NOTES ON SMERINTHUS CERYSII KIRBY.
BY F. L. HARVEY, ORONO, ME.
In his Monograph of the Sphingidae,
p. 222, Prof. J. B. Smith says the early stages of the above species are entiiel~ 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. ceryiH from Mr. Albion
Townes, Wintllrop, 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 egg's laid was about 160. The
eggs began to hatch about May 27 and
continued to emerge for about five days
making the egg period re; clays.
Mr. Ora W. Knight, who had the
care of most of the larvae and succeeded in carrying some through
all of the
cl~angcs, made the following notes :
Placed the larvde in a gauze net
upon Salix 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
picked leaves. They did not thrive
so well and many died, not having
strength to pupate. Seven entered
the pupa slate 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 Brauu secured a female
on willow in his garden, Baiigor, Me.,
which laid nearly 200 eggs, and suc-
ceccled in getting about 50 pupae fiom
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
tin's species feeding upon Balm of
Gilead. The larvae are subjected to
the depredations of parasites.
The following- description of the
eggs and laivae were made by the
writer,
A-g~rs pale green, oblate spheroid, much flattened, 2 mm. long,
Larvaejust hatched, 4 mm. long.
Apple
green, horn pdc 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.
M~/ii~e 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,

extending to the rose pink slightly granu- lated honi. Along each side above the
oblique stripes and extending from the
head to the posterior oblique stripe is a yellow band. The nature of this band is
the principal mark by which the larvae of this spccics is distinguished from that of S. geminuius. The practiced eye readily
distinguishes between the above species by this band. Fore legs pink, caudal shields darker green than the rest of the body.
Head and dorsum of next segment not
granulated. Spirnclcs yellow with a car- mine areola.
AN EXCELLENT beginning toward the nat-
ural history of our aquatic insects has just been published by C. A. Hart in the bulletin of the natural history laboratory of Illinois. We trust it is a forecast of the work to be done at the biological experiment station of the University of Illinois, where Mr. Hart is entomologifct, and next su~n~ner'i; programme of which has just been issued. The paper is chiefly devoted to Diptera, especially Tipulidae, Tabanidae and Stratiomyidae,
and is rendered much more useful by the
liberal use of keys and by excellent half- tone plates.
