 Shields and tubercles obsolescent, sette minute except at the extremities. Green; 

 dorsal line narrow, white, obscure; lower subdorsal rather broad, distinct, white, 

 shaded with orange, angled on the hump on joint 12; the two substigmatal lines par- 

 allel, waved, subconfluent by mottlings, forming a broad, shari)ly edged ])and cen- 

 tered with brown and shaded with orange in spots. Other lines broken, dotted, con- 

 fused with strigaj. Dark brown subdorsal patch on joint 3 and lateral ones on joints

Starie V. — Head as before, shining brown, reticulate with darker t)n the sides, the

 mottled reticulate with brown and whitish dots, the lines obsolescent, lost in the 

 mottlings, except the lower subdorsal, which persists as a series of white dashes on 

 the centers of joints 3 to 12, each dash forming the lower edge of a triangular brown- 

 black patch, those of joints 3 and 12 the largest, the central ones smaller and some- 

 times not developed. A lateral patch on joints 5 and 11. Upper subventral line 

 indicated, narrow, waved, reddish. Dorsal line indicated, distinct on joints 2 and 

 3. Cervical shield olivaceous brown with three pale lines; anal plate concolorous; 

 feet greenish; slight irregular black dottings on joint 13 dorsally. 



Sta(je VI. — Head broad, rounded, bilobed, clypeus large, reaching over two-thirds 

 to the vertex; brown, marked as before, the reticulations not prominent; not retracted 

 in joint 2; width, 3""". Body cylindrical, normal, gently enlarged at joints 3 to 5 

 and 12, tapering only at joints 2 and 13; feet moderate, normal. Densely and finely

 on 11 halfway to tubercle v, on 12 at the lower angle of the spiracle. — [H. G. Dyak.]
