annulets, on 6 to lo and 12 forming neat round spots, very slightly- 

 elevated, marked in white by tubercle i and an annulet groove ; a 

 slight dot on joint 11 and on 13 anteriorly ; the spots of joints 6 and 7 

 are produced backward a little on the dorsal line. No shields ; tuber- 

 cles and setffi obscure, concolorous, whitish. Another larva had the 

 head white with brovvn-black dots at the apex of each lobe and on eye ; 

 subdorsal band yellowish ; dorsal spots smaller, finally fading out ex- 

 cept for tiny paired dots. The subdorsal line is widened and yellow- 

 blotched on the segments and there is a narrow suprastigmatal white 

 line and traces of a fine lateral one. 



Sfa^i^e IV. — Head shaped as before, held obliquely ; yellowish- 

 green over the lobes, clypeus and a space below the ej^es greenish ; a 

 small, neat, elliptical, black patch on the summit of each lobe; eyes 

 in a small black spot ; labrum whitish, jaws yellowish at base, an- 

 tennae very small and pale; width 2.5 mm. Body slender, cylin- 

 drrcal, joint 12 with a sharp, triangular dorsal hump, more oblique 

 before than behind, not as high as the diameter of the segment ; seg- 

 ments coarsely 5 -annulate, the incisures depressed. Feet normal, 

 equal, resembling Lophodonta. No shields ; transparent green, pulsa- 

 tions of dorsal vessel visible ; an opaque subdorsal band, widened 

 dorsally in the centers of the segments to touch its fellow, white on 

 the edge, yellow below, the color darkest centrally on the segments ; 

 tip of hump on the anterior slope dark red or a blackish-red dorsal 

 patch on the second annulet on joints 8 to 10 also. A narrow, 

 straight line just below the broad subdorsal line and in part fused with 

 it ; similar lateral and suprastigmatal lines uniformly pale yellow. 

 Tracheal line visible ; spiracles whitish ; no marks below ; set?e short, 

 whitish, the tubercles invisible. Later the dorsal spots faded to a 

 faint vinous shade, but leaving a dark dot on tubercle i. In the pale 

 larva a narrow white line appeared subventrally. The larva rests on 

 the vein of a leaf, the body curled in a half spiral, the head crossed 

 over the middle of the body and elevated. 



Stage V. — Head rounded, higher than wide, vertex retreating, 

 shallowly notched ; clypeus small, slightly depressed, labrum incised 

 at sides, emarginate, with the mandibles forming a rounded, project- 

 ing mouth ; pale green, slightly shagreened, yellow shaded outwardly 

 on the lobes and each side of median suture ; a rounded black patch 

 on summit of each lobe, over eye and covering distal three fourths of 

 jaw; clypeus deeper green ; antennee small, slender, pale; width 3.5
