HOMOPTERA
ON THE GNATHODUS SPECIES OF THE ABDOM-
INALIS GROUP.
Cab BAKER.
Gnathodus abdominalis is one of the commonest species
of the group in the United States, being especially well
distributed in the southern two-thirds of this area. It is
the type form of a group of the old genus in which the
head is as wide or wider than the pronotum, and the ocelli
approach very closely to the eyes. These characters give
it an aspect very different from that of the original type of
Gnathodus.
I propose to here separate abdominalis as the type of a
new genus—Eugnathodus. In western Nevada I found a
new Eugnathodus, differing remarkably from abdominalis
in that the vertex was considerably produced. In western
Nicaragua I found the genus well represented, while ex-
tensive collecting failed to turn up a single true Gnathodus.
The genitalia are very similar in all the species, in the
female the hind margin of last ventral segment being
simply truncate, so far as observed.

AONE W GENUS OF PH TYPHLOCYBINI.
(OR 1 BVA OI Ree
In Typhlocybids with margined wings we find one
genus with three apical cells, two with two apicals, and
one with one. In those without a marginal vein we have
had cases of three cells (Eupteryx) and of two cells (Typhlo-
cyba) in the wing. To complete this parallel series now
comes a little Typhlocybid from Nicaragua, the smallest,
slenderest species I have seen in the tribe or even in the
family. This insect has the aspect of Typhlocyba and but
a single apical cell in a wing without a margin. The
elytron is altogether unique for it is angled at the apex,
making the large stalked second apical cell diamond-
shaped. I name the new genus Typhlocybella.
Typhlocybella minima n. sp.
Length 2.25 mm. Color sordid white with fine olive markings.
Face darker, with a tranverse line above. An irregular line runs
around apical and lateral margins of vertex within the border. The
pronotum bears four more or less distinct longitudinal olive lines.
Elytron transparent, the veins margined with smoky and_the apical
cells suffused with smoky. A golden cloud occurs near base of
corium. Tergum and venter mostly black.
Collected at Managua, Nicaragua by the author.
THE GENUS ERYTHRIA IN AMERICA.
(Oz ING MVE ace
In Nicaragua I found a number of small, thick set,
highly colored Typhlocybids, which have the venation of
Dicraneura, but differ widely from that genus in character-
istic proportions of body. They are exactly congeneric
with the European species of Erythria, and i shall de-
scribe them under that name, although none have yet been
described from America. I called attention to the possible
status of this genus.in ‘‘Psyche” several years ago,
Erythria Donaldsoni n. sp.
Length 3 mm. Color sordid yellowish with fine olive lineations -
and mottlings. Front with interrupted brown arcs below, above
with two olive loops extending over from vertex. Vertex witha
median line and two twice looped lateral lines which connect with
the median line on anterior margin. Anterior margin of pronotum
yellowish with four dark dots, the remainder mottled olive. Scutel
yellowish with two dark median dots anteriorly andtwo faint longi-
tudinal lines posteriorly. Elytron, except costal celt, nearly to
cross neryures finely yellow mottled on an olive background. Two
spots on claval margin distad of a ngle, and extreme apex of clavus
white. Apical third of elytron fuliginous, the veins white. Small
transparent spots in apical cells and larger ones in anteapical cells,
Collected at Managua, Nicaragua, by the author and named for
Hon. Chester Donaldson, U. S. consul there, and a thorough Amer-
ican gentleman, keenly alive to the interests of fellow countrymen.
Erythria Guzmani n. sp.
Length 2.75 mm. Sordid yellowish with lower part of face,
venter, and tergum black. Front with interrupted brown arcs.
Vertex with a brownish half loop on either side of front margin
and a fainter transverse line posteriorly. Pronotum with a group
of several brown dots on either side near front margin; most of
disc olive and hind margin whitish. Elytra with veins whitish
translucent, distally the veins are margined with fuliginous which
color entirely fills the inner and outer apical cells. Two yellow
areas in the clavus, one in the brachial cell, and two in the basal
cell. are narrowly margined with smoky. About midway in the
costal margin isa yellow elliptical ring, the breadth of which ex-
tends from costa across radial cell, and which is crossed length-
wise by a yellow line on the cubital nerve. At each end of this
ring is an irregular blackish area.
Collected at San Marcos by the author. Named for Dr. Guz-
man, the Director of the Nicaraguan National Museumat Managua.
Erythria Montealegrei n. sp.
Length 3mm. Face almost entirely black. Anterior margin
of vertex and upper margin of face broadly yellow. The vertex is
strongly produced. Passing across its middle from eye to eye and
arched cephalad is a narrow somewhat irregular blue-black band.
In front of this band the vertex is orange, behind it reddish. The
pronotum is orange colored with an irregular blue-black band just
within anterior margin The scutel is orange with a very broad
longitudinal blue-black band. Basal two-thirds of elytra orange,
the remainder faintly tinged with lemon yellow. On the elytra are
blue or blue-black markings as follows: A small spot at base of
| On
clavus, two large spots near middle which run together on clayal
suture, a spot at base of corium, a narrow band which starts on
basal fourth of costa, passes obliquely inward and distad to radial
cell, thence obliquely outward and distad to costa. from which point
a broad band crosses the elytron to apex of Clavus.
Collected at Champerico, Guatemala, and at Managua, Nica-
ragua, by the author. One of the most beautiful Typhlocybids seen
in Central America. Named for Senor Don Abraham Montealegre,
a Nicaraguan gentleman living in Chinandega, and former Italian
vice-consul, with whom I lived for a time and from: whom I had
many favors.
Erythria Deschoni n. sp.
Length 3mm. Headand thorax pale brown, the anterior mar-
gin of the strongly produced vertex yellowish. The vertex has
three faint whitish longitudinal lines, one median, and two lateral
oblique ones near it. Around anterior margin of pronotum are a
numober of minute white dots. The scutel also shows faint white
lines as on vertex. The elytra are clear yellowish brown through-
out, the clavus along ciaval suture being somewhat decolored.
Venter yellowish. Tergum black.
Collected at Managua, Nicaragua, by the author. Named for
Mr. Edward Deschon who, although a Nicaraguan gentleman by
birth, was educated inthe United States. To him I am indebted
for many kindnesses and much valuable information.
NEW TYPHLOCYBINI.

Alebra sanguinolinea n. sp.
Length 3.25 mm. Head large, somewhat tumid, strongly
pointed in front, the vertex rather narrrw, longer than wide. Color
pale yellowish with intensely blood-red markings.
Vertex with two small golden arcs just before apex. Propleura
and costa near base each with a small red dot. A broad red band
extends entirely around anterior and lateral borders of pronotum,
then follows claval suture half its length, where the two limbs
cross the clavus and join at the commissure. A red band starts
near base of clavus and extends to near middle of claval suture
where itis clavate. A third red band starts near middle of costa
and extends obliquely to near distal end of brachial cell. The
transverse veins between apical and anteapical cells are red. The
apical cells are smoky with a single transparent spot in each. There
6
are transpirent, sm>ky bordered spots in apical portion of each
anteapical cell. Near the middle of the costa between the lateral
red bands is a lemon yellow area, and another occurs in apical por-
tion of clavus. The tergum, except for small lateral portions, is
black.
Collected at San Marcos, Nicaragua, by the author.
Protalebra Nicaraguensis n. sp.
Length 3.5mm. Vertex strongly angled in front. Hind mar-
gin of last ventral segment of female broadly notched, with a large
rectangular tooth which does not exceed lateral angles of the seg-
ment. Color lemon yellow, paler on face and margins of vertex,
and on lateral angles of pronotum. The scutel becomes white
eaudad, the extreme apex black. ‘The elytra are glistening yellow-
ish, more transparent apically where the margin is narrowly
smoky. A round dot on cubital nerve, a transverse stripe on middle
of clavus, a transverse band at apex of brachial area, and another
still larger transverse band across the two inner apical cejls,
fuliginous.
Collected at San Marcos, Nicaragua, by the author.
Protalebra transversalis n. sp.
Length3 mm. Head pale yellowish. Pronotum, except lateral
angles, pale brown. Elytra glistening yellowish to the transverse
veins. Starting at middle of costa, a fuliginous band extends
entirely across both elytra. This band is narrow and deeply
colored at the costa, paler and much broader within where it is
extended along the inner margin of clavus to and around the basal
angle. The area of the apical cells is fuliginous, with a transverse
band just back of apex and a spot at base of inner apical cell trans-
parent. The form of the apical cells is quite peculiar. The inner
terminal vein is lacking, throwing the two inner apical cells
together in one very large cell.
Collected at Acapulco, Mexico, by the author.
Protalebra maculata n. sp.
Length 2.5 mm. Blackish, with ivory white or yellowish
markings. Vertex broad and obtusely angled in front. Hind
margin of last ventral segment of female truncate.
Face dark brown below, black above where there are two trans-
verse yellow stripes, the lower passing on to basal joiuts of an-
tennae, and having, where it crosses the front, several brown dots.
The apex of vertex is black; back of this black apex is a transverse
yellow band enlarged at center into a diamond shape, and at sides -
passing down to join the upper band on face. There are two large
yellow spots at posterior angles of vertex.
The pronotum is black with a narrow white margin Onits
disc anteriorly is a large rounded white spot, and on either side of
center are two more, connected by a lozenge shap2d white spot.
The scutel, except lateral angles and a median spot next pronotum,
is white. The elytra are dark fuliginous. In basal half of clavus
are three white spots, the middle largest, the distal sometimes
broken in two. There is asmall white dot at the apex of theclavus,
another just beyond tip of clavus, a large one on distal end of
brachial vein and a smailer one at proximal end of the anteapical
cell. The veins surrounding the middle anteapical cell are white.
A small area across the two inner anteapical cells. a small area in
each of the two outer apicals and the outer anteapical cell, trans-
parent. A small space at apex of elytra and three small spaces
along the costa proximally, white.
Collected by the author at San Marcos and at Managua in
Western Nicaragua.
Protalebra octolineata n. sp
Length 3 mm. Pale golden yellow above, whitish beneath.
Head without markings. Three more or less distinct longitudinal
lines on pronotum, the middle extending on to scutel where it is
much more deeply coloured. The elytra are unevenly glistening
yellow proximally, transparent distally. Kach elytron on basal
two-thirds bears four dark longitudinal lines about equidistant, one
passiny along costa, one along cubital vein, one through the clayus
and one along outer claval margin; the twoinner curve toward each
‘other distally and join, asdo also the two outer. Area of apical
celis slightly smoky, with two narrow darker bands apically; one
spot in outer and another in inner apical cell, dark brown. Hind
margin of last ventral segment truncate with a transverse black
mark at center.
Collected in considerable numbers at San Marcos and Managua
in Nicaragua and at Champerico, Guatemala, by the author.
Eualebra notata n. sp.
Length 3 mm. Golden yellow, the face brownish, and the
anterior margin of vertex lighter laterally. At base of vertex on
the median line is a large rounded black spot. On either side of the
paler apex of the scuteJlum is a small black dot. Another black
dot occurs at extreme base of elytron. Elytra very pale smoky
with pinkish suffusions especially along the principal veins.
Collected at Champerico, Guatemala, by the author.
Empoasca lineata n. sp.
Lenyth 3.5mm. Vertex rather strongly obtusely angled. Color
pale green, the legs bluish green distally. Two broad golden yel-
low bands cross the vertex longitudinally next the eyes and pass
caudad across the pronotum; a band follows the claval margin of
elytra from base, around the angle, and to two-thirds its length.
Another broad golden yellow band passes along the claval suture.
Another band, very indistinct, appears onthe middle of the corium.
The elytra, except veins, become transparent distally.
Collected at San Marcos, Nicaragua, by the author.
Eupteryx quinquemaculata n. sp.
Length 3.25mm. Sordid white, yellowish on face, middle of
vertex, scutel and bases of elytra. The front below has many
broadly inter-npted brown arcs and above near center two round
black spots. A round black spot occurs on either side of apex of
vertex and another on the median line near base. Twosmall black
dots occur near middle of anterior margin of pronotum and two
still smaller occur on either sidecaudad of these. A large area in
middle of pronotum posteriorly, isdarkened. The elytra are nearly
transparent with the veins smoky margined. ‘Three small fuligi-
nous areas occur in the clavus and another at the middle of the
brachial cell. There are two small dirk dots near the costa prox-
imally, two larger still darker ones near costa at middle, and one
small one at tip of middle apical cell.
Collected at Stanford University, California, by the author.
This is the third American sp:cies of this genus.
Typhlocyba pseudo-maculata n. sp.
Length 2.5mm. With the general appearance of maculata,
but much smaller, the vertex much narrower and far more strongly
produced. Color milky white, with golden markings. On the
vertex there are two longitudinal bands next the eyes, which do not
join at the apex. On the pronotum there are four longitudinal
bands, two on sides and two near the middle, the latter converging
toward the hind margin. Lateral angles of scutel golden. Three
spots on claval margin, one before the angle and two beyond. On
the corium occur two oblique golden stripes, one at basal fourth and
one at half the length, both extending from costa inward and back-
ward. ‘The veins apically are faintly smoky margined, and at base
of middle apical cell occurs a round black dot.
Coiected at Champerico, Guatemala, by the author.
Typhlocyba verticis n. sp.
Length 3mm. Peculiar among Typhlocybids because of the
extensive vertex, which is not only broad but strongly angularly
produced as in Deltocephalus.
Color pale yellowish, the head and pronotum without markings.
Clavus and corium at base, golden. On middle of corium is a large
g
rounded milk white area partly surrounded by a more or less imper-
fect carmine border which is more distinct near the costa. Some
of the apical veins are smoky bordered and at the base of one ot fhe
apical cells is a large round black dot.
Collected at Managua, Nicaragua, by the author.
Typhlocyba pseudo-obliqua n. sp.
Length 3.5mm. Color very pale yellowish with red markings.
Two separate longitudinal bands on vertex next eyes are extended
straight caudad across pronotum. Lateral margins of pronotum
red. Lateral angles of scutel and a median line red. A transverse
red band passes across Clavus just proximad of the angle. An ob-
lique red stripe starts from basal fourth of costa and passes across
apical third of clavus. Another red stripe starts from half of costa
and runs obliquely to distal point of clavus. Elytra translucent
proximally, but transparent distally.
‘Collected at Managua, Nicaragua, by the author. Like obliqua
in general appearance, but smaller, and the markings arranged
very differently.
Fyphlocyba bimaculata n sp.
I had set this species aside as a Cicadula. It had the general
habitus of that genus, also the general color of some Cicadul/a, and
seemed too large and coarse for a Typhlocybid. But the venation
is that of 7yphlocyba, even to the absence of a marginal vein in the
wings.
Length 3.5 mm. Color yellowish, the pronotum darker. Two
large round black spots occur on the short, broadly rounded vertex.
Two rounded black spots occur near basal angles of scutel. Area
of apical cells transparent; the rest of the elytron golden translu-
cent. Tergum mostly black. Hind margin of last ventral segment
of female roundly produced at middle where it is brown.
Collected at Champerico, Guatemala, and at Acapulco, Mexico,
by the author.
NOTES ON MACROPSIS.
C.oh. BARKER:
In Psyche, Vol. IX, p. 55, I described Macropsis idio-
ceroides, which of known genera could only be placed in
Macropsis. From that genus it differed in some very
striking characters, notably in the position of the lateral
pronotal carina, which does not reach the eye but curves
far down on to the pleura. The head is very little, if any,
narrower than pronotum. ‘The clypleus is strongly convex,
very broad at base, suddenly strongly narrowed beyond the
middle to the rounded apex. In these characters it is
entirely distinct from all true Macropsis and I here separate
it as the type of a new genus, Straganiopsis.
Since writing on Macropsis in Psyche, I have collected
considerable additional material in Nevada, California and
Central America. I have already presented a reply to
Ball’s criticism of my paper. Further study of mew ma-
terial has afforded abundant additional evidence that some
of Ball’s speculations concerning the species are most ill-
founded.
The species humilis and misella were described by Stal
from Mexico, the latter from Vera Cruz. No structural
characters of specific value are given in the descriptions.
The length of both species is given as 4 mm. Colors only
are described and these are certainly somewhat variable in
this genus as in most Jassid@ just as Ball says. The types
are probably in existence and should be given careful
examination and description. Ball’s reference of rufoscu-
tellata to misella would also warrant, and more plausibly,
the reduction of some forms of robusta also. In 1902 I
collected in Nevada a good series of rufoscutellata fairly
typical and uniform in characters, and I again insist that
there is no evidence whatever to indicate that it is more
closely related to misel/a than are several other species.
The reference of atra, magna and Californica to humilis
is still more uncertain and ill-advised and would suggest
the possibility of aggregating all Macropsis into one
species. Not only are atra, magna and Californica widely
distinct from each other and from pymilis in coloration,
but the three former present a number of pronounced
structural differences, and are very dissimilar in size.
Humilis is characterized by colors only, with a length of 4
mm. ‘There would be far better reason for reducing Stal’s
pallescens (which I have collected in Nicaragua) to humilis,
and Ball should have done it, to be consistent. It becomes
bl
somewhat humorous, when, after indicating that the three
species in question bave not even specific value, he de-
scribes a var. paeta, ‘suffused with reddish,” of the species
laeta. Just so we might have a var. nigra of many Jassids
and a var. albiflora of most plants with colored flowers.
For any who may wish to compare the species atra, magna
and Californica with each other and with the descriptions
of humilis and misella, | transcribe these latter from the
original source.

broadly rounded. Margins of ledges over antennal grooves strongly
oblique. Front just above clypeus nearly smooth. Pronotum with
the usual aciculations. Hairs on basal third of elytra very pale
brownish and rather weak, on apical two-thirds (except area of
apical cells) much stronger and black.
Color very variable. Ground color sordid straw color, some-
times somewhat greenish. A small areaon hind margin of prono-
tum usually darker, sometimes even black. Basal angles of scutel
dark, sometimes blackish. A spot at miéedle of claval margin and

Macropsis Franciscana n. sp.
Female. Length 4.25 mm. Resembling su/oscutellata, but
shorter for the breadth. Vertex slightly produced at middle.
Clypeus with sides gradually converging towards apex. Margins
of ledges over antennal grooves nearly in a straight line, but
slightly oblique. Front just above clypeus distinctly aciculate.
Pronotum with the usualaciculations. Impressed line on middle of
scutel gently curved, not angled at middle. Basal half of clavus
with adjoining portion of brachial cell, bearing numerous minute
white hairs. The remainder of corium, except apical cells, bears
black hairs. ‘The first (inner) apical cell is smaller than second.
Color pale green with a yellowish tinge. Scutel yellowish, the
impressed line often darker. Clavus bordering scutel and to beyond
inner angle, red brown.
Last ventral segment broadly, evenly, deeply emarginate,
with a small triangular projection at center.
Collected at various points in San Mateo and Santa Clara

representative of 7u/oscutellata but of different proportions, details
of structure, and color.

ORTHOPTERA
FIRST DECADE OF ORTHOPTERA ISSUED IN THE
“INVERTEBRATA. PACIFICA” SERIES:
Cai k: BAKE Re
The. first decade of Orthoptera now being issued to
subscribers contains four new species, Professor Morse’s
descriptions of which are quoted in this paper. He is also
authority for all the determinations. All the material for
this first decade was collected in Ormsby county, Nevada,
by my wife and myself. We took all these, together with
others, in the lower edge of the pine zone west of Carson
City, among pine groves and sage brush openings at from
1700 to 2000 metres. This first decade is as follows:
17. Cordillacris affinis Morse n. sp.
15. Stenobothrus acutus Morse n. sp.
20. Bruneria shastana Scud.
310. Aulocara elliottii Thos.
307. Hippiscus neglectus Thos.
5. Trimerotropis juliana Scudd.
6. Trimerotropis bifasciata. Mc N.
8. Hesperotettix Nevadensis Morse n. sp.
19. OUedaleonotus enigma Scudd.
24. Bradynotes compacta Morse n. sp.
Of these No. 310 was abundant, Nos. 6, 307 and 19
were fairly common, Nos. 17, 15,.20, 5-and.18 were infre-
quent and local. Perhaps the most: interesting species is
14
No. 24, the new Bradynotes. This was found common in
the sage brush after we became familiar with its habits.
It is wingless and a poor jumper, but expert at ‘“‘playing
possum.” When the bushis jarred it drops at once and
lies on the ground with legs folded against the body. In
this condition it is very difficult to find.
ADDITIONAL NOTEHS JON. PACIFIC CONSE
ORTHOPTERA.
Cob BAKER:
Of the past year’s collecting in Nevada, Middle West-
ern California, Southern California and Western Nicara-
gua, but a small number of species have been determined,
though practicaliy all are in the hands of specialists.
Besides the Nevada species to be issued in the first de-
cade, there were also collected in the same locality Camnula
pellucida Scudd., very common; one of the ‘*Jerusalem
Crickets”, Cacopteris inermis Scudd.common; Trimerotropis
fallax Sauss., and Niphidium occidentale Morse, occasional;
under boards, logs, and stones the curious Stenopelmatus
longispina Brunn., occurred frequently. Some of the Ne-
vada Melanopli are still undetermined.
At Stanford University, California, I found Welanoplus -
devastator Scudd., and M. nanus Scudd. fairly common and
in about equal numbers. Yiphidium occidentale Morse is
also not uncommon there. Under boards, logs and stones
at Stanford there may frequently be found the very inter-
esting Ceuthophili—c. pacificus Thom., and C. henshawii
Scudd.
NEW ORTHOPTERA FROM NEVADA.

margin of the vertex, being nearer a line drawn at the level of the
front margin of the eyes than to the apex of the vertex—in occipi-
talis the reverse is true,—and the fuscous stripe on the dorsal part
of the outer face of the hind femora is broken up into narrow trans-
verse fasciae. "The name CORDILLACRIS has been proposed by Rehn
(Can. ent., vol. 33, p. 271) to replace ALPHA (Brunner, Rev. syst.
orth., p. 121, 1893) which is preoccupied in Hymenoptera.
STENOBOTHRUS ACUTUS, sp. noy.
Five males, Ormsby Co., Nev., July 6. Closely allied to S¢#.
cnrtipennis but differing in having the vertex more produced and
the angle of its sides more acute; the facial costa is also wider and
scarcely or not at all narrowed opposite the median ocellus. ‘The
lateral foveolae are deep and very distinct, and the antennae aver-
age shorter (in the specimens seen). Possibly it is but a geograpi-
cal race but in either case it seems worthy of a name.
Antenna, 8.5-9.5; hind fem.: 11-12; tegmina: 10-12; total length:
16-17.5 mm. The tegmina equal the abdomen.
HESPEROTETTIX NEVADENSIS, Sp. nov.
Three males, three females, Ormsby Co., Nev., July 6. Very
similar to A. brevipennis, the female somewhat smaller, differing
in ornamentation and slightly in structure, the vertex being a very
little narrower between the eyes,and the tegmina relatively shorter,
especially in the male. ‘The tegmina in both sexes are about one
and one-third times as long as the exposed portion of the abdomen
(in bdbrevipennis nearly or quite covering abdomen, particularly in
male). General color pea-green, ranging (in-male at least) to rusty
brown, and varied with pale yellow stripes on mid-carina and on
anterior portion of lateral carinae of pronotum, on meso- and me-
tapleura, lower margin of genae, lower margin of outer face of
hind femora, and on the veins of the tegmina, especially the poste_
rior ulnar. Hind femora with ferruginous annulus above knee, in
brown male showing indications of two obliquely transverse fus-
cous fasciae. Hind tibiae bluish green, palerat tip. Fuscous mark-
ing and cloudings are also present in varying degree on the lateral
lobes of the pronotum and along the margins of the median dorsal
pale stripe. on the vertex and occiput, the meso- and metapleura,
andthe geniculations of the hind femora. The anterior and middle
femora are ferruginous.
Antenna: male, 7; female, 7; hind fem: male, 9; female, 11.5-
12.5; tegmina: male, 6.3-6.7; female, 8.5-9; total length: male, 16;
female, 21 mm.
BRADYNOTES COMPACTA, Sp. nov.
Four males, four females, Ormsby Co., Nev., July 6.
Nearly allied to #%. odesa, differing from that species in its
smaller size, the structure of the pronotum, the less upturned end
16
of the abdomen, and in the form of the supra-anal plate of the
male. In odesa this plate is as wideas long, in’ compacta it is dis-
tinctly longer than wide. The lateral carinae:of ‘the pronotum are:
equally as distinct or even better developed than in odésa and less
irregular in course, in obesa being broken or angulate at the anterior
and middle sulei, formmg two pairs of lines; diverging posteriorly,
while in compacta they form essentially but one pair of divergent
lines though somewhat sinuous (female) or subangulate (male) at
the crossing of the sulci.
Antenna: male, 7; female, 7; hind fem.; male, 10-10.6;° female,
10.5-11.5; pronotum: male, 3.7-4.2; female, 4.2-4.5; . total length:
male. 18-19:5; female, 20-25 mm.?’

REPORTS ON CALIFORNIAN AND NEVADAN
DIPTERA i:
Cc. F. BAKER.
Only through the kindly interest of Mr. D. W. Coquil-
let of the National Museum, does it become possible to
publish these first results of the collection of the past year,
at this time. Acknowledgments are also due Prof. J. M.
Aldrich for the determination of most of the Dolichopo-
didae.
The material recorded herein was all collected in three
regions, Ormsby County, Nevada, the vicinity of Stanford
University, California, and about Claremont, Los Angeles
County, California. The work done so far has been any-
thing but thorough, and taken all together represents but
very few hours actual labor. Indeed, the results are but a
by-product of other very pressing work. It will be noted
that the Stanford material is composed entirely of vernal
and autumnal species, since I have never been there
through the midsummer,
All the Nevadan material was taken by my wife or
myself about our summer camp in the head of King’s
Canyon west of Carson City. The tents were placed just
within the pines. Near them, in a tangled patch of wil-
lows and alders, welled upa smallspring which supplieda few
acres of meadow on the hillside below. Quite a variety of
herbaceous plants grew in this vicinity. On the other
side a few steps carried one among the sage and rabbit-
brush (Chrysothamnus). Even though so manifestly in-
complete, still the comparison of these collections is very
18
interesting, the Californian from west of the Sierras and
the Nevadan from close up on the eastern slope.
The vicinity of Stanford University furnishes a wealth
of Diptera which I have not seen equalled anywhere in the
West. There are ponds, streams, rich woods, pastures,
and finally salt marshes, all near by. ‘The richness of the
region may be inferred from the large number of new
species resulting from the small amount of very superficial
work done by me.
At Claremont and vicinity, in the typical Southern
California country, work has just begun. It will be con-
tinued with unremitting perseverance in both California
and Nevada.*

a large brownish spot behind the fifth vein appears to represent
the continuation of this band; the second band crosses the wing
from just before apex of the first vein to apices of forks of the fifth
vein, filling the cell formed by these forks, behind which it is
abruptly narrowed to about half its previous width; the third band
fills the apex of the wing from a short distance beyond apex of first
vein to apex of upper branch of fifth vein; the latter vein forks far
beyond the forking of the fourth, its forks rather narrowly sepa-

2617 Oecanthus Californicus Sauss.
Frequent at Claremont, California. Det. Rehn.
2616 Oecanthus marcosensis Baker n. sp.
Specimens collected at San Marcos, Nicaragua and of the same
general habitus as californicus. had been doubtfully referred to that
species by Rehn. No. 2617 he had determined as true ecalifurnicus But
marcosenst, differs widely in the majority of the specific characters,
coloration, form of body, structure of antennae, etc., though it is
evidently a near relative. Type in my collection.
Length 18 mm. Color a faded brownish, darker on the posterior legs.
The antennae are stout, the two basal joints brownish, and each with a
slender, longitudinal, dark brown dash beneath; the flagellum is straw
colored and with short white pubescence; joints 3 and 4, 6 to 10 inclusive,
12, and 16, are short and subequal; joints 5, 13, and 17, are slightly
longer and subequal; joints 11, 14, 15, and 18 and suceeding joints, are
about twice as long as the smallest joints and subequal in length. The
maxillary palpi are about as long as the head, joints 3 and 4 subequal,
joint 5 longer and most swollen in the apical half. Labial palpi small,
the third joint longer than the first two together and but slightly swollea
towards the normally rounded tip. Pronotum narrowed anteriorly, the
sides neither strongly depressed nor much expanded; near the medi:n
line are three pairs of small longitudinal depressions; near the frout
margin on either side is a short semicircular depression, while posterioy
to these are a pair of long, curved, deep longitudinal depressions. The
tegmina are 14 mm. long by 5.5 mm. wide at the widest place; on the
reflexed portion are fourteen oblique veins. The wings reach to the tips
of the tegmina. The cerci are rather stout, extending to the wing tips, and
covered with rather long white hairs of varying lengths. The hind femora
have three longitudinal series of short, oblique, straight brown dashes
on the outer side, while both femora and tibiae are sprinkled with minute
brown dots; the tibiae bear five pairs of large spines besides the numerous
small teeth; the apex of hind tibiae and the hind tarsi are thickly
covered with a short golden pubescence.
2613 Oecanthus niveus DeG.
Oceasional in the mountains near Claremont, California. Det. Rehn.

Rehn.
1289 Oecanthus nigricornis Wlk.
Frequent at Stanford University, California. Det. Rehn.
1302 Oecanthus Rileyi Baker n. sp.
This new species is described from one male taken in the mountains
near Claremont, California. Mr. Rehn had referred it to Ovecanthus
82
latipennis Riley , temporarily, as the most nearly related form. But this
can scarcely be that species as the description will indicate. The tyne
is in my collection.
Length 15 mm. Color, the faded yellow common to many species of
Oecanthus, The anterior and middle femora are pale brown. The anten-
nae are clear shining amber color; the two basal joints are brown and
each has on the under side an ivory white area with a small round dark
brown dot at center; the flagellum is very slender, about 16 mm. in length
and very minutely and sparingly pubescent; joints 2 to 11 inclusive. of
the antennae, and 14 and 15, are short and subequal in length; 12 and 18,
and 16 and immediately succeeding joints, nearly twice as long as those
in the first lot. Joints 3 and 4 of maxillary palpi equal; joint 5 as long as
first three together and medially somewhat swollen. Basal joint of labial
palpi small, second slightly more than twice as long, third as long as first
two together and gradually enlarged to a truncate tip. Pronotum narrow-
ed anteriorly, with two small slender curved longitudinal depressions
laterally on disc; the sides are first strongly depressed and then expand-
ed. The tegmina are 12 mm. long by 4.5 mm. wide at the widest place;
the reflexed lateral portion has eleven oblique veins. The wings exceed
the tegmina by 1 mm. The cerci attain the tip of the wings and are
thickly pubescent with silvery white hairs. The hind tibiae bear five
pairs of large spines besides the numerous small teeth.
3428 Oecanthus Rehnii Baker n. sp.
With No. 1302 I had placed a specimen taken at Stanford Uni-
versity, California, which was almost identical in general form. On
examining it critically | am surprised to find that it differs in almost
all the specific characters in use in the genus. The type will remain in my
collection.
Length 14 mm. Color as in rileyi. Anterior and middle femora of
the same color as the rest of the body but the hind femora are browniss.
The antennae are quite stout, 22 mm. long, opaque, brown in color ant
covered with a tolerably dense minute pile; the articular nodes are white,
producing a ringed appearance; the two basal joints are yellow; the
first has beneath and within a heavy black longitudinal stripe, and a
roundish black spot apically and outwardly; the second joint is almost
covered beneath with a large black spot which is notched with yellow
apically; joints 2, 38, 5 to 8, and 10 and 11, are short and subequal,
joints 4 and 9 are once and a half as long, joints 12 and 13 are twice as
long, 14 the same length as the first lot, while 15 and succeeding joints
are again long and subequal. Palpi and thorax about as in rileyi The
tegmina are 10.5 mm. long by 4 mm. wide a the widest place; the reflexed
lateral portions have twelve oblique veins. The wings exceed the tegmina
by 1 mm. The cerei are as in rileyi ‘The hind tibiae bear six pairs of
large spines besides the numerous small teeth. The apices of the hind
tibiae and the hind tarsi are piceous.

white pubescent except above and in front where the hairs are yellow-
ish and brown. Sutures of pronotum without*plumose hairs. Mesonotum
shining and with very large and close punctures, becoming rugosely
punctured on the sides; with two rather distant, distinct, longitudinal
grooves on either side, but these do not reach the anterior margin.
Scutellum opaque, coarsely rugose. Metanotum shining, very coarsely
reticulated, the meshes of the reticulum subequal except for two unsy-
metrical long narrow ones in the middle above. Mesosternum rugoso-
punctate and armed with two short teeth near the median line. Legs

on mid and hind tibiae. Tegulae honey yellow. lore wings with the
apical third pale smoky; nervures dark, stigma piceous, apex of margin-
al cell obtusely pointed; first recurrent nervure entering second sub-
marginal cell before the middle of its lower margin; transverso-median
nervure joining the externo-median in front of the basal.
Abdomen shining, and rather densely clothed with white, yellowish,
and brown hairs. The length of first segment viewed from above is
less than twice its breadth at apex, the sides are not straight, for apical-
ly it is swollen to almost nodose, though it is not as strongly constricted
at juncture with second as in some other species; basally this segment
is rugoso-punctate but on the nodose portion very sparsely and remotely
punctate; near its apex are a few plumose hairs; the median ventral
ridge is not prominent and is bisinuate. Pubescence on first and second
segments thick and whitish above and below; the apical margins of
segments II to V are provided with dense rows of yellowish plumose
hairs; segments III and following are finely transversely aciculate,
and finely punctate apically. The last dorsal segment is opaque, thickly
finely punctured, nearly nude, and with tufts of golden hairs at apical
angles. Second segment with the usual felt lines and third segment with
the usual speculum.
In Viereck’s synopsis this species would fall into the concolor of
Cresson, but differs widely from mellicornis which also runs to the
same species. The type was taken at Claremont, California. It is named
for Prof. A. J. Cook, one of the oldest American entomologists, who
is now living at Claremont.

broad behind the eyes, but head subtriangular, viewed laterally. Viewed
from above the head is very broadly semicirculariy rounded behind. Ver-
tex smooth and shining with very few subobsolete punctures, and thinly
clothed with yellowish hairs which are mostiy directed cephalad; the
two hind ocelli are much nearer to each other than to the eyes. Genae
coarsely punctured and with the oecipital margin bearing many long
yellowish hairs and some short white ones. Gular region with a pateh
of long white plumose hairs. Of the articles of maxillary palpi, II and
III are subequal in length, IV and V are subequal and three-fourtis

widely separated.
Tegulae and legs honey yellow, the femora and tibiae with darker
tips. Wings faintly smoky, especially on the apical half; veins pale
yellowish, stigma dark brown; apex of marginal cell obtusely pointed;
the first recurrent nervure entering the second submarginal cell at the
middle of its lower margin; transverse median nervure in line with the
basal.
The abdomen is shining, very hairy, the simple hairs above mostlv
yellowish; second segment with the usual felt lines. First segment
rugoso-punctate, seen from above rather short trapezoidal, length about
once and a half the width at base, the sides nearly straight, lateral
tubercles small, the segment rather strongly-swollen apically and clearly
constricted at juncture with second, the ventral ridge somewhat bi
sinuate and obtuse dentate basally. Second segment obscurely and
sparsely punctured. Last dorsal segment long trapezoidal, the surface
mostly shagreened and shining, with fine punctures before the apizai

margin; apical angles with tufts of short golden hairs; the slender
brown styles are here extended to half the length of this segment.
This species is very clearly distinguished by the sculpturing, and dis-
position of-the pubescence. It was collected at Claremont, California.
4041 Odontophotopsis mellicornis n. sp.
Length 11 mm. Castaneous, with white pubescence. Head subtri-
angular as viewed from the side, sloping behind the eyes, not at ali
quadrate; viewed from above it is broadly semicireularly rounded
behind. Vertex shallcwly, irregularly, and sparsely punctured, and with
rather short white hairs; occiput and genae fringed with much longer
hairs, those on the gular region also long and mostly plumose. Ocelli
with the two posterior nearer to each other than to the eyes; space
between the ocelli black. Antennae honey yellow, the scape punctured
and white pubescent, the first article of flagellum not as long as the se-
cond. Mandibles whitish pubescent, and with a blunt tooth subtending
an emargination on the lower border; the tips are black and bidentate.
Maxillary palpi with articles II, III, and V of equal length, IV a little
shorter.
Thorax rather thickly white pubescent, the hairs thickest and longest
on prothorax, mesothorax, and scutellum, and with rows of short
plumose hairs along the sutures of the prothorax. Mesonotum shining
and distinctly but rather sparsely punctured, and with two fine long-
itudinal grooves on either side. Scutellum opaque and finely rugose.
Metanotum shining, coarsely reticulated, the meshes larger and sub-
equal medially, smaller at the sides. Mesosternum punctured, sparsely
in front, rugosely behind, and armed with two short teeth near the
median line.
Legs honey yellow, apical two-thirds of mid and hind femora black-
ish, the mid and hind tarsi similarly though not so deeply blackened.
Tegulae pale honey yellow. Wings nearly hyaline except for a small
cloud in the marginal cell next the stigma; the veins are honey yellow
and the stigma pale brown; apex of marginal cell obtusely pointed;
the first recurrent nervure enters the second submarginal cell at the mid-
dle of its lower margin. ;
Abdomen mostly shining and with numerous long white hairs equally
numerous above and below, and specially dense on the apical half,
near the margins of the segments; hind margin of third and succeeding
segments dark brown; first abdominal segment long trapezoidal as
viewed from above, its length less than twice the breadth at base,
strongly constricted at its juncture with the second, below with a strony,
rough, evenly curved median ridge; at base and apex of first segment’
and at apices of second and third segments, passing around the
abdomen, are fringes of short plumose hairs, the fringe on second
segment thickest and most conspicuous; the second segment is very
sparsely punctured; the pubescence on the apical segments has a yellow-
ish cast; last dorsal segment punctured near the basal angles, and with
several shallow depressions apically, the apical angles with tufts of
short golden hairs.
This form is close to the concolor of Cresson as that species is
describet, but the two differ in various details. In mellicornis the
ocelli enclose, but are not ‘‘enclosed by’’ a black area, and the abdomen
is blackish apically. A sufficient characterization of the original con-
color bas never yet been given. So far as the original’ description is
concerned, several perfectly distinct far western species might, with a
superficial examination, be thrown into it by the careless interpreter.
4042 Odontophotopsis viereckii n. sp.

It seems to be sufficiently differentiated from ‘‘regulus’’ by the longer
elypeus compared with its width, it being also wider above. not so
clearly narrowed and its apex is clearly bidentate. Judging by Saussure’s
figure (Pl. I, f. 7 b) the abdominal petiole is longer compared with
the head and thorax; in regulus it is shorter than the head and
thorax; in the present species clearly longer than the two combined.
The second recurrent nervure is not interstitial as it is in FE. toton-
acus; in that species, too, the antennal hook is ‘‘very small.’’ £E.
aviculus should, inter aila, be known by its strongly punetured
abdomen.

DESCRIPTIONS OF NEW SPECIES OF TIPHITDAE FROM NEVADA
AND SOUTHERN CALIFORNIA.
BY P. CAMERON.
Very little has been done towards the elucidation of the North Amer-
ican species of Ziphia and the allied genus of Paratiphia. It is not
surprising therefore that Prof. Baker has discovered several undescribed
species,
Only one species of Paratiphia has hiterto been recorded from North
America, namely, albilabris Spinola; Saint Fargeau, Nat. Hist. des
Hymen. III, p. 556, from California, which I have not been able to
recognize from the too short description, which might be sufficient if
only one species were known, but is quite inadequate when it fits two
or three. It seems to be larger than any of the males known to me. ‘Io
complete my paper I give the description of ‘‘albilabris’’: ‘‘ Entirely
black, with yrey hairs. Clypeus white. Abdominal segments ciliated
with grey hairs. Legs black, their pubescence gray. Wings hyaline,
nervures and costa red; stigma and tegulae black. Male. Length three
and one-half lines. California.’’
There is an interesting sexual distinction shown by the males and
females of Paratiphia. In the females there is only a somewhat tri-
angular area on the base of the metanotum; in the males there are
two rows of longitudinal keels, forming small areae.
The species which I described in the Biol. Cent. Amer. II, pp. 235-239,
under Epomidiopteron are to be referred to Paratiphia, which I then
could not very well separate from the descriptions given by Sichel
(Saussure, Cat. Spec. Gen. Scolia, pp. 264-269). According to Ashmead,
Canad. Ent. 1903, p. 39, ‘‘Epomidiopteron DeRomand is some thing
quite different and is apparently allied to Engycistus \ox. In the fe-
male of De Romand’s genus the radial cellule is closed at the apex, the
fore tibia is produced into a long acute spine at the middle, and in the
male the first transverse cubital nervure is entire, not obliterated at
the base.’’ I have not access to DeRomand’s paper, and cannot, there-
fore, come to any conclusion in the matter; but I may point out that
Smith shows in his plate FH julii ©DeRom. to have a broken first
transverse cubital nervure and seems to be congenerie with Para
tiphia 12-maculata. J’am., Trans. Amer. Ent. Soc. XXX, 94. These large,
yellow-spotted species appear certainly different from the small, black,
densely haired ones.
Smith’s Tiphia clypeata, male, (Deser. of New Species of Hymen.
p- 187) from Mexico is no doubt a Paratiphia, judging from its white
mouth and mandibles. The metathorax is described as ‘‘longitudinally
rugose; the usual three carinae not distinctly observable, but parallel
and rather wide apart.’’

teeth, the basal short, blunt, indistinct, the last (and outer) much thin-
ner than the others and slightly longer than the penultimate. Length 45
mm. Ormsby county, Nevada.
This is a smaller and more slenderly built species than vari.
punctata; it may be easily separated from it by the metanotal area
being narrower and clearly longer than wide.

Genus Photopsis Blake.
Here belong a large part of the male forms which fly to light at night
so commonly in many parts of the west. Sometimes dozens may be
collected on a single evening and then again weeks may elapse without
seeing one. Hence it is only through residents in the southwest that ade-
quate collections will ever be made or the sexes properly associated. The
following forms are, of course, all described from males. Among these
species, the two posterior ocelli are usually about the same distance from
each other as from ‘the eyes. The reticulation of the metanotum is as a
rule much more regular than in Odontophotopsis, and the abdominal
fringes of plumose hairs occur on rarely more than one or two segments
in these species and gre sometimes entirely wanting.

more weakly sculptured than the lower portion of the mesopleurae. Scute-
Hum reticulato-punctate. Metanotum coarsely and very regularly reticu-
lated, with four larger longitudinal areas anteriorly, the two inner each

domen.
Second article of flagellum but slightly longer than the first. Mandibles
with the inferior tooth unusually large, the lower margin shallowly emar-
ginate on apical half, the subtending tooth low, broad, and very blunt. The

especially on the abdomen.
Second article of flagellum but slightly longer than the first. Mandibles
with the emargination below barely evident and the subtending tooth
very small. Interocellar space piceous.
The depressed area on mesopleurae above is very large and shallowly
reticulato-punctate, bounded caudad by a sharp brown carina which is

apically, the crenulate ventral ridge strong and bisinuate but without
prominent teeth. Felt lines concolorous. The second segment entirely
lacks a fringe of short plumose hairs though it has many long simple
ones.
Collected at Claremont, California. In the absence of a fringe of plu-
mose hairs on second abdominal segment and in the mesopleural charac-
ters this species differs remarkably from all others of this collection.
4336 Photopsis difficilis n. sp.

mid-coxae, above with a rather sharp transverse groove, the sparsely
punctate area small, not sharply demarked, the remainder sculptured like
that below. Scutellum with rather sparse indented punctures. Metanotum
coarsely, sharply, but quite irregularly reticulate with four median lon-
gitudinal areas at base, the two median each formed by the coalescence
of about four meshes, the two lateral each by about two meshes of the
reticulum. Wings with outer half smoky and a hyaline area over second
recurrent nervure; the second submarginal cell is large and sharply pen-
tangular.

article of antennae testaceous, the flagellum piceous. Pubesecence above
largely pale ochraceous. The bidentate mandibles have the lower side
very deeply emarginate leaving the distal portion unusually slender, the
subtending tooth large, broad, and very bluntly rounded. Interocellar
space slightly darkened; the hind ocelli large and nearer to each other
than to the eyes.
Mesopleurae deeply cut to three fourths of the width by a deep trans-
verse groove, the dise below this strongly rticulato-punctate, above the
depressed area is sparsely punctate and the remaining ridge rugoso-punc-
tate. Seutellum coarsely rugoso-punctate. Metanotum coarsely, sharply
and somewhat irregularly reticulate, with four basal areas, two median
longitudinal formed by coalescence of about three meshes and two outer
116

half smoky, a darker area near the hind margin and several milky hyaline
streaks in the submarginal and third discoidal cells; the second submavr-
ginal cell large and sharply pentangular. ;
First abdominal tergite rugoso-punctate to near the apex; the crenulate
ventral ridge strongly concave and with a large tooth near the apex
and another sharper one near the base. The area of the felt lines is
black. Segments II, 11J, [V and V with apical fringes of plumose hairs,
the first very dense, the last very thin.
This was one of the commonest species at Claremont, California.
Photopsis ingenuus n. sp.
Length 9 mm. In color almost the exact counterpart of P. pedatus ex-
cept paler, and with the whole thorax very much paler, almost yellowish.
In structure this form differs from pedatus in the following points:
The ocelli are about as near to each other as to the eyes. The mesopleural
transverse groove is scarcely evident, the depressed area is very sparsely
punctured, while but a small part of the longitudinal swollen portion is
sculptured and that indistinctly rugoso-punctate.

The present species differs by having the hairs of the head ochraceous,
the face below daik, and in other details which will be apparent in a
comparison of the descriptions.
4047 Chyphotes californicus n. sp.
Length 10.5 mm. Dark ferruginous, though not as dark as __ belfragei.
The pubescence is pale ochraceous and the legs and antennae are uniform
testaceous. Head entirely concolorous.
Head broadly rounded back of the eyes. Hind ocelli much nearer to
each other than to the eyes. lirst article of flagellum longer than second.
Metanotum with evenly distributed but widely separated punctures. The
pleurae have coarse but separated punctures, somewhat rugoso-punctate
on metapleurae and upper part of mesopleurae. Scutellum rugoso-pune-
tate. Metanotum with a distinet reticulum, the meshes subrectangular,
several times longer than wide and each with a large puncture within
near base. Wings with two submarginal cells, the second as large as the
first and receiving the two recurrent nervures*in the basal half; apical
half of the wings smoky, this area traversed by four radiating bands of
hyaline.
Petiole two-thirds as long as the nodose portion of the first abdominal
segment; the rugosities of the petiole above become strong transverse
ridges caudad. First and second tergites for most part thickly ‘‘spatter-
punctured ’’.*
Taken at Claremont California. This apparently finds its nearest rela-
tive in peninsulari from Lower California.
4044 Chyphotes similis n. sp.
Length. 7-8 mm. Rather dark ferruginous, quite thickly clothed with
sordid whitish pubescence; legs, scape and funicular joint of antennae
testaceous; abdomen darkened apically; head above antennae picéous.
_*. Covered with q-formed marks having a puncture within at the apex,
resembling a mark made by throwiag a pebble obliquely into a smooth sur-
face of soft mud.
118
Head narrowly rounded behind the eyes. Hind oeelli slightly nearer
to each other than to the eyes. First and second articles of flagellum of
about the same length, with extreme base of the first testaceous, the re-
mainder of the flagellum nearly concolorous with the body. Mesonotum
with shallow remote punctures. Scutellum medially almost smooth, rugo-
so-punctate around the sides.
Pro-and metapleurae rugoso-punctate, the mesopleurae anteriorly
remotely punctured, posteriorly smooth. Metanotum with a strong reti-
culum, but with meshes very irregular in size and shape, the surface
within the meshes minutely wrinkled. Wings with three submarginal
cells, the second about half the size of the: first, sub-ovate, and receiving
the two recurrent nervures, one near the base and one near the apex; the
third submarginal cell is subrectangular, a little wider above, and not
half the length of second; apical half of wings smoky, this area traversed
by four radiating bands of hyaline.
Petiole not quite as long as the nodose portion of the first abdominal
segment. First tergite and anterior portion of second, coarsely ‘‘spatter-
punctured’’, remotely so posteriorly on the second tergite; above on pe-
tiole and base of nodose portion, the punctures are arranged tranversely,
forming distinct ridges.
Taken at Claremont California. Apparently related to nubeculus of
Colorado in general characters, but it lacks entirely the ventral tufts
said to be most strikingly characteristic of that species,
4347 Chyphotes nevadensis n. sp.
Length 11 mm. Rather dark ferruginous, thickly clothed especially on
the abdomen with ochraceous pubescence; legs pale testaceous; anten-
nae honey-yellow; abdomen slightly darkened apically; head concolorous.
Head narrowly rounded behind the eyes. Hind ocelli about equally dis-
tant from each other and the eyes. First and second articles of the fla-
gellum of about the same length. Mesonotum with shallow, remote, large,
and ill-defined punctures. Scutellum uniformly covered with large, thickly
placed, but rather shallow punctures. Propleurae nearly smooth, meso-
pleurae anteriorly coarsely, evenly, rugoso-punctate. Metanotum with a
very strong, sharply defined reticulum which is quite uniform except in
a small area on the anterior border where it is finer and more dense; the
meshes are large, but very irregular in shape owing to the wavy nature
of the bounding ridges; the surface within the meshes is apparently
nearly smooth.
Wings with three submarginal cells, the second scarcely half the size
of the first, subtriangular and receiving the two recurrent nervures, one
just behind the middle, the other near the outer border; the third
submarginal cell subrectangular, a little wider above and more than half
the length of the second. Apical half of wings smoky, unusually dense in
front of the marginal cell, and with the smoky area traversed by four
radiating bands of hyaline.
DLS
Petiole two-thirds the length of the nodose portion of the first abdo-
minal segment; the nodose portion above and anterior part of second
tergite ‘‘spatter-punctured’’ much less strongly so on the latter.
Taken in King’s Canon, Ormsby county, Nevada. Also related to albi-
pes and nubeculus. From the latter it differs in lacking the ventral tufts
and in other characters. From the former it differs in not having the
‘¢first and second transverse cubital veins uniting above’’, a character
used by Fox in his synopsis. The various descriptions of albipes which
have been given are wholly insufficient as diagnoses in this genus. Ho-
wever, regardless of what the name albipes may possibly apply to, the
form described above will be easy to recognize by the characters I have
mentioned.

3450 Ancistrocerus sutteranus Sauss.
This species has been taken by Prof. Baker in Ormsby county, Nevada.
It seems to be a very variable species, particularly as regards the size
and shape of the black markings on the abdomen. In one example the
black mark is small and triangular; in another it is large, reaching from
the base to near the apex; the sides of the mark are roundly curved
inwardly. In one male the first abdominal segment is black except for a
mark on the sides at the apex.

below with some longitudinal fine striae. Frontal keel stout, a small ye-
llow spot on either side near the top. Clypeus as long as its greatest width,

I was at first inclined to refer this species to Symimorphus, but after
comparing it with the description of Nortonia given by Saussure (Syn.
Amer, Wasps. p. 1389) and by Dr. A. v. Schulthess (zeits. f. Hymen, u.
125
Dipterologie, 1904, 270-283) and with a male example of what I make
out to be WN. to/tect Sauss. from Mexico I am of the opinion that it is
2 Nortona My species is much smaller than any of the described spe-
cies of Nortonia In having a transverse keel on the first abdominal seg-
ment (as in Symmorphus) it agrees with MV. lugens Schult. from Peru.
The other species have no such suture.
3458 Polistes aurifer Sauss.
This species was described from California (Vespides II, 78) where it
is one of the commonest species, as it is now also in the Sandwich Islands.
It is a variable species, particularly as regards the amount of black on
the head, thorax, and abdomen. In extreme varieties the black on these
parts may be entirely absent, being replaced by rufous color, especially
in the workers. The malar space on the inner side is as long as the
sixth antennal segment; the clypeus in the middle above is transverse
with the sides straigth, obliquly narrowed; the apex in the middle projects
broadly roundly, its central part being wider than the lateral. The legs
also may want entirely the black colour, it being replaced, as on the
thorax, by rufous. Prof. Baker has taken the species at Claremont, Stan-
ford University, and Catalina Island, California. It seems rather remar-
kable that the species should have spread to the Sandwich Islands and
so far as is known to none of the West Indian Islands.
3444 Trielis xantiana Sauss.
Prof. Baker sends from Ormsby county, Nevada a female Trielis
which I can only refer to JT. xantiana Sauss. It has the thorax entirely
black; the head is black except for two marks between and touching the
antennae, a small one in the center of the face and the greater part of
the elypeus which are red; there are only six large yellow marks on the
abdomen, the pair on the first segment present on the typical form being
absent. The Ormsby county specimen may of course represent a distinct
species; but the material at my command does not enable me to form a
definite opinion on the matter. 7. aantiana is a Californian species, ef.
Saussure, Cat. Sp. Gen. Scolia, p. 149-151.

are more shining and less strongly punctured; there is a distinct longi-
tudinal furrow on the apical two-thirds of the meso-pleurae close to the
sternum. The scutellum is more strongly punctured than the mesonotum,
the furrows bounding it are distinct and deep. Ovipositor very short,
broad and white.

39938 Campsocryptus brevicornis sp. nov.
Ferruginous, the sutures of the thorax, more than the apical half of the
hind tibiae and the flagellum of the antennae, black; the seventh to ninth
joints of the flagellum yellowish beneath, the basal dark rufous. Wings
fuscous, tinged with violaceous; about the basal fourth of the fore
wings, a band of about the same length and of uniform width in the

from in front, long, not much narrowed below, the malar space as long
as the antennal scape. The apex of metanotum is only slightly depressed.
So far as I can make out from the descriptions, this species, while
closely allied to it, is distinct from C calipterus Say, e. g. that species
has the antennae ‘‘rather slender’’ and no pale annulus on them and the
metathorax has ‘‘a rather prominént lateral carina’’, ef. Cresson, Trans.
Amer. Ent. Soc. IV, 158.
PIMPLINAE
Ateleophadnus gen. nov.
Metanotum with two longitudinal keels in the center of the basal part
extending from the base to the top of the apical part, which is steeply
sloped. Clypeus clearly separated from the face, its apex transverse. Eyes

most smooth, roundly raised. Median segment thickly covered. whith white
pubescence, its apex with a steep slope, narrowly margined above and
without keels. Abdomen thickly covered with white pubescence, the
oblique depression deep and wide. Tegulae pale bright yellow. Transverse

sely punctured, the middle lobe more distinctly and strongly than the
lateral. Scutellum roundly convex, smooth, shining, its apical slope and
postseutellum strongly aciculated. Pro-and mesopleurae closely punetu-
red and more or less finely striated; the metapleurae finely rugosely pune-

HETEROPTERA
NOTES ON THE NYSIUS AND ORTHOLOMUS OF AMERICA
Cc. F. BAKER
Many years ago when first collecting Nysius —a genus of true bugs often
very injurious to certain cruciferous plants, beets, ete., but also oceu-
rring on many other plants—all attempts to arrange the species in my
collection according to the original descriptions were attended by unsa-
tisfactory and discouraging results. Had I been a collector of few spe-
cimens it might have been possible but I very early acquired the habit
of taking large series, and the farther I carried such work, the more
surely was the absolute necessity for it recognized. This is equally
true among all animals and plants, but Nysius has proven an unusually
pointed example of it. I have now before me twelve hundred spec-
imens belonging to my two collections, (one in National Museum and
one here in Cuba) which have been taken in Colorado, Arizona, New
México, Nevada, California, Nicaragua, Oregon, Washington, Alabama,
Cuba, and the Eastern United States. The variation in coloration among
the individuals of the different species is something altogether remar-
kable, the general pattern being much the same in all, apparent diffe-
rences in the majority of cases being due to varying intensity of pig-
mentation. This fact renders most of the original descriptions of American
species almost useless. In two late description (those of monticola and
ementitus), scarcely a single structural character is given, not even the
primary ones of amount of curvature of costal margin of corium, and
form of bucculae.
After careful studies in the comparative anatomy of the various
species were begun, many good characters were found which had not
been mentioned by any of the authors. Others which had been mentio-—
ned were found impracticable for use in classifying these large seriegayiila

endless intermediate conditions being of common occurrence.
matter of the determining of names, I am much indebted to
and to Mr. Heidemann, the determinations by the former o
his own species being of especial value. These determinations,
134
with copious collections from the various regions have enabled me to
recognize under older names several of the groups I take to be of speci-
fic value. But most of the older names should under no conditions be
used without careful comparison with the types—determinations from
the descriptions alone would usually be worthless. There is no doubt
but that many of the names represent merely color forms, and like-
wise some of the names now in use will doubtless be found exactly
equivalent to older names if the types were available for study. In
other collections which I have seen, the uttermost confusion has resulted
from the attempt at grouping according to the color descriptions. In
the same species there may be a very wide variation in this respect in
a lot taken together on the same food plant, but such a lot will usually
be found remarkably uniform in the finer structural details.
The status of the genus in America as to an evolutionary point of
view is apparently wholly opposed to that presented in Europe. In
America the species of typical Nysius, all belong to one general type
and present no wide subgeneric divergences, and possess a most remar-
kably high degree of individual variation in size and coloration. Some
of the subgenerie groups of the old genus Nysius, I regard as better
defined genera than many groups of the Lygaeidae commonly recogni-
zed as such. In America we have two very distinct groups of generic
value, Nysius and Ortholomus.

447 Nysius californicus Stal.
Among all the American species this is the most widely distinct by
great size—for a Nysivs—and its short and broad buceulae. It
abundant on the West Coast, from Oregon to Nicaragua at least. The
largest and palest forms—the most typical—are found in California and
Nevada; from this region towards the north, east, and south, the forms
become somewhat smaller and darker, such being of frequent occurrence
in Washington, Utah, and Colorado. Nothing is known to me of the
extension towards Idaho and Montana. Through Mexico and the Cen-
tral American countries the forms become not only smaller and darker,
but have the membrane strongly fuscous spotted like Ortholomus. The
more typical examples of this latter kind Dr. Uhler has determined for
me as his providus, which name can thus only be retained as a variety.
The only far eastern extension of the species occurs through Arizona
and Texas to Alabama, through which range the individuals become
smaller but the membrane remains nearly clear. To this southeastern
form I give the name alabamensis, it being the dominant variety in
Alabama. The specimen recorded by Dr. Uhler from Maryland perh-
aps belongs here. Dr. Uhler also records the species from Cuba, but in
extended collecting there I have found but one large species and that
belongs in Ortholomus.
444 Nysius angustatus Uhl.
This is the most abundant species in the Eastern United States,
extending northward into Canada, westward to Nevada, and south into
Mexico. I do not know that the larger more typical form passes the
southern Sierra Nevada. In Washington State is found a very dark
form which I have called variety niger All over the West, even
throughout California, occurs a small pale form with the structural
136
characters of the less common typical form and varying into it everyw-
here, and which Dr. Uhler first recognized under the name minutus.
Many years ago I sent some typical specimens of angustatus to Van
Duzee and they were determined by him as the Nysius thumi of Europe.
He also records thymi for the vicinity of Buffalo, but does not mention
angustatus though within the range of the latter as here understood.
I have had no authentic. European material of thymi and so cannot
work the matter out from the point of view of structure, However, lL
shall not be surprised to learn that angustatus is thymi.
1403 Nysius senecionis Schill.
On the West Coast of North America from Oregon through Nevada
and California to New Mexico, Mexico, and Lower California, there
occurs in abundance a medium sized, mostly pale testaceous Nysius
which presents remarkably distinctive characters of bucculae and other
parts. Dr. Uhler determined this for me as his strigosus and indepen-
dantly, Mr. Heidemann verified this determination. It is variable in
color though not nearly to the extent of angustatus. In coming to
compare it with the senecionis of Europe, I found myself unable to
separate the two on any constant appreciable characters. So we have
another case to add to the growing list of animals and plants common
to Europe and the west coast of America. Passing north into Oregon
individuals become more generally darker, as is true also in Mexico, but
these darker ones are also to be found among the lighter ones anywhere.
4410 Nysius coloradensis n. sp.
This is somewhat similar to a small californicus in size and general
appearance but differs widely from that species in structural charac-
ters. The bucculae are entirely different; the straight basal portion
of costal margin of corium extends about the length of the scutel before
it outeurves, whereas in californicus the basal straight portion is extre-
mely short, scarcely more than a fourth the length of the scutel. The
color is ashy or reddish-ashy with the general type of variable mar-
kings of californicus and some other species of Nysius and with a dense
silvery pubescence. The sides of the pronotum are unusually incurved;
the width across the eyes is to the anterior border is to the posterior
margin of pronotum as 9.5 is to 7.5 is to 11, the anterior margin of prono-
tum and length being about equal; membrane is nearly hyaline. In
the typical form the pubescence of pronotum is silvery white. Length
3.5 to 4.5 mm. I collected this species in large numbers in Colorado but
have not seen it elsewhere.
Occurring among individuals of this species are larger ones with a
length often of 5 mm., very much darker, the membrane smoky and
dark spotted, the pronotum more coarsely and irregularly punctured,
and pubescence more scant and ochraceous. I have called this form
variety grandis of the above species.
4373 Nysius ementitus Dist.
Here is placed a considerable series of specimens collected in Nicara-
: 137
gua and Cuba, evidently of a single species remarkably well characte-
rized by the unusual form of the costal margin of corium. It is a spe-
cies about the size and general appearance of angustutus and with bu-
eculae similar to coloradensis It has at various times been determined
for me as a species of Cymus, as Pelionelta tropicalis Dist., and finally
as Nysius monticola Dist., none of which it can by any possibility be.
It agrees closely with the illustrations of Nysius ementitus of Distant
and is doubtless that species. An adequate diagnosis was not presented
by Distant, who mentions none but color and other characters which
are common to other forms. I have no doubt but that it will be found
the same as some of the species previously described from the West
Indian Islands.

Genus Ortholomus Stal.
This group, first separated by Stal, is a perfectly valid genus, much
better founded than are numerous others’ of the family Lygaeidae The
costal margins of corium run straight caudad from the very base or
even converge posteriorly, and this character alone separates this genus
sharply from Nysius. Often considerable of the side margins of the
abdomen are exposed.
Whereas but a single species had been previously described from the
United States, several have been known to me for some time. One
species occurs in great abundance in Nicaragua and is also common in
Cuba. Dr. Uhler twice determined this for me as his inaequalis. This
is evidently the species referred to by Distant as Nysius spurcus. The
species N. spurcus was founded on characters drawn from specimens
collected in Tahiti, Rio Janeiro, and Honduras. The original description
is not at all diagnostic for species of this genus, and in large collections
of American material, [ believe that no sure determination could be
made from it. Perhaps the types are in existence. It seems more
than likely that several species have been confused under this name
and that the name must be reserved for the form from Tahiti only.
Indeed Stal himself seems to have come to this conclusién in the Enum.
Hemip. IV, 120, where he redescribes the species and mentions only
the Tahiti specimens. I believe that it would be only pure guesswork
and a source of confusién to use the name at present for any American
species. On the other hand we may be reasonably sure that this is the
naequalis of Uhler.
It seems strange that the longiceps of Stal, originally described
from Wisconsin has not been oftener collected. I have seen specimens
from Wisconsin, Indiana, Pennsylvania and Mexico, and was somewhat
surprised to find what is apparently the same thing, in the mountains
of Southern California.

HYMENOPTERA
THE BEE GENUS PASIPHAE IN NORTH AMERICA
BY C. F. BAKER
While in Central America I collected a number of species of
Prosopis (descriptions to appear soon) which were typical representat
ives of that genus in every way. Scattered through this collection
were a number of bees, very Prosopis-like, but possessing a truncated
and appendiculated marginal cell and otherwise corresponding to
Ashmead’s description of the genus Pasiphae, previously known only
from the southern Andean region. In Trans. Am. Ent. Soc. XXIX, p.
186, Cockerell says ‘‘Mr. Vachal remarks that this has a distinct
tibial pollen brush, and cannot go with the Prosopidae. It appears to
be a Colletid with only two submarginal cells.’’? The Prosopidae are
usually described almost without reservation, as ‘‘non-pubescent’’, a
statement that should be considerably modified. It is true that the
pubescence is reduced—thin and fine, but distinctly present over most
of the body in all of the American species I have seen. What the
naked eye or the simple lens does not show in this case, the compound
microscope will prove a clearly distinct feature. If the hind tibiae
of any Prosopis are carefully examined. they will be found usually
thickly covered with pubescence. Jn these Central American bees whic!)
I am calling Pasiphae, this pubescence is more pronounced than J have
found it in any Prosopis, and while it might possibly be called a
