This species is very closely allied to Ph. Diacis, De 

 Haan, but differs in the uniform size of the spines of the 

 head, the shorter mesothorax, and the differently con- 

 structed terminal joints of the abdomen. The head is sub- 

 quadrate, rounded at its hinder part, granulose, the gra- 

 nules arranged in lines ; eyes very prominent ; a row of 

 four, small, equal-sized spines across the hind part of the 

 head, and a small round black spot on each side behind 

 the eyes. The antennse are rather short, dark brown, with 

 numerous small luteous rings. The prothorax is finely 

 granulose, as is also the mesothorax, which is gradually 

 widened behind, and armed with a few very small spines in 

 its anterior half. The tegmina are oval, obscure, blackish 

 brown, with the inner margins paler ; the carina is coni- 

 cally elevated rather before the middle of its length, and 

 is dilated in its hinder portion into a large semicircular 

 lamina. The wings are stained blackish brown, with the 

 costal area darker, the veins varied with black or blackish 

 dots, the median vein simple. The abdomen has the fifth 

 and sixth segments wider than the preceding, and mar- 

 ginated ; the seventh and eighth are subquadrate, the eighth 



with a lobe in the middle of its hind margin ; the ninth seg- 

 ment small and conical, with the two small anal styles se- 

 tose ; the terminal ventral segments form a large operculum 

 extending beyond the tip of the abdomen, with its truncated 

 extremity subdenticulated. The fore femora are dilated, 

 and suberose along the under margin. The tibise short, 

 and dilated at the base and apex. The fouf hind legs 

 short, with the femora denticulated beneath.
