine: Begun as a serpentine mine, developing into a blotch 
mine, the blotch mines commonly multiple and coalescent, in 
the leaves of Platanus raccinosa. Excrement in young mines 
concentrated in the center, in mature mines tending to form 
bands near lateral margins.

Redescriptions of Ewing's Oribatid Mites, V 
Families Belbidae and Opiidae (Acarina: 

Oribatei) l 

By TYLER A. WOOLLEY, Department of Zoology, Colorado 
State University, Fort Collins, Colorado 

This paper is the fifth in a series which deals with redescrip- 
tions of Ewing's type oribatid mites. The accompanying fig- 
ures were completed from pencil drawings sent to the writer by 
Dr. E. W. Baker of the U. S. National Museum. Acknowledge- 
ment of these drawings is made by Dr. Baker's initials on the 
finished plates. Ewing's original descriptions are followed as 
closely as possible, but the writer incorporates modern acarologi- 
cal terms where needed. 

Both Grandjean (1936) and Strenske (1955) indicate fea- 
tures which can be employed to differentiate the genera of the 
Belbidae. The solenidions, or tactile hairs, constitute one of 
these morphological features ; other characters also are men- 
tioned by these authors. Many of these diagnostic features 
were not known to Ewing. Most of his descriptions were ac- 
companied by an illustration or two, but in many instances the 
figures represented single diagnostic features such as a pseudo- 
stigmatic organ, lamella, leg, etc. In many cases Ewing did not 
illustrate the entire mite, which is the situation in some of the 
belbids described by him. 

The descriptions in this paper are as detailed as possible 
with the information available from Ewing's figures and de- 
scriptions and the drawings from Dr. Baker. The figures show 
the whole body of the mite and the proximal segments of the 
legs. Solenidions and other critical details are lacking in the 
descriptions and figures because the writer does not have ac- 
cess to the type specimens. It is impossible to be absolutely 
certain of the generic designations of all of these mites, but the 
writer has placed them as accurately as possible. He has used 
Ewing's designations for some of them until such time as the

Foundation.

type specimens can be examined critically for solenidions and 
other details. Despite the latter difficulties, these redescriptions 
should be of value because the fragmentary accounts and il- 
lustrations of these mites have been embellished in this paper. 

FAMILY BELBIDAE WILLMANN, 1931 

These apterogasterine mites are distinguished by legs which 
are longer than the body and frequently consist of bead-like seg- 
ments. Legs III and IV are usually inserted in the lateral 
margins of the body and the dorsal surface of the hysterosoma 
is not reflected ventrally. In some instances the cast nymphal 
skins are carried on the dorsum of the hysterosoma. 

Genus HETERODAMAEUS, n. g. (Figs. 1, 2) 

Description: Sclerotized sculpturing on dorsum of propo- 
dosoma between and anterior to the pseudostigmata ; a transverse 
suture on dorsum of propodosoma at level of insertions of rostral 
hairs ; pseudostigmatic organs large, clavate, setose ; dorsum of 
hysterosoma with four posterior setae in a transverse row ad- 
jacent to posterior margin of hysterosoma; surfaces of propodo- 
soma, hysterosoma and legs with many small tubercules ; a large 
spine projecting laterad from the rim of camerostome to the 
edge of tectopedia I anterior to level of coxae I. 

Heterodamaeus magnisetosus (Ewing), 1909. (Figs. 1, 2) 
Cotype : Damacus magnisetosus Ewing, 1909, p. 129. 

Description: Chestnut brown; propodosoma about two-thirds 
as long as hysterosoma and about three-fourths as wide, some- 
what triangular in shape, surface pebbled with many small 
tubercles. A transverse, sclerotized ridge and suture between 
insertions of rostral hairs. Rostrum blunt, depressed ; rostral 
hairs inserted in lateral margins of sclerotized transverse ridge 
which runs between them, about as long as transverse ridge, 
stout and pectinate, curved medially until they nearly meet an- 
terior to tip of rostrum. Lateral margins of propodosoma ex- 
panded in prominent tectopedia of legs I and II ; tectopedia I 



Ixviii] ENTOMOLOGICAL NEWS 213 

larger and directed anteriorly. Lamellae absent. Lamellar 
hairs fine, simple, inserted about half their lengths anterior to 
pseudostigmata and directly laterad of antestigmatic bar. In- 
terlamellar hairs not visible, but insertions of these hairs are 
mediad and anterior of pseudostigmata. Three sclerotized bars 
or ridges on dorsum of propodosoma anterior to pseudostigmata 
(fig. 1 ) . Anterior bar curved posteriorly at lateral ends, curved 
apex at level of tectopedia I in mid-dorsal area of propodosoma. 
A posterior bar behind and forming an eye-like loop (fig. 1). 
Two antestigmatic bars which extend between insertions of 
lamellar and interlamellar hairs and end at antero-lateral mar- 
gins of pseudostigmata (fig. 1). Pseudostigmata large pits 
with sclerotized rims at posterior end of antestigmatic bar, 
mediad of level of tectopedia II, cup projected above surface of 
propodosoma. Pseudostigmatic organs about as long as leg 
II, clavate, the head nearly as wide as opening of pseudostig- 
matic cup and about one-third as long as entire organ, setose 
(Ewing says: "pectinate"), with a long, thin pedicel, slightly 
curved, but extended laterally. 

Hysterosoma globose, surface pebbled like propodosoma, evi- 
dently covered with an exudate, lateral margins bent ventrally 
slightly ; four pairs of visible setae in a transverse row near 
medio-posterior margin; a pair of glandular fissures (?) in 
mid-lateral surfaces of dorsum (fig. 1). 

Ventral margins of propodosoma with a prominent lateral 
spine anterior to leg I, extending from lateral rim of camero- 
stome to margin of tectopedia I. Ventral plate circular in out- 
line, about as broad as long, broken on right side in cotype speci- 
men. A single pair of setal insertions visible anterior to genital 
opening (fig. 2). Genital aperture subrectangular, at level of 
leg IV. Genital covers as wide as anal covers, but half as long; 
genital setae not visible. Anal aperture nearly twice as long 
as genital opening, separated from genital aperture by half the 
width of a genital cover. Anal covers slightly opened in cotype 
specimen ; no visible anal setae. 

All legs with pebbled, tuberculate surface. Ewing (1909) 
states : "First pair of legs as long as the body ; second pair about 



214 ENTOMOLOGICAL NEWS [Oct., 1957 

three fourths as long as the first pair ; third pair equal to the 
first, and the last pair of legs the longest of all. Tarsus of leg I 
shorter than the tihia. The tibia of leg I is peculiar in this spe- 
cies in that it possesses a large process or tubercle at its dorsal 
distal aspect from which arises a large, long, tactile hair. Un- 
gues tridactyle, situated on very long and slender tarsal pedicels ; 
dactyles unequal." 

Length 560 /A, hysterosoma 360 /x; width 330/t. 

Specimens of this species were collected in moss by C. A. Hart 
at Pulaski, Illinois and by H. E. Ewing at Arcola, Illinois. 

Discussion: Ewing (1909) considers this species remarkable 
because of the large pseudostigmatic organs, the tibial projection 
on leg I, and the shorter length of the second pair of legs. The 
writer contends that the sclerotized ridges on the propodosoma, 
the large pseudostigmatic organs, the ventral spines lateral to 
the camerostome and the four dorsal posterior setae are valid 
evidences for the generic designation of this species. 

Damaeus michaeli Ewing, 1909, p. 129. (Figs. 3, 4) 

Description: Chestnut brown; propodosoma broadly triangu- 
lar in outline, insertions of legs I and II making posterior two- 
thirds broader than anterior end. Rostrum with a sclerotized 
margin, somewhat square in outline ; rostral hairs curved, stout, 
inserted in antero-lateral corners of sclerotized margin. Lamel- 
lae absent, lamellar hairs inserted twice the width of insertions 
posterior to rostral hairs ; lamellar hairs stout, curved, nearly 
as long as width of rostrum. Interlamellar hairs inserted be- 
tween pseudostigmatic organs, directed anteriorly. Pseudo- 
stigmata funnel-shaped, placed mediad of space between legs I 
and II in lateral margin of propodosoma, with a sclerotized rim. 
Pseudostigmatic organs flagelliform and barbed (Ewing says: 
"pectinate"), directed laterad and upward. Tectopedia III 
with stout spines projecting somewhat anteriorly near margin 
of propodosoma. Spinae adnatae stout, slightly decurved at 
tips, arising at level of leg III, projected anteriorly from beneath 
anterior edge of hysterosoma (fig. 3). 



Ixviii] ENTOMOLOGICAL NEWS 215 

Hysterosoma globular, about twice as long as propodosoma, 
lateral edges curved ventrally, surface brittle, almost smooth, 
with eight pairs of curved, stout, pectinate bristles in two medio- 
lateral rows on dorsum (fig. 3). 

Camerostome pyramidal with two fine, short bristles near 
chelicerae. Venter of propodosoma with sclerotized margins, 
four pairs of bristles lateral and posterior to camerostome (fig. 
4), posterior margin of propodosoma with two short, blunt 
spines which project posteriorly and evidently fit into small 
recesses in venter of hysterosoma. Genital opening subglobose 
in outline, about as long as anal aperture, but slightly wider ; 
genital covers rectangular, each cover with six genital setae in 
a row closer to medial edge than to lateral ; g : 1 close to anterior 
margin of cover; g : 2-g : 6 equally spaced posteriorly. Two 
pairs of adgenital setae as in fig. 4. Anal opening slightly nar- 
rower than genital aperture, oval in outline, covers narrower 
than genital covers ; each cover with two pairs of anal setae ; a: 1 
closer to anterior margin of anal cover than a : 2 is to the pos- 
terior margin (fig. 4). Two pairs of adanal setae near pos- 
tero-lateral curve of anal aperture. Two pairs of fine, simple 
setae on decurved surface of dorsal plate, each pair postero- 
laterad of adanal setae, but with more widely separated inser- 
tions. 

Ewing (1909) states: "Legs stout; femora with narrow 
peduncle and large clavate head ; each segment bears several 
stout, curved, pectinate bristles. Portions of cast skin generally 
carried on the dorsum of the abdomen." 

Length 495 /x, hysterosoma 380 p. ; width 320 /x. 

Many specimens of this species were collected by H. E. 
Ewing in moss and under bark of logs at Homer, Illinois. 

Damaeus globifer Ewing, 1913, p. 120. (Figs. 5, 6) 

Description: Chestnut brown. Propodosoma about two- 
thirds as long as hysterosoma, broadly triangular. Rostrum 
blunt, cone-like ; rostral hairs inserted about a third their 
lengths posterior to rostral tip on lateral edges, incurved so that

216 ENTOMOLOGICAL NEWS [Oct., 1957 

about a third their lengths posterior and medial to rostral hairs ; 
a sclerotized, raised lateral prominence between rostral and 
lamellar hairs (fig. 5). Sclerotization of insertions of legs I 
prominent, visible at lateral margins of propodosoma. Inter- 
lamellar hairs inserted medial to pseudostigmata, long, filiform, 
broken at tips in type specimen. Pseudostigmata prominent, 
funnel-shaped, between expanded insertions of legs I and II and 
on slightly raised prominence lateral to insertions of interlamellar 
hairs. Pseudostigmatic organ long, stout, slightly pectinate. 
Spinae adnatae stout, curved laterad at tips, inserted about twice 
their lengths posterior to pseudostigmata. (Ewing (1913) 
states that these spine-like spurs curve inward, but his illustra- 
tion in the same article shows them curved outward in the fash- 
ion indicated in fig. 5.) 

Hysterosoma spherical, smooth, with nine pairs of stout, 
curved, simple setae on dorso-lateral aspects, their raised in- 
sertions arranged in an elongated oval on the dorsum ; tips of 
some bristles broken in type specimen. 

Camerostome trapezoidal, a pair of setae posterior to chelic- 
erae and medial to tectopedia I. Apodemata II narrow, de- 
curved bars, medial portion indistinctly projected medio-pos- 
teriorly beneath integument. Three simple setae inserted in a 
diagonal line on each side from level of tectopedia II to level of 
lateral spine between legs II and III (fig. 6). A large curved, 
lateral spine at junction of propodosoma and hysterosoma be- 
tween legs II and III; a small lateral spine projects anteriorly 
close to base of the large lateral spine. A long lateral spine be- 
tween legs III and IV. A simple decurved bristle anterior to 
coxa IV ; other ventral setae as shown in fig. 6. Genital open- 
ing rectangular, directly between legs IV, each corner rounded,

from genital aperture, oval in outline ; anal covers opened 
slightly, each with two simple bristles in medial aspects of 
cover. Adanal setae as seen in fig. 6. 

Ewing's descriptions of the legs is as follows : "All segments 
of the legs with a swollen portion ; second pair of legs subequal 
to the others. Femora of legs with a thin proximal part ; distally 
suddenly enlarged. Anterior pair of legs about as long as the 
whole body. Distal end of tibia of leg I without a large tubercle 
bearing a tactile hair. Femur of leg IV with a very long, tac- 
tile bristle at its distal end." 

Length 711|u,, hysterosoma 500 /^; width 500 /t. 

The type specimen was collected by J. E. Guthrie on decaying 
mushrooms at Jordan, Minnesota. 

Discussion: Ewing indicates that this species is similar to 
D. sufflexus Mich., but the hairs on the dorsum of the hystero- 
soma are "about twice as long as those of sufflexus" With the 
current use of solendidions and minute details for differentiation 
of genera and species, better comparisons cannot be made with- 
out study of the type specimens of these belbid mites. 

FAMILY OPIIDAE GRANDJEAN, 1953 

The opiid mites constitute the smallest of the Oribatei. Their 
coloration is usually light yellowish brown, their legs are like 
those of most eremaeids, but their body size seems to separate 
them rather easily from the latter and from other Oribatei. 
Ewing (1917) used Damaeus as the generic designation of one 
of his mites, which would place it in the family Belbidae. Its 
propodosomal configurations and its size, however, indicate that 
it belongs in the Family Opiidae as designated by Grand jean 
(1953). 

Oppia minuta (Ewing), 1917. (Figs. 7, 8)

cover from anterior end ; a : 2 inserted in medio-posterior corner 
of each cover. 

Ewing (1917) states that the "legs (are) prominent, but 
short for the genus ; anterior pair extending beyond the tip of 
the rostrum by over one-half their length, tarsi longer than tibiae, 
tibiae each with a long tactile hair at its tip above, which extends 
beyond the tip of the tarsi. Coxae of third pair of legs sub- 
spherical in shape, each with a small tubercle on its anterior as- 
pect and a single strongly curved, singly pectinate bristle. 
Posterior legs extending beyond the tip of the (hysterosoma) 
by the full length of their tarsi. Most of the segments of the 
legs are moderately swollen toward one end, and pedicellate at 
the other end." 

Length 293 //,, hysterosoma 207 p ; width 153 p.. 

This species was collected in Illinois, but the locality and the 
collector are unknown. Dr. Ewing had a single specimen "of 
this very minute and rare species." 

Discussion: It seems obvious from the comparisons of this 
species with drawings and descriptions of genera in Belbidae 
that the species described above does not belong in any of the 
belbid genera. Its size and other features of the body conform 
to the characters of the genus Oppia, for which Grand jean 
(1953) designated the family Opiidae. The configurations on 
the propodosoma are unlike those of any others the writer has 
seen in the literature and he therefore considers this to be a valid 
species in the genus Oppia.

The Status of the Tortoise Beetle Metriona 
ormondensis Blatchley 

By MILTON W. SANDERSON, Illinois Natural History 

Survey, Urbana 

In 1920 Blatchley (Can. Ent. 52: 71) described Metriona 
ormondensis on the basis of two specimens taken on wild morn- 
ing-glory (possibly Ipomoea) at Ormond, Florida, April 13, 
1913. He mentioned that Barber (1916, Proc. Ent. Soc. 
Wash. 18: 125) had called attention to a larger, more de- 
pressed and more highly colored Florida specimen in the 
Schaeffer collection which Barber regarded as a local race of 
Metriona purpurata Boh. but which Blatchley thought repre- 
sented his new species. Schaeffer (1925, Jour. N. Y. Ent. 
Soc. 33 : 233 ) stated that ormondensis possibly was only a 
variety of purpurata. Thus the question of the status of ormon- 
u . nsis has remained for more than 30 years. 

Through the courtesy of the Department of Entomology at 
Purdue University, I have been permitted to examine the two 
Blatchley specimens of ormondensis, and I am therefore able 
to offer some information to support its specific status. Sander- 
son and King (1951, Jour. Kans. Ent. Soc. 24(4) : 125-128) 
noted the value of the structure of the tarsal claws for sex and 
species recognition in some species of Metriona. Blatchley did 
not mention the claws of ormondensis nor did he indicate the 
sex of his specimens but examination of the types has disclosed 
that the type female and the paratype male differ with respect 
to claws, and that these differ from both sexes of pnrpnrata. 
The anterior claws of both sexes of ormondensis each has an 
inner marginal basal angulation or tooth (hereafter referred to 
as tooth) ; one posterior claw is toothed, the other untoothed : 
both middle claws of the male of ormondensis are untoothed ; 
and in the female one claw only is toothed. The female of pur- 
purata has all claws toothed except for one untoothed middle 
claw. These differences for both sexes of the two species are 
expressed in the following key : 



Ixviii] ENTOMOLOGICAL NEWS 223 

Metriona onnondcnsis and purpurata 

1. Each tarsal claw with a broad basal angulation or tooth on 

inner margin ; female purpurata Boh. 

At least one claw of middle tarsus untoothed 2 

2. Both middle tarsal claws untoothed ; male 

onnondcnsis Blatch. 

Only one middle claw untoothed 3 

3. Only one posterior claw untoothed ; female 

ormondensis Blatch. 

Both posterior claws toothed; male purpurata Boh. 

In addition to the foregoing differences, the dorsum of ormon- 
densis is duller, and the beetle averages a little larger than 
purpurata.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Martnaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

Biological Observations on Ectemnius with Partic- 
ular Reference to their Ogcodes prey (Hymen- 
optera: Sphecidae. Diptera: Acroceridae) 

By ROBERT C. BECHTEL a and EVERT I. SCHLINGER 2 

It is known that various species of crabronid wasps provision 
their nests with adult flies. Accurate reports of these associa- 
tions are not numerous, however, and there are apparently no 
published records of specifically identified American crabronid 
wasps associated with the dipterous family Acroceridae. For 
this reason preliminary observations are presented which indi- 
cate that there may be a frequent predator-prey relationship be- 
tween certain species of the crabronid genus Ectemnius Dahl- 
bom and the acrocerid genus Ogcodes Latreille. Future ob- 
servations and research should uncover additional facts needed to 
understand fully these relationships. 

The first apparent record of crabronid wasps storing acrocerid 
flies as food for their larvae \vas by Westwood (1840) who 
stated that van Heyden and Audouin had observed that numer- 
ous specimens of Ogcodes gibbosus (Linnaeus) were selected 
as food for the progeny of a species of Crabro. Other authors 
reporting similar relationships were: Tournier (1878), Sahl- 
berg (1883), Gorham (1902), Enslin (1922), Marechal (1934), 
Leclercq (1941, 1954), Bristowe (1948) and Sabrosky (1948). 
Our knowledge of these relationships through 1954 was sum- 
marized by Leclercq (1954: 318-319). We infer from this 
that only crabronid wasps of the genus Ectemnius, subgenus 

1 University of California, Davis. 
- University of California, Riverside. 

(225) 



226 ENTOMOLOGICAL NEWS [Nov., 1957 

Hypocrabro Ashmead, are known to have this relationship with 
the Acroceridae. Furthermore, all of the above records (ex- 
cept Sabrosky (1948) which refers to a Nearctic species) per- 
tain to a restricted association with the widespread Palearctic 
crabronid, Ectemnius (Hypocrabro) rubicola (Dufour and Per- 
ris), even though other species of this subgenus are found in the 
same region. 

Another important fact is that all of the recorded acrocerid 
prey belong to the genus Ogcodes. These are 0. gibbosus (Lin- 
naeus), marginatus (Meigen) ( pallipes Latr.), pallipes La- 
treille and sonatns Erichson. As normal Ogcodes specimens 
appear to be of a suitable size for use by these wasps, it is likely 
that certain of the Holarctic genera Acrocera Meigen, Opsebius 
Costa and Pterodontia Gray would be satisfactory also. In ad- 
dition to size, abundance of the prey may be paramount in the 
selection of Ogcodes, rather than any preferential selection of 
flies. This is substantiated by the fact that species of fourteen 
families of Diptera have been recorded as hosts for Hypocrabro. 
On the other hand, we do not have adequate observations on the 
biologies of the various crabronids and perhaps future work will 
demonstrate that other genera and/or species provision their 
nests with acrocerids. 

To our knowledge only two published articles have reported 
the use of acrocerid flies as hosts for Nearctic wasps, and only 
one specified association with a crabronid. James (1938) re- 
corded that a wasp (species unknown), collected at Boulder, 
Colorado, February 28, 1933, by C. H. Hicks, stocked its nest 
with specimens of Ogcodes albicinctus Cole. Some of these 
specimens have been examined and are males of 0. cugonatus 
Loew. The second report was made by Sabrosky (1948) who 
recorded that ten male specimens of 0. pallidipennis Loew 
(western subspecies) had been collected from a crabronid nest 
at Oak Creek Canyon, Arizona, June 8, 1940. The collector, 
G. E. Bohart, noted that "this species of wasp was not seen to 
use any other species of fly." An examination of these speci- 
mens showed them to be a new species of Ogcodes (species No. 
1, Schlinger MS.). 



IxviiiJ ENTOMOLOGICAL NEWS 227 

Two other observations record Ogcodes species from wasp 
nests, but as far as we have been able to determine the wasps 
were probably spider-killing forms. Champlain and Knull 
(1923) recorded adults of "Oncodes dispar (Macquart)" in a 
wasp nest from a decaying log at Wildwood Park, Harrisburg, 
Pennsylvania, in August. They stated that "The wasp ap- 
parently caught the spiders that were infested by the larvae of 
Oncodes, stored them in cells with her eggs, sealed the gallery 
and departed. The Oncodes larvae consumed the spiders and 
possibly the wasp larvae, then transformed and were unable to 
get out. Remains of the spiders were present in the cells." 
Cole (1919) reported that a specimen of 0. palidipennis Loew 
had been bred from a nest of Sceliphron ccmcntarius collected 
at Coulterville, Illinois. 

As previously mentioned, no positive information other than 
the verified record of Sabrosky (1948) has been published on 
the association of crabronids and acrocerids in the Nearctic re- 
gion. It was of interest, therefore, when several nests of 
Ectemnius (Hypocrabro) spiniferus (Fox) were found to con- 
tain specimens of Ogcodes eugonatus Loew. E. spiniferus is 
confined to the western part of the Nearctic region and is com- 
mon in California. For a more detailed distribution see Krom- 
bein (1951: 1027) and Leclercq (1954: map 30). 

In attempting to ascertain the association of crabronids with 
this dipterous family, the excellent "Monographic . . . Cra- 
broniens" of Leclercq (1954) was consulted. This work gave 
only a single Palearctic species, E. (//.) rubicola, as utilizing 
acrocerid flies. On the basis of various characters, we assumed 
that E. spiniferus could be closely related to E. rubicola. This 
assumption was verified by J. Leclercq (in litt., 1956) who 
stated that "From a morphological point of view it is certain 
that Ectemnius (Hypocrabro} spiniferus and E. (//.) rubicola 
are closely allied. I should say however that the closest relative 
of spiniferus in the Palearctic region is by all means lamigatus 
(DE STEFANI)." 

He also stated that there was little information on the habits 
of laevigatus, and it probably provisioned its nests with aero- 



228 ENTOMOLOGICAL NEWS [Nov., 1957 

cerids. Leclercq (in litt., 1956) also mentioned that if species 
groups were erected in Hypocrabro, one such group would in- 
clude laevigatus, rubicola, and spiniferus. 

The prey species, 0. eugonatus (0. olbicinctus Cole, of 
authors), is not common in California north of the Tehachapi 
Mountains. We have examined specimens only from Turlock 
(Stanislaus County) and Davis, Elkhorn Ferry, and Putah 
Canyon (Yolo County) in northern California. This species 
is distributed throughout North America where it ranges from 
Canada to southern Mexico, but it appears to be most common 
in the great plains and eastern United States. Furthermore, 
eugonatus may be conspecific with the European 0. zonatus 
Erichson. If this conspecificity should prove to be correct, it 
would be of particular interest in that the close relationship of 
rubicola and spiniferus would be further substantiated biologi- 
cally. 

The material upon which the following new biological data 
presented in this paper are based was collected at Elkhorn 
Ferry. Yolo County, California, February 12, 1956, by R. C. 
Bechtel. 

The linear nests of spiniferus were located in dead or injured 
and dying twigs of blue elderberry, Sambucus coerulea Rafines- 
que. The cells and their respective partitions of macerated el- 
derberry pith were found at the inner end of the tunnels. These 
tunnels varied in length from 19-36 mm. Details of the cell 
contents are summarized in table 1. 

The length of the cells varied greatly, ranging from 8-22 
mm., whereas the diameter of the cells varied only from 5-7 mm. 
The partitions exhibited a variation in length (4-7 mm.) similar 
to that of the cells, but these lengths appeared to have no cor- 
relation with the associated cells. 

An examination of the cell contents indicated that they could 
be divided into six groups as follows : Crabronids only ; cra- 
bronid cocoons only; fly prey of crabronids (Hylemya, Ogcodcs 
and Sphaerophoria} ; crabronid cocoons, fly prey of crabronids 
and scavenger flies (Megaselia) ; parasite (Monodontomcrus] 
or predator (Cymatodera) of crabronids and fly prey; and fly 
prey and scavenger flies. 



Ixviii] 



ENTOMOLOGICAL NEWS 



229 



Certain cells, other than those which harbored a parasite or 
predator, or from which no spinifents adults emerged, con- 
tained cocoons in which dead crahronid larvae were found. 
The Megaselia apparently did not cause the death of the larvae 
since these flies did not occur in all of the cells. Also, there was 
no evidence of cocoon penetration when they did occur. There- 
fore, the cause of death was unknown. 

Approximately one-half of the specimens of 0. eugonatus 
were in good condition. The other half were partly or almost 
entirely eaten. Some of them lacked the head or legs, while

abdomen and/or thorax and wings present. As a result, we 
were not able to determine the sex of several specimens. 

Individuals of the other fly prey, an anthomyiid (Hylemya, 
det. C. W. Sabrosky) and a syrphid (Sphacrophoria, det. W. W. 
Wirth), were in such poor condition that specific identification 
was impossible. The numerous wings and body fragments in 
the cells indicated that additional specimens of these genera had 
been present, however. 

A single specimen of a new species of the torymid genus 
Monodontomerus (det. P. H. Timberlake) was reared from 
one Ectemnius cocoon. Peck (1951:528-529) listed various 
Hymenoptera as hosts for Monodontomerus, but no Crabronini 
were included. Therefore, this appears to be a new host record 
for the genus. 

A clerid predator, a larva of Cyinatodcra ovipcnnis LeConte, 
was found in one twig. This larva had chewed a hole in a 
spiniferus cocoon, eaten approximately % of the crabronid 
larva, and was later observed to consume the remainder of it. 
There were indications also of two additional cells which the 
predator presumably had destroyed. 

Several of the cells contained larvae and pupae of a phorid, 
Megaselia sp. (det. W. W. Wirth). Various authors have re- 
ported a parasitic relationship of Megaselia species with insects 
(Clausen, 1940: 385-386), but this species appeared to be a 
scavenger. It is of interest that in the cells in which the cra- 
bronid larvae failed to develop, the adult Ogcodcs specimens 
were not used as food by the phorids, while the other host speci- 
mens were almost entirely consumed. Also, some of the cells 
in which this scavenger occurred had a blackened appearance 
due to the presence of a fungus. 

In addition to the above observations, two other instances of 
a crabronid-acrocerid relationship have been noted. Four male 
specimens of 0. citc/onatiis, collected at La Mesa, San Diego 
County, California, January 22, 1953, by F. X. Williams, were 
examined. A label on these specimens included the data "in 
Crabro wasp nest." Williams (in litt., 1956) stated that his 
notes read "La Mesa . . . also a nest of Crabro sp. with many 



Ixviii] ENTOMOLOGICAL NEWS 231 

dead (last year's) acrocerid flies only, of one species in cells, 
and Crabro cocoons ; . . . likewise in dead Salvia stems (Salvia 
apiana Jepson)." He stated also that he used the name Crabro 
in a general way, that the wasp could have been Ectemnius and 
that only the better acrocerids were retained. 

Also, we have studied four male and three female specimens 
from Escragnoles Alpes, France, labeled "ex. Crabro nest." 
This record was of interest since it was the first time that female 
Ogcodes specimens have been found in a crabronid nest. Fe- 
male Ogcodes seldom fly, but males make short, rapid flights 
at frequent intervals and are more subject to capture by female 
crabronids. 

Another unverified association was found during the exami- 
nation of twelve male specimens of a new species of Ogcodes 
(species No. 2, Schlinger MS.). The specimens were collected 
in San Bernardino County, California, elevation 6,000 ft., August 
2, 1940, by J. A. Comstock. Labels on the specimens referred 
to a museum note which read, "12 Hymenopterous cocoons in 
the pith of Sambncus relutina. In one cell were the stored re- 
mains of 15 little flies (Cyrtidae), of which, though mouldy, a 
chloroform treatment made 12 available for mounting. All of 
these wasps had stored the same fly, but in case the larval wasp 
had matured, the flies were all consumed."

A New Ambrysus from Mexico (Hemiptera, 

Naucoridae) 

By IRA LA RIVERS, University of Nevada, Reno 

Subfamily AMBRYSINAE Usinger, 1941 
Genus Ambrysus Stal, 1862 

Ambrysus drakei, sp. nov. 

General appearance: A rather large, robust species with the 
mottled coloration typical of Ambry si. Size 12.0-13.0 mm. long 
and 7.5-9.0 mm. wide. Dorsum lighter over prothorax and 
head, where the background color is light yellowish, darker 
brownish over hemelytra ; embolia the only prominently light 
area in the otherwise dark hemelytra ; scutellum with a faint 
reddish caste. Venter light yellow, slightly darker on abdo- 
men, legs whitish-yellow. 

Head: Sparsely punctate, shiny, comparatively flat; vertex 
only very faintly protuberant before eyes, forming an almost 
smooth, nearly flat contour between leading angles of the eye. 
Eyes essentially flush with general head surface ; outer and pos- 
terior eye margins not forming a smooth, uninterrupted semi- 
circle, but showing a slight angulation at their meeting points, 
which is the anterior inception of the thin but prominent border 
of the posterior eye margin. Labrum smoothly rounded, but its 
outline, rather than being an even semicircle, suggests a point- 
ing of the tip; ratio of length-to-width 23: :40 (58%), uniform 
in color ; mouthparts similar to head in color, darkening toward 
tip. Head ratios are : 



Ixviii] ENTOMOLOGICAL NEWS 233 

(1) total length to width (including eyes) 43: :68 (63%) 

(2) anterior distance between eyes to posterior distance 32: : 
40 (80%) 

(3) anterior distance between eyes to inner eye length 31 : :28 
(90%) 

(4) posterior distance between eyes to greatest length of head 
posterior to this line 40: : 10 (25%) 

Pronotutn: Moderately punctate, shiny; background color 
light yellowish, bearing five prominent brownish areas within 
the disc, composed of aggregations of brown spots in the manner 
typical of Ambry si in general; posterior border rather broad, 
separated from disc by thin black line; lateral edges smooth, 
non-pilose, weakly curved, curvature more pronounced at hind 
angle (postero-lateral angle) per cent of curvature (viewed 
perpendicular to the frontal plane of section of the animal as 
a unit) about 12% (av. 68: :8) ; venter light yellowish, promi- 
nently pilose along posterior edge, particularly centrally, about 
the keel and the procoxal cavities ; keel ridged anteriorly, flatly 
sloping posteriorly beneath median union of propleura, the 
slope smooth except for suggestion of transverse rugulosity 
ratio of anterior keel ridge to total keel length (including poste- 
rior sloping face) 45:: 70 (64%). Prosternum free from pro- 
pleura, and disappearing caudad beneath the latter. Propleura 
united along median line just posterior to prosternum. Pro- 
notal ratios are : 

( 1 ) width between anterior angles to width between posterior 
angles 68:: 135 (50%) 

(2) median length to greatest width 44: : 135 (33%) 

(3) distance between anterior and posterior angles on same 
side to perpendicular distance between anterior angle and 
baseline of pronotum 65 : : 62 

Scutellum: A pale reddish brown with light yellow area at 
posterior angle and some lightening in color laterally ; ratio of 
three sides, anterior and two laterals, 90: :68: :68. 



234 ENTOMOLOGICAL NEWS [Nov., 1957 

Hemelytra: Background color nearly unicolorous brown-black, 
with some light yellowing, most prominently on embolia ; rather 
shiny, punctate, each puncture with a whitish spot ; embolium 
well defined at its posterior edge, rather broad for the genus 
(length-to- width 75: '.28 = 37%) emboliar crease very weak, 
barely noticeable in anterior one-fifth embolium typically bi- 
colored, light yellow in anterior two-thirds, reddish brown pos- 
teriorly with rather pronounced contrast between the two areas. 
Hemelytra rather markedly exposing lateral connexival spinose 
margins posterior to embolia, and attaining abdominal tip. 
Wings functional, as long as hemelytra, and possessing the usual 
large, "costal" cell. 

Venter: The prothoracic venter has been discussed above. All 
connexival segments moderately spinose except Segment I, the 
angles being acutely prolonged posteriorly ; Segment I angle is 
right-angulate, not protruding laterad of general body outline, 
and is non-spinose. Connexival Angles II-IV are the most 
prominent, becoming progressively larger anterior-to-posterior ; 
lateral connexival edges essentially smooth, non-serrate, even 
with considerable magnification. Tip of female subgenital plate 
quadrisinuate in terminal outline, the two inner sinuosities 
grouped together as two low, rounded angles, the two outer 
sinuosities sharp-angulate and not reaching as far caudad as 
the median portion. Actually, this tip outline is a combination 
of the characteristics of A. mexicanus (A. dilatus, A. hintoni) 
and A. fuscus; the sinuation is indistinguishable from that of 
A. fuse-its, and the left lateral asymmetry of A. mc.vicanns may 
be quite evident (see illustration). The male genital process is 
prominently developed, and greatly resembles that of a small 
A. guttatipennis or a large A. mexicanus (see illustration). 

Legs: Prolegs coxa and trochanter usual for the genus. 
Femoral incrassation about average, ratio of length to greatest 
median width 60:: 36 (60%); tibia average, combined tibia- 
tarsus, when closed, just attaining adjacent (proximal) end of 
femur. 

Mesolegs coxa and trochanter usual ; femoral ratio of length 
to greatest median width 60: : 11 (18%) length 2.6 mm. ; tibia 



ENTOMOLOGICAL NEWS 235 

with usual spination for the subgenus Ambrysiis distal end 
ventrally with two prominent transverse rows of spines set 
across tibial width, the terminal row set solidly across apex, 
the secondary or proximal row extending only about half way 
across tibial width ratio of length to median width 55::8 
(15%) length 2.5 mm.; tarsus long, narrow, whitish, 3-seg- 
mented, the first segment very small and usually hidden by 
terminal spines, third segment terminating in two prominent, 
moderately curved claws.

236 ENTOMOLOGICAL NEWS [Nov., 1957 

Comparative data: Ambrysus drakei is a member of the sig- 
norcti group of the genus, and while it is an easily separable 
species, presents the rather interesting appearance of being in- 
termediate between two of the rather subtle and un-named, but 
broadly recognizable, sections of the genus. The signorcti group 
per se is one in which broadness of form, including emboliar 
inflation, prominent maculation and quite often pronounced con- 
nexival spination, is the rule ; whereas the closely related section 
typified by A. mc.vicanus, is somewhat slimmer, more uniformly 
colored and relatively or entirely spineless along the connexival 
margins. In general ovality, noticeable color contrast and lateral 
connexival spination, A. drakei is undeniably a typical part and 
parcel of the signoreti group ; in its pronounced A. me.vicanus 
type of female subgenital plate outline, it is rather aberrant and 
closely linked to this latter group. Fortunately, at least with 
present material, the species is not as confusing as the above 
comparison may sound, and it readily segregates from its rela- 
tives by the insertion of the following auxiliary couplet in the 
published key to Mexican Ambrysi 

27 (26). Lateral apical angles of female subgenital plate promi- 
nent, sharp, even with median, low-rounded angles or 
sinuosities ; median angles set close together, their width 
across tips 40% or less of total width between lateral apical 
angles ; male genital process either narrowing conspicuously 
and pointedly toward tip, or weakly goosehead-shaped . . 27A 
Lateral apical angles of female subgenital plate weak, al- 
though even with median, low-rounded angles or sinuosi- 
ties, which latter are hardly more than flattened curves 
along mid-line of tip ; median angles wide, their width across 
tips more than 50% of total width between lateral apical 
angles ; male genital process not distinctive, weakly-to- 

moderately curved and not shaped as above 

signorcti-portheo 

27 'A (27). Connexival angles non-spinose; smaller species, 
8.5-9.5 mm. long; lateral apical angles of subgenital plate 
long, comparatively narrow, sharp and spinosely produced, 
the concavity between them and the median angles deep; 
male genital process progressively narrowing to tip, inner 
terminal corner enormously produced into a straight-edged 



Ixviii | ENTOMOLOGICAL NEWS 237 

long process, somewhat like a greatly exaggerated, thin 

foot juscus 

- Connexival angles spinose; larger species, 12-13 mm. 
long; lateral apical angles of subgenital plate shorter, 
broader, although with rather sharp tips, the concavity be- 
tween them and the median angles rather shallow; male 
genital process not as above, but much like guttatipennis, 
i.e., somewhat goosehead-shaped drakei 

For those specimens of A. drakei which show a slight asym- 
metry of the left side of the female subgenital plate such as oc- 
curs conspicuously in A. mexicanus, the spinosity of the con- 
nexival angles, size and increased inflation of the embolia (width 
more than 35% of length) will readily separate them from A. 
mexicanus (= emboliar width less than 35% of length).

Trichobius (Streblidae) in West Virginia (Dipt.) 

By J. O. WHITAKER, JR., 34 East Street, Oneonta, N. Y. 

On March 23 and 24, 1957, I found Streblid flies of the genus 
Trichobius on the long-eared bat (Corynorhinus rafinesquii 
rafinesquii) in Pendleton County, West Virginia. There is 
some disagreement as to the taxonomic standing of this para- 
site. It is considered as Trichobius major, variety quadriseto- 
sus, by Kessel (1925), as Trichobius quadrisetosus by Curran 
(1935), and as Trichobius corynorhini by Jobling (1938), who 
considers this and Kessel's variety, quadrisetosus, as synonyms. 
In the key by Kessel, the only difference between corynorhini 
and major is the dark line marking the transverse suture in 
major. I am inclined to agree with Jobling, and would desig- 
nate the West Virginia specimens as T. corynorhini, possibly 
as subspecies quadrisetosus. 

In the two caves of West Virginia in which I made my collec- 
tions, Sinnit and Minor Rexrode, I found this fly to be very 



238 ENTOMOLOGICAL NEWS [Nov., 1957 

common. There were from zero to six flies crawling on each 
Corynorhinus, with an average of about three per bat. This 
population was marked by very little variation in the taxonomi- 
cally important characters, with the exception of the number of 
eye facets. Thirty-seven specimens were examined, and the 
following results were obtained. 

a. The transverse suture of the mesonotum was marked by 
the dark line in every case. 

b. In 33 cases the median line of the mesonotum extended to 
the transverse suture. In three it extended .8 of that distance, 
and in one it extended .9 of that distance. 

c. The number of scutellar bristles was four in every case. 

d. The number of eye facets varied from 12 to 16, with an 
average of 13.08, and a standard deviation of 1.10. 

e. Pubescence was comparatively sparse in all. 

f. The sex ratio seemed to be 1:1, with 18 females and 19 
males. 

In contrast to this, 16 specimens of Trichobius major, from 
Fort Hood, Texas (Host: Myotis vclifcr), collected by H. E. 
Evans and E. G. Matthews on July 1, 1956, were also examined. 
According to Dr. Evans these flies were found on the walls of 
the cave, near the bats. The results were as follows : 

a. The transverse suture was dark in 12 of the 15, but light 
in three. However, the other three were in teneral condition, 
and I assumed that this line would darken on maturation. 

b. The distance the median line extended to the transverse 
suture on the mesonotum varied from .7 to 1.2, with a mean of 
1.1, and a standard deviation of .16. 

c. The number of bristles on the scutellum varied from 6 to 
9, with an average of 7.75, and a standard deviation of .68. 

d. The number of eye facets varied from 6 to 9, with a mean 
of 7.81, and a standard deviation of .63. 

e. Pubescence ranged from very sparse to very dense. 

f. This sample contained 8 males and 8 females. 

The Texas population is probably much closer to the center 
of origin and has not been as long isolated from the rest of the 
Trichobius group, thus has not had fixation of characters to 



Ixviii] ENTOMOLOGICAL NEWS 239 

such an extent as the West Virginia group. I would like to 
examine specimens from Kansas, where both species are known 
to occur in the same caves, and even on the same individual bat 
(Jobling, 1949). I would also like to know the extent of the 
range of the nearctic Trichobiits (corynorhini and major} east 
of Kansas, and whether it is continuous with the range of 
Corynorhinus between Kansas and West Virginia.

A New Parasitic Ant of the Genus Monomorium 

from Alabama, with a Consideration of the 

Status of Genus Epixenus Emery 

By W. L. BROWN, JR., and E. O. WILSON, Harvard University, 
Cambridge, Massachusetts 

The specimen described below was found in a nest of Mono- 
morium minimum (Buckley) at Tuscaloosa, Alabama. Al- 
though we have only a single example, the characters are so 
distinct that it is evident that we have here another aberrant 
inquilinous species of the kind now becoming almost a common- 
place discovery among the Myrmicinae. It has become the 
custom to consider parasitic forms of this degree of differentia- 
tion from the host species as "new" genera in almost every case 
found, but we shall give reasons below to show that the desig- 
nation of new generic names for myrmicine parasites has been 
a greatly overworked practice, due for critical review. 

Monomorium metoecus sp. nov. 

Holotype ergatogyne : TL 3.0, HL 0.67, HW 0.54, pronotal 
W 0.41, WL (alitrunk L) 0.88, petiolar W 0.35, postpetiolar 



240 ENTOMOLOGICAL NEWS [Nov., 1957 

W 0.36, W first gastric tergite, somewhat collapsed and widened 
0.93 mm. Cephalic index 81, scape index 93. W pronotum 
0.41, W petiole 0.35 mm. 

Head quadrate, without clypeus just about as long as broad; 
sides nearly parallel (very slightly narrowed behind eyes), 
feebly convex ; occipital margin transverse, straight in full-face 
view ; occipital angles gently rounded. Clypeus convex behind, 
the median lobe bicarinate, the carinae continued as two acute 
teeth, each tooth longer than broad at base and inclined very 
slightly mesad. Space between teeth semicircularly excised, 
impressed. Compound eyes intermediate in size between those 
of the worker and female of M. minimum, greatest diameter 
0.12-0.13 mm. Antennal scapes slender, curved gently flexad, 
gently incrassate toward tips; exposed length 0.50 mm.; when 
laid straight back, apices surpassing the occipital border by 
less than the apical scape width. Funiculus like that of M. 
minimum, but a little more slender. Segment I long and slender, 
II-VIII small, as broad as long, or broader; IX, X, and XI 
forming a distinct club, IX and X subequal, both longer than 
broad; XI (apical segment) longer than IX and X taken to- 
gether. Mandibles with 4 teeth, increasing in size apicad. 
Minute vestiges of ocelli present, but exceedingly indistinct, the 
anterior one connected to clypeus by a feeble sulcus. The head 
in all respects is intermediate between that of the worker and 
the female of Monomorium minimum, except for the longer 
clypeal teeth (reminiscent of those of M. viridum Brown) and 
the slender antennae. 

Form of alitrunk, petiole, postpetiole and base of gaster as 
shown in fig. 1. Points of greatest interest are the higher and 
more convex promesonotum and propodeum (as compared to 
the M. minimum worker), the deep metanotal groove, and par- 
ticularly the curiously hypertrophiecl nodes of petiole and post- 
petiole. The postpetiole is produced on each side below as a 
subacute conule, each conule bearing at its summit a spiracle. 
Gaster broad and somewhat collapsed.

Integument smooth and shining, with scattered inconspicuous 
piligerous punctures. Frontal lobes and extreme anterior cor- 
ners of head longitudinally striate. Striate areas of alitrunk 
indicated in the figures, as well as the reticulostriate parts of 
the postpetiole. Center of mesonotum with a small, transversely 
oval pit or puncture, the detailed structure of which cannot be 
made out.

view, and B. dorsal view of alitrunk, petiole, postpetiole and base of gaster. 
Drawing by Nancy Buffler. 



Pilosity abundant, fine, whitish, erect, uneven in length and 
widely distributed over head, scapes and body. Legs with 
dilute pubescence of fine appressed hairs. Pilosity intermediate 
in abundance and conspicuousness between that of the host spe- 
cies workers and queens. Color dark reddish-brown, to the 



242 ENTOMOLOGICAL NEWS [Nov., 1957 

naked eye appearing blackish ; legs, antennae and mandibles tan, 
shading to yellowish on tarsi. 

The holotype, a unique, was taken in a colony of Monomorium 
minimum (Buckley) (sensu Creighton) nesting under the loose 
bark of a living pine tree, just above the ground level, in dis- 
turbed open pine woods called "Smith Woods," on the Univer- 
sity of Alabama campus at Tuscaloosa, Alabama (E. O. Wilson 
leg., No. M-178). In the bark of the same tree was found a 
nest of Leptothorax bradleyi Wheeler. The host Monomorium 
nest contained numerous workers, brood, and at least two nor- 
mal dealate females of the minimum, the host species ; both 
females are preserved with workers under the number M-178 
in the Museum of Comparative Zoology, which is also the 
depository for the M. metoecus type. 

With the exception of the very aberrant petiole and post- 
petiolar structure, plus other minor details of sculpture, etc., 
M. metoecus is exactly intermediate in every detail between the 
worker and female castes of M. minimum. In fact, if it were 
not for the form of the nodes, the new species might well have 
been taken for an ergatoid or pseudogyne of minimum; worker- 
female intermediates are very commonly met with among the 
species of Monomorium, with or without dealate queens, and in 
quite a few species the ergatogyne is the only functional queen. 
From these facts, it is clear that the ergatoid condition is in 
itself no generic character. 

This raises the question of the relationship of Monomorium 
to Epixcnus Emery. Epixenus was originally based on an 
ergatogyne found in the nest of Monomorium venustum Andre 
in Palestine, and on a doubtful male from Crete, taken sepa- 
rately (Emery, 1908). Forel (1910) added E. biroi, based on 
an ergatogyne found with M. crcticum Emery, a member of 
the salomonis complex (referred to salomonis as a subspecies 
by Emery in 1922) from Crete. These ergatogynes differ from 
Monomorium ergatogynes only in the form of the petiolar and 
postpetiolar nodes, which are more than usually anteroposte- 
riorly compressed, and therefore tend to be somewhat scale-like. 
However, this characteristic shape of the nodes is more a matter 



Ixviii] ENTOMOLOGICAL NEWS 243 

of degree than of absolute qualitative difference, and other 
Monomorium females can be found that more or less approach 
the condition of the Epixenus so far as the nodes are concerned. 
M. metoecus, in fact, has the postpetiolar node more aberrant 
in form than in any of the Epi.reniis species. From these facts 
alone, it would seem that Epixenus is at best very doubtfully 
distinct from Monomorium at genus, or even at subgenus, level. 

Against this background, we can consider the recent contri- 
butions by Bernard (1952, 1955) to the taxonomy of Epixenus. 
Bernard first described E. guineensis from workers taken in 
West Africa, and then, in his 1955 review of Epixenus, he de- 
scribed E. algiricus from workers and females from each of a 
series of colonies taken in Algeria. The figure of the female 
does not show clearly whether wing stumps are present or 
absent, though the alitrunk is very narrow and like those of 
some ergatogynes of other species ; Bernard says only that the 
females are "reines desailees" taken in the nests, and the situa- 
tion seems to make it fairly certain that these females are not 
just parasites in the nest of a host species represented by the 
E. algiriciis workers (though the parasite hypothesis is not yet 
entirely to be discarded until a larger number of nests can be 
examined). Although Bernard emphasizes in his description 
and figures (especially fig. Id) the scale-like structure of both 
nodes, our comparison of two workers from the algiricus type 
series with other workers of the genus Monomorium indicates 
that algiricus is only very slightly more extreme in this char- 
acter than are workers of some other species of Monomorium, 
among which are M. hesperimn Emery and M. creticum Emery. 
It seems to us that on the basis of worker characters alone, algi- 
ricus, creticum and hesperimn could scarcely be put into differ- 
ent species-groups, let alone genera! And it must be remem- 
bered that E. biroi Forel was described from the nest of M. 
creticum, which suggests that the relationship of these two 
forms needs to be reexamined, keeping in mind the possibility 
that biroi may be just an ergatoid form of creticum. 

In discussing the biology of algiricus, Bernard makes clear 
that this species usually nests independently of other ants, and 



244 ENTOMOLOGICAL NEWS [Nov., 1957 

he believes that in the rest of the cases, it is associated only as 
a kind of thief-ant with other ant species (other species of 
Monomorium are supposed to follow lestobiotic habits, e.g., 
M. andrei fur Forel). This information eliminates the supposed 
parasitic habits of Epixenus as a group character, even if such 
habits were ever considered to define a genus in this case at a 
time when the Epixenus workers were still unknown. 

Consideration of the above details will, we think, show that 
what has been considered to constitute a distinct genus, Epi- 
xenus, is in fact nothing more than a heterogeneous collection 
of a few species of Monomorium that tend to have the nodes 
more strongly compressed than usual for the genus. Some of 
these species (e.g., andrei} may represent workerless ergato- 
gynous inquilines derived from their host species, while others, 
such as algiricus, seem to be rather average species of Mono- 
morium. The larval characters described for algiricus by Ber- 
nard may be a little unusual for Monomorium, but we must 
remember that only a triflng fraction of the Monomorium 
species have been described in the larval state, and the other 
Epixenus larvae also remain unknown. We offer below the 
formal synonymy of Epixenus with Monomorium, and the new 
combinations necessary after this change.

Ixviii] ENTOMOLOGICAL NEWS 245 

We are deliberately entering this name in Monomorium, even 
though it is preoccupied there, because we do not wish to pro- 
pose a new name where the distinct possibility exists that the 
E. biroi of Forel, 1910, is only the female caste of Monomorium 
creticum Emery, with which it was found. The same applies 
to the male originally described as Epixenus creticus by Emery 
(see below).

of Monomorium creticum Emery, 1895.

This is an aberrant species, with unusual conformation of pro- 
podeum and nodes, and very small in body size. Its relation- 
ship to the other species of Monomorium requires further study. 

Monomorium algiricum (Bernard) comb. nov. 
Epixenus algiricus Bernard, 1955, Insectes Sociaux, 2 : 274, 
worker, female. 

We have made no study of the species of Monomorium in 
order to exhaust the possibilities of synonymy between algiricum 
and the numerous small forms of the genus occurring in North 
Africa and southern Europe. However, a cursory check of the 
Museum of Comparative Zoology collections revealed no ex- 
actly similar species. M. hesperium and M. creticum Emery 
(I) seem to be closely related. 

In checking casually through some of the now rather large 
number of parasitic myrmicine genera, most of which are 
"satellites" of large genera such as Myrmica, Solcnopsis, Mono- 
morium, Tetramorium, Crematogaster, and especially Lepto- 
thorax, one is impressed by the flimsy nature of the characteri- 
zations upon which the parasite names rest. In some cases, 
such as Teletitomyrmex or Ancrgatcs, little doubt about generic 



246 ENTOMOLOGICAL NEWS [Nov., 1957 

status can be entertained, but in many of the rest, it seems that 
the known or presumed parasitic habits of the ants have been 
given undue weight at the generic level. When rigorous taxo- 
nomic investigation of these satellite genera is begun in earnest, 
it seems likely that many of them will go the way of Epixenus.

New Records of Plecia (Diptera: Bibionidae) 

By SELWYN S. ROBACK, Assistant Curator, Department of 

Limnology, Academy of Natural Sciences of 

Philadelphia 

The specimens herein reported are all in the collection of the 
Academy of Natural Sciences of Philadelphia. The specimen 
of Plecia alacris Curran was taken by the author during the 
course of the Catherwood Foundation Peruvian Amazon Ex- 
pedition in 1955. The remaining material was already in the 
Academy's collection. The author would like to acknowledge 
gratefully the gift of a male paratype of P. alacris by Dr. C. H. 
Curran of the American Museum of Natural History. 

Plecia (Plecia) alacris Curran 

Of this species, previously recorded from British Guiana and 
Paraguay, a single male was taken by the author at Iquitos, 
Peru, October 20, 1955. This specimen has been compared 
with the paratype. The description of the species is rather 
brief, and hence some additional descriptive material is herewith 
presented. 

The male antenna is nine segmented, fig. B, with segments 
four eight as wide as long and about equal in length. The 
maxillary palpus is four segmented with the segments in the 
ratio of 1.4: 2.0: 2.1 : 3.3. The sternopleuron bears a patch of 
blackish hairs above its middle. The femora are thickened 
apically and the tibiae swollen in the basal half. The tarsal 
segments of the foreleg are in the ratio 6.5 : 2.5 : 1.7 : 2.0. Vein 
R 5 of the wing (fig. A) curves slightly upward to meet the 
costa rather than curving down with it. The median process of 
ninth sternum is distinctly truncate apically and is upcurved at 
its apex (fig. C). 

Plecia (Plecia) americana Hardy 

A single male from Encero Vera Cruz, S. of Jalapa, Mexico, 
July 17, 1932 (Hobart Smith). A single paratype is in the 



248 ENTOMOLOGICAL NEWS [NOV., 1957 

Academy's collection (Philadelphia Academy of Science in 
Hardy, 1940). 

Plecia (Plecia) curvistylata Hardy 

This species was described by Hardy (1942) from Cuerna- 
vaca, Mexico. There is in the Academy's collection a series of 
eight males and one female collected July 4, 1932 by Hobart 
Smith from near Taxco, Guerrero, Mexico, which is close to the 
type locality. Since the species was described on the basis of 
only two males, there is offered here a brief description, and 
figures of the genitalia (figs. D, E) of the female in the Acad- 
emy's collection. The female genitalia, particularly the form of 
the eight sternite, supports Hardy's placement of this species 
with the collaris group (see fig. 135B in Hardy, 1945). 

Female. 5.4 mm. long; antenna 10 segmented: flagellar seg- 
ments 2-7 short and broad (1.66 X as wide as long) ; antennae, 
palpi, thoracic pleurae, sternum, and abdomen dark brown; 
mesonotum red-orange ; darkened anteriorly but not as distinctly 
as in the male; wing 6.0 mm.; lightly infuscated ; stigmal area 
not too clearly differentiated; R : . + 4 not as sharply curved as in 
male ; halteres black, shaft brownish ; female genitalia, figs. D, E. 

Plecia (Rhinoplecia) nearctica Hardy 

A common species represented in the Academy's collection by 
a series of 24 males and 22 females collected by Rehn, Pate, and 
Rehn, September 4, 1937 between Beaumont, Texas and New 
Iberia, Louisiana. There are also two paratypes from Hardy's 
original series in the Academy's collection (listed as Philadelphia 
Academy of Science in Hardy, 1940).

Notes and News in Entomology 

Under this heading we present, from time to time, notes, news, and 
comments. Contributions from readers are earnestly solicited and will 
be acknowledged when used. 

Meetings of the American Entomological Society. Years 
ago, the NEWS contained a section entitled "Doings of the Socie- 
ties," which reported the minutes or other matters of interest 
from this and other societies. Believing that even now there 
may be some general interest in such things, it may be recorded 
that at our meetings during the past year, in addition to the 
minor reports and discussions by those in attendance, there was 
always an invited speaker of prominence. For the nine meet- 
ings, Sept. 1956 to June 1957, we enjoyed the following, each 
an entomologist of highest competence in the particular field : 
Dr. RANDALL LATTA, on insect problems in marketing agricul- 
tural products ; Dr. SELWYN S. ROBACK, on phylogenetic as- 
pects in Diptera; Dr. WALTER FLEMING, on an entomological 
trip to South America; Mrs. MARGARET M. GARY, on effects of 
geographic isolation on the evolution of the Sphingidae; Dr. 
BAILY B. PEPPER, on teaching and research at Rutgers Univer- 
sity; Mr. JOHN WILCOX, on the biology and control of ticks; 
Dr. NEAL A. WEBER, on fungus cultures from ant's nests ; Mr. 
O'DEAN L. KURTZ, on identification of fragments in cereals. 

For the current year, the program includes, for September, 
Dr. THOMAS E. SNYDER, on termite biology, control, trends ; 
for October, probably Dr. GEORGE H. BRADLEY, on some phase 
of the malaria, or the typhus problem in the U. S. ; for Novem- 
ber, Dr. HUBERT FRINGS, on the sounds of insects ; for Decem- 
ber, Dr. JOHN W. H. REHN, on pest control in the U. S. Navy; 
for January, Dr. HARRY S. SMITH, on plant pest problems in 
the northeast ; and for February, Mr. R. C. BROWN, on forest 
insect research in the northeast. 

The Society welcomes visitors. All with an interest in in- 
sects are cordially invited to attend our meetings, especially ento- 
mologists from other parts of the country who happen to be 
passing through Philadelphia. The meetings are at 7.45 P.M. 
at the Academy of Natural Sciences, s.w. corner of 19th and

The International Trust for Zoological Nomenclature an- 
nounces the immediate publication in book-form of the first 
instalment of each of the "Official Lists" of valid zoological 
names and of the corresponding "Official Indexes" of rejected 
and invalid names, together with the first instalments of the 
"Official Lists" of works approved as available for zoological 
nomenclature and of the "Official Index" of rejected and in- 
valid works. The categories of names covered by these "Lists" 
and "Indexes" range from specific names to ordinal names. The 
total number of entries contained in the instalments now to be 
published amounts to about five thousand. These entries have 
been promulgated from time to time by the International Com- 
mission on Zoological Nomenclature in individual "Opinions" 
and "Directions" but owing to the large number of documents 
so involved it has become increasingly difficult for specialists to 
ascertain what names have so far been registered under this 
system. This difficulty will completely disappear on the publi- 
cation of the instalments now in the press, each of which will be 
supplied both with a full alphabetical index and also with alpha- 
betical indexes arranged by major groups. 

All enquiries in regard to the above publications should be 
addressed to the International Trust for Zoological Nomencla- 
ture at its Publications Office (41 Queen's Gate, London 
S.W.7.). FRANCIS HEMMING.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuracschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other ; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

A New Species of Scorpion of the Vejovidae: 
Paruroctonus x mesaensis 

By HERBERT L. STAHNKE, Arizona State College, 
Tempe, Arizona 

Living specimens of Paruroctonus mesaensis have uniformly 
very pale yellow cauda, appendages and carapace. The pre- 
abdomen appears somewhat darker an effect, in the main, pro- 
duced by the darkish internal organs showing through the more 
or less translucent, dorsal exoskeleton. Because of this yellow- 
ish color and the rather long, slender body, the layman has often 
mistaken this scorpion for Centruroides sculpturatus Ewing, the 
Southwests' lethal scorpion. It is obvious that the fancied re- 
semblance is superficial since they belong to different families 
C. sculpturatus to the Buthidae, P. mesaensis to the Vejovidae. 
In addition to this, the sting of C. sculpturatus has proven lethal 
to children in good health up to the age 16 years, while the most 
severe reaction observed from P. mesaensis has been rather 
pronounced, non-ecchymotic but very painful swelling at the 
site of the sting.

DESCRIPTION OF HOLOTYPE: Carapace. Uniform light yel- 
low with crescent of dark pigment on median periphery of each 
eye. Some living specimens with entire median ocular tubercle 
permeated by black pigment ; others with diffuse area of brown 
pigment in the interocular triangle. Condition of holotype seems 
most common. Interocular triangle sparsely covered with coarse 
granules which become larger and more abundant posteriad. 
Lateral eyes three, which form approximately an angle of 120 
degrees. Median ocular tubercle prominent. Median groove 
begins as a broad depression on extreme anterior border, ex- 
tends as a shallow groove over ocular tubercle and ends as nar- 
row pit-like furrow and then bifurcates at right angles into two 
shallower depressions on most posteriad margin. 

Preabdomen: All segments covered with fine granulations. 
Segments 1 and 2 with few large granules scattered on extreme 
posterior and lateral margins. Large granules scattered over 
posterior half of segments 3 through 6. Large granules of seg- 
ment 7 primarily on ridges of four lateral keels. Intercarinal 
spaces with scattered large granules. Median keel as only in- 
distinct vestige on segments 1 and 2, becoming larger on other 
segments as it travels posteriad but never becoming a prominent 
structure and extending across only posterior half of each seg- 
ment with exception of 7th where its greatest prominence is at 
midway point. Large, lateral granules of last segment denticu- 
late and located on lateral edge of shelf-like lateral protrusion. 
Ventral abdominal surface free of large granules except for ex- 
treme marginal, denticulate granules and large granules forming 
two lateral keels on 7th segment. Second pair of lateral keels 
represented distad by a few granules. Intercarinal spaces of 7th 
segment with very few large and small granules. Ventral sur- 
face of other segments appears very finely punctate rather than 
smooth and shiny. Stigma narrow-elongate. Sternum sides 
sub-parallel ; with very deep median furrow in posterior half ; 
anterior third with large granules. Genital operculum partially 
divided into two separate halves. Pectines with more than 16 
subcircular, vaulted middle-lamellae ; fulcra moderate sized, 
teeth: 23/23. Some with 21 pectinal teeth. Most proximal

than wide. Segment IV shorter than carapace: ratio 1.10. 
Segments I-IV ventrally quite hirsute with moderately long 
bristles. 

Dorsal keels: Coarsely granular on segments I, II, and III ; 
sub-denticulate granules on IV. Large rounded granules on 
segment V. 

Superior lateral keels: Like dorsal keels but incomplete on 
segment V. Present on 0.4 of proximal end of segment and 
represented by moderate sized granules. 

Median lateral keels: Coarsely granular on segment I ; repre- 
sented by 4 or 5 large granules at distal end of segment II, and 
by 3 large granules at distal end of segment III; lacking on 
segments IV and V. 

Inferior lateral keels: Coarsely granular on segment I ; prom- 
inent on segment II but not distinctly granular ; granules definite 
on segment III and large well developed granules on segments 
IV and V. 

Median ventral keels: Not prominent and without granules 
on segment I ; distinct but smooth on II and III ; with large 
granules on IV and on V represented by one distinct keel with 
large granules. 

Intercarinal spaces: Few large granules on dorsal and dorso- 
lateral regions of segment I through III, lacking on segment IV 
and sparsely represented on inferior surface of segment V. 

Tclson: Elongated, tear-drop in shape and smooth with few 
large bristles. Two large bristles located ventrally at base of 
aculeus. Lighter in color than other segments. Aculeus 
slightly more than % length of telson. 

Chelicera: With (fig. 1)5 more or less truncated, uniform- 
sized teeth on inferior border of movable finger. These teeth 
vary in number from 2 to 5, sometimes several may be united 
to form a single very wide tooth. Two reddish, tubercle-like 
protuberances on inferior border of fixed finger. Some with .1 
such protuberances, which are sometimes denticulate.

ranged with large tooth separating each of the six clusters. 
Each large tooth flanked medially by large tooth except (on the 
movable finger) distad where there are two large flanking 
teeth (seven in all). Fixed finger has only five flanking large 
teeth plus one large flanking terminal tooth. Distance between 
median large teeth and lateral teeth increases progressively 
distad. A large bristle immediately posterior to each flanking 
large tooth except the two most distal ones.

P. mesaensis differs principally from P. gracilior (Hoffman) 
as follows : - P. mesaensis is uniformly light yellow whereas P. 
gracilior has a crescent-shaped spot in interocular triangle simi- 
lar to Hadrurus hirsutus. Also, the dorsal plates of the ab- 
domen show widespread dark spots on both sides of the middle 
line, which give a blackish tint to the plates. Pectinal teeth of 
P. mesaensis 32/32 ; P. gracilior, 26/28. The fourth caudal 
segment of the male P. mesaensis is considerably longer than 
carapace, while in P. gracilior this segment is a little shorter than 
carapace. 

On P. mesaensis the teeth on the ventral surface of the mov- 
able finger truncated and uniform in size ; P. gracilior has a large 
basal truncated tooth and 4 smaller teeth. Caudal keels more 
coarsely granular in general on P. mesaensis than on P. gracilior. 



The Occurrence of Salmacia longipulvilli in the 
Hawaiian Islands (Diptera: Larvaevoridae) 

By PAUL H. ARNAUD, JR., Entomology Research Division, Agri- 
cultural Research Service, U. S. Department of Agriculture, 

Washington, D. C. 1 

The parasitic fly Salmacia longipulvilli (Tothill) has not been 
recorded in the Hawaiian entomological literature, although it 
appears to be an immigrant species from America. It was 
present in the Hawaiian Islands as early as 1929. Since Sal- 
macia longipulvilli is similar in size to Chaetogaedia monticola 
(Bigot), the former has apparently been confused with monti- 
cola and remained undetected in collections. 

These two species may be separated on a readily visible struc- 
tural character of the head : S. longipulvilli has the facial ridges 
bare (except for several bristles immediately above and in as- 

- Hoffman described only the male of the species.

sociation with the vibrissae) ; while C. monticola has the facial 
ridges bristled on more than the lower half. 5". longipulvilli also 
possesses an orange-yellow abdomen with black base and apex 
and a median, occasionally broken, black longitudinal stripe on 
the dorsum of the abdomen. Females of longipulvilli tend to 
have more black on the abdomen than the males, having a 
broader median black stripe and more of the fourth, as well as 
the fifth, tergites black above. C. monticola in contrast has a 
grayish abdomen, with only slight traces of orange-yellow on the 
sides, and with the fifth tergite mostly orange-yellow. Figures 
1 to 5 illustrate the head, wing, and terminalia of the male of 
Salmacia longipulvilli.

Additional specimens are to be found in the Bernice P. 
Bishop Museum and, probably, in other collections in the Ha- 
waiian Islands. 

Host Data 

Morrison (1940) has reported A gro tis orthogonia (Morrison) 
(family Phalaenidae) as a host of longipulvilli in Saskatchewan. 
In the collection of the United States National Museum there 
are now eight specimens labelled as paratypes [No. 28,300] of 
longipulvilli [Tothill stated there were six]. An interesting 
feature of five of these specimens, which originated from Tempe, 
Arizona, "10-8-17" (H. L. Dozier), is that they bear the labels 
as having been "Reared from Fcltia onuc.ra," an important fact 
which was omitted by Tothill in reporting on the type series. 
The name Feltia subterranea (Fabricius) (family Phalaenidae) 
is the revised name for Fcltia annc.ro, according to Dr. E. L. 
Todd.

IV. Seasonal Distribution of the Black Fly, 

Simulium vittatum Zett. (Diptera: 

Simuliidae) 

By W. W. JUDD, Department of Zoology, University of Western 

Ontario, London, Ontario 

In the description of the Byron Bog (Judd, 1957) it was 
pointed out that one method of collecting insects in the bog was 
to make a circular sweep with an insect net, held at arm's length, 
through the tops of the bushes in the Chamaedaphnetum calycu- 
latae association. The net used was one with a rim twelve inches 
in diameter and the radius of the circle over which the sweep was 
made was six feet. A single sweep was made each day from 
May 15 to November 15 in 1956 and all the insects collected each 
day were sorted and counted. Among the insects so collected 
were black flies which were all identified as Simulium (Nco- 
simuliitm) vittatum Zetterstedt by Dr. D. M. Davies, McMaster 
University, Hamilton, Ontario. Three males and five females

are deposited in the collections of McMaster University and all 
other specimens are deposited in the collection of the Department 
of Zoology, University of Western Ontario. 

While the flies were in flight they were a considerable nui- 
sance to anyone collecting in the bog, for they flew against the 
face, crawled into one's ears and nose and scuttled along the 



264 ENTOMOLOGICAL NEWS [Dec., 1957 

crevices between the skin and clothing. At no time were they 
found to bite. Several authors who have investigated this spe- 
cies have concluded that 5\ vittatwm does not bite humans at all 
or does so only occasionally (Davies, 1950; Davies and Peterson, 
1956; Hocking and Pickering, 1954; Hocking and Richards, 
1953; Twinn, 1936; Twinn et al., 1948). 



J 




JUNE JULY AUG. SEPT. 

Seasonal distribution of males and females of Simulium vittatum Zett. 

During the period June 29 to September 10 seventy-five flies, 
7 3$ (9%) and 68$$ (91%), were collected by sweeping, the 
maximum number caught on one day being 7 on July 27 (fig. 1 ) . 
Males were caught between July 26 and August 16. The pre- 
ponderance of females is in accord with the findings of Davies 
(1952) and Twinn et al. (1948) who captured more females 
than males in sweep collections, although a sex ratio of 1 : 1 was 
found by Davies (1950) for flies emerging into a cage set on a 
creek bed. Davies (1952), in reporting on a study of 6". vitta- 
tum in Algonquin Park, records that few specimens were ob- 
tained by netting, with only a single male captured by that 
method. The period during which the flies were caught in the 
Byron Bog (June 29-September 10) is well within the period 
during which this species was found in flight and ovipositing 
(April to October) at Hamilton, Ontario, some ninety miles 
eastward from the Byron Bog (Davies and Peterson, 1956).

A Note on the Identity of Parorya valida Cook 
(Chilopoda: Geophilomorpha : Oryidae) 

By R. E. CRABILL, Jr., Division of Insects, United States 

National Museum 

Of the major geophilomorph families, Oryidae seems the most 
poorly represented in America north of Mexico. Indeed, only 
the ubiquitous Orphnaeus brevilabiatus (Newport) has posi- 
tively been reported within the United States, where it very 
likely was introduced with cargo from the tropics. Neither 
brevilabiatus nor any other oryid is known to be established 
here, which stands in striking contrast to the situation in the 
American tropics where a number of endemic genera and species 
occur. 

For this reason Cook's discovery in 1896 of an endemic new 
genus, Parorya, from Texas or Louisiana seems of extraordinary 
interest. Unfortunately his new form was inadequately de- 
scribed in an obscure publication x and consequently has gone un- 
noticed by nearly everyone for well over half a century. Al- 
though the Count von Attems cited Parorya in his roster of oryid 
genera in 1926, - he was unable to include it in his accompanying 
key to genera. In addition, the generic and trivial names are 
conspicuously absent in his celebrated 1929 world monograph 

iBrandtia, fasc. VII, p. 33, (1896).

of the order. 3 Thus he was aware of the existence of the name 
in the literature, but, confronted only with the vague and frag- 
mentary original diagnosis, he could not place Cook's centipede 
with confidence within the oryid system. 

Undiscovered for many years, the female holotype (U.S.N.M. 
Type Number 2363) recently was located in the myriapod col- 
lection of the United States National Museum. It is a specimen 
of the common western Mediterranean Orya barbarica (Ger- 
vais). 4 

All we know of this specimen's collection is that Schufelt cap- 
tured it either in Texas or Louisiana, where it must have been 
introduced with produce from the Mediterranean, a possibility of 
which Cook made no mention. 

Cook was well aware of its obvious similarity to the conspicu- 
ous and well-known barbarica, for his description is almost en- 
tirely concerned with postulated generic differences between the 
two. (In 1896 barbarica was the only known member of 
Orya.} He reported that in his specimen the apical article of 
the "genital palp," i.e., of the gonopod, is small but distinct, 
whereas that of Orya is rudimentary. Actually, Cook's speci- 
men is practically identical in this feature with North African 
specimens of barbarica. He described the spiracles of valida as 
being much longer and narrower than those of barbarica, but I 
have found the proportions of the former to fall within the range 
of variability of the latter. His attempt to distinguish between 
the two on the basis of stigmopleurite shape is invalid for the 
same reason ; the stigmopleurites of valida closely resemble those 
of older, rather than of young, barbarica specimens. 

On the basis of the original description, perhaps his most com- 
pelling argument rests upon the relative size of the two species' 
pregenital sternites/' He found that this sternite in barbarica 
is pronounced, and described it as rudimentary in valida. Ac- 

3 Das Tierreich, Lief. 52, (1929). 

4 Since valida, 1896 = barbarica, 1835, and each is the genotype of its 
genus by monotypy, Parorya Cook, 1896, is an objective junior synonym 
of Orya Meinert, 1870. 

5 Attems', rather than Verhoeff's or Broelemann's, terminology is used. 
See Attems, 1929, p. 26, fig. 35, label vpg.

tually, the two plates are identical. Cook's specimen had simply 
contracted in alcohol, telescoping its rear somites and thereby 
largely concealing the pregenital sternite beneath the preceding 
ultimate pedal sternite. 

Although Cook had not dissected the mouthparts, he sur- 
mised them to be the same in both forms : they are. In sum- 
mary, I am entirely unable to prove Cook correct and the pres- 
ent disposition of valida incorrect. Including the complexities 
of the pleural sclerites, no apparent detail presents any convinc- 
ing basis for considering valida as anything but an introduced, 
typical specimen of Orya barbarica. 

Finally, it is worth mentioning that this seems to be the only 
report of the presence of this gigantic North African species in 
the United States. 



Review 

DIE LARVALSYSTEMATIK DER BLATTWESPEN (Tenthredinoidea 
und Megalodontoidea) by Herbert Lorenz and Manfred Kraus. 
Abhandlungen zur Larvalsystematik der Insekten, Nr. 1. PP. 
vi + 339; figs., 435. Akaclemie Verlag, Berlin, 1957. Price: 
paper bd., DM 38. 

Compared with the first attempt at a larval classification of 
the sawflies (Yuasa, in 111. Biol. Monogr., 1922), this is a more 
extensive work. It refers most often to Benson's classification 
of imagines, but for the Nematinae, and for comparisons, both 
Yuasa and Enslin are considered. There are pages on collect- 
ing and rearing, on biology, morphology, and coloration. The 
main part gives keys to the categories from superfamilies down 
to species, provides diagnoses and biological notes on 236 
European species, and supplies a list of food plants. Recent 
classifications such as Benson's are largely confirmed, except for 
some genera in the Nematinae, and the tribes in certain sub- 
families. Where difficulties exist, larval studies often suggest 
solutions ; thus, the Dolerinae should remain a separate subfamily. 

Such works as this are much needed, for although fine work 
has been done on some, notably the aquatic, larvae, it is appalling 
to think of how much remains to be done by the increasingly 
scarce systematists. R. G. SCHMIEDER.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

A New Genus and Two New Species of Micro- 
lepidoptera from Japan (Gelechiidae) 

By J. F. GATES CLARKE, United States National Museum, 
Washington 25, D. C. 

The species described below were included in material sub- 
mitted by Dr. S. Issiki, Entomological Laboratory, Faculty of 
Agriculture, University of Osaka Prefecture, Sakai, Osaka, 
Japan. The new species, Chelaria sapindivora, adds another to 
the long list of Oriental species, and the new genus and species, 
Paralida triannulata, augments the rapidly growing list of 
Japanese microlepidoptera. 

PARALIDA, new genus 

Type of the genus: Paralida triannulata, new species. 

Head smooth; antenna simple, slightly thicker in male than 
in female, without pecten. Maxillary palpus short, not ap- 
pressed to tongue. Labial palpus with very large, expanded 
tuft divided roughly into three parts; third segment erect, 
slightly roughened posteriorly with loose scales. Thorax 
smooth. Forewing long, narrow, apex produced, termen 
emarginate, 12 veins; Ib furcate; 2 and 3 remote, both arising 
well before end of cell ; 4 from corner of cell ; 5 distant from 6 ; 
7 and 8 out of the stalk of 6, 6 to apex; 9, 10, 11 about equidis- 
tant, 1 1 from middle of cell. Hind wing without cubital pecten, 
termen convex, 8 veins; 2 remote from 3, 3 from before angle 
of cell ; 3 and 4 separate, 4 from angle ; 6 and 7 stalked ; cross- 
vein between cell and vein 8 complete. Hind tibia heavily 
clothed with long hairlike scales. Abdomen not spined.

2 ENTOMOLOGICAL NEWS [Jan., 1958 

Male genitalia: Symmetrical; harpe simple. Uncus and 
gnathos well developed. Vinculum weak. 

Female genitalia: Signum present. Ductus bursae mem- 
branous. 

In Meyrick's key (Genera Insectorum, 1925, fasc. 184) 
Paralida runs to Chelaria. Meyrick's Chelaria, however, is 
composite and needs refinement. The produced apex and the 
absence of scale-tufts of the forewing of Paralida will distinguish 
it from anything now included in Chelaria. 

This genus is similar to the Formosan Phrixocrita Meyrick 
but differs widely from it by the stalking of veins 6, 7, and 8 
and the absence of scale-tufts of forewing ; also by the greatly 
expanded tuft of the labial palpus. In addition, veins 2, 3, and 
4 of the forewing of Paralida are widely separated. 

Paralida triannulata, new species 

Alar expanse, 22-24 mm. 

Labial palpus buff; second segment with slight grayish suf- 
fusion outwardly in basal half. Antenna buff with three, con- 
spicuous black annuli near distal end. Head, thorax and fore- 
wing buff shaded with olivaceous ; head and thorax with an in- 
distinct, narrow, median fuscous line; between bases of veins 
10 and 11 a distinct brown spot followed by a yellowish streak 
in which are a few brownish scales at end of cell ; between veins 
8 and 9 a slender fuscous streak ; cilia buff with some grayish 
suffusion. Hind wing grayish-fuscous ; cilia buff with con- 
siderable grayish-fuscous suffusion anally. Legs buff, shaded 
with olivaceous ; distal tarsi fuscous.

Male genitalia: See figures (Slide No. 10612, type). Harpe 
greatly dilated distally. Gnathos a very strong hook, nearly 
as long as tegumen. Uncus nearly as long as vinculum, dilated 
distally ; aedeagus curved, pointed. 

Female genitalia: See figure (Slide No. 10613, paratype). 
Ostium elongate, oval. Signum a large thornlike process. 

Type: U.S.N.M. No. 63586. 

Type locality: Honsyu, Kinki, Ikeda (Em 16.ix.49) S.

Food plant: Melia azedarach var. japonica (G. Don) Makino. 
(From larvae in longitudinal fold of leaves.) 

Remarks: Described from the type male, one male and one 
female paratypes all with same data. Paratype 9 in U.S.N.M., 
the paratype $ is in Dr. Issiki's collection. 

I know of no other described gelechiid with which this strik- 
ing species can be compared. 

Chelaria sapindivora, new species 

Alar expanse 13-17 mm. 

Labial palpus sordid whitish ; second segment suffused 
ocherous inwardly, tawny-olive outwardly with some cinereous 
at apex ; third segment with four broad grayish-fuscous annuli, 
separated only by narrow lines of the ground color. Antenna 
grayish-fuscous annulated with dull tawny. Head, thorax 
and ground color of forewing grayish-fuscous, the scales tipped 
with cinereous ; thorax with a few scattered tawny-olive scales ; 
extreme costa of forewing tawny-olive except where ground 
color shows through ; on costa, five raised tawny-olive scale 
tufts mixed with grayish-fuscous and cinereous ; of the five tufts, 
that at basal fifth is large and conspicuous, that at middle mode- 
rate, and outer three inconspicuous, scarcely discernable in some 
specimens; near base of wing, in costal third, a small raised 
scale-tuft similar to the others ; three tawny-olive blotches, one 
at basal fifth, one at middle of wing, and another in apical third, 
the latter with spot of ground color in center ; cilia grayish- 
fuscous, tipped with cinereous. Hind wing fuscous, lighter

basally; cilia grayish-fuscous. Legs ocherous-white suffused 
and annulated with fuscous. Abdomen fuscous with a longi- 
tudinal, ocherous-white band ventrally. 

Male gcnitalia: See figures (Slide No. 10614, type). The 
left harpe is divided into three elements, the right into two. 
At their bases the harpes are closely involved with elements of 
the anellus, so much so that they appear as one structure. 
Around the distal edge of the uncus is a row of sharp, short 
setae. 

Female genitalia: See figures (Slide No. 10615, paratype). 
The large sclerotized area surrounding the ostium characterizes 
this species. Inception of ductus seminalis slightly posterior 
to bursa copulatrix. 

Type: U.S.N.M. No. 63587. 

Type locality: Honsyu, Kinki, Nisinomiya (Em. 16.vi.1949), 
S. Issiki. 

Food Plant: Sapindits mukurossi Gaertn. (tieing leaves). 

Remarks: Described from the type male, one male and two 
female paratypes as follows: Nara (J\ 18.vi.1956; 5> 19.vi. 
1956) : 5, same data as type (14.vi.1949). One $ and one $ 
paratypes in U.S.N.M., and one <$ paratype in Dr. Issiki's 
collection. 

This species is very similar to C. paroctas Meyrick from 
Ceylon, but differs by the large, unbroken dark area before 
middle of forewing, the greater expanse of the tawny areas and 
the darker hind wing. The uncus of paroctas is clothed with 
numerous fine hair-like setae, while that of sapindivora has a 
marginal row of short, stout setae. The female of paroctas is 
not known, but the female of pctrinopis Meyrick, from Osaka, 
Japan, appears to be closely related to sapindivora. The most 
conspicuous differences are the slender, membranous ductus 
bursae and broad, sclerotized area surrounding the ostium of 
sapindivora compared to the stout, partly sclerotized ductus 
bursae and narrowly sclerotized area surrounding the ostium 
of petrinopis.

Designation of a Lectotype of Goniodes minor 
Piaget (Philopteridae : Mallophaga) 

By K. C. EMERSON, Stillwater, Oklahoma 

In 1880, Piaget (Les Pediculines, p. 256, pi. 21, fig. 3) de- 
scribed and illustrated Goniodes minor from specimens collected 
from Columba tigrina = Strcptopelia chincnsis tigrina (Tem- 
minck), Columba bit or quota = Strep top elia bitorquata (Tem- 
minck) and pigeons domestiques = Columba livia "domestica." 
The name is preoccupied by Goniocotes minor Piaget, 1880 (p. 
241) = Goniodes minor (Piaget), 1880 (p. 241). Johnston 
and Harrison, in 1912 (Proc. Royal Soc. Queensland, vol. 24, 
p. 19), proposed Goniodes piageti as a nomcn novum for 
Goniodes minor Piaget, 1880 (p. 256). 

Specimens from each of the hosts mentioned by Piaget have 
been examined. The forms are not conspecific, but all belong 
to the present genus Coloceras Taschenberg, 1882. I hereby 
designate as lectotype of Goniodes minor Piaget, 1880 (p. 256), 
the male specimen on slide no. 987 of Piaget's syntypes in the 
British Museum (NH). The lectotype and two female syn- 
types on this slide have the collection data "Columba tigrina." 
This form is the larger of the two species of Coloceras normally 
found on Streptopelia chincnsis tigrina (Temminck). The fe- 
male syntypes agree with the description and illustration of 
Coloceras chincnsc (Kellogg and Chapman), 1902 (J. N. Y. 
Ent. Soc., vol. 10, p. 160, pi. 13, fig. 5) ; and in all probability 
is a synonym of that species.

Nomenclatural Notes on Proatta and Atta (Hym. : 

Formicidae) 

By NEAL A. WEBER, Swarthmore College, Swarthmore, 

Pennsylvania 

As a result of studies * in the three chief European collections 
of fungus-growing ants 2 synonymies and other changes are 
clearly indicated. Most of the several hundred forms in the 
literature were described by Emery, Forel and Santschi and 
their collections are in excellent condition. 

Field work and laboratory studies of living colonies have 
provided information on variability within a species that was 
not available when descriptions were first published. It has 
become clear that much variation even within a nest series is 
normal and that many species have a considerable range within 
the Neotropical Region.

Proatta butteli Forel 

1912. Proatta butteli Forel, Rev. Suisse Zool. 20: 769 

The types remaining in the Forel collection and two pins in 
the Santschi collection were examined. All were from Singa- 
pore and collected by v. Buttel. One of two types in the Forel 
collection carried the additional information "Soengi Bandan, 
26. iv. 1912, v. Buttel No. 403." 

While it is true that Proatta buttelli is strikingly like an attine, 
this is taken here to be an example of convergence in worker

of Dr. Delfa Guiglia. Their cordial reception of the author is appreci- 
ated.

morphology and not necessarily an indication of phylogenetic 
relationships. The spinosity is especially like that of Myco- 
cepurus, and another and unrelated ant with comparable spin- 
osity is Orectognathus antcnnatus of New Zealand. Proatta 
butteli differs markedly from attines in having the clypetis pro- 
duced as an angular lobe, which is impressed in the middle and 
with lateral carinae, and in having a single, large median spine 
on the basal surface of the epinotum anterior to the usual epi- 
notal spines. The antenna of the worker is 12-segmented and 
the anterior tarsi are not dilated. 

There is no evidence that Proatta is a fungus-grower and it is 
not considered here to be a member of the Attini. At the present 
time this tribe is known only to be New World in distribution.

The most conspicuous and economically important fungus- 
growing ants are those belonging to the genus Atta. The taxo- 
nomic studies by Gongalves (1942) and Borgmeier (1950) and 
the biological studies by Autuori and others in recent years have 
aided considerably in our understanding of this genus. An 
examination of certain types in the European collections makes 
it possible here to fix the identity of several forms. The studies 
of Gonc.alves and Borgmeier must be consulted for the 
genus itself. In as homogeneous a group of species as Atta 
contains, the present author is reluctant to use subgenera. 
When one considers the tribe as a whole, Atta forms the most 



Ixix] ENTOMOLOGICAL NEWS 9 

compact group of species and the similarities are overwhelmingly 
more significant than the differences. 

Examination of the three European collections confirmed the 
general South and North American views on the identity of the 
two Linnean species, cephalotes and sexdens. Both appeared to 
have been described from Guiana (probably Surinam) speci- 
mens. The ecological distribution of the two in British and 
Venezuelan Guiana has been described (Weber, 1946, 1947). 
The typical cephalotes has been considered to occur here and in 
Trinidad. The soldier is large and conspicuously shiny on the 
occiput. Media and minor workers are shiny and a concolorous 
pale ferruginous. The typical sexdens is absent from Trinidad 
but Panama specimens appear identical to the Guiana specimens, 
a range markedly greater than indicated on Eidmann's maps 
(1935, 1937). 

Atta cephalotes ssp. isthmicola Weber 

1941. Atta cephalotes subsp. isthmicola Weber, Rev. de Ent. 
12: 127 

While this form may be a synonym, the Emery, Forel and 
Santschi collections do not contain any types that are clearly the 
same. The most striking characters are the bicolored and shiny 
integument of the worker, the thorax being a distinctly darker 
ferruginous than the head and gaster. Dead as well as living 
ants show this clearly and parts of colonies maintained in the 
laboratory for many months on several occasions do not change 
in this respect. 

The distribution of isthmicola includes the Cerro Campana 
some 50 miles southwest of Panama City, Panama, an area 
visited through the courtesy of Graham B. Fairchild and Carl 
M. Johnson. Above 2,000 feet in forested areas the ants build 
large nests in the clay soil. Males and females were secured 
by Dr. Fairchild and Ratibor Hartmann in May, 1957. The 
1938 type colony on Barro Colorado Island disappeared before 
1954 and the site is occupied by the very different Atta colombica 
tonsipcs.

Atta cephalotes ssp. lutea Forel 

1893. Atta lutea Forel, Ann. Soc. Ent. Belg. 37 : 587 

The type series in the Forel collection consisted of 15 pins, 
two being designated as types, the remainder as cotypes. All 
were collected by Jeffreys in Barbados. There is no maxima 
worker or soldier but workers of various sizes smaller than the 
maxima. All are uniformly pale brownish yellow and finely 
punctate on the head. A pin of three workers (media to 
maxima) in the American Museum of Natural History and one 
secured by the author through exchange with Dr. Ferriere are 
of this type series. They have the same characters as above. 

Contrary to the allocations of this as a separate species by 
more recent workers, it appears to be no more than a subspecies 
of cephalotes. It would seem to be a mutant developed from 
cephalotes on the pale coral sand of this small island. Perhaps 
it was introduced as typical cephalotes by way of the abundant 
shipping between Barbados and Trinidad and Demerara sev- 
eral centures ago. I collected typical cephalotes in all parts of 
Trinidad and do not believe that lutea occurs there. 

Atta cephalotes ssp. opaca Forel 

1904. Atta cephalotes var. opaca Forel, Rev. Suisse Zool. 12 : 
31. 

A single pin in the Forel collection, marked "Typus," is of a 
soldier from St. Antonio, Colombia, collected by Forel. The 
anterior lateral pronotal spines are reduced to mere humps and 
the anterior median ocellus is bipartite. It agrees perfectly 
with the specimens I took at Rio Force (Lat. 6 40' N., Long. 
75 10' W., 3,400 ft.) Colombia in 1938, representatives of 
which were determined as opaca by Gonqalves (1942, p. 345). 
He gives the range of the subspecies as Colombia, Bolivia and 
Brasil. Borgmeier (1950, p. 258) adds Peru. 

Dr. Ferriere during my visit translated the original descrip- 
tion as follows, commenting that the language was not entirely 
clear : 

"var. opaca n. var. The rear of the head is dull, and the 



Ixix] ENTOMOLOGICAL NEWS 11 

tufts of hair on the vertex are more dense and reclinate. Al- 
though strongly visible, this variety is insignificant and incon- 
stant. I have collected it beside the typical form at St. Antonio, 
in Colombia." 

If the last statement indicates the actual situation, opaca may 
be a form originating not through geographical isolation but in 
situ through mutation. An alternative explanation is that, while 
opaca may have originated in the conventional manner (i.e. 
geographical isolation), it later spread to the territory of typical 
cephalotes. Both factors may be involved in the presently un- 
clear distribution of Atta. 

Atta cephalotes ssp. polita Emery 

1905. Atta cephalotes subsp. polita Emery, Mem. Accad. Sc. 
1st. Bologna 2 : 18 

There are five pins in the Emery collections. Four of the 
five are labelled "Maipiri, Boliv., Staud." and one pin with the 
largest ant bears the identification "A. cephalotes var. polita 
Emery." All five carry a tiny green square of paper which 
doubtless signifies type material. In the original description 
the only specimens available was a series of small workers 3.5- 
6.5 mm. in length sent by Staudinger and Bang-Haas from 
Mapiri, Bolivia. Emery made his comparisons with workers of 
equal size of the typical form. 

The ants clearly are a cephalotes form and should not have 
been described without the maximum caste. The largest ant, 
a medium-sized media, has the bicoloration and shininess sug-

not listed by Vecht (1957) in his description of Guerin types 
although syntypes of Atta insularis are. During the past cen- 
tury various dull-colored specimens have been referred to this 
species but all such identifications should be suspect. In the 
original description only workers were mentioned and these had 
the head and prothorax glabrous. Compared with insularis 
they are paler, being reddish brown. His Atta Lcbasii, de- 
scibed also from Colombia and on the same page, has been con- 
sidered by the European myrmecologists to be the same as 
colombica.

Regardless of the uncertainty of what colombica may be, the 
ants that Santschi described as the variety tonsipes still exist 
and these represent the common Atta of the Panama Canal 
Zone. The Santschi collection has one pin marked type, a large 
worker (not a small soldier), from Bella Vista, Panama, 
"W.M.Wh." The initials refer to W. M. Wheeler and it was 
G. C. Wheeler (I studied under both of them) who collected 
and sent other specimens to Santschi. G. C. Wheeler has kindly 
loaned me other type material. For the original description 
Agua Clara and Colon ants were also used. The Santschi col- 
lection contains a soldier from France Field, Panama, Bierig 
4. vi. 30. 

Santschi had no way of determining that tonsipes was indeed 
a variant of colombica but, until evidence can be produced that 
his form is a synonym of something, his name is the best avail- 
able. At the present time it appears to be the only flourishing 
Atta on Barro Colorado Island, Canal Zone and has been used 
repeatedly by the author in experiments. 

Gongalves (1942, p. 346) has identified specimens that I took 
at Juan Diaz, Panama as tonsipes and they are the same form as 
that in the Canal Zone.

Some Records of Chilopods from Florida 

By RALPH V. CHAMBERLIN 

A collection of chilopods submitted to me for identification by 
H. A. Denmark of the Florida Plant Board contains representa- 
tives of the species listed below. Of these, those numbered from 
3 to 6 are interesting in being apparently the first records of the 
occurrence within the limits of the United States of four species 
otherwise widespread in the West Indies and other tropical and 
subtropical regions. The type of the new Crypt ops is for the 
present retained in the writer's collection. 

1. Cryptops denmarki new species 

The general color is light yellow of a slightly greenish tinge. 

Cephalic plate a little overlapping the first dorsal plate ; not 
sulcate. 

Prosternum with anterior margin nearly straight, narrowly 
chitinized. 

First tergite without a transverse or cervical sulcus ; two 
longitudinal sulci extending over entire length of the plate. 
The following tergites also with paired and complete sulci. 

Sternites without sulci or furrows. The last sternite with 
caudal corners rounded, the intervening margin nearly straight.

Report of Geophilus proximus in North America, 
with a Key to its Eastern North American Con- 
geners (Chilopoda: Geophilomorpha : 
Geophilidae) 

By RALPH E. CRABILL, JR., U. S. National Museum, 
Washington, D. C. 

Geophilus proximus C. L. Koch, 1847, is one of the most com- 
mon and widely-dispersed of western European geophilids. 
Reportedly favoring the more temperate areas, it has been col- 
lected from Scandinavia to the Mediterranean, as well as in 
Siberia and North Africa. Considering such ecological versa- 
tility and the ease with which geophilids or their eggs can be 
transported in soil, it is not surprising to learn at last of the 
presence of proximus in temperate North America. 

The single adult female, upon which this report is based, 
agrees closely with European conspecifics and was captured in 
August, 1955, in Cobden, Ontario, Canada, by Dr. Herbert W. 
Levi of the Museum of Comparative Zoology at Harvard Uni- 
versity. This is actually the second American specimen I have 
seen. The first, in the collection of the Museum of Compara- 
tive Zoology, was taken at quarantine in Philadelphia, Pennsyl- 
vania, where it was found in the soil about the roots of Amaryllis 
plants imported from Germany. In the light of all the evidence 
it seems safe to suggest that further collecting will show proxi- 
mus to be established at least in our northeastern coastlands, 
especially in long-settled areas and in the vicinity of greenhouses 
and nurseries. 

The following key will facilitate the identification of proximus 
and its congeners now known to occur in northeastern North 
America.

Lepidoptera Collected in the Tundra-Taiga 
Ecotone at Kotzebue, Alaska 1 

By PAUL R. EHRLICH, Chicago Academy of Sciences, Chicago, 

Illinois 

In late June of 1956 a small collection of Lepidoptera was 
made by the author at Kotzebue in northwestern Alaska. This 
locality, poorly known entomologically, is of particular interest 
because of its mixed arctic and subarctic fauna. Kotzebue 
(66 54' N, 162 37' W) is located at the tip of the unforested 
Hotham Peninsula. The peninsula is about 60 miles long, and 
lies between narrow Hotham Inlet on the north and east and 
Kotzebue Sound (an arm of the Chukchi Sea) on the west. 
The nearest dwarfed spruce forest is 10-15 miles north of 
Kotzebue in the valley of the Noatak River. 

The most prominent features of the Kotzebue flora are thickets 
of willows and dwarf alders which reach a height of more than 
six feet in protected places. In all other features the area has 
the aspect of typical tundra. 

The following species of Lepidoptera were taken (comments 
on the general ecological distribution of the species in North 
America in parentheses) :

It is evident from the above list that there are strong taiga 
elements in the lepidopterous fauna at Kotzebue. The presence 
in abundance of a weak-flying woodland butterfly such as 
Erebia disa (Ehrlich 1956, 1957) indicates that the limit of 
the coniferous forest in this area does not have the zoogeographic 
significance which it seemingly has in some parts of the Eastern 
Arctic. The mosquito fauna of the Kotzebue region (Barr 
and Ehrlich, 1958) included the typical taiga species Aedes 
fitchii (Felt and Young) and Aedes e.rcrucians (Walker) as 
well as tundra species. Similarly the avifauna showed distinct 
southern elements, with Gambel's white-crowned, tree and fox 
sparrows, robins and hoary redpolls occurring commonly (and 
nesting) in the company of birds more characteristic of the 
tundra such as semi-palmated plovers, savannah sparrows, 
Alaskan longspurs and Alaskan yellow wagtails. The marine 
bird fauna was arctic. 

The above data serve to emphasize the dangers of over- 
dependence on treeline (which is ordinarily considered synony- 
mous with the limit of coniferous forest) in the predicting of 
animal distributions. In the northern nearctic region it is often 
a useful tool, but its utility varies greatly from area to area and 
from organism to organism.

Notes on a New Habitat for Nerthra (Gelasto- 
coridae-Hemiptera) 

BY DAVID R. LAUCK x and WILSON G. WHEATCROFT 

The junior author and I recently collected the genus Nerthra 
in cowdung. One male adult of Nerthra mo-nni Todd and three 
nymphs were collected beneath cowdung in the vicinity of 
Guadalajara, Jalisco, Mexico, and a single female of the same 
group of Nerthra was collected in a dung paddy near Teguci- 
galpa, Morazan, Honduras. The latter specimen was found 
near the banks of a marsh, while the former specimens occurred 
in a dry area remote from water. They occupied paddies that 
were dry and encrusted externally but were moist internally 
and partially hollowed by dung beetles. 

Although Nerthra has not been found previously in dung, 
various species have been collected in arid habitats remote from 
water (reviewed by Todd 2 1955). The dung niche, which 
retains moisture, might serve as an evolutionary stepping stone 
from the moist shores to the dry habitat, or from dry to moist, 
whichever the case may have been. Future investigation may 
disclose more specimens and additional species of Nerthra in 
the dung niche.

Parasitism of Bees in Trap-nests by Leucospis 
affinis Say (Hymenoptera: Leucospidae) 

By J. T. MEDLER l 

The habits and life history of Leucospis affinis Say in nests 
of Osmia were reported by Graenicher (1906). Additional in- 
formation on the parasite in nests of Megachile and Hoplitis 
has been obtained during trap-nest research in Wisconsin. 

Eighty nests of Megachile relativa Cresson in sumac-stick 
traps were found parasitized by L. affinis during 1953-1956. 
The identity of the host was ascertained largely by the habitus 
and appearance of the nests, as only a small number of adult 
bees was reared for positive identification. In fifteen nests the 
parasites had emerged prior to collection, but a study of the 
empty nests showed that each cell had contained a parasite. In 
the other sixty-five nests, most of the cells were transferred 
singly to glass vials for rearing in the laboratory. The results 
are given in table 1. These data showed that probably more 
than 80 per cent of the cells in a nest were attacked by L. affinis, 
as most of the cells with mortality during rearing and those con- 
taminated by the secondary parasite, Melittobia chalybii Ashm., 
originally contained larvae of L. affinis.

The sex of the reared adults was associated with the sequence 
of cells in a nest, and the data from representative nests are given 
in table 2. It was found that female wasps almost invariably 
occupied the first cells, but all females or all males were some- 
times recorded. In most nests with mixed sexes, the male(s) 
followed a female series, but in nests 13, 15, and 16 a male was 
inserted in a female series. The high parasitism of the nests 
prevented any attempt to associate the sex of the parasite w r ith

the sex of the host bee. No information was obtained on multi- 
ple egg laying in a cell, as reported for Leucospis gigcts Fab. in 
Europe by Fabre (1914). 

The parasite had a summer and an overwintering generation 
in M. relativa nests. Trap-sticks placed in the field on June 28, 
1956 were collected on July 28 ; adults of L. affinis were obtained 
on August 22. Traps brought in from the field on July 21, 1955 
produced adult parasites on August 8. Most specimens of the 
summer generation were obtained in the middle of August. 
Nests collected in late August and September contained parasite 
larvae of an overwintering generation. These larvae were pre- 



Ixix] ENTOMOLOGICAL NEWS 23 

sumed to go into diapause, though cold treatment at 4.5 C. for 
5, 12, 19, 26, 30, and 33 days seemed to be equally effective in 
subsequently producing adults. The time-temperature studies 
were inconclusive because of contamination by M. chalybii in the 
incubators. The larval stage was 7-10 days and the pupal stage 
9-11 days at a constant temperature of 27 C. 

Records obtained in nests of Megachile inermis Provancher 
and Hoplitis producta (Cresson) are included here because an 
interesting relationship existed between the size of the host and 
the size of the parasite as indicated by head width measurements 
(0.1 mm.). A nest of M. inermis produced 3 females and 1 male 
of L. affinis with respective head widths of 34, 32, 30, and 25. 
Four nests of H. producta were each parasitized by Stelis sp., 
which in turn was attacked by L. affinis. One female and 3 male 
L. affinis reared from the Stelis cocoons had head widths of 19, 
17, 17, and 16. A study of head widths of L. affinis reared from 
M. relative, nests gave the following data: 134 females, 26.7 
1.92, range 19-30; 49 males, 24.1 + 1.78, range 19-27. M. 
inermis, which is a larger bee than M. relativa, produced larger 
parasites, whereas Stelis sp., which is smaller, produced smaller 
parasites. However, the size of parasites from the M. inermis 
and Stelis hosts were within the extreme range of the parasites 
produced on M. relativa. These data are consistent with previ- 
ous knowledge on size relationships of host and parasite. 

The successful attack on cells of various bees by L. affinis un- 
doubtedly is associated with the strong and relatively long ovi- 
positor of the female. Parasitized nests were obtained only in 
the sumac sticks, and not in the more substantial domicile-type 
described by Medler and Fye (1956). Probably there is a 
maximum thickness of wood through which the species can 
oviposit. The thickness of the walls of the sumac sticks was 
not measured during this study, but it should be a simple matter 
in future research to determine the thickness necessary to pre- 
vent L. affinis parasitism. 

Incidentally, bundles of trap-sticks frequently contained to- 
gether the nests of bees, eumenid wasps and sphecid wasps, but 
only the nests of bees appeared to be attacked by L. affinis. It 



24 ENTOMOLOGICAL NEWS [Jan., 1958 

is not known whether oviposition was restricted exclusively to 
nests of bees, or whether oviposition if it occurred in wasp nests 
resulted in mortality of the parasite.

Cressonomyia New Name for Plagiopsis Cresson 
Preoccupied (Diptera: Ephydridae) 

By PAUL H. ARNAUD, Jr., Entomology Research Division, 
U. S. Department of Agriculture 

It is unfortunate that the name Plagiopsis Cresson, 1934, 
which was proposed to replace the preoccupied Plagiops Cres- 
son, 1918, is itself preoccupied by two previous uses, thus re- 
quiring a further change of name. The name Cressonomyia

Notes on the 17-year Locust on Cape Cod in 1957 

By JOSEPH L. WILLIAMS, M.D., Philadelphia, Pennsylvania 

In a wooded area at Centerville, Massachusetts, near Craig- 
ville Beach, this locust was so numerous during the second 
week of June that children were collecting it by the quart. 
Nymphal exuviae were found clinging to buildings, trees, and 
many types of elevated objects in the woods. Emergence holes 
were noted in the ground of yards cleared of grass and shrubs, 
lawns, and in the woods. It was an unusually dry season here 
and whether this was an aid to its emergence survival is not 
known. 

The noise produced by the males was continuous beginning 
at about 10 A.M. daylight saving time and fading out about 
5 P.M. No sounds were heard after 8 P.M. The sound would 
make one think that he was not very far from a pond in which 
many frogs were singing. Matings were noted to occur during 
the singing period. Several mating pairs were placed on a 
large board to note length of the mating act from the time they 
were placed there. Careful handling did not disturb the mating, 
which continued from one and one-half to three hours. 
Several unmated males and females were placed in a large jar 
and some of these were later observed to be mating. 

In this particular area there are scrub-like oak, pine, and 
maple trees. Locusts were noted in the greatest number on 
oak, next on maple and the least or none on pine. An article 
in the local newspaper concerning this locust, "Cape Cod 
Standard-Times," Thursday, May 16, 1957, states that the fe- 
male locusts prefer apple and other fruit trees, oaks, hickory, 
locust, such shrubs as azaleas, delphinium and hardy phlox. 
An examination of the tender twigs in which the females had 
laid their eggs revealed the greatest number of punctures in 
oak, very few in maple, and none in pine. Damaged twigs, 
mostly oak, could be seen throughout the area with dead or 
dying leaves attached. 

At this particular site the locusts had disappeared by the 



26 ENTOMOLOGICAL NEWS [Jan., 1958 

middle of the last week in June. In some nearby areas how- 
ever, they were heard before they appeared in this area; and 
in some other nearby areas they were heard after they had 
disappeared elsewhere. This may be due to the fact that the 
locusts emerged in different areas at slightly different times. 



Notes and News in Entomology 

Under this heading we present, from time to time, notes, news, and 
comments. Contributions from readers are earnestly solicited and will 
be acknowledged when used. 

Colloquium on Zoological Nomenclature. A colloquium 
on nomenclature will be held in London in connection with the 
Fifteenth International Congress of Zoology. It will open on 
Wednesday, July 9th, i.e., one week prior to the opening of the 
Congress. It is hoped that this body will be able to relieve the 
Congress of the bulk of the work in the scrutiny of the draft of 
the revised Code and will be able to submit to the Congress 
agreed recommendations as to the text to be adopted. In addi- 
tion to the invitations already sent out, additional ones will be 
sent to any member of the Congress who expresses a desire to 
take part in its discussions but who has not yet received a sepa- 
rate invitation. FRANCIS HEMMING, Managing Director and 
Secretary, International Trust for Zoological Nomenclature, 28

Velia's Clock. The orientation behavior and the "internal 
clock" of insects have been attracting more and more interest. 
During the past year GEORG BIRUKOW and two co-workers have 
published four papers * on the behavior of the water strider, 

Velia. 

When placed on a dry surface, Vclia flees towards the sontJi, 
invariably and exactly. Just why always to the south remains

senschaften 44: 358-59, 474-75.

unexplained, but Birukow has shown that they use the sun or 
the blue sky as their compass. Thus, in early morning the sun 
would be at a great angle on their left. This angle diminishes 
to at noon, and in the afternoon the angle on the insects' right 
gradually increases. Indoors, in the presence of a fixed electric 
light bulb, they orient towards this light as if it were the sun, 
and alter the direction of their escape response in accordance 
with the time of day. 

In the winter, the angle through which the orientations oscil- 
late during these shorter days is adjusted to the arc of the sun 
at this season. In the summer or after exposure to 3 weeks of 
long "days" artificially, the amplitude is correspondingly in- 
creased. Velia may even adapt to the rhythm of a 10-hour day 
(5 hours light, 5 hours darkness), something not attainable in 
bees, which have an intrinsic rhythm. 

If Velia are tested after the usual hour of sunset, the angle on 
their right will now increase, and by midnight all individuals 
run due south (0) ; after midnight the angle on their left in- 
creases until 6 A.M. when they revert to their normal behavior. 
Thus, during the night, their internal time-mechanism runs in 
reverse, again differing from bees (see Ent. News 68: 132). 
Under constant illumination, or constant darkness, the amplitude 
gradually decreases, and the clock stops, so to speak, at 0. 

From these and from other observations, for which see the 
original articles in Zeitschr. f. Tierpsychol., and their English 
summaries, some conclusions can be drawn as to the working 
of the time-mechanism or "internal clock" in these insects, but 
the really essential features still remain a mystery. At least it 
does not depend on the intensity of the light, but only its dura- 
tion, and it appears independent of metabolism, for this varies 
with temperature, and Velia's clock runs accurately at all tem- 
peratures from 5 C. to 25 C. R. G. SCHMIEDER.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

A New Species and Subgenus of Kurodaia (Mal- 
lophaga: Amblycera) * 

By K. C. EMERSON, Still water, Oklahoma and ROBERT E. 

ELBEL, Department of Zoology, University of 

Oklahoma, Norman, Oklahoma 

The Ischnoceran genus Falcolius Clay, 1956, has been re- 
corded only from the falconets or pygmy falcons of south- 
eastern Asia. This genus apparently has no affinities with any 
known genera found on the remainder of the Falconiformes. 
The first results of a study made of several collections of ambly- 
ceran Mallophaga from this interesting group of birds are here- 
with reported. 

The amblyceran genus Kurodaia Uchicla, 1926, as presently 
defined, contains a number of species found on the Falconi- 
formes and Strigiformes. Examination of several undescribed 
forms from both host orders indicates that the present generic 
description is adequate, except for a new form found on the 
host genus Microhiera.v, the falconets. In general appearance, 
there is some doubt that the form should be included in the genus 
Kurodaia; however a majority of the generic characters nor- 
mally considered in the suborder indicate a definite relationship 
to this genus. Due to the significant differences between the 
form found on Microhierax and the remaining species of Kuro- 
daia, a new subgenus is herewith described.

In the British Museum (Natural History) are two male 
specimens collected off skins of Microhierax fringillarius (Dra-

included in the type material because of their poor condition 
which precludes positive identification. If these records are 
correct, they indicate that the subgenus is not restricted to a 
single host. 

This study was supported by research grant E-1722 from the

The Worker Caste of the Parasitic Ant Mono- 

morium metoecus Brown and Wilson, 

with Notes on Behavior 

By E. O. WILSON and W. L. BROWN, JR., Museum of Com- 
parative Zoology, Harvard University 

In a recent issue of ENTOMOLOGICAL NEWS we described the 
remarkable parasitic ant Monomorium metoecus from a single 
ergatogyne found in a nest of M. minimum (Buckley) at Tus- 
caloosa, Alabama (Brown and Wilson, 1957). On June 17, 
1957, the type locality was revisited with the hope of obtaining 
additional material. Fortunately, the original collection site 
had not been disturbed, and M. metoecus was successfully lo- 
cated for the second time. A most interesting discovery made 
at this time was that metoecus, unlike the great majority of 
other permanent ant parasites, possesses a functional worker 
caste. 

The new mixed colony was found at almost the identical spot, 
in open pine woods on the University of Alabama campus, 
where the type ergatogyne had been discovered seven years 
before. It was nesting in a deep vertical crevice in a partially 
buried, dead root stump at the base of a large loblolly pine 
(Pinus taeda), a situation that unfortunately rendered excava- 
tion very difficult and incomplete. The total adult population 
of the colony was roughly estimated at between one and two 
thousand; minimum workers outnumbered those of the parasite 
by about forty to one. Two dealate queens of minimum were 
recovered, but no queens or extreme ergatogynes (see below) 
of the parasite ; the latter, if they existed, were presumed lost 
during excavation. Host and parasite workers were completely 
intermingled, with no apparent tendency toward concentration 
of either species anywhere inside or outside the nest. Follow- 
ing is a brief characterization of the newly discovered metoecus 
worker caste. 

Worker: The six specimens studied (now deposited in the 
Museum of Comparative Zoology, United States National Mu- 



34 ENTOMOLOGICAL NEWS [Feb., 1958 

seum, and personal collection of A. C. Cole, Jr.) are a rather 
heterogeneous lot, and it may be that it would better approxi- 
mate their status caste-wise to consider them low-grade ergato- 
gynes. They differ from the holotype ergatogyne in their 
narrower petiolar node, as seen from the rear (width 0.24-0.28 
mm. vs. 0.35 mm. for the holotype ; three workers of M. mini- 
mum from the host nest measured 0.12-0.14 mm.). The post- 
petiole is also proportionately narrower than in the holotype. 
and the ventrolateral conules are not so well developed ; in fact, 
in several specimens the conules are not developed appreciably 
at all. The conules do not vary allometrically in this series, for 
some of the smallest specimens have them well developed, while 
the largest specimen has, to all intents and purposes, no conules 
at all. Although overall size (total length and bulk of whole 
body) is slightly to considerably less in the workers than in the 
ergatogyne, the head width measures about the same (workers, 
HW without compound eyes, 0.53-0.55 mm. vs. 0.54 mm. for 
the holotype). The alitrunk of the workers is shorter, both 
absolutely and proportionately (0.76-0.80 mm. vs. 0.88 mm.), 
and the convexity of the promesonotal and propodeal dorsal 
outlines is less marked than in the holotype. We may sum up 
by saying that the workers, if they are workers, show some dis- 
cordance in their difference from the holotype, but in general 
are intermediate between the holotype and the host workers, and 
much closer to the former. The head width of three host nest 
workers measured is 0.38-0.41 mm. ; alitrunk length (WL) 
0.52-0.61 mm. (See text-figure.) 

Prior to excavation of the nest, parasite workers were found 
in the files of minimum workers moving up and down the trunk 
of the pine tree during the day. Careful examination of these 
individuals at this time failed to reveal any peculiarities in their 
foraging behavior. Despite the fact that they are twice the 
size of the minimum workers, they followed the vertical odor 
trails on the pine trunk at about the same pace and with the 
same frequency of exploratory "side-tracking." Moreover, ap- 
proximately the same percentage were carrying small dead in- 
sects ( including psocids and aphids) gathered higher up in the

pine. Behavior in the vicinity of the nest, both before and after 
the disturbing effect of excavation, did not appear to differ 
significantly.

Following study in the field, most of the colony was removed 
and transported to Harvard University for further observation 
under laboratory conditions. Unfortunately, during the week- 
long automobile trip most of the metoecus workers died, only 
three individuals surviving to be transferred finally to an arti- 
ficial nest. Once established in the nest, the mctoccits workers 
continued to behave essentially like the minimum workers. A 
possible ethological difference that appeared at this time was the 
apparent proportionately longer periods of time spent by the 
three metoecus workers outside the nest. However, this phe- 
nomenon may have resulted in some way from the preceding 
heavy mortality of the parasite, e.g., the younger, nest-oriented 
workers may have been the first to die. Inside the nest, the 
metoecus workers were occasionally seen resting on or near the 
brood, but it could not be determined whether they were helping 
tend it. On several occasions they displayed aggressive be- 



36 ENTOMOLOGICAL NEWS [Feb., 1958 

havior, in attacking alien worker ants placed near them, in de- 
fending against probing forceps tips, etc., that was apparently 
identical to the behavior of the host workers under similar con- 
ditions. Metoecus workers also fed directly on honey supplied 
the colony. On one occasion a parasite worker was observed 
exchanging food with a minimum worker by regurgitation, but 
it could not be determined whether this individual was donating 
or receiving. All in all, the total behavior of the parasite work- 
ers did not appear to differ in any significant way from that of 
the host workers within the existing limits of observation. 

The question was now raised, whether the parasite worker is 
truly the worker caste of the previously described M. metoccus, 
as all of the morphological evidence seemed to indicate, or 
whether it represents instead merely another, aberrant worker 
caste of M. minimum. To test the latter hypothesis, the mixed 
colony, now presumed to be deprived of its parasitic reproduc- 
tive form (or forms) and at first lacking brood of any sort, was 
maintained in the laboratory under optimum trophic conditions 
for a period of five months. During this time the minimum, 
population more than doubled in size, but no new metoecus 
workers appeared. It was concluded that a metoecus repro- 
ductive form had indeed been present in the original mixed 
colony but had been lost during excavation and transfer to the 
laboratory. But of course it cannot be proved that the metoecus 
reproductive form was an ergatogyne similar to the holotype in- 
stead of a true queen or fertile worker. 

The precise relationship of the parasite to its host was now 
considered. The large size of the metoecus worker suggested 
that the parasite might be dulotic, raiding other nests of mini- 
mum to increase the number of host workers. An experiment 
was conducted in which a small colony of minimum collected at 
Amissville, Rappahannock Co., Virginia, was placed in a com- 
mon' foraging arena 23 centimeters from the mixed colony. 
Within an hour both minimum and metoecus workers from the 
mixed colony began to penetrate the nest of the Amissville colony 
and remove brood. The invaders were actively resisted by the 
Amissville workers, and only after the latter had been over-

whelmed by numbers and mostly destroyed was all of the raided 
brood removed. The raided brood, consisting solely of large 
larvae and worker pupae, was completely eaten by the mixed 
colony within twenty-four hours after it had been transported 
to the mixed-colony nest. A control experiment was then con- 
ducted in which two colonies of minimum collected at Falmouth, 
Massachusetts, were placed together in a common foraging 
arena under conditions as similar as possible to those of the 
original experiment. At the time of writing these two colonies 
have been living together for a period of three months without 
a raid developing in either direction. 

Despite the different outcomes of the original and control ex- 
periments, it is our opinion that metoecus is not a dulotic ant. 
There are several good reasons for arriving at this tentative 
conclusion. (1) The laboratory raid resulted in intense com- 
bat with complete destruction of the raided colony, and the cap- 
tured brood was quickly eaten instead of being reared, conditions 
that suggest simple predation rather than dulosis. (2) Func- 
tional host queens w r ere present in the mixed colony, not a nor- 
mal condition associated with dulosis. (3) The metoecus work- 
ers show none of the modifications, either morphological or 
ethological, commonly associated with dulosis. 

But whether the parasitism is dulotic in nature or not, it is 
clearly at a very primitive level. In fact, it is questionable whether 
on the basis of the present evidence the relationship can be prop- 
erly called parasitism at all. There is at present no sure indication 
that the metoecus workers are ethologically degenerate in any 
way, i.e., that they do not perform their "fair share" of the work 
load. The relationship is reminiscent of non-parasitic parabio- 
sis, except that in the known cases of parabiosis the participating 
colonies remain segregated in separate chambers within the nest 
and never mix their brood. It is perhaps much closer to the 
strange kind of symbiosis recently discovered as existing between 
the New Guinea dacetine ants Strumigenys loriae and Kyidris 
yaleogyna (Wilson and Brown, 1956). The two species live 
in completely mixed colonies, with Kyidris queens and workers 
forming a slight numerical minority of the adult population. 



38 ENTOMOLOGICAL NEWS [Feb., 1958 

The Kyidris workers still perform normal tasks inside and out- 
side the nest, but their behavior tends to be degenerate and inef- 
fectual, and they do not carry a "fair share" of the work. For 
example, they hunt for insect prey along with the Strumigcnys 
workers, but with very low efficiency, and they do not join in 
nest construction at all. Other cases of very primitive parasit- 
ism, or at least pre-parasitic symbiosis, may occur among species 
of the Nearctic Formica obscuriventris group, as described by 
King (1949, 1955) and King and Sallee (1951). Apparently 
various pairs of species of this group commonly form mixed 
colonies by the method of indiscriminate mutual adoption of 
newly-fertilized queens of one species by the established colony 
of another. Such mixed nests have been studied in Iowa by 
King and Sallee, and there is good evidence that they occur 
elsewhere (Brown, unpublished notes). 

The cases of Monomoriwn metoecus and Kyidris yalcoyyna 
suggest the possible first steps in one evolutionary pathway of 
permanent social parasitism. It is conceivable that parasitism 
of this sort starts when one species simply becomes resident 
with another, degenerating to the extent that it can no longer 
exist independently, but at first maintaining a normal, fully 
functional worker caste. Evolution proceeds as the worker 
caste ceases to function normally and is reduced in numbers, 
finally to be eliminated altogether.

Gall Flies (Itonididae) and Parasitic Hymenoptera 
Reared from Rosette Galls of Willow 

By W. W. JUDD, Department of Zoology, University of Western 
Ontario, London, Ontario 

On February 14, 1956, a collection of 200 "rosette" galls was 
taken from shrubs of sand-bar willow, Sali.r interior Rowlee, in 
an abandoned brickyard at the northwest corner of Taylor and 
Cheapside Streets at London, Ontario. Each gall was put in a 
separate, numbered, glass vial of dimensions 60 mm. X 15 mm., 
plugged with cotton. The vials were kept on a rack at room 
temperature in a laboratory and were examined daily for the 
presence of insects which had emerged from the galls. The in- 
sects were pinned or preserved in fluid and labelled to show the 
date of their emergence and the number of the gall from which 
each insect emerged. After December 31 all the galls were 
dissected and their contents were noted and insects remaining 
in them were removed and preserved. The flies and wasps, 
respectively, were identified by Dr. J. R. Vockeroth and Dr. O. 
Peck, Entomology Division, Department of Agriculture, Ottawa. 
All the insects are deposited in the collection of the Department 
of Zoology, University of Western Ontario, except some speci- 
mens retained in the Canadian National Collection (CNC), as 
noted in the following account. Of the 200 galls 9 yielded adult 
flies (Rhabdophaga sp.), 69 yielded parasitic wasps, 16 con- 
tained dead itonidid larvae, 51 contained dead itonidid pupae and 
55 were without contents. The numbers of adult insects reared 
and dissected from the galls are shown in table 1. 

DlPTERA 

Ttonididae 
RhabdopJiaya (rhodoides Walsh?) 

Five flies emerged from five galls between March 14 and 
April 3, including one male (March 14) and four females; and 
four females were found dead in four other galls when they 



40 ENTOMOLOGICAL NEWS [Feb., 1958 

were dissected. Five specimens are deposited in the CNC. 
Felt (1940) records that R. rhodoides causes an open rosette 
gall on willow. 

HYMENOPTERA 
Torymidae 

Toryjints sp. (near longistigma (Huber)) 

Five wasps emerged from five galls between May 14 and 
June 11 and twelve more were found in twelve dissected galls. 
Six wasps are deposited in the CNC. Wasps of the genus 
Torymus were reared by Judd (1953, 1955, 1957) from other 
kinds of galls on willow in the vicinity of London. 

Pteromalidae 
Amblymerus (salicis (Grt.) ?) 

Two wasps emerged from two galls on March 10 and April 7 
and both are deposited in the CNC. In addition, when the galls 
were dissected, two wasps of the tribe Pteromalini were found 
dead in two galls (table 1). Wasps of the genus Amblymerus 
were reared by Judd (1957) from the beaked willow gall at 
London and Muesebeck ct al. (1951) record that A. salicis is a 
parasite of an itonidid gall on willow. 

Tridymus sp. 

One wasp emerged from a gall on April 24 and thirty-four 
were found dead in thirty-four galls, with a single wasp in the 
core of each gall, when the galls were dissected. Fourteen of 
the wasps are deposited in the CNC. Judd (1953) records 
Tridymus sp. as a parasite of Rhabdophaga strobiloidcs at 
London. 

Eulophidae 
Tetrastichus sp. (near ncbraskcnsis (Grit.)) 

Four wasps emerged on March 8 through minute holes, one- 
quarter mm. in diameter, in the base of the gall which later

yielded from its core a specimen of Amblymerus (salicis?') on 
April 7 . The four wasps are deposited in the CNC. Wasps 
of the genus Tetrastichus were reared by Judd (1953, 1955) 
from other willow galls at London.

On the Genus Arhysosage Brethes from Argentina * 
(Hymen., Apoidea, Panurginae) 

By J. S. MOURE, C.M.F., 2 Department of Entomology, Univer- 
sity of Kansas, Lawrence, Kansas and Secqao de Zoologia, 
Universidade de Parana, Curitiba, Brasil 

This genus of Brethes remained unrecognized until Dr. C. D. 
Michener and I had an opportunity to examine the types in 
Buenos Aires, and found that the type species, Arhysosage john- 
soni Brethes, is the same as Camptopoewn ochraceum Friese. 
It had not previously been apparent that Arhysosage belonged 
to the Panurginae. Another genus described by the same author 
which we also found to be a panurgine is Callonychium. 

The group here called Arhysosage was well recognized and 
characterized by Timberlake who erected the genus Ruisiella 
(-- Ruisapis} for it. His placement of it in Calliopsini was not 
fortunate, however. As far as known the genus is restricted 
to Argentina.

The color variation in females of this species is very striking. 
In the large series of specimens in the Snow Entomological 
Museum, University of Kansas, is a black specimen, with only 
the following parts yellow : narrow lines along the inner and 
outer orbits, mandibular bases, an interantennal stria separate 
from preocellar spot, a very narrow band on the posterior mar-

gin of the scutellum and metanotum, and a broad band on the 
fifth tergum. There are specimens with a band also on the 
fourth tergum (bifasciata) and with interrupted bands on the 
first two terga. In other females the general background color 
of the abdomen passes to brown and in a specimen from Paso de 
los Funes, San Luiz, Argentina, the background is reddish, the 
bands reduced to small lateral spots, even on the fourth tergite, 
and interrupted on the fifth (castcllani) (I saw the type of 
castcllani in the United States National Museum). 

The males seem quite uniform, although that described as the 
male of castcllani by Cockerell makes one think of the possibility 
that males, too, are polychromatic. 

The two species described below are exceedingly similar to 
ochracea and to one another but do not exhibit the polychro- 
matism of ochracea.

Male: Coloration entirely yellow, even abdomen without 
bands; mandibles (apices fuscous), subantennal areas and ad- 
jacent parts of clypeus white ; under surface and legs very pale 
yellow; dark markings reduced to fine dark brown lines along 
notalices, scuto-scutellar suture, margins of metanotum next to 
tegulae, and the facial foveae. Wings hyaline ; tegulae, veins, 
and pterostigma yellow. 

Pilosity all pallid, very short, even on dorsum of mesonotum, 
a little longer on head and sides of thorax. 

Punctuation fine and rather dense, especially on clypeus which 
is dull. 

Width of head over twice distance from anterior margin of 
clypeus to lower margin of median ocellus (184:82) ; length of 
eye little over half of upper interorbital distance, this less than 
lower interorbital distance (75:120:165); interocellar distance 
slightly less than ocellocular (27:28) ; interantennal distance 
equal to length of scape and four times length of subantennal 
area (40:40:9), the latter distinctly broader than long (15:9) ; 



46 ENTOMOLOGICAL NEWS [Feb., 1958 

labrum almost twice as broad as long (70:40), entirely flat, 
without labral plate ("basal area of labrum"). 

Length 10 mm.; length of wing (including tegula) 6.5 mm.; 
head width 3.1 mm.; abdominal width 3.5 mm. 

The structure that distinguishes this species most easily from 
the others is the form of the clypeus of the male, which is con- 
siderably broader laterally in this species. Also, the labrum is 
relatively broader and shorter (70:30), in contrast to A. ochra- 
cea (65:40). 

Female: Entirely yellow, without abdominal bands, sutures 
mostly finely brown on head and thorax ; clypeus whitish with 
two small brown points ; brown lines of facial foveae generally 
united by an equally fine brown line behind ocelli ; ventral side 
of thorax dark brown as are coxae and trochanters, latter with 
yellow spots; sternites two to five with some brown spots. 

Width of head more than twice distance from anterior margin 
of clypeus to lower margin of median ocellus (152:83) ; eye 
length a little less than upper interorbital distance which is less 
than lower interorbital (80:92:120); interocellar distance 
slightly less than ocellocular (27:29) ; interantennal distance 
equal to length of scape and 3.4 times length of subantennal area 
(34:34:10), the latter broader than long (13:10); labrum 
without labral plate, a little elevated transversely near base, 
twice as broad as long (60:32) ; clypeus approximately five 
times as broad as long (148:30). 

Length 9.2 mm. ; length of wing (including tegula) 6.0 mm. ; 
henrl width 2.5 mm. ; abdominal width 3.0 mm.

Arhysosage germana new species 

This species is very similar to the two preceding, resembling 
more A. ochracca by the abdominal bands, but considerably 
smaller and never reaching the strong melanization common in 
that species. In the clypeal form of the male this species also 
resembles ochracea. I think it is not merely a case of allometry, 
since there is available a large number of specimens, quite uni- 
form. The three species occur sympatrically in the region of 
Catamarca. 

Male: Head and thorax yellow, abdomen of a light ferruginous 
brown with yellow bands on bases of tergites ; apices of mandi- 
bles dark and sutures of head and thorax light brown; facial 
foveae black. Wings hyaline, veins and pterostigma yellow, 
vein R rather dark. 

Pilosity white, a little more developed than in the preceding 
species. 

Punctuation a little denser than in ochracea, resembling that 
of flava. (This character most evident in clypeal region which 
in ochracea is more shining.) 

Head considerably broader than distance from clypeal margin 
to lower margin of median ocellus (144:80) ; eye shorter than 
upper interorbital distance, about half lower interorbital dis- 
tance (64:86:126); interocellar distance longer than ocellocu- 
lar (26:23) ; interantennal distance a little shorter than scape, 
three times length of subantennal area (30:32:10), the latter 
slightly broader than long (11:10); labrum without elevated 
labral plate, almost twice as broad as long (50:27) ; clypeus 
about four times as broad as long (120:29), quite narrow lat- 
erally, in this feature resembling ochracea; subapical inner 
mandibular tooth very weak, only vestigial. 

Length 7.5 mm. ; length of wing (including tegula) 5.9 mm. ; 
head width 2.5 mm. ; abdominal width 2.7 mm. 



48 ENTOMOLOGICAL NEWS [Feb., 1958 

Female: Color as in male, markings very weak on ventral 
part of thorax, less denned than in flava, black lines of facial 
foveae generally united behind the ocelli ; face generally with 
pale brown area in the form of inverted U with its base on 
ocelli and arms directed toward antennal sockets ; mesonotum 
with three more or less pronounced brown lines, one median 
and extending to anterior border, the others on each side 
shortened in front, all uniting at scuto-scutellar suture ; pro- 
podeum usually with brown T-shaped spot, cross bar of which 
is curved along base next to metanotum. 

Head distinctly broader than distance from clypeal margin 
to lower margin of median ocellus (140:86) ; eye length equal 
to upper interorbital distance but less than lower interorbital 
distance (80:81:102) ; interocellar distance slightly more than 
ocellocular (21:20); interantennal distance distinctly longer 
than length of scape and more than 2.5 times length of sub- 
antennal area (27:33:10), latter practically as long as broad 
(10:10) ; labrum without labral plate almost twice as broad as 
long (50:27) ; clypeus little over three times as broad as long 
(100:31), distinctly narrowed toward sides. 

Length 7.2 mm.; length of wing (including tegula) 5.5 mm.; 
head width 2.3 mm. ; abdominal width 2.8 mm.

Nomenclatural Changes in Trachymyrmex (Hym. : 

Formicidae, Attini) 

By NEAL A. WEBER, Swarthmore College, Swarthmore, 

Pennsylvania 

Trachymyrmex , one of the largest genera of fungus-growing 
ants, has been difficult to characterize because of its similarity 
to some Acromyrmex and Sericomyrmex and because of the di- 
versity of its species. From Acromyrmex it differs principally 
in its feeble or no polymorphism and generally greater spinosity 
and pilosity ; Sericomyrmex has a cordate head with rounded 
occipital lobes and long, abundant, silky hairs. The species of 
Trachymyrmex vary in size from 2 mm. to about 5 mm. 
and normal infraspecific variability was seldom realized when 
descriptions were first published. Examinations of the three 
chief European collections of fungus-growing ants lf 2 and field 
work and laboratory studies of living colonies have made pos- 
sible the following nomenclatural changes in the genus.

50 ENTOMOLOGICAL NEWS [Feb., 1958 

Three pins in the Forel collection are marked "Typus," one 
with three workers being labelled : "Tr. Cornetzi type, Forel, 
Sta. Martha, Colombie (Forel)." The thorax length of these 
including neck is 1.27-1.30 mm. A pin of three worker cotypes 
from the reserve collection given to me in an exchange with Dr. 
Ferriere has thorax lengths of 1.25-1.38 mm. The one type of 
the var. naranjo is somewhat spinier in places but is considered 
to be the same form. 

The annulatns type in the Santschi collection is labelled : 
"Panama, San Francisco, Bierig, 8.vi.30." It has the usual 
brown frons spot of cornctzi but so concealed by the general 
dark color as to be difficult to see. The thorax length, exclud- 
ing the neck, is 1.14 mm. or 1.2 mm. with neck. The nncijer 
type (labelled: "France Fid") in this collection is dirty and 
also very dark but faintly showing the same spot on the frons ; 
the total extended length as mounted is 3.67 mm. including 
porrect mandibles and the thorax length with neck is 1.33 mm. 

British Guiana and Surinam specimens (Weber, 1946, Rev. 
de Ent. 17 : 145 ) belong to the typical form as do the Trinidad 
representatives described as the var. bivittatus, the Barro Colo- 
rado Island, Canal Zone ants described as gatun (although with 
a feeble post-occipital tubercle lacking in the six above Forel 
cotypes), and the Rio Force (Lat. 640' N., Long. 75 10' W), 
Colombia ants called brevispinosa which are dark brown. 

This species is much more common and variable in spinosity 
and color than formerly realized. The color is frequently pale 
ferruginous. 

Trachymyrmex cucumis (Mann) comb. nov. 

1922. Myrmicocrypta cucnuiis Mann, Proc. U. S. Nat. Mus. 
61: 45." 

Two worker cotypes in the U. S. National Museum-Mann 
collection are typical small Trachymyrmex with the large post- 
petiole characteristic of the smallest species of the genus. This, 
from above, is as broad as long although being narrowed ante- 
riorly it looks longer than broad. Compared with the holotype 
of schomburgki, the habitus is similar. The thorax length is 



Ixixj ENTOMOLOGICAL NEWS 51 

the same (0.9 mm.) and has similar spinosity except that the 
lateral pronotal spines of the latter are longer. When more 
specimens of both species are available schoinburgki may be 
considered to be the same or a subspecies. The holotype of 
carib is bigger and coarser and tncuchc is more sharply rugu- 
lose on the frons, the anterior lateral pronotal tubercles are 
coarser and the postpetiole is distinctly broader than long.

Ital. 26: 221. 
1938. Trachymyrmex trifitrcatus Weber, Rev. de Ent. 9 : 199. 

New Synonymy. 

The Emery collection has a single pin labelled: "124. Para; 
n. sp. Para, Schutz ; Atta farinosa Em." which has doubtless the 
type. The thorax, including a short neck, is 1 .77 mm. long. It 
agreed very well with a paratype of trifurcatus (King Frederick 
William IV Falls, Courantyne R., Surinam, 16.vii.36, N. A. 
Weber 577) and, despite minor differences, is conspecific. 
These two ants and the holotype of trifurcatus have a peculiar 
and massive lateral gastric swelling on each side that absorbs 
the usual gastric carina posteriorly. The farinosa hairs are fine 
and simple ; some of the trifurcatus hairs are narrow-squamose 
but this is believed to be a variable character. 

Trachymyrmex opulenta (Mann) comb. nov. 

1922. Sericomyrmex opulenta Mann, Proc. U. S. Nat. Mus. 
61 : 48. 

Six worker cotypes in the U. S. National Museum-Mann 
collection are typical Trachymyrmex with the same habitus as 
u'hcclcri, which was also described as a Sericovnyrmex because 
of the unusually long and abundant silky pilosity. The well 
developed occipital tubercles, however, and the head in general 
are not those of Sericomyrmex as now considered (and as char- 
acterized by Mayr originally). The opulenta cotypes have 
shorter occipital tubercles and higher basal carinae on the epino- 
tum anteriorly than wheclcri cotypes.

Trachymyrmex saussurei Forel 

1884. Atta tardigrada st. saussurei Forel, Bull. Soc. Vaud. Sc. 
Nat. 20: 361. 

The Forel collection now was found to have only Sericoin\r- 
mex saussurei Emery (and under Sericomyrmex) , an entirely 
different ant, but the Santschi collection has one specimen under 
Trachymyrmex labelled: "A. acrom. Saussurei For. (Per- 
gande) ; Samlung Dr. F. Santschi Kairouan." It is in the space 
labelled Trachymyrmex saussurei Forel. 

The extended length of the ant (a worker) is 4.30 mm., the 
thorax 1.90 mm. It is bigger and coarser than septentrionalis 
but with the same general arrangement of spines and head con- 
tours. The postpetiolar node from above is 0.4 mm. long X 0.46 
mm. wide. A pin of three workers from the duplicate Forel 
collection given to me by Dr. Ferriere in exchange appears to be 
type material. It bears the labels : "41 ; Mexiq. Orizaba ; A. 
Saussurei, Forel ; en de Saussure." A pin of one worker 
given to me by W. M. Wheeler in the 1930's bears the label 
"Tepic, Mexico" and the label written by his secretary at the 
time "Cyphomyrmex (Trachymyrmex) saussurei Forel." The 
three workers may be type material. In the Biologia Centrali- 
Americana Tepic and Orizaba are the localities listed for the 
species. 

This species may be close to the parental stock from which 
the far-ranging septentrionalis was derived and the ants may 
have spread along the northern Gulf of Mexico coast to and 
along the Atlantic coast. The resemblance between the two 
species is so close that one could still be considered a subspecies 
of the other. Since septentrionalis was described earlier, this 
would be the species name although perhaps inappropriate from 
the point of view of origin.

Comp. Zool. 104: 323. 

In his original description, McCook called attention to the 
variability of the worker caste from 3 to 4 mm., referring to 
them as "workers major and minor." As Creighton has shown 
(and as Wheeler intimated for irrorata and crystallina}, verte- 
brata, irrorata and crystallina are variants of no taxonomic sig- 
nificance and the present author believes that obscurior and 
seminole have the same value. Numerous colonies of New 
Jersey and Florida origins kept in the laboratory have shown 
the variation in size that McCook was the first to realize. 
Color varies greatly and appears of no consequence in this spe- 
cies. Biological studies of these two populations (Weber, 1956, 
Ecology 37: 150-161, 197-199) have proven their fundamental 
similarity. 

The geographical range of this species, while considerable, is 
not unusual for a fungus-grower and the ecology appears quite 
uniform, with temperature the chief variant.

54 ENTOMOLOGICAL NEWS [Feb., 1958 

(Matto Grosso). The upper ant has a thorax length of 1.77 
mm., the lower ant 1.57 mm. They are no darker than some 
Panama and Colombian specimens and in other characters 
appear to be within the normal range of infraspecific variability. 
The Forel collection contains a large series of the types of 
marthae and a pin of three workers was secured by exchange 
with Dr. Ferriere. It bears the label : Tr. Urichi Forel ; r. 
Marthae Forel; Sta. Martha, Colombie (Forel). They are a 
dark brown but otherwise like urichi, which has been collected 
numerous times by the author in the type locality, Trinidad (see 
Rev. de Ent. 1945, 16: 44-54). The subspecies pananicnsis 
was based largely on color and these ants have since been found 
to be common on the Pacific slopes of Panama. While often of 
the color described by Wheeler, specimens from the same locali- 
ties, but taken in March, 1957, during the height of an unusu- 
ally severe dry season, were as dark as those named marthae by 
Forel. The subspecies radicis was based on small specimens, 
probably of a young colony. The species also occurs in Vene- 
zuela. Throughout its range it is an ant of the savannah or 
grass-woodland rather than of closed forests.

Ent. 7 : 398. New Synonymy. 

In pilosity and high mesonotal spines these ants resemble 
Scriomyrmex. However, the head is typical Trachymyrmex. 
They have the same habitus as opulcnta but six cotypes in the 
U. S. National Museum have distinctly shorter occipital spines 
and higher basal carinae on the epinotum anteriorly. The type 
series of pakcelai consistently show lower and more rounded 
occipital spines, lower mesonotal spines and much more marked 
tubercles on the declivous surface of the mesonotum. These 
are believed now to fall within the normal infraspecific range of 
variability. Additional collecting and study may show wheel cri 
to be no more than a subspecies of opulenta. 



Ixixj ENTOMOLOGICAL NEWS 55 

Specimens taken by the author at Rio Force (Lat. 640' N., 
Long. 75 10' W.), Colombia in 1938 are of this species. Males 
and females came to lights about 3-4 A.M., August 1 and a 
nest containing males was excavated July 21. The workers are 
dark brown. This species does not appear to have been taken 
in Colombia by Forel and is not his gaigei.

Additional collecting and study since 1938 in the type locality, 
Barro Colorado Island, Canal Zone, show that the differences 
noted in the two species cannot be sustained and that they are 
best considered to be the same species, zeteki having page pri- 
ority. A colony kept for over two years in the laboratory shows 
a variation in worker morphology that was unknown in 1940. 
A conspicuous feature is the spatulate pilosity but this is of 
variable extent.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Acshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hespcraeschna, Rhio- 
naeschna, Schisuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other ; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

The Plesiallotype Female of Oligoclada umbricola 

Borror, 1931 

By EDWARD J. KORMONDY, Department of Zoology, 

Oberlin College 

In the preparation of type specimens of Odonata in the C. H. 
Kennedy Collection acquired by the University of Michigan 
Museum of Zoology, a female labelled "Oligoclada umbricola 
Borror, Allotype" by Kennedy, was found. The specimen, 
which Kennedy undoubtedly intended to describe, was in poor 
condition with the hind wings free, and the abdomen broken 
into several pieces. Two other females were found in the col- 
lection; one had been determined as O. umbricola by Borror; 
the other was in an envelope containing a male umbricola f not 
seen by Borror but presumably seen by Kennedy. The three 
females, along with eight males, were collected for Kennedy by 
William Clarke-Maclntyre ; they are from Province de los Rios, 
Ecuador, and were collected March 4-April 12, 1938. These 
records extend the known range of the species southward from 
Colombia and Venezuela (Borror, 1931). 

The female umbricola is distinguished, as is the male, by the 
structure of the occiput. This differs from the male only in the 
presence of two posterio-medial brownish yellow elongate spots. 
Additional differences from the male are described below. 

The plesiallotype, labelled "Ecuador : Province de los Rios, 
Playas, April 12, 1938, W. Clarke-Maclntyre," is deposited in 
the type collection of the University of Michigan Museum of 
Zoology.

Some Observations upon the Fauna of the Winter 
Nests of Euproctis chrysorrhoea (Lepidoptera) 

By JERZY J. LIPA, Laboratory of Agricultural Entomology, 
Institute of Plant Protection, Pulawy, Poland 

The caterpillars of E. chrysorrhoea construct nests in which 
they hibernate. I collected these nests during the winter and 
summer, and have also located nests in greenhouses. From the 
nests collected during the winter emerged the caterpillars of 
E. chrysorrhoea, and also larvae and adults of other species. 
However, from the nests collected during the summer (when 
the caterpillars had already left the nests) there emerged only 
the larvae and adults of other species. 

Most interesting was the frequent occurrence of mixed winter 
nests in which there hibernated the caterpillars of both E. chry- 
sorrhoea and Aporia cratacgi. 

During the winter the following species were observed in the 
nests : 

LEPIDOPTERA: The caterpillars of A. cratacgi and other species. 
HEMIPTERA : Larvae of Lecanium corni and Lccaninm sp. 
ACARINA: Tctranychus urticac and other Tetranychidae. 
HYMENOPTERA PARASITICA : Eupteromalus micropterus, E. nidu- 

lans, Monodontomerus acrcus, and other species. 
ARANEIDA : Araneus ciiciirbitimis, Philodromus sp., Clnbiona 

sp., Thcridimn notatum. 
APTERYGOTA : Various species. 

During the summer, I have observed the following : 

HEMIPTERA : Lygus pabulinus, Plcsiocoris rngicollis, Klcido- 

cervs rcscdac, Anthocoris ncnwrmn, Anna ciistos, and others. 

COLEOPTERA : Sn licoccmclla 24-punctata, Coccinclla 7-punctata, 

C. bipitnctata, Phalacrus fiiucntarhts, and others. 
ACARINA : various species. 

Discussion. The winter nests of E. chrysorrhoea, during both 
winter and summer, are the hiding places of the larvae and 
adults of other species. Some of these are predators or para- 
sites, but since the majority are pests, the removal of the nests 
from trees is desirable.

Two New Species in the Genus Pompilinus 

(Hymenoptera: Psammocharidae) with 

Photomicrographs of the Genitalia and 

Subgenital Plate of the Male 

By R. R. DREISBACH, Midland, Michigan 

Pompilinus clavipes n. sp. 

Holotype male : Color completely black with the faintest very 
short, white line on the upper posterior orbits, and the tips of 
the mandibles reddish ; only very scattered short hair over the 
front, vertex, and the clypeus, with longer hair on the upper 
posterior orbits, and under parts of the head ; almost the whole 
body sericous, the front, clypeus, almost all the thorax, and the 
legs mostly covered with sericous hair ; very shiny patch of a 
little longer hair on the posterior orbits ; when seen from the 
side the front is visible above the eyes, the vertex is very slightly 
raised, and the nearer ocellus is completely visible ; the clypeus 
is almost flat but slightly convex in middle ; when seen from 
the front, a small rectangular plateau on the vertex carries the 
ocelli ; the antennae are short and the joints are more than twice 
as long as wide with a silvery sheen when viewed in reflected 
light; the apical joint is blunt; the first and fourth joints are 
longer than the third ; the ratio of the first four and last two 
joints are as 15:6:12:15:10:12; the pronotum rises in a smooth 
curve and is almost flat on top ; the propodeum has a slight slope 
to the rear and the posterior and dorsal parts are connected by 
a smooth curve ; propodeum is without hair but covered with 
appressed, beautiful silvery pubescence ; the wings are brownish, 
hyaline, with the space beyond the cells considerably darker ; 
the ratios of the joints of the posterior legs starting with the 
femur are as 83:81:63:27:22:15:20; the posterior tibia with 
its longest spur two thirds as long as its metatarsal joint; the 
distance between the lateral ocelli is equal to the distance from 
them to the eye ; the interocular width at the vertex is slightly 
more than at the clypeus ; the clypeus is one third times as 
long as its width; head 1.14 times as wide as long; the length

Holotypc male : 8/8/1952, R. R. Dreisbach, CONLON, Texas. 
(MCZ). 

Genitalia of this species are very distinctive by virtue of the 
much broadened parameres, expanded very sharply about the 
basal third, and by the very long rather heavy hairs arising from 
the inner edge and the long slightly thinner hairs on outer edge ; 
the subgenital plate is unique in shape, and is suddenly reduced 
about the apical third ; heavily haired about this width to near 
the base and with semi-translucent sides on basal two-thirds.

trace of a white streak on upper posterior orbits, and apices of 
the mandibles reddish; thinly placed hair on the vertex, under 
the head and a few very short hairs on the pronotum, practically 
none on the propodeum ; when seen in facial aspect, the front 
just above the antennae is slightly raised sloping to the vertex, 
clypeus slightly arched in front of apex, slightly raised above the 
mouth ; head slightly wider than long ; antennae very slender

Studies of the Byron Bog in Southwestern Ontario. 

VI. Seasonal Distribution of the Wood Gnat, 

Silvicola marginata (Say) (Diptera: 

Silvicolidae) 

By W. W. JUDD, Department of Zoology, University of Western 

Ontario, London, Ontario 



In the description of the Byron Bog (Judd, 1957) it was 
pointed out that one method of collecting insects in the bog was 
the use of a baited trap. The position of the trap in the bog is 
shown by Judd (1957) and its mode of operation is also de- 
scribed (Judd, 1956). The trap was in operation during 1956 
from May 15 to November 15 and over that period flies and 
other insects were removed from the trap each day and the num- 
bers of the several species trapped were recorded. Among the 
insects so callected was the wood gnat, Silvicola marginata 
(Say). The insect was identified by Dr. A. Stone, Division of 
Insects, United States National Museum, who retained five 
specimens for the U.S.N.M. Other specimens are deposited in 
the collection of the Department of Zoology, University of 
Western Ontario. 

The first gnat was trapped on June 21 and during the whole 
period of operation of the trap 14,855 gnats were trapped, the 
last being caught on November 1. Their seasonal distribution

is shown in fig. 1. The greatest number caught on one day, 
731, appeared in the trap on August 9. Between July 1 and 
August 8 the daily catch was sorted according to sex and yielded 
1,963 eft? (51%) and 1.883$$ (49%).

Seasonal distribution of Sili'icola inari/inata ( Say ) 



'NOV. 



Edwards (1923) points out that Sili'icola (Anisopus) uiaryi- 
nata (Say) is distinct from the European putictatits, for which 
several records of distribution in North America occur in the 
literature (e.g. Leonard, 1926). He based his decision on ex- 
amination of specimens of inarf/hwta collected at Montreal, 
Quebec. The presence of the large population of 5\ marginata 
in the Byron Bog is in accord with the known habits of the gnats 
of this family as recorded by authors (e.g. Curran, 1923), for 
they occur near the edges of woods and in the vicinity of swamps 
and breed in wet or moist decaying organic matter.

80 ENTOMOLOGICAL NEWS [Mar., 1958 

Review 

ANNOTATED CATALOGUE OF AFRICAN GRASSHOPPERS. Com- 
piled by H. B. Johnston, with a preface by B. P. Uvarov. xxii 
+ 833 pp. Cambridge, England (Cambridge University Press, 
published for the Anti-Locust Research Centre). 1956. Price 
5, 5 shillings (in the United States $18.50). 

The preface of this timely and most important reference work, 
for both systematic and economic workers concerned with the 
acridoid fauna of Africa, was prepared by Dr. Uvarov, Director 
of the Anti-Locust Research Centre. His resume of various 
aspects of locust problems in Africa should be read by all con- 
cerned with these matters in other areas. As there explained 
it was found essential for a sound approach to an understanding 
of African grasshopper problems to have a comprehensive syste- 
matic catalogue as a basis for work. The last world catalogue 
of the Acridoidea, published in 1910 by Kirby, was faulty in 
numerous respects ; while the intervening years have seen an 
enormous increase in our knowledge of these insects, in Africa 
as elsewhere. 

At the request of the Anti-Locust Research Centre, Dr. 
Johnston, who for years had been closely associated with locust 
problems in the Sudan and elsewhere, and whose knowledge of 
the fauna is comprehensive, devoted some years to the comple- 
tion of the present catalogue, which brings together our knowl- 
edge of the systematics of African grasshoppers as of the end 
of the year 1953. All the families of the Acridoidea found in 
Africa, except the Tetrigidae, are included. 

As the introduction states, "Nothing new in synonymy, tax- 
onomy or distribution has been introduced, and though the 
arrangement of the material may present certain novel features, 
the work is in no sense a revision but merely a reference book." 
It would be a wonderful thing if those preparing similar cata- 
logues could be persuaded to allow their presentations to rest 
solely on previously published analytic work, and to restrain 
tendencies to rearrange things without adequate presentation of 
reasons or demonstrable evidence. Unlike the treatment found 



Ixix] ENTOMOLOGICAL NEWS 81 

in numerous catalogues, the compiler has added a bibliography 
covering thirty-seven pages, which arrangement has materially 
reduced the bulk of the work by permitting the use of reduced 
reference citations. Aside from its immediate usefulness to one 
consulting the catalogue, this bibliography will be of the greatest 
value to present and future students of African grasshoppers. 

The coverage of the catalogue embraces the continent of Africa 
and "the adjacent islands of the Atlantic and the Indian Ocean." 
The species whose distribution ranges extend beyond Africa 
required special treatment, and for these the more important 
non-African references and some of their synonymy are also 
included. In the case of the swarming locusts, on account of the 
great bulk of the economic and correlated literature bearing on 
them, it has been found possible to quote only the purely taxo- 
nomic and faunistic references for the five major African species 
of this category. 

Since limitation of space has compelled the use of as concise 
an arrangement as possible consistent with clarity and ease of 
reference, full journal references are omitted from the systematic 
arrangement, but the papers can readily be located in the bibli- 
ography to which references are given by author, year and page. 
A system of symbols has been utilized to indicate the location of 
illustrations, misdeterminations, and preoccupied and substituted 
names. Genera have been arranged into subfamilies, tribes and 
groups according to usage as expressed in print up to the end 
of 1953. The compiler has noted "it is necessary to state here 
that no taxonomic or nomenclatorial value is attached to any 
names above the generic rank." In view of the fact that there 
are among some students of the African grasshopper fauna 
marked differences of opinion as to the worth, relative value 
and scope of numerous higher entities, Dr. Johnston is to be 
congratulated on this policy. 

Immediately after the name of the genus, that of its type spe- 
cies is given, with an indication by a suitable term as to how, 
when, and by whom this was designated. The species in each 
genus are arranged alphabetically, subspecies are given under 
the nominate species with their treatment in general the same 



82 ENTOMOLOGICAL NEWS [Mar., 1958 

as full species. References are arranged chronologically under 
species. Type localities are those "given by the original author 
with such supplementary information as may be given by a 
later reviser." The location of the type has been given wherever 
possible, "according to direct indication by the author, by infer- 
ence from the original text, or from later references in litera- 
ture," the owning institution being indicated by its abbreviated 
name, a listing of which is given in the introduction. Some few 
institutions cited in the body of the work, however, are not given 
in the introductory listing. 

A very useful set of summarized annotations has been used 
to broaden the value of the catalogue as a reference work. 
These, given after each species, indicate which of the references 
cited presents a description, a figure, is in a key to species, or 
discusses the morphology, nymphal stages, ecology, bionomics, 
economic importance and distribution. Under the latter the 
references, which are individually numbered under each species, 
are grouped under North Africa, West Africa, East Africa, 
Central Africa, South Africa, Indian Ocean Islands, Atlantic 
Islands, and extra-African distribution. 

To those who have prepared catalogues, even if only for per- 
sonal use and not for publication, the amount of labor involved 
is well known and appreciated, and the meticulous way in which 
Dr. Johnston has brought together the exceedingly extensive 
and widely scattered information, which is summarized in this 
work, merits all possible praise. He, like all true bibliographers, 
has taken nothing second-hand, and citation errors of the past, 
which in some cases have been handed down through the years, 
have been corrected. The impersonal way in which the com- 
piler has handled the literature gives to his work an exceptional 
character. The catalogue is fully indexed, and is as a whole a 
splendid piece of bookmaking. In its taxonomic, phylogenetic, 
and related aspects it is an excellent reference work, clearly a 
model for comprehensiveness, cohesiveness and ease of handling. 
To Dr. Johnston, to the Anti-Locust Research Centre, and to 
Dr. Uvarov, who inspired it, go the thanks of all who work to 
any degree with African acridoids. To the entomological fra- 



Ixix] ENTOMOLOGICAL NEWS 83 

ternity there has been given a model for similar works on other 
areas. Also we are promised supplements which will keep the 
general coverage of the subject relatively up to date.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schisuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schisuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other ; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

A Key to the Superfamilies and Principal Families 
of the Oribatei (Sarcoptiformes: Acarina) 

By TYLER A. WOOLLEY,* Department of Zoology, Colorado 

State University, Fort Collins, Colorado, and EDWARD W. 

BAKER, Entomology Research Division, Agr. Res. 

Serv, U. S. D. A. 

Although several keys to the oribatids are available, none is 
completely adequate. Cited in chronological order, these keys 
are in the publications of Sellnick (1928), Willmann (1931), 
and Baker and Wharton (1952). Grandjean (1953) and Dubi- 
nin (1954) wrote papers on classification and presented the 
oribatids at the family and superfamily level, but neither had a 
key. This paper is an attempt to direct and help organize the 
thinking of acarologists and students at the higher taxonomic 
levels, and to consolidate the differentiating characters of the 
common families in a simple key. 

Some of the taxonomic designations indicated in this paper 
differ with respect to existing arrangements in the literature. 
The writers feel, however, that the simplified system included 
here will facilitate the identification of the oribatids to family 
and that minor differences in the systematic designations at this 
level will be resolved as the taxonomy of the whole group 
becomes clarified. 

The following key to the higher categories and principal fami- 
lies of oribatid mites is a nature sequel to the paper A PRE- 
LIMINARY ACCOUNT OF THE PHYLOGENY OF THE ORIBATEI, pre- 
sented by the senior author at the Tenth International Congress

Science Foundation.

of Entomology at Montreal, Canada, in the summer of 1956. 
Such a key was intended as a corporate part of that paper, which 
is in press, but could not be included in the publication because 
of limited space. The present key follows the systematic ar- 
rangement of this article in most instances, although one or two 
obvious alterations have been made. 

The writers have included some generalized drawings for ori- 
entation purposes, but have illustrated specific points in the key 
by citing figures in the literature. Three sources of figures are 
indicated by the letters of the authors' names, viz., Baker and 
Wharton (1952), Sellnick (1928), and Willmann (1931). The 
figure numbers in these works are cited following the initial 
letter of the author's surname, e.g., Baker and Wharton, Fig. 
372, is rendered B&W 372 ; Willmann, Fig. 27, becomes W 27 ; 
Sellnick, Figs. 37-40, is indicated as S 37-40. 

In spite of certain exceptions, the key should provide the 
means to identify the more common oribatids to superfamily 
and family. In one or two cases a minor group, which may be 
considered a separate family by some other authors but which 
bears general resemblance to a larger family, is incorporated in 
the larger family. In other cases, families, although lacking 
specific key characters, are placed in a particular superfamily 
because of general resemblance. Indications of both of these 
situations are handled by footnotes.

On a Collection of Centipedes from Wisconsin 

(Chilopoda) 

By R. E. CRABILL, JR., Smithsonian Institution, 
Washington, D. C. 

The following records constitute one of the two known faunal 
reports on the significant and polyglot chilopod population of 
Wisconsin. 1 It has been made possible through the energy and 
generosity of Dr. and Mrs. Herbert W. Levi of the Museum of 
Comparative Zoology at Harvard. I should like to express my 
gratitude to them for the sizable collection of carefully preserved 
specimens of which most of the present localities are repre- 
sentative. 

Though this report is admittedly fragmentary and introduc- 
tory, in my estimation it still suggests at least that the state sup- 
ports a rather versatile fauna, more versatile than the mid- 
western states' immediately to the south. This is apparent from 
the coexistence in Wisconsin of typical Austral and Transitional 
species, the latter evidently more prevalent than the former. 
For example we find such cold-adapted forms as Escaryus urbi- 
cus, Lithobiiis jorficatus, and Taiyubius harrielae but also such 
Austral species as Arenophilus bipuncticeps and Sosibius sp., 
the advance of the latter no doubt being encouraged by the same 
edaphic and particularly climatic conditions that support the ex- 
tension of the midwestern prairie into the extreme southeastern 
counties. 

In the ensuing discussion collection stations are identified by a 
formula following each species name. A capital letter refers to 
a county, and the associated number to a locality within that 
county. The list of counties below is arranged as they occur 
from north to south : an asterisk indicates a Levi collection, the 
absence of one that the record is drawn, instead, from the 
literature. 

1 An earlier report is D. C. Matthews' unpublished doctorate thesis, 
"The Chilopoda of Wisconsin," The University of Wisconsin, Thesis, 
1935.

GEOPHILOMORPHA 

Schcndyla ueiuorensis (C. L. Koch). [T-l*]. Two males, 
each with 41 pairs of legs, were captured in leaf litter. This 
tiny schendylid, which is quite common in western Europe, is 
now known to be widespread east of the Mississippi River where 
it prefers the colder, wetter winters of the more northern states. 
Both this and the next species show a remarkable tolerance to 
cold ; I have found both in the vicinity of Ithaca, New York un- 
der snow-covered stones during brief February thaws. 

Escaryus urbicus (Meinert). [O-l*]. A single male with 41 
pairs of legs was found. To date this species has been recorded 
from a few localities in Massachusetts, New York, and montane 
Virginia, but west of the Appalachians it had been known only 
from Ohio and Minnesota. Such records, however fragmen- 
tary, suggest a distribution in the colder or mountainous parts 
of the northeastern North American continent.

Arcnophilus bipuncticcps (H. C. Wood). [T-l*. U-l|. A 
male with 59 and a female with 67 pairs of legs were collected 
at Madison. The presence of what is probably our most wide- 
spread Austral geophilomorph in southern Wisconsin points 
to an extension of elements of the midwestern fauna northward 
into this region. In the extreme east it extends up the Atlantic 
seaboard through Long Island even as far as maritime Mas- 
sachusetts, though its presence inland has never been demon- 
strated. Perhaps the shorter growing season and colder winters 
preclude its invading New York north of New York City and 
interior and upper New England. The peculiar tendency of 
this animal, when disturbed, often to retreat backwards at some 
speed has proved a good field character : I have detected this 
remarkable behavior in no other eastern North American 
geophilomorph. 

Geophilus vittatus (Raf.) [olun G. rnbcns Say]. [C-l, J-l*, 
L-l*, O2*-3*, P-l*, R-l*, S-l*, T-l*, V-l j . Numerous speci- 
mens were collected throughout the southern two-thirds of the 
state. More abundant and more widely-dispersed than any 
other centipede in Wisconsin, vittatus similarly is probably the 
most ubiquitous and commonly-encountered chilopod in North 
America east of the Rocky Mountains. It has been recorded 
from New England to Nebraska and Arizona, though in the ex- 
treme south it appears to prefer the higher, hence more tem- 
perate, elevations. Afield I have found it typically under tree 
bark, where the females may be found brooding their eggs and 
young in the spring and early summer, but it seems distinctly 
less common under stones and debris on the ground. 

Strigauiia chionophila H. C. Wood [sensu lat.}. [A-l, F-l*, 
K-l*, O-l*-2*-4*-5, P-l*, Q-2*. R-l*, S-l*-3*, T-l*]. Re- 
search nearing completion at the present time shows that at least 
three sibling species have been referred to the Wood name in 
the past ; consequently to keep confusion at a minimum pending 
publication of these studies, I am assigning all of the Wisconsin 
specimens provisionally to chionophila. Members of at least 
two species of this complex were found to be quite prevalent in 
the state, each locality yielding a number of specimens from leaf 
litter. 



96 ENTOMOLOGICAL NEWS [April, 1958 

Strigamia bothriopa H. C. Wood [sensu stricto]. [H-l*, 
O-l*-2*-3*, P-l*, Q-l*, R-l*, T-l*-2*]. Until recently 2 this 
striking crimson centipede was considered a junior synonym of 
Linotaenia (= Strigamia) julva Sager, and since bothriopa is 
by far the commoner and more widespread of the two, existing 
statements of distribution are highly misleading. Wood's form, 
though present in parts of the south and midwest, is particularly 
abundant in the north and at higher elevations throughout its 
range. On the basis of Levi's collections, it appears to be al- 
most as common as Geophilns vittatus (q.v.) in Wisconsin. 
Unlike this species, bothriopa seems to prefer living close to the 
ground. In New York State I have found it almost always un- 
der stones and debris, and quite often in leaf litter. 

Taiyuna opita Chamberlin. [G-l*, N-l*, O-l*-4*, R-l*, 
S-3*, T-l*]. Heretofore this tiny chilophiline was known only 
from the type localities "Posers and Kimball's" [sic] in Michi- 
gan. Consequently it is of some interest to find it fairly wide- 
spread and evidently common in leaf litter in a neighboring north 
midwestern state. On the basis of our information to date, it 
is apparently absent to the south and east of Michigan, though 
additional records should be anticipated at least in Iowa and 
Minnesota and possibly in adjacent Canada. The known distri- 
bution of the genus is interesting, for apart from the midwestern 
opita, its species are common only to Arizona, California, and 
British Columbia. All of the Wisconsin specimens are females, 
each with 41 pairs of legs. 

SCOLOPENDROMORPHA 

Scolopocryptops rubiginosa L. Koch [olim Otocryptops rnln- 
ginosus}. [O-l*, R-l*]. Only two specimens were taken. 
The species is known from eastern Asia, from Alaska, and from 
most of the more northern midwestern states of this country 
(i.e., from Ohio through Nebraska and northern Missouri 
through Minnesota), thus suggesting a great arc from Asia 
across the Bering Straits and down into middle North America. 
So far as is known, it is absent west of Nebraska, in the south,

and in the states east of Ohio. It may be significant that the 
closely-related sexspinosa (Say) is extremely common in the 
latter areas east of the Rocky Mountains. 

LlTHOBIOMORPHA 

Lamyctes fulvicornis (Meinert). [A-l, D-l, E-l, T-l*, 
U-2]. A single female was captured in Madison. This cos- 
mopolitan henicopid has been cited often for its striking ability 
to acclimate itself to a variety of environments. It has been re- 
corded from most of the more northern United States east of 
the Rocky Mountains, from Europe where it is evidently wide- 
spread, and from such unlikely places as the Arctic Circle in 
Canada, and New Zealand. In the eastern United States it 
seems almost limited to sites in or near our cities and towns, which 
is in accord with the virtual certainty that it has been introduced 
repeatedly into this country from Europe and elsewhere. I have 
found this and other henicopids quite commonly upon fairly 
moist, sandy soils, especially close to waterways in Transitional 
eastern North America. 

Bothropolys multidentatus (Newport). [Q-3*]. The pres- 
ence of but a single specimen of this extremely familiar and typi- 
cally dendrophilous northeastern ethopolyine in the Wisconsin 
collection is not so odd when one recalls that the Levi material 
was taken largely from leaf litter. This handsome species is 
usually readily encountered throughout its range, which extends 
from Maine west to Missouri and south to higher elevations in 
the Gulf states. 

Lithobius forficatns (Linne). [G-l*, J-l*, M-l*, T-l* ; pub- 
lished accounts stress its abundance throughout the state]. 
Numerous collections, representing nearly all stages of both 
sexes, were made in the localities given above. A widespread 
European form, forficalits has undoubtedly been introduced into 
the United States repeatedly, probably since colonial times, so 
that today its presence in or near most areas of human traffic 
cannot be doubted. It is interesting that the species is rarely 
found at any great distance from places of human activity, even 
when such areas are known to be capable of supporting a dense 



98 ENTOMOLOGICAL NEWS [April, 1958 

and varied lithobiid fauna. Consequently in our northern woods 
it is replaced by the dominant Bothropolvs uiitltidcntatus, and, 
as Chamberlin pointed out long ago, in the south of the United 
States it is replaced by the several species of NeolithoHus which, 
despite a superficial similarity of general habitus, are not very 
closely related to the European form. 

Nadabiiis liohingcri (Bollman). [H-l*, N-l*-2*, O-l*-4*- 
5*, R-l*, S-l*-2*] . Each of these localities yielded a few speci- 
mens assignable to hohingcri. This form is clearly more closely 
allied to iozvcnsis than to anything else, the two differing in one 
or two rather unconvincing features. There is the good likeli- 
hood that future research will show hohingcri to be a variant of 
iowensis. Bollman's species has been reported from south- 
eastern Minnesota, from Wisconsin, and from Indiana. 

Nadabiiis iozvcnsis (Meinert). [B-l, D-l, F-l*, G-l*. 1-1*, 
O-3*, P-l*, R-l*, S-l*, T-l*, U-2]. Numerous specimens, 
representing both sexes and all stages of post-anamorphic de- 
velopment, were collected. The species, a hallmark of the mid- 
western lithobiid fauna, ranges from Idaho [ ?] east to Ohio and 
south to Tennessee. It seems completely replaced in the Ap- 
palachians by aristcits and pulliis, and in New York and New 
England by oristciis alone. 

Sozibins sp. [T-l*]. The poor condition of the single male 
does not permit further identification. 

Taiyubius harrielac (Chamberlin). [T-l*]. The Levis col- 
lected one male at Madison. Originally described from Colo- 
rado, this distinctive form now has been reported from Nevada, 
from Wisconsin, from Ithaca, New York, and from eastern Mas- 
sachusetts a most remarkable distribution for a North Ameri- 
can lithobiid. Perhaps the poverty of records is due to our 
failure to detect the presence of the species, which may be de- 
pendent upon narrowly restrictive environmental conditions. 
For instance, at Ithaca I have never failed to find specimens but 
only on non-sandy soil in a very cool, damp ravine through 
which Cascadilla Creek flows. Despite intensive searching, no 
other local site yielded a single specimen. On the basis of its 



Ixix] ENTOMOLOGICAL NEWS 99 

distribution it seems safe to predict its eventual discovery 
throughout the colder northeastern states. 

Tidabius sp. [T-1*J. One specimen was captured, but its 
condition makes specific identification impossible. It is prob- 
ably either tiviiis, which Chamberlin reported from Janesville, 
or opiphilus, known only from the type locality at Beloit. 

SCUTIGEROMORPHA 

Sciitigera colcoptrata (Linne) [olini Scutigera forceps 
(Raf.)]. [N-3*, T-l*]. Ten specimens were collected. This 
common domiciliary species, which has been introduced from 
Europe, should be expected through the United States in, or oc- 
casionally near, human habitations.

Synonymic Note on Ants of the Genus Paracryp- 
tocerus Emery (Hymenoptera: Formicidae) 

By WALTER W. KEMPF, O.F.M., Sao Paulo, Brazil 

Frederick Smith, in 1867, described four new species of 
Cryptocerus (now : Paracryptocerus) from specimens in the 
collection of W. Wilson Saunders. Through the kindness of 
Mr. Ernest Taylor of the Hope Department of Entomology, 
Oxford University, I received on loan the types of the aforesaid 
species and was thus enabled to establish two cases of new 
synonymy and to confirm another case already proposed by 
Emery (1922, Gen. Ins. fasc. 174, p. 311). 

Paracryptocerus conspersus (F. Smith) 

1867. Cryptocerus conspersus F. Smith, Trans. Ent. Soc.

1911. Cryptocerus dcnticulatus var. varicgata Forel, Sitz.-ber. 

Bayer. Akad. Wiss., p. 262. 

The holotype (unique) of conspersus, a worker from the 
Amazon, has all the distinguishing features of dcnticulatus 
which, as shown in a study to be published elsewhere, is noth- 
ing but the worker of targionii, based on a soldier. There are, 
however, a few trivial differences which deserve mentioning. 



Ixix] ENTOMOLOGICAL NEWS 109 

Measurements of holotype : Total length 3.9 mm. ; max. length 
of head 1.00 mm.; max. width of head in front of the eyes 1.03 
mm.; interocular width 1.00 mm.; Weber's length of thorax 
0.97 mm. ; max. width of thorax 0.78 mm. 

Lower face of head finely punctate, lacking traces of longi- 
tudinal rugosities. Thorax rather narrow. Lateral border of 
pronotum (excluding the scapular corner) tridentate, the first 
two teeth acute, completely separate, the third tooth subrec- 
tangular. Lateral tooth of mesonotum acute. Lateral border 
of epinotum with 5 teeth: 1st short and subacute; 2nd stronger, 
acute ; 3rd or supplementary fine and needle-like ; 4th as 2nd ; 
5th at the bottom of the declivous face, rather blunt. Dorsal 
denticles on body of petiole obsolete. Dorsum of postpetiole not 
forming in profile a right angle, but only a moderate and con- 
tinuous curvature, lacking posteriorly a median, faintly circum- 
scribed, triangular area. First gastric tergite with a median, 
black, lozenge-shaped area, surrounded by a narrow, brown 
or ferruginous, stripe, cutting off the black antero-lateral lobes, 
the borders of which bear a narrow hyaline crest. For the rest, 
it is like the worker of targionii, including the row of sparse 
standing hair along the posterior border of the first gastric 
tergite. 

The small size (from incipient colony?) of this individual 
seems to account for most of the previously mentioned differ- 
ences, which do not allow for a specific distinction between 
conspersus and targionii. The type specimen of conspersus fits 
surprisingly well the description of Forel's variety variegata, 
founded upon specimens collected by Bates on the Amazon 
river. It is quite possible that the conspersus holotype was 
likewise taken by Bates, and even that both conspersus and 
variegata came from the same nest series. At any rate, the 
latter is a strict synonym of conspersus. The same applies to 
targionii (-- denticulatus} , unless the soldier of the conspersus 
"variety," still unknown, should prove the contrary. 

As far as the systematic placement of the present species is 
concerned, it is obvious that Emery's proposal (1922, I.e.) is 
not any longer acceptable. Hence it must be transferred from 



110 ENTOMOLOGICAL NEWS [April, 1958 

the spinosus-group in the subgenus Paracryptocerus s. str., to 
the angustus-group in the subgenus Hamcdia, to which it doubt- 
less belongs. 

Paracryptocerus minutus (Fabricius) 

1804. Cryptocerus minutus Fabricius, Syst. Piez., p. 420. 
1867. Cryptocerus exiguus F. Smith, Trans. Ent. Soc. Lon- 
don (3) 5: 524. New Synonymy. 
1951. Paracryptocerus minutus Kempf, Rev. de Ent. 22: 169. 

The examination of the holotype specimen of exiguus , a 
worker from Mexico, revealed at once its identity with the 
common and widespread minutus. The present specimen has 
a slightly, yet insignificantly, broader head, a feature which I 
have observed in other minutus specimens from Mexico. There 
is not the slightest doubt concerning this synonymy. 

Paracryptocerus scutulatus (F. Smith) 

1867. Cryptocerus scutulatus F. Smith, Trans. Ent. Soc. Lon- 
don (3)" 5: 524. 

1867. Cryptoccrus angulosus F. Smith, Trans. Ent. Soc. Lon- 
don (3)" 5: 524.

311. 

1951. Paracryptocerus scutulatus Kempf, Stud. Ent. n. 1, 
p. 26. 

This synonymy (scutulatus -- soldier; angulosus -- worker of 
the preceding species) has already been established by Emery 
from the original diagnoses. The examination of both holo- 
types involved confirms definitively this step.

Review 

STUDIES ON THE COMPARATIVE ETHOLOGY OF DIGGER WASPS 
OF THE GENUS BEMBIX. By Howard E. Evans. Pp. 1-248, 
52 figs. Comstock Publishing Associates, Ithaca, N. Y., 1957. 
Price, $4.75. 

Thirteen North American species are described and com- 
pared. First the behavioral patterns common to the genus are 
discussed ; then each species is described in detail, with a great 
deal of original data in addition to information from the litera- 
ture. On the basis of this material, the behavioral patterns 
are analyzed in order to provide a phylogenetic approach to the 
question of why a certain species, for example, behaves as it 
does. The patterns (of mating, nest-building, etc.) are, of 
course, innate, although learning also plays a part in such activi- 
ties as orientation and hunting. In each species, not only is the 
nature of each activity studied, but the sequence of the chain of 
activities is analyzed and written as a formula, which represents 
the inherited neuro-motor pattern of the particular species. In 
addition to the behavior, the ecology of these wasps is analyzed 
and compared. 

Reasoning just as a morphologist would. Professor Evans 
selects ten pairs of behavioral characters in the genus, and in 
each case decides which alternative represents the more primi- 
tive, and which the more specialized behavior. On this basis 
he is then able to outline roughly the evolutionary pattern in 
the genus. Interestingly, there is a correlation between the 
behavioral characters and ordinary structural characters, so that 
Evans is willing to predict the behavior of certain as yet un- 
studied species of Bembix merely from their structure. 

This is an outstanding book, and is of fundamental significance 
because it treats of the evolution of behavior patterns, unequivo- 
cally, in the same manner as any neo-Darwinian would treat of 
the evolution of structural characters. It is so competently 
done, with the facts so clearly set forth and analyzed, that it 
should serve, incidentally, to exorcise finally the ghost of 
Lamarckianism that has continued to haunt discussions on the 
evolution of behavior in the Hymenoptera. R. G. SCHMIEDER.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
nacschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

Individual Identification Labels for Pinned Insect 

Specimens 

By GEORGE W. BYERS x 

Several months ago, a friend and I were examining types of 
a certain family of Diptera in a university museum. Each type 
series was pinned to the right hand side of a label which bore 
the name of the species, while each pinned specimen carried a 
red label reading merely "holotype," "allotype," or "paratype." 
My friend removed one of the paratypes from the end of its row, 
examined it with his hand lens, and pinned it back into the tray, 
failing, however, to notice that he had placed it in the wrong 
row, thereby erroneously indicating it to be a paratype of quite 
another species. Fortunately this accident was immediately 
discovered and corrected. But how often do similar accidents 
occur, involving perhaps less important specimens, because of 
the lack of an identification label on each pinned insect specimen? 

Collecting insects, somehow preserving them in the field, and 
in the laboratory pinning them and providing them with the 
essentials of collection data on labels all require little effort on 
the part of the entomologist, when time and expense are figured 
on a per-specimen basis. Identification, in contrast, usually 
involves a great amount of time and the expense of a library 
and other facilities appropriate to the problem at hand. Most 
collectors and curators, confronted with the task of species deter- 
mination, are left no choice but to turn to qualified specialists 
for help. (This is quite apart from the fact that more often 
than not identifications by specialists are the only ones likely to

INSTITUTION -'UN 1 2 1958 



114 ENTOMOLOGICAL NEWS [May, 1958 

be correct.) Usually, for nearly any taxonomic category, a 
competent and willing taxonomist can be located ; and in due 
time the specimens will be returned identified to the collector. 

A museum specimen the identity of which has been deter- 
mined by a qualified specialist has a much greater value than an 
unnamed specimen, but this value can easily be lost unless it 
is somehow permanently fixed. An identification label at- 
tached to the pin of only the first in a series of specimens seems 
to me to indicate an unwarranted faith in the infallibility of 
curators, technical assistants and all others who make use of 
collections in museums and other repositories ; it is an invitation 
to confusion ! After the taxonomist has arranged specimens 
in rows after an identification label (and some attach the deter- 
mination to the last specimen in the series), there remain many 
opportunities for errors to creep in, as specimens are transferred 
to shipping boxes and later are unpacked and put into their 
permanent boxes or trays. Whenever the collection is used for 
whatever reason, there is a chance that a specimen removed 
from its place in the tray may accidentally be returned to an- 
other place. And a specimen merely placed alongside one bear- 
ing a determination label, even though it has been examined 
and identified by a competent authority, has no more status, in 
fact, than any number of other specimens later added to this 
group by other persons perhaps not at all qualified to make the 
identification concerned. 

The logical solution to this problem is to attach an identifica- 
tion label to every specimen that has been identified. Such a 
label should indicate not only the genus and species (and sub- 
species, if any) but also the name of the person who made the 
identification and the date (year). 

This would seem at first to be visionary, perhaps, but in fact 
it is quite an attainable goal. By a process of photo offset 
printing, the Snow Entomological Museum of the University of 
Kansas at the present time is able to have such labels made at 
a cost of about ten for one cent. The desired labels are typed 
on ordinary white bond paper, one 8^ X 11 -inch sheet of which 
will usually provide space for about 50 kinds of labels. As a 



Ixix] ENTOMOLOGICAL NEWS 115 

measure of economy, four such sheets are photographed to- 
gether at the desired reduction of dimension and are printed in 
any number on high quality, stiff paper. Since both date-locality 
labels and identification labels are made at the same time, it is 
not necessary to withhold printing until a large number of kinds 
of identification labels alone are accumulated. Most of the cost 
in the process described is for preparation of copy (by electric 
typewriter at the University of Kansas), but it should be pointed 
out that any clear black line or typing on white paper will be 
satisfactory copy for photo offset printing. Cost is therefore a 
minor consideration, and certainly a specimen worth the time 
and effort required for identification is worth a label noting 
this work ! 

One very practical problem is that of the responsibility for 
attaching identification labels. As matters now stand, it usually 
falls to the curator of a collection to so label the specimens that 
are returned to him from various specialists. This situation has 
one serious disadvantage, namely, that it is more often the case 
than not that there will be very small numbers of specimens of 
most species, requiring either that most of the identification 
labels for that species be discarded or that blank labels (showing 
only the name of the authority and the date) be printed and the 
species' name be added by hand. The first of these alternatives 
is unsatisfactory for reasons of economy, and the second intro- 
duces a further chance of error in transcription of the name. 
It therefore seems to me that the responsibility for attaching 
identification labels to each and every specimen identified should 
pass to the determining authority. He should have in his 
possession supplies of these inexpensive labels for all species in 
his particular taxonomic group, so that only the last two digits 
of the date would need to be filled in. Persons doing a great 
deal of identification work might have even the date completed 
on the printed label. 

It seems not unreasonable to think that the taxonomist would 
actually prefer to render this service, for then he would have 
some assurance that the order he had worked so hard to create 
would be maintained and that mixing of specimens after they 



116 ENTOMOLOGICAL NEWS [May, 1958 

had left his hands would not result in confusion that could be 
attributed to him. Some taxonomists have argued with me that 
they are too busy to attend to the mere routine of attaching 
identification labels, but such a view would mean either that 
they consider the curator's time less valuable or that they do not 
believe in the desirability of fixing the identity of each specimen 
they have studied. (It might be suggested that surely one 
whose time is so valuable will have assistants!) Thus, if iden- 
tification labels are to be attached at all, the logical time and 
place for this to be accomplished is at the time of species deter- 
mination and in the laboratory where the identification is made. 

Should a taxonomist be working alone, that is, not as a mem- 
ber of an institution, preparation of labels might be more ex- 
pensive and less convenient. Such a taxonomist, however, 
might arrange to obtain labels from institutions for which he is 
making identifications. 

Who would think of placing specimens in a permanent collec- 
tion with a single date-locality label for each series of a species 
taken at one time and place ? Who would attach collection data 
and identification to only one microscope slide of a series, with 
only a notation that all slides between that one and a certain 
other one should be regarded as having similar data? Surely 
the logic and desirability of the identification label for each 
specimen identified is inescapable.

Acanthothrips palmi, A New Thrips from Brazil. 
(Thysanoptera: Phlaeothripidae) 

By J. DOUGLAS HOOD, Professor of Biology, Emeritus, 

Cornell University 

This species is named after Dr. Charles E. Palm, Director of 
Research and Director of the Experiment Station at the New 
York State College of Agriculture at Cornell University, my 
superior for many years. He has collected Thysanoptera on 
various occasions, both in the United States and in the Ameri- 
can tropics, and has been instrumental in getting material re- 
sulting from investigations of banana thrips by the United Fruit 
Company. The types are in the author's collection. 

Acanthothrips palmi, sp. nov. (figs. 1-5) 

Resembling nodicornis, only (among the dark blackish brown 
species with dark femora), in lacking a white vitta along the 
sides of the head and prothorax ; but differing from that species 
principally in the presence of a white dash across mesonotum 
behind middle, the lack of white spots in the fore angles of 
segments III-VIII of the abdomen, the absence of prominent 
setigerous tubercles on the cheeks, and the darker, stouter, and 
much shorter intermediate antennal segments. 

Female (macropterous). Length about 2.8 mm. (fully dis- 
tended, 3.6 mm.). Color blackish brown, without white mark- 
ings in head and abdomen, but with a white dash across meso- 
notum behind middle (this dash is always visible as a pale area 
in the integument, but the white substance underlying it quickly 
disappears in preservative) ; legs blackish brown, with tibiae 
paler (especially at ends) and tarsi nearly yellow; fore wings 
lightly washed with brown in anal lobe, along costa to beyond 
last subbasal seta, in median pocket, and thence along posterior 
margin to tip ; antennae blackish brown, darkest in segments I, 
II, VII, and VIII, segments III-V dappled with yellow along 
sides, III sometimes with extreme base of pedicel yellow, IV 
and V, and sometimes VI, yellow in basal third or more, VII 
often yellowish at base; internal pigmentation crimson. 



118 ENTOMOLOGICAL NEWS [May, 1958 

Head (fig. 1) typical, its total length about 1.3 times its 
greatest width across cheeks, 1.4 times that across eyes, and 1.6 
times the least width near base, broadest across cheeks at poste- 
rior margins of eyes ; surface finely polygonally reticulate in 
ocellar area and along inner margins of eyes, nearly smooth in 
the deep groove in front of median ocellus, lightly cross-striate 
with widely-spaced anastomosing lines which form a subreticu- 
lation on dorsum and cheeks, the latter thus relatively smooth ; 
cheeks without the usual outstanding tubercles, but with a few 
pale setae ; postocular setae pale brownish, dilated and divided at 
tip, short (48-51 /A), about as far apart (94-100 /x) as their 
distance from sides of head, arising about 29 ^ from eyes. Eyes 
typical, finely facetted, their dorsal length (in KOH-treated 
paratype) 155 /*, greatest width 91, least interval (opposite 
median ocellus) 72, least interval shortly behind posterior ocelli 
86. Ocelli of posterior pair slightly in advance of middle of

Grooming Behavior in Orthoptera * 
By S. K. GANGWERE 

Observations upon grooming behavior in the Orthoptera are 
but scantily represented in the literature. Only Allard (1929) 
has published upon this subject. His treatment is limited to 
the katydid Orchelimum vulgarc, and it includes nothing on the 
action of the individual mouthparts during the cleaning process. 
The obvious need for a better understanding of grooming has 
prompted the following report, which is based upon numerous 
observations made over a period of five years. 

METHODS OF STUDY 

Observations carried out in the field, with and without the 
use of binocular field glasses, contributed to an understanding 
of some of the more general aspects of grooming behavior but 
were unsatisfactory in the study of movements of the mouth- 
parts. Most of the following data, as a result, were taken in 
the laboratory. Two different methods were employed. First, 
Orthoptera were confined individually within small, rectangular 
glass chambers within which their activities were observed under 
a dissecting microscope. Second, motion picture photography 
was employed to analyze further the rapid and complex groom- 
ing of one species, the large cockroach Byrsotria fmnigata. The 
16 mm. camera used for this purpose was a Cine-Kodak Special 
II, fitted with a 63 mm. f2.7 lens and an 8 in. extension tube, 
and set at 64 frames per second. Illumination was provided by 
three Spencer microscope lamps fitted with heat filters to pro- 
tect the cockroaches. 

RESULTS 

Unpublished work by the author shows that there are, from 
both a functional and structural point of view, two basic types of 
mouthparts in the Orthoptera. Since grooming in these insects 

1 Contribution No. 18 from the Department of Biology, Wayne State 
University, Detroit 2, Michiean. 



124 ENTOMOLOGICAL NEWS [May, 1958 

is largely a function of the mouthparts, it is not surprising that 
there are also two grooming methods. The first method is used 
by cockroaches, camel crickets, katydids, crickets, etc. ; these 
forms have swollen, lobular distagaleae adapted for wiping 
minute food particles and juices into the mouth (fig. 1). The 
second method is used by locusts or short-horned grasshoppers ; 
these insects have flattened, plate-like distagaleae adapted as 
lateral lips but useless in feeding (fig. 2). The insects using 
the former grooming method are, in addition, generally charac- 
terized by comparatively long antennae and entire or non- 
emarginate labra ; those using the latter by comparatively short 
antennae and emarginate labra. 

Grooming by Method 1. During their periods of activity, 
the cockroach and other orthopterans having long antennae 
groom themselves frequently, sometimes as often as once or 
twice every ten minutes. In doing so, they follow closely the 
generalized pattern discussed below. Cleaning of the face is 
accomplished by the tarsi of either the right or left fore leg, 
depending upon the side to be cleaned. The underside of the 
tarsus is first pressed to the mouthparts, where the distagaleae 
and laciniae respectively wipe and scrape it, the activities of these 
pairs being synchronous. Whether or not the tarsus is wetted 
by saliva is difficult to say, but at least no moisture is evident 
upon its surface. The face is then wiped with a downward 
motion of the cleaned foot. As in grooming of appendages, the 
operation may be repeated several times on each side. Groom- 
ing of the wings, like that of the face, is carried out by the 
cleaned legs, in this case the hind ones. 

In cleaning an antenna it is caught by the fore foot of the 
same side and pulled downward and inward toward the mouth- 
parts, where it is held in a channel formed by the medial groove 
of the labium and by the crossed labial palpi. The apices of the 
maxillary palpi may touch the antenna to keep it oriented. Syn- 
chronously and rapidly the distagaleae wipe and the laciniae 
rasp the antennal surface. The incisor surfaces of the mandi- 
bles, which may be either together or apart, and the apical 
margin of the labrum may assist in cleaning as the antenna is 



Ixix] ENTOMOLOGICAL NEWS 125 

scraped against them. The antenna is pulled through by the 
antennal extensor muscles, perhaps aided by the ligula, which 
opens and closes, apparently carrying the antenna with it as it 
moves cephalad during closure. Each cleaning operation may 
last 30 seconds or more. 

The palpi are cleaned in much the same manner as the an- 
tennae. A maxillary palpus is flexed caudad and thrust into a 
channel formed by the crossed labial palpi. The terminal one 
or two segments are then cleaned in the foregoing manner by the 
distagaleae and laciniae. The labial palpi, because of their posi- 
tion, must be flexed cephalad and are not confined within a 
palpus-enclosed channel when they are cleaned. In all other 
respects their grooming is like that of the maxillary palpi. 

Nineteen species of non-acridoid Orthoptera were observed, 
but not all were seen to groom; therefore, the foregoing gen- 
eralized account of grooming behavior is based upon numerous 
observations in the following fourteen species, all of them show- 
ing remarkable similarity in their grooming pattern : 

Blattidae : cockroaches Tettigoniidae (cont.) 

Blattella germanica Neoconoccphalus ensigcr 

Byrsotria fumigota Orchelimum gladiator 

Parcoblatta pensylvanica Orchelimum volantum 

Scudderia f. jurcata 
Tettigoniidae : katydids 

Amblycorypha oblongifolia Gryllidae : crickets 

Amblycorypha rotundifolia Acheta pennsylvanica 

Conocephalus f. jasciatus Nemobius f. fasciatus 

Conocephalus nigropleurum Oecanthus angustipennis 

Grooming by Method 2. The short-horned grasshoppers 
groom themselves comparatively infrequently, and when groom- 
ing occurs it is done in such a manner that it is most difficult to 
observe, even in the laboratory ; thus, it is not surprising that 
a few details of the cleaning operation are yet imperfectly under- 
stood. These insects groom their faces and wings much as do 
cockroaches ; that is, by wiping the cleaned tarsus over the sur- 
face to be groomed. The flap-like distagaleae of these insects, 
however, are neither adapted nor used for cleaning ; thus, when 
the tarsus is applied to the mouthparts it is rasped by the 



126 ENTOMOLOGICAL NEWS [May, 1958 

laciniae, sometimes by the mandibles, and perhaps wetted by 
saliva. 

The comparatively short antennae of these latter insects are 
not cleaned directly by the mouthparts but by the tarsi. The 
grasshopper reaches up with a newly cleaned fore tarsus and, 
using its tarsal claws to ensnare the antenna of that side, presses 
the apical portion of the antenna against the ground or other 
surface upon which the animal is resting ; then, by pulling the 
head away from the tarsus, the insect draws the antenna from 
between the surface and the tarsal pads. The proximal part of 
the antenna cannot be groomed in this manner but must be 
rubbed by the cleaned fore tarsus of the same side of the body. 

Twenty-three species of acridoids were observed in this study, 
but not all were seen to groom; therefore, the foregoing gen- 
eralized account of grooming behavior is based upon observa- 
tions in the following six species, all of them showing remark- 
able similarity in their grooming pattern : 

Tetrigidae : grouse locusts Acrididae (cont.) 

Tettigidca lateralis parvipennis Chortophaga znridifasciata 

Encoptoloplius s. sordidus 

Acrididae : grasshoppers Mclanoplus conjusus 

Arphia sulphured Mclanoplus f.-r. jcmur-rubrum

Modern Orthoptera are known to have been derived from 
two major lines, the Protorthoptera and the Protoblattoidea

(Zeuner, 1939). Each of these has given rise to insects which 
utilize Grooming Method 1, but only the Acridoidea, a branch 
from the Protorthoptera, is composed of insects which utilize 
Method 2. In Method 1, used by such Orthoptera as cock- 
roaches, camel crickets, katydids, and crickets, the cleaning of 
the appendages, including the antennae, is primarily through 
the rapid, synchronous movement of the distagaleae and laci- 
niae. In Method 2, used by short-horned grasshoppers, the 
distagaleae are not used in cleaning, the laciniae and mandi- 
bles being used to complete the operation. In insects utilizing 
the latter method of grooming, antennal cleaning is accomplished 
by drawing the appendage from between the cleaned tarsal pads 
and the surface upon which the animal is resting. It is evident 
that there exists a close correlation between the insects' struc- 
ture, both antennal and mouthpart, and their grooming behavior.

on the wet rocks and in the constant spray of Vernal Falls, near 
the base, and on the south side of the stream. Here it was 
associated with abundant specimens of Elliptcra clansa Osten 
Sacken. It may be noted that this spot is the exact type locality 
for the Elliptera, where the species was found by Osten Sacken 
on June 11, 1876.* The habitat, in the eternal spray of the 
falls, has suggested the specific name of the present fly (to 
love mist).

Habitat. MONTANA. Holotype: J\ Sacajawea Park, Lemhi 
Pass, 7,400 feet, June 26, 1956 (C. P. Alexander). Paratopo- 
types: 3JJ. 

Named in honor of Captain Meriwether Lewis (1774-1809), 
co-leader of America's most famous exploring expedition. The 
type locality of the present fly is at the highest source of the 
Missouri River at Lemhi Pass, about 100 feet below the small 
spring whence the river arises as a small branch of Pass Creek. 
At this point the river is scarcely more than a foot across, with 
small swampy areas on either bank, where the present flies and 
many other species of crane-flies occurred. Lewis and Clark 
remained at this locality for nearly two weeks in August 1805 
while obtaining horses to enable them to continue westward to 
the Pacific. The note in Lewis's Journal under date of Mon- 
day, August 12th, 1805, reads: "At the distance of 4 miles 
further the road took us to the most distant fountain of the 
waters of the Mighty Missouri in surch of which we have spent 
so many toilsome days and wristless nights."- Original spell- 
ing retained. 

In the structure of the male hypopygium, particularly the 
outer spine of the basistyle, the species is nearly intermediate 
between Pcdicia (Pedicia) parvicellula Alexander on one hand 
and P. (P.} subobtusa Alexander on the other.

Paradelphomyia (Oxyrhisa) sierrcnsis is most nearly related 
to P. (O.) pacifica (Alexander) of northwestern North Amer- 
ica, differing most evidently in the structure of the male hypo- 
pygium, as described. The eastern Nearctic P. (0.) americana 
(Alexander) is nearly intermediate between the two western 
species in these characters.

Habitat. COLORADO (Rocky Mountain National Park). 
Holotype: Trail Ridge Road, 11,300 feet, July 30, 1955 (C. P. 
Alexander). Allotopotype: $, pinned with type. Paratypes: 
1 J 1 , 1 $, Beaver Creek at Milner Pass, 10,730 feet, July 19, 
1955 (C. P. Alexander). 

The types were collected at timberline among low shrubby 
willows, swept from the latter, Caltha, Cardamine, Senecio tri- 
angularis, and other herbs. The small streamlets flow through 
gravel beds among the willow thickets, dropping rapidly and 
flowing into the Cache la Poudre River far below. The para- 
types were found along Beaver Creek, near the ultimate source 
of the Colorado (Grand) River, where they were swept from 
the vegetation. The itinerary covering this part of field collect- 
ing in Colorado has been outlined elsewhere.* 

The most similar described species is Onnosia (Rhypholo- 
phus} bifidaria (Alexander). The present fly differs conspicu- 
ously in the structure of the male hypopygium, particularly the 
simple compact gonapophyses which are quite distinct from all 
previously described species of the subgenus. 

Molophilus (Molophilus) oligacanthus new species 

Belongs to the gracilis group, pubipcnnis subgroup ; general 
coloration dark brown ; antennae short in both sexes ; legs dark 
brown to blackened ; wings broad, macrotrichia of veins dark ; 
male hypopygium with tip of apical lobe of basistyle subacute; 
both dististyles with relatively sparse armature, the outer style 
without spinules on basal half ; phallosomic plate broadly obtuse 
at apex, the surface with delicate setulae. 

<. Length about 4.5^-.6 mm. ; wing 5.2-5.7 mm. ; antenna 
about 1.1-1.2 mm. 

5- Length about 5-5.2 mm. ; wing 5.S-6 mm. 

Rostrum brown ; palpi dark brown. Antennae relatively 
short, brown to brownish black ; flagellar segments long-oval, 
the basal ones with very long verticils. Head light brown.

Thorax varying from light to dark brown, the pleura more 
pruinose. Halteres yellow. Legs with the coxae and tro- 
chanters yellow ; remainder of legs dark brown to blackish. 
Wings broad, subhyaline, the prearcular field more yellowed; 
veins pale brown, macrotrichia dark brown. Venation : R 2 
lying distally to r-m ; petiole of cell M 3 from one and one-half

Abdomen dark brown, hypopygium more yellowed. Male 
hypopygium much as in spiculatus, differing in details. Apical 
lobe of basistyle moderately slender, tip subacute, the setae not 
including the apex. Both dististyles with relatively sparse 
armature ; outer style without spinules on basal half, on outer 
part these restricted to the upper edge and ventral margin ; 
inner style longer, strongly curved beyond midlength, as in 
spiculatus; spines relatively large but scattered and few in 
number, especially on the outer or convex side. Phallosomic 
plate broadly obtuse at apex, surface with delicate setulae. 

Habitat. CALIFORNIA. Holotype: J 1 , somewhat teneral, 
Coldwater Creek above Lake Mary, Mammoth Lakes District,

Allotopotypc: $, July 5, 1957. Paratopotypcs: Several <$$, 
July 5-6,' 1957. 

The type series was taken in an extensive boggy area that 
included small cold sunken streamlets flowing into Coldwater 
Creek. The sparse tree cover included chiefly lodgepole pine 
and mountain hemlock ; shrubs and herbs chiefly Kalmia, Led it in 
and Phyllodoce, with Veratrnm, Allhtm and Sa.i'ijraga, growing 
amidst abundant short sedges and rushes and among dense 
mosses. Associated crane-flies included Limonia (Linionia) 
venusta (Bergroth), Ornithodes brevirostris Alexander, Limno- 
phila occidens Alexander, Gonomyia (Gonomyia} bihamata 
Alexander, Erioptera (Mesocyphona) mclanderiana Alexander, 
Erioptera (Psiloconopa) rainieria Alexander, and many others. 

The most similar species is Molophilus (Molophilns} spicu- 
latus Alexander, which is most readily separated by the details 
of structure of the male hypopygium, particularly the armature 
of the dististyles.

Dodds's Types for Two Species of Callibaetis 
(Ephemeroptera) 

By THOMAS B. THEW, Davenport Public Museum, 
Davenport, Iowa 

Two species of mayflies, Callibaetis vitreiis and Callibaetis 
fuse us, were described by Dodds in 1923 (Trans. Amer. Ent. 
Soc. 49: 93-114) in the results of his studies on the fauna of 
Colorado. Unfortunately, not only were the original descrip- 
tions extremely terse, but also no designation of a type for one 
species was made. In the Biology of Mayflies (Ithaca, New 
York, 1935), Traver pointed out that C. vltreus Dodds was a 
primary homonym of C. vitreus Navas and so renamed the 
former species C. doddsi. She could not place either of Dodds's 
species correctly, however, for the necessary detailed descrip- 
tions were lacking. Through the kindness of Harold J. Grant, 
Jr., of the Academy of Natural Sciences of Philadelphia, the 
author has been allowed to examine Dodds's material of these 
two ephemerids. Consequently, I hereby designate the male 
(Acad. Nat. Sci. Phila. type no. 9026), of the syntypical series 
of one male, one female, and one nymph as the lectotype of 
C. fnscns Dodds. I have also examined the single type, a male 
(Acad. Nat. Sci. Phila. type no. 9027) of C. z'itrens Dodds 
[== C. doddsi Traver]. A detailed description of each species 
will be given in a subsequent paper. 



Halysidota tessellaris S & A and Pollenia 

By S. W. FROST, Pennsylvania State University 

In making counts of Halysidota tessellaris taken from light 
traps operated during the summer of 1957, the writer noticed 
that many had pollenia attached to the tarsi of the legs. The 
moths were first noticed at the light traps in numbers on June 
30. At that time it was not suspected that specimens with 
pollenia would later be taken abundantly and it is possible that 
a few moths with pollenia escaped notice. By July 3 the prob- 



138 



ENTOMOLOGICAL NEWS 



[May, 1958 



lem became evident and thereafter counts were made daily 
until August 18. 

Several interesting observations were made. There were no 
milkweed plants, the only group of plants bearing pollenia in 
our area, near the location of the light traps. The moths must 
have travelled a considerable distance to reach the traps. Nu- 
merous insects bearing pollenia have been observed by the 
writer and by others but as far as known there is no mention 
of Halysidota tessellaris visiting milkweed. The larvae are 
known to feed on maple and many other trees. Frequent ex- 
aminations of milkweed during the summer failed to reveal the 
presence of these moths. They are strong fliers and are never 
trapped as is the case of some of the small moths. Milkweed 
pods were well formed by August 2. After that date moths, due 
to seasonal conditions, were scarce and none bearing pollenia 
were recovered. It is evident that males came to light more 
frequently than females and apparently males visit milkweed 
more often than females. It is also interesting to note that none 
of the other species of moths captured in light traps bore 
pollenia.

Retirement of Francis Hemming 

"FRANCIS HEMMING, Honorary Secretary to the International 
Commission on Zoological Nomenclature since 1936, is retiring 
from office on account of ill-health, according to an announce- 
ment of the International Trust of Zoological Nomenclature. 
In consultation with Sir Gavin de Beer, Director of the British 
Museum (Nat. Hist.), and President of the coming 15th Inter- 
national Congress of Zoology, the Trust has arranged for R. V. 
Melville, a senior member of the paleontological staff of the 
Geological Survey, London, to be released by the Survey for one 
year, to take charge, beginning May 1, of the Office of the Com- 
mission, with the title: "Assistant Secretary to the Director of 
the Office of the International Commission on Zoological No- 
menclature." Sir Gavin has also asked Mr. Melville to act as 
Recorder for the Section on Nomenclature of the International 
Congress of Zoology meeting next July. 

In order that Mr. Melville may concentrate on urgent tasks 
relating to the coming Colloquium on Zoological Nomenclature, 
Mr. Hemming has consented to complete certain work already 
begun, including the printing of the Lists and the Indexes, and 
the Opinions on decisions already taken. One of the first duties 
of the new Secretary will be to find suitable accommodation for 
the Office, hitherto housed rent-free in Mr. Hemming's private 
residence.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castor aeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schisuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schisur aeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

Three New Aphid Parasites from the Pacific Coast. 
(Hymenoptera: Braconidae, Aphidiinae) 

By C. F. W. MUESEBECK, U. S. Xational Museum 

Recently I received a large collection of nicely preserved 
Aphidiinae for identification from Dr. Evert I. Schlinger, of the 
Citrus Experiment Station, Riverside, California. The speci- 
mens had been reared from various aphid hosts and included 
three new species, two of them in long series. All three are 
described here. 

Aphidius (Protaphidius) ponderosae, new species 

In Smith's key (1944, Contrib. Zool. Ent., Ohio State Univ., 
Xo. 6, p. 37) this species runs to californicus Ashmead. It 
differs conspicuously from that species, however, in being much 
larger, and in having the mesoscutum delicately sculptured and 
the metacarpus nearly as long as the stigma. In californicus the 
mesoscutum is smooth and polished and the metacarpus is only 
half as long as the stigma. 

I'cmale. Length about 3.5 mm. Head strongly transverse 
and noticeably wider than the thorax ; face more than three 
times as broad as long from antennal foramina to base of cly- 
peus, usually with a little weak and indefinite roughening below 
antennae ; malar space one-third as long as eye ; temples strongly 
receding from the eyes ; antennae with 20 to 22, usually 20, 
segments ; ocellocular line about three times as long as diameter 
of an ocellus. 

Mesoscutum very delicately coriaceous and subopaque ; no- 
taulices weak but usually distinct ; scutellum smooth and pol-

ished ; propodeum largely smooth but usually with a little weak, 
indefinite sculpture ; a median longitudinal carina on dorsal face 
of propodeum, and from its caudal end a transverse carina 
extending each side to the spiracle ; longitudinal carinae on 
posterior declivity of propodeum wanting, and the areola, there- 
fore, incomplete ; pleura smooth and polished. Stigma hardly 
twice as long as broad ; metacarpus nearly as long as stigma ; 
stub of second abscissa of radius not, or barely, longer than 
intercubitus. 

Abdominal petiole weakly rugulose, except basally and just 
before apical margin where it is smooth ; remainder of abdomen 
smooth. 

Male. Essentially like the female, but antennae with 21 to 
23, usually 22, segments. 

Type. U. S. National Museum No. 64229. 

Type-locality. Cold Spring Camp, Allison Pass, Hozameen 
Mts., in E. C. Manning Provincial Park, New Westminster 
Sector, BRITISH COLUMBIA, elev. 4,450 ft. 

Described from 21 females, including holotype, and 11 males 
reared from Cinara sp. on Finns ponder osa by Evert I. Schlinger, 
June 4, 1957. 

Aphidius (Aphidius) alius, new species 

This is apparently very similar to confusus Ashmead, where 
it will run in Smith's key (1944, Contrib. Zool. Ent., Ohio 
State Univ., No. 6, p. 51). Unfortunately, the holotype and 
only known specimen of confusus is headless, and a thoroughly 
satisfactory comparison is, therefore, impossible ; but the present 
species differs from that incomplete type specimen in having all 
coxae yellow and the abdomen behind the petiole piceous to 
black ; in the type of confusus the hind coxae are black and the 
abdomen is almost entirely testaceous. In addition, the new 
species has the metacarpus considerably shorter in relation to 
the length of the stigma than it is in confusus. From nigritelens 
Smith, which it also closely resembles, it may be distinguished 
by its much shorter metacarpus, which is not longer than the

Trioxys (Acanthocaudus) schlingeri, new species 

This is the third Nearctic species of the subgenus Acantho- 
caudus. It closely resembles tissoti Smith, but it lacks the dis- 
tinct, median longitudinal carina on the basal half of propodeum 
which distinguishes that species ; and the eyes are more definitely 
convergent below.

mina ; temples convex, not receding from the eyes ; antennae 
12-segmented, the first flagellar segment slightly the longest, the 
apical segment usually a little the shortest, the remainder sub- 
equal.

Increase in Subscription Rates for 1959 

The cost of printing and distributing ENTOMOLOGICAL NEWS 
has been increasing greatly in recent years. Only the steady 
growth of our subscription list, and the additional income from 
the sale of runs of back volumes during these years has made it 
possible to keep the subscription rate at the same figure for the 
past six years. Now, however, some additional income will 
have to be secured. 

Beginning January 1959 (Vol. 70) the subscription rate to 
libraries, laboratories, and institutions of every sort will be 
$6.00 per annual volume ($6.30 foreign, $6.15 Canada). 

Private subscriptions for personal, individual use will remain 
at the same rate as heretofore, i.e., at $5.00 ($5.30 foreign, 
$5.15 Canada). 

By this arrangement, there will be no decrease in individual 
subscriptions of the many amateur and professional entomolo- 
gists who read the NEWS, and, it is hoped that many younger 
enthusiasts, especially students, will be encouraged to subscribe. 
By thus maintaining a large circulation, even if in part at a 
reduced rate, the costs will be more broadly spread to the ulti- 
mate benefit of institutional as well as individual subscribers.

Some Previously Undescribed Males and New Sex 

Associations in the Pompilinae (Hymen- 

optera: Pompilidae) 

By HOWARD E. EVANS, Cornell University, Ithaca, N. Y. 

Although the classification of the Nearctic Pompilidae has 
undergone many refinements in the past fifteen years, there 
remain a number of species known from only one sex. The 
purpose of the present paper is to describe the previously un- 
known males of Pompilus perfasciatus Evans and A poms be- 
quaerti (Banks) and to place in synonymy a species previously 
known from only the male sex, Psorthaspis albocaudata (Mai- 
loch). Knowledge of the male of A poms bequaerti raises cer- 
tain questions regarding generic limits in the Aporini ; these 
are discussed at the end of the descriptive material. 

Pompilus (Perissopompilus) perfasciatus Evans 

Pompilus (Perissopompilus} perfasciatus Evans, 1951, Trans. 
Amer. Ent. Soc. 77: 225-226; Evans, 1953, Ann. Ent. Soc. 
Amer., 46: 531. 

This species has been known from only two females, both 
from Riverside Co., Calif. On April 18, 1957, Dr. R. M. 
Bohart, of the University of California at Davis, took a series 
of three females and two males in dunes in Borrego Valley, San 
Diego Co., Calif. Interestingly enough, Dr. Bohart took four 
females and thirteen males of P. (P.) phoenix Evans, the only 
other known species of this subgenus, at the same time and place. 

The male perfasciatus is readily separable from that of phoe- 
nix by virtue of the complete coalescence of the second and 
third transverse cubital veins, leaving only two submarginal 
cells ; in addition, the apical fuscous band of the fore wing is 
smaller and the body pubescence much coarser. The terminalia 
agree in general pattern with those of phoenix, but there are 
some notable" specific differences. 

Description. Length 3.5-4.5 mm. ; fore wing 2.5-3.5 mm. 
Black; wings hyaline and with a whitish bloom, a brown band 
occupying the apical .2 of the fore wing ; this band barely reaches 



148 ENTOMOLOGICAL NEWS [June, 1958 



the tip of the marginal cell and posteriorly fades out before 
reaching the subdiscoidal vein. Entire body clothed with a 
coarse silvery pubescence, including the scape and the legs to 
the femora ; pubescence especially prominent on the temples, 
posterior margin of pronotum, mesopleura, sides of the pro- 
podeum, and the hind coxae ; pubescence on abdominal tergites 
directed backward except in broad apical bands, where it tends 
to diverge from the median line. 

Head broad, the transfacial distance about 1.2 times the facial 
distance. Antennae relatively short, the first four segments in 
a ratio of about 10:4:4:5, segment three no longer than thick. 
Ocelli small, in a large triangle, the postocellar line greater than 
the ocello-ocular line as 8:5. Posterior margin of pronotum 
arcuate. Legs weakly spinose, the middle tibiae, however, with 
several fairly strong spines. Fore wing with the marginal cell 
slightly more than twice as broad as high, removed from the 
wing-tip by about 1.5 times its own length; second submarginal 
cell 1.5-1.7 times as broad as high; third submarginal cell ab- 
sent ; second submarginal cell receiving the second recurrent 
vein at or just basad of its outer apical corner. 

Abdomen slender and with a strong tendency for the apical 
segments to telescope within the basal three segments. Sixth 
sternite with a broad, rectangular emargination which is flanked 
by a pair of thick, two-pronged spines ; disc of this sternite with 
a pair of weak lateral carinae, but without the distinctly marked 
off median area of phoenix. Subgenital plate (fig. 2) shaped 
much as in phoenix but without the basal lateral expansions of 
that species. Genitalia (fig. 1) very similar to those of phoenix 
but differing as follows : parameres somewhat thicker and with a 
prominent squama about one-third the distance from the apex ; 
parapenial lobes with a series of weak serrations along their 
inner margin ; aedoeagus with the apex only weakly expanded.

Ixix] ENTOMOLOGICAL NEWS 149 

Malloch's albocaudata has remained in limbo since its de- 
scription. Bradley (1944, Trans. Amer. Ent. Soc. 70: 152), on 
the advice of Banks, assigned the species to Allocy phony. v. I 
removed it to Psorthaspis (1954, Amer. Mus. Novitates no. 
1662, p. 15), but was unable to place it properly because of the 
fact that the tips of all the tarsi are absent in the type and only 
known specimen. 

The collections of the California Insect Survey contain a 
number of male specimens of planata from Borrego, San Diego 
Co., Calif., in which the apical abdominal tergites bear whitish 
pubescence. In some specimens the white is very limited, in 
others it covers all of the tergites beyond the third. This sug- 
gested to me that the type of albocaudata (from Higley, Ariz., 
U. S. Nat. Mus. no. 27432) might be merely a "white-tailed" 
planata. Re-examination of the type reveals that it is indeed 
planata, with the characteristic elevation of the ocellar triangle 
and other features of this species. The white pubescence begins 
on the posterior part of the third tergite, so it is somewhat more 
extensive than in any specimen from Borrego. P. planata is 
apparently rare in Arizona ; I have seen a few females but no 
males other than this one. Whether all males from Borrego 
eastward are "white-tailed" and whether the name albocaudata 
should be retained in a subspecific sense remain to be determined.

This species has been known from only a few females from 
eastern Mexico and southern Texas. For several years I have 
been aware of the occurrence of an unknown male Aporus in 
this area. On June 24, 1956, I collected three specimens of this 
unknown male on the flowers of Avicennia nitida near Port 
Isabel, Cameron Co., Texas, in close association with two female 
bequaerti. I think there can be little doubt that it represents 
the male of bequaerti. 



150 ENTOMOLOGICAL NEWS | June, 1958 

These males run directly to calcaratus (Fox) in Bradley's key 
to the species of Aporus (1944, Trans. Amer. Ent. Soc. 70: 89). 
I have recently examined the type and only known specimen of 
calcaratus in the Academy of Natural Sciences of Philadelphia 
("S. Fla., Robertson," type no. 4721). The two species are 
actually very different and may be separated as follows : 

Second recurrent vein reaching the cubitus well apicad of the 
second transverse cubital vein ; propodeum nearly flat in front, 

with a short, steep declivity behind ; length 6.5-14 mm 

bequaerti (Banks) 

Second recurrent vein reaching the cubitus at the same point as 
the second transverse cubital vein (in the left wing of the 
type, apicad of it by half the width of the vein) ; slope of pro- 
podeum low and even; length 5.5 mm calcaratus (Fox) 

Description. Length 6.5-14 mm.; fore wing 5.5-10.5 mm. 
Black, the tibial spurs white and the apical abdominal tergite 
with a white spot ; body very extensively clothed with a fine 
silvery pubescence, more coarse and suberect on the posterior 
part of the propodeum ; wings hyaline, the apical margin of the 
fore wing narrowly infuscated. 

Clypeus slightly less than twice as broad as high, its apical 
margin weakly convex. Front relatively narrow, the middle 
interocular line .63 times the transfacial line. Ocelli in a broad 
triangle, postocellar line greater than ocello-ocular line as 7:5. 
First four antennal segments in a ratio of about 8:2:8:9, seg- 
ment three slightly less than twice as long as thick. Pronotum 
long, its posterior margin arcuate but with a small median angu- 
late notch. Propodeum rather long, its median line weakly 
impressed, its posterior declivity short and steep. Legs slender, 
the tibiae and tarsi with many small black spines ; longer spur 
of hind tibia .62 times the length of the hind basitarsus. Wings 
with the transverse median and basal veins interstitial or nearly 
so ; marginal cell acute apically, removed from the wing-tip by 
considerably less than its own length ; second submarginal cell 
about twice as broad as high ; second recurrent vein meeting the 
cubitus beyond the second transverse cubital vein by about half 
the length of the latter vein.

REMARKS ON GENERIC LIMITS IN THE APORINI 

As I indicated above, the male bequaerti runs to calcaratus in 
Bradley's key to the species of Aporus. But the fact is that 
neither of these species will run to Aporus in his generic keys. 
Either these species do not belong in Aporus or some modifica- 
tion of our interpretation of this genus is necessary. 

In the case of calcaratus (Fox), the venational features men- 
tioned above would seem to place it in Aspidaporus Bradley, 
known only from Brazil. I have compared the type of calcaratus 
with a paratype of Aspidaporus niinusculus Bradley. The two 
specimens are so similar they might almost be conspecific. 
However, since the male genitalia of calcaratus have never been 
studied and the female is unknown, no accurate generic assign- 
ment of this species can be made at this time. Presumably the 
female will be found to possess the unusual antennal fossae and 
the margined pronotal disc of Aspidaporus. If it does not, then 
additional characters for the separation of the males of these 
genera must be sought. 

On the other hand, the male bequaerti (Banks) runs in 
Bradley's key to Odontaporus Bradley, since the parameres are 
straight and do not reach the apex of the parapenial lobes. 
(Actually the parameres are somewhat intermediate in form 
between Aporus and Odontaporus.} This fact has led me to 
re-examine the mandibles of the female bequaerti, and I find that 
they possess a tooth on the lower margin (fig. 5) . Although this 
tooth is not as large as in the species which Bradley assigned 
to Odontaporus, it is nevertheless distinct in all of the speci- 
mens I have seen. As a matter of fact, some evidence of such 
a tooth is visible in freshly emerged specimens of Aporus niger 
(Cresson). Although Bradley supported his separation of 
Aporus and Odontaporus with color characters, he himself rec- 
ognized certain exceptions to these color differences. In my 
opinion the species placed by Bradley in Odontaporus represent 
an early invasion of one or more stocks of Aporus (s. str.) into 
Central America and the Antilles, where these forms became 
isolated and specialized with respect to color, mandibular struc- 
ture, and genitalia. As a subgenus, Odontaporus seems to me 



Ixix] ENTOMOLOGICAL NEWS 153 

considerably weaker than Bradley's subgenera Notoplaniceps 
and Ncoplaniceps. In my opinion Odontaporus Bradley, along 
with Mclanaporus Ashmead, which is an earlier name for the 
same group, should be placed in the synonymy of Aporus, sub- 
genus Aporus. 



A New Schendylid from the Eastern United States, 

with Notes on Distribution and Morphology. 

(Chilopoda : Geophilomorpha : Schendylidae) 

By RALPH E. CRABILL, JR., Smithsonian Institution, 
Washington, D. C. 

The chilopod fauna of the central and southern Appalachians, 
including parts of the adjacent Cumberland Plateau, seems to 
be comprised of several rather distinct components. Apart from 
recent artificial introductions and endemic elements of uncertain 
geographical affinity, two fairly heterogeneous factions stand out, 
groups having an affinity with eastern Asia and, or, northwest- 
ern America, and those with an affinity with the southwestern 
United States, and, or, lands to the south, principally Mexico. 

The implication is that this area in the southeastern United 
States today shows the influence of earlier faunal movements, on 
the one hand, from the south, and on the other, from the Ameri- 
can northwest, and ultimately from Asia. 

Examples of the northwestern and Asian contribution are 
found in the following : Strigamia, Arctogcophilus, Gcophilus, 
Escaryits, Scolopocryptops (except gracilis), Zygethobhis, Zy- 
gethopolys, Bothropolys, and perhaps the majority of the Litho- 
biidae (sens. str.). A southern derivation is suspected for some 
of the species of: Gosiphilus, Arcnophilus, Nyctunguis, Scolo- 
pocryptops (gracilis), Scolopendra (viridis and polymorpha), 
Thcatops, Cryptops, all of the Gosibiidae and Watobiidae, a few 
Lithobiidae such as Neolithobius and Enarthrobius, and some 
Henicopidae, notably Lamyctcs and Buethobius. I do not mean 
to imply that a given group arose, was evolved, in either region 
although some must have been but merely that both regions 



154 ENTOMOLOGICAL NEWS [June, 1958 

independently and probably at different times contributed to the 
existing centipede fauna of the lower Appalachians and adjacent 
areas. 

To the southern component belongs the present new species, 
Nyctunguis pholeter, whose known congeners are especially 
characteristic of the North American southwest and Mexico. 
Apart from this rich fauna, two other species are known, one 
from the Leeward Islands, and another, rather aberrant form 
from Turkey. 

The presence of Nyctunguis in the southern Appalachians 
suggests an ancient dispersal from the south, possibly from 
Mexico, and perhaps parallels the case of the himantariid Gosi- 
pliiliis euphorion Crabill, whose closest relatives flourish on the 
Pacific coast south to Mexico. A third species linking the Cum- 
berland Plateau with the far west is Zygethopolys atrox Crabill 
whose affinities, by contrast, are with the Pacific northwest, 
Alaska, and Asia. 

On the basis of the original description, the Californian Nyc- 
tunguis glcndorus Chamberlin seems most like pholeter. Pos- 
sibly the most important distinctions between the two are : 
glendorus, median labral arc short, about ^ of the labral width, 
pholeter, median arc wider, about ^ the labral width ; glendorus, 
dentate lamella in three blocks each with three teeth, pholeter, 
dentate lamella very vaguely divided into two blocks, with two 
and eight teeth respectively.

with its pleurites. PLEURAL REGION : (fig. 12). Series 4 alpha 
and beta absent; series 5 absent (suppl. note 5). 

SUPPLEMENTARY NOTES 

1. MANDIBLE. The cleft in the dentate lamella is sufficiently 
obscure to be overlooked easily, and in fact it may even be an 
artifact, as may be its counterparts in a number of the cases 
noted in the literature. Though the question of whether or not 
a given schendylid dentate lamella is divided or not seems im- 
portant, in my opinion (and at this time) the significance for 
systematics of the number and kind of divisions has yet to be 
demonstrated. 

2. IST MAXILLARY LAPPETS. Attems (in Das Tierreich, 
Lief. 52, p. 87, 1929) describes the known members of Nyctun- 



lxix| ENTOMOLOGICAL NEWS 157 

guis as lacking 1st maxillary lappets, possibly because (1) he 
had never directly studied a specimen, or (2) they had never 
been ascribed to any species in the literature, or (3) perhaps 
because Verhoeff's figure of the maxillae of N. dampfi suggests 
them to be absent. In addition to pholcter, I have examined 
several Californian congeners and have found well-developed, 
though frequently concealed, lappets in all cases. 

3. SENSILLA BASICONICA OF THE UNGULA. Microscopic ex- 
amination of the claws of the prehensors and 1st maxillae dis- 
closes the presence of numerous minute canals extending through 
the exoskeleton and connecting the body surface with its inte- 
rior. Having observed them in all of the chilopod orders, I was 
at a loss to imagine their function, unless they were glandular 
canals of some sort. However, S. L. Tuxen of Denmark seems 
indirectly to have explained their presence correctly. In the 
course of his study of similar canals in the chelicerae of a 
solpugid, he observed that each is capped by a minute hyaline 
cone and therefore suggested that they are sensory in nature 
and probably chemoreceptors. Subsequently I found the same 
hyaline cones in centipedes. These structures then are probably 
the modified counterparts of the sensilla basiconica of insects. 

4. PRETARSAL ACCESSORY SPINES. I have found the same 
remarkably large pretarsal accessory spines in several Pacific 
coast members of the genus, though in these they are more 
prominent than in pholcter, being darker and heavier. I have 
observed such conspicuous accessory spines in no other Geo- 
philomorpha, nor have I read of them in connection with any 
other species, with the possible exception of the Neogeophilidae. 
Their presence, especially in a schendylid, may actually be quite 
meaningful, since they may be homologous with the pretarsal 
accessory (articulated) spurs of the more primitive orders, e.g., 
Lithobiomorpha and Scolopendromorpha. If this is so, then 
they represent still another primitive feature testifying to the 
evolutionary conservatism of the Schendylidae within the 
Geophilomorpha. 

5. THE PLEURAL REGION. The system of pleurite nomen- 
clature used here is that of Broelemann. It is explained in 



158 ENTOMOLOGICAL NEWS [June, 1958 

Faune de France, 25 : 45, 1930 ; examples of its use may be 
found in Broelemann and Ribaut, Nouv. Arch. Hist. Nat., 
Paris (5) 4: 53-183, 1912. In addition to one other work 
by a different author, their "Essai d'une Monographic des 
Schendylina" in my opinion still stands as one of the two most 
detailed, orderly, best illustrated, and in some ways most search- 
ing preliminary analysis ever accorded a group of centipedes 
during the hectic history of their study. 

SLIDE PREPARATION WITH HOVER'S MOUNTANT 

It has been my experience that treating the delicate mouth- 
parts in weak KOH or even in the gentler NaOH too often 
results in the distortion or partial (or complete) destruction of 
certain critical structures such as the labral teeth and fimbriae, 
parts of the maxillae, and the prehensorial ungula. This prob-

lem may usually be resolved through the use of Hoyer's mount- 
ing medium, a semi-permanent (though possibly permanent) 
mountant that is gaining an increasing following among zoolo- 
gists. 

It offers a number of desirable advantages apart from its 
ability to preserve and clear without distortion or destruction. 
Parts may be transferred to it directly from alcohol, water, or 
glycerine without preliminary treatment. It permeates the 
specimen rapidly and thoroughly, clearing it beautifully at the 
same time. It neither discolors with age nor crystallizes. It 
may be thinned with distilled water repeatedly. 

As to procedure, one simply covers the object with the 
mountant in the usual manner on a microscope slide and then 
applies a plain or supported cover glass. Gentle Jieating for 
one to two hours is most desirable as it speeds clearing, insures 
uniform penetration without the formation of internal bubbles, 
and hastens hardening of the exposed mountant. To counter- 
act the mountant's chief disadvantage, its tendency to shrink, 
after a day or so ring the preparation with fresh Hoyer's, and 
when this has set, ring it once or twice with some standard 
ringing mixture, such as murrayite. 

As to permanency, slides of mites prepared with Hoyer's in 
this museum twenty years ago remain in perfectly acceptable 
condition today. The formula is as follows : 

distilled water 50 ml. 

gum arabic 30 grams 

chloral hydrate 200 grams 

glycerine 20 grams 

The materials go into solution slowly, so that intermittent stir- 
ring over a period of several days is often necessary. Mix in 
the order given.

Mexican Jungle and Desert Fleas with Three new 

Descriptions 

By C. ANDRESEN HUBBARD, Tigard 23, Oregon 

I have before me at this time the results of two collections of 
fleas from Mexico. Dr. Murray Johnson, physician and sur- 
geon, and well known west coast mammologist of Tacoma, 
Washington, collecting 35 miles north of Los Mochis on the 
border between Sinoloa and Sonora, Mexico on March 23, 1954, 
removed 

Orchopeas s. fireman! Hubbard, 4 males and 5 females off 

Tcanopits phcnax (woodrat), and on March 12-14, 1956 at 

Alamos, Sonora ; 
Echidnophaga gallinacea (Westwood), 4 males, 12 females off 

Brassariscus astulus (ringtail cat) ; off Didelphis m. mesa- 

mericamts (opossum), 61 males, 353 females; 
Pulex simulans Baker, 10 males, 8 females off Brassariscus 

austulus; 31 males, 35 females off Didelphis m. mesaincri- 

canus and off Citcllus y. rupestis (ground squirrel), 10 males, 

12 females; 
Ctenocephalides f. felis (Bouche), 1 male and 2 females off 

Didelphis m. mcsarnericanus. 

It is to be noted in the above that for the first time in over 
50 years the determination of Pulex simulans Baker has been 
used. Mr. Frans Smit of the British Museum, who studied 
the fleas involved, thinks he has found the characteristics upon 
which Baker made the original description in 1895. Practically 
all investigators to date have considered P. simulans a synonym 
of P. irritans. Smit is quite serious in his contention that P. 
simulans is a good species and has determined Pulex from cen- 
tral California for the writer as P. simulans. 

The second collection before me was made by Mr. C. Hayden 
formerly of Riverdale, California but whose present whereabouts 
is unknown to the writer. During December of 1955 and Janu- 
ary and February of 1956 Mr. Hayden was collecting about 
Mexico City. Six areas were visited, 14 different hosts ex- 



162 ENTOMOLOGICAL NEWS [June, 1958 

amined, and the 24 vials of fleas collected represented 16 species 
and subspecies, 3 of which are considered new and described 
herewith as such. Upon the arrival of the materials the writer 
examined same without clearing and noticed the bulk of the 
fleas were of the genera Kohlsia, Jellisonia, Pleochatis and 
Polygenis. These genera being unfamiliar to the writer, the 
entire collection was forwarded to the British Museum for con- 
sideration. The results, now indexed, are as follows : 

Pulex irritans L. off Urocyon cinereoargcnteus (fox), 2 males, 

Pueblo Nuevo, Chiapas, Feb. 6, 1956. 
Ctenocephalides canis (Curtis) off Urocyon cinereoargenteus, 

3 pairs, Pueblo Nuevo, Chiapas, Feb. 6, 1956. 
Ctenodephalides f. felis (Bouche) off Nasua narica (koati), 

4 males, 8 females, San Luis Potosi, Dec. 19, 1955 ; off 
Syh'ilagus floridanns (cottontail), 2 females, Desierto de los 
Leones, Mexico City, Jan. 8, 1956. 

Kohlsia cora Traub out of mouse nest, 7 males, 12 females, 
Pueblo Nuevo, Chiapas, Feb. 11, 1956. 

Kohlsia whartoni T. and J. off Peromyscus bovlii (deer 
mouse), 2 pairs, Pueblo Nuevo, Chiapas, Feb. 6, 1956; off 
Neotoma mexicana (woodrat), 1 male, Pueblo Nuevo, Chia- 
pas, Feb. 9, 1956. 

Kohlsia linni new species 

There are before the writer at this time the holotype male, off 
Peromyscus boylii (deer mouse) (type host), Feb. 9, 1956; the 
allotype female and 2 male and 3 female paratypes off Neotoma 
mexicana (wood rat), Feb. 9, 1956; all taken at Pueblo Nuevo, 
Chiapas. 

The new species differs from others of the genus in the shape 
and armature of the 

Modified Segments : Male. Finger F, for the lack of better 
words to describe its shape, might be said to be bulbous or 
boxing glove like. The anterior border is slightly concave, and 
the complete apical border rounds nicely from its meeting with 
the anterior border to its junction with the process. On this 
face are three major bristles situated about equidistant along the 



lxi.\| ENTOMOLOGICAL NEWS 163 

upper three fourths of the border. A small bristle is located 
at the most apical point. The finger does not quite reach the 
apex of the process. The process P is squarish at its apical 
angle, the posterior face being almost perpendicular. The bris- 
tle at the lower corner of P is giant and very long, extending 
well beyond those on F. Sternite IX with lower apical angle 
squarish, the apical face bearing 4 short stout bristles, then with 
upper apical rounded and thumblike, and armed with 3 short, 
almost spiniforms. 

Female. Sternite VII with 2 lobes, the valley between larger 
or smaller, depending on variation, the upper lobe a small tri- 
angular protruberance, usually extending beyond the lower lobe 
which may be anywhere from rounded to block-like and squarish. 

This flea bears the name of Dr. Otto Linn, Dean Emeritus of 
Faculty, Pacific Bible College, Portland, Oregon, under whom 
the writer has now been teaching for ten years. 

Pleochaetis schmidti Traub off Neotoma mexicana (woodrat), 
1 pair, 1956, Pueblo Nuevo, Chiapas, Feb. 9, 1956. 

Pleochaetis mathesoni Traub off Neotoma mexicana, 1 male, 
Pueblo Nuevo, Chiapas, Feb. 9, 1956. 

Jellisonia irons! Eads off Baiomys musculns (pigmy mouse), 
1 female, Comitan, near Rio Grihalva, Chiapas, Feb. 15, 1956. 

Jellisonia grayi new species 

There are before the writer at this time, all from El Salto, 
San Luis Potosi, the holotype male, off Peromyscus boylii (deer 
mouse) (type host), Dec. 15, 1955, the allotype female and 2 
male and 1 female paratypcs with same data, and 1 male para- 
type off Peromyscus boylii, Dec. 18, 1955 ; and off Sigmodon 
hispidus (cotton rat), 1 male paratypc, Dec. 18, 1955. 

The new species differs from others in the genus in the shape 
and armature of the 

Modified Segments : Male. The finger F might be called 
triangular, the posterior face made undulant by the insertion of 
the 5 major bristles. The heel is well defined, and at this ven- 
tral apical angle there is inserted a very large bristle. Along 
the posterior border, about equally spaced, are 4 other promi- 



164 ENTOMOLOGICAL NEWS [June, 1958 

nent bristles which, due to their deep insertions, make the poste- 
rior border look undulant. Process P is somewhat hook shaped, 
the hook facing anteriorly. 

Female. Sternite VII consists of a squarish lobe below, then 
a deep valley, then a second lobe, pointed, triangular, and as 
long as the first. 

This flea bears the name of Dr. Albert Gray, President Emeri- 
tus of Pacific Bible College, Portland, Oregon. 

Foxella ignota chapmani new subspecies 

There is before the writer at this time only the holotype male 
which was taken off a cotton rat (Sigmodon hispidus) at El 
Salto, San Luis Potosi, on December 15, 1955. Although the 
holotype was taken off a cotton rat, it seems likely that this was 
accidental for Foxella usually have pocket gophers for their 
normal hosts. The new subspecies differs from others in the 
series mainly in the proportions of the VHIth sternite in the 
male. Due to the fact that this is short in the new subspecies 
it seems likely that it is close to Foxella ignota franciscana. 

Modified Segments : Male. Finger F long, slender and finger 
like ; armed along its posterior border with the usual equally 
spaced 3 major bristles. Process P, the characteristic long, 
slender, high process, armed at the apex by a few minute bristles. 
VII Ith sternite characteristic, the apex with the usual long, un- 
dulant bristle and above it a wide area, squarish, the area of 
which is greater than any Foxella ignota so far described. 

The female is unknown to the writer. 

This flea bears the name of Dr. Milo Chapman, President of 
Pacific Bible College, Portland, Oregon. 

Orchopeas howardi bolivari Barrera off Urocyon cinereoar- 

gcntcus (fox), 1 female, Pueblo Nuevo, Chiapas, Feb. 6, 1956; 

off Sciurns oureogaster (squirrel), 3 males, 1 female, Pueblo 

Nuevo, Chiapas, Feb. 5, 1956. 
Opisodasys robustus mexicanus Dampf off Sciurns nclsoni 

(squirrel), 2 males, 12 females, Desierto de los Leones, 

Mexico City, Jan. 1, 1956.

Pison (Paraceramius) koreense (Rad.), A New 

Adventive Wasp in Eastern United States 

(Hymenoptera, Sphecidae) 

By KARL V. KROMBEIN, Entomology Research Division, 
Agr. Res. Serv., U. S. D. A. 

For several years I have puzzled over the specific identity of 
a short series of Pison (5.5-6.5 mm. long), reared by A. D. 
Cushman, July 19, 1954, from some fragile clay cells. He 
found this aggregation of cells inside a discarded photographic 
tank stored under an old Army barracks. This building had 
been transported to McLean, Virginia, from Georgia after the 
war. More recently J. T. Medler sent a single specimen reared 
in 1957 from a similar cell found at Palisades Park, Illinois. 
At first I supposed that the wasp was Pison lacvc Smith, de- 
scribed from Georgia, but I. H. H. Yarrow at the British 
Museum advised me that Smith's species belongs to a different 
subgenus. Subsequent study of the collection in the U. S. 
National Museum indicated that this unknown species was 
more closely allied to those occurring in eastern Asia and the 
Orient than it was to any of the South American species. Sus- 
pecting by now that it might be koreense (Rad.), I borrowed a 
Japanese specimen of that species from K. Yasumatsu, and was 
able to confirm this tentative determination. 

P. koreense is native to Korea, China and Japan, and is now 
established at two localities in the United States. Presumably 
it was introduced here since the war, possibly on military mate- 
riel returned to this country (Palisades Park is near the Ord- 
nance Depot at Savannah, 111.). Probably it can be expected 



Lxix I ENTOMOLOGICAL NEWS 167 

to turn up at additional localities as it extends its range or as 
additional successful introductions are discovered. 

The reniform eyes covered with dense short hair and two 
submarginal cells will distinguish koreense from any of our 
native sphecoid wasps. It stores spiders in delicate clay cells 
about 8 mm. long and 4 mm. in diameter. The cells found by 
A. D. Cushman were constructed side by side in a diagonal row. 
The cocoon is opaque, rather brittle, cylindrical with rounded 
ends, and about 7 mm. long and 2.5 mm. in diameter. 

Radoszkowski (1887) included only koreense in his new 
genus Paraceramius. I do not accept Turner's synonymy 
(Proc. Zool. Soc. London, p. 617, 1916) of Paraceramius Rad. 
under Pison subgenus Pisonoides Sm. In the latter group the 
eyes are bare, the second recurrent vein is received well within 
the second submarginal cell (interstitial with the first transverse 
cubital vein in Paraceramius), and the mesopleuron is not mar- 
gined posteriorly by an oblique row of small foveolae. The 
other identified species before me belonging to the subgenus 
Paraceramius are the Philippine Pison browni (Ashm.) and 
P. different Turner from Java (type locality is Assam). Two 
unidentified Neotropical species also belong in Paraceramius, 
though probably in a separate species group because they have 
three submarginal cells.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

New Species and Notes on North American 
Acalyptrate Diptera 

By CURTIS W. SABROSKY, Entomology Research Division, 
Agricultural Research Service, U. S. Depart- 
ment of Agriculture 

Miscellaneous notes and descriptions in various families of 
North American acalyptrate Diptera are presented here for 
public record, to clarify misidentifications and synonymy. 

ANTHOMYZIDAE : Cyamops Melander 

The genus was reviewed by Sturtevant (1954, Proc. U. S. 
Nat. Mus. 103 : 557-559), who referred it to the Anthomyzidae, 
described one new species, and noted the considerable color 
variation in C. jicbulosa Melander. I take this occasion to note 
sexual dimorphism in color, and to describe a new species with 
entirely clear wings, undoubtedly confused in the past as a pale- 
winged variant of nebulosa. Sturtevant's key is modified 
slightly to include the new species. 

Ke\> to the Nearctic species of Cyamops 

1. Fore tibia and tarsus chiefly black; one pair of scutellar 

bristles C. imitata Sturt. 

Fore tibia and tarsus yellow, distal segment of latter infus- 
cated ; two pairs of scutellar bristles 2 

2. Wing typically heavily browned on disk and a narrow apical 

margin, in palest examples with only faint traces of brown 
along the veins and midway in marginal cell ; second van 
distinctly sinuate, suddenly narrowing the marginal cell 
about midway, where discal infuscation begins ; halter knob 
whitish yellow C. nebulosa Mel.

Wing membrane entirely clear; second vein almost straight,

Cyamops nebulosa Melander 

Cyamops nebulosa Melander, 1913, Jour. New York Ent. Soc. 
21: 292 (Mass.). 

The fortunate collecting of a good series of 33 specimens (18 
males, 15 females) at Cranberry Glades, Pocahontas County, 
W. Va., July 16, 1955, gave opportunity to check sexual di- 
morphism. In addition to the broader face mentioned by Sturte- 
vant, the females have the entire face and cheek black, palpi 
brown to black, and antennae infuscated on dorsal half. In the 
males, the face, anterior half of cheek, and palpus are bright 
yellow, and the antenna is predominantly so, only narrowly 
infuscated along the dorsal margin. 

Typically the pleuron in both sexes is pollinose, although 
thinly so and hence shining. In a few specimens, the greater 
part of the mesopleuron is bare and polished, a character that 
is often of specific importance. However, I can find no other 
differences, and for the present at least I regard this as a varia- 
tion. Three specimens of the 33 noted above, and five from 
scattered localities, are so marked. 

Cyamops halterata, n. sp. 

As described for C. nebulosa Melander, but differing in the 
characters noted in the key, and in having the palpi yellowish in 
both sexes, the central area of the front more deeply velvet black, 
and the orbital area flanking each antenna narrower and more 
conspicuously silvery than in nebulosa, and without a row of 
orbital hairs on its surface.

Available material seems to indicate that the new species is

MILICHIIDAE: Stomosis Melander 

This genus was proposed in 1913 for Desmometopa luteola 
Coquillett from Arizona, and that species was subsequently iden- 
tified from the wide range of Michigan, Indiana, Virginia, Texas, 
and Costa Rica. Recently the study of additional material and 
review of former identifications revealed that two species have 
been confused under the name luteola, and that the true luteola 
is a synonym of innominata (Will.). 

The genus will thus contain the following five known species : 
innominata (Will.), rufula (Frey) from Brazil, the new Ne- 
arctic species, and two species from Victoria, Australia, flaro- 
scutcllata Mali, and vittata Mali.

The correct family position of innominate, and its possible 
synonymy with Stomosis luteola (Coq.) were first suggested by 
H. Oldroyd of the British Museum (Nat. Hist.) in corre- 
spondence with Kenneth Frick regarding the identity of Willis- 
ton's Agromyza. Subsequently, Oldroyd kindly compared Costa 
Rican specimens of luteola with the type of innominata and 
found them to be the same. I have no material for clarifying 
the identity of the other Neotropical species, 5. rufula (Frey), 
described from southern Brazil, but it is many years junior to 
Williston's name and thus does not affect the recognition of 
the latter. 

In addition to the holotype of luteola, I have before me 34 
specimens of both sexes from the following localities : ARIZONA : 
Sedona, Oak Creek Canyon, June 29, 1953 (W. W. Wirth).

ton) ; 7, Almirante, Bocas del Toro, Jan. 1953 (Blanton) [all

I do not know the correct assignment of the Texas record of 
"luteola' cited by Melander (1913). The other records of 
luteola from eastern United States cited by Sabrosky (1953, 
Ent. News 64: 39) actually refer to S. flava, new species.

only slight differences, which might or might not prove reliable 
in a long series of specimens. 

The Maynardville, Tenn., series was reared from puparia 
found in a cavity near the base of a beech tree in a heavily 
shaded ravine. The cavity contained slightly moist woody ma- 
terial, and now and then a leaf or two. These rearings and that 
by Wirth at Fall Church suggest that this hitherto rather rare 
species should be looked for in tree hole debris.

NEW SYNONYMY. 

I have compared a Point Barrow specimen with the type of 
fiilriccps in the Museum at Stockholm. In Alaska, the species 
is apparently less common than arctica, judging from the avail- 
able material. I have seen a few specimens from Point Barrow,

Alaska, collected by Hurd and Sailer, and a lone specimen from 
Churchill, Manitoba, June 20, 1930 (O. Bryant) (det. Malloch 
as P. borealis). 

Neither julviceps nor arc tic a was included in Melander's 
review of the family in 1924 (Psyche 31 : 78-86), and Malloch's 
publication of borealis in 1919 was overlooked. Fortunately, 
this has not resulted in any synonymy of Melander's species. 
The two species are easily distinguished by color, in addition to 
a number of other characters. P. arctica has an entirely black 
head and body whereas julviceps has the front, outside of the 
upper orbits and ocellar triangle, and variably, the humeri, sides 
of mesonotum narrowly, and scutellum bright orange to reddish.

In 1948, I recorded this species from southern Georgia 
(Proc. Ent. Soc. Wash. 50: 85), apparently the first published 
record for North America. Subsequently A. R. Brooks, then 
at Ottawa, Canada, wrote me that he had seen a male of the 
species from Winnipeg, Manitoba, July 1942. Other specimens 
have since come to my attention from Grant and East Lansing, 
Mich, and Benton Co., Tenn. Recently several specimens were 
received from Irving Blake, collected in sweeping over alpine 
tundra at 13,100 ft. on Mt. Lincoln, Colo., Aug. 24, 1957. It 
now appears likely, especially from the last record, that the spe- 
cies is a normally Holarctic species long overlooked in North 
America. 

Males have a peculiarly distinctive wing, with the discal cell 
apically acute and a fringe of about a dozen long hairs on the 
margin of the wing about at the end of the fifth vein, but females 
could easily have been confused with other species of the sub- 
genus Coproica (Coprophila of Duda and Spuler). The females 
may be separated from other known North American species 
of this subgenus by the combination of second costal sectur

Three Species of Eurytoma Important in Biological 
Control of Weeds (Hymenoptera, Eurytomidae) 

By B. D. BURKS, Entomology Research Division, 
Agr. Res. Serv, U. S. D. A. 

This paper includes the descriptions of three species of the 
chalcidoid genus Eurytoma which are of actual or potential im- 
portance in projects for the biological control of noxious plants. 
The first species is a previously undescribed phytophagous one 
which develops in the seeds of the black sage (Cordia macro- 
stachya). It has been introduced from the West Indian island 
of Trinidad into the Indian Ocean island of Mauritius to aid 
in the control of this weed. The second species, Eurytoma 
cressoni Howard, is thought to be a parasite of the first; it is 
redescribed from fresh material. The third species is a pre- 
viously undescribed parasitic one which attacks the larva of a 
weevil, Microlarinus sp., which feeds commonly in the stems of 
the puncture vine (Tribulus terrestris} in South India. This 
weevil may prove to be useful in the control of this weed in the 
United States, but in India its effectiveness is considerably 
reduced by the attacks of the Eurytoma. 



Eurytoma attiva, new species 

Eur\toma sp., Williams, 1951, Mauritius Dept. Agr. Ann. Rpt. 
1949, no. 25, p. 64. 

This species agrees with howardi Dalla Torre ( mayri How- 
ard not Ashmead) in having weak facial striae which converge 
on the mouth opening ; in having a longitudinal fold crossing the 
lateral part of the pronotum; in having the prepectus smooth 
with the posterodorsal angle tonguelike; in having the propo- 
deum almost vertical, with a broad, median, shallow concavity; 
in that the petiole of the female is so short as scarcely to be 
visible ; and in having the fourth gastral tergite almost or quite 
as long as the preceding three tergites combined. The females 
of these two species differ in that the head in anterior aspect is 



178 ENTOMOLOGICAL NEWS u > 1958 



more square in attiva than in howardi; the antennal scape and 
midfemora are partly dark brown to black in attiva, although 
these structures are entirely yellow to tan in howardi; and the 
propodeal concavity is laterally shagreened in attiva, but it is 
rugulose in howardi. The males of attiva and howardi differ in 
that the antennal scape in attiva is clavate toward the apex, but 
it is not in howardi; the abdominal petiole is longer than the 
hind coxa in attiva, but it is slightly shorter than the hind coxa 
in howardi. 

Female. Length 2.5-3.0 mm. Black; antennal scape tan 
with more or less extensive dark brown to black shading api- 
cally; pedicel tan beneath and black above, flagellum dark 
brown ; mandibles, trochanters, bases and apices of femora, 
tibiae, and tarsi, tan ; wings hyaline, venation tan or yellow ; 
ventral base of gaster red-brown ; tips of ovipositor sheaths 
yellow. Pubescence relatively inconspicuous, silvery ; one or 
two pairs of obscure setae on each of basal three gastral tergites, 
fourth tergite with three pairs, fifth with one and a partial sec- 
ond irregular row of setae extending completely across tergite 
near its posterior margin, exposed surfaces of sixth and seventh 
tergites covered with long, slender setae. 

Frons in anterior aspect appearing to be almost square, indis- 
tinct striae converging on mouth; antennae inserted slightly be- 
low center of frons, apex of scape reaching level of vertex ; funi- 
cle segments becoming progressively slightly broader and shorter 
toward apex, so that fifth segment is li times as wide and f as 
long as first ; club as long as fourth and fifth funicle segments 
combined ; scrobe cavity with margins acarinate ; a faint and 
irregular carina encircling the compound eye; malar furrow 
present and complete ; postocellar line twice as long as ocel- 
locular. 

Umbilicate punctures of thoracic notum deep, distinct, inter- 
stices strongly shagreened ; pronotum with disc of lateral sector 
with a longitudinal fold ; prepectus smooth and shining dorsally, 
sculptured ventrally, its posterodorsal angle tonguelike ; tegula 
brown, smooth and shining ; anterior face of fore coxa excavated 
and flattened on apical two-thirds of its length; mesosternum 



Ixix] ENTOMOLOGICAL NEWS 179 

not prolonged anteriorly between bases of fore coxae ; forewing 
with marginal and postmarginal veins equal in length, stigmal 
vein as long as marginal, submarginal 5 times as long as mar- 
ginal; hind coxa with deep femoral concavity at apex, surface 
within this concavity smooth, rest of exposed surface of coxa 
with irregular, alveolate sculpture, this sculpture more minute 
on mesal surface than on outer surface. 

Propodeum vertical, with a broad, very shallow concavity on 
meson, this concavity with a median, vertical band of semi- 
transverse, strong rugae, area of concavity lateral to median 
band shagreened ; propodeal spiracles oval ; petiole short, much 
wider than long, and roughly sculptured; gaster 1^ times as 
long as thorax, first tergite entirely smooth and shining, second 
to fifth tergites smooth dorsally ; very faintly and minutely 
sculptured laterally near anterior margins ; fourth tergite the 
longest, being almost or quite as long as first 3 tergites com- 
bined ; sixth tergite, when seen in lateral aspect, forming a 50 
angle with longitudinal axis of gaster. 

Male. Length 2.0-3.0 mm. Antennal scape clavate toward 
apex ; funicle composed of 5 pedunculate segments, first slightly 
longer and thicker than any one of more distal segments ; club 
two-segmented ; petiole longer than hind coxa, ventral apex of 
petiole smooth, rest of its exposed surface with close, alveolate 
sculpture ; propodeum lacking the broad, shallow concavity of 
the female, a median, longitudinal groove present with areas 
lateral to it slightly produced and with rugose, irregular, alveo- 
late sculpture; gaster compressed, as long as thorax, third 
gastral tergite the longest.

The following species is thought to be a parasite of Eurytoma 
attiva, although it is possible that in part of its larval develop- 
ment its feeding is phytophagous rather than parasitic. As 
Noble (1940, Roy. Ent. Soc. London Trans. 90: 33) has shown, 
in some other species of Eurytoma the larvae spend part of their 
lives as parasites, passing the rest as plant feeders. E. cressoni 
was first segregated in material reared from Cordia seeds in the 
Island of Trinidad. Later it was found to have been introduced 
into the Island of Mauritius in Cordia seeds sent there from 
Trinidad. It was originally determined as an unknown species 
of Eurytoma by A. B. Gahan, formerly of the U. S. Department 
of Agriculture. Subsequently G. J. Kerrich, of the Common- 
wealth Institute of Entomology, London, was able to identify 
it as Eurytoma cressoni Howard by comparing specimens with 
the female type of that species in the British Museum (Natural 
History) collection. Mr. Kerrich has very kindly checked my 
redescription against this type.

to each antennal socket, hind coxae may be partly or almost 
entirely yellow or tan, and light color may extend from venter 
onto lateral areas of fourth and fifth gastral tergites or, some- 
times, extend over entire surface of fourth gastral tergite ; wings 
hyaline with venation yellow to tan. Pubescence fine, silvery; 
dense on metepisternum and sixth and seventh gastral tergites. 

Antennae inserted slightly below center of frons, apices of

ments equal in width, and gradually decreasing in length, the 
first somewhat longer than the fifth ; club as long as first and 
second funicle segments combined; scrobe cavity with lateral 
and dorsal margins obscurely carinate ; face with numerous, 
strong striae converging on mouth opening ; compound eye not 
encircled by a carina ; malar furrow complete ; postocellar line 
2\ times as long as ocellocular. 

Umbilicate punctures of thoracic notum deep, regular, and 
closely set, interstices very narrow, shagreened ; anterior face of 
fore coxa flattened and slightly excavated from base to apex; 
mesosternum not produced anteriorly between fore coxae; pre- 
pectus smooth dorsally, sculptured ventrally, its posterodorsal 
angle bluntly rounded ; tegula smooth, shining ; forewing with 
marginal vein twice as long as stigmal and 1-J- times as long as 
postmarginal, submarginal vein 3o times as long as marginal; 
hind coxa with a shallow femoral cavity at apex, surface within 
this concavity slightly sculptured, almost smooth, rest of exposed 
surface of coxa with uniform alveolate sculpture. 

Propodeum vertical, median area of propodeum with a shal- 
low and broad concavity, surface of this concavity shagreened 
and irregularly rugulose, lacking a median, longitudinal band of 
rugose sculpture ; petiole so short as scarcely to be visible in 
undissected specimens ; gaster slightly compressed, varying from 
1; 1 ( to 1| times as long as thorax; fourth gastral tergite as long 
as basal 3 tergites combined ; first gastral tergite smooth, second 
and third smooth on dorsomedian line and at posterior margins, 
otherwise with minute, closely set, irregularly alveolate sculp- 
ture; fourth tergite completely sculptured except for a pair of 
lateral sub-basal smooth spots; fifth tergite more minutely sculp-

tured than fourth ; apex of abdomen acuminate, ovipositor and 
seventh gastral tergite directed obliquely dorsad, ovipositor 
sheaths slightly exserted. 

Male. Length, 1.52.0 mm. Color as in female except that 
light color is less extensive on hind coxae and gaster, and hind 
tibiae are usually mostly black ; antennal scape broadened in 
basal f, constricted apically; funicle with 4 pedunculated seg- 
ments ; club three-segmented ; propodeum with median concavity 
deeper and narrower than in female; petiole as long as or 
slightly longer than hind coxa ; gaster not compressed, f as long 
as thorax; third gastral tergite the longest. 

Type locality. Balthazar, Grenada, B. W. I. 

Lectotype. Female, in the British Museum (Natural His- 
tory). 

This species was originally described from a female and male 
cotypes. The male cannot now be found either in the British 
Museum (Natural History) or the U. S. National Museum 
collections, so it is presumed to be lost. The female specimen is 
hereby designated as the lectotype, and Mr. Kerrich has so 
labeled it. 

Enrytoma cressoni is redescribed from specimens from St. 
Augustine, Toco, and Nariva, Trinidad and from Mauritius, 
reared either from the seeds or from the inflorescence of Cordia 
macrostachya. These specimens are divided between the British 
Museum (Natural History) and the U. S. National Museum

The name of the following species has long since gotten into 
the literature, but no description of it has ever been found. 
Girault's manuscript types of it have been in the U. S. National 
Museum collection since 1916. T. V. Ramakrishna Ayyar in 
1920, in discussing parasites of Alcidodes bubo (F.) in South 
India, said of it : "Two parasites, Metastenomyia jitliani Gir., 
and Eurytoma pigra Gir., have been noted on the grub ; but not 
to any great extent." On an accompanying plate he figures a 
"Chalcidid parasite" of Alcidodes bubo, without naming it fur-

ther. The specimen figured is clearly a pteromalid (probably 
Metastenomyia), so that this publication could not be taken to 
have validated the name Enrytoma pigra.

This species may be distinguished from other oriental species 
of Eurytoma as follows : It differs from poloni Girault in lacking 
a pair of sublateral, longitudinal carinae on the first gastral ter- 
gite ; it lacks the conspicuously long and stout setae which are 
borne on the posterior margin of the hind tibia in setitibia 
Gahan ; the female abdominal petiole is short, not as long as 
or longer than the hind coxa, as in brunneipennis Crawford; 
the face has striae converging on the mouth opening, not with 
unmodified umbilicate punctation as in albotibialis Ashmead, 
although both pigra and albotibialis have low carinae on the 
frons running parallel with and close to the anterior margins of 
the compound eyes ; in kindupurensis Gahan the mesosternum 
is prolonged anteriorly as an acute projection between the an- 
terior coxae, although this projection is truncate apically in 
pigra. Other oriental species, such as systoloides Crawford and 
manilcnsis Ashmead, have convergent facial striae, but they lack 
the low carinae bordering the compound eyes. The anterior 
coxa has a distinct toothlike projection near the middle of the 
outer ventral margin in nesiotcs Crawford, but this projection 
is wanting in pigra. In both pigra and nesiotes the propodeum 
has a very broad, shallowly concave median depression. 

Female. Length 2.5-3.0 mm. Black; antennae, trochanters, 
bases of fore and mid femora, all but bases and apices of mid 
tibiae, and sometimes base of gaster, dark brown ; apices of all 



184 ENTOMOLOGICAL NEWS u* 1958 



femora, bases and apices of mid and hind tibiae, and mid and 
hind tarsi, yellow ; front tibiae and tarsi tan ; wings hyaline with 
venation yellow. Pubescence of head, body, and appendages 
short, silvery; gastral tergites 1-3 bare, fourth tergite with a 
few setae laterally, tergites 5-7 densely setose. 

Antennae inserted in center of frons, apices of scapes reaching 
level of anterior ocellus ; funicle segments all subequal in length 
and width, fifth segment only very slightly shorter and broader 
than first, club as long as funicle segments 4 and 5 combined ; 
scrobe cavity carinately margined laterally and dorsally ; face 
with strong striae converging on mouth opening ; weak but dis- 
tinct carinae encircling compound eyes, these carinae bordering 
the frons laterally; malar furrow obsolete; postocellar line 3 
times as long as ocellocular. 

Umbilicate punctures on thoracic notum shallow, interstices 
narrow, somewhat irregular, lightly shagreened ; prepectus 
smooth, shining, its posterodorsal angle blunt; anterior face of 
fore coxa excavated from base to apex ; mesosternum produced 
forward between bases of anterior coxae, its apex truncate, and 
a short, median, longitudinal carina present ; tegulae black, 
lightly sculptured, almost smooth ; forewing with marginal and 
stigmal veins equal in length, postmarginal 1^ times as long as 
marginal, submarginal 4 times as long as postmarginal ; hind 
coxae with minute, alveolar sculpture extending completely over 
exposed surfaces, a deep, concave femoral groove present at 
apex. 

Propodeum almost vertical, lying at an angle of 80 with 
longitudinal axis of thorax ; median area of propodeum broadly 
and shallowly concave ; surface of concavity shagreened and with 
a median longitudinal band of confused, semi-transverse rugulae, 
these varying in intensity in different specimens ; propodeal spi- 
racles elongate-ovate ; petiole extremely short, but discernible ; 
gaster varying from lyo to 1^ times as long as thorax, first 
gastral tergite smooth, tergites 2-4 minutely and closely pitted 
laterally and anteriorly on dorsum ; fourth tergite the longest, 
being twice as long on dorso-meson as third tergite and as long 
as first and second combined; gaster acuminate at apex, dorsal

surface of sixth tergite, when seen in lateral aspect, forming a 
55 angle with longitudinal axis of gaster. 

Male. Length 2.5 mm. Antennal funicle composed of 5 
pedunculate segments, first segment slightly longer than any of 
those following ; club two-segmented ; femoral groove at apex of 
hind coxa more shallow than in female ; petiole longer than hind 
coxa, apex of petiole smooth, rest of its surface with minute, 
alveolar sculpture ; gaster compressed and as long as thorax, 
third gastral tergite the longest, fourth tergite extremely short.

A New Species of Conosphaeron Linsley from 
Arizona (Coleoptera: Cerambycidae) 

By JOSEF N. KNULL, Department of Zoology and Entomology, 
The Ohio State University, Columbus 10, Ohio 

This interesting specimen appears to belong to genus Cono- 
sphaeron Linsley (1935). 

Conosphaeron pullum n. sp. 

Female : Dark brown throughout, shining on both surfaces. 
Head coarsely densely punctured, sparsely clothed with long 
hairs; eyes coarsely granulated; antennae extending beyond 



186 ENTOMOLOGICAL NEWS [July, 1958 

apex of elytra when laid over top, third and following segments 
flattened, carinate, ciliate to ninth segment, three to seven in- 
clusive spinose at tip, scape stout, coarsely punctured. Ratio 
of lengths of segments 1 to 10, 4:1:6:4.4:4.8:4.4:4.6:4.2:3.7: 
3.2, last segment missing. 

Pronotum slightly longer than wide, widest back of middle, 
apex and base about same width ; sides rounded with obtuse 
tubercle back of middle which gives it an angled appearance; 
surface convex with an elongate smooth area in middle and an 
oblique one each side near base ; a transverse lateral depression 
each side at base; irregularly, densely, coarsely punctured; 
sparsely clothed with long ciliate hairs. Scutellum densely 
clothed with short recumbent pubescence. 

Elytra at base wider than widest part of pronotum, widest 
near base ; sides converging toward apex, broadly rounded near 
apex, apex emarginately truncate ; surface densely coarsely 
punctured, punctures diminishing in size toward apices ; densely 
clothed with long recumbent pubescence, sparsely intermixed 
with long ciliate hairs. 

Beneath abdomen sparsely, finely punctate, pubescence sparse, 
long ; prosternum transversely rugose ; femora coarsely punc- 
tured toward apices ; all tibiae carinate. 

Length 12.6 mm.; width 2.9 mm. Holotype $ collected at 
light five miles north of Nogales, ARIZONA, July 30, 1957, by 

D. J. and J. N. Knull, in collection of author. 

This species appears to be close to Conosphaeron piceum Lins. 
(1935). 

The elytra are considerably wider than pronotum ; the long 
ciliate hairs of elytra are shorter toward apices instead of longer 
as in pic cm n. 

I am indebted to G. B. Vogt for comparing it with specimens 
in the U. S. National Museum.

Some Species of the Genus Bathypogon Loew 

By FRANK M. HULL, University, Mississippi 

Flies of small or medium size which belong to the subfamily 
Dasypogoninae and are characteristic of the Chilean and Aus- 
tralian regions. A number of undescribed species have recently 
been found in collections and several are described in this paper. 

Bathypogon ichthyurus, new species 

A small species with wholly black color, except some red on 
the terminalia and the very dark reddish brown humerus. Fur- 
ther characterized by the 4 pairs of scutellar bristles and the 
curious, fish-tailed process curving down to the apex of the 
superior forceps. Length 12 mm. 

Male. Head: The head is black in ground color, the vertex 
and front are wider than usual, the occipital pollen grey, the 
pollen of front and vertex quite thin, simewhat brownish across 
the upper front and vertex and yellowish grey on the lower half 
of the front, except for a narrow border along the eye margin, 
which is longer, denser and brownish yellow. Face a little 
wider, more produced and protuberant, the elevation occupying 
the lower two-thirds ; the pubescence is greyish white with a 
yellow cast and the eye margins laterally have thick yellow 
pubescence cintinued fro mthe front but not extending on the 
lower face or cheeks. Bristles of face unusually numerous but 
not very stout. Palpus and proboscis black. All pile and 
bristles of the head pale brownish yellow, except those of the 
ocellarium and the short bristles on the upper occiput, which 
are light brown. Antenna black, except the base of third seg- 
ment and apex of the second segment, which are sepia brown. 
Third segment slender, only slightly dilated, the style a little 
longer than usual. 

Thora.r: The thorax is everywhere quite black, except on the 
humerus, which is quite dark reddish brown. Pollen over the 
mesonotum, including the lateral margin before the suture, dark 
brown with a distinct reddish cast, but behind the suture some- 



188 ENTOMOLOGICAL NEWS [July, 1958 

what greyish yellow. Though badly preserved, there are evi- 
dences of 2 submedial, black stripes separated by 3 narrow 
vittae of pale brownish yellow pollen, which might possibly be 
described as greyish yellow. The complement of thoracic bris- 
tles consists of 1 posthumeral, 2 notopleural, 1 supraalar, 2 
postalar and 4 pairs of strong scutellar bristles. Metapleural 
bristles not strongly differentiated. The pollen on the black 
pleuron is reddish to yellowish brown and appears to be rather 
thin over much of the pleuron. 

Legs: The legs are black, except the dorsal surface of the 
anterior and middle tibiae, which is quite dark reddish brown 
and a little lighter on the basal half. Tarsi brownish black. 
All pile and bristles of legs pale brownish yellow. Claws rather 
slender, brown on the basal third. 

Wings: The wings are nearly hyaline with dark brown veins. 
The lower end vein of the discal cell makes a strong angle with 
the lower end vein of the fourth posterior cell. There is a 
minute stump of a vein a short distance from the base of the 
anterior branch of the third vein. 

Abdomen: The abdomen is black with only the terminalia 
dark reddish to reddish brown. Pollen of abdomen distinctly 
grey on the dorsal portion of the tergites, where it forms a large 
posterior triangle, which in some lights appears to be divided 
medially. The lateral pollen on the first 4 tergites is more or 
less dark reddish brown, lighter in color on the remaining ter- 
gites. The superior forceps are drawn down into an extended, 
sharply pointed, fish-tail process on each side, thus each half 
has 2 points with a deep concavity between. The process of 
the outer point is longer than the medial point. The hypan- 
drium has a prominent, thin, rounded, scoop-like processes. 

Type. Male, L. Callabonna, collected by A. Zietz. No date 
given. Type in the South Australian Museum. 

Bathypogon nigrotibiatus, new species 

A moderately large species characterized by the general black 
ground color, the black femora and tibiae ; the femora have only 
narrow, dark reddish brown stripes posteriorly. The thoracic 



Ixix] ENTOMOLOGICAL NEWS 189 

bristles are pale brown, the scutellar and facial bristles quite 
pale brownish yellow. Antenna black. A species with very 
distinct terminalia. The lower apex of the superior forceps 
has a curious, strong but slender, curved, pointed process ; the 
hypandrium has stout, curved and excavated protuberances. 
Length 20 mm. 

Male. Head: The ground color of the head is entirely black, 
the pollen quite pale greyish yellow, the pubescence of the same 
color. The stout bristles of the face are extremely pale brown- 
ish yellow. First 2 antennal segments are totally black; third 
missing. Palpus black, but pollinose and not shining, its pile 
and the lower occipital pile brownish white. Postvertical bris- 
tles quite pale. 

Thorax: The thorax everywhere is black in ground color, the 
pollen dark brown widely over the middle and pale brownish 
yellow r laterally. The extreme posterior corner of the humerus 
laterally has a tiny reddish bro\vn spot. The stripes are very 
poorly differentiated from either anterior or dorsal view. Along 
the medial margin of the humerus the pollen is a little lighter 
and more nearly golden brown. The thoracic complement of 
bristles, all of them light brown, consist of 1 posthumeral, 2 
notopleural, 1 supraalar, 2 scutellar pairs and 3 postdorsocentral 
elements. The pleural pollen is similar to that on the sides of 
the mesonotum. 

Legs: The legs are everywhere black, except for an indistinct, 
posterodorsal, reddish brown stripe on the anterior and middle 
femora. Pile and bristles are pale brownish yellow. Claws 
stout, slightly more blunt than usual and more than the basal 
third is light brown. 

Wings: The wings are nearly hyaline and dilutely tinged with 
pale brown, veins dark brown and at the extreme base light 
reddish brown. The lower end vein of the discal cell and the 
end vein of the first posterior cell are quite aligned. 

Abdomen: The abdomen is blackish sepia in color, the lateral 
margins with dense, bright, golden brown pollen and the dorsal 
portion with thin, dark brown pollen. Pile and bristles pale. 
On the outer third the posterior margins of tergites 2 to 4 are 



190 ENTOMOLOGICAL NEWS [July, 1958 

contrastingly colored, and to some extent this is true of the 
fifth tergite. These margins are pale brownish yellow with 
similar pollen. The terminalia are entirely blackish, except for 
the slender, ventroapical process on the superior forceps, which 
is red and the hypandrium which is a pale mahogany red ventro- 
medially and again on its apical and lateral half. The ventral 
process from the hypandrium is darker. This process is quite 
characteristic and takes the form of a stout, curved, ventral, 
apically truncate and laterally excavated protuberance. 

Type. Male, Cairns District, collected by F. P. Dodd. No 
date given. Type in South Australian Museum. 

Bathypogon microdonturus, new species 

A small, light reddish species with dark brown thorax. The 
head is black in ground color and all bristles are light yellowish 
brown. The hypandrium has only very small, short teeth. 
Length 13 mm. 

Male. Head: The pollen of occiput and front and the pu- 
bescence of the face light brownish yellow or ochre colored. 
The bristles are similar, except those of the face, which are 
more yellowish. Antenna absent. 

Thorax: The thorax is quite dark brown in ground color, 
including the humerus. Only the coxae are more reddish. The 
pollen of the mesonotum is a dark, golden brown, but anteriorly 
between the humeri it is a lighter and faintly reddish golden 
brown. Humeral, lateral, marginal and the whole pleural pol- 
len is thick, pale, brownish to golden yellow. The thoracic 
complement of bristles consists of 1 posthumeral, 2 notopleural, 
1 supraalar which may be lacking, 2 postalar, 2 scutellar pairs, 
4 postdorsocentral and 4 weakly differentiated, metapleural 
bristles, besides the usual complement of stiff, long, metapleural 
hairs. 

Legs: The femora are moderately stout and are light reddish 
brown to orange brown with the anterior surface of the anterior 
and middle pairs and the posterior surface of the hind pair dark 
sepia brown. The tibiae are light reddish brown with the 
anterior surface and lateral surface of the hind pair obscurely 



Ixix] ENTOMOLOGICAL NEWS 191 

darker. All tarsi light brownish red. Claws sharp, slender, 
with the basal third quite red. Pile and bristles of legs quite 
pale brown. 

Wings: The wings are nearly hyaline and dilutely tinged 
with pale brown. Veins reddish brown, the apical fourth is 
darker and villose ; the lower end vein of the discal cell makes 
quite a strong angle with the end vein of the fourth posterior 
cell, this being one of the strongest angles that we have seen. 

Abdomen: The abdomen is reddish brown, darker on the 
dorsal portion and lighter along the lateral margins, the pollen 
rather uniformly pale reddish to yellowish brown. Terminalia 
chiefly reddish brown, rather dark except narrowly along the 
medial border of the superior forceps. Hypandrium with short, 
lappet-like processes. 

Type. Male. Owieandana, North Flinders Range, collected 
by Hale and Tindale. Type in the South Australian Museum. 



On the Bee Genus Cyphomelissa (Hymen., Apoidea) 

By J. S. MOURE, C.M.F., 1 Department of Entomology, Univer- 
sity of Kansas, Lawrence, Kansas, and Secgao de 
Zoologia, Universidade do Parana, Curitiba, Brasil 

The genus Cyphomelissa Schrottky (1902) contains large 
robust, parasitic bees found in South America. The conspicuous 
differences between this genus and similar ones are indicated by 
Moure (1946, Notas sobre as mamangabas, Boletim Agricola, 
4: 21-50). The following account contains descriptions of two 
new forms and a key to known species. 

1 I wish to thank the Rockefeller Foundation (New York), the Na- 
tional Science Foundation (Washington) and the Campanha de Aperfeigo- 
amento de Pessoal de Nivel Superior (Rio de Janeiro) for aid that made 
this study possible. Also, I wish to thank Dr. Carlos Alberto Campos 
Seabra of Rio de Janeiro for the stimulus and generosity which he is 
giving to studies of Brasilian bees, and Dr. Charles D. Michener of the 
University of Kansas for help in preparation of this paper.

A Change of Name in the Bombyliid Genus 
Anastoechus (Diptera). 

By JACK C. HALL, University of California, Riverside, California 

In ENTOMOLOGICAL NEWS, 67(8) : 199, 1956, I proposed the 
name Anastoechus deserticola for a new species. Since that 
time I have received word from Dr. A. J. Hesse of the South 
African Museum, Capetown, South Africa, that the name had 
been used by him in 1938, Ann. S. African Mus., 34: 347, for 
a South African species of Anastoechus. His species was 
named deserticolus. Since the names are of the same formation 
and since his name has priority I propose the name Anastoechus 
hessei for my A. deserticola, in honor of Dr. Hesse.

THE NEOTROPICAL SPECIES OF THE 
'SUBGENUS AESCHNA' SENSU SELYSII 1883 

(Odonata) 

By Philip P. Calvert 

This paper presents an account of the Neotropical species referred 
by de Selys in 1883 to his subgenus Aeschna and of some species un- 
known to him. His subgenus is here divided into three genera, 
Aeschna, Coryphaeschna, and Castoraeschna, Aeshna in its turn be- 
ing subdivided into the subgenera Aeschna, Hesperaeschna, Rhio- 
naeschna, Schizuraeschna, Marmaraeschna and Neureclipa. These 
five subgenera include 2, 15, 1, 3, 4 and 5 species and subspecies 
respectively. Coryphaeschna embraces 9 species and subspecies, 
Castoraeschna 5. Larvae of 2 species of Hesperaeschna, 1 species of 
Schizuraeschna, 1 species of Neureclipa and 6 species of Cory- 
phaeschna are described and figured. Generalities are discussed under 
the headings : Relationships of the Neotropical Aeshnas to the North 
American fossils ; Relations of the South American Aeshnas to the 
Palaearctic and Australian species ; The geological age and geographi- 
cal distribution of the ancestors of the Odonata and of the Mammalia ; 
Relations of the Neotropical Aeshnas to each other; The seasonal 
distribution of the Neotropical species of Aeshna. Forty plates in 
black and white illustrate the structural and colorational features of 
the adults, seven those of the larvae. Nineteen tables show the varia- 
tions in size and in venation of the adults. Six maps show the geo- 
graphic distribution of all the species concerned. There is an alpha- 
betical index of species, subgenera, genera, authors quoted, and topics.

Observations on the Nesting Behavior of Larropsis 
distincta (Smith) (Hymenoptera, Sphecidae) 

By HOWARD E. EVANS, Cornell University, Ithaca, N. Y. 

Very little has been recorded on the nesting behavior of digger 
wasps of the genus Larropsis. Williams (1913, Kansas Univ. 
Sci. Bull., 8: 192) found L. divisa (Patton) preying upon cave 
crickets (Ceuthophilus) in Kansas. Williams found two nests 
of this species, one in the bottom of a crack in the earth, the 
other inside a hole "the size of that made by a mouse." He 
was unable to dig either nest successfully, but believed that the 
nest was fairly deep and of several cells. Williams noted that 
wasps of this genus occur frequently about holes dug by mam- 
mals ; he believed that they seek cave crickets in these places. 

During the summer of 1957, I found an unusually large popu- 
lation of Larropsis distincta (Smith) inhabiting a gravel pit near 
Six-mile Creek, Ithaca, N. Y. On every sunny day many 
females could be seen hunting prey, and on several occasions 
females were seen carrying prey to their nests. Nine nests were 
eventually marked and dug out. The first observations were 
made on August 26, the last on September 18. All the Ithaca 
specimens in the Cornell collections were taken between August 
9 and September 18. It seems certain that this species has but 
a single generation a year in the Northeast. 

Hunting is done among stones, dried leaves, and low vegeta- 
tion. The wasps walk along the ground in a circuitous path, 
entering depressions and accumulations of debris. Any crickets 
which are flushed are pursued rapidly, but I did not observe 
capture and stinging. Some of the crickets flushed may be un- 
acceptable to the wasps, as all of the numerous crickets which

198 ENTOMOLOGICAL NEWS [Oct., 1958 

I took from wasps or from nests were adult female Neinobius 
fasciatus (DeGeer) [det. A. B. Gurney]. There are also two 
specimens in the Cornell collection taken at Ithaca by P. P. 
Babiy with females of this same species of cricket. 

After being stung, the crickets are carried to the nest over 
the ground, the wasp seizing the base of the antennae with its 
mandibles and proceeding forward, straddling the cricket's body, 
which is dorsum-up. Occasionally the wasp may make a short 
flying hop or carry the cricket up a plant 10-20 cm. and then 
fly off heavily with it. The latter behavior occurs most com- 
monly near the nest, and may enable the wasp to obtain a better 
view of the vicinity of the nest. In the area of study, all nests 
were situated in relatively bare places in the gravel pit, and it 
was a common sight to see wasps proceeding over the ground 
with their prey in a more or less straight line from the litter 
and low vegetation of surrounding areas into the nesting area. 
Once in the nesting area, they would circle about and eventually 
disappear rather suddenly into a hole in the ground. 

Without exception, the wasps in this aggregation made their 
nests from the bottoms of pre-existing depressions in the ground. 
These depressions were often beneath sticks or dried leaves and 
in most cases appeared to represent caved-in parts of the bur- 
rows of the hairy-tailed mole, Parascalops brezveri (Bachman). 
The burrows of the wasps, emanating as they did from the 
bottoms of these depressions and associated mole tunnels, were 
exceedingly difficult to trace, and only five of the nine nests 
marked were dug out with any degree of success. Apparently 
the wasps take advantage of various natural cavities among the 
clods and pebbles and do not do very much digging themselves. 
The cells found varied in depth from 10 to 20 cm., with the 
majority between 12 and 15 cm. In any one nest the cells 
tended to radiate out from a common point. Of the five nests 
dug out successfully, one contained only one cell, one contained 
two, one three, one seven, and one nine. Doubtless the nests 
with only a few cells would have eventually contained more. In 
fact, it is probable that once a wasp has found a suitable hole 
in the soil it continues to construct cells from the same cavity 
for as long as it lives. 



Ixix] ENTOMOLOGICAL NEWS 199 

The cells are rough-walled and somewhat irregular, generally 
measuring about 1.5 cm. in length. The usual number of 
crickets per cell is two, but I found a few cells with three and 
a few with apparently only one cricket. As mentioned above, 
all crickets were adult female Nemobius fasdatus. The egg is 
laid on the first cricket placed in the cell. It is about 2 mm. 
long and is placed transversely between the front and middle 
coxae, with one end pressed against one of the front coxal cavi- 
ties. The egg hatches in two days and the larva begins to feed 
through the coxal cavity. As it grows, the larva bends itself 
around the prothorax of the cricket, like a collar, as it continues 
to feed through the venter of the thorax. In about three days 
it consumes the first cricket and then proceeds to consume the 
remaining one or two crickets more rapidly, finishing the entire 
contents of the cell about five days after hatching. I have de- 
scribed the full-grown larva elsewhere (1958, Trans. Amer. Ent. 
Soc. 84: 119-120). 

The crickets are paralyzed rather lightly, and until consumed 
by the wasp larva they often show spontaneous movements of 
legs and antennae, but are unable to walk about in a co-ordinated 
manner. The contents of several cells appeared to have been 
destroyed by mold. 

Of 23 cells dug out, no less than 13 contained the maggots of 
miltogrammine flies. The number of maggots per cell varied 
from one to six, w r ith the usual number three or four. Without 
exception the wasp larva failed to develop in these cells. On 
more than one occasion an intact egg on its cricket was removed 
from a cell for rearing only to have it destroyed by minute, 
first-instar maggots within a day or two. Apparently these 
maggots are deposited beneath the wings or in some other con- 
cealed place; later they move onto the egg and destroy it, then 
consume the crickets and form their puparia in or near the cell. 

None of the flies was actually observed larvipositing in the 
field. The maggots taken from various cells were placed in 
rearing tins, overwintered outdoors, and brought into the lab- 
oratory in March 1958. Emergence of flies was obtained from 
all five nests. Of 25 flies reared, 14 were Mctopia arcjyroccphala 
(Meigen) and 11 were Scnotainia trilincata (\Yulp) | det. 



200 ENTOMOLOGICAL NEWS [Oct., 1958 

W. L. Downes, Jr.]. In one case both species emerged from 
the same nest (no. 1494; 7 Metopia and 1 Senotainia}. How- 
ever, three cells of this nest had been infested, and I placed all 
three cells in the same rearing tin. Thus I cannot say whether 
or not the two species of miltogrammines infested the same cell. 
The rather local distribution of wasps of the genus Larropsis 
may be a result of the fact that they require coarse soil con- 
taining various natural cavities. It may be that they are at- 
tracted to animal burrows more for purposes of nesting than 
for finding crickets, as Williams suggested. I would judge these 
wasps to be among the most primitive of Sphecidae in their 
nesting behavior. At least the practice of using pre-existing 
cavities in the soil, the light paralysis of the prey, and the man- 
ner of carrying the prey over the ground with the mandibles 
are all usually regarded as primitive traits. A great many more 
Sphecidae must be studied in detail before one can confidently 
generalize regarding the evolution of behavioral characters. 



Teratobates Esaki, a Synonym of Heterobates 
Bianchi (Gerridae, Heteroptera) 1 

By HERBERT B. HUNGERFORD and RYUICHI MATSUDA, 
Department of Entomology, University of Kansas 

In 1896 V. Bianchi described Heterobates for his H. doli- 
randti (Ann. Mus. Zool. Acad. Sci. St. Petersbourg, 74). We 
have in our University of Kansas Collections three males and 
two females of this species kindly sent by Dr. A. N. Kiritschenko 
many years ago. In our study of the genera and higher cate- 
gories of the Gerridae we were able to borrow from Dr. W. E. 
China of the British Museum paratype specimens of Teratobates 
bilobatus Esaki. Dr. Esaki described this species in 1927 (Eos,

similar in appearance and we are impressed by the remarkable 
modification of the thoracic and abdominal venters of the females 
in both the species (figs. 1 and 2). They are plainly different 
species but must be congeneric.

New Locality Records for Proisotoma frisoni, 
(Collembola, Isotominae) 

By HAROLD GEORGE SCOTT, Communicable Disease Center, 

Public Health Service, U. S. Department of Health, 

Education, and Welfare, Atlanta, Georgia 

Proisitoma frisoni Folsom can be distinguished from other 
members of the genus by means of the following diagnostic char- 
acteristics : white, eyes absent ; postantennal organ elliptical ; 
antenna longer than head ; Abd V and VI not fused ; ratio of 
Abd III to IV as 5:6; unguis without teeth; hind unguiculus 
two-thirds as long as hind unguis, one-half as long on other 
legs ; one tenent hair ; furcula present, extending to posterior 
part of Abd II; length 1.1 mm. 

This species was described by Justus Watson Folsom (1937) 
from Cahokia, Illinois. Since then no records of the species 
have been published. Two additional records are noted as 
follows : 

1. Taken by C. Clayton Hoff from Berlese funnel sample of 
mixed aspen-fir litter, 9,700 feet, along Canjilon Road, at divide 
west of Vallecitos, Rio Arriba County, NEW MEXICO, 13 Aug. 
1953 (included in a dissertation presented to the University of 
New Mexico in partial fulfillment of the requirements for the 
Degree of Doctor of Philosophy, aided by National Science 
Foundation Grant G-112). 

2. Taken by Jerrold M. Michael from around potted Ficus 
elastica in a private home, Decatur, DeKalb County, GEORGIA, 
21 March 1958. The infestation was eliminated by dusting the 
plants with 2/o chlordane. Since overwatering of potted plants 
is often a key factor in the development of household infesta- 
tions of Collembola, it was recommended that, henceforth, the 
plants be watered only after the soil appeared dry.

Notes on the Bionomics of the Mantispidae 
(Neuroptera: Planipennia) 

By SOPHY PARFIN, United States National Museum, 
Washington, D. C. 

Because information on the hypermetamorphic Mantispidae is 
scarce, it is believed that the following three notes on their bio- 
nomics will be of interest. All of the specimens, on which these 
observations are based, are in the collection of the United 
States National Museum. 

I am grateful to the late J. C. Bridwell (Lignum, Virginia) 
and G. B. Vogt (Entomology Research Division, U. S. Depart- 
ment of Agriculture) for making certain mantispid specimens 
available for study; to W. J. Gertsch (American Museum Nat- 
ural History) for the identification of a spider egg-sac; to J. F. 
Gates Clarke (Smithsonian Institution) for helpful suggestions 
in the preparation of the manuscript; to R. E. Crabill (same 
institution) for providing the approved names of the spiders; 
to K. V. Krombein (Entomology Research Division, U. S. 
Department of Agriculture) for supplying the current names 
of the vespid wasps ; and to C. W. Sabrosky and W. W. Wirth 
(same Division ) for the determination of the sarcophagid. 

MANTISPID HOSTS 

Three cocoons of the green mantispid, Mantis pa viridis Walker 
(tentatively determined until a revision of the Mantispidae is 
completed ; in the genus Mantispilla, according to Enderlein's 
key, 1910, pp. 341-349), in two similar spider egg-sacs, were 
collected by the late J. C. Bridwell in "late 1951," at Lignum, 
Virginia, on the underside of a plank buried in grass. The 
adults emerged "early in 1952," according to Mr. Bridwell. 
One of the egg-sac halves, containing one cocoon, was sent to 
Dr. W. J. Gertsch, who kindly identified it as the sac of a 
spider, Agelcnopsis sp., prob. pennsyh'ctnica Koch, a familiar 
grass spider in the area. The cocoons, which are approximately 
9 mm. long and 7 mm. wide, are composed of a dense, thick. 
white outer portion (about 1 nun. thick), and a niurli thinner

and considerably more loosely woven, pale yellow inner lining. 
The two light gray spider egg-sacs are each about 1.8 cm. in 
diameter. It was interesting to note that two mantispid larvae 
were able to complete their development in one spider egg-sac, 
without one destroying the other.

LONGEVITY IN THE MANTISPIDAE 

A female of Mantispa viridis was kept alive by the writer for 
a period of eighty-one days, dying on December 17. It was col- 
lected in flight just before dusk by Mr. G. B. Vogt as it was 
about to alight on a hop hornbeam tree near a rock outcrop 
located at an angle between Difficult Run, Virginia, and the 
Potomac River on September 28, 1955. No insects other than 
a small roach nymph, which was rejected, were offered to the 
mantispid, but bits of fruit such as peach, plum, grapes and 
cucumber were placed near the top of the small jar (2 oz.) 
in which the specimen was confined. It was not seen to feed 
on the fruit, although it appeared attracted, even reaching for 
the fruit with its forelegs. Water was splashed on it daily, and 
grass and chickweed kept in the jar. It was frequently seen 
to pass its forelegs and tarsi through its mouth. The day before 
death, it fell into about 4/' water, which had accumulated in the 
jar from the daily splashings, and after it was rescued, it became 
inactive and died the next day. Upon dissection, a moderate 
amount of fat was found next to the body wall of the abdomen, 
but eggs were not apparent. 

The above longevity record for an adult mantispid in captivity 
is greater than that of Hungerford (1936, p. 70), who was able 
to keep a female of M. interrupta Say alive sixty-seven days, 
from July 19 to September 24, by giving it "a few drops of 
water each day and a housefly or other insect for food." Mill- 
iron (1940, p. 359) fed a mantispid (from Central America?), 
which was tentatively determined as viridis, ten to fifteen dro- 
sophilid flies between October 30th and November 7th, when 
the mantispid died. Thus it is seen that M. viridis may over- 
winter as an adult in its natural habitat. Smith (1934, p. 124) 
suggested that M. interrupta and M. sayi may overwinter as 
adults because some were taken in October in Kansas. Viets 
(1941, pp. 70-71) reared an adult of M. interrupta from an 
egg. The parent was collected in the summer in Michigan and 
the adult offspring emerged two months and five days after the 
egg was laid. This might indicate hibernation by the adult. 
Brauer (1869, p. 833), however, after approximately sixteen 



206 ENTOMOLOGICAL NEWS [Oct., 1958 

years of research, found that the Palaearctic styriaca Poda over- 
wintered as a larva and did not seek a spider egg-sac until 
spring. Main (1931, p. 26) made similar observations on 
styriaca. 

SARCOPHAGID INVADER OF A MANTISPA 

A sarcophagid larva (Diptera, Sarcophagidae), approxi- 
mately 3 mm. long, identified by W. W. Wirth and C. W. 
Sabrosky, was found by the writer in the abdomen of a male 
of M. interrupta from Victoria, Texas, when it was dissected. 
It is not known whether the mantispid was alive or dead when 
the sarcophagid entered.

Three New Species of Haploneurion Kohl (Hymen- 
optera: Psammocharidae) from Chile 

By R. R. DREISBACH, Midland, Michigan 

Townes, in his paper * on the Nearctic wasps of the Subfamilies 
Pepsinae and Cerapalinae, places the species of this Genus and 
those of the Genus Sphictostethus Kohl in the Genus Priocneniis 
Schip'dte. The writer cannot agree with this. Both of these 
Genera have outstanding characters which are distinctly differ- 
ent from those in Priocnctnis. These differences are even 
greater than is usual between genera. The following key for 
the females (no males are known for the Genus Haploneurion} 
will show these differences. 

1 . Fore wings with tzvo cubital cells ; second recurrent vein 
meets second cubital cell from about apical fijth to slightly 
apicad of the second intercubital vein ; second intercubital vein 
strongly bowed outward on anterior third, the second cubital

to transverse vein ; in the fore wings the transverse vein 
apicad of the basal vein by two to three times the length of 
the transverse vein ; the wings very small, but probably func- 
tional, barely reaching apex of first tergite ; no teeth whatever 
on posterior tibiae ; eyes do not reach the vertex ; pronotum 
almost as long as mesonotum or longer ; scutellum prominent,

ent on posterior tibiae, very strong or weak ; pronotum not 
as long as mesonotum or if so thorax constricted behind the 
pronotum ; metapostnotum not so long or if almost so thorax 
constricted and wings with three cubital cells ; eyes reach the 
vertex or if not then three cubital cells and thorax con- 
stricted 2 

2. Thorax constricted just back of pronotum, pronotal shoulders 
much enlarged ; a very large mesopleural tooth just at the 
rise above the middle coxae ; propodeum with dorsal surface 
flat, very long, parallel-sided, posterior slope almost at right 
angles to the dorsal surface ; eyes do not reach the vertex ; 
wings small, hardly reaching to basal third of abdomen, but 
functional, the transverse vein in fore wings apicad of basal 
vein by almost twice its length ; teeth on posterior tibiae small ; 
tibiae hairy between teeth Sphictostethus Kohl 

2. Thorax not constricted, pronotal shoulders not enlarged ; no 
mesopleural tooth, not even a swelling ; propodeum slope 
without a differentiation between dorsal and posterior parts, 
not parallel-sided ; very short, not rough ; eyes reach vertex ; 
wings normal or in one case very small not functional, the 
transverse vein in fore wings apicad of the basal vein by 
much less than twice its length ; posterior tibiae generally 
strongly toothed, not strongly hairy between the teeth, or
