shining like the skin, faint on joint 3, large and covering the hump 

 on joint 12. Tubercles moderate, very distinct, rounded, rather 

 prominent, normal, no subprimaries ; ia and ib separate, iia and iib 

 separate, iv on the abdomen behind the spiracle. Segments rather 

 weakly annulate. Tubercles i on the apex of the hump of joint 12 are 

 enlarged, separate. Sometimes there are no dorsal spots on joints 3 

 and 4. Set^e stiff, black. When first hatched the tubercles are not 

 black, the dorsal spots are dull brown and diffuse while the one on 

 the hump of joint 12 is blood red. 



Stage II. — Head rounded quadrate, angled on the lower sides, 

 flattened before, higher and wider than joint 2 ; clypeus small, vertex 

 broadly shallowly notched, erect, dark smoky brown, broadly luteous 

 in the sutures of the clypeus, vertices of lobes blackish, width .8 mm. 

 Body cylindrical, joint 12 with a conical dorsal hump, nearly as high 

 as the width of the segment ; feet moderate, the anal pair about same 

 size as the others, perpendicular, not extended backward. Segments 

 obscurely 4-annulate. Not shining, whitish with a yellowish tint, 

 translucent, the food appearing green. Cervical shield small, trans- 

 verse, smoky; dorsal patches on joints 3 to 10 small, diffuse, dull 

 brownish-red, the hump on joint 12 brighter red. Tubercles minute, 

 concolorous, obscure ; setse small, slender, short, black. Feet all 

 pale. Later the feet were testaceous, the head nearly uniformly dark 

 brown ; dorsal spots more distinct and rounded, marked in pale dots 

 by tubercles i and ii. Rarely the spots are conjoined into a monili- 

 form band, narrowed before, broken at joint 11. Still later there 

 appears a broad, opaque, white, subdorsal band. The larva rests on 

 the back of a leaf with the head curved and touching the middle of 

 the body. 



Stage III — Head higher and broader than joint 2, higher than 

 wide, convex flattened before, obliquely flattened towards vertex, 

 rounded squarish, the vertex shallowly notched ; mouth roundedly 

 projecting ; clypeus less than half to vertex ; white on each side of the 

 median suture above clypeus, else shaded with blackish luteous ; ver- 

 tices of lobes black, the patches conjoined narowly across the vertical 

 notch; labrum pale; width i.i mm. Body moderate, a little smaller 

 behind; joint 12 with a dorsal conical hump, not large. Anal feet 

 slight, used. Segments 5 -annulate. Whitish, translucent, a broad, 

 opaque white, subdorsal band, weakly contrasted ; dorsal patches red- 

 brown, forming a confused band on joints 3 to 5, streaked on the
