longitudinal groove extending along its inner edge, enclosing a glandular pouch and 
tuft of long erectile hairs about the middle, a similar fold also along tis outer edge, 
ending in a broad lateral fringe of fine hairs opposite the pouch. Thorax woolly ; 
abdomen with the terminal segments furnished with lateral wpward-curved tufts of 
hairs ; eyes naked; palpi erect, rising above the vertex, slender, compressed, clothed

arranged in tufts placed in rows along the body from the fifth to last segment, the 
anterior segments with transversely-disposed long forward-projecting hairs, the head 
with similar hairs. Head large, armed with two laterally-disposed palmated pro- 
cesses ; anal segment also armed with two hindwardly-projected lengthened setose 
processes. 
Foop Prant or Caterrinuar.—According to Dr. Horsfeld, the larve, in Java,

* Mr. de Nicéville’s description of the larva of A. Phidippus (Butt. of India, p. 290) is quite 
erroneous, having been made from Horsjield’s figure of the larva of Discophora Celinde.
