apy ee ReEporT OF THE ENTOMOLOGISTS OF THE 
body gradually assumes the characteristic wedge shape, but to a 
less degre than with many species of saw-tflies. 
The full-grown larva.— Length about 18 mm.; body tapering, 
broadest on anterior third where it measures 2.1 mm. Color 
light yellowish green to darker shades, usually imitating the color 
of the leaf upon which it is feeding. Head darker with distinct 
nearly round eye-like spot on either side and sparsely covered with 
long white hair. Mandibles black at tips; prolegs on joints 6-13. 
Body covered with spine-bearing tubercles arranged in double 
transverse rows. In each double row the anterior dorsal tubercles 
bear two spines and the posterior three.* Two dorsal tubercles — 
on the first segment of the thorax bear 5; all the lateral tuber- 
cles bear 1 and 2 spines. Dorsal spines very dark or black, lateral. 
spines pale green or white. The anal plate bears six simple and 
two bifid spines. (Plates XX VII, Figs. 1, 2 and 3.) 
Habits of the larva.— The newly-hatched larve feed on the soft 
parts of the leaf but are soon large enough to eat oblong or ir- 
regular holes through the leaf. Finally, as previously stated, the 
entire leaf is devoured with the exception of the midrib and 
larger veins. When at rest upon the upper surface of the leaf 
they are quite inconspicuous owing to the similarity of color of 
the body and leaf. They continue feeding for 10 days or more, 
finally going into the ground to pupate. eae 
Pupation.— Pupation takes place during the latter part of June. 
Last year nearly all of the larve in a badly infested field of rasp- 
berries near the Station had gone into the ground by June 29. 
When ready to pupate the larvee crawl down the canes and wan- 
der about for a time, apparently seeking a suitable place $0 enter 
the ground. Some of them enter the ground close to the canes 
but large numbers were observed to go 2 or 3 feet from 

6 From other descriptions principally by Saunders (Ont. Ent. Soc. Ann. 
Rpt., 1873, p. 12) it appears that there may be exceptions to this arrange- 
ment, but in nearly 30 specimens examined by the writer no exceptions were — 
observed.
