The youug larva, which hatches in six or seven days, is 

 .08 of an inch long, cylindrical, tapering from joint 3 ; 

 pubescent, and of a pale translucent green color. The 

 head is twice as broad as the second segment, subglobose, 

 bilobed, the surface thickly pitted with yellow excava- 

 tions ; color shining yellow or ochrey brown. Towards 

 the last of the stage the body is less tapering, each 

 segment well rounded, with dark green dorsal and sub- 

 dorsal lines, the last more decidedly green. After six 

 days the larva moults, when it is .14 of an inch long, 

 the body a little thickened at joint 7, tapering slightly 

 each way, the last segment ending in a forked tail. 

 The surface is closely covered with yellow and yellow- 

 white tubercles, arranged in longitudinal rows, and 

 also in regular cross-rows. These tubercles are stout 

 at the base, subconic at the top, of irregular size, and at 

 the top of each is a short white appendage. Dorsal 

 and subdorsal stripes dark green, the last narrow. The 

 dorsum is covered by two bands of tubercles, divided by 

 the green stripe, each band made up of two rows, the 

 outer row whitish, the inner yellow. The subdorsal 

 region, or below the lateral stripe, is another band of 

 two rows, and as the stage proceeds these separate, show- 

 ing a dull green line between them, the lower row run- 

 ning with the basal ridge of the body. The tails are 

 divergent from base, short, tapering, rough with tubercles, 

 and these give out longer hairs than elsewhere. Under 

 side, feet, and legs yellow-green. Head subquadrate, the 

 sides rounded, the whole surface shallowly pitted and 

 covered with short yellow down ; color greenish white, 

 with dark brown spots and patches, a large brown tri- 

 angle over the mandibles, a small subtriangular patch at
