The unique male of this species in the Hopeian Collec- 

 tion is considerably more slender than that of Ph. Py- 

 thonius, with longer legs, the head larger and flatter, 

 and the mesothorax unarmed. It is also closely allied to 

 Ph. Hypharpax, but has the wings and mesothorax con- 

 siderably longer, and the terminal abdominal segments dif- 

 ferently constructed. The head is oblong, wider than the 

 prothorax, flattened above, the posterior angles rounded, 

 and the hind margin suddenly deflexed ; between the eyes 

 in front is a short transverse curved impression. The eyes 

 are large and prominent. The antennae moderately long, 

 with about twenty-four joints, the middle ones long. The 

 mesothorax long, very slender, and simple. The tegmina 

 are elongate-ovate, constricted before the middle, with the 

 median carina elevated into a strong obtuse conical lobe. 

 The wings are long and narrow ; they are hyaline, slightly- 

 tinged with brunneous, with dark brown longitudinal veins; 

 the costal area darker, especially towards the anterior mar- 

 gin, the margin itself towards the base with a luteous 

 stripe ; the transverse veins are very distinct, and the me- 

 dian one simple. The abdomen is long, slender, and 

 simple ; the seventh joint two-thirds of the length of the 

 sixth, and gradually widened ; the eighth gradually nar- 

 rowed ; the ninth more attenuated, compressed, longitudi- 

 nally cleft ; the apex truncate, the two divisions spinulose 

 within, and the anal styles deflexed ; the three terminal 

 ventral segments are short and gradually thickened, extend- 

 ing only to the middle of the eighth dorsal segment. The 

 legs are long and slender, the whole being serrated ; the 

 four posterior tibiae with a small lobe near the middle of 

 the upper margin ; the basal joint of the tarsi longer than 

 the rest united.

Very long, slender, filiform and cylindrical ; luteous brown, 

 beneath greyish white. Head rounded and very convex, 

 destitute of spines. Eyes prominent. Antennae long, 

 slender, finely setose ; joints short and very numerous. 

 Mesothorax much thinner than the width of the head, co- 

 vered both above and beneath with numerous minute black 

 points. Tegmina small, oval, subtruncate at the tip, with 

 a strong rounded elevation between the base and the middle 

 of the central carina ; the inner angle of the extremity is 

 marked by a triangular brown patch. Wings long, rather 

 narrow, subhyaline and whitish, slightly stained with dusky 

 along the margin and at the extremity ; longitudinal vein 

 light brown ; costal area luteous grey, varied with minute 

 darker cloudings, and with a long whitish streak extending 

 from the base to about the middle of the costa, with the 

 first and second post-median veins uniting with the median 

 before the extremity of the wing. Legs long and simple, 

 mottled with grey and brown ; four posterior femora with 

 the apical angles dilated and terminating in a small acute 

 point on each side ; all the tarsi have the basal joint long 

 and carinated on its upper edge, the carina being emar- 

 ginate near its extremity. Abdomen long and slender ; 

 three terminal joints short, scarcely wider than the rest, 

 the last joint subtruncate at the tip, with the angles rounded
