for the Lymantriidac: three above the stiff- matal wart on joints 3 and 4; wart i tnod- erately large on abdomen: wart i+ very
small, behind the spiracle; leg plates dis- tinct. Dorsal eversible areas on joints 10 and n normal, whitish, more or less con- cealed by the hair, often completely so. Body black with a frosty gray shade; hair thick, all lmrbuled, some heavily feathered but none plumed. Tufts from warts i on
joints 5 to 9 and 12 a little more closely bunched, but no true tufts and no pencils. Hair gray, mixed with black, with bright yel- low hairs on the lower side of wart ii on joints 5 to 13 and.at the bases of all the hair bunches on the thorax. Siihventral hair
bunches small. The gray hairs are densely feathery on warts i to v, the black and yel- low ones only spinulose. Hair not very
long, quite even but not regularly so.
NOTES ON THE SPECIES OF EXORISTA 0V TEMPERATE NORTH AMERICA.
å´B C. 11. TYLER TOWNSEND, LAS CRUCES, N. MEX. The following twelve speciesof Exo-
rista all belong to the middle ii~~d
eastern United States with one excep-
tion, E. Zag-ode being from Guanajuato
on the Mexican tableland. They com-
prise all the species that I have so tar been able to recognize from the tein-
perate portions of North America.
None of the twenty-seven Mexican
species described by Mr. v, 11. Wulp
.are included. They mostly belong to
the neotropical fauna. I am under
many obligations to Mr. S. 11. Scudder
for sending me, some years ago, the
types of the dipterous parasites men-
tio'ned in his Butterflies or the Eastern United States and Canada. It was a
study of these, and comparison of them
with other types which I then possessed, that enabled me to prepare the follow-
ing table of Bxorlsla, as well as a
similar one of the allied genera Alasi-
cera and rhorocera. I have ex:iinined
all the species mentioned in the table.

Exofista nigripalpis, n. sp.- With median and miu'ginal macrocliaetae, but not other- wise bristly, thus differing from hir,wta. The abdomen is also more rounded, shining black, approaching that of theclarutn.
Palpi
black. Eyes not thickly hairy. Differs
from theclarum chiefly in possessing discal bristles on thc abdominal segments. It is intermediate between theclarti71z and /;/;x;tn. Size about the same, 5 or 6 mm. From
Illinois ( ?). Type in University of Kansas collection.
The temperate American species of
Exorista which I have not jet been
able to examine are : E. leucaniae
Kirkp., cecrofiiae Riley, doryphorae
Riley, deilephilae 0. S., and infesta
Will. The others mentioned in the
Ostcn Sackc11 Catalogue (ire Walker's
species, and none of them has been
recognized. -å£'.flavicaud Riley is a
Frontina. JK. ckrysophani Towns is
a synonym of fheclar'am. IC J?. dei-
lephilqe has the hind tibiae neither
ciliate nor sub-ciliate, it will fall with å´platysamia in the table, and may be
distinguisl~ed at once from that species by the sides of the
abdomen being"
broadly red. 23. poserpina Will.,

sidered as a possible variety of blanda, may or may not be a good species .or
even variety.
The 9 specimen described by me on
page 364, Trans. Am. Ent. Soc., 1891,
I am inclined to regard as the same
species, ciliata, to which I there doubt- fully referred it. It would certainly
seem at first that the differences de-
scribed were specific. but still greater

NOTES ON SMERINTHUS CERYSII KIRBY.
BY F. L. HARVEY, OKONO, ME.
In his Monograph of the Sphingidae,
p. 222, Prof. J. B. Smith says the early stages of the above species are entirely unknown. We are not aware that any-
thing has since been published and
presume the following notes may prove
interesting.
On May 13, 1895, we received a
pair of S. ceyii froin Mr. Albion
Townes, VVinthrop, Me. They were
mating when captured and remained
together for two hours. The next
morning there were several eggs in the
box. The female continued to lay eggs
until May 17, making the period of
ovulation about five days. The num-
ber of eggs laid was about 160. The
eggs began to hatch about May 27 and
continued to emerge for about five days
making the egg period 15 days.
Mr. Ora W. Knight, who had the
care of most of the larvae and succeeded in carrying some through all of the
changcs, made the following notes:
" Placed the larvae in a gauze net
upon Sulix sericca Marshall. They
were fed in this way until June 25,
when 1 was obliged to take them home
and they were afterwards fed upon
leaves. They did not thrive
so well and many died, not having
strength to pupate. Seven entered
the pupa state about July 13. Of
these only five emerged, and they
unusually small. The great mortality
may have been in part due to insuffi-
cient food- but this species seems to be very tender, which accounts for its
scarcity in nature.".
Prof. Carl Braun secured a female
on willow in his garden, Bangor, Me.,
which laid nearly 200 eggs, and sue-
ceccled in getting about 50 pupae from
which only one male and one female
emerged. His specimens were fed
while young upon willow and after the
last molt upon poplar.
Mr. Knight has found the larvae of
this species feeding upon Balm of
Gilead. The larvae are subjected to
the depredations of parasites.
The following description of the
eggs and larvae were made by the
writer.
&as pale green, oblate spheroid, much
flattened, 2 mm. long.
L m n c just hatched, 4 mm. long.
Apple
green, horn pale green, when hatched, but turning black inside of two hours. First molt on the seventh day, when the horn
became lighter colored. The other molts
we did not observe.
- Mature larvae apple green, about 38 mm. long, covered with minute granulations.
Yellow stripe on each side of head. Seven oblique pale yellow stripes on each side of the body. The posterior wider and brighter,
