Color, pale lemon yellow, elliptico-cylindrical, .5 mm. long, surface rugulose. 
Larva. Young larva olive green, pale and sordid, .75 mm, long, head 
eapsule thinly chitinized, dusky and shining, three ocelli on either side 
black, a black spot posteriorly on either side of the median line on pro, 
meso and metathoracie nota. Body clothed with pale hairs. Legs stout. 
Full grown larva 5 mm. long, 2 mm. wide, elongate oval, flatly convex, 
color pale clay yellow, darker medially, covered dorsally with white, waxy 
secretion. Seeretes a sulphur yellow fluid from the dorsum when this is 
disturbed. Head small, transverse, labelliform, retractile, thinly chitinized 
and bearing fine hairs, ocelli two on each side, black, immediately behind 
the short, papillate antennae, which are two-jointed and setaceous at 
apex. Maxillary palpi four jointed. Labial palpi dise-like. Legs fairly 
stout. Prothorax transversely oval, narrower than the mesothorax or 
the metathorax. Abdominal segments transverse, narrowing slightly in a 
posterior direction from the metathorax. A longitudinal row of setiger- 
ous turbercles is present on the lateral margins, another within the 
margin of the metathorax and the first eight abdominal segments, three 
transverse rows of fine hairs on the pronotum, two on mesonotum and 
metanotum and a line along the lateral margins of each, a transverse 
row of hairs on the anterior margin of the first eight abdominal seg- 
ments, ninth abdominal segment with the hind margin eurved, a_ line 
of hairs along the caudal margin and a few scattered hairs'on the notum, 
ventral surface nearly naked, the foot on the venter of ninth segment.
