JANUARY 9, 1908.

The 2 1 8th regular meeting was held at the Saengerbund
Hall, 314 C street, N. W. President Hopkins presided, and
there were present Messrs. Barber, Bishopp, Burgess, Burke,
Busck, Davis, Foster, Gahan, Hopkins, Jenne, Marsh, Patten,
W. J. Phillips, Popenoe, Quaintance, Sanders, Sasscer,
Schwarz, Townsend, Van Horn, Webster, and Weldon, mem-
bers, and Messrs. R. A. Cushman, W. S. Fisher, Paul Hay-
hurst, E. O. G. Kelly, and D. K. McMillan, visitors.

President Hopkins was nominated to represent the So-
ciety as a Vice-President of the Washington Academy of
Sciences. The following officers were elected for the year
1908: President, A. D. Hopkins, First Vice-President, Otto
Heidemann ; Second Vice-President, E. A. Schwarz ; Re-
cording Secretary, H. E. Burke; Corresponding Secretary,
J. G. Sanders ; Treasurer, J. D. Patten ; additional members
of the Executive Committee, Harrison G. Dyar, L. O.
Howard, and C. L. Marlatt.

Thanking the members of the Society for his reelection
Doctor Hopkins read and commented upon some portions of
the address of the first president, the late Dr. C. V. Riley.
Mr. Schwarz told of the difficulties of organization and the
hardships endured by the members for the first few years.
—Mr. Davis presented the Society with Bulletin 234 of the

1

2 ENTOMOLOGICAL SOCIETY

U. S. Geological Survey, which shows a number of interest-
ing views of the effects of the San Francisco earthquake and
fire. A vote of thanks was tendered Mr. Davis for this gift.

— Mr. Quaintance exhibited the larva and work of an unde-
termined species of apple miner. This larva forms very long,
serpentine mines under the skin of the apple, greatly dis-
figuring the latter for sale on fruit stands and similar places.
The injury permits of rapid evaporation of water in the fruit,
and wilting soon begins along the course of the mine, which
in a week or ten days may be very pronounced, rendering
fruit practically worthless for usual market purposes. While
the species has not been observed to be common, it might under
favorable conditions become a pest of importance. During
the present year apples thus injured were brought in from
the Ozark Mountains by Mr. E. L. Jenne, and specimens of
injured fruit were frequently found in a shipment of several
barrels of apples from Niagara County, New York. The
work of what is undoubtedly this same insect has been pre-
viously mentioned, and figured/1 though from the cast head-
skin found it was thought to belong to the genus Lithocolletis.
The larva exhibited was taken from the mine, and the insect
apparently winters in the larval condition. The adult has not
yet been reared. The work of what is probably the same
larva had been frequently noted on vigorous, growing shoots
of apple, such as nursery stock and water sprouts of old
trees. Specimens of twigs similarly injured have also been
received from Dr. H. T. Fernald, from Massachusetts. A
photograph taken by Mr. S. W. Foster, showing the mines
on apples, was also exhibited.

Doctor Hopkins remarked that he had seen a similar injury
in the skin of the orange at Nordhoff, Cal. The species caus-
ing it was said to be quite common there, and had inflicted
some damage.

Mr. Busck, on examining the apple-mining larva, said that
it belonged undoubtedly to the genus Marmara, Clemens. The
larva of one of the species of this genus makes similar pecu-
liar mines just under the epidermis on shoots of willow in

the eastern States and Mr. Busck bred other species with
identical habits on Arbutus from Seattle, Wash., and on
Opuntia from Texas.
— Professor Webster presented the following paper:

NOTE ON ADISTEMIA WATSONI WOLL.

[Coleoptera, Lathridiidae.]
By F. M. WEBSTER.

Very little seems to be known of the habits of this diminu-
tive beetle, and our literature is almost devoid of references
to the species. Mr. E. A. Schwarz was the first to record
its occurrence in this country, he having exhibited specimens
of it under the name Cartodere watsoni and made some re-
marks upon it at a meeting of the Entomological Society of
Washington held November 12, 1896.*

The statement was made that it had first been observed in
a sack of Lepidoptera from Alaska but that later it had oc-
curred quite commonly in old flower pots about the buildings
of the Department of Agriculture.

In his Revision of the Lathridiidas of Boreal America,b Mr.
H. C. Fall gave the American habitat as Washington, D. C.,
" in drugs," " in dust from feed store," and " among Alaskan
Lepidoptera." The author made it the sole representative of
his new genus Adistemia, and gave its distribution, outside
of America, as Canaries, Algeria, Cape of Good Hope, Portu-
gal, Venezuela, and Chile, and stated that the species was
described in 1871 from individuals taken on the interior walls
of a house in Funchal, Madeira.

While located at Morgantown, W. Va., Dr. A. D. Hopkins
began the breeding of several varieties of timothy. On be-
coming connected with the Bureau of Entomology he brought
from West Virginia some material which was turned over
to the Bureau of Plant Industry and was planted on the
experiment farm of the Department of Agriculture at Arling-
ton, Va. As this timothy offered exceptional advantages for the
study of Isosoma — with which some of it was badly infested—
in July, 1905, some of the stems of these different strains of
timothy were cut off close to the ground, brought in from
the experiment farm, and soon after placed in sacks of swiss

and securely tied. These sacks were kept in the same room
as several hundred others containing timothy and other grasses
not only from about Washington but from most of the States
east of the Rocky Mountains. They were not opened until
May 16, 1906, nearly ten months afterwards, when great
numbers of these beetles were found alive in the sacks from
Arlington, but in none of the others. It is difficult to see how
the beetles could have been introduced into these sacks in any
other way than with the hay, and had they gained access
thereto during the time the timothy was in storage it is diffi-
cult to see why they should not have entered other sacks also,
but among the hundreds of boxes of grains and grasses they
have not since been encountered.

It seems rather strange that we should, in our hundreds of
experiments in breeding insects from other points in this
immediate vicinity as well as from other States, have en-
countered this imported beetle but once, and then confined
exclusively to these varieties or strains of timothy.

Specimens of the adult were exhibited.

Mr. Schwarz said that this beetle feeds on the various
species of molds such as infest seed and herbarium specimens.
Although described first from Madeira, it is now cosmopolitan,
being found occasionally as a pest in herbaria. In regard to the
published statement that it has been found " among Alaskan
Lepidoptera " it should be noted that the baskets containing
the Lepidoptera (some geometrid) wrapped up in papers, were
detained at San Francisco for several weeks, and upon their
arrival at Washington many of them were found to be in-
fested by a mold, upon which the Adistemia was feeding.

Doctor Hopkins said that the food habit of these beetles was
particularly interesting in this case, because it probably ex-
plained the apparently peculiar facts noted by Professor
Webster. One of the varieties of timothy is known to be
infested with a destructive fungous disease, and it is prob-
ably from this variety that Professor Webster obtained his
specimens.

As an additional note, Doctor Hopkins stated that the
varieties of timothy are differently affected by both diseases
and insects, indicating that some are more susceptible to attack

OF WASHINGTON. 5

than others. Observations on insect enemies of forest trees
indicate that certain varieties of tree species are more resis-
tant to their enemies than other varieties of the same species.
These facts suggest that this is a subject which should re-
ceive detailed investigation in order that the practical value
of varietal selection in preventing damage from insects may
be determined.

— Mr. Burgess gave an interesting account of the Chicago
meeting of the Association of Economic Entomologists and of
the Entomological Society of America, and told of the found-
ing and purpose of the Journal of Economic Entomology.

— Mr. Barber reported that he had just returned from a two
months' trip to northeastern Wisconsin when the country was
covered with snow and ice. No attempts were made to collect
insects but a great deal of woodpecker work on the forest
trees had been noticed.

— Mr. Schwarz called attention to the note lately published
in Entomological Nezvs by Mr. G. C. Champion regarding the
synonymy of the pepper weevil (Anthonomus eugenii}, de-
scribed by Dr. Donaciano Cano y Alcacia, in La Naturaleza,
Volume II. No one could have been blamed for overlooking
this original description. Professor Herrera has lately drawn
attention to it in a small bulletin on the pepper weevil pub-
lished in Mexico City. Several specimens, apparently coming
from the original set, have just been received at the National
Museum from Dr. A. Duges. These completely lack the
asneous luster of the upper surface. A similar disappearance
of the aeneous luster is noticed in the type specimens of
Anthonomus aneolus Dietz, which are preserved in the U. S.
National Museum. The same change of color can be noticed
in a large lot of the pepper weevil collected two years ago at
San Antonio, Tex.

In this connection Mr. Schwarz said that in the spring
of 1907 he ascertained at San Antonio that in the early part
of the season large quantities of peppers were annually intro-
duced into the markets of San Antonio from Aguas Calientes,
Mexico, and adjoining places ; there is very little doubt, there-
fore, that Anthonomus eugenii was introduced into Texas.

6 ENTOMOLOGICAL SOCIETY

An allied species, Anthonomus mexicanus -GyftT, redescribed
by Linell as brevirostris, occurs in southern Texas at Browns-
ville and Victoria, but never infests peppers and is unques-
tionably specifically distinct from Anthonomus eugenii. At
present the pepper weevil has been reported as infesting only
the fruit of the pepper, but it will probably be found to in-
fest the blossoms just as the cotton boll weevil (Anthonomus
grandis Boh.) infests the cotton flowers and squares.

FEBRUARY 13, 1908.

The 2 1 Qth regular meeting was held at the Saengerbund
Hall, 314 C street, N. W. President Hopkins presided and
there were present Messrs. Barber, Barrett, Bishopp, Burgess,
Burke, Couden, Currie, Hall, Heidemann, Hooker, Hopkins,
Hunter, Jenne, Law ford, Marsh, Morgan, Patten, W. J.
Phillips, Piper, Popenoe, Schwarz, Van Horn, and Webb,
members, and Messrs. C. R. Ely, A. K. Fisher, E. O. G.
Kelly, and E. W. Nelson, visitors.

Mr. W. M. Giffard, President of the Board of Commis-
sioners of Agriculture and Forestry of Hawaii, was elected
a corresponding member of the Society, and Mr. E. J. Kraus,
of the Bureau of Entomology, U. S. Department of Agri-
culture, an active member.

The resignation of Prof. V. L. Kellogg from corresponding
membership was presented and accepted.

Mr. Patten reported that the Washington Academy of Sci-
ences had under consideration the publishing of a weekly
bulletin which would give notices of meetings, programs, and
other news of the various affiliated societies. Information
was desired as to the number of members, dues, publications,
etc., of the various societies. The corresponding secretary
was instructed to furnish the desired information for the
Entomological Society.

— Mr. Schwarz read the following note for Mr. Knab, who
was at that time in Mexico:

SWARMING OF A REDUVIID.

[Hemiptera-Heteroptera.]
By FREDERICK KNAB.

The swarming of the males of nemocerous Diptera is a
common and familiar phenomenon but I am not aware that
such a habit has often been recorded for the Hemiptera.
Late on the afternoon of January 4, 1908, when collecting
in the outskirts of Cordoba, Mexico, I came upon a swarm of
small insects, to all appearances Nemocera. It was at the
intersection of two paths through the coffee groves, where
the sun shone in obliquely. The insects were dancing in
the sunlight in the open space in the manner of male Nemo-
cera. They all faced in the same direction, just as do the
Nemocera, in response to currents of air. The swarm con-
sisted of several hundred individuals, weaving up and down
among each other. When captured the insects proved to be
a very small species of Reduviidae. Mr. Heidemann has de-
termined the species as Henicocephalus culicis Uhler. A little
later, at 4:30 p. m., at another intersection of paths, another
swarm of the same insects was found, dancing in the sun-
light. The swarm was larger than the first one and the in-
sects moved more rapidly. When the sun disappeared behind
some trees, a short time after, the swarm dispersed. I have
not yet determined if the individuals in the swarm are all
males, as is the case with the Nemocera.

Mr. Heidemann said that Henicocephalus (Enicocephalus')
was erected by Westwood in 1837, but has been described by
various other authors since then, under different names, on
account of differences in the head and thorax which are now
considered as only specific characters. The genus is cosmo-
politan, but specimens are not common. Twenty-five species
have been recorded. Six of these are from North America.
The genus was based on the species flauicollis from St. Vin-
cent, West Indies. He called attention to a note by Carlos
Berg in the Berliner Entomologische Zeitschrift, Volume
xxxvin, 1893, p. 362, entitled " Lebensweise von Henico-

8 ENTOMOLOGICAL SOCIETY

cephalus," where the swarming of this reduviid is recorded
both on the island of Ceylon and in the Argentine Republic.

Mr. Schwarz stated that many years ago he caught a num-
ber of specimens of Henico cephalus near Washington. These
were flying at or above the tips of some tall grasses at sunset.
The type specimens of H. culicis Uhler were found by him
among the debris under the reeds along the shore of Utah
Lake, Utah. Under the same conditions these insects were
found by Mr. Barber and himself along the warm creek at
Hot Springs, Yavapai County, Ariz.

Mr. Barber said that he found either the same or another
species under the bark of a dead oak in Tennessee and also,
under the same conditions, in Dorchester County, Maryland.
In both cases there were a pair of adults and a number of
various-sized larvae.

— Mr. Hooker presented two short notes, as follows:

INJURY TO OAK FORESTS IN TEXAS BY HETEROCAMPA

MANTEO DOUBLEDAY.

[Lepidoptera, Notodontidae.]
By W. A. HOOKER.

In September and October, 1904, while in Lamar County,
which borders upon the Red River in Texas, I observed a
widespread injury to the oaks which make up a great part
of the forest in this section. This injury was found to be
due to what Professor Comstock has called the variable oak-
leaf caterpillar, Heterocampa manteo. The injury was espe-
cially noticeable upon the post oaks, which appeared as if a
fire had swept through them. It extended from Paris to the
Red River some 15 miles to the North, and newspaper reports
showed it to extend into Red River County to the East.

I have waited, hoping to visit that locality again, but as I
have not had the opportunity, I wish to place this observa-
tion on record. In looking up the literature upon this insect
I find that Professor Comstock in his report as Entomologist
of the Department of Agriculture for 1880, page 259, states
that during the season of 1880 a great amount of damage was
done in at least two counties of Arkansas (Garland and Saline)

OF WASHINGTON.

by the destruction of the foliage of the oak forests by this
insect. This seems to be about the only report as to any
extensive injury.

In passing through the forest near Paris, Tex., in 1904 the
droppings, as they fell upon the dry leaves, reminded one of
a heavy downpour. Large numbers of Calosoma scrutator
were present, as many as a half dozen often being found
beneath a single oak, and several individuals were observed
coming down the tree trunks with caterpillars in their mandi-
bles. An occasional Calosoma calidum was also noticed.

Packard, in his Monograph of the Bombycine Moths, Vol. I,
page 224, gives the synonymy of this species and Doctor Dyar
shows the differences between the larvae of Cecrita bilineata
Packard and Heterocampa manteo in Entomological News
for 1893, pages 262-263.

AN OBSERVATION ON AGAPOSTEMON MELLIVENTRIS

CRESSON.

[Hymenoptera, Apoidea.]
By W. A. HOOKER.

While at Eagle Pass, Tex., with Mr. J. D. Mitchell in Oc-
tober of last year (1907), I observed a peculiar condition in
a species of bee which Mr. Crawford has determined as Aga-
postemon melliventris Cress. Males and females were found
in large numbers on the blossoms of a species of rosinweed
(Silphium). When collected they would fall or roll into the
cyanide jar without attempting to fly, and if shaken off they
would fly sluggishly to the ground.

Mr. Crawford informs me that the species of the genera
Agapostemon and Augochlora are among the most easily dis-
turbed of the bees and that they usually take flight upon
approach. He has collected this species in Texas and found
it to take flight as readily as others of the genus. It is
a southwestern species, found as far north as Colorado, and
originally described from the Territory of Nevada.

This condition could hardly have been due to cold, as the
day was mild, though quite windy, and the sun shone through-
out the afternoon while the collections were being made. It
may possibly have been due to some effect which the nectar of
this particular plant has upon the bees.

10 ENTOMOLOGICAL SOCIETY

— Mr. Hooker also stated that while at Eagle Pass, Tex.,
in October, 1907, he collected three species of scales, Cero-
plastes cistudiformis Towns. & Ckll., Coccus hesperidum L.,
and Aulacaspis sp., on mistletoe (Phoradendron flavescens}
growing on mesquite in the Military Reservation at that
place. Ceroplastes cistudiformis, according to Mrs. Fernald's
Catalogue of the Coccidae of the World, has been reported
from Mexico and California. The mistletoe furnishes a new
food plant for the species.

Doctor Hopkins stated that the common references to the
destruction of hardwood timber by defoliating insects were
usually misleading. They give the impression that the trees
are killed, when in reality it is only the foliage that is de-
stroyed. His observations indicated that the first defolia-
tion, or even a second or third annual defoliation, did not
perceptibly affect the vitality of some species of deciduous
trees, citing as an example a number of young pin oaks
(Quercus palustris) on his farm in West Virginia, which
had been repeatedly defoliated by Lachnosterna in May during
the past ten years, and frequently some of them a second time
the same season by Anisota senatoria Hbn., yet their vitality
was not impaired, as evidenced by the rapid increase in size and
their vigorous condition at the present time. The defoliation
of other species of deciduous trees at a critical period in their
life activity may prove disastrous, as shown by many of the wil-
lows along the Potomac, in the vicinity of Plummers Island,
Maryland, which have died, evidently as the direct result of
complete defoliation by sawfly larvae in August. About the
year 1892, thousands of locust trees (Robinia pseud-acacia)
died in West Virginia. After about the third successive year
of destruction of the leaves in July and August by the locust
leaf-beetle (Odontota dorsalis Thumb.) it was noticed that
young sprouts and new leaves appeared on the trees late in
the fall. This was followed by severe cold, 15° to 25° below
zero, in December and January, and it was thought that the
direct cause of death of the trees was due to the freezing
following the abnormal condition of new growth as the re-
sult of defoliation.

OF WASHINGTON. 11

Doctor Hopkins's observations indicated that one or two
complete defoliations of coniferous trees usually resulted in
their death, excepting the larch, which succumbs after the
second or third defoliation.

Records of depredations by the " Nonne " moth (Liparis
wonacha L.) in the coniferous forests of Europe indicate that
a vast amount of timber has died at different times during the
past four hundred years as the result of defoliation and sub-
sequent attacks by barkbeetles. Doctor Hopkins stated that
his observations in this country indicate that coniferous trees
defoliated by insects or injured by diseases of the foliage
are not as attractive to barkbeetles and bark-boring insects
as are those injured by lightning, deadened, or felled with
the axe, or broken by storm.

Mr. Burgess said that defoliation in the fall often causes
serious injury to nursery stock and larger fruit trees, for it
causes the buds to start and thus results in winter killing.
Mr. Hunter thought that the climatic conditions which follow
the defoliation might have a great deal to do with its effects.
Mr. Piper questioned the statement that defoliation is always
fatal to coniferous trees and said that many yellow pine trees
in eastern Washington and Idaho had recovered after com-
plete defoliation by the pine butterfly (Neophasia menapia
Feld.). Mr. Webb said he had observed this same condition
in Idaho.

— Mr. W. J. Phillips read the following paper:

NOTES ON TOXOPTERA GRAMINUM AND PARTHENO-
GENESIS OF ONE OF ITS PARASITES.

By W. J. PHILLIPS.

Observations were made on the spring grain-aphis (To.vop-
tera graminum Rond.) at Richmond, Ind., from June, 1907,
to December n, 1907. During this period a number of inter-
esting things came to light.

It was observed that Toxoptera molts but four times ; and,
even under the most favorable conditions, the period between

however, as it does for different individuals. The following

From the above data it seems that there is no fixed period
for the different molts or the appearance of the first young.

It was found that a temperature of 30° F. or below had
the effect of lengthening the period between molts; also, of
lengthening the period between generations. At the ordinary
summer temperature, a generation is produced in from 6 to
ii days; in autumn the period varies from 14 to 48 days. A
temperature of 8° F. does not kill the insects, but as soon as
the temperature rises to from 40° to 50° F. they go on re-
producing.

THE EGG-LAYING FORM.

Early in October winged males and egg-laying females
appeared on blue-grass in the vicinity of Richmond, Ind.
They were still abroad the nth of December. Numbers were
dissected and found to contain from 3 to 5 eggs. In Decem-
ber, while dissecting females breeding on blue-grass in an out-
of-door cage, an individual was found containing 2 embryonic
larvae and 2 perfectly developed eggs. This is the second
time this singular phenomenon has come under my observation.

BIRTH OF YOUNG.

Observations were made on the manner of birth of the
young. Adult Toxoptera were taken from out of doors into
a warm room and watched under a compound microscope.
The young appeared to be enclosed in a delicate, membranous
sac, from which they would free themselves, as a rule, before
being dropped from the body of the mother. In several
instances, however, they were dropped before having ruptured
the sac at any point. In the latter case, they looked like
perfectly developed pupae before emerging from their cases.
When dropped in this manner they seemed to expand and
contract gently until the sac ruptured at the cephalic extremity.
By this gentle expansion and contraction they would finally
free themselves, leaving the sac crumpled and folded upon
itself.

PARTHENOGENESIS OF LYSIPHLEBUS TRITICI.

From observations made at intervals during the summer
it appeared that these parasites were parthenogenetic. In No-
vember experiments were begun in proving this point. These
observations were made indoors at a temperature of 50° F.
to 60° F. Seven virgin females were secured, each for a
separate experiment, and placed in separate cages with Tox-
optera known to be unparasitized. Each of the parasites
began ovipositing in the Toxoptera in a few minutes. After
one of the virgin females had ceased ovipositing in the Tox-
optera she was removed from that cage and confined with a
male, allowed to mate, and then transferred to another cage
containing unparasitized Toxoptera. She soon began ovi-
positing in them. All these parent parasites were preserved.

Viviparous Toxoptera were used in the preceding experi-
ment. Lysiphlebus, however, parasitizes the oviparous indi-
viduals also.

December 8, adult parasites issued from all the parasitized
Toxoptera. Offspring of virgin females were males ; off-
spring from the fertile female had predominance of females.

— Mr. Barber exhibited male, female, larvae, and photo-
micrographs of Ignotus anigmaticus Slosson, which had been
received from Mr. Blanchard and Mr. Joutel. He said that
Mr. Blanchard had a fine series of drawings made by Mr.
Joutel, which he hoped would soon be published. Mr.
Schwarz stated that Ignotus is the first instance in the clavi-
corn series of Coleoptera where there are neither elytra nor
wings in the female.

— Mr. Couden exhibited a specimen of the peculiar larva first
described and figured by Mr. Barber in Volume vn, pages
117-121 of the PROCEEDINGS of this Society. Mr. Couden said
that this specimen was found in the collection of the U. S.
Department of Agriculture. It was sent in from California
by Mr. Coquillett a number of years ago. When found, it
bore the label " Nitidulid larva." Mr. Schwarz said that he
did not believe that it was a nitidulid. Mr. Barber exhibited
photographs and slides of his specimens.

— Mr. Heidemann exhibited some Hemiptera-Heteroptera
sent him by Mr. J. R. de la Torre Bueno from New York. The
specimens were not in good condition for examination, but
they appear close to the European species Stygnocoris rusti-
cus Fallen, and probably belong to that species. The genus
Stygnocoris has not been recorded from North America
before.

Ainslie :

TETRASTICHUS AS A PARASITE ON POLYGNOTUS.

By C. N. AINSLIE.

[Hymenoptera.]

The exact position of Tetrastichus in the field of parasitism
has been the occasion of much discussion among students of
insect economy. Certain investigators have claimed it to be
in every case a secondary parasite, while others, with a dif-
ferent viewpoint, insist that, in the case of the Hessian fly at
least, it is a primary enemy. Two species of Tetrastichus,

OF WASHINGTON.

15

productus and carinatus, are listed by Professor Osborn in
Bulletin 16, new series, Division of Entomology, U. S. De-
partment of Agriculture, as parasitic on Polygnotus — that
minute proctotrypid whose untiring hostility to the Hessian
fly renders it an important factor in keeping the world's table
supplied with bread.

Evidence in support of either contention is difficult to se-
cure. Individuals reared from infested material prove as
much for one side as for the other, since their presence is
mainly inferential and their mission may be interpreted as the
student may see fit. Clearly the only satisfactory solution of
the problem, is to see the Tetrastichus at work, if possible, and
discover what it is doing. By a fortunate circumstance this
has actually happened in at least one very
interesting instance.

During the month of April, 1907, a
large number of wheat plants containing
Hessian fly larvae known to be infested
with Polygnotus was transferred from
Marion, Pa., to a field of wheat on the
battlefield of Antietam near Sharpsburg,
Md., where the fly was prevalent and
where no Polygnotus had previously
been found.

On July 8 of the same year this field
was visited by Prof. F. M. Webster and
Mr. E. G. Kelly, and a quantity of ripen-
ing straw containing numerous flaxseeds
was gathered and sent to Washington.
Examination showed that a large per-
centage of these flaxseeds contained
Polygnotus, which seems to indicate that
the imported parasites began operations
as soon as they emerged from the Marion
material in Maryland.

This infested straw, collected in July, remained dry in the
office during the summer, and apparently no adults issued
therefrom. About Nov. 15 I removed a number of the Hes-
sian fly puparia, cleared them in carbol-xylol, and mounted
them in balsam. The pupa case of the fly is quite dense in
its structure, but the mounts gradually cleared in the balsam
until the contents of the puparia became distinctly visible.
The accompanying drawing (fig. 2) is a fair representa-
tion of the colony of Polygnotus that was in possession in
many of these flaxseeds, although the number of included

gnotus, and a hyperpara-
site, Tetrastichus sp.

ENTOMOLOGICAL SOCIETY

adults varied from 3 to 12 or possibly more. Doctor Howard
has called attention to the position of these parasites, heading,
as may be seen in the illustration, toward the nearest end of

the pupa case. This rule has some ex-
ceptions, but seems to hold good in the
majority of those examined. Many of
these Polygnotus were living when these
mounts were made, but those that re-
mained in the straw all died before
New Year's, possibly because of lack of
moisture or on account of abnormal con-
ditions generally.

Figure I illustrates a most unique ex-
ample of hyperparasitism of the Hessian
fly discovered in one of these mounts
after they had cleared. Two perfect
adult Polygnotus are to be seen within
the pupa case, while beside them, lying
in what is clearly a Polygnotus cell, is an
adult Tetrastichus. The cells occupied
by the Polygnotus are clear and free
from debris, exhibiting only the black
residue of matter remaining from the
larval state. In the other cell with its
strange guest, besides the same black
residuum is a mass of debris or floccu-
lent matter, extremely suggestive of a
previous tenant.
It is of course impossible to determine the species of this
Tetrastichus nor can it be known if it was introduced with the
Polygnotus from Pennsylvania, or if it made the attack from
ground already occupied by it. In any event it plainly oper-
ates to the disadvantage of the farmer by lessening the army
of Polygnotus, thus befriending the Hessian fly.

NOTE ON THE OCCURRENCE OF CAMPYLOMYZA.
SCUTELLATA SAY.

[Diptera, Cecidomyiidae.]
By C. N. AlNSLlE.

I desire to record the discovery of a new habitat of a hitherto
rare dipteron, Campylomyza scutellata.

While at Jefferson, Ohio, October 10, 1907, my attention was

OF WASHINGTON. 17

attracted by swarms of a minute fly of a species that I had
never noticed before. These flies abounded on certain wooden
uprights in a clover and timothy meadow. They were exceed-
ingly active and when disturbed would move to a new location
and alight, but were constantly in motion while on the wood,
running about in an apparently aimless manner.

A sweep of the net captured hundreds of them from the
myriads present. The species was determined by Mr. D. W.
Coquillett, who informed me that it had been reported from
Missouri, but that no examples had been placed in the National
Museum prior to those collected by myself. It may be of wide
distribution, but its small size would prevent its being noticed
unless occurring in the numbers I observed in Ohio.

Nothing seems to be known of its life history.

TENACITY OF LIFE IN EVANIA URBANA BRADLEY.

[Hymenoptera, Evaniidse.]
By C. N. AlNSLlE.

An interesting instance of tenacity of life came under my
observation in Washington during September, 1907.

An individual of that peculiar species of Hymenoptera,
Evania urbana, while running about the office floor at 904
B street, S. W., met with the serious misfortune of losing
its head by an accidental and wholly unintended movement of
my foot. The catastrophe broke the neck of the insect neatly
without at all bruising or crushing either the head or body.
To help the poor fellow all I could I attached the completely
severed head to the body by means of shellac, and laid the
patient aside in a vial to see if the operation would prove
successful. The decapitation occurred about 10 o'clock in the
forenoon. That afternoon at 4 130 o'clock the insect was still
alive, the feet were moving, and the antennae waving with some
animation, but there was no attempt at locomotion.

Next morning the body was apparently lifeless, for I could
detect no motion of the tarsi, but there was still a slight motion
of the antennae, showing that the head retained its vitality
longer than the body. About 10:30 I could see no movement,
and it is probable that life became extinct about twenty-four
hours after the tragedy took place. I have often observed an
injured insect live longer than this one, but never one from
which the head had been completely removed.

18 ENTOMOLOGICAL SOCIETY

— Mr. Burke exhibited specimens of Boros unicolor Say,
a beetle belonging to the family Pythidae, which had been found
by Mr. R. W. Van Horn on January 21, 1908, under the dead
bark of Pinus virginiana at Glen Echo, Md. Mr. Schwarz
said that this species belongs to the Boreal fauna and so its
occurrence in the locality is only temporary. It probably comes
down the Potomac River or by railroad with logs. Mr. Barber
disagreed with this, because he had found the species several
times at quite a distance from the river and railroads.

— Dr. Hopkins presented a note on a scolytid beetle, Ips
(Tomicus} decretus Eichh., living in bark saturated with sea
water, stating that while at Virginia Beach, Va., last November
he found two pine logs on the sea beach which had been cast
up by the waves. The bark on both of them was only partially
dead and was found to be infested with broods of the bark-
beetles. One log was found on November 20, which had cer-
tainly been cast up within a day or two ; the other, found on
the 28th, had been cast up during a storm on the 24th, or at
least it was known that it had not been on the beach in that
vicinity at any time within ten days previous to that date. The
bark of both logs was thoroughly saturated with sea water
when found, and repeatedly soaked by the tides. All stages
of the insect were found in large numbers in the bark, and
the matured adults were emerging and crawling about on
the surface of the wood and bark. It was very evident that
these logs had been floating about in the sea for some time be-
fore they were cast up by the waves and that the broods of the
barkbeetles had been able to survive. It is evident that the
parent beetles entered the bark and deposited their eggs before
the logs got into the water, or possibly after they had been in
the water and at a time when they were temporarily on the
beach, since it is not likely that the beetles could enter the bark
while the logs were in the water. When it is considered that
it requires about thirty days for the broods of the barkbeetles
to develop, it is evident that this or a longer period had elapsed
since the logs were first infested. This power of a barkbeetle
to live in water-soaked drift logs is of interest in showing their
power of resistance to such conditions and how a species may

OF WASHINGTON. 19

be thus distributed. The barkbeetle comes very close to a
common European species, Tomicus sutiiralis Gyll., in fact ap-
pears to be more closely allied to it than to the common North
American species, Tomicus calatus Eichh.

Mr. Schwarz said that he had observed a similar habit of
Tomicus ccelatus at Old Point Comfort, Va. Four or five
years after the construction of the Government pier, broods of
this species were found under the bark of piling which were
subject to the salt spray.

Mr. Burke remarked that he had observed at Kent, Wash.,
that Douglas spruce piling which had been in the salt water
for several months was attacked by the scolytid Gnathotrichus
sp. in preference to that freshly cut.

— The following paper was presented for publication :

NEW SPECIES OF BALANINUS, WITH NOTES.

[Coleoptera, Curculionidse.]
By F. H. CHITTENDEN.

While studying the species of this genus in the preparation
of certain papers on the nut weevils for publication by the
United States Department of Agriculture, the writer experi-
enced considerable difficulty in correlating the sexes of several
forms. This difficulty increased by the accumulation of
specimens received from correspondents who mistook the
beetles for the boll weevil, as many of these did not agree with
named specimens in the National Museum or with published
descriptions. Accordingly the writer undertook to obtain
acorns from various sources, especially from the South, for
rearing. Mr. F. E. Brooks, who is also interested in the
biological study of the genus, at the writer's suggestion pre-
served males and females found in copulation, and the receipt
of sets of specimens from him, collected at French Creek,
W. Va., has greatly facilitated the completion of this paper,
begun some time ago. It should, perhaps, not be necessary to
state that of all described forms of Balaninus two feed on
chestnut, one on hickory and pecan, and one on hazel, the
remainder being, so far as we know, all acorn feeders. In a
paper published in 1897 Col. T. L. Caseya remarked that " the

species having short beaks in both sexes are numerous within
the borders of the United States and have only been super-
ficially elaborated thus far." In the paper cited 9 additional
species are described. The present paper describes 5, and it
seems probable, as surmised by Colonel Casey, that there are
still more awaiting description ; in fact, it was only for lack
of sufficient material that some of the forms mentioned in the
present paper were not described earlier.

Type. — No. 11996, U. S. National Museum.

The above description was drawn from a good series from
Ithaca, N. Y. Specimens from other localities exhibit con-
siderable variation as regards the rostral structure, which is
seldom so abruptly recurved at the apex as in the type. This
species is known in collections generally as " uniformis " and
is sometimes labelled " obtusus."

Observed by the writer in copula and in great numbers on
two trees of Quercus alba, always in company with Balaninus
quercus, at Ithaca, N. Y., September 1-8. Taken by Dr.
A. D. Hopkins in West Virginia on yellow oak, Quercus
velutina (tinctoria). It also infests the acorns of other oaks,
including most biennials.

Balaninus baculi var. curtus, n. var.

Series from Texas and Florida, including reared material
from Boerne, Tex., differ considerably from the northern
forms, appearing to be deserving of a varietal name, partic-
ularly as they breed true to their own type. This form differs
from typical baculi in its smaller size, vyider elytra, and paler
colored scales. The rostrum is proportionately and very dis-
tinctly shorter and more slender and not so abruptly recurved
at the apex, frequently being nearly straight.

Length, 5.7-7.0 mm. ; width, 2.7-3.2 mm. ; rostrum, 5 3.0-
3.2 mm. ; <$ 2.5-2.7 mm.

Balaninus uniformis Leconte.

Balaninus occidentis Casey, Ann. N. Y. Ac. Sci., ix, 1897, pp. 658-659.

Comparison of all available material from California — in-
cluding specimens of both sexes from Colonel Casey's type
localities, Santa Cruz and Sonoma counties, Cal., and specimens
identified by Mr Frederick Blanchard by comparison with
Leconte's types at Cambridge — with the description cited
leaves practically no doubt that occidentis is a synonym of
uniformis.

In the National Museum collection there are also specimens
from Los Angeles, Mt. Wilson, Catalina Island, Humboldt
County, Palo Alto, and Dunsmuir, Cal. There is also a. small
series collected by Messrs. Hubbard and Schwarz at American
Fork, Utah, June 23.

It might be added that this species is clothed with ochreous
scales, not gray as with bacilli, previously described ; also, that
it is the only species of its genus recognized from the Pacific
Coast States.

Balaninus q.-griseae, n. sp.

Moderately robust, piceous, somewhat depressed; rostrum, antennae,
and legs rufous; vestiture of dorsum yellowish brown, hairy, of lower
surface composed of elongate hair-like pale-gray scales; elytra with
large, very variable, subtransverse pale fasciae, appearing gray by
contrast with the darker brown general color.

Head with a distinct, smooth interocular line. Rostrum $ three-
fifths as long as body, slender, of uniform width, slightly elevated at
extreme base, moderately arcuate, rather more so toward apex ; antennas
inserted behind basal fourth, scape short, about as long as the first
two funicular joints, first funicular long, second and third subequal.
Thorax a little wider than long, basal half with sides parallel. Elytra
moderately narrowed toward apex; strise deep and wide, intervals
rather strongly convex. Legs of moderate length, femora of posterior
pair not extending beyond elytra, tooth large and conspicuous. Fifth
ventral segment of $ strongly impressed in nearly the middle third.

Male. — Rostrum a little less than half as long as body, curvature
similar to ?; stout, much enlarged at base, scales covering nearly half
from base to antennal insertion ; antennae inserted at or considerably
behind middle; scape shorter than first three funicular joints. Last
ventral segment and pygidium with yellow hairs forming a tuft extend-
ing beyond elytra.

Type. — No. 11553, U. S. National Museum.

In collections this species has been placed with nasicus and
quercus, from both of which it differs by the shorter and
thicker rostrum, with its enlarged apical extremity in the male.
From the former also it can be distinguished by the shorter
femora and more distinctly spotted character of the elytral
vestiture, nasicus being marmorate. Another important char-
acter by which it may be separated from quercus is in the male,
in which the abdomen is not produced into an open tube of
hairs.

A large series shows considerable variation from the type
as regards length of rostrum and scape and color. Pale indi-
viduals are frequently found as with other species.

This species has been reared in abundance by the writer
from acorns of Quercus bicolor, rclntina, and pednnciilata at
Washington, D. C., collected by various associates, and from
Quercus alba collected by Mr. F. C. Pratt at Colemanville, Pa.
Mr. Brooks writes that he has taken it abundantly at French
Creek, W. Va., on Q. alba also, and, rarely, on Q. priuiis.

26 ENTOMOLOGICAL SOCIETY

It is somewhat singular that the species should have escaped
notice for so long a period, since it is represented in most of
the extensive collections of Coleoptera.

Balaninus orthorhynchus, n. sp.

Body slender, piceous or rufous, antennae and base of rostrum more
distinctly rufous. Vestiture dense, composed of pale yellowish squa-
mules, finer on dorsal, much shorter and wider on lower surface.
Elytra wide at base, strongly acuminate to apex; striae of moderate
width, with few scales; vestiture variable, nearly uniformly yellow
or with pale brown spots of variable size.

Rostrum $ nearly straight, arcuate at extreme apex, of about the
same length as the body and of uniform width ; antennae $ inserted near
base at about the basal fifth, scape about the same length as the first
two funicular joints. Fifth ventral segment subtriangular, strongly
concave in medial third, slightly tufted at extreme apex. Legs long.
Femora feebly clavate, posterior teeth small, acutely produced distally,
reentrant angles rounded.

Male. — Rostrum moderately arcuate, very short, scarcely half as long
as the body; antennae inserted slightly behind the middle. Fifth
ventral segment with a small, partially denuded medial area in apical
half.

Dimensions. — Length, 6.2-7.5 mm.; width, 2.8-3.2 mm.; rostrum,
? 6.5-7.0 mm., c? 3.0 mm.

Habitat. — French Creek, W. Va., collected by Mr. Fred. E.
Brooks on Quercus rubra and coccinea, and other biennial oaks ;
Texas (Coll. C. V. Riley) ; 4 females, 2 males.

Type. — No. 11556, U. S. National Museum.

The rostrum of the female is more nearly straight than in
any other long-beaked species of the genus, which character
alone will distinguish it. It has otherwise somewhat the ap-
pearance of a small B. quercus, with which it is evidently
nearly related.

Balaninus caseyi, n. nom.

Balaninus brevirostris Casey, Ann. N. Y. Ac. Sci., ix, 1897, pp. 662,
663.

Colonel Casey's name is preoccupied by Pascoe's B. breviros-
tris from Landana, Congo, South Africa (Jour. Linn. Soc.

Zool., Vol. xix, p. 331, 1886).

ON THE CLASSIFICATION OF THE CORYDALIN^E, WITH
DESCRIPTION OF A NEW SPECIES.

[Neuroptera, Sialidse.]
By NATHAN BANKS.

While examining the new species described below I became
interested in some points of venation which distinguished it
from our common species of Chanliodes. This led to an in-
vestigation of all the forms available, with the result of finding
several new characters for the distinction of the various genera.

Neohermes humeralis, n. sp.

Jet black ; head from middle of eyes back to prothorax bright" red-
dish, except a blackish spot around ocelli ; extreme base of wings
bright yellowish, rest of wings blackish, the costal area to pterostigma
paler; venation black; no other markings. Head rather long and
narrow; antennae at base but little if any farther apart than are the
posterior ocelli, slightly serrate beneath in male; posterior ocelli fully
three times their diameter apart; vertex with about three or four elon-
gate elevated areas each side; pronotum distinctly longer than broad,
sides parallel. Wings moderately slender; cells of costal area mostly
longer on the subcosta than broad ; first fork of cubitus starting away at
a very acute angle; anal vein with two branches, both strongly genicu-
late, the two anal cells subequal in length, the lower giving off two
veins, the upper without any; no cross-vein between first branch of anal
vein and last branch from anal cell.

Expanse, 76 mm.

Two specimens from Santiago, Chile (M. J. Rivera). Pro-
fessor Rivera kindly gave me also two specimens of Chaidiodes
cinerascens Blanchard.

A comparison of these with our United States species has
led me to propose other characters than those now in use for
the separation of the various genera allied to Chauliodes
and Corydalis. One of the principal distinctions formerly in
use was the comparative abundance of cross-veins in the wings ;
this was scarcely usable, as there is a great amount of variation
in this matter. The presence of the tooth on the side of the
head behind the eyes is more easily used, yet one can hardly
consider it a character of great value. The venation of the
various genera is extremely similar, except in the anal region.
In most of the forms the anal vein forks but once, but in these
two Chilean species, in several of our native species, and in
those species placed by Doctor van der Weele in the genera

28 ENTOMOLOGICAL SOCIETY

Hermes and Protohermes the anal vein has two forks. As
this point is readily observed I shall consider it the first in
distinguishing genera.

The forking of the branches of the median vein is very
useful, as pointed out by Mr. Davis ;a but in some specimens
the fork is very close to the margin and only in one branch.
There is another point in venation which is very suggestive ;
that is the number of cross-veins between the radius and radial
sector. All the American forms have but three (in one wing
of one Neuromus hieroglyphica I find four), while in the
Oriental forms there are five, six, or more, perhaps occasionally
but four, except in the true Chauliodes (C. japonicus, C.
diversus) which have but three cross-veins. One can not
apply this point as of prime importance since it would widely
separate otherwise closely related forms, as for example the
Oriental and American Corydalis and Nenromus.

The genera I recognize may be tabulated as follows :

TABLE OF GENERA OF CORYDALIN^.

1. Anal vein of fore-wings with but one fork 4

Anal vein with two forks ; anal cells subequal in length ; the lower

with two branches, the upper with none 2

2. A cross-vein between the first branch from the anal vein and the

last branch from the anal cell; costal cells broader than long; an-
tennae much nearer eyes than ocelli; branches of median vein
forked; more than three cross-veins from radial sector to radius. .3
No such cross-vein present ; antennae about as near ocelli as to eyes ;
cells of costal area about as long as broad; branches of median
vein not forked, three cross-veins from radial sector to radius.

Neohermcs.

3. Ocelli small, the median twice its diameter or more from the

others Hermes.

Ocelli large, the median about its diameter or less from the others.

Protohermes.

4. A distinct tooth on margin of head behind each eye; antennae nearer

to eyes than to ocelli, last tarsal joint about as long as basal; at
least one branch of median vein forked; pronotum longer than

broad ; upper anal cell with one branch 5

No such tooth on margin of head behind each eye; antennae as near
mid-ocellus as to eyes; branches of median vein simple; pronotum
usually as broad as long; radial sector connected to radius by
only three cross-veins, upper anal cell with 2 veins or one forked
vein 6

" Bui. 68, N. Y. State Museum, p. 452, 1903.

OF WASHINGTON. 29

5. Labrum deflected; clypeal margin toothed; cross-veins in apical part

of wing numerous Corydalis.

Labrum horizontal, partly covering mandibles; clypeal margin not
so distinctly toothed; cross-veins in apical part of wing less
numerous Neuromas.

6. Anterior ocellus small, round, more than twice its diameter from the

posterior ocelli ; costal cells about as long as broad ; black species.

Nigronia.

Anterior ocellus large, transverse, not twice its long diameter from
the others; gray, mottled species. Chauliodes.

Neohermes, n. gen.

This new genus is proposed for such species as have the anal
vein with two forks, the anal cells subequal in length, the lower
with two veins, the upper with one, and no cross-vein between
the first branch of the anal vein and the vein from anal cell.
The costal cells are about as long as broad, and the antennae
are as near to the ocelli as to the eyes ; the branches of the
median vein are simple, and there are but three cross-veins
from radial sector to radius.

The type is N. filicornis Banks (sub Chauliodes). This
genus includes also Chauliodes californicus Walker, C.
angusticollis Hagen, C. cinerascens Blanchard, and N. hum-
eralis Banks.

Hermes Gray.

This genus is restricted to a few forms closely allied to the
type species, H. maculipennis Gray. This is the only species
of this genus that I have examined. There are five or six
cross-veins from the radial sector to the radius.

Protohermes van der Weele.

In spite of their pale coloration the species of this genus are
extremely closely related to Hermes. I have examined only
albipennis Walker, anticus Walker, and grandis Thunberg.
These have five or six cross-veins from radius to radial sector,
and at least one branch of median vein is forked.

Corydalis Latreille.

The most important character for the distinction of this
genus is the strongly deflected labrum, and the corresponding
development of the clypeal margin with teeth. Acanthocorydalis
van der Weele may rank as a subgenus, having a spine on
head and more than three cross-veins between radius and
radial sector.

30 ENTOMOLOGICAL SOCIETY

Neuromus Rambur.

This genus, of which N. testaceus Rambur is the type, is
rather variable in appearance ; the larger species show an ap-
proach to Corydalis, while the smaller species look much like
Protohermes. I have examined N. testaceus, N. intimus Mc-
Lachlan, N. latratus McLachlan, and the three American
species, hieroglyphicus Rambur, soror Hagen, and corripiens
Walker ; these latter may be placed in a subgenus — Chloronia —
having but three cross-veins from radius to radial sector, and
branches of median vein forked only near tip.

Nigronia, n. gen.

This genus I erect for the two black-winged species found
in the Eastern States, serricornis Say and fasciatus Walker,
distinguished as indicated in the table. The habits of the
adult flies is quite different from that of the typical Chauliodes.
This genus bears the same relationship to Chauliod'es that
Protohermes does to Hermes.

Chauliodes Latreille.

In this genus I have examined our two species, pectinicornis
Linnaeus, and rastricornis Rambur, C. diversus Walker from
New Zealand and C. japonicus McLachlan from Japan. In
C. diversus the pronotum is longer than broad ; and in this and
C. japonicus the costal cells are as long as broad.

It may be well here to add some points wherein the Sialinae
differ from the Corydalinae. In Sialis there are no ocelli ; the
4th tarsal joint is bilobed ; the basal tarsal joint is about twice
as long as the apical (subequal in the Corydalinsej ; the anal
and cubital veins of fore-wings are both simple (forked in
Corydalinae) ; the upper branch of radial sector sends a few
branches to the costal margin (very rarely one in the Cory-
dalinge). There are three cross-veins from radius to radial
sector as in many Corydalinae.

NOTES ON A FEW APPARENT CASES OF SYNONYMY IN

LEPIDOPTERA.

By HARRISON G. DYAR.

Kodiosoma fulva Stretch.

New synonym, Kodiosoma otera Barnes, Can. Ent., xxxix, p. 10, 1907.

The female type agrees in general with the female of the
variety tricolor, the border of the hind wings being narrower,

OF WASHINGTON. 31

the band of the fore wings broader and more curved. Con-
sidering the range of color in fulva, I think that otera can not
maintain specific rank, perhaps not even varietal.

Eubaphe ostenta Hy. Edwards.

New synonym, Holomelina calera Barnes, Can Ent, xxxix, p. 10,
1907.

Doctor Barnes's type is a female, and differs from the ordi-
nary female of ostenta in having the black border of the hind
wings broken down a little on the inner side and the costal
red shade of fore wings extended to the outer margin. These
are accidental variations, not indicating even a variety. I
have perfectly normal specimens from the same locality as the
type of calera.

Erastria nigellus Strecker.

New synonym, Erastria immuna Smith, Ann. N. Y. Acad. Sci.,
xviu, p. 124, 1908.

Mr. Merrick has kindly given me a specimen of Erastria
immuna Smith, which was described from his collections. It
agrees well with a careful pencil drawing of Strecker's type
of Epizeuxis nigellus, which is before me, and I think it prob-
able that Professor Smith has redescribed the Strecker species
in another, more correct genus. I therefore follow his ge-
neric placing.

Timora toralis Grote.

I recently published some notes on Botis toralis Grote, show-
ing that it was a noctuid, and referring it to the subfamily
Acronyctinse. A re-examination shows that the species has
distinct spines on the legs and should be referred to the
Agrotinse. A specimen was sent to Sir George Hampson at
the British Museum, who places it in the genus Timora Walker
(Rhodosea Grote), where it will form the second North
American species.

Homohadena terminellus Grote.

New synonym, Homohadena Candida Smith.

The receipt recently of some specimens from Mr. F. C.
Pratt in Texas labelled Adipsophanes terminellus Grote made
obvious the above synonymy. Terminellus was previously un-
known to me, but I recognized in Mr. Pratt's specimens Homo-
hadena Candida Smith, a type of which is before me. On
reading Grote's description, I have no doubt but that Mr.

32 ENTOMOLOGICAL SOCIETY

Pratt's identification3 is correct. The longitudinal black stripe
is absent in terminellus, but present in my type of Candida.
It is evidently of no specific value, however. I adopt Pro-
fessor Smith's generic reference as the more recent and there-
fore probably the better. The species has apparently a still
earlier name in Axylia vitrina Walker, specimens of which
from Jamaica, before me, agree rather closely with our Texan
species, but I have some hesitation in referring our species
definitely to the insular form.

Perigea roxana Druce.

Mamestra roxana Druce, Biol. Cent.-Am., Lep. Het, n, p. 476, 1898.
New synonym, Perigea lucetta Smith.

The species occurs at various points in Mexico and extends
its range into Colorado, whence it was described by Professor
Smith, two years later than Druce's description. I have six
specimens before me of roxana from Orizaba and Jalapa,
Mexico, and the male type of lucetta from Colorado.

Papaipema pterisii Bird.

Papaipema pterisii Bird, Can. Ent, xxxix, p. 310, 1907.

New synonym, Gortyna triorthia Dyar, Can. Ent., XL, p. 79, 1908.

In determining my species to be new, I had overlooked Mr.
Bird's description of pterisii, although I supposed I had read
the descriptions of all his species. Later Mr. Bird sent me a
cotype, among others, to be deposited in the National Museum,
and I at once recognized my species, but not in time to pre-
vent the synonym.

Hadena patina Harvey.

New synonym, Dipterygia minorata Barnes, Can. Ent., xxxix, p. 13,
1907.

Doctor Barnes's type is before me, and is the dark form of
patina in which the fore wings are almost wholly black. The
species is recorded from the District of Columbia, Texas, and
Mexico; I have specimens from Florida, and Dr. Barnes's
record adds Arizona, as would be expected.

Lophoceramica artega Barnes.

Tricholita artega Barnes, Can. Ent., xxxix, p. 64, 1907.

I propose the new generic term Lophoceramica for Tricho-
lita artega Barnes, the genus being allied to Ceramica Guen.,

a In a letter recently received Mr. Pratt refers the identification to Dr.
Wm. Barnes, through Mr. Lacy of Texas.

OF WASHINGTON. 33

and differing chiefly in the hairiness of the eyes. In Ceramica
the eyes are densely hairy throughout, in Lophoceramica only
on the posterior half. The genus should find place in Sir
George Hampson's fifth volume on page 447. The females
have a large white tuft covering the end of the abdomen. L.
artega is closely allied to a Mexican species, L. pyrrha Druce
(Hydroecia pyrrha Druce, Ann. & Mag. Nat. Hist. (6), xm,
p. 359, 1894), but is probably sufficiently distinct therefrom to
preserve its specific identity, at least until a larger series of
artega has been obtained. I have before me the female type
of artega and a male and two females of pyrrha.

Coenipeta bibitrix Hiibner.

New synonym, Eubolina meskei Hy. Edwards.

This common Mexican species occurs also in Texas, on the
testimony of Hy. Edwards's type, which is in the National
Museum. The species is extremely variable, but I have a
specimen from Coatepec, Mexico, that exactly matches
Edwards's type. Specimens in the Schaus collection extend
the range to Brazil and Cuba. References to the species will
be found in the Biologia (i, p. 350).

Petrophora iduata Guenee.

New synonym, Xanthorhoe planata Taylor, Can. Ent., XL, p. 59, 1908.

Mr. Taylor proposes a new name for the American form
of P. fluctiiata L., but fails to indicate why the name iduata
Guen. should not be used. Iduata was described from two
males from Canada and the name and reference are given
plainly in Bui. 52, U. S. National Museum in the synonymy of
fluctuata. Admitting Mr. Taylor's contention that the Ameri-
can and European forms are specifically distinct, I think
Guenee's earlier name should be employed.

Odontoptila siculodaria Schaus.

New synonym, Pigia albiserpentata Pearsall, Sci. Bui., Brookl. Inst.
Mus., i, p. 212, 1906.

Mr. Schaus's type is from Oaxaca, Mexico, but agrees well
with specimens from southern Arizona, Baboquivari Mts.,
Arizona, and Brownsville, Tex.

Campometra cinctipalpis Smith.

New synonym, Campometra mascara Schaus, Ann. Mag. Nat. Hist.,
(7), vin, p. 42, 1901.

Mr. Schaus's type is before me and extends the known range
of our Texan species to Venezuela. I have six specimens from

34 ENTOMOLOGICAL SOCIETY

Brownsville, Tex., very variable, but of a characteristic spe-
cific habitus. The Venezuelan specimen is not extreme.

Percnoptilota fluviata Hiibner.

New synonym, Plemyria mortuaria Schaus.

I have not found the place of description of Mr. Schaus's
species, but his type is before me from Castro, Parana, Brazil.
It is a normal male specimen of this widely distributed insect.
Mr. Warren has labelled a male specimen Orthonana obstipata
Fab., which apparently gives us a still older name for our
species.

Hydriomena latirupta Walker.

New synonym, Plemyria paranensis Schaus, Trans. Am. Ent. Soc.,
xxvn, p. 273, 1901.

Mr. Schaus's type is a male of normal appearance. The
female specimens in the collection are labelled Plemyria fluvi-
ata Hiibn. ; this confusion no doubt accounts for Mr. Schaus
having renamed these forms. This species thus appears to be
likewise very widely spread.

Gelasma masonaria Schaus.

Nemoria masonaria Schaus, Journ. N. Y. Ent. Soc., v, p. 161, 1897.
New synonym, Chlorochlamys volantaria Pearsall, Sci. Bull., Brookl.
Inst. Mus., i, p. 214, 1906.

Described from Mexico; Arizona specimens are not distin-
guishable. The reference to Gelasma Warren I find in the
list of the Schaus collection, and is to be attributed to Mr.
Warren, I believe.

Synchlora cupidenaria Grote.

Racheospila cupidenaria Grote, Can. Ent., xii, p. 218, 1880.
New synonym, Synchlora louisa Hulst.

Grate's species was sunk as a synonym of Racheospila lix-
aria Guenee, and subsequently described as new in another
genus by Doctor Hulst. I have specimens compared with
Grote's type in the British Museum by Mr. Schaus and Hulst's
type of louisa before me.

Racheospila ocellata Stoll.

Phalana Geometer ocellata Stoll, Suppl. Cramer's Pap. Exot., pi.

xxxiv, fig. 9, 1791.

New synonym, Racheospila xystcraria Hulst, Ent. Amer., u, p. 121,
1886.

OF WASHINGTON. 35

This species enters our region in southern Florida, whence
it was redescribed by Doctor Hulst. It is widely spread in
the tropics.

Racheospila centrifugaria Herrich-Schaeffer.

Geometra centrifugaria Herrich-Schaeffer, Corr.-Blatt. zool.-min.

Ver. Reg., xxiv, p. 182, 1870.
New synonyms,

Geometra protractaria Herrich-Schaeffer, Corr.-Blatt. zool.-min.

Eucrostis hollandaria Hulst, Ent, Amer., n, p. 122, 1886.

Eucrostis jaspidcaria Hulst, Ent. Amer., n, p. 122, 1886.

Synchlora viridipurpurea Hulst, Can. ent., xxx, p. 159, 1898.

This species is common to Cuba and southern Florida. The
markings vary remarkably; the white spot above anal angle
may be absent or replaced by a large black blotch.

Racheospila sitellaria Guenee.

Racheospila sitellaria Guenee, Spec. Gen., ix, p. 374, 1857.
New synonyms,

Geometra congruata Walker, Cat. Brit. Mus., xxn, p. 511, 1861.

Synchlora louisa var. hulstiana Dyar, Proc. Ent. Soc. Wash., w,
p. 457, IQOI.

Originally described from Haiti, but occurs through the
West Indies and in southern Florida.

Phorodesma niveociliaria Herrich-Schseffer.

Eucrostis niveociliaria Herrich-Schaeffer, Corr.-Blatt. zool.-min.

Ver. Regensb., xxiv, p. 182, 1870.
New synonym, Eucrostis saltusaria Hulst, Ent., Amer., n, p. 122,

1886.

Another of the green geometers common to Cuba and south-
ern Florida. The reference to Phorodesma Boisd. is due to
Mr. Warren, whose label in the Schaus collection is so written.

A NEW TETRANYCHUS.

[Acarina, Tetranychidse.]

By NATHAN BANKS.

Tetranychus opuntiae, n. sp.

Color wholly bright red. Body rather more elongate than usual ; with
the usual bristles, but all very long, those on shoulders more than one-
half width of body, none of them on tubercles. Palpi long, penulti-
mate joint ending in a stout spur overlapping in part the next joint,
thumb with a very stout finger, truncate at tip and bearing a hair on
each side, one of them very stout, and on upper side of thumb a slender
finger. The mandibular plate long, tapering somewhat lo the rounded
tip, which is not emarginate in the middle. Legs large and long, and
having very long bristles ; femur I about twice as long as tibia I, and
tarsus I nearly as long as femur, the large mid-dorsal bristle of tarsus I
as long as the joint; claws four-cleft.

This species occurs on prickly pear cactus (Opuntia} in
Texas ; it was collected by Mr. D. Griffiths of the Department
of Agriculture, mostly near San Antonio, in March. It is very
injurious to the cacti.

The following paper, in the absence of Mr. Knab, was read
by the secretary:

THE EARLY STAGES OF SAYOMYIA PUNCTIPENNIS SAY.

[Diptera, Culicidse.]
By FREDERICK KNAB.

Sayomyia punctipennis appears to be the most common
species of its genus in the upper Mississippi Valley and al-

OF WASHINGTON. 37

though the larva has been frequently alluded to it has, up to
the present, remained uncharacterized. A few larvae of this
form were taken by the writer at Urbana, 111., on October 2,
1904, in a temporary puddle, where they were associated with
numerous larvae of Culex pipiens and a few of Culiseta conso-
brimis. In confinement the larvae of Sayomyia preyed upon
the young larvae of Culex, and from one that pupated the
imago was disclosed October 10.

The larva of this small species resembles very much the
larvae of the other species of Sayomyia in general appearance.
When the larva apprehends danger it sinks slowly to the
bottom, maintaining throughout its horizontal position. The
writer has also observed this maneuver in the larvae of other
species of the genus and in those of Caret lira (Mochlonyx).
Dr. Fr. Meinert, in his work " De eucephale Myggelarver,"
has already noted this action of the larva, without, however,
offering any explanation of the manner in which it is ac-
complished. When suddenly disturbed the larva changes its
position very rapidly by a switching motion in which the two
extremities are brought nearly together.

A few more larvae of the present species were obtained on
Nov. 8 when dipping for Culex larvae in Salt Fork, a small
stream on the outskirts of Urbana. In February, 1905, more
larvae were obtained by some university students from a pond
known as Crystal Lake, formed by the damming of the above
mentioned stream. When a hole was cut through the ice
these larvae rose to the surface.

This species is the " Corethra larva " alluded to by Dr. S.
A. Forbes in several of his writings, as the writer ascertained
by an examination of the material in the collection of the
Illinois State Laboratory of Natural History. From the data
accompanying this material it appears that the larva of this
species frequents the open water of lakes and rivers. Two
plankton hauls from the Illinois River in mid-stream at Ha-
vana, 111., August 12 and October 14, 1896, contain specimens
of this larva. Other specimens, from Cedar Lake, 111., taken
October 23, 1882, are those referred to by Doctor Forbes in
his articles, " Leptodora in America " (Amer. Naturalist, 1886,
p. 1057) and "The Lake as a Microcosm" (Bui. Peoria Sci.
Assn., reprint, 1887, p. 8).

Although closely similar to other species, the larva of
Sayomyia punctipennis possesses distinctive characters in the
form of the leaf-like appendages of the ventral surface of
the head and in other structural details. Behind the eighth
abdominal segment a pointed hood-like flap projects back-

ward. This may perhaps be present in the larvae of other
species, as it would be easily overlooked in such transparent
larvae. A more detailed description follows :

the thorax and gradually tapering to the slender terminal segment. Air

vesicles present in the thorax and seventh abdominal segment. Body
entirely colorless and transparent. Antennal bristles and mouth parts
pale yellow-brown; foramen of head tinged with brown; eyes black;
air vesicles with round, closely approximated, dark-brown pigment
spots.

Head (fig. 6) rather small, broadest at the eyes. Eyes situated
behind the middle, large, compound, with an emargination behind to
receive the small accessory eye. The head is prolonged anteriorly into
a process which bears at its extremity the closely approximated anten-

nae. This process about equals in length the head itself; at its base
it is about a third as broad as the greatest width of the head ; near
the middle it is much narrowed by the concave sides. Antennas in-
serted close together at the extremity of the process, directed down-
ward. They are of a single stout elongate segment bearing at its
tip six tapering slightly curved spines. Of these spines four are of
nearly equal length with the antennal segment and one is a third

shorter than these, while the sixth spine is small and very short.
Inserted ventrally, just behind the antennae, is a pair of pendant append-
ages about equal in length to the antennal segment. Each of these
appendages consists of five long filaments united at the base. About
midway between these and the maxillae are delicate pendant organs
termed " leaflike appendages" by Dr. E. P. Felt (N. Y. State Mus.,
Bui. 79). In the present species these leaflike appendages are ex-
tremely long and slender and their length is about two thirds that of the
antennal segment. Beyond the base these appendages expand into a
small lamellate portion which remains quite small and again tapers
into the very long and slender point. The anterior margin of the
appendage gives rise to a series of long rays and on the posterior
margin the basal fourth is unarmed while beyond are a succession of
these slender spines. The maxillae are long, stout and prominent,
projecting downward just in front of the mandibles. Outwardly, near
the front margin at about the middle, there is a slender spine. Near
the apex of the maxillae there is a group of coarse setae. The mandi-
bles are large, stout and prominent, concave on the inner side and
with six long, stout, curved teeth on the apical margin; on the outer
surface there is a coarse spine inserted above the teeth. At the base,
on the inner surface, is inserted a dense tuft of long hairs. The labial
palpi are represented by tubercles bearing a stout, long spine.

FIG. 7. — Sayomyia punctipennis : Terminal segment of larva.

The thorax is elongate, hexagonal; the three segments fused. The
air-vesicles, at its posterior third, are short and rounded, obtusely
pointed in front. First abdominal segment shorter than the succeeding
ones. Air-vesicles of the seventh abdominal segment small, rounded.
Thorax and abdomen with several series of delicate, white, sensory

hairs, mostly stellate. Basally a portion of the ninth abdominal seg-
ment is strongly constricted off into what appears to be a short, dis-
tinct segment; projecting over this, from the hind margin of the eighth
segment, like a hood, is a triangular fleshy flap with its tip prolonged
into a knob. Anal segment (fig. 7) elongate and slender; on each
side, close to the posterior margin, a very regular row of strongly
curved spines, about twelve in each row ; below these are the ventral
hooks which are short and each with two nearly equal teeth. Ventral
rudder of 18 or 19 long, coarse, unbranched ciliate hairs. The four
anal gill-flaps are rather small, elongate. Dorsally the anal segment
bears at its tip two long, straight, plumose setae, and curving over
these another pair of plumose hairs.

Pupa. — Length about 7
mm. Thoracic portions
short and globose, the ab-
domen long. Eyes large,
emarginate for the super-
iorly inserted antennse. The
trumpets large, broadest at
the middle and tapered to
the base and apex ; surface
coarsely reticulate ; apical
opening very minute. The
abdominal segments with
long, stellate, colorless, sen-
sory hairs at the sides near

the posterior margin. Paddles (fig. 8) broader than long, inserted
well apart and directed obliquely outward; the approximating margins
with minute serrations.

The pupa floats below the surface of the water and main-
tains itself in a perpendicular position, the abdomen extended
straight downward. When disturbed it darts about by strokes
of its abdomen with amazing rapidity. The pupa, like the
larva, is colorless. The air bladders of the anterior pair are
distinctly visible in the pupa, in the lower part of the thorax,
but they are not pigmented. When the larva approaches the
pupal period the pigment spots of the air-vesicles break into
irregular groups, leaving spaces between them, and the pig-
ment is probably removed in the process of pupation.

abdomen of pupa.

In discussing this paper, Doctor Dyar said that the food
habits of the Sayomyia in the open lakes were not known,
but that the larvae were very destructive to other mosquito
larvae in puddles near Washington.

NOTES ON THE SPECIES OF ACROBASIS, WITH DE-
SCRIPTIONS OF NEW ONES.

[Lepidoptera, Pyralidae, Phycitinse.]
By HARRISON G. DYAR.

Mr. Charles R. Ely, of Washington, D. C, recently left
with me a box of pyralids collected by himself, among which
were some Phycitinae. These contained such a fine series of
Acrobasis (over half of the specimens being of this genus)
that I was induced to review the species listed in the genus.
The species of Acrobasis Zeller have a raised ridge of scales
near the base of the fore wings; the males have a small
projection on the basal joint of the antennas and, in some
species, various tracts of modified black scales on the under-
side of the wings. Doctor Hulst, in reviewing the genus
(Trans. Am. Ent. Soc., xvn, p. 123, 1890), casts doubt on the
specific value of these black markings, but for myself, I be-
lieve in them entirely, as they are not variable in the several
species. They are secondary sexual characters, of as much
importance as the projection on the antennse, which Doctor
Hulst uses for generic definition. While I think that these
characters ought not to be used as generic, there is certainly
no doubt of their specific value. I would base the separation
of the species primarily upon them, as in the following table.
In several instances species are indistinguishable as imagines,
but have dissimilar larval habits and food plants. These are
bracketed in the table. No attempt should be made to identify
species without male specimens, much less to found new spe-
cies on such material. Two species, cirroferella Hulst and
fructetella Hulst, are unknown to me and not identifiable from
the descriptions.

also Doctor Hulst's identification label, Acrobasis angusella
Grote. Mr. Grote's separation of this and the following
species (Papilio, i, p. 14, 1881) is pertinent and can not be
improved upon.

Acrobasis demotella Grote.

Four specimens are before me : A male, New Brighton, Pa.,
June 5, 1902 (H. D. Merrick) ; three females, Tryon, N. C.,
May 28, 1903 (W. F. Fiske) ; 2 miles west of St. Louis, Mo.,
June, 1904 (Aug. Busck) ; the third presumably from Chicago,

remains unknown.

Acrobasis nigrosignella Hulst.

I have a single specimen that I refer to this species, Tryon,
N. C, May 7, 1904 (W. F. Fiske). Ragonot refers the name
as a synonym to his minimella (Mon. Phyc. Gall., i, p. 105,
1893), but I can not concur in this view. Minimella Ragonot
should rightly have no standing, being described from a
female only, and from its size, markings, and locality I refer
it to nebulella Riley (see below).

Acrobasis eliella, n. sp.

Head and thorax gray, with a reddish shade; abdomen gray, the seg-
ments ringed with whitish. Fore wing gray, shaded with red at the
base, the scale-ridge black, extending half way across the wing, resting
on inner margin ; beyond it a broad orange-red band, narrowing toward
costa and followed by a black shade on the costal half; discal dots
joined; outer line mesially exserted, slender, denticulate, with an
oblique inward shade from its upper angle, followed by a red shade.
Hind wing gray. In the male there is a broad black streak on the
hind wings below from base to beyond middle, approaching the costa at
its end. Expanse, 19 mm.

Four males and six females East River, Conn, August 20,
1906 (Chas. R. Ely).

Type. — No. 11547, U. S. National Museum; three speci-
mens in Mr. Ely's collection. Named in honor of Mr. Charles
R. Ely.

Acrobasis stigmella, n. sp.

Head yellowish white on face and vertex, the palpi tipped with white;
collar white in the middle, the rest of the thorax dark purplish gray;
abdomen yellowish gray, ringed with dark at the bases of the segments,
the basal segments brown dorsally. Wings purplish gray, the basal
space very dark, the scale ridge scarcely darker, followed by a narrow
obscure reddish shade; discal dots small, separated; outer line whitish,
not strongly relieved, excurved in the middle, dentate, surrounded by a
darker purplish shading. Hind wings pale gray with a yellowish tint.
In the male there is a black subcostal streak on the fore wings below
and an elongate oval patch close to the costa of hind wing below before
the middle. Expanse, 19 mm.

Two males, one female, bred from larvae on hickory, Fort
Lee, N. J., May, 1896 (H. G. Dyar) ; one female, East River,
Conn., August 20, 1906 (Chas. R. Ely).

Type. — No. 11548, U. S. National Museum.

44 ENTOMOLOGICAL SOCIETY

The larvae web up the three leaflets at the end of a leaf and
form a mine in the stem where they are attached, or web up
a little leaf and burrow in the young wood. They occur only
in the young, unfolding leaves. The larva is cinereous green,
the head, cervical shield, and thoracic feet shining black ; anal
plate brown. The body tapers abruptly at both ends. Tu-
bercles small, brown, the hairs long, black; thoracic segments
with three annulets, abdominal ones with two, the tubercles
normal, iv and v closely approximate, i and ii nearly in line.

Acrobasis caryivorella Ragonot.

I refer to this species a male and a female from the Texas
Agricultural and Mechanical College Insectary, July 12 and
20, 1903 (A. C. 225) ; a female, Burnet Co., Tex. (F. G.
Schaupp through W. D. Kearfott), and two males, East River,
Conn., August 8, 1906, and September 2, 1907 (Chas. R. Ely).

Acrobasis hebescella Hulst.

Six specimens from Brownwood, Tex., bred at the Insectary
of the U. S. Department of Agriculture from larvae on pecan
mining into the young buds ; one specimen, East River, Conn.,
August 2, 1906 (Chas. R. Ely). The species is very close to
caryivorella Rag., but differs in the obsolescence of the outer
line, all the space beyond the scale ridge being nearly uniformly
cinereous.

Acrobasis evanescentella, n. sp.

Entirely similar to A. caryivorella Ragonot, somewhat darker in
color. The specific difference lies in the sex-mark of the male,
which is pale gray, overlaid by gray scales, not deep black and dis-
tinct as in caryivorella; the mark is also narower.

Twelve specimens, Orlando, Fla., bred from larvae on pecan
by a correspondent of the U. S. Department of Agriculture;
breeding No., Chittenden, 250.

Type. — No. 11981, U. S. National Museum. Seven of the
types deposited in the National Museum, the rest with Doctor
Chittenden.

Acrobasis kearfottella Dyar.

Besides the types, I have seen a specimen from New
Brighton, Pa., now in the collection of Mr. F. A. Merrick, to
whom I returned it. The species is larger and stouter than
the following, though in general similar.

Acrobasis palliolella Ragonot.

Ragonot and Hulst place albocapitella Hulst in the synonymy
of this species, correctly, I presume, though I have seen neither

OF WASHINGTON. 45

of the types. I have ten specimens in the collection under this
label, Palatka, Fla., on pecan, issued May 27, 1903; Olustee,
Fla., June, 1904; Black Jack Springs, Tex. (through Dr. Wm.
Barnes) ; Cairo, Ga., issued June 6, 1903 ; Blacksburg, Ga., on
pecan, issued May 28, 1902 (W. R. William) ; Washington,
D. C, on walnut, issued June 7, 1903 (Aug. Busck) ; Chicago,
111., July, 1900 (Coll. W. D. Kearfott). The specimens pos-
sess the white thorax and base of fore wings, but the white
is more or less grayish and grades into the color of the fol-
lowing species. I expect it will be found that palliolclla is
not more than a variety of nebulella Riley. They differ in no
other respect.

Acrobasis nebulella Riley. (i

This name is listed as a variety of Mineola indigenella
Zeller, but Riley's type before me is clearly an Acrobasis and
differs from palliolella only in the gray color of thorax and
,base of fore wings. Minimella Rag., made to replace Hulst's
nigrosignella by Ragonot and referred to the synonymy of
caryce Grote by Hulst, will find place here as a synonym. It
was described from females and so can not be positively re-
ferred, but it contradicts this species in nothing, and its small
size favors the reference as this is the smallest species before
me. Ragonot's figure agrees well with specimens of nebulella,
and the locality is consonant. I have 23 specimens before me,
4 bred by Doctor Riley on hickory and walnut, including the
type of nebulella; Atlanta, Ga. (W. M. Scott) ; Texas (Jacob
Boll), this specimen submitted to Ragonot by Riley in 1886
and marked " Acrobasis, too poor to name " ; also submitted
to Dr. Hulst in 1900 and labelled " probably Mineola nebu-
lella;" Kerrville, Tex., at light, May 30 to June I, 1906 (F.
C. Pratt) ; Blackshear, Ga., on pecan, issued June 12, 1902
(Dept. Agr., No. 8637) ; Rhinebeck, N. Y., July 27, 1888 (H.
G. Dyar), the latter a female and the reference therefore less
certain.

Acrobasis latifasciella, n. sp.

Agrees entirely with the description of A. eliella above; the same
words might be repeated. It differs, however, in lacking all traces
of sexual markings on the wings beneath in the male.

One male, New Brighton, Pa., Aug. 4, 1903 (H. D. Mer-
rick) ; three males and one female, Plummers Island, Mary-
land, July 9, August 3, and 10 (Busck, Schwarz, and Barber) ;
one female, June 22, 1886, bearing the number 2504 (pre-
sumably Doctor Riley's) and determined by Hulst as Aero-

basis carycc. Mr. Ely has two specimens taken near Wash-
ington, D. C., by himself.

Type. — No. 11549, U. S. National Museum.

The Riley notes, preserved at the Department of Agri-
culture, contain under the number 2504 two entries, Kirkwood,
Mo. (Miss Murtfeldt) and Virginia (Pergande), the larvae
on hickory in both instances.

Acrobasis normella, n. sp.

The pattern and colors are the same as in the allied species, but the
orange-red space beyond the scale ridge is narow and there is an
oblique white shade from beyond the end of the scale ridge to the
costa at inception of the outer line, relieving the small, separate discal
dots strongly. The male has no sexual markings beneath. Expanse,
19 mm.

One male and one female, East River, Conn., August 2,
1907 (Chas. R. Ely).
Type. — No. 11550, U. S. National Museum.

Acrobasis rubrifasciella Packard.

I have several specimens under this label, but am not cer-
tain of any of them, as none is bred. The food plant is alder.
Specimens not bred can not be distinguished from the follow-
ing species:

Acrobasis comptoniella Hulst.

I have a series of specimens bred from sweet fern at Center
Harbor, N. H. (H. G. Dyar). The larvae have the head dark
red, black in the sutures ; cervical shield pale reddish, con-
trasting; body blackish, with broad diffuse dorsal and lateral
pale reddish bands ; feet black. The tubercles are minute and
inconspicuous. Mr. Ely has a large series captured at East
River, Conn. He says that the sweet fern is abundant at that
locality.

Acrobasis caryae Grote.

Ten specimens are before me, bred from pecan at the In-
sectary of the Department of Agriculture under the number
5023, from Summerton, S. C., and three others somewhat
doubtfully referred, as the food plants are not known. With-
out the food plant, this species is indistinguishable from the
following. The larval habits of the two seem different enough,
for while caryc? eats into the young buds of hickory, bctulella
feeds on the leaves of birch later in the season, forming a
hard ball of excrement surrounded by a loose web.

OF WASHINGTON. 47

Acrobasis betulella Hulst.

On black birch, Maine, July 18-23, 1887 (A. S. Packard) ;
two, Center Harbor, N. H., larvae on birch, June 24, 1902,
adult July 9, 1902 (H. G. Dyar) ; larva in web on birch,
Platte Canyon, Colorado, June, 1901, adult, July I, 1901 (H.
G. Dyar) ; five, bred from Birch, Sisson, Cal. (A. Koebele) ;
one, bred from white birch, Hampton, N. H., July 9, 1906
(S. A. Shaw). The Calif ornian specimens are a shade paler
and smoother than the Eastern specimens, but do not greatly
differ ; the Coloradan specimen is as dark as the Eastern ones.

Acrobasis coryliella, n. sp.

A single male specimen before me, scarcely distinguishable
from carycs and betulella, but labelled " Phycita on Hazel,
June 14, 15, 1876. No. 96 " in a handwriting which may pos-
sibly be that of Doctor Lintner. It bears also Grote's de-
termination "Acrobasis rubrifasciella." The food plant indi-
cates a different species and the moth also is grayer, more
uniform, without white shading, the outer line more distinct
and finely crenulate. Mr. Ely has kindly given me three
specimens from East River, Conn., that seem the same but
have no record of food plant. Their dates are August 6
and ii.

Type. — No. 11551, U. S. National Museum.

Acrobasis malipennella, n. sp.

Head and thorax cinereous, tinged with coppery red; abdomen dark
gray, the segments whitish at their tips. Fore wing short and broad,
the cell broad, veins 2 and 3 arising close together, 4 and 5 from a point
distant from them; gray, the scale ridge black, reaching half way across
the wing, followed by a red shade and a black triangular cloud on
costa; median field whitish frosted toward costa, enclosing a single
black discal dot near the costal edge; outer line obsolete. Hind wing
with the lower angle of the cell produced, veins 4 and 5 stalked ; uni-
formly dark gray. Expanse, 13 mm.

One male, East River, Conn., August, 1907 (Chas. R. Ely).
A second specimen is possibly the female of this species, but
its wings are long and narrow as usual, while the venation is
normal ; the color resembles that of the male specimen, but
the outer line is visible, mesially exserted, crenulate, outwardly
pale, followed by a dark red shade ; discal dots double, sepa-
rate, black.

Type. — No. 11552, U. S. National Museum.

The male is easily distinguished by its peculiar short wings ;
the female, if rightly associated, has the wings of normal

shape and resembles A. normella Dyar. It is redder than that
species and without the conspicuous white mesial shading.

Acrobasis sp.

Two females before me differ from anything in the collec-
tion, but may await the discovery of the male before being
named. They are very dark gray, the scale ridge slender and
slight, the following light shade very narrow, orange-red.

NOTES ON SOME AMERICAN COCHLIDIIOffi, WITH
DESCRIPTIONS OF NEW SPECIES.

[Lepidoptera.]
By HARRISON G. DYAR.

Sibine apicalis Dyar.

The series of this species has been increased by 2 males,
Cordoba, Mexico, May, 1906 (Wm. Schaus) ; 4 males,
Cordoba, Mexico, August, 1906 (R. Miiller) ; 2 males and 2
females, San Jose, Costa Rica, October, 1906 (Wm. Schaus) ;
I female, La Florida, Costa Rica, March, 1907, and I male,
Guapiles, Costa Rica, May, 1907 (Wm. Schaus).

This species seems, in series, distinct from the North Amer-
ican Sibine stimulea Clemens, being larger, and more spotted,
the spots irregular and yellow instead of white.

Sibine sp.

Several specimens of Sibine have been sent in by Mr. Schaus
which I can not place satisfactorily. The species of Sibine
must be worked up from the larval side before their specific
limits can be determined.

Parasa imitata Druce.

One male, Orizaba, Mexico (R. Miiller).

Parasa fauna, n. sp.

Vertex of head and thorax green, face brown, as also lateral mar-
gins of patagia and a central line on thorax. Abdomen brown. Fore
wing green, a brown patch at base resting on costa, the outer margin
narrowly brown with an enlargement below vein 2 and a larger one
between veins 4 and 6; a deeper green patch at end of cell. Hind
wings and under side brown. Expanse, 37 mm.

Parasa wellesca Dyar.

Mr. Schaus has sent in specimens from the following new
localities: 3 males, San Jose, Costa Rica, October, 1906; I
male, Sixola River, Costa Rica, July, 1907 ; i male, R7.

All the specimens are somewhat larger than the types. No
female has yet come to hand. The following table will sepa-
rate the American species of Parasa in which the fore wings
have a green band in both sexes :

Mr. Schaus has collected i male, La Florida, Costa Rica,
July; i male, Zent, Costa Rica, February, 1907; 3 males,
Banana River, Costa Rica, March, 1907.

Metraga emilia, n. sp.

Fore wings reddish brown, the outer and inner margins broadly dark
purple; a faint discal dot and outer line, limiting the marginal dark
shade; hind wings dark straw-color, the fringe purplish, especially so at
anal angle. Head and thorax ferruginous, abdomen ochraceous. Ex-
panse, 18 mm.

One male, Tabernilla, Canal Zone, Panama (Aug. Busck).

Type. — No. 11514, U. S. National Museum.

Allied to M. rubicolor Dyar, but the outer margin is shaded
as well as the inner and the hind wings are pale. Named in
honor of Miss Emily Baker, of Hyattsville, Md.

Natada salta Druce.

Specimens have lately been received from Cordoba, Mexico,
three, May, 1906, and one, April, 1906 (Wm. Schaus) ; four,
Sixola River, Costa Rica, April, 1907; one, Chiriquicito,
Panama, April, 1907 (Wm. Schaus) ; one, Merida, Venezuela
(S. E. Briceno).

Natada arpi, n. sp.

A rather large species, nearly allied to N. bergii Dyar. The color of
the fore wing is paler than in bergii, shining grayish, the brown shading
confined to a patch at origin of vein 2 and a large cloud about lower
half of outer line; discal dot rounded, blackish; outer line brown,
fainter and curved outward where it traverses the brown cloud. Hind
wings dark gray-brown. Thorax and base of abdomen tinged with red.
Expanse, 37 mm.

One male, Rio de Janeiro, Brazil (J. Arp).
Type. — No. 11539, U. S. National Museum.

Talima straminea Schaus.

Two males, Sixola River, Costa Rica, April, 1907 (W.
Schaus).

Epiperola vafera Druce.

I referred this species to Paleophobetron on a specimen
from Maroni River, French Guiana, in the Schaus collection.
The palpi in this specimen are apparently distorted, as addi-
tional examples from Palma Sola, Venezuela, show well-
developed palpi, reaching to the middle of the front, thus
placing the species in Epiperola.

OF WASHINGTON. 51

Epiperola vaferella, n. sp.

Shining blackish brown, the fore wings of this color to the outer
line, which is narrow, pale, single, slightly curved, reaching from outer
sixth of costa to middle of inner margin ; space beyond this line more
grayish; a pale line at the base of the fringe. Hind wings of the color
of the outer space of fore wings, with a pale line at the base of
fringe. Expanse, 21 mm.

One male, La Florida, Costa Rica, July, 1907 (W. Schaus).

Type. — No. 11540, U. S. National Museum.

Allied to P. vafera Druce, but the outer space is paler, the
line single, not doubled, more curved and arising farther from
the apex.

Epiperola monochroma, n. sp.

Entirely bright brownish ochraceous without any markings. The
wings are rather long and pointed, the head prominent, with large eyes,
of the general build of Perola sericea Moschler, though smaller. Ex-
panse, 30 mm.

Four males, Bocas del Toro, Panama, April, 1907, and Chiri-
quicito, Panama, April, all collected by Mr. Schaus.
Type. — No. 11541, U. S. National Museum.

Tanadema neutra, n. sp.

Allied to Tanadema mas Dyar, but the lines on fore wing broad,
distinct, dark gray, the two lines alike, the discal mark forming part
of the inner line. The lines are rather sharply angled on the veins,
the inner one sharply produced at the lower end of the cell. The
ground color of the wings is not so red as in T. mas, being of a paler
color in two specimens, dark in the other but still without the red
cast. Expanse, 19 mm.

Three males, Sixola River, Costa Rica, April, 1907; Tuis,
Costa Rica, July, 1907; Banana River, Costa Rica, March,
1907 (Wm. Schaus).

Type. — No. 11542, U. S. National Museum.

Packardia ceanothi, n. sp.

Allied to P. elegans Packard, but bright brownish ochraceous instead
of bronzy brown. In the dark form (corresponding to elegans) the
fore wings are brownish ochraceous, crossed by two oblique and one
reversed curved pale line, the inner line broadly shaded without with
dark fuscous brown, the curved line ending at the anal angle in two
superposed dots. Hind wings thickly blackish irrorate. In the pale
form (corresponding to variety fusca Pack.) the markings are nearly
obliterated, being of almost the same shade as the ground color. Hind
wings pale straw-color.

52 ENTOMOLOGICAL SOCIETY

Seven specimens, bred from larvae on Ceanothus at Tryon,
N. C. The larvae are similar to those of P. elegans, and were
so determined in the field. However, Mr. Fiske, who was
with me, thought they might be a new species as they seemed
so partial to the Ceanothus, which is not the case with elegans.
His supposition proves to be correct.

By HARRISON G. DYAR.

Mr. F. A. Merrick, of New Brighton, Pa., has handed me
a number of moths, collected in the vicinity of San Diego, Cal.,
for identification. The collections were made by Messrs. Geo.
H. Field and W. S. Wright. The new species among them
are here described wherever there were more than one speci-
men. A number of uniques have been returned to Mr. Merrick
and it is hoped to report on these later when Messrs. Field and
Wright shall have been fortunate enough to secure additional
specimens.

Family ARCTIIDyE.
Subfamily LITHOSIIN/E.

Phobolosia reincarnata, n. gen. and sp.

Palpi upturned to the vertex, fringed with long hair in front which
projects as much as the length of the head; antennae serrate in the male,
simple in the female; tongue moderately long; eyes large, naked; a tuft
of scales projects forward at the top of the vertex; tibiae unarmed, the
hind pair with four long spurs ; fore wing trigonate, pointed, sub-
falcate at the apex, the venation as in JEolosia Hampson (Cat. Lep.
Phal., n, p. 405, 1900) ; hind wing rounded trigonate, rather broad.

Fore wing with the ground pale cinereous whitish, but nearly com-
pletely overlaid with dark shades ; basal space filled in with blackish
gray; inner line gray-brown, forming three outward undulations between
the costa and median vein, a single large one between median and
vein i and another smaller one between vein i and inner margin ; a
whitish space of the ground color on each side of this line, the in-
ception of these white spaces on costa forming a pair of oblique
dashes; median space rilled in with blackish gray, usually heaviest in
the middle; discal mark a black bar or crescent followed by a white

spot that touches the outer line; outer line strongly excurved at the
end of the cell, undulate, gray-brown, edged with white on each side,
the white forming a pair of oblique dashes on the costa, followed by a
row of four similar dashes without any continuing lines, the last one
being nearly at the subterminal line; subterminal space brownish gray
filled; subterminal line whitish, undulate, most strongly produced op-
posite the cell ; terminal space pale gray, not strongly contrasting with
the subterminal line; a terminal brown line which expands between the
veins and forms above vein I and at the apex of the wing a small
brown-black speck; fringe brownish, interlined with white at the base.
Hind wing white, lightly gray powdered, showing a small, faint, darker
discal dot; at the outer margin at the termination of the submedian fold
a triangular brown-black speck accompanied by a white dash ; a ter-
minal brown line; fringe pale. Body parts whitish gray, irrorate with
brown. Expanse, 20-24 mm.

Seven specimens, San Diego, Cal. (G. H. Field), Grapevine,
June 29; Grapta Camp, June 29, 1907; Morena, July 4; South
Arizona, August 1-15 (O. C. Poling) ; Kerrville, Tex., June,
1906, and October, 1904 (H. Lacy).

Type. — No. 11696, U. S. National Museum.

I have described this genus in the Lithosiinae as it falls there
by Sir Geo. Hampson's tables, but it may possibly be found
to be better placed in the Noctuidse, subfamily Erastriinas, some
species of which have vein 8 of the hind wings anastomosing
with the subcostal to nearly the middle of the cell. I am
unable, however, to detect ocelli in the present form, whereas
they are present in the Erastriinae.

Family LIPARID^.
Animomyia morta, n. gen. and sp.

Form slender, wings thin and rounded;
antennae of the male bipectinate, with
very long branches running to the tip ;
eyes large, front rounded, not prominent;
palpi slender, porrect, well exceeding the
front, smoothly ^scaled ; tongue obsolete ;
hind tibiae with two pairs of rather long
spurs, the legs moderate; venation as in
the accompanying figure (fig. 9) ; vein
12 anastomosing with ir, u and 10, and
10 with the stalk of 7-9; vein 5 aris-
ing slightly below the middle of the
disco-cellulars ; hind wing with vein 5
obsolete, only one internal vein.

FIG. g. — Animomyia morta:
Venation of front and hind
wings.

54 ENTOMOLOGICAL SOCIETY

Wings thin and translucent, brownish gray, the fore wing marked
with two faint, darker transverse lines, curved, the outer one somewhat
irregular in the upper half of its course. The large plumose antennae
are very prominent. Expanse, 18-19 mm.

Four specimens, San Diego, Cal. (G. H. Field), Grapevine,
June 29, all males.

Type. — No. 11695, U. S. National Museum.

I am quite in doubt about the proper family reference of this
genus. It falls in the Lymantriidse (Liparidse) by Sir George
Hampson's table if vein 5 of the fore wing be taken as nearer
vein 4 than vein 6, which is the case, but only slightly. How-
ever, there is no bar between the costal and subcostal veins
of hinds wing as called for by the table. The alternative posi-
tion would be in the Geometridse, where it would fall in the
Ennominae. I can not place it exactly by Hulst's table in
default of female specimens, but we have nothing that I know
of in the least like it. It looks like the Lithosian genus
Nudaria.

Family NOCTUID^E.

Subfamily AGROTIN.E.
Euxoa fieldii, n. sp.

Head light ocherous gray; collar clay-color in front, with a central
curved black line, dark gray behind; thorax dark gray with some
ocherous scales centrally; abdomen pale gray. Fore wing with the
costa broadly pale, clay-colored in the male except for a red subapical
stain, infuscated on the outer half in one female, largely infuscated in
the other; basal space below the costa dark gray, separated by black
from the costal area, the black forming a triangular spot at base of
median vein and also on the costa in the females ; inner line forming
three curves, blackish, geminate, pale-filled; claviform black-outlined,
dark-filled, continued by a black line along submedian fold, which in
two of the specimens is bordered on each side by ocherous clay-color;
orbicular small in the male, larger and oblique in the females, clay-
color with a narrow black edge, the center dark-filled in the females;
reniform large, concave on its outer side, clay-color with a narrow
black edge and a concentric darker center ; cell and below to vein 2
black-filled, the median space below dark gray, a red tint in the male ;
outer line obsolete, limiting the pale subterminal space, which is broad
and forms rays centered by the dark veins, cut by a row of black
wedges resting on the pale waved subterminal line ; terminal space
blackish-filled; a terminal row of minute black cusps. Hind wing
whitish in the male with a narrow fuscous border; all fuscous in the
females, the fringe whitish. Expanse, 36-38 mm.

October 18, November 12 and 14.

Type. — No. 11697, U. S. National Museum.

Nearly allied to Euxoa lacunosa Grote, of which it may be a
local form. It is, however, much brighter and more contrast-
ingly marked and the costa is distinctly pale as in wilsonii
Grote ; from wilsonii the color of the hind wings of the male
at once separates it.

Family GEOMETRID^E.

Subfamily ENNOMIN^E.

Glaucina epiphysaria, n. sp.

Light gray, faintly washed with whitish over the middle of fore-
wing; lines broken, obsolete; various fragments of the inner line may
be seen near costa and inner margin and of the outer line at costa
and at end of cell, the small angle at the base of veins 2 and 3 being
most persistent; no discal dot; subterminal line a series of pale arcs
between the veins edging faint dark elliptical spots ; a black line at the
base of the fringe. Hind wing whitish over the disk, gray on the
margin in the female, the inner margin broadly powdery gray, showing
the inception of a transverse dark line, of which various fragments
may be distinguished across the wing; fringe pale with a black basal
line. Expanse, 21 to 28 mm.

One male, two females, San Diego, Cal. (G. H. Field), Oc-
tober 24 and 29.

Type. — No. 11698, U. S. National Museum.

Allied to Glaucina erroraria Dyar, but the fore wings lack
the discal dot ; the claw on the fore tibiae is much smaller than
in erroraria, being concealed in the vestiture ; the epiphysis of
the fore leg is long and slender, exceeding the end of the tibia.

Stenaspilates apapinaria, n. sp.

Apex of fore wing pointed, the outer margin strongly scalloped;
hind wing with a distinct prominence at the end of vein 2. Brownish
ocherous, the fore wing shaded with red-brown; inner line dark
brown, bent beneath the costa, irregular below ; discal mark black, with
a little light powdering in its center; outer line preceded by a brown
shade, blackish, with a narrow outer whitish edge, nearly straight,
only slightly inflexed below the cell; an incomplete row of terminal
black dots somewhat removed from the margin. Hind wings with a
dark discal dot and extra-mesial line, the anal angle broadly irrorated
with brown; terminal dots as on fore wing. Expanse, 32 to 37 mm.

Four females, San Diego, Cal., May 27 and June 10, 1907.
The collector's name is not attached.

56 ENTOMOLOGICAL SOCIETY

Type. — No. 11699, U. S. National Museum.

Not very close to any of the species with which I am ac-
quainted. Nearest to zalissaria Walker, but the inner line is
considerably straighter than in that species.

Deilinia indurata, n. sp.

Fore wings not falcate, but the apex rectangular; cinereous, pale,
dark or of a reddish tint, uniformly rather sparsely irrorate with dark
scales over both wings; a small black discal point on each; inner
lines usually obsolete, in some specimens a portion of the inner line
shows, dark, not rigid, or a faint median line from the discal dot to
inner margin; subterminal line indicated by a series of dark blotches
edged without by white scales; a row of black separated terminal dots
on both wings. Hind wings with two dark bands more or less indi-
cated, especially towards inner margin. Beneath immaculate, pale,
the small discal dots repeated. Expanse, 26 to 27 mm.

Eight specimens, all males, San Diego, Cal., May 6, June 12,
27, 28, 1907 (W. S. Wright) ; Los Angeles Co., Cal. (D. W.
Coquillett) ; middle Cal. (Coll. Dr. W. Barnes) ; Placer Co.,
Cal. (A. Koebele) ; Seattle, Wash. (O. B. Johnson).

Type. — No. 11700, U. S. National Museum.

Differs from falcataria Pack, in having the hind wings as
much irrorated as the fore wings ; distinguished by the peculiar
submarginal line.

Selidosema jacumbaria, n. sp.

Male. — Pale lilaceous cinereous, the basal and terminal spaces laved
with rosy brown; lines black, distinct, broad, the inner arising on inner
margin close to base and running obliquely outward to middle of cell,
where it terminates ; outer line from middle of inner margin straight to
the end of the cell, thence slightly excurved, not quite attaining the
costa ; a very fine terminal black line, indented on the interspaces. Hind
wing similarly colored, except that there is no reddish color at the base ;
a narrow mesial line on the inner half of the wing, followed by a
strong, black, broad line that does not attain the apex. Beneath im-
maculate silky whitish. Expanse, 32 mm.

Female. — Slenderer and narrower-winged than the male. The rosy
color is reduced to a band following the outer line, being absent from
the base and margin ; a subterminal whitish scalloped line, edged
faintly with blackish within, which is scarcely legible in the male.
Lines narrow, filiform, black, contrasting strongly with the broad
smeared lines of the male, the outer line nearly straight.

Three males, one female, San Diego, Cal. (G. H. Field),

Type. — No. 11702, U. S. National Museum.

A large species, the wings bordered with rosy. The male
has the hind tibiae enlarged and with a strong groove on the
inner side, but there is no hair-pencil in it. In the three males
the black lines on the wings vary somewhat in width.

Selidosema aethalodaria, n. sp.

Dark purplish gray, the lines black, oblique; inner line from near
middle of costa, angled subcostally, running to inner margin near
base; discal dot black; outer line curved above, then straight and
oblique, reaching inner margin at about the middle; subterminal line
whitish, indistinct, stronger and wavy in the female. Hind wing more
grayish, except on inner margin crossed by two faint dark lines, den-
ticulate on the veins and traces of two beyond these at anal angle,
these two outer lines continued farther in the female than in the
male. Expanse, male 23 mm., female 22 mm.

red scales subdorsally, towards the tip. Wings shaped as in pistacearia
Packard, delicate green, marked with long, fine, white striations; two
lines on both wings, slender, not contrasted, slightly flexuous; costa
narrowly and the fringe of both wings red, fading to yellow at the
base of the fringe. Beneath silky whitish, the green showing faintly.
Expanse, 20 to 21 mm. Fore legs red, middle legs with red on the
outside, hind legs white. In the male the end of the hind tibia projects
beyond the end of the first tarsal joint, the tibia is enlarged, flattened

Family PYRALID^.

Subfamily CHRYSAUGIN.E.
Xantippe descansalis, n. sp.

Head, thorax, and fore wings lustrous warm red-brown, dark and
uniform, crossed by two very faint pale lines; the lines are so faint
that their position even is uncertain; the inner is near the base, the
outer at the outer third, both nearly straight. Hind wings subpellucid
dark fuscous ; abdomen dark fuscous. Expanse, 15 to 17 mm.

Three specimens, San Diego, Cal. (G. H. Field), Morena,
July 4 ; Descanso, July 7.

Type. — No. 11694, U. S. National Museum.

Subfamily PYRAUSTIN^E.
Glaphyria periculosalis, n. sp.

Fore wing pale stramineous, powdered and shaded with brown, most
distinctly over cell between inner line and discal mark and in terminal
area; lines brown, slender; basal line continuous, angled in the middle;
inner line angled on subcostal and in cell, thence evenly outcurved and
oblique to inner margin; outer line arcuate, minutely dentate, angled
inward at vein 2, outcurved below to inner margin ; discal mark two
opposed brown cusps followed by a white mark produced on its lower
angle to outer line; outer margin excavate below the apex, the fringe

Five specimens, San Diego, Cal., June 26, July 7 and 30
(G. H. Field) ; July 27 and August 8, 1907 (W. S. Wright).

Type. — No. 11693, U. S. National Museum.

This species does not belong in Homophysa Guen.
(= Glaphyria Hiibner ace. Fernald on Sir Geo. Hampson's
definition [Proc. Zool. Soc. Lond., 1898, p. 607]), as veins
10 and ii of fore wings are separate and I can not distinguish
pecten on the median vein of hind wings, but neither are they
in renicnlalis Zeller, which is included. The species would fall
in Symphysa except that the maxillary palpi are too short.
They reach only to the end of the second joint of the labial
palpi. According to the table it falls in Zinckenia (Hymenia
Hiibn. of our lists), but I do not like this association.

Metasia morenalis, n. sp.

Fore wing rather narrow, dark reddish brown, slightly bronzy; lines
very faint, pale, the inner obliterate, angled in the cell, oblique below;

slightly excurved on the median venules, denticulate. Hind wing pale,
subpellucid, slightly infuscated, distinctly so on the outer margin; a
curved dark punctiform line, close to margin from anal angle to middle
of wing, then becoming remote. Expanse, 20 to 22 mm.

Type. — No. 11688, U. S. National Museum.

Allied to A. lallatalis Hulst, but the outer line is not broken
and the hind wings are yellow. Moreover lallatalis is not an
Ambesa as the male antennae have a tuft of scales in the bend,
not a row of teeth.

— Dr. Howard spoke briefly upon certain new observations
on parasites now being made by Mr. W. F. Fiske, at the Massa-

OF WASHINGTON. 61

chusetts Laboratory for the introduction and acclimatization
of the European parasites of the gipsy moth and the brown-
tail moth.

— Mr. Barber exhibited specimens of the larvae, pupae, adults,
and work of a ptinid beetle, Dorcatoma dresdensis Herbst,
which he reared from fungi, principally Elfvingia fomentaria,
collected in Wisconsin. The other species of Dorcatoma
are supposed to breed in rotten wood. He also exhibited a
braconid parasite of the Dorcatoma and some photographs of
the various stages of the work. Mr. Schwarz said that now
was the time to do some fine work rearing fungus insects.
Early entomologists could not get fungi named, so many
valuable records were lost. Now, with so many mycologists
in the field, it should be an easy matter. Most of the insects
will probably be found to infest but a single host.

— Mr. Schwarz exhibited a specimen of the cerambycid
beetle, Adetus subellipticus Bates, which was reared by Mr.
Barber and himself from an apparently cucurbitaceous vine
at Panzos, Guatemala. This vine appeared to be in perfect
health when collected, and apparently was not injured by the
insect. He mentioned another instance where a cerambycid
develops in a green soft vine without apparently doing any
harm, Mr. D. L. Van Dine, of Honolulu, having sent in to
the Bureau of Entomology for determination numerous speci-
mens of an allied cerambycid, Apomccyna pcrtigera Thomp-
son, the larva of which infests the growing vines of water-
melons in the Hawaiian Islands. In both cases the vines
showed no outward sign of infestation. At Honolulu the
melons ripened on the infested vines without showing any
deterioration.

— The secretary read the following note, secured through
Mr. Busck:

MOSQUITOES DESTROYED BY THE NIGHTHAWK.

By ALLAN H. JENNINGS, Ancon, Canal Zone, Panama.

In May, 1887, while collecting on the island of New Provi-
dence, Bahamas, I had an opportunity of observing the mo-
squito-eating habit of the Cuban nighthawk.

62 ENTOMOLOGICAL SOCIETY

One afternoon about 4 o'clock a heavy thunderstorm came
up from the west accompanied by much rain. When the
storm passed by, about an hour before sunset, it was fol-
lowed by large numbers of birds of many species, but mainly
the smaller insectivorous birds, warblers, etc. They were
moving in the direction the storm had taken and were evidently
feeding as they went, though passing quite rapidly. Accom-
panying them was a number of Cuban nighthawks flying
rather'low at about the level of the tops of the somewhat low
trees fringing the coast at this point, or, in other words, at a
height of 25 or 30 feet.

Two of these were taken and on preparing the skins were
found to be exceedingly fat while the stomachs were distended
with mosquitoes, apparently a small species of Culex and re-
sembling the species that was most abundant in the locality.

The stomachs of a few warblers taken at the time were
also full of mosquitoes. Unfortunately I made no note of
stomach contents of other specimens of the species taken at
other times and points in the island.

— Mr. Schwarz exhibited a photograph of the tubes of a
common blue mud dauber from Plummers Island, Maryland,
probably Chalybion ccendeum L. He said that there were
various facts in the life history of the insect which were un-
known to him ; for instance, how many tubes are built by a
single female ; how the hissing noise made by the female while
constructing cells is caused ; whether the tachina fly, Pachy-
ophthalmus signatus Meig., which is reared from the tubes is
parasitic upon the wasp, on the spiders, or on the insects that
form its food, and how the fly emerges from the hard clay
tube.

Mr. Schwarz gave an interesting account of an observation
made by various members of the Washington Biologists' Field
Club last summer, of the manner in which one tachina fly
tried to enter one of the mud dauber tubes and how the parent
wasp defended its home against the intruder.

Doctor Howard said that all of the European records giv-
ing parasites of the mud daubers were wrong. In every case
the parasite was upon the insects carried in as food instead of
upon the wasp itself.

OF WASHINGTON. 63

Mr. Kraus said that he had marked one female wasp (Try-
poxylon albitarsis Fab.) with whiting and that she built five
tubes side by side. Mr. Schwarz said that in the case he ob-
served, two tubes were built by two wasps working together.

ON TWO NEW SPECIES OF PARASITES OF
ALEYRODID^.

By L. O. HOWARD.

In the course of the extensive investigations of the white
fly (Aleyrodes citri R. & H.) now going on in Florida under
the auspices of the Bureau of Entomology, as described by
Mr. Marlatt at a recent meeting of the Society ,a much atten-
tion is being paid to parasites. A. citri is as yet unparasitized,
but other Aleyrodidae are frequently killed in great numbers
by several species of parasites of different genera. An effort
is being made to induce the parasites of other species to
attack A. citri, and as many species as possible are being
introduced into Florida with this end in view. As yet none
of them has attacked A. citri. A recent series of slides re-
ceived from Dr. A. W. Morrill contain, among others, two
new species which are here described.

Subfamily APHELININ^: Howard.

Genus ENCARSIA Foerster.

Encarsia Foerster, Kleine Monographien, 1878, pp. 65-66. (Type,
Encarsia tricolor Foerster).

Including the single species here described, 14 species of
this genus have been recognized, of which one was described
by Foerster, one by Zehntner, and the remainder by the writer.
Like other parasites of Coccidae and Aleyrodidae, the genus is
now of wide distribution and if it were ever once localized it
is now too late to approximate its original range. It is now
represented in Europe, North America, Java, South Africa,
West Indies, and Mexico.

Twelve of the 14 species have been reared, and of these 12,
3 have come from diaspine scale-insects and the remaining 9
from Aleyrodidae. From the rearings so far made, the species

of this genus seem to be the most numerous and important of
the parasites of Aleyrodidse.

Encarsia variegata, n. sp.

Female. — Length, 0.64 mm.; expanse, 1.52 mm.; greatest width of
fore wing 0.28 mm. Eyes faintly hairy; head broad, eyes well sep-
arated; ocelli large, situated at angles of a right-angled triangle; an-
tennse nearly naked; first funicle joint slightly shorter than pedicel,
which is slightly swollen; second funicle joint longest, joints 3 and 4
and first joint of club subequal in length and each shorter than second
funicle joint; terminal joint of club slightly shorter than basal joint.
All tarsi S-jointed. Ovipositor well extruded. Color: Head and
thorax brown, except the mesoscutellum which is almost entirely silvery
white; antennal scape and all legs pallid and nearly translucent;
flagellum of antennae yellowish; eyes dark red; ocelli red, not so dark
as eyes; abdomen yellow, brighter above, but bordered on both sides
and behind with a brown band. Wings perfectly hyaline, with a densely
ciliate disc.

Type. — No. 11707, U. S. National Museum. Described
from 2 female specimens reared by Dr. A. W. Morrill at
Orlando, Fla., June 25, 1907, from Aleurodicus persece on
lemon leaves. It produces a curious dimorphism in its hosts,
according to Doctor Merrill's notes. Slide mounts sent by
Doctor Morrill to Washington show that a single pupa of the
parasite almost entirely fills the body of the host.

Genus ERETMOCERUS Haldeman.

Eretmocerus Hald., Amer. Journ. Science, Vol. ix, pp. no, in, May,
1850.

Doctor Haldeman, in the article just cited, describes among
other things Aleyrodes abutilonea and A. corni and erects the
new genus Amitus to contain A. aleurodinis, a parasite of the
larvae of Aleyrodes corni "of which it destroys a great many."
His new genus Eretmocerus, to contain E. corni, n. sp., was
based upon two mutilated females reared with this Amitus.
He suggested that the Eretmocerus may possibly be parasitic
in the body of the Amitus, making it a hyperparasite. Neither
genus nor species was refound until 1895, when the writer
described Eretmocerus calif ornicus (Tech. Ser. i, U. S. Dept.
Agric., Div. Ent., Revision of the Aphelininse of N. A., pp.
1 6, 17, figs, i and 3) from both sexes. This description was
drawn up from many male and female specimens reared in
June and October from an Aleyrodes on Quercus agrifolm at
Los Angeles, Cal. by D. Wy Coquillett. Mr. Coquillett ap-
parently reared nothing else from the Aleyrodes on this par-

ticular food plant, but he reared Pteroptrix fiavimedia How.,
Encarsia angelica How., and E. coquilletti How. from Aley-
rodes on different plants at about the same time and in the
same general locality, and there is nothing in his record to
negative the idea that E. californicus may be hyperparasitic.

from i male and I female reared by A. W. Morrill at Orlando,
Fla., from Aleyrodes coronata received from E. M. Ehrhorn,
Berkeley, Cal. From the same material were reared several
specimens of Prospalta aurantii How. and of a proctotrypid
which the writer determines with some hesitation as Amitus
aleurodinis Hald. So that here we have a situation almost
precisely similar to that described by Haldeman fifty-eight
years ago, and this species may very well prove to be a para-
site of the Amiius.

On looking over some old material a slide was found carry-
ing several specimens of the male of what is apparently this
species, bred Aug. 27, 1895, from an Aleyrodes on cotton from
Harrisville, Miss., together with a female of Encarsia co-
quill etti How.

A DECEPTIVE BEE.
By T. D. A. COCKERELL.

The time may come some day when our bee- fauna will be
so well known that the student can safely determine species
by their superficial appearance. At present, however, the sub-
ject is full of pitfalls, owing to the fact that specimens ap-
parently referable to well-known forms frequently prove upon
minute examination to be quite distinct, and undescribed.
Thus the determination of any collection takes much time
and care, even though it may consist exclusively of well-known
species. Just now, I have before me a bee received from
Mr. Nathan Banks with the label " Nomada modesta? ' As
I glanced at it, I thought it strange that so familiar and com-
mon a species should be identified with a query ; but upon
closer examination I at once saw that it was not typical mo-
desta, and after minute comparisons felt able to demonstrate
that it belonged to an entirely distinct species. I describe it
as follows:

Nomada mimula, n. sp.

Length about 10 mm. ; black with yellow markings ; legs red and
yellow, more or less stained with blackish ; abdomen finely and closely
but conspicuously punctured ; b. n. going some distance basad of t. m. ;
second s. m. very large, receiving first s. n. beyond the middle ; scu-
tellum strongly bigibbous. In size, color, and markings exactly like
N. modesta, except as follows :

Clypeus and labrum yellow; yellow lateral face-marks only going
a short distance above level of antennae ; scape stouter, yellow in front ;
third antennal joint conspicuously shorter titan fourth, being about as
long as fifth; a yellow spot at exact summit of eye (behind it in
modesta) ; punctures of mesothorax, though strong, much finer and
more even; lateral corners of mesothorax (just in front of tegulae)
yellow; metathorax black without yellow spots, but with a conspicuous
patch of white hair on each side; tegulse larger, ferruginous marked
with yellow, strongly punctured ; basal nervure as described above ;
anterior coxa: ^mth only a rudiment of a spine; anterior and middle
tibiae with much yellow at both ends; hind femora much suffused with
blackish, especially behind, and with a yellow spot at apex in front;
hind tibiae with more yellow than the others, the outer margin continu-
ously yellow; first abdominal segment more punctured laterally, the
band narrowly interrupted in the middle, and incised behind on each
side; fifth segment yellow, with a rounded black mark on each side,
and a little basal one in the middle, the silvery lunule not on a dark
patch; venter dark reddish, with yellow markings on segments 3 to 5.

OF WASHINGTON. 67

Falls Church, Va. (Nathan Banks). According to Robert-
son's arrangement this will not even fall in the same genus
with N. modesta; it belongs rather to his genus Xanthidium,
but rests uncomfortably there. I think there must be real
affinity with modesta; if not, and the case is simply one of
convergence, it is truly remarkable.

Two other bees collected by Mr. Banks show striking
peculiarities, which seem not to be of specific value:

(1) Colletes americanus Cress., female, Great Falls, Va.,
September n. Hair of thorax above bright orange ferrugi-
nous, like that of C. thoracicus and C. astecus. I cannot sepa-
rate the female from americanus; it is just possible that a
male might show differences.

(2) Colletes nudus Rob. Falls Church, Va., June 23, both
sexes at flowers of Ceanothus. One male, not otherwise differ-
ing, has the first recurrent nervure entering the second sub-
marginal cell at the basal corner, quite the same on both sides.
It seems to be the transversocubital nervure that has shifted.

At Falls Church, September 4, Mr. Banks took the female
of Epeolus vcrnoni(c Ckll., not hitherto described. It is con-
spicuously larger than that sex of E. pusillus, and has the
scutellum red.

Mr. Banks has taken a number of interesting species of
Nomada at Falls Church, including N. Carolina Ckll. (female
April 25), N. undulaticornis Ckll. (male April 18, at pussy
willow), N. placida Cress. (Sept. 7), N. perplexa Cress. (June,
at Ceanothus), N. ovata Rob., etc.

The 22 ist regular meeting was held at the Saengerbund

A NEW GENUS AND SPECIES OF MYMARID^.

[Hymenoptera, Chalcidoidea.]
By L. O. HOWARD.

The very minute and structurally interesting insects of the
family Mymaridae have attracted considerable attention, and
several well-known entomologists have written about their
curious structure and habits. Haliday, "Westwood, Forster,
and Xees ab Esenbeck have in their turn interested themselves
to a considerable extent in these most curious creatures ; Ash-
mead and the writer have described a few American forms,
and Mr. A. A. Girault is about to monograph the species
found in this country. So far as known, all of the species
are parasitic in the eggs of other insects, and as a conse-
quence they are extremely minute in size — in fact the family
has been stated by some writers to contain the most minute
of all insects.

Among a number of interesting parasitic Hymenoptera
reared by Dr. A. \V. Morrill in the course of his investiga-
tions, for the Bureau of Entomology of the U. S. Depart-
ment of Agriculture, on the white fly of the orange (Aleyrodes
citri R. & H.) at Orlando, Fla., and which Doctor Morrill
has sent to the writer for study, there occurs a very striking
mymarid, notable for its large size, which seems with little
doubt to belong to a genus hitherto uncharacterized.

Family MYMARID^ Ashmead.
Subfamily MYMARIXJE Howard.

Genus COSMOCOMOIDEA, n. gen.

Female. — General form rather slender. Head well rounded ; eyes
smooth, prominent, well separated; ocelli large, situated at angles of a
slightly obtuse-angled triangle, the lateral ocelli farther apart from
each other than from the eye margin; face with a very distinct trans-
verse carina above, with oblique carinse arising near each extremity
and extending towards mouth. Antennae (fig. n) inserted on middle
of face, bases widely separated, touching eye margin; n-jointed; scape
short, slightly rounded out below; pedicel short, obconical, a little
longer than wide; first funicle joint a little longer than pedicel but
much shorter than second, third, and fourth joints which decrease
gradually in length from 2 to 4; joints 5 to 8 also decrease gradually
in length; club obliquely truncate and somewhat longer than the three

OF WASHINGTON. 69

preceding funicle joints together. Pronotum prominent, well rounded,
posterior margin incised in the middle. Mesoscutum with well-marked
parapsidal furrows somewhat divergent anteriorly. Metanotum with
shallow median longitudinal sulcus. Abdomen petiolate, petiole nearly
as long as hind coxa; remainder of abdomen shorter than thorax,

FIG. ii. — Cosmocomoidea morrilli: Antenna of female.

narrow ovate. Forewings slender but well-rounded; submarginal vein
extending for a little more than a third of the wing length and ending
in a rounded knob ; hind wings excessively narrow.

Male. — Antennae n -jointed, all joints appearing flattened, subequal
in length, terminal joint shortest; all joints well separated and longer
than broad; scape short, only slightly longer than pedicel, rounded on
anterior border; pedicel with rounded margins.

The genus resembles in many respects Polynema Hal.
(=Cosmocoma F6rst.),but differs in the n-jointed antennae
of the female and in other respects. It derives its name, how-
ever, from the general resemblance.

COSMOCOMOIDEA MORRILLI, n. sp.

Female. — Length, 1.4 mm. Expanse, 3.9 mm. Greatest width of
fore wings, 0.4 mm. Greatest width of hind wings. 0.06 mm.

General surface of body smooth, shining; mesoscutellum faintly
aciculate-punctate ; general color very light brown, almost light yellow-
ish clay color; eyes black; ocelli reddish; a transverse black band across
the hinder portion of the mesoscutum; metascutum dusk}-; abdomen
with two transverse dusky bands at base and near middle. Pronotum
edged with brownish ; antennae black, except 5th and 6th segments of
funicle which are silvery white, and the scape and pedicel which are
honey-yellow. Tarsi and tibiae dark, the remainder of the legs con-
colorous with body; wings hyaline except for faint dusky patch beyond
stigma. These colors are darker in some individuals.

Male. — Measurements about the same. Antennae black. Body en-
tirely black, shining. All femora and coxae black; tibiae and tarsi
brownish. Wings perfectly hyaline.

Type. — Xo. 11856, U. S. National Museum. Described
from I male and 6 female specimens reared by Dr. A. YV.
Merrill at Orlando, Fla., March 29. 1907, from the eggs of
what is apparently a homopterous insect. According to Doc-
tor Merrill's notes, the eggs of the host insect seem to be de-

70 ENTOMOLOGICAL SOCIETY

posited just below the epidermis of the leaf of orange in a
parallel series and dusted over with a whitish powder. These
eggs are quite frequently found in citrus leaves and in the
leaves of Magnolia fuscata.

— Mr. Schwarz exhibited a series of the species of the
Scarabseid genus Dynastes, and pointed out the specific dif-
ferences. He said that Dynastes neptunus should be gener-
ically separated from the rest of the species, as was done
many years ago by Burmeister, who erected the genus Theo-
genes for this species. He said also that the large species
from Central America should not be quoted as Dynastes
hercules L. All of the specimens in the U. S. National Mu-
seum collections from Honduras belong to D. perseus Oliv.,
which is probably specifically different from D. hercules. The
National Museum collections contain also specimens of D.
alcides Fab., from British Honduras, which may be only a
form of D. perseus. The species lately described by Mr. A. H.
Verrill from the Island of Dominica as Dynastes vulcan is not
in the National Museum collection. From the description and
figure it appears to be closely allied to Dynastes alcides. A
number of fine photographs of the various species, made by
Mr. H. S. Barber, was exhibited (see Plates I, II).a

— In connection with Mr. Schwarz's remarks on Dynastes,
Mr. Barber exhibited the described species of the allied genus
Megasoma Kirby, and pointed out a specimen from Arizona
which no doubt represents a new species close to M. thersites
Lee. A single dead and mutilated specimen of this new
species was found by Hubbard and Schwarz on the road
between Tucson and Nogales.

— Mr. Webster stated that on April i, 1890, a number of
insects were taken from a crow's nest, among them a con-
siderable number of lepidopterous larvae of different sizes.
These were sent to the Bureau of Entomology on May 3 and

were determined, May 5, as probably those of a pyralid, hav-
ing very much the appearance of the larvae of Asopia. Be-
sides these larvae there was a number of specimens of a
beetle, Tenebrio molitor L., and also a number of cockroaches.
These were all found alive and among decaying leaves in the
bottom of the nest just beneath the lining. The crow's nest
was in a tree, about 30 feet from the ground, and contained at
the time six eggs, showing that it was occupied. While the
Tenebrio and the cockroaches might have been attracted to the
nest, possibly by a broken egg, it is somewhat difficult to
account for the presence of the larvae.

Mr. Busck stated that tineid larvse are often found in nests,
where they probably feed on the excrement. Pyralids might
have the same habit. Mr. Barber said there was quite a fauna
which was peculiar to bird's nests. He collected thirty or forty
species of beetles from one buzzard's nest. Some of them
he had found nowhere else. Mr. Schwarz said that a number
of Coleoptera were peculiar to birds' nests.

— Dr. Howard exhibited an interesting postcard which he
received from Prof. Antonio Berlese, of Florence, Italy. The
picture on the card, evidently a photograph of a microscope
slide, shows a nearly full-developed specimen of the chalcidid
parasite Prospalta berlesei How., which is about ready to
emerge from its host, Diaspis pentagona Targ. (Coccidae).
Doctor Howard said that the photograph was very interesting,
because it indicated that this American parasite is becoming
established in Italy, where it was first reared by Professor
Berlese from material sent from America. At that time Pro-
fessor Berlese recognized it as a new species, and returned it
to Doctor Howard, who described it.

Mr. Sanders said that another interesting point is, that while
the scale is not at all injurious to mulberry in this country, it
is so destructive to the mulberry in Italy that it threatens the
silk industry.

— Mr. Schwarz stated that last fall members of the Wash-
ington Biologists' Field Club made a practical test of Professor
Berlese's sifting machine, a description of which has been

72 ENTOMOLOGICAL SOCIETY

published by Doctor Howard.* At this trial, the machine did
not work satisfactorily. Only a few insects were trapped.
The most serious drawback is that a larger or smaller quantity
of fine dust goes along with each specimen that falls through
the funnel. This makes it much more difficult to pick out the
specimens than it would be to collect them in the first place
by the old-fashioned way.

— Mr. H. L. Frost, of the Cambridge Entomological So-
ciety, was invited to speak, and referred to what he considered
an interesting change of habit in the gipsy moth (Porthetria
dispar L.), discovered in the course of the campaign against
that pest. During the earlier years that the species was ob-
served, most of the larvae were on the lower limbs of the trees
and often crawled down the trunk, where they could be taken
by banding. Now most of them keep in the upper branches
and do not come to the bands. This makes the species more
difficult to combat.

Doctor Howard said that in his opinion this was not a
change in habit, but a case of the survival of the fittest. The
individuals that had the habit of living on the lower limbs and
crawling to the bands were exterminated, while those that
remained in the tops were left to increase and perpetuate the
race. Mr. Schwarz disagreed with this. He thought that it
might be a true change in habit, caused by the difference of
the summer climate in America. The much greater heat may
cause the larvae to seek the upper branches, where it is cooler.

Quite a discussion on the change of habit in insects followed.
Mr. Marlatt said he believed that certain races of a species
would acquire new food habits, or in other words that special
food-plant races of a species often develop. As examples of
this, he cited the following cases : The scale-insect Diaspis
pentagona Targ. has developed an American race that is in-
different to the mulberry, which is severely injured by that
species in Asia and Italy. Aspidiotus diffinis Newst. developed
a race on the U. S. Department of Agriculture grounds which
confined itself to a single variety of lilac, not even extending
to other varieties in close proximity. This habit was main-

a Entomological News, xvn, No. 2, pp. 49-53, February, 1906.

OF WASHINGTON. 73

tained for eight or ten years, until the host plant was destroyed.
These examples and others show that fairly fixed food races
are developed.

Mr. Webster agreed with Mr. Marlatt, and mentioned the
northern corn root-worm (Diabrotica longicornis Say) as an-
other illustration of an insect changing its food habits. There
is no doubt whatever that this species long ago inhabited the
country between Kansas and Nebraska and the Atlantic Coast,
but back in the seventies the beetle was by no means common
in many parts of Illinois and eastward. Mr. Webster remem-
bered perfectly the first specimen he ever found, about 1875,
in northern Illinois. It was afterwards found near Buffalo,
N. Y., on willows, by Reinecke, and in Nova Scotia by Har-
rington. Up to about 1860 Illinois and Iowa were essentially
wheat-growing States and corn was a minor crop. Soon after
that, conditions began to change, the wheat fields were diverted
to corn, and this crop was grown year after year successively
on the same land. It must have been some time between 1870
and 1880 that the species began to infest the corn fields, and
the first records we have of its destructive work on corn came
from the great corn-growing regions of Illinois and eastern
Iowa. Very soon afterwards the insect began to swarm in
the corn fields and the crop in some localities was badly dam-
aged and even wholly destroyed. Now this corn- feeding race,
if it may be so termed, began to diffuse itself to the eastward.
By 1885 it had become a serious enemy to corn in western
Indiana and by 1892 it had reached western Ohio ; by 1895 ^
had extended its ravages nearly half way across the State. Its
progress during these years in Ohio was illustrated by maps
in Bulletin 68 of the Ohio Agricultural Experiment Station.
In contrast with this condition in the western part of the
State, it may be stated that it was impossible to find it far
in advance of its destruction either as to locality or date. At
Wooster, in the northeastern-central part of the State, Mr.
Webster was unable to find it at all until 1902, when a single
beetle was found upon the blossom of a garden sunflower.
Now, its occurrence sparingly over this whole country long
prior to these days is beyond question, and not until this corn-

74 ENTOMOLOGICAL SOCIETY

feeding race originated in the immense corn fields of Illinois
and eastern Iowa did this gradual tidal wave sweep over and
reoccupy the eastern country, and it seems doubtful if, but
for this change of habit, we should ever have witnessed this
phenomenon. At present, the corn fields of northern Kansas
and southeastern Nebraska seem to be literally overrun with
this insect. During August and September it may be found
in myriads on the blossoms of a species of Helianthus that
grows abundantly in that section and also on goldenrod, and
it does not seem possible that it there has this corn-feeding
habit, else it would be impossible for farmers to grow this
cereal.

Mr. Webster said that a good illustration of the partial or
entire immunity of forest trees growing naturally in the woods
to the attacks of some insects that affect the same species of
tree when planted on lawns or along roadsides, is offered by
the walnut caterpillar, Datana integerrima G. & R. Year after
year this will defoliate walnut trees growing on lawns and
along streets and roadsides, but he did not remember of ever
having observed an infested tree growing up naturally in the
woods.

By E. J. KRAUS.

Among the insects found in lichens and decaying wood and
sometimes confused in collections with the true bark and wood-
boring Scolytidae are a number of species of Cis and other
Cioidse. Certain beautifully colored species occurring in the
United States and Cuba have heretofore been undescribed, and
at the suggestion of Mr. E. A. Schwarz and Dr. A. D. Hop-
kins, the writer has prepared the appended descriptions, based
on material in the U. S. National Museum, and that collected
at Virginia Beach, Va., by Doctor Hopkins.

OF WASHINGTON. 75

In his descriptions of new species belonging to this family,
Colonel Caseya gives especial attention to the clypeus and
clypeal margin as furnishing good taxonomic characters. The
structure referred to by him appears not to be the clypeus,
however, but to be made up of the epistoma as recognized by
Dietz,b Hopkins0, and others, together with the produced angles
of the front. The latter consist in an elevated ridge on the
anterior margin of the front, extending between the epistoma
and the eye on either side. The true clypeus is very small,
membranous or feebly chitinized, and more or less rudimentary.

The epistoma presents excellent taxonomic characters to be
recognized in the variations in its general shape and size, form,
and extension of the margins, its elevation or depression,
punctuation, surface characters, and further secondary sexual
modifications. In the frontal angles we may recognize equally
valuable characters.

The term glabrous, as used below, signifies the absence of
distinct pubescence or setae ; under high power each puncture
can be seen to bear a very small hair, invisible, or nearly so,
with an ordinary lens.

Genus CIS Latreille.

Antennae lo-jointed, third segment longer than fourth, the club
3-jointed; prosternum well developed before the coxae and without
distinct, prominent, median carina ; lateral edges of prothorax acute to
apex; body varying in form, setose or pubescent, the vestiture erect
and bristling; anterior tibiae finely produced and dentiform externally
at apex, sometimes simple ; head and prothorax strongly modified in the
males of some species, the epistoma and frontal angles more frequently
the only parts affected. There is also present in the males of some
species a deep circular fovea at the center of the first ventral segment
of abdomen.

Female. — Oval, glabrous, polished; prothorax piceous-black, slightly
rufous anteriorly; elytra straw-yellow, with broad, piceous-black band
either side the suture, expanded at base to the edges, much less so at
apex, this band perpendicularly interrupted at its middle by a broad,
transverse band of the same color, thus forming a Maltese cross on the
dorsum ; a very narrow dusky band also extends around the outer
edge of each elytron from base to apex. Abdomen fuscous, legs
amber, tibiae and tarsi darker. Head dark fuscous ; front convex,
minutely punctured ; epistoma flat, opaque, punctured, its anterior mar-
gin blending laterally with the produced angles of front which extend
on either side as broadly curved, entire elevations to the eye. Pro-
thorax broader than long, sides broadly rounded, anterior margin
constricted on either side, broadly rounded medially, punctures nu-
merous, fine, circular, deep, regular. Elytra twice as long as prothorax,

A FURTHER NOTE ON THE SLOTH MOTH.1

By HARRISON G. DYAR.

Since presenting the description of Cryptoses choloepi, the
moth breeding in the hair of the sloth, two additional speci-
mens were noted among the material recently collected by Mr.
Wm. Schaus. This material is being held for Mr. Schaus
to study when he returns from collecting, but in the present
instance I take the liberty of noticing these specimens in order
to present a description of the markings of the adult, which
were entirely illegible in the original specimens.

Fore wing long and narrow, the apex produced, but pointed; dark
bronzy brown, marked with longitudinal rays of shining pale ocherous,
as follows : Costa and internal margin, a broad stripe from the middle
of the cell to near the outer margin; a similar stripe on submedian
fold from base to margin, not discoloring the fringe; short, obscure
stripes between veins 2-3, 3-4, 4-5, and 7-8, the last stripe the
longest. Hind wing uniformly dark gray, the scaling somewhat thin
and semitransparent. Body parts clothed with short, shining, dark
gray-brown, hairy vestiture. Antennae of the male simple, smooth;
palpi porrect, down-curved, closely and minutely scaled; legs with
minute short vestiture of the same shining gray-brown color. Ex-
panse, 17-18 mm.

Two males, one marked " Tuis, Costa Rica, 2400 ft., July,
1907 " ; the other, " parasite on sloth."

After having learned the appearance of fresh specimens,
I discovered two such among Mr. Busck's material, captured
at light at Tabernilla, Panama.

Sir George Hampson kindly informs me that I have over-
looked a recent description of a sloth moth, Bradipodicola

hahneli Spiiler (Biol. Centralbl., xxvi, p. 690, 1906). Lord
Walsingham has from Staudinger one of the original speci-
mens taken by Hahnel in Brazil and, though in bad condition,
thinks it is certainly the same species as my Cryptoses cholccpi,
of which Mr. Schaus gave a specimen to the British Museum.
However, as the specimen of B. hahneli is in bad condition
and is a parasite on the other species of sloth, there is still a
chance that we may have two species of sloth moths. Sir
George refers the genus to the Schcenobiinse, on account of
the small tongue ; he gives " tongue absent " as the character
for that subfamily. I considered it to be present, but it is
certainly very small. He also sends me a reference by West-
wood to the occurrence of moths in the fur of the sloth (Trans.
Ent. Soc. London, 1877, p. 436), which appears to be the
earliest reference.

A NEW SATURNIAN MOTH FROM THE SOUTHWEST."

By HARRISON G. DYAR.

A specimen standing under the name Agapema galbina in
the National Museum collection for the last fourteen years
was long since recognized as a distinct species, but no mate to
it had ever been received. Now a male specimen has been
sent by Mr. Roberto Miiller from Mexico City, which, while
more brightly colored, appears to be certainly the same species.
It is accordingly characterized herewith :

Agapema homogena, n. sp.

Male. — Antennae very broadly, doubly bipectinated, ocher-yellow.
Body clothed with long blackish hair, paler at the tips of the segments,
the feet reddish. Fore wings grayish black, finely interspersed with
whitish hairs, the veins lined in carneous-ochraceous ; inner line angled
on the median vein, white, overspread with pink; discal mark ocellate,
black-edged and black-centered, containing an orange-ocherous annulus
and a blue crescent on its inner side; outer line white, rather broad
and straight, with a narrow inner pink edging; outer margin white,
shading to clay-color on the edge; a white subapical dash edged with
crimson below and outwardly. Hind wing similar, the inner line
wanting, the base broadly suffused with pink; discal mark with the
lumen wholly or nearly occluded; outer line indented slightly on the
veins; margin as on fore wings, the wing veins only obscurely pale-
lined. Expanse, 65 mm.

Institution.

OF WASHINGTON. 83

Female. — Similar to the male, but the lining of the veins much less
distinct, except on vein 7 and the costa; all the colors are somewhat
paler than in the male and the pink tint is wholly wanting, but this
may be due to age. In consequence the basal space appears darker
than the rest of the wing, while on the hind wing the base is whitish.
The ocellate discal spots are more widely centered and larger, that of
the hind wing having a distinct central lumen. Expanse, 78 mm.

One male, Mexico City, Mexico, March 1908 (R. Miiller) ;
one female, Fly Park, Chiricahua Mts., Arizona, 10,000 feet,
June 9, 1894 (U. S. Dept. Agriculture).

THREE NEW BEES OF THE GENUS NOMADA.

By T. D. A. COCKERELL.

Nomada mera, n. sp.

Female. — Length, about 10 mm. ; anterior wing, 8 mm. Red, rather
sparingly marked with black; abdomen above with bright lemon-yellow
markings, consisting of large pyriform lateral spots, the points di-
rected mesad, on segments 2 and 3, and a pair of rather large spots on
5; no yellow on segment 4, or on venter; no yellow whatever on head,
thorax, or legs; hair of face, cheeks, and sides of thorax, white; of
head above, and scutellum, ferruginous ; mandibles simple ; face with a
little black about ocelli and bases of antennae, and hind part of cheeks
black; antennas entirely red, normal, long, the flagellum stout; joint 3
about two-thirds length of 4; mesothorax very densely and strongly
punctured, with a single dark band ; scutellum elevated, bigibbous ;
metathorax with a median black band; tegulse bright ferruginous,
punctured ; wings with apical margin broadly fuscous ; stigma dark,
nervures black ; b. n. going far basad of t. m. ; second s. m. broad ;
anterior and middle femora black beneath at base ; hind femora mainly
black behind and beneath; first abdominal segment with a large black
mark springing from the base on each side; pubescent band on apex of
fifth segment narrow ; pygidial plate broad and subtruncate. Close to
N. cressonii Rob., but larger, and with no yellow on fourth abdominal
segment.

Salina, Boulder County, Colorado, April 14, 1907 (W. P.
Cockerell).

Nomada mera, var. a.

Female. — Differs by its paler coloration, the hind femora red behind,
with at most a slight blackish suffusion; abdomen paler, without any
evident blackish suffusion at sides of segments.

84 ENTOMOLOGICAL SOCIETY

Clementon, New Jersey, May 6 and June 3, 1900; two re-
ceived from Mr. Viereck, labelled N. bisignata maciilata. As
Robertson has shown, Nomad a maculata Cresson was based
on a mixture of species ; he has restricted the name to the
one with bidentate mandibles.

The specific name is derived from a Malay word meaning
red.

Nomada xanthura, n. sp.

Female.— Length about 9.5 mm. Red, with black markings; much
yellow on the abdomen above, but none beneath, and none on head,
thorax, or legs. Facial quadrangle about square; mandibles simple;
much black around bases of antennae, sending processes downwards
and upwards, the latter narrowly connecting with the black about the
ocelli; cheeks black posteriorly; antennae normal, long and stout, red,
except that the first four flagellar joints are strongly blackened above;
third joint barely shorter than fourth; mesothorax and metathorax
each with a median black stripe; scutellum moderately prominent;
postscutellum black, with two red marks in the middle; tegulae red;
wings strongly reddish, darker apically, and with a subapical clear spot;
b. n. going a short distance basad of t. m. ; third s. m. nearly as broad
above as second ; legs red, the femora black at base, hind femora much
blackened ; anterior coxce behind with distinct but very minute and
short spines; first abdominal segment conspicuously narrower than
second, black right across basally and without yellow; second with a
very broad, bright-yellow band, interrupted by a slender red line in the
middle; third with a basal yellow band, notched behind laterally;
fourth with less yellow; fifth zvith a very large quadrate yelloiv patch,
the surface of which is shining; band of tomentum on apex of fifth
narrow ; pygidial plate very broad and obtuse; venter red, with black
and dusky markings, the most conspicuous being a transverse black
mark at base of fifth segment ; the scanty hairs of venter are dark.
Allied to N. denticulata Rob., but easily separated by the characters
italicised (except the coxal spines, in which it resembles denticulata).

Sea Cliff, Long Island, N. Y., May (Nathan Banks).

Nomada (Gnathias) cornelliana, n. sp.

Male. — Length, about 10 mm. Abdomen long and narrow, rather
light red, the second and third segments each with a large yellow patch
on each side, but no other yellow on the abdomen ; clypeus yellow, a
little red above; lateral face marks consisting of rather broad bands
which follow the orbital margin to the top of the eye, but only the
lower part is yellow, the upper is red, and the red may extend to the
occiput, behind the ocelli; third antennal joint distinctly shorter than
fourth; scape clear red in front, black behind; flagellum clear red, the

first four joints with much black above; mesothorax black, with two
red marks ; varying to red with a broad black median band ; scutellum
red, prominent; postscutellum black marked with red, or red; meta-
thorax black, with two red spots in the enclosure; legs red, the femora
more or less blackened basally; wings strongly dusky at apex; stigma
ferruginous, nervures ferruginous to fuscous. I first received a speci-
men (Lehigh Gap) from Mr. Viereck, and placed it as a variety of
N. perplexa. A second example (Ithaca) appears to show that it is a
distinct species, not very close to perplexa. In my table of Gnathias
(Proc. Phila. Acad., 1903, p. 595) it runs to N. physura Ckll., from
Nevada. It is in all respects very close to physura, but a little larger,
with different lateral face-marks, and with the apical plate of abdomen
strongly notched. It is possible that it is a variety of N. bella, in which
the male has taken on much of the female coloration. The b. n., as
usual in Gnathias, goes a long distance basad of the t. m. ; the second
s. m. is ordinary. The venter of the abdomen is red suffused with
black; the base of the first dorsal segment is black. The pleura is
marked with red, varying to nearly all red.

Ithaca, New York (Nathan Banks) ; Lehigh Gap, Pa., June
26 (Viereck). The darker specimen, from Ithaca, is taken as
the type.

ADDITIONS TO THE LIST OF NORTH AMERICAN

GEOMETRID^:, WITH NOTES ON SOME

DESCRIBED SPECIES.

[Lepidoptera.]
By JOHN A. GROSSBECK.

The following embraces some of the species contained in
an interesting lot of Geometridse received from Dr. Harrison
G. Dyar for identification. In the case of Enphenolia palli-
m edia, n. sp., the main material came to me from Dr. Henry
Skinner, of the Academy of Natural Sciences, Philadelphia,
some time previous to the receipt of the specimens from the
National Museum. Most of the material came originally
from Dr. William Barnes, but all the types, except a few
which are retained in the author's collection, have been de-
posited in the National Museum.

Hydriomena manzanita Taylor.

Two specimens labelled Middle California. They are rather,
abraded and the ornamentation is so obscure that a different
species is suggested ; but a comparison with fresh examples

86 ENTOMOLOGICAL SOCIETY

of manzanlta in structure, color, and such markings as can be
made out fails absolutely to separate them. The species has
not been hitherto recorded off the Island of Vancouver, so the
present specimens considerably extend its known range.

Ccenocalpe carnata Pack.

Two males from Middle California. Both of these agree
more nearly with Packard's description of the species than
anything I have seen, and additional material may show that
the species generally passing in collections as carnata is dis-
tinct from it. Of the latter form I possess a series of 30
specimens from Stockton, Utah, and Fort Wingate, New
Mexico, and none of them shows so clearly the bright carneous
cross-bands, the outer of which contains a series of black ven-
ular dots.

Euphenolia pallimedia, n. sp.

Expanse, 13-14 mm. Front, vertex, except anterior portion, palpi,
thorax, and abdomen reddish-brown ; antennae and anterior part of
vertex pale yellow. Wings pale yellow, basal portion of primaries
reddish-brown, the outer edge of which is oblique, extending from
middle of costa or beyond, where it is more or less diffuse, to quite
far in on inner margin. Outer third of wing crossed by a sinuous
fascia of reddish-brown, broad on costa and becoming narrower toward
inner margin, and bounded internally by the extradiscal line which
is of a slightly deeper shade. A small portion of outer area not taken
up by this fascia is of a deeper yellow than the center of the wing
and the fringe is concolorous with it. Secondaries with outer third
occupied by a broad band of reddish-brown, limited internally by the
sinuous extradiscal line which can scarcely be separated from it, and
externally by the bases of the jellow fringe. Sometimes a broken line
of ground color runs through the band near its outer edge. Discal
points on both wings small, occasionally absent. Beneath, as above,
but the reddish-brown color a little fainter, especially that at the
base of the primaries, and the extradiscal lines are more prominent in
consequence.

Habitat. — Carr Canyon, Huachuca Mts., Cochise Co.,
Arizona, in August (Skinner) ; Wilgus, Cochise Co., Arizona
(Barnes).

Types. — Male and female in the Academy of Natural Sci-
ences, Philadelphia; co-types in the U. S. National Museum
(No. 11872), in Rutgers College, and in my own collection.

A not distant relative of Enphenolia skinncrata Gross., with
the same general type of maculation ; but the color of the
ornamentation is quite different in paUimcdia and the cross-

OF WASHINGTON. 87

lines are not nearly so well differentiated from the bordering
shades as in skinnerata.

Cymatophora tenebrosata Hulst.

One male and 3 females, Huachuca Mts., Arizona, and
Glenwood Springs, Colo. One specimen without locality,
labelled June 8-15.

The species was originally described from 5 examples of
each sex from various collections, but only a single type is now
in the Hulst collection at New Brunswick. The specimens
before me show considerable variation, ranging from a whitish-
gray ground with a single cross-line, the extradiscal, to a
ferruginous-gray ground with three distinct cross-lines.

Enypia griseata, n. sp.

Expanse, 30 mm. Head gray, at base of antennae superiorly, white;
upper portion of front brown, divided in the middle ; thorax with
mixed gray and white scales ; abdomen wholly whitish. Primaries
leaden gray over a whitish background, crossed by two narrow,
scalloped, blackish lines, most distinct on the veins. Intradiscal line
situated one-fourth out from base and consisting of four outward
scallops ; as a whole it is scarcely outcurved after the first bend from
costa. Extradiscal line originating on costa about one-sixth in from
apex and extending obliquely across the wing to the inner margin, end-
ing one-third in from the anal angle ; it consists of a series of inward
scallops, those between veins Mi and Ms and between the anal vein
and Cu2 being larger than the others and projecting farther inward.
Discal spot absent. Fringe checkered with blackish at the termination
of the veins. Secondaries whiter than primaries, especially on basal
two-thirds, and crossed by a single, inwardly-scalloped line, vaguely
indicated except on the veins and at inner margin. Fringe whitish,
marked at ends of veins by a distinct blackish spot. No discal
spots. Beneath whitish, powdered with grayish on costal two-thirds
of primaries and sparsely on costal and outer regions of secondaries.
Extradiscal line showing faintly on fore wings. Fringe as above.

Described from I male.

Habitat. — Las Vegas Hot Springs, New Mexico (Schwarz
& Barber).

Type. — No. 11873, U. S. National Museum.

This neat little species is allied to Enypia packardata Taylor.
It differs markedly, however, from that species in that the gray
scales which overlie the wings are evenly distributed and
not formed into transverse striations as in packardata. The
cross-lines, also, are narrower, not so deeply scalloped, and
there is no indication of a discal spot on any of the wings.

88 ENTOMOLOGICAL SOCIETY

The genus Enypia was erected by Hulst with venata Grt.
as its type and is diagnosed as possessing a hair pencil on the
hind tibia of the male. In griseata this character could not
be found and an examination of the type species shows that
it, too, is destitute of this structure, as are the remaining two
species, perangulata and packardata.

Meris alticola Hulst.

Two males from Las Vegas, New Mexico, without date.
The genus and species were described by Doctor Hulst from
a single female (Trans. Am. Ent. Soc., xxm, p. 348) and
until now the male had not been discovered. I append a
description of the male structure to supplement that of the
female in the above mentioned publication.

Palpi short, porrect; tongue developed; antennae bipectinate, the
pectinations clavate and gradually growing shorter to a simple apex;
patagia long haired ; abdomen untufted ; posterior femora fringed with
long hair, posterior tibiae scarcely swollen, with all spurs, grooved, but
destitute of hair pencil. Venation as in the female.

Therina hyalinaria, n. sp.

Expanse, male 20 mm.; female 35 mm. Head, palpi and anterior
part of thorax pale yellow; posterior part of thorax and abdomen
whitish. Both wings translucent; above and below uniformly whitish
save for a faint yellowish tinge along costae in male.

Described from I male and I female.
Habitat. — Southern Arizona (Poling).
This is a typical Therina and at once distinguished from its
congeners by the perfectly immaculate wings.
Type. — No. 11874, U. S. National Museum.

Gonodontis subcineraria, n. sp.

Expanse, 28-30 mm. Head whitish or brownish, sometimes the
front brown and the space between the antennae whitish, becoming
darker toward posterior edge of vertex. Thorax and abdomen brown-
ish-cinereous. Ground color of wings soiled-whitish, heavily overlaid
with brownish scales which take the form of transverse dashes closely
arranged, and, with the ground color, give the wings a mottled brown-
ish-cinereous appearance. In the female these dashes are not so
pronounced, but there is a liberal scattering of dark-brown atoms, which
are fewer in number in the male, over the wings. Primaries with two
rather narrow cross-lines of the same general color as the brownish
blotches ; these are indefinite in two of the specimens at hand, but
quite distinct in one male. The intradiscal line begins one-fourth out
on the costa and extends outward toward center of wing to the

OF WASHINGTON. 89

cubital vein, being slightly angled on the radial vein; from cubitus it
bends inward and runs obliquely with a gentle inward curve to inner
margin. The extradiscal line begins one-fourth in from apex, extends
outward in a straight line nearly to Mi, then bends sharply inward,
forming a right angle to the first part and runs in an almost straight
line to inner margin. The two lines divide the inner edge into three
equal parts. Discal spot brown, distinct, not very large. Secondaries
with a single, outwardly curved median line extending from inner edge
two-thirds across the wing, being scarcely traceable in the female.
Discal spot absent. Beneath soiled-whitish, with a faint yellowish
cast, the transverse dashes of above heavily reproduced, especially
on primaries and more profuse on outer third of both wings. Small
discal spots on both wings.

Described from 2 males and I female.

Habitat. — Southern Arizona (Poling).

Type. — No. 11875, U. S. National Museum.

This species falls in that section of Gonodontis which con-
tains distycharia Gn. and antidiscaria Walk, and is in fact
nearly related to the former. Like distycharia it appears sub-
ject to considerable va: ation, but may be readily separated by
the mottled wings and the absence of a pale yellow edging
with which both lines of distycharia are bordered.

Sabulodes amplicineraria Pears.

Three males, Southern Utah (Poling). In the absence of
a male the species was tentatively referred to Sabulodes by Mr.
Pearsall. Males now in hand show the reference to be correct.
Examples were taken not uncommonly during the season of
1907 by Mr. Tom Spalding at Stockton, Utah, in June, August,
and September.

Sabulodes ligata, n. sp.

Expanse, 33-37 mm. Head, thorax, and abdomen ochreous white.
Wings concolorous, well scattered over with blackish atoms, slightly
transverse in position, and with faint transverse buff colored dashes,
most evident on primaries between the two cross-lines. Intradiscal
line of primaries one-third to one-fourth out from base, brown or
ochreous in color and edged internally by a clear line of ground color;
it extends a little inwardly obliquely, scarcely curved, but angled out-
wardly on anal and cubital veins; costally this line is obsolete. Extra-
discal line of same color as intradiscal and bordered with a band of
ground color externally; it begins narrowly on costa less than 4 mm.
in from apex, curves inward a short distance below origin, and extends
straight or slightly outcurved to inner margin, ending over one-third
in from anal angle. Discal spot moderate in size, brown. Secondaries

with a single median line, continuous to and concolorous with the
extradiscal line of fore wings. Discal spot moderate in size, brown.
Beneath pale creamy yellow, with a scattering of brown atoms and with
the cross-lines of above feebly reflected. Discal spots present.

Described from 2 males.

Habitat. — Huachuca Mts., Arizona, in June.

Type. — No. 11876, U. S. National Museum,

The above describes more particularly the specimen I have
made type ; in the co-type the cross-lines are brown instead
of ochreous, the intradiscal line of primaries is located nearer
the discal spot, and the angles on the veins are scarcely obvious,
while the extradiscal line of both wings is a little outcurved.
There is no doubt, however, but that they are one species, as
similar differences occur throughout the group to which it
belongs.

Superficially the species resembles some of the paler var-
ieties of Caberodes confusaria Guen., but the angulated or
almost straight intradiscal line immediately separates it from
that species. It is, furthermore, a typical Sabulodes with
simple, flattened antennae in the male.

Sabulodes dyari, n. sp.

Expanse, 32 mm. Front and palpi reddish-brown; vertex, antennae,
thorax, and abdomen yellowish. Wings yellowish, with a deep-orange
cast, especially outwardly, and sparsely sprinkled over with minute,
blackish atoms. Two orange-colored lines of a medium breadth cross
the primaries, the intradiscal and extradiscal. The first of these begins
at the radial vein one-third out from base and extends in an almost
straight line to inner margin, being directed slightly outward; the
second begins very faintly on costa one-fourth in from apex and ex-
tends obliquely inward and without curve, except an almost imper-
ceptible one just below costa, to inner edge, the distance between them
near the costa about twice as great as that on the inner margin. Sub-
terminal line absent ; fringe orange. Discal spot brown, distinct, not
large. Secondaries with a single slightly curved line traversing the
center of the wing from inner margin to radial vein, where it ceases
abruptly. Discal spot small, faint, just within cross-line. Beneath,
both wings pale creamy-yellowish, darker on anterior two-thirds of
primaries and sparsely sprinkled over with brown atoms; discal spots
small, distinct. No indication of cross-lines.

Described from I male.

Habitat. — Huachuca Mts., Ariz., July 24-30.
Type. — No. 11877, U. S. National Museum.
Nearest to Sabulodes novellata Hulst, but the apex and an-
gulation of primaries on vein Mx are very much less acute

OF WASHINGTON. 91

than in that species and the intradiscal line is straighter, ap-
proaching the extradiscal toward inner margin. The deep
orange-yellow shade of the ground in dyari is probably never
attained by novellata.

Destutia, n. gen.

Palpi short, porrect, projecting a little beyond the front; tongue de-
veloped ; front rounded, slightly produced, smooth ; antennae of male
simple, naked, flattened; thorax and abdomen untufted; posterior
tibia of male thickened but without hair pencil, with two pairs of
spurs ; fore wings obtusely angled at M3, apex acute, falcate, twelve
veins, two accessory cells, R2 from end of cell, R3 and R* stemmed, R»
from cell, Mi from near base of second cell ; hind wings with seven
veins, subcosta separate from radius, radius not stalked with Mi.

This genus is allied to Sabulodcs Guen., differing chiefly in
the absence of the hair pencil on the hind tibia.
Type. — D. novata Gross.

Destutia novata, n. sp.

Expanse, 35-40 mm. Head, thorax, abdomen, and wings above
ochreous, the posterior wings somewhat paler than the anterior ones,
both wings more or less finely mottled by darker shadings of the same
general color. Two purplish-brown lines of moderate breadth cross the
primaries ; the intradiscal one- fourth out from the base is shortly
outcurved from costa, then runs almost straight to inner margin;
the extradiscal line leaves the costa 3 or 4 mm. from the apex (accord-
ing to size of moth), curves gently outward a short distance, then
faintly inwardly obliquely to inner edge. The two lines divide the
inner margin into three almost equal parts. The extradiscal line
in one specimen is edged externally by a narrow, incomplete, white
line which shows plainest near the costa and on the veins. Secon-
daries with a single extradiscal line, continuous to that of the fore
wings, obsolete at costa, slightly out and incurved, and ending a little
outward of the center of the inner margin. A brownish discal spot on
both wings, that of primaries being largest. Beneath somewhat paler
than above, sparsely brown speckled, especially along the costae. Discal
spots present, prominent. Transverse lines of above showing rather
strongly on primaries, much less so on secondaries.

Described from 2, males.

Habitat. — Huachuca Mts., Arizona, May 8-15.

A REVIEW OF THE NORTH AMERICAN CHRYSAUGIN.E.11

[Lepidoptera, Pyralidae.]
By HARRISON G. DYAR.

This subfamily of Pyralidas is represented in North America
by but few species, nearly every one of which belongs to a
separate genus. Several species had accumulated in the
collection of the National Museum which it was desirable to
place, and to do so I have made a cursory review of our
species, with the following result :

Genus GALASA Walker.

Galasa rubidana Walker.

This well-known species ranges from Florida and Texas to
New Hampshire and the Rocky Mountains. References may
be found in Hampson's work on the Chrysauginse (Proc. Zool.
Soc. London, 1897, pp. 633-692) and in Bulletin 52, U. S.
National Museum.

Genus TOSALE Walker.

Tosale oviplagalis Walker.

This species has a range similar to the preceding, but does
not extend so far to the North. Specimens are before me
from Florida, Texas, North Carolina, Maryland, Pennsylvania,
and Illinois. I have also a single female from southern Ari-
zona (Poling).

Genus CHALINITIS Ragonot.

Chalinitis olealis Ragonot.

I have no specimens of this species, but the venation given
by Hampson and the figure of Ragonot indicate a very dis-
tinct form.

Genus SALOBRENA Walker.

The synonymy of this genus is given wrongly in Bulletin
52 of the U. S. National Museum. (Ectoperia Zeller is prop-
erly a synonym of it as given by Hampson, but Clydonopteron
Riley should be distinct. Fernald is right in giving two
genera for tecDmce Riley and sincera Zeller, but he used the
wrong names.

Salobrena sincera Zeller.

My specimens are all from Texas, two originally collected
by Belfrage and others received later from Brownsville, col-
lected by Messrs. C. H. T. Townsend and H. S. Barber.

Genus CLYDONOPTERON Riley.

Clydonopteron tecomae Riley.

Besides Riley's types, I have a number of specimens from
the vicinity of Washington, D. C., and two from Agricultural
College, Mississippi, taken by Mr. Glenn W. Herrick. The
larvae feed in the seed pods of Tecoma. This is the only
species of North America Chrysauginae of which anything is
known of the early stages, with the exception of one new
species, hereinafter described.

94 ENTOMOLOGICAL SOCIETY

Genus XANTIPPIDES, n. gen.

Fore wing with vein 2 from well before the angle of the cell, 3 from
near the angle, 4-5 long-stalked, 6 shortly stalked with 7 to 9, 7 given
off before 9, 10 absent, n anastomosing with 12 and separating again;
hind wing with vein 2 from before the angle of the cell, 3 to 5 stalked,
6 from the upper angle of the cell, 7 anastomosing with 8. Palpi
small, upturned, not reaching the vertex.

Type. — Xantippe descansalis Dyar (Proc. Ent. Soc. Wash.,
X, Nos. 1-2, p. 58, 1908).

Xantippides descansalis Dyar.

Known to me only by the types from San Diego, California.

Genus ARTA Grote.

Arta statalis Grote.

Nearly all my specimens are from Arizona (Huachuca Mts.,
and Wilgus, Cochise County), all but one having come through
Doctor Barnes. One bears only the number 375, but I think
it is from Los Angeles, Cal. (D. W. Coquillett). The species
may prove to be a synonym of Parachma ochracealis Walker,
which comes from the same region and is like it in color and
markings, but differs in having veins 4 and 5 of the hind
wings coincident instead of stalked. This may be a case of
variability in venation only.

Arta olivalis Grote.

I have one specimen from Texas, Belfrage's original col-
lecting, and another taken on Plummers Island, Maryland, by
Mr. August Busck.

Genus AMESTRIA Ragonot.

Amestria oculiferalis Ragonot.

Not known to me, but should be easily recognizable from
Ragonot's figure.

Genus CAPHYS Walker.

Caphys bilinea Walker.

Known from Brazil, Venezuela, the West Indies, and Cen-
tral America ; it also extends into Arizona, whence I have
specimens labelled So. Arizona (Poling), and Nogales, Ari-
zona, July 7 and 30 (E. J. Oslar). References and synonymy
will be found in Hampson's paper (page 678) ; this is the first
record of this as a North American species. The specimens
before me vary remarkably in size.

OF WASHINGTON. 95

Genus ARTOPSIS, n. gen.

Fore wing with vein 2 from well before the angle of the cell, 3 to
5 stalked, 6 from below the upper angle of the cell, 7 to 10 stalked, 9
and 10 being on a common stalk in one specimen, separate in another,
II free, arising from the cell before apex; hind wing with vein 2 from
before the angle of the cell, 3 and 5 long-stalked, 4 absent, 6 from
the upper angle of the cell, 7 anastomosing with 8. Palpi small, slender,
upturned, not reaching vertex.

Artopsis borregalis, n. sp.

Fore wing ochraceous, overspread with purplish cinereous, leaving
two rather broad, distinct, curved, pale lines; hind wings pale, with a
faint, outer, curved, paler line. Expanse, 13 to 15 mm.

angle, 4 and 5 stalked, 6 from the upper angle of the cell, 7 to Q
stalked, 10 and n from the cell, free; hind wing with vein 2 from
well before the angle of the cell, veins 3 and 5 separate, 4 absent, 6
from the upper angle of the cell, 7 anastomosing with 8. Palpi in
the male slender, sharply upturned, and reaching above the vertex;
in the female porrect, the tip dependent, the second joint thickened
with scales above.

Satole ligniperdalis, n. sp.

Male with the costa enlarged at the base and folded over to form a
pouch as in To sale oviplagalis Walk. Blackish gray, the basal space
especially blackish; lines slender, white, distinct although very narrow,
both excurved mesially, parallel, dividing the wing into three areas of
nearly equal width ; faint indications of two darker rounded discal
dots, one in the cell and one at the end ; mesial space somewhat lighter
next to the inner line. Hind wing dark gray, the fringes dark, with
a double blackish line at their base. Coloration of the sexes alike.
Expanse, male, 18 mm. ; female, 22 mm.

Nine specimens, Portal, Arizona, bred from larvae boring
in the solid wood of "desert willow " (Chilopsis lincaris),
issued June 28, 1907 (U. S. Dept. Agriculture, Hopkins, U.

s. 5587).

Mr. Webb has handed me a vial containing two of the
larvae of this species. They are short and robust, whitish

96 ENTOMOLOGICAL SOCIETY

without markings, the head pale luteous, clypeus dark brown,
the mandibles, a spot on each side of clypeus, and antennae also
brown. The feet are very short, those of joints 7 to 10 repre-
sented by complete, rather broad ellipses of crochets, the last
pair by a line of crochets. Spiracles black-ringed. Tubercles

from Williams, Arizona, July 10 (H. S. Barber) which is
much larger than the males and has the outer line farther
from the margin.

Parachma ochracealis Walker.

I have specimens from Huachuca Mts. and Santa Rita Mts.,
Arizona (Dr. Barnes). (See remark under Arta statalis,
p. 94.)

Genus CONDYLOLOMIA Grote.

Condylolomia participalis Grote.

I have specimens from Cohasset, Mass. (O. Bryant), New
Brighton, Pa. (F. A. Merrick), Pittsburgh, Pa. (H. Engel),
and Plummers Island, Maryland (A. Busck).

A REVIEW OF THE NORTH AMERICAN PYRALIN^.*

[Lepidoptera, Pyralidse.]
By HARRISON G. DYAR.

Having had occasion to transfer the moths of this subfamily
to new drawers in anticipation of moving the National
Museum collection to the new building, I used the oppor-
tunity to rearrange them and determine the unnamed speci-
mens. The subfamily is represented by but few species in
our region, falling into six genera, separable as follows:

Institution.

OF WASHINGTON. 97

KEY TO THE GENERA OF NORTH AMERICAN

Median vein of hind wing without pecten of hairs on the upper side;
maxillary palpi filiform.
Palpi with the second and third joints upturned.

Proboscis absent or minute .......................... Aglossa.

Proboscis well developed.

Fore wings with vein 7 from 8 before 9 .......... Pyralis.

Fore wings with vein 7 from 8 after 9 ...... Hypsopygia.

Palpi rostriform and downcurved at extremity ...... Omphalocera.

Median vein of hind wing with pecten of hairs on upper side; max-
illary palpi triangularly scaled ............................. Uscodys.

Genus AGLOSSA Latreille.

Aglossa cuprealis Hiibner.

The species ranges from Maryland southward in the United
States. The specimens before me agree well with European
ones.

Lloyds, Md., July 10, 1907 (H. S. Barber) ; Plummers
Island, Maryland, June 3 (A. Busck) ; District of Columbia,
July 2, 1888 (T. Pergande) ; Pittsburg, Pa., June 8 and 18,

1906 (H. Engel) ; New Brighton, Pa., July 8, 1902 (H. D.
Merrick) ; "corn Pyralis, Treat;" Raleigh, N. C, June 28,

1907 (H. S. Brimley) ; Eufaula, Ala. (C. V. Riley).

Aglossa cuprina Zeller.

Sir Geo. Hampson places this species in Pyralis, but my
specimens have the tongue aborted. Possibly Sir George has
made a different identification. If I am correct the species
is easily to be told from cuprealis by the strong exsertion of
the inner line on submedian fold, which contains an elliptical
dark patch, looking like an elongated replica of the discal
mark.

Center Harbor, N. H. August 3, 1902 (H. G. Dyar) ; Plum-
mers Island, Md., June 5 to July 10 (Schwarz, Barber, Busck) ;
Pittsburg, Pa., July n, 1905 (H. Engel) ; Rhinebeck, N. Y.,
August 3, 1890 (H. G. Dyar) ; Tryon, N. C., August 2, 1903
(W. F. Fiske) ; " 4i6L " (C. V. Riley) ; St. Louis, Mo., Sep-
tember 8, 1904 (H. McElhose) ; Texas, July 7 (Belfrage).
The last specimen was submitted to Ragonot in 1884, who
identified it as Aglossa cuprealis, but wrongly, in my opinion.

Aglossa acallalis, n. sp.

A small, frail species with very long fringes; reddish, powdered with
black as in cuprina Zell., the lines blackish, broad, edged with pale

98 ENTOMOLOGICAL SOCIETY

yellowish, both mesially excurved and feebly dentate, but smooth and
even in comparison with the lines of the other species; fringes silky
gray. Hind wing pale grayish, with a darker irregular mesial line far
removed from the margin. Expanse, 16 to 20 mm.

Three specimens, Williams, Arizona, July 9 and 19 (H. S.
Barber) ; Ashfork, Arizona, June 18 (H. S. Barber).
Type. — No. 11924, U. S. National Museum.

Genus PYRALIS Linnaeus.

Pyralis farinalis Linnaeus.

Distributed throughout the United States.

Pyralis costiferalis Walker.

I have three specimens that agree well with Walker's de-
scription.

New Brighton, Pa., July 2, 1905 (H. D. Merrick) ; Pitts-
burg, Pa., June 23, 1905 (H. Engel) ; (C. V. Riley).

Pyralis disciferalis, n. sp.

Fore wing reddish ocherous, irrorate with blackish; costal edge
blackish except where cut by the lines ; discal spot large, blackish, sub-
quadrate; lines ocherous, slightly intensified on the costa, strongly
edged toward the median space with blackish, the inner slightly angled
on median vein and produced inward on submedian fold, the outer
mesially excurved, obscurely dentate; a row of black points at the base
of the fringe. Hind wing ocherous, reddish shaded, usually with an
extra mesial dark line and row of dots in the fringe. Expanse, 16
to 23 mm.

Twenty-four specimens, Plummers Island, Maryland, June
5 to August 1 8 (Schwarz, Busck, Barber, Warner) ; Pitts-
burg, Pa., July 20, 1906 (H. Engel) ; New Brighton, Pa.,
June 20, 1902 (H. D. Merrick) ; Chicago, 111. (A. Kwiat) ;
Travilah, Md. (F. C. Pratt) ; Black Jack Springs, Texas (W.
Barnes) ; Kerrville, Texas, May, 1900 (H. Lacy) ; Somerville,
S. C., April (R. Ottolengui).

Type. — No. 11925, U. S. National Museum.

Allied to P. costiferalis Walk., but the costal markings are
not more developed than the cross-lines. Especially the basal
costal mark does not exceed the subcostal vein, whereas in
costiferalis it extends to the median vein.

A specimen was sent to Prof. C. H. Fernald in 1901, but still
remains with him unidentified. I venture to enforce the
statute of limitations on a seven years basis and identify the
species myself.

Genus HYPSOPYGIA Hubner.

Hypsopygia costalis Fabricius.

Island, Maryland, June 5, 19 (Schwarz, Busck) ; Tryon, N. C,
May 13, 1903 (W. F. Fiske).

Herculia phcezalis, n. sp.

Dark brown with a vinous tint, fringes concolorous ; lines blackish
toward the median space, edged with yellowish outwardly, the inner
angled on median vein, the outer more distinct on costa, evenly ex-
curved mesially; a row of terminal blackish dashes nearly forming a
line. Hind wing with less vinous tint than the fore wing, but equally
dark, crossed by a curved whitish extra-mesial line, well removed
from the margin; fringe as on fore wing, with a black central line-
Beneath grayish, the terminal space paler and vinous shaded, the outer
common line repeated, dark, edged with pale, emphasized on the costa
of fore wing; a row of terminal triangular blackish dots. Expanse,
17 to 25 mm.

Thirteen specimens, Los Angeles Co., Cal., May (A.
Koebele) ; Los Angeles Co., Cal. (D. W. Coquillett) ; Santa
Monica, Cal. (J. J. Rivers).

Type. — No. 11927, U. S. National Museum.

Mr. Koebele's specimens are labelled " old branches of
Cupressus and fresh bark of orange;" Mr. Coquillett's bear
the letter " G," presumably referring to breeding notes.

A specimen of this species was sent to Prof. C. H. Fernald
in 1898, with permission to describe it, if new. He has never
reported on it, nor returned the specimen, and I trust he will
forgive me for taking the matter into my own hands after the
lapse of ten years.

Herculia cohortalis Grote.

This species is not before me. Described from Colorado
and apparently allied to the following.

Herculia thymetusalis Walker.

I have but a single specimen of this species, from the
Adirondack Mts., N. Y. (W. W. Hill).

Herculia binodulalis Zeller.

I have identified as this species two specimens from Kerr-
ville, Texas, November, 1906 (H. Lacy).

Herculia infimbrialis, n. sp.

Pale stramineous-ochraceous, the costa of fore wings darker, the
fringe concolorous, not yellow. The lines start from triangular yellow
costal blotches, and appear dark, their narrow vinous-brown edges

OF WASHINGTON. 101

being well relieved, the pale lines themselves scarcely distinguishable
from the ground color. Hind wing with two approximated dark lines.
Expanse, 27 mm.

Two females, Glenwood Springs, Colorado, July 16-23
(Wm. Barnes) ; Clear Creek, Col., July 18, 1904 (E. J. Oslar).

Type. — No. 11928, U. S. National Museum.

Near to binodulalis, but distinguished by the dark lines on
both wings.

Herculia himonialis Zeller.

I think this is not more than a variety of olinalis Guen. ; the
position of the lines on the hind wing seems to vary.

My specimens are mostly from Texas and Colorado, though
some from the Atlantic Coast region agree very well.

Herculia olinalis Guenee.

Common in the Atlantic Coast region from Rhode Island
to Texas, westward to the Mississippi valley. I have a speci-
men from Las Vegas Hot Springs, New Mexico (H. S.
Barber) that seems referable here rather than to himonialis,
although somewhat intermediate in the position of the lines.

Genus OMPHALOCERA Lederer.

Omphalocera cariosa Lederer.

I have specimens from Maryland, North Carolina, and
Alabama, the larvae on pawpaw ; the range probably extends
throughout the Mississippi Valley. The larva is black with
many white dots, a broad dull red dorsal and lateral stripe, the
former expanded on the centers of the segments.

Omphalocera dentosa Grote.

New Haven, Conn. (A. H. Verrill) ; Plummers Island, Mary-
land, June 6, 1902 (H. S. Barber) ; Ames, Iowa, June 6, 1896
(C. P. Gillette) ; Black Jack Springs, Texas (Wm. Barnes) ;
Dallas, Texas, May 31, 1896 (Dept. Agr. no. 6351), larvae on
Berberis. I have also a female from Durango, Colorado, that
is less vinous in tone and more darkly colored, perhaps a dis-
tinct species, but with the present material I do not venture to
separate it.

Larvae received from Mr. A. H. Verrill, which I think be-
long to this species, are black with many white dots, without
the red lines of cariosa.

Genus USCODYS. n. gen.

Median vein of the hind wings weakly pectinate on the upper side;
maxillary palpi broadly triangularly scaled; labial palpi long, porrect,

102 ENTOMOLOGICAL SOCIETY

drooping, the second joint with long scales below; tongue rudimentary.
Fore wing with veins 2 to 4 separate, 6 from near the upper angle
of the cell, 7 to 9 stalked, 10 and n from the cell, free. Hind wing
with the cell long, 2 to 5 separate, 6 and 7 from upper angle of the
cell, 8 running close to 7 but not anastomosing.

Type. — Anerastia cestalis Hulst (lately referred to Aglossa).

According to Sir G. F. Hampson's table, this genus would
fall in the Crambinae, but I have given more weight to the
venation than to the hair-pecten of the hind wing and scaling
of the maxillary palpi, which I think are more superficial char-
acters, and accordingly place the genus in the Pyralinse.

Uscodys atalis, n. sp.

Similar to cestalis Hulst, the markings of the fore wing being prac-
tically identical. The species is smaller, the color of the fore wings
brighter gray without a brown tint, the abdomen and hind wings
whitish scaled, not fuscous, the hind wing powdered with gray out-
wardly and with a blackish terminal line. Expanse, 20 to 22 mm.

The specimens have all come through the kindness of Mr.
Kearfott. His various attempts to name the species are at-
tested by a number of labels, which bear witness to the aberrant
character of this confusing species. One label reads " close to
Salebria, probably new," another " tails f probably," this last
attributed to Professor Fernald and presumably referring to
Crete's " bright purple " Botls tails from Alabama, through
what confusion it would be hard to say.

TWO NEW SPECIES OF NORTH AMERICAN TINGITID2E.

[Hemiptera — Heteroptera.]
(PLATE IV.)

By OTTO HEIDEMANN.

Acysta perseae, n. sp.

Colors sharply contrasting, shining black and yellowish white. Head
short, closely set into thorax, black except the two small, converging
spines in front and the narrow bucculae on the underside, which are
yellowish white; surface between eyes convex and somewhat rugulose,
a little impression at base near them; antenniferous tubercles blunt
but prominent. Eyes dark brown, strongly facetted. Antennae slender,
somewhat longer than distance from front of head to apex of posterior
portion of pronotum; basal joint not much longer than second, both only
slightly thicker than third; fourth joint dusky towards tip. Rostrum
yellowish, nearly reaching meso-metasternal suture. Thorax black
and shining, strongly punctured, moderately convex, transversely im-
pressed near front, thence the sides narrowing abruptly towards an-
terior margin, the latter with a narrow yellowish rim ; pronotum
without a hood and with only one median carina; membranous lateral
margins of thorax nearly obliterated, visible only as two very small
ear-like expansions near shoulders, translucent, yellowish white, bear-
ing a few minute round cells; tip of posterior portion of pronotum
of same color and closely reticulated. Elytra oblong-oval, much longer
than abdomen, somewhat narrowing towards apex, rounded at tip,
translucent, yellowish white, with a transverse black vitta near the
middle which becomes broadest at the discoidal areas, and beyond the
latter a few nervures inf uscated ; discoidal area apparently not closed
posteriorly by a raised nervure, barely wider than the subcostal area,
both closely reticulated with very small areoles ; costal margin about
as broad as the discoidal area, with rows of three or four areoles at
its widest part, these areoles increasing a little in size towards apex
of elytra. Wings attaining tip of abdomen, highly iridescent. Body
black, shining, sparingly pubescent. Rostral groove uninterrupted, the
marginal laminae not strongly raised, yellowish; metasternum black,
highly shining, transverse, flat. Last abdominal segment in the female
broadly rounded at apex; in the male, oblong, a small round fovea on
sides and strongly curved claspers at tip. Legs yellowish white, except
the claws, which are blackish. Length, 2 mm. ; width, 0.8 mm.

Described from two specimens, male and female. In ad-
dition I have examined some others, and a few larval forms.

Type (from Miami, Fla., female and male). — No. 11860,
U. S. National Museum. This neat little tingitid is most
nearly allied to G. C. Champion's Acysta3- intcrrupta, recorded
from Panama. The latter species, however, differs in having
three pronotal carinse and the membranous lateral margins
interrupted only in the middle; besides, the nervures in that
species closing the discoidal areas are well defined.

The U. S. National Museum possesses several specimens
from Florida which have been found infesting Per sea caro-
linensis and Per sea gratissima (alligator pear or avocado),
and other specimens coming from New Orleans, La. (La.
Exp. Sta. a. c. 457) are labeled " living on camphor trees
(C amphora officinalis}."

Eggs were examined on foliage of avocado twigs. They
were deposited on the underside of the leaves, standing up-
right in irregular rows ; they are of the usual tingitid egg
shape, of a dull yellow color with a white rim to the lid. Each
egg is more or less thickly covered by a dark, sticky secretion
from the insect.

Nymphs, probably in the fifth stage of their development. — Body
oblong-oval, dark yellowish, except towards base of abdomen where
the color becomes lighter with some scattered small reddish spots. On
each abdominal segment, on each side near the lateral margins arises
directly from the surface a peculiar prolongation in the shape of a
cylindrical process ; the two on the fourth and last segments are most
prominent. There are also some thicker and larger processes in the
middle of the first, fourth, fifth, and seventh segments dorsally; some
tubercles at each side of the wing pads ; two large processes placed near
together on the metanotum, and less prominent ones at each side of
thorax. The head carries three strong spines in front and two large
strongly curved horn-like processes at base, which are conspicuously
roughened. The processes at lateral margins of abdomen are yellowish-
white towards the end, a little thickened and rounded at tip, with a
few pores and short bristles; the others are dark brownish. Head
brown. The thorax shows some dark patches; the lateral margins
yellowish- white, nearly transparent; the wing pads, which extend to
the fifth abdominal segment, are entirely translucent except for a
blackish streak at base. Dorsal part of abdomen more or less speckled
with reddish and brown.

Leptobyrsa explanata, n. sp.

Body short, oval in the female, more elongate in the male, shining
black; membranous parts of pronotum and integument of elytra pale
yellowish, semitranslucent, nervures yellowish. Head rather small,
black, with three white frontal spines, two approaching each other,
the middle one comparatively stouter; besides, there are two other
more slender spines extending from behind the eyes towards front.
Antennae long, finely pilose, yellowish, the tips infuscated; two basal
joints slightly thicker than the following ones, first joint twice the
length of second, third little more than three times as long as fourth.
Bucculae yellowish, narrow, angulate and broader behind, the edge up-
turned a little. Pronotum transverse, feebly convex, coarsely punc-
tured, and shining black; in fresh specimens the sides of pronotum
are covered with a whitish film that also extends toward the under-
side at the sternum. Hood not much inflated, cristate and slightly
tapering towards front; covering the head, except the eyes, with quite
large areoles at the sides near top and a few smaller ones at lower part.
The three pronotal carinse yellowish, the median one strongly foli-
aceous, as high as crest of hood, rounded on top and slowly declining
towards apex of the triangular posterior portion of pronotum, with a
row of long, large areoles of which the middle ones are divided by a
few cross nervures and embrowned; outer carinse very low, only half
as long as the median carina, extending from base of hood to sides
of pronotal portion posteriorly; the triangular part of pronotum rather
short, yellowish and finely reticulated ; membranous pronotal margins
strongly rounded behind, reflexed, widening moderately at sides, nar-
rowing toward the neck and reaching the lower part of hood close to
the eyes, with two or three rows of average-sized areoles. Elytra ovate,
iridescent, extending one-half their length beyond abdomen, a little
less in the male; strongly rounded from base to apex, broadest behind
the middle; discoidal area pyriform and short, angularly raised at the
outer nervure, somewhat rounded at apex and broadly scooped out on
the upper surface, with three or four rows of quite large areoles at
the widest part. Subcostal area subvertical, wider than the discoidal
area, having about five rows of irregular small areoles, those of the
upper row much larger; costal area broadly expanded, with four or
five rows of very large, more or less irregular areoles, diminishing to
three and two rows at base. Surface of elytra very peculiarly undu-
lated, with two transverse, sharp impressions, and another at apex
formed by the outer nervure of subcostal area ; a light transverse fascia
on basal half. Median nervure of subcostal area strongly sinuate
towards tip of elytra; sutural area at inner part irregularly reticulated
with rows of some extremely large areoles. Entire margin of elytra,
lateral margins of pronotum, crest of hood, carinse, and most of the
nervures beset closely with long, very fine hairs. Rostral groove un-

interrupted, broad at mesosternum and metasternum, angularly closed
in front; rostrum reaching metasternum. Abdomen of female broadly
rounded at apex, in the male more elongate, the sides of genital seg-
ment sinuated ; at tip two strong claspers. Length, 3.6 mm. ; width of
each elytron across widest part, 1.4 mm.

Type (from Rock Creek, D. C., July 6, 1897, female and
male). — No. 9909, U. S. National Museum.

This new species seems to be most correctly placed in the
genus Leptobyrsa3-, which was founded by Stal on a single
speciesb from Rio Janeiro, Brazil. It agrees very well with
the diagnosis he has given of his genus. It also has much
affinity with the genus Stephanitis Stal, but the hood is com-
paratively smaller and the lateral carinas extend over the
whole length of pronotum, not abbreviated in front. Dr. C.
Bergc recorded another species from Argentina, South
America, and Dr. G. C. Championd described several new
species from Central America. Our species resembles two
species, Leptobyrsa steinii Stal and Leptobyrsa translucida
Champion ; from the first it differs in having the membranous
margins of pronotum less advanced in front, the sides not
straight but evenly rounded, and from the latter it can be
distinguished by the more prominent hood, also in having
two sharp impressions across the elytra.

This tingitid lives quite abundantly on the mountain laurel
(Kalmia latifolia) and on Rhododendron maximum. It has
been found up to the present time on the Atlantic side from
Florida as far north as Boston, Mass., and westward to Ohio.
The insect is recorded as injuring Rhododendron foliage.

The eggs are laid late in the fall, very differently from those
of all the other tingitid species with which I am acquainted.
Instead of being fastened on the surface of the leaves, un-
protected, as are those of the species living on oak, or being
hidden beneath the pubescence of the leaf like those of the
sycamore species, they are inserted entirely into the epider-
mis of the leaves, mostly at the sides of the main rib. In this
enclosure the eggs are protected during winter, and the
leaves of the laurel do not wither and fall off in this region
before the middle of June. Late in March, or in the earlier
part of April when the embryo insect in the egg begins to
grow, there appear on the underside of the leaf, right on
the midrib, some brownish spots. Later these spots show
little cracks, and thereby the tip of the egg is exposed; soon
the lid of the egg, which is somewhat oval in shape, is thrust
open and the young larva emerges from its confinement. The
egg is of a cylindrical-oval form, yellowish-white in color, and
about 0.4 mm. long.

The young brood and some unhatched eggs were found on
leaves of Kalmia latifolia in the woods near Brightwood, D. C.,
April 20, 1903. Some of the infested leaves of mountain
laurel were taken home and placed in glass jars so that the
hatching of the eggs and the development of the larval forms
might be studied. After three days some of the eggs opened
and the young larvae appeared; they are of a whitish color,
somewhat transparent at first, and without spines. After
taking plenty of nutrition the color turns into a greenish white ;
the body is more elongate, and the head comparatively very
large ; the antennae are long, nearly reaching end of abdomen,
thick, and beset with fine hairs.

Four days later the young nymphs shed their skins and
entered into the second stage of development. This time the
color darkens on the thorax and middle of abdomen ; the form
of the body has changed and become broader; the eyes are
large, showing five red facets ; at sides of each abdominal
segment small processes protrude, also a few prominent ones
on the first, third, fourth, and sixth segments at middle of
abdomen dorsally; others, still more prominent and stouter,
on the pronotum and mesonotum and five on the head, those
at base of head largest and bent forward; in this stage the
antennas and head appear smaller and less stout than in the
former stage.

The larvae began shedding the skin again on the 3d of
May, but any further observations on the other stages of de-
velopment came to a sudden stop; the insects died or dis-

108 ENTOMOLOGICAL SOCIETY

appeared in spite of new and fresh food. The last stage of
development of the nymph was examined at another time and
is described below :

Description of last stage nymph. — Body elongate-elliptical, yellowish-
white, pellucid, some brownish spots on inner side of the wing pads
basally and at apex; abdominal segments on the middle and all the
appendages or processes toward the tip brownish. Pronotum trans-
verse, lateral margins rounded ; hood, median carina, and triangular
posterior part of pronotum already indicated. Antennae as long as the
whole body, finely pilose, yellowish, tip of the two terminal joints
brownish. Wing pads reaching the third abdominal segment. Head
with five long processes, of which two at base of head are most
prominent and bent forward ; two smaller ones on a little eleva-
tion of median carina near together; very large processes on each
lateral margin of pronotum; two on the mesonotum and a single
one at middle of the first, third, fourth, and sixth dorsal segments of
abdomen ; another on each wing pad ; the processes on the lateral mar-
gins of abdomen are slightly smaller. These appendages or processes
are peculiarly shaped, cylindrical, narrowing toward the apex, the edge
of tip armed with two or three small sharp teeth ; there are also some
pores and short bristles on the surface of these processes visible by
high power magnification. Length, 2 mm.

In naming this species I gladly adopt the manuscript name
of Professor Uhler.

MAY 7, 1908.

The 222d regular meeting was held at the Saengerbund
Hall, 314 C Street, N. W. President Hopkins presided, and
there were present Messrs. Barber, Burke, Davis, Dyar, Ely,
Gahan, Heidemann, Hopkins, Kraus, Marsh, Patten, Piper,
Quaintance, Sanders, Schwarz, Ulke, Van Horn, and Webb,
members, and Messrs. Elsey and Bailey Willis, visitors.

— Mr. Sanders exhibited mounted specimens of the chalcidid
species Syntomaspis druparum Boh. and Megastigmus collaris
Boh. The larvae of Syntomaspis was found in November,
1907, in the seeds of a hybrid (Pear X Cratccgus) introduced
from Christiania, Norway, by the Bureau of Plant Industry.
The adults were reared May 2, 1908. The species was de-

scribed as Torymus dm p arum Boh. from specimens reared
from the mountain ash (Sorbus scandica). It has been re-
ported from Sweden, Germany, Crimea, and New York State.

The Megastigmus specimens were reared on May i, 1908,
from seeds of Rosa sp. sent from Peking, China, by Mr. F. N.
Meyer, agricultural explorer for the Bureau of Plant In-
dustry. The infested seeds were easily selected by their
brownish color. The species was originally described by
Boheman as presumably parasitic on Trypeta continua Meig.
in rose fruits from Saxony.

— Mr. Sanders also exhibited specimens of the coccid
Capulinia sallei Sign., on Eugenia tuberculata, from Santiago
de las Vegas, Cuba. These were collected by Mr. Wm. T.
Home and are particularly interesting because of the cob-web-
like waxy exudations. A very minute coccinellid, which was
determined by Mr. Schwarz as a new species of Scymnillus,
was reared from a large lot of specimens but no hymenopterous
parasites were obtained.

— Doctor Hopkins called attention to the record of the de-
struction of Douglas spruce seeds by Megastigmus pinus Par-
fitt and referred to his observations on Bruchophagus funebris
How., where a supposed hymenopterous parasite was discov-
ered to be an enemy of clover seed and not of a Bruchus or
any other insect living in the seed.

— In answer to a question by Professor Quaintance about the
sorghum seed crop, Professor Piper said that the cecidomyiid
Diplosis sorghicola Coq. destroyed the entire seed crop of
sorghum south of a certain definite line in Texas. This was
proved by bagging the heads at an early stage. When the
insects were eliminated in this manner, full heads of seed were
grown.

— The question by Mr. Willis as to what determines the
habitat of a species led to a spirited discussion. Mr. Willis
said the commonly accepted idea was that the temperature at
breeding time was the determining factor. Mr. Schwarz said
he doubted this and he did not believe that the cause or causes
that determine the range of species were known. Temperature
is probably only one of the many factors. Doctor Hopkins

110 ENTOMOLOGICAL SOCIETY

i

thought that there were two primary factors in the distribution
of a species — one, climate, the other, food. But while as a
general principle this appears to apply, there is sometimes a
great difference between species as affected by one or the other.
He stated that in his study of the Scolytidae and other forest
insects he found that some species of a genus may be restricted
to a given faunal zone regardless of the natural or artificial
distribution of the host, while others will be distributed over
several widely different zones of a continent and become
adapted to many hosts. Professor Piper said that sometimes
one factor determines and sometimes another. That tempera-
ture is not always the prime factor was well illustrated by an
observation on two species of spermophiles in Washington
State. The two species had definite ranges. When a disease
nearly exterminated one the other occupied the abandoned
range, proving that competition between the species was a
strong factor in determining their habitat.

— Mr. Heidemann exhibited specimens of Teraticoris hcrbat-
icus, a capsid described by Uhler from Labrador, and referred
to a lately published paper in Swedish by Prof. O. M. Renter,
" A North American Hemipter found in Norway," in which
it is stated that specimens found in Tromsoe, northern Norway,
proved to be in every detail identical with the species from
Labrador. It has nowhere else been found in the Palsearctic
region and the probability is that the North American species
was distributed over Greenland and Iceland into Norway, y

Doctor Hopkins stated that his observations on the Scolytidae
led him to believe that many so-called circumpolar species are
distinct and that often the supposed affinities are more ap-
parent than real, being due to the parallel development of
characters under similar environments. He stated further
that it was not impossible or even improbable that many forms
of life, common to two or more countries, which are recognized
as species, may have had independent origin from a common
primitive stock.

— Mr. Van Horn exhibited adult specimens of the elaterid
beetle Microrrhagus pectinatus Lee. and some interesting
larvae which may prove to be its immature stages. The larvae

OF WASHINGTON. Ill

are remarkable because of their peculiar mouthparts, which
are so fused as to be almost indistinguishable. They bore in
the decaying wood of oak, sycamore, and yellow poplar. Some
photographs, taken by Mr. Barber, of the larvae, were also
exhibited.

— Mr. Webster reported the finding of the clover root-borer
(Hylastinus obscurus Marsham) on the Pacific Coast, Mr.
Geo. I. Reeves having recently sent it from Vancouver, Wash.,
where it was seriously injuring red clover.

— Mr. Webster also reported the finding by Mr. Ainslie of
both males and egg-laying females of the spring grain-aphis
(Toxoptera graminum Rond.) in April of the present year.
The material from which the insects probably originated was
sent by Mr. E. O. G. Kelly from Leavenworth, Kans., late in
February ; the insects were kept on wheat in the office and con-
tinued to give birth to their young as usual. Some time late
in April Mr. Ainslie, on looking over the breeding jars, came
across eggs stuck on the inside of the glass with which the
infested wheat was covered. Almost immediately after, he
found the male and sexual female, some of the latter con-
taining both eggs and embryos within their abdomens. The
finding of the sexes in spring — and the males continue to
appear up to date, May 6 — is without a precedent, so far as he
was able to learn. These forms always occur in the fall, and
their presence, as here shown, indicates that they may thus
occur in the fields in spring in the far South.

blackish shade, the outer shade extending to the margin; a terminal
row of faint dark dots; fringe with a dark basal line. Hind wing
fuscous, darkest on the veins and marginal line, the fringe interlined
with dark at the base. Expanse, 16 mm.

One male, Burnet Co., Tex. (F. G. Schaupp), from Mr.
Kearfott.

Type. — No. 11849, U. S. National Museum.

Nearest to georgiella Hulst of any of the described species,
but not much like even that.

Salebria ademptandella, n. sp.

Fore wing light gray, peppered with black; lines black, strongly
relieved, the inner angled on subcostal and median veins, oblique and

OF WASHINGTON. 115

doubled below vein I ; discal dots black, rather large, conjoined ; a
pulverulent strigose black mark below the discal dots on submedian
fold; outer line black, geminate, whitish-filled, like the inner line, bent
inward opposite the cell, indented on submedian fold ; a row of con-
nected terminal dots. Hind wing pale fuscous, the fringe whitish,
lustrous. Expanse, 17 mm.

Two males, Kerrville, Tex., May and June, 1906 (H. Lacy).

Type. — No. 11705, U. S. National Museum.

Allied to 5. annulosella Rag., nubiferella Rag., turpidella
Rag., and tenebrosella Hulst, but of a brighter gray than all
these, with markings prettily contrasted.

Salebria rectistrigella, n. sp.

Fore wing dark, blackish gray; basal space filled in with blackish
except a white shade on costa inward from the inner line and an ob-
scure red-brown spot near the line below; inner line straight, a little
oblique, white, distinct, a dark wedge on the costa beyond it ; discal
dots black, separate, the upper one relieved in a white cloud that rests
on costa; outer line whitish, obscure, excurved mesially. Hind wing
whitish, narrowly fuscous along the costa and outer margin ; fringe
pale. Expanse, 18 mm.

One male, Kerrville, Tex., June, 1906 (H. Lacy).
Type. — No. 11706, U. S. National Museum.
A distinct species, that at first sight looks like Mineola
amplexella Ragonot.

Euzophera placidella, n. sp.

Pale gray, the body ocherous tinted. Fore wing whitish gray on the
costal half, nearly white on the costa, more irrorated with dark
scales below, the inner half shaded with ocherous gray; inner line
black, rather broad, erect, slightly curved, cut off before attaining
the costa; a single black discal spot, outer line oblique, close to the
margin and parallel to it except below vein 2, where it curves and
becomes perpendicular to inner margin, black with an outer white
border and a small black speck before apex. Hind wing whitish,
grayish tinted, subpellucid. Expanse, 18 mm.

One male, Yuma County, Arizona, Colorado Desert; from
Mr. Kearfott, I think, though this label has not been attached.

Type. — No. 11847, U. S. National Museum.

Entirely unlike any American species in the genus, looking
rather like a species of Honora. The smooth labial palpi with
long third joint and the long cell of the hind wings compel the
present reference.

116 ENTOMOLOGICAL SOCIETY

Subfamily ANERASTIIN^:.

Bandera binotella Zeller.

My specimens agree with Zeller's description better than
with Ragonot's figure. There is present in all a gray powdery
shading on the fore wings, leaving the ocherous ground-color
showing clearly only in two streaks on either side of vein i.
By Ragonot's figure and description the wings should be en-
tirely ocherous except for the costal markings and dots.
Whether Ragonot's specimens were in poor condition or
whether another species is involved may be left for later
decision.

Brownsville, Tex., May 21, 1904, and June 9, 1904 (H. S.
Barber) ; Five Mile Beach, N. J., July 2 (F. Haimbach).

Bandera cupidinella Hulst.

My specimens of this species, when in good condition, ap-
pear to have a white costal stripe owing to the width of the
white lining on the subcostal vein ; a lens shows that it does
not reach the base except on the vein. It does reach the
costal margin on outer half of the wing, and in this respect
my specimens do not agree with the descriptions of Hulst and
Ragonot, or the figure of the latter. As these authors appear
to have had but a single specimen, in which the markings may
not have been clearly apparent, I am inclined to retain the
identification of my specimens.

Twenty specimens are before me from Colorado from the
prairie at the foot of the Rocky Mountains, Denver and Fort
Collins. I have seen many more, now in the collections of
Doctor Barnes and Professor Gillette.

Bandera virginella, n. sp.

Allied to cupidinella, with the same pattern of markings and vena-
tion. It is smaller and whiter, the white of the veins spreading out,
so that the ocherous color shows only along submedian fold; the costa
is broadly white to base with a somewhat silvery sheen; rubbed speci-
mens look entirely silvery white like a miniature Crambus perlellus.
One specimen has a blackish dot on vein I at basal third, a small one
near the end of this vein, and a slight aggregation of scales above
on vein 2.

Six specimens, Pullman, Wash., July 8, 24, 31, August 3,
6, 10, 1898 (C. V. Piper). One specimen bears the number
463 of the Washington Experiment Station in red ink.

Type. — No. 11851, U. S. National Museum.

The specimen with the dots suggests binotella Zell., but it

OF WASHINGTON. 117

has not the venation of that species, veins 3 and 4 of fore
wings being well separated as in cupidinella Hulst.

Pectinigera (Cayuga) pamponerella, n. sp.

Palpi long, porrect, perfectly straight, the second joint conivex
above. Pale ocherous, shaded with vinous. Fore wing with the costa
broadly and evenly white, vinous shaded, the rest of the wing of the
ocherous color; a fine black line along subcostal vein and vein 6 in
one specimen followed by a faint blackish shading over the cell, the
other specimen without the black line and the shading fainter. Hind
wing faintly fuscous tinted in the dark specimen, whitish ocherous in
the other. Expanse, 27 mm.

Two males, Chimney Gulch, Golden, Colo., August 12, 1907
(E. J. Oslar), from Mr. F. Haimbach, who has kindly per-
mitted me to keep one type for the National Museum.

Type. — No. 11854, U. S. National Museum.

Similar to P. (C.) gemmatella Hulst, but the costal stripe
reaches the apex of the wing instead of terminating before
it, and the color is not so red.

Ollia holoponerella, n. sp.

Palpi long, porrect, gently and regularly downcurved. Ocherous, the
palpi grayish tinted on the outside. Fore wing yellowish ocherous,
with a few gray scales toward the outer margin, the costa broadly and
straightly white with a fine black line along the subcostal vein. Hind
wings whitish stramineous. Expanse, 27 mm.

One male, San Bernardino Ranch, Cochise Co., Arizona,
3750 ft., August (F. H. Snow).

Type. — No. 11855, U. S. National Museum.

This pattern of coloration is extremely common in the sub-
family, but most of the species so marked are smaller. The
size is the same as in the foregoing, Pectinigera pamponerella,
and I at first thought it to be the same species. However,
there is no tuft of scales discernible on the antennae, the palpi
are distinctly downcurved, the serrations of the antennae are
pointed teeth instead of quadrate plates (as in pamponerella),
while the color is ocherous, without any red tint.

Pectinigera (Cayuga) bistriatella Hulst.

Ragonot makes this a synonym to gemmatella Hulst, and
Doctor Hulst records it as a variety of the same in Bulletin
52, U. S. National Museum, presumably out of deference to
Ragonot's opinion ; but it is clearly distinct. I have no present
notes of the type, but from the description it must be closely
similar to Peoria discostrigella Dyar. In fact I have but little

118 ENTOMOLOGICAL SOCIETY

doubt that I have redescribed Doctor Hulst's species, the dif-
ference in generic reference being due to instabilities in the
venation. In my type, veins 4 and 5 are coincident on one
side, very long stalked on the other, but in additional specimens
the stalk of these veins is occasionally even rather short, vary-
ing on the two sides of the same specimen. My species was
described in these PROCEEDINGS (Vol. vi, p. 115, 1904) and
the variation in venation was noted, but I did not think to com-
pare with bistriatella, as that name was buried under gem-
matella, which it really does not resemble at all. The types
of discostrigella are females, so the antennal structure can not
be compared.

JUNE 4, 1908.

The 223d regular meeting was held at the Saengerbund Hall,
314 C street, N. W. President Hopkins presided, and there
were present Messrs. Ainslie, Barber, Burke, Crawford, Davis,
Dyar, Ely, Hall, Heidemann, Hopkins, Howard, Jones, Knab,
Marsh, Patten, Ouaintance, Sanders, Sasscer, Schwarz, Ulke,
Van Horn, and Webb, members, and Messrs. Shonts, Smyth,
and Snodgrass, visitors.

— Doctor Howard presented a paper entitled " Some Notes
of Interest, "a in which he discussed, (i) the finding of tick
parasites, (2) the introduction of a parasite of the elm leaf-
beetle, and (3) an explanation of a fly-paper experiment. Mr.
Knab asked if the elm tree is ever killed by the elm leaf-beetle.
Doctor Howard replied that in exceptional cases, where a
drought followed the defoliation, the trees were killed.

— Mr. Webb exhibited a species of Pogonocherus occurring
on Pinus edulis and P. jeffreyi in Arizona, which has since been
described by Mr. Chas. Schaeffer as Pogonocherus calif ornicus.

— Doctor Hopkins then read a paper entitled " Another Defi-
nition of Species." It provoked spirited discussion on the part
of Messrs. Schwarz, Hopkins, Dyar, and Barber.

— After the meeting Mr. Barber exhibited living specimens,

both males and females, of the beetle Phengodes laticollis Lee.,
which he had quite recently collected on Plummers Island,
Maryland (near Washington, D. C.), and the members had
not only an opportunity to admire the luminosity of the larvi-
form females, but also to witness the mating of the sexes,
which are so dissimilar in form, and the fierce combats of the
males among themselves.

OCTOBER i, 1908.

The 224th regular meeting was held at the Saengerbund
Hall, 314 C street, N. W., the Society being entertained there
by Mr. E. A. Schwarz. President Hopkins presided, and
there were present Messrs. Banks, Barber, Burke, Caudell,
Crawford, Currie, Ely, Hall, Heidemann, Hopkins, Jones,
Knab, Marlatt, Patten, Ouaintance, Sanders, Sasscer, Schwarz,
Van Horn, Webb, and Webster, members, and Messrs. Hyslop,
Jennings, Leister, Lloyd, McAtee, McMillan, Overton, Peairs,
Russell, Smyth, and Wellman, visitors.

— Under the title '" Some Present Deciduous-fruit Insect
Problems," Mr. Ouaintance spoke of a recent trip to the Pacific
Coast to investigate pear-thrips conditions; and also of a trip
to Orcas Island, Puget Sound, Washington, to investigate the
so-called service-berry moth (Argyresthia conjugella Zeller).

Referring to the pear thrips, Mr. Quaintance stated that the
so-called pear thrips (Enthrips pyri Daniel) first came to
notice in the spring of 1904 in the Santa Clara Valley in Cali-
fornia. Since its first appearance, its injuries have constantly
increased, and it has now spread to the principal deciduous-
fruit growing sections in the San Francisco Bay region. The
losses brought about by the pear thrips the past year have been
perhaps not less than half a million dollars.

The pear thrips was first investigated in 1904 by Mr.
Dudley Moulton, at that time entomologist of Santa Clara
County, and a fairly complete account of it was published
in a bulletin from the office of the state commissioner of
horticulture. The increased destructiveness of the thrips led

OF WASHINGTON. 121

to provision by Congress for an investigation of the insect by
the Bureau of Entomology of the U. S. Department of Agri-
culture, and Mr. Moulton, who in the meantime had been
employed by the bureau, was assigned to the work, beginning
July i, 1907, with headquarters at San Jose, Cal.

The pear thrips attacks various deciduous fruits, as almond,
apricot, peach, prune, cherry, pear, apple, etc. The life history
is briefly as follows : Early in the spring, as in late February
or early March, the adult thrips begin to make their appearance
from the soil, at once attacking the opening buds or blossoms,
and by their feeding soon cause these to blight, literally nipping
the fruit crop in the bud. Oviposition occurs soon after emer-
gence, the eggs being placed in soft tissues, especially in fruit
and leaf stems or in the midribs. The young larvae feed upon
the tender tissues of the leaf or flower, requiring some three
or four weeks to reach their full size. They then leave the
plants and work their way below the soil from 3 to 4 or even
10 to 12 inches, depending upon whether this is hard or soft.
In the soil the thrips larvae construct small oblong cells where
they remain the balance of the season. In late fall and early
winter, transformation to the pupa stage occurs, from which
the adults develop to appear above ground about the time fruit
trees are beginning to bloom in the spring. There is thus but
one generation each year, and the insect spends practically ten
months in the ground.

The pear thrips has proved to be a very difficult insect to
combat, and its practical control has not yet been determined.
The Bureau of Entomology is carrying out extensive experi-
ments and demonstrations in spraying in the infested territory
and is also testing over large areas the possibility of destroying
the larvae or pupae in the ground by cultivation or other
methods of soil treatment. Of many sprays tested, a pro-
prietary tobacco extract and a distillate emulsion have proved
most efficient. Spraying must be directed largely against the
larvae feeding on the more exposed portions of the plant. Of
the various fruits attacked, pears and prunes suffer most,
from the fact that the thrips are out in large numbers just
when the buds of these fruits are beginning to swell, and these

122 ENTOMOLOGICAL SOCIETY

are promptly infested and destroyed, usually before the
blossoms expand.

In regard to the service-berry moth (Argyresthia conjugella
Zeller), Mr. Quaintance said he had no difficulty in finding
larvae of this species in considerable numbers in apples in
orchards on Orcas Island. The larvae at this time (late
August) were mostly full grown and occurred in the blossom
end of apples, feeding in a cavity there excavated, while many
individuals had penetrated to the seeds, which had been more
or less hollowed out. The larva very much resembles the lesser
apple worm (Enarmonia prunivora Walsh) and might readily
be mistaken for it. In one orchard examined, approximately
75 per cent of the fruit was infested. In others investigated
farther back from the shore-line, and which had evidently been
sprayed, the injury was much less.

Mr. Quaintance also called attention to a recent account of
the service-berry moth by Professor Sven Lampa, and exhibited
a translation of this paper which Mr. C. B. Hardenberg had
kindly prepared for him. It was not thought that this service-
berry moth would prove to be especially important in orchards
regularly sprayed for the codling moth, since its habit of feed-
ing within the calyx cavity in a way very similar to the codling
moth would render effective arsenical treatments.

It was found, during the course of a day's examination of
apple orchards in the Orcas Island region, that the codling
moth had not yet reached that territory.

Attention was called to an investigation in progress, in north-
ern Ohio, of two barkbeetles, Scolytus riigulosus Ratz. and
Phlceotribus liminaris Harris, which have become unusually
abundant, infesting principally the peach, but also attacking
other deciduous fruit trees. This work was undertaken in
cooperation with the Ohio agricultural experiment station, and
Mr. H. F. Wilson, working for the Bureau of Entomology,
spent the entire season in the field, with headquarters at Lake-
side, Ohio. Considerable time was being devoted by Mr. Wil-
son to life-history studies of the two species, and extensive
tests of various tree washes and other remedial operations
were in progress. Photographs were shown of an orchard

OF WASHINGTON. 123

being dug out and destroyed on account of the injuries of these
insects, and of the orchard in which the tests of washes were
being made.

In the discussion which followed, Doctor Hopkins stated
that it was remarkable that the attack of Scolytus rugulosus
on healthy trees should be so extensive, since the normal habit
of this barkbeetle is to infest trees weakened or dying from
some other cause. Its abundance indicates that some favorable
conditions for its abnormal increase have prevailed and that its
destructive attack on the living trees is due to this fact. The
continuation of the destructive attack depends on the continua-
tion of the insect in excessive abundance, otherwise it could
not overcome the resistance of the healthy tree. Therefore any
thing that will reduce its numbers to a point where it can not
kill the trees will bring it under control.

Professor Webster said that many of the orchards in north-
ern Ohio have been in a weakened condition for about eight
years, due to bad treatment and neglect.

— Mr. Marlatt talked on " Irish Notes and Insects," and gave
an interesting account of his vacation trip and travels in Ireland
the past summer. He made special mention of the number of
peat bogs, and described their appearance and method of
formation. He also gave an account of the meeting of the
British Association for the Advancement of Science, which
he attended while in Dublin.

Mr. Schwarz said that the fauna of the peat bogs is quite
peculiar, and named a number of European Coleoptera found
exclusively in or around peat bogs. He said that very little
had been done on the fauna of the peat bogs of America, and
that this would be an excellent subject for study by some young
entomologist.

Mr. Banks stated that many mites are peculiar to peat bogs.
Prof. Halbert has described a considerable number of Hy-
drachnidae from Ireland, and states that the water-mite fauna
of the peat bogs is very large.

— An interesting account of a beetle which destroys stored
plants of the " guayule " rubber (Parthcninin arcjcntatnin ) was
given by Dr. Francis E. Lloyd. He said that when the plant

124 ENTOMOLOGICAL SOCIETY

is stored the beetle soon attacks and riddles the stems, trans-
forming them into a mass of dust-like borings. This does not
destroy the rubber, but fills it so full of small fibres of wood,
from which it can not be separated, that it is worthless. About
20 per cent is lost in this manner. The insect loses its eco-
nomic importance, however, because it has been found im-
practical for other reasons to store the plant for any length
of time.

In the discussion Doctor Hopkins stated that the beetle
mentioned by Doctor Lloyd is evidently Pityophthorns nigri-
cans Blandf., which has also been reported to the Bureau of
Entomology by H. Pittier, who found it injuring the same plant
at Correen, Coahuila, Mexico. The insect is of special interest
because of its habit of attacking a plant of such commercial
value, and on account of its being the largest representative
of the division of the genus to which it belongs. The species
of Pityophthorus fall into two divisions, which are distin-
guished by both morphologic and bionomic characters ; those of
one infest coniferous trees only, while those of the other, to
which this species belongs, infest only the broad-leaved plants
and trees. The rubber-plant beetle evidently attacks the plant
after it is dead, or soon after it has been cut and, as has been
shown by the specimens in the forest-insect collection of the
Bureau of Entomology, may continue to breed in the same bark
and wood for several years. It is evident that the prompt
utilization of the plant for the manufacture of rubber within a
few days after it is cut would prevent all losses from this
source.

Mr. Schwarz called attention to the fact that the jalap
(Ipomcca purga) of commerce is more valuable when it has
been eaten by the jalap beetle (Ernoporns [Coccotrypcs]
jalap pee Letz.), a scolytid. For some reason, its medicinal
qualities are improved by being eaten by the beetle.

SPECIAL MEETING, OCTOBER 19, 1908.

A special meeting of the Society was held in room 6, Bureau
of Entomology, U. S. Department of Agriculture, to take ap-

OF WASHINGTON. 125

propriate action on the death of William H. Ashmead, a promi-
nent member and former president.

President Hopkins presided and there were present Messrs.
Banks, Barber, Burgess, Burke, Caudell, demons, Coquillett,
Crawford, Currie, Heidemann, Hopkins, Howard, Knab,
Kraus, Marlatt, Ouaintance, Russell, Sanders, Sasscer,
Schwarz, Snodgrass, Strauss, Van Horn, and Webb.

Doctor Howard moved that the chair appoint a committee
of three to draft the necessary resolutions. This was seconded
by Mr. Schwarz and carried. Messrs. Howard, Schwarz, and
Banks were appointed, and reported the following resolutions
which were ordered to be sent to the family of the deceased
and to be printed in the PROCEEDINGS of the Society :

WHEREAS, the Entomological Society of Washington has
lost by death its former President, William Harris Ashmead.
and

WHEREAS, Doctor Ashmead was one of the oldest members
of the Society and had, by his extraordinary activity and genius
in entomological investigations, especially of a systematic
character, contributed very greatly to the interest of the meet-
ings of the Society and to the importance of its publications,
and

WHEREAS,, his warm-hearted enthusiasm and his kindly help-
ful character had brought him to occupy a high place in the
affections of all of the members of the Society, therefore,

Be it resolved, that in the death of Doctor Ashmead the
Society has suffered a very great loss ; that the field of syste-
matic entomology has been deprived of one of its most promi-
nent workers, and that the development of that branch of
science not only in this country but throughout the world will
be retarded by his untimely end. And

Be it further resolved, that the members of the Society who
loved and admired him will always profit by the memory of
his indefatigable energy and his untiring effort to bring order
out of the chaos of described and undescribed forms.

Be it further resolved, that a committee be appointed to
prepare a sketch of Doctor Ashmead's life (including bibliog-
raphy) for publication in the PROCEEDINGS of this Society,

126 ENTOMOLOGICAL SOCIETY

and that copies of these resolutions be sent, with an expression

of sincere sympathy, to his family.

L. O. HOWARD,
E. A. SCHWARZ,
N. BANKS.

President Hopkins announced that he had appointed Doctor
Howard and Messrs. Crawford and Banks a committee to pre-
pare a biographical sketch of the late Dr. Wm. H. Ashmead,
and a bibliography of his writings.

Extended remarks were made on the character and work of
Doctor Ashmead by Doctor Howard and Messrs. Schwarz,
Crawford, Coquillett, Currie, Banks, Hopkins, Caudell, and
Marlatt. All testified to his indefatigable energy and enthusi-
asm, to the way in which he inspired young entomologists, and
to the great value of his work.

WILLIAM HARRIS ASHMEAD.

William Harris Ashmead, assistant curator, Division of In-
sects, United States National Museum, one of the foremost
American workers in systematic entomology, died in Washing-
ton, October 17, 1908, after a lingering illness. Although his
death had been expected for some months, owing to the char-
acter of the malady that laid him low, it was none the less a
great shock to his wide circle of friends among the scientific
community of Washington and to the members of the Ento-
mological Society of Washington, of which he had been presi-
dent.

Doctor Ashmead was born in Philadelphia, September 19,
1855. He was the son of Captain Albert Ashmead and Eliza-
beth (Graham) Ashmead, and came of fine old colonial ances-
try on both sides. He was educated in the private and public
schools of Philadelphia, and early in life entered the publish-
ing house of J. B. Lippincott Company, of that city. Some
years later he went to Jacksonville, Fla., and with his brother
established a printing house for the publication of agricultural

WILLIAM HARRIS ASHMEAD.

OF WASHINGTON. 127

books and other matter. He founded an agricultural weekly,
and a daily entitled The Florida Dispatch. He edited the
scientific department of the weekly, devoting himself chiefly
to the investigation of injurious insects. Through his interest
in this field, which became very great, he gradually built up a
large collection of insects, and, experiencing great difficulty
in securing determinations, began the study of systematic
entomology. From the very first he was a tremendous worker
and produced results with astonishing rapidity. His contribu-
tions to the scientific journals began in 1879, and from that
date until the time of his final collapse he produced a long series
of contributions to science, comprising more than 250 titles
and including many papers of great systematic value. In 1887
he received an appointment as special field entomologist to the
Division of Entomology of the United States Department of
Agriculture, for the investigation of certain Florida problems.
In 1888 he was appointed entomologist to the State Agri-
cultural College and Experiment Station at Lake City, Fla.,
and while holding that position published one of the very first
bulletins produced by an entomologist of an agricultural experi-
ment station under the Hatch Act. It was entitled " Notes on
Various Injurious Insects." In 1889 he was made an assistant
entomologist and investigator of the Division of Entomology
of the United States Department of Agriculture. During the
winter of 1890-91, on leave of absence, he went abroad and
studied for several months in Berlin. On his return he con-
tinued his work under the Division of Entomology, and in 1895
was appointed assistant curator of the Division of Insects,
United States National Museum, which position he held until
a few months before his death. He donated his large private
collection to the National Museum about 1898.

As a worker Doctor Ashmead was possessed of an enthu-
siasm and an industry that has rarely been equaled. For many
years he allowed himself but five hours, or a little more, sleep,
devoting the remainder of his time, with the exception of that
needed for eating, to an incessant study of the forms in which
he was for the time interested. The amount of work accom-
plished was thus enormous. Either of his two main works,

128 ENTOMOLOGICAL SOCIETY

namely, his Monograph of the North America Proctotrypidse,
published as Bulletin 45 of the United States National
Museum, a work covering some 500 pages, or his Classification
of the Chalcid Flies or the Superfamily Chalcidoidea, published
by the Carnegie Museum, Serial No. 21, a quarto volume of
335 Pages> would have been enough to have monopolized the
working part of the lifetime of any one ordinary man. But
aside from these he left some manuscript for a great mono-
graph of the Braconidse.

Doctor Ashmead was given the degree of Master of Science
by the Florida State Agricultural College, and in 1904 was
made a Doctor of Philosophy by the Western University of
Pennsylvania, the Monograph of the Chalcidoidea just men-
tioned having been submitted as his thesis. He was prominent
in scientific circles. He was an honorary member of the Ento-
mological Society of America, a fellow of the American Asso-
ciation for the Advancement of Science, and a corresponding
member of the American Entomological Society, of Philadel-
phia. He had been president of the Entomological Society of
Washington (1894-5), vice-president of the Biological Society
of Washington, president of the Cambridge Entomological
Society (1894), vice-president of the Washington Academy of
Sciences (1888, 1893, 1894), honorary member of the Ento-
mological Society of Ontario, and vice-president of the Asso-
ciation of Economic Entomologists (1892). He was a member
of the Cosmos Club, of Washington, and of its very important
committee on admissions. He married, in Philadelphia, in
1878, Harriet, the daughter of Thomas O. Holmes. He leaves
a widow and one married daughter.

When he came to Washington, he was a man of large prop-
erty, which, however, was greatly reduced by the disastrous
Jacksonville fire. This, however, did not appear to prey upon
his mind, and he remained, until the end, the same cheerful,
tireless worker in the field of pure science.

Doctor Ashmead's entomological career may be considered
under six headings: His early, mostly economic, work; his
interest in Hemiptera and Coleoptera; the articles on the
Cynipidse ; the descriptive papers on various groups of Hymen-

optera; the monograph of the Proctotrypidse, and the classifica-
tion of the superfamilies of Hymenoptera. His economic work
is best exemplified in his " Orange Insects," in which he was a
pioneer. In the Hemiptera he took great interest, much more
than that indicated by the few papers thereon. He not only
collected Hemiptera extensively, but exchanged with Europe-
ans, amassed a considerable library, and had a manuscript
catalogue to most of the groups. Even to within a few years
of his death he had expected to again devote time to the
Hemiptera. His interest in Coleoptera was chiefly with the
Coccinellidae, in which family he had described a new species
during his economic work.

His work on Hymenoptera began with the study of galls.
He collected them in Florida, a then unworked region, and
described many new species. In rearing the Cynipidse he also
obtained many chalcidids. He thus became interested in all
the micro-Hymenoptera, and these thereafter held first place
in his studies. He described hundreds of new species in this
new field, and after coming to Washington described in other
families, always showing a partiality for the parasitic forms.
Then followed his most valuable and finished work, the Mono-
graph of the Proctotrypidse. To this he devoted several years
of close study, not only, as before, going into specific descrip-
tion, but into the generic characters, and into the general
structure and morphology of the family. The completion of
this great monograph gave him confidence in his powers of
classification ; a confidence that, overlooking all obstacles,
pictured the finished work. Here in the Monograph of the
Proctotrypidse, for the first time, he had numerous illustrations
of the insects, and thereafter in nearly all of his descriptive
papers he endeavored to figure some of the forms.

His success in presenting the generic classification of the
Proctotrypidse doubtless led him to attempt the same for the
other families. This last, and in many ways the most import-
ant work of his career, was scarcely finished at his death. The
magnitude of this task never daunted him, the difficulties in
obtaining literature and specimens never wearied him, but
with the enthusiasm gained from the discovery of new struc-

130 ENTOMOLOGICAL SOCIETY

tural characters he carried the generic classification of all of
the superfamilies, excepting that of the ants, to completion.
Perhaps the most striking one of the series is that on the
Cynipoidea ; but the one which made the greatest stir, was that
on the Ichneumonoidea. The hundreds of genera of this
group, scattered in a most discouraging way through all sorts
of journals, the despair of the systematist, were now available
to all in synoptic form. European Hymenopterists began to
describe new genera and species from all parts of the world.
To this paper was appended his synoptic table to all the fami-
lies, 94 in number, that he recognized in the Hymenoptera. The
largest of these classifications, and the one which Doctor Ash-
mead considered the most important, is that on the Chalcid-
oidea. These tiny insects had long been his favorites, and his
arrangement of them will long serve as the basis for their
study. To this paper was added a catalogue of the South
American chalcidids, with descriptions of over 200 new species.

In the progress of these studies he made a number of
important changes in the position of various families. His
adoption of the superfamily idea enabled him to exhibit the
family relationships to better advantage. He subordinated or
abandoned the venational characters, and drew more heavily
upon the structure of the body for main divisions. The fami-
lies of the old " Fossores " were arranged in two superfamilies,
several of them being united with the chrysidids, eumenids,
bethylids (formerly part of the Proctotrypidas), and the ves-
pids to make the superfamily Vespoidea. The other fossorial
families, forming the superfamily Sphegoidea, were shown to
have more affinity with the bees. The Proctotrypoidea were
associated more closely with the Vespoidea than with the other
micro-Hymenoptera, and the Braconidse were united with the
Ichneumonidse to make the superfamily Ichneumonoidea.

These revolutionary changes in the old-time systems have
naturally awakened much discussion, and the undoubted ten-
dency is now to follow Ashmead, at least in most of his views.

As an appendix to his main lines of study we may place his
descriptive work on the Philippine Hymenoptera. This came
in during his work on the classification. He felt that the

OF WASHINGTON. 131

accession of so much interesting material from such a little-
known country needed attention, and he worked over each
sending from these islands as soon as it was received.

Altogether he described about 3,100 new species, and 607
new genera.

All through his systematic work he never lost interest in
the biological side of the subject, and one of his most enter-
taining articles is the summary of the habits of the aculeate
Hymenoptera. "It was always with peculiar pleasure that he
noted where the life-habits of a group supported his structural
divisions.

Few were more interested in our Society than he. Rarely
did he miss a meeting, and when present he always had some-
thing to say. He contributed a great number of papers, and
his ardent and exultant manner in presenting " two new and
remarkable genera " will never be forgotten. The details of
their structure, their relation to other forms, their effect on
the classification, were all explained to his admiring listeners.

Like so many indefatigable workers in science, Doctor Ash-
mead was most helpful to his fellow-workers. His knowledge
and his time were always at the disposal of others, and he was
noted for his attitude of encouragement towards younger in-
vestigators. He had the kindest of hearts, and will always be
gratefully remembered by those who knew him.

THE ENTOMOLOGICAL WRITINGS OF WILLIAM

HARRIS ASHMEAD, WITH AN INDEX TO THE

NEW GENERA DESCRIBED BY HIM.

BY J. C. CRAWFORD.

In the following bibliography, the numbers given to the
papers are, with a very few exceptions, those assigned by
Doctor Ashmead himself, the only changes made being those
necessary to show priority. In the preparation of this bibliog-
raphy the author has had access not only to a set of Doctor

132 ENTOMOLOGICAL SOCIETY

Ashmead's papers, which was almost complete, but also to
the notes kept by Doctor Ashmead. While the list of titles
is complete so far as longer articles are concerned, and those
describing new genera and species, there are still many un-
signed notes on economic entomology published by Doctor
Ashmead while living in Florida, and also many shorter com-
munications and remarks published in the PROCEEDINGS of the
Entomological Society of Washington.

Titles or parts of titles given in brackets are supplied; in
cases where the complete title is supplied it indicates that the
article was not published by Doctor Ashmead, but that it con-
tains descriptions or tables furnished by him.

In the index to the new genera, the earliest publication found
has been cited, irrespective of whether it has been given with
a described species, a manuscript name, or without citing any
type. In some instances it has been very difficult to find the
first reference, since the genera were often published with no
indication that they were new.

The first number after a genus in the index to the new genera
is the number of the paper in which the genus is described, and
the next, the page reference.

All genera belong to the Hymenoptera, except Eurymeloides
and Polydontoscelis, which are Hemiptera.

NOVEMBER 12, 1908.

The 225th regular meeting was held at the Saengerbund
Hall, 314 C street, N. W. President Hopkins presided and
there were present Messrs. Barber, Burgess, Burke, Crawford,
Currie, Davis, Dyar? Ely, Gahan, Heidemann, Hopkins, How-
ard, Knab, Mann, Morgan, Patten, Sanders, Sasscer, Schwarz,
Ulke, and Webb, members, and Messrs, demons, Fox, Ham-
mar, Hyslop, Russell, Smith, Smyth, Strauss, and Wellman,
visitors.

Messrs. J. A. Hyslop and D. K. McMillan were elected active
members of the Society.

— Dr. F. C. Wellman, the well-known explorer of the fauna
and flora of Portuguese West Africa, spoke by invitation on the
general entomological features of that region. It being im-
possible to more than touch upon a few of the many forms in
his notes, he remarked upon a number of typical species,
among them being the following :

Arachnida. The spiders of the district are most interesting.
Remarks were made on the habits of Nephila senegalensis, N.
pilipes, Araneus rufipalpis, Selenops radiatus, Paraplectana
thorntonij Lathrodcctus hasselti, etc. ; also on the Solpugidse
(Solpuga vineta, S. marshaUi, etc.) the latter being erroneously
considered venomous by the indigenous blacks. Among the
scorpions the most prominent are Uroplectes occidentals and
the formidable Parabuthns granulatus, the bite of the former
being not much more severe than a wasp sting, while that of
the latter gives rise to very serious symptoms. The most
striking mite is the big red " velvet bug," Trombidium grandis-
simum, which is evidently protected from the attacks of birds,
etc., by its warning color. Other interesting groups are the
Gamasidae infesting beetles, which mav almost cover the insect.

c? »•

and the Oribatidae found in mosses. Remarks were made on
the value of these latter as illustrating the zoogeographical
areas of the region under discussion. A number of ticks were
discussed. Amblyomma hcbrtcuni causes painful itching in
human beings. Margaropus decoloratus, Rhipiccphalits coria-
ceus, Margaropus annulatus, etc., abound in cattle, horses, and

158 ENTOMOLOGICAL SOCIETY

mules. Ornithodoros moubata transmits both human spiro-
chsetosis and filariasis. Experiments were made looking
towards its extinction. A fungus (allied to Entomophthora),
which kills it, and a bug, Phonergates bicoloripes, which preys
on it, were discovered but could not be employed practically.
Changing men from beds to hammocks with cotton wool sur-
rounding the suspending ropes was successful in a large
measure as a protective device.

Myriapods. Venomous species (Scolopendra morsitans and
lata) were mentioned, also several species of Cormocephalus.
Two genera of large julids (Spirostreptus and Odontopyge)
were discussed at some length.a A curious fact hitherto un-
noted is that at the end of the dry season when the struggle
for existence is very fierce these millipedes excrete an excess
of irritating material from the foramina repugnatoria, which
runs down on the legs, making them poisonous, so that the
track of one, if it crawl over the human skin, leaves a weal
like that made by a red-hot iron.

Insects. Thysanura were first taken up. On one occasion
only, at the end of the rainy season, vast numbers of a small
blue-black podurid were seen almost completely covering the
surface of small ponds. Campodeidse (which run backward
and forward with equal facility) frequent bungalows and are
used by children as playthings. Some of the species of Lepis-
matidse are very large, and some are predaceous, having been
observed to prey on beetle larvae and also on the imagines of
the common wood-borer Bostrichopsis cephalotes, entering the
burrows of these latter and invading the beetle, leaving the
eviscerated exoskeleton to fall to the ground. Among dragon
flies Crocotheniis sanguinolenta, Orthctrum chrysostigma, and
O. caff rum were pointed out as striking and beautiful insects.
The latter species was once seen carrying about a small snail.
Termites have many types of habit. Some serve like earth-
worms in loosening the soil. One species has soldiers which

a During the discussion which followed, Doctor Wellman, in answer
to questions, entered more fully into the distribution, copulation, early
stages, means of defence from enemies, and other habits of these
millipedes.

discharge an irritating fluid from a tube opening on their
heads. Still another lives on top of the ground in bright sun-
light. T. bellicosus is the commonest species and T. fatalis
builds the highest mounds, often 15 feet in height. Their
ravages are enormous. Earwigs are numerous and remark-
able. Some are of large size (Apachya chartacea and A.
reichardi). The most interesting is a gigantic new genus and
species (Sacnodes wellmani) which nips severely with its
pincers, drawing a drop of blood. As it lives in refuse the
wound inflicted often festers badly and the natives have come
to consider it venomous. A large Australian species (Aniso-
labis colossa) has much the same habits and reputation. A
number of species of Orthoptera were mentioned, among them
the giant cricket (Brachytrypus nicmbranaceus), which is used
for food, and the travelling locust (Schist ocerca peregrina).
This latter appears in clouds which darken the sun. It is
often infested by a nematode (Gordius), and is eaten in vast
quantities by a plover-like bird (Glare old nordmanni). Locusts
are employed by the indigenous blacks as an article of diet.
On one occasion the insects were found dying over a large
area but the cause of death could not be ascertained. Bugs
were next taken up. The common bed bug is not lectularius
but a new species. Reduviidse are striking and include several
" kissing bugs," notably Sphcdanolcstes zvellmani. Among
Homoptera there are a number of very large handsome cicadas
belonging chiefly to the genus Platypleura. A number of
Lepidoptera were collected. A singular fact is that a large
moth (Macroglossa trochilioidcs} is usually mistaken by the
colonists for a hummingbird. The larvae of various Lima-
codidse, Arctiidse, and Liparidse have caterpillars with stinging
hairs, causing urticaria when handled. Several very large
saturnids were also mentioned, as well as the habits of the very
common Limnas chrysippns and the gregarious Lampides tcli-
canus, etc. Diptera (including fleas) were next reviewed.
The ovipositing of an ephydrid fly in ants (Cremastogaster)
was mentioned as a striking departure from the usual habits of
the family. The terrible "veldt gnat" (Shnuliitiii ^'cllinani),
the parasitic "floor maggot" (Auchmcrotnyia hiteola}, the

160 ENTOMOLOGICAL SOCIETY

myrmecophilous Runchomyia wellmani, mosquitoes, and tse-tse
flies were all touched upon. Beetles (of which a large collec-
tion was made) came next. The stinging larvae of a mala-
coderon (Drilus) and of an elaterid (Tctralobus} were first
mentioned. Zographus jerox was spoken of as a common
article of food, together with large buprestids. One of these
latter (Psiloptera tnonstruosa} , of very remarkable appear-
ance, was commented upon. The tiger beetles and the blister
beetles were specially discussed in relation to geographical
distribution and general biological conditions in the region.
Numerous species of Hymenoptera were referred to. Formi-
dable social wasps (Belonogaster guerini, Polistes fastidiosus,
etc.) and some large species of Scolia, Salius, etc., were de-
scribed. Many bees, a majority of them new, were collected.
The existence of mites (Paragrcenia) in an abdominal pouch
of a carpenter bee was reported. The address closed with
some notes on the habits of certain ants, Camponotus zvell-
mani, Pheidole punctulata, Polyrhachis militaris, and Palto-
thyreus tarsatus.

— Doctor Howard introduced Dr. F. B. Smith, Director of the
Transvaal Department of Agriculture. Doctor Smith told of
the great debt that the other countries owe to the United States
for the progress in economic entomology, and also spoke of
the excellent work of the late Mr. C. B. Simpson, a former
member of this Society, who started the entomological work
of the Transvaal Department of Agriculture and the Inter-
Colonial Locust Bureau of South Africa.

-Mr. Charles R. Ely presented the following paper and
exhibited specimens of the adults of the species treated and of
some closely related species :

DESCRIPTIONS OF TWO NEW SPECIES OF

ACROBASIS.

[Lepidoptera, Pyralidse.]

BY CHARLES R. ELY.

Among some specimens of the genus Acrobasis taken by the
writer at East River, Conn., were a few which are pronounced

OF WASHINGTON. 161

by Dr. H. G. Dyar to belong to two species hitherto unde-
scribed. Doctor Dyar has kindly allowed me the privilege of
describing and naming them.

v Acrobasis sylviella, n. sp.

Head and thorax ash-gray; abdomen gray, the segments ringed with
yellow-gray. Fore wings ash-gray, with smoky shadings ; the scale
ridge very dark, broad and short ; outer line dark, very distinct, accent-
uated by an outer pale-gray shade; beyond this a dark band followed
by a lighter shade; a marginal row of dark dots; fringes pale; discal
dots separate in two specimens, joined in one specimen. In the male
there is, on the under side, a very short, black costal streak near the
base of the fore wings and a notch on the costal margin near the base.
Hind wings yellow-gray, with smoky tinge, dark near margin.

Expanse 19 to 20.5 mm.

Two males and one female, East River, Conn., July 19 and
22, 1908 (Chas. R. Ely).

Type. — No. 12115, U. S. National Museum.

S Acrobasis irrubriella, n. sp.

This species is quite close to Acrobasis latifasciella Dyar,a from which
it may be distinguished by the following points of difference : Head
and thorax not so reddish ; band beyond the scale ridge narrower, only
slightly marked with orange-red ; outer line only slightly mesially ex-
serted, not so distinctly denticulate, not followed by an orange-red shade.

Expanse 18.5-19.5 mm.

Two males and one female, East River, Conn., July 8, 20,
and 24, 1908 (Chas. R. Ely).

Type. — No. 12116, U. S. National Museum.

-Doctor Howard exhibited drawings of the antennae of
Tyndarichus and Schediiis, new genera of the family En-
cyrtinse, and stated that these insects are egg parasites of the
gipsy moth in Japan and apparently very important. He said
that it is rather remarkable that two such closely related
species should be parasitic on the same host in the same
locality.

— Doctor Howard also exhibited a drawing of Atoposomoi-
dea, a new genus of Elachertinae, and stated that while from

a Notes on the species of Acrobasis, with descriptions of new ones,

162 ENTOMOLOGICAL SOCIETY

its relationships it would be expected to be a parasite of some
tineid. leaf miner, it was reared from the cocoons of Glypta-
panteles.

— Mr. Webb exhibited an old wagon spoke which showed
the work of the longicorn beetle Chion cinctus Drury. He
stated that the evidence strongly indicated that the beetle had
lived in the spoke for eight or ten years as a larva. It then
changed to an adult, which was still living when received.

Mr. Schwarz called attention to the fact that the subject of
retarded development had been thoroughly discussed by the
Society at a previous meeting and that this discussion is
recorded on pages 108-127 of Volume III of the PROCEEDINGS.

— Doctor Dyar presented a paper entitled "The Larva of
Lerina incarnata Walk." It is as follows :

THE LARVA OF LERINA INCARNATA WALK.

[Lepidoptera, Lithosiidse.]

BY HARRISON G. DYAR.

Larva. Head rounded, wider than high, truncate below, f nil ; clypeus
moderate, pale reddish, shining, the sutures of the mouth and ocelli
darker. Body cylindrical, robust, whitish luteous, covered by the hairs,
unmarked. Warts large, but low and flat, black, distinct, i to vi normal,
iv rather large ; on the thorax 2 warts above the stigmatal wart, large,
distinct, separate ; wart iii a small wart situated behind wart iv + v.
Hair uniform, short, abundant, foxy reddish, evenly cut. Thoracic
feet black, the abdominal ones with large black hairy plates, the inner
sides of the legs also hairy. No cervical shield nor anal plate.

Food plant: " Milk weed," Asclcpias pumila (A. Gray) Vail.
Larvae collected by Mr. Morris Chrisman, Huachuca Moun-
tains, Arizona, and handed to me by Dr. A. D. Hopkins.
The larva has the structure of an arctian, not a lithosian.

— Mr. Schwarz recorded the discovery on the North Ameri-
can continent of the coleopterous parasite of the common
cockroach (Blattella gcrmanica L.), namely, the genus Rhipi-
dius. Last year one dead male specimen was found by Mr.
Frederick Knab on board of a steamer plying between San

OF WASHINGTON. 163

Francisco and Central American ports, and in September of
this year Dr. S. Austin Davis sent to Doctor Howard a female
specimen which was found on board of one of the Panama
Railroad steamers which ply between New York and Panama.
Mr. Schwarz reviewed the history of this genus and said that
he has come to the conclusion that the species is nothing else
than the old Rhipidius pectinicornis Thunb. From the fact
that the female has well developed legs and is provided with
eyes and normal antennae he concluded that the female leaves
the body of the roach and crawls about as any ordinary beetle.

— Mr. Sanders exhibited photographs of adults and larvae
of the scale Lophococcus mirabilis Ckll., which were received
from the northern Transvaal. They live on the acacia, the
thorns of which the adults mimic. The larvae resemble the
winged seeds of some plants, but are not believed to be mimics.

— The Secretary read notes from Messrs. E. O. G. Kelly
and T. D. Urbahns on some experiments with Lysiphlebus
tritici Ashm., the hymenopterous parasite of the spring grain-
aphis or so-called " green bug " (To.voptera graminum Rond.).
The breedings and rearings of this insect show that the species
will parasitize not only Toxoptera graminum but also various
other aphides — Aphis setaricc, the cotton or melon aphis (A.
gossypii Glov.), the corn root-aphis (A. maidi-radicis Forbes),
the corn leaf-aphis (A. maidis Fitch), and the cabbage aphis
(A. brassier L.). The experiments, in detail, are as follows:
(i) Specimens of Lysiphlebus, reared from To.voptera, para-
sitized A. setaricc, their offspring (or the second generation)
parasitized To.voptera, and the third generation parasitized
A. setaricc, from which the adults developed. (2) Lysiphlebus,
reared from To.voptera, parasitized A. setaricc, their offspring
parasitized A. maidis, and from the latter the adults emerged,
(3) Lysiphlebus, reared from Toxoptera, parasitized A. maidi-
radicis ( ?) on Erigeron canadcnse, their offspring parasitized
To.voptera, and from the latter the adults developed. (4)
Lysiphlebus, reared from To.voptera, parasitized A. gossypii
on primrose and from these the adults developed. (5)
Lysiphlebus, reared from A. setaricc, parasitized To.voptera,
their offspring parasitized A. maidi-radicis ( ?) on Erigeron,

164 ENTOMOLOGICAL SOCIETY

and the adults from the latter parasitized Toxoptera, from
which the adults emerged. (6) Lysiphlebus from A. setaria
parasitized A. maidls, from which the adults were secured.
(7) Lysiphlebus from A. brassicce parasitized Toxoptera, from
which the adults were secured. (8) Lysiphlebus from A.
gossypii on cotton, sent by Mr. C. N. Ainslie from Mesilla
Park, N. Mex., parasitized Toxoptera and from the latter
the adults emerged.

— The Secretary read also a note from Messrs. Kelly and
Urbahns describing experiments showing parthenogenesis in
Lysiphlebus tritici Ashm. Starting with a virgin female
Lysiphlebus (the offspring of a fertilized female), issuing
from a parasitized Toxoptera that had been placed in a vial,
101 of the offspring were males and 6 were females, each issu-
ing in a separate vial. Four of these females were allowed to
parasitize Toxoptera, and their offspring were all males.
Starting with a supposedly fertilized female, a virgin female
offspring was isolated; the offspring of this latter female
comprised 69 males and 3 females, and the offspring of one of
these 3 virgin females were 5 males and 2 females. One of
the last-mentioned females, unfertilized and parasitizing
Toxoptera, produced 51 males, while the other produced 15
males. In numerous cases no females were produced, in one
instance the offspring of a single virgin female being 186 males.

— Mr. Schwarz said that a species of Spirobolus, a millipede,
has transformed a thick layer of fallen leaves into a granular
mass of excrement which covers the ground between the rocks
along the upper Potomac River to a considerable depth. In
some localities there is practically no soil except this layer of
excrement.

— The following papers were presented for publication :

BRASSOLIS ISTHMIA, A LEPIDOPTEROUS INSECT

HIGHLY INJURIOUS TO COCOANUT CULTURE

IN THE PANAMA CANAL ZONE.

BY HENRY F. SCHULTZ.

Early in May, 1906, on my arrival on the Isthmus, I found
the majority of the cocoanut trees in this neighborhood de-

OF WASHINGTON. 165

foliated by the attacks of a caterpillar. Large trees which had
been bearing crops for a number of years stood without a
particle of foliage, their bare petioles and midribs resembling
skeletons and with none of the ragged picturesqueness charac-
teristic of this species. Some of the trees were in hopeless
condition and had to be cut down, but the rest recovered
under special care given them.

Later in the same year, about the middle of September, the
caterpillars again appeared, although not in the same large
numbers as before, and began to strip the trees anew. All
cocoanut trees were, therefore, sprayed with a weak solution
of arsenate of lead, a most tedious and troublesome, although
very effective, method of combating these insects, in view of
the great height of the trees, most of which measured from 30
to 35 feet. This time some of the royal palms were also, but
not very badly, affected, and in their case spraying was out of
the question, their still greater height making it impossible to
reach them by ladders ; and " royals," particularly the Oreo-
do.va oleracea, have too thick a trunk to allow even the natives
to climb them.

Although the torrential rains washed off the arsenate of
lead after a few weeks, it stayed on long enough to kill all the
insects on the trees which had received treatment, but a num-
ber evidently reached maturity on the royal palms and de-
posited their eggs in turn on the cocoanut trees.

This year ( 1907) the caterpillars made their first appear-
ance in May, during my absence from Ancon through vaca-
tion, and I found a number of trees sporadically infested with
them on my return. I suppose this was the time when the
mature insects deposited their eggs freely on all cocoanut trees
in this vicinity, for about the latter part of August thousands
of their larvae began to defoliate these palms again, evidently
determined not to leave a single leaf on the trees.

One thing in their favor is the circumstance that the larvae
feed only at night and that they retire before the first sun-rays
into a tough web spun with pinnae of the leaves, where fre-
quently as many as 700 to 800 of them crowd together into one
" nest." The lower part of this, where the ends of the pinnae
meet, is left slightly open, probably through instinct of the
caterpillars, to allow for the escape of their dung, and the
whole presents the appearance of a long narrow bag, from 30 to
60 centimeters in length, according to the number of insects it
contains. Frequently a tree will have two, three, and even four
of these " nests " and some were found with an estimated
number of over two thousand full-grown larvae. What even

166 ENTOMOLOGICAL SOCIETY

half of this number can do to a full-grown tree, if their ravages
are not speedily intercepted, can be imagined, especially if the
fact is kept in mind that they attain the respectable size of 5 to
10 centimeters in length, and that their appetite, like that of
most other caterpillars, is altogether monstrous.

A bearing cocoanut tree will thus be stripped of every inch
of foliage in a few nights and receive such a severe check in
its growth that, even with all due care in preventing the re-
appearance of the pest in the following years, at least two or
three crops will be lost. It is no rare occurrence, however,
that a tree will die outright, or become so weak that it can not
resist fungous and other diseases, and will gradually perish.

After reaching maturity, or when the supply of food gives
out, the larva passes into the chrysalis stage, in which it re-
mains 12 to 1 6 days, and this is the time when the larva of an
apparently dipterous insect helps in the destruction of the
Brassolis.

I have not been able to find out whether the mature parasite
deposits its eggs cutaneously into the caterpillar, or into the
chrysalis, or whether its ova are introduced into the alimentary
tract of the larva with its food, as I have found the parasite
larva only in the chrysalides. Doctor Darling, Chief of the
Board of Health Laboratory at Ancon, had examined almost
mature larvae of the Brassolis under a high-power microscope
without finding any traces of parasite ova in either the skin or
intestinal ducts. However, as only a small number of them
could be thus examined, on account of lack of time, it is possi-
ble that the few specimens under observation were not para-
sitized. As the parasite larvae are not protected with a skin
which, in my judgment, would be tough enough to withstand
the gastric juices of their host, the probability of a cutaneous
infestation suggests itself.

The destruction of the Brassolis through its parasite seems
to be rapid, although the actual time required can not be given,
as those in captivity appeared to be free from infestation.

From the microscopic examination of the contents of three
diseased and dead chrysalides by Doctor Darling, the following
points were learned: The contents were fluid and granular,
and a fresh smear showed many fat droplets, discrete and in
round aggregations (mulberry-like). The tracheal tubes were
found in some brown debris, but no parasite ova, bacteria,
or micro-organisms of any kind could be detected. With the
polarizing microscope the fat droplets did not show crosses.

The fat droplets take the stain well with Sudan III. Stained
with polychrome methylene blue, there are numerous eosin

OF WASHINGTON. 167

stained disks resembling red blood corpuscles, about 3 microns
in diameter, many large fat globules, a few mononuclear cells,
and no micro-organisms; otherwise negative.

As above stated, the larvae feed only at night and try to hide
in their " nests " during the day, but this " hiding " becomes in
reality the means by which they are most easily detected and
destroyed, for it is much easier to cut down these " nests "
than to spray the trees ; nevertheless, it requires constant vigi-
lance on the part of the grower. Where the trees stand
isolated, as here on the hospital grounds, the insects are more
easily controlled than in a grove where the trees frequently
touch one another and where the caterpillars can crawl from
tree to tree. Altogether, the Brassolis will turn out to be a
most formidable enemy for the cocoanut grower if it is allowed
to spread, and every possible attention should be given to the
immediate destruction of the larvae at their first apparance.
I will add that I have noticed Brassolis isthmia on the follow-
ing wild and cultivated palms of the Isthmus, besides cocoanut :
Martinesia caryotccfolia, Acrocomia sclerocarpa, Oreodoxa
regia and oleracea, and two unidentified species of Thrinax.

I have recently received, through !Prof. R. H. Forbes, a
species of Eriococcus collected by Mr. D. J. Craig at Bellevue,
Gila Co., Ariz., on Quercus toumeyi Sargent, occurring on the
small twigs in company with a species of Eulecanium. Upon
examination it proves to be one of the species or races of the
E. quercus group, distinctly differing both from true quercus
and from toumeyi Ckll., the latter being from Arizona, on
Prosopis. It may be described as follows :

Eriococcus quercus gilensis, n. subsp.

Ovisac pure white, ordinary, about 4 mm- long. On boiling in caustic
potash the insect does not stain the liquid pink. Dermal spines strong,
about 45 A* long. Tibia always longer than tarsus. Antennae 7-jointed,
joint 4 always longest, longer than 3, which averages a little longer
than 7; 5 and 6 short and equal.

The following measurements are in M. Femur and trochanter : Middle,
190; hind, 205. Tibia: Anterior, 125; middle, 145; hind, 150. Tarsus
(without claw): Anterior, 67; middle, 75; hind, 82. Antennal joints,
different examples: (2) 37^, 30, 30; (3) 42^/2, 42^/2, 37l/2, 35 J (4) 57^2,

A NEW BRACONID OF THE GENUS ELASMOSOMA.

BY T. D. A. COCKERELL.

On the afternoon of July 16, 1908, at Boulder, Colo., my
wife called me to see a great battle between the ants Formica
sanguined Latr. and F. snbpolita Mayr. which was taking
place on the pavement adjacent to the university campus. As
we watched the conflict, my wife noticed certain minute insects
hovering over the ants. They remained hovering in the air
about an inch above the ground, darting downwards at inter-
vals to alight for an instant on the back of a worker F. sub-
polita. Two specimens were collected, and, as was expected,
they proved to belong to the curious genus Elasmosoma*

Elasmosoma vigilans, n. sp.

Female. Length, 2 mm. or slightly more ; black with a dullish surface,
the abdomen more shining ; abdomen a little shorter than thorax ; wings
hyaline, the costa and stigma dark brown; legs very pale reddish, the
tarsi white, black at apex; antennae dark, 12-jointed, the flagellar joints
with numerous longitudinal keels, and with many short pale hairs ; broad
apical margin of clypeus, labrum, and mandibles very pale yellowish,
the apices of the mandibles ferruginous ; mandibles strongly bidentate,
the inner tooth about half as long as the outer; face and front
with fine transverse lineolation, passing into reticulation; mesothorax
with very fine punctures of two sizes, and scattered short pale hairs ;
scutellum similarly sculptured; sides of metathorax with coarse irreg-
ular reticulation; abdomen with very fine and very dense punctures,
its lateral margin sharp; basal part of marginal neurone brown and
distinct, but it ends before level of end of stigma in a swelling, and
beyond that is merely indicated by a faint shade. The middle and
hind coxae are pale, concolorous with their trochanters and femora.

The short abdomen alone will readily separate this from E. schivarzi
Ashm. and E. pergandei Ashm. ; from E. bakcri Ashm. (from Fort
Collins, Colorado) the color of the middle and hind coxae would serve
as a mark of distinction, but as E. bakcri is only known in the male, it
occurred to me that the present insect might be its female. Mr. J. C.
Crawford has very kindly compared one of my specimens (now in the
U. S. National Museum) with the type of E. bakcri, and is of the
opinion that it is distinct. In E. bakcri the region in front of the

ocelli is merely transversely striate, whereas in E. vigilans it is punc-
tured, the punctures running in rows between the striae, or, more prop-
erly, raised lines.

Boulder, Colo., evidently parasitic on Formica subpolita.

A NEW GALL-MAKING COCCID ON ATRIPLEX.

BY T. D. A. COCKERELL AND S. A. ROHWER.

In October, 1896, in the outskirts of Las Cruces, New
Mexico, Prof. C. H. T. Townsend found a bush of Atriplex
canescens on which were many small leaf-galls. The senior
author studied these at the time, and later collected additional
material, but was not able to come to a definite decision as to
the gall-maker. The galls all contained remains, more or less
imperfect, of what appeared to be an Eriococcus, but the
material was somewhat old, and had been very much injured
by both chalcidid and dipterous parasites. Moreover, the
locality was exactly the type-locality of Eriococcus neglectus
Ckll., and it seemed possible that we had to do merely with
some E. neglectus which had crawled into galls otherwise made.

This unsatisfactory conclusion could not be modified until
this year, when Mr. L. C. Bragg rediscovered the galls on
Atriplex canescens at Trinidad, Colo. Mr. Bragg has sent us
good material, and there appears to be no doubt that we have
to do with a distinct and undescribed gall-making coccid.

ATRIPLICIA, n. gen.

Female gall-making; having the general structure of Eriococcus,
but with only bristles, the spines of Eriococcus absent. Antennae
7-jointed, formed as in Eriococcus, the last joint not the longest; caudal
tubercles long and cylindrical ; anal ring with 8 hairs ; legs well devel-
oped, the tarsus (excluding claw) a little longer than tibia.

Atriplicia gallicola, n. sp.

Oval, about 1.5 mm. long, reddish pink when fresh, turning dull
crimson when boiled in caustic potash ; not enclosed in an ovisac. Skin
with scattered bristles, not numerous. Antennae and legs red-brown, of
ordinary form, the claws long. Caudal tubercles cylindrical, about
30 M long and 20 M broad at base, emitting a long bristle (about 105 M).
Antennae 7-jointed, the joints measuring in p (i) 20-25, (2) 22-25,
(3) 33, (4) 28, (5) 18, (6) 15, (7) 28. The tibiae are about 77 (an-
terior leg) to 100 (hind leg) M long, the tarsi 80 to 105 M.

170 ENTOMOLOGICAL SOCIETY

The gall, about 4.5 mm. long, consists of the subglobular swollen
base of the Atriplex leaf, the sides being folded upwards, leaving an
open slit above, the margins of which are curled outward. The end
of the leaf makes a pointed process at the end of each gall.

Las Cruces, N. Mex. (Townsend and Cockerell) ; Trinidad,
Colo. (L. C. Bragg). Trinidad is the type locality.

Mr. Bragg also reports that he found Kermes gillettei at
Trinidad.

PARASITE.

A very interesting parasite has been reared from this insect,
which seems to possess characters common to the Encyrtinas
and Aphelininse. The material is not in condition for descrip-
tion, but this statement is made in the hope that some future
observer, finding Atriplicia, will try to rear a good series of
the parasite.

THREE NEW TICKS FROM THE UNITED STATES.

BY NATHAN BANKS.

In describing Dertnacentor venustus in my Revision of the
Ixodoidea, or Ticks, of the United States,a I had a few speci-
mens that would hardly fit and were left unnamed, or placed
doubtfully with that species. Several males, in the collection
of the Department of Agriculture, were from Prescott, Wash-
ington, taken from a horse in February, 1896. Since the pub-
lication of the Revision I have received several ticks from Dr.
H. T. Ricketts, who is interested in the spotted fever, and
among the material were two females and a male from a horse
at Mountain Home, Idaho. These agree with the specimens
from horse at Prescott and differ from D. venustus in several
ways, so that I shall describe it as follows :

Dermacentor modestus, n. sp.

Male. Red-brown, marked with white lines and dots, but not so
heavily as in D. venustus or D. occidentalis; the heaviest marking out-
lines the region of the shield of the female; legs slightly marked with
white. Capitulum scarcely as broad as that of D. venustus, the hind
angles hardly as much produced; dorsum hardly as much widened
behind as that of D. venustus, punctulate as in the allied forms; hind
coxae about twice as wide as long on base, armed as usual.

Length, male, 3.5 mm.

a Technical Series, No. 15, Bureau of Entomology, U. S. Department
of Agriculture, 1908.

OF WASHINGTON.

171

Female. Capitulum and legs reddish brown; shield mostly white on
sides and behind, leaving much of the middle area unmarked, abdomen
dark brown. Capitulum broad, rather broader than in D. vcnuslus,
with smaller porose areas, distinctly separate, and less pear-shaped;
shield of the general shape of D. vennstus, a little more narrow, fully
as long as broad, coarsely punctate on sides, much more minutely in
middle and behind.

Length of female shield, 1.5 mm.

Specimens from Mountain Home, Idaho ; Prescott, and
Olympia, Washington.

Close to D. venustus, but in the male the stigmal plate (fig.
12, upper figure) has the projection pointing more backward,
and in the female (fig. 12, lower figure) the projection is more
obliquely upturned. Smaller than D. venustus, and with less
white, especially noticeable in the male.

Another new tick adds a genus to our fauna ; it is the fol-
lowing :

Aponomma inornata, n. sp.

Dark mahogany-brown, unmarked ; legs paler reddish brown. Body
about one and two-thirds as long as broad, as broad behind as in front,
surface minutely striate and more coarsely wrinkled; three deep longi-

tudinal furrows on posterior part of the dorsum, limited by a sub-
marginal furrow; the festoons distinct. Shield (fig. 13) as broad as
long, deeply emarginate in front, densely and deeply pitted, especially
on the middle area, lateral carinse distinct, curved; no trace of eye-like
spot. Capitulum (fig. 14) subtriangular, the porose areas rather elon-
gate, separated by a narrow space. Legs of moderate length ; coxae
all small, coxa I with two subcqual spines behind, others unarmed ;
tarsus I one and one-third longer than the preceding joint, in other

tarsi (see fig. 15) the basal part much shorter than the apical part, all
tarsi tapering to the tip. Palpi slender, middle joint about twice as
long as the apical joint. Stigmal plate (fig. 13) elongate, with a short,
broad, dorsal prolongation, surface nearly smooth.
Length of female, 8 mm.; of shield, 1.5 mm.

Taken from a dog at Corpus Christi, Texas (Hooker) ; also
from rabbit at Victoria, Texas (Mitchell).

The third species, described below, is an Ixodes related to
L hexagonus.

Ixodes texanus, n. sp.

Hard parts red-brown ; shield rather yellowish in middle, legs
paler reddish brown, rest of body lead-brown to black. Shield
(fig. 1 6, at left) a little longer than broad, anterior sides rounded,
posterior sides slightly concave, finely punctate, above the lateral parts

striate, no distinct lateral carinse. Capitulum (fig. 17, at right)
trapezoidal, strongly wrinkled above; porose areas nearly circular, well
separated. Palpi short and broad. Abdomen, in engorged female,
much elongate and posteriorly swollen. Legs short, tarsus I one and
one-fourth times as long as preceding joint; all tarsi end abruptly, the
joint being slightly swollen above before tip; coxa I (fig. 17, at left.

above) with a very short process, hardly a spine. Stigmal plate (fig. 17,
at left, below) subcircular, quite strongly sculptured.
Length 6.5 mm. (swollen female) ; shield, I mm.

From a raccoon in Live Oak County, Texas (Mitchell and
Bishopp).

This species will run to I. hexagonus in my table of Ixodes
in the Revision of Ixodoidea, but it differs at once from that
species in the abruptly-ending tarsi, as well as in minor points,
as shape of porose areas, etc.

A CATALOGUE OF AMERICAN AQUATIC AND SEMI-
AQUATIC HEMIPTERA.

BY G. W. KIRKALDY, F.E.S., and J. R. DE LA TORRE BUENO.

As no catalogue of aquatic Hemiptera has been published
for more than thirty years, the present list has been prepared
for the use of our colleagues and ourselves. It was our inten-
tion at first to restrict it to the species of America north of
Mexico, but the American regions and subregions are difficult
to limit sharply, and so many northern workers visit the An-
tilles, Mexico, and even farther south, that we feel that a more
comprehensive list will be at once scientific and convenient.

A large amount of material is in our hands for working up,
and in due time we hope to replace this list by a critical synop-
sis of the American aquatic and semiaquatic Hemiptera.

In this list the references have been abridged so that they
may be given complete for each genus and species. The genus
under which each species has been described is given in paren-
theses following the name of the species. The numbers of
the families, subfamilies, and genera are those in the senior
author's List of Genera,* such as are omitted being those that
do not occur in our fauna. This catalogue is intended to in-
clude everything published before July I, 1908.

The following works at least should be in the possession of
every worker in aquatic forms in the Heteroptera :

a In this genus all the species have been revived, as it is nearly
certain that, being described by color characters only, many species
have been confused, and until a revision of the genus is made it will
not be possible to be absolutely sure of any synonymy in the group.

b The species is stated by various authors to be found in the follow-
ing places, but the localities appear doubtful, at best, to the authors:
Texas; Mexico; Guatemala; Honduras; Nicaragua; Costa Rica; Pan-
ama. Uhler also cites Lower California, but he is manifestly in error,
as the insect from the West Coast is absolutely different from that
from the type locality, Carolina. Brazil and Bolivia are also cited, but
not accepted by us.

a Here again we have a distribution too extensive and too scattered
to be real. The specie^ of the genus are so similar in coloration that
the description of one can apply to several. Consequently, any other
localities than those north of Mexico and on the Atlantic seaboard
should be regarded as open to question, at least for the present.
