 hift of long erectile hairs about the middle, a similar fold also along Us outer edge, 

 ending in a broad lateral fringe of fine hairs opposite the pouch. Thorax woolly ; 

 abdomen with the terminal segments furnished with lateral upivard-curved tufts of 

 hairs ; eyes naked ; palpi erect, rising above the vertex, slender, compressed, clothed

* Mr. de Niceville's description of the larva of A. Phidippus (Butt, of India, p. 290) is quite 

 erroneous, having been made from Hoi'sjield's figure of the larva of Discophora Celinde.
