 slender, curved, and setose. Tegmina small, narrowly oval. 

 Wings rather small, scarcely extending to the middle of

 the tip ; middle and hind femora with two small spines

I have only seen a single female of this species, which is 

 closely allied to Ph. brachypterum of De Haan (pi. 13. f. 2), 

 from which, hpwever, it differs in being more slender and 

 smaller, the legs thinner and more elongated, and the wings 

 considerably longer, reaching nearly to the middle of the 

 fourth abdominal segment. The general colour is an ob- 

 scure rusty brown. The pro- and mesothorax granulose. 

 The head oblong. The antennae long and very slender, 

 with the two basal joints dilated and flattened. The me- 

 sothorax is rather more than four times the length of the 

 prothorax ; it is very slightly, but gradually, widened from 

 the front to the base of the tegmiua, which are oval, with 

 the median carina scarcely elevated. The wings are opake 

 whitish, with fine brown veins ; the costal area brown, 

 slightly clouded with darker shades. The abdomen is 

 simple ; the terminal segments slightly dilated ; the apical 

 one truncate and slightly emarginate. The operculum is 

 simple, boat-shaped, pointed at the tip, and not extending 

 to the middle of the ninth ventral segment.
