28 PITHAURIOPSIS. 



renders P. stvammeipennis most readily distinguishable from P. murdava, in 

 which the downy clothing is, as has already been stated, yellowish-oliva- 

 ceous. 



The genital armature, which has been carefully examined in several 

 specimens of each species, though identical in general plan, yet differs greatly 

 in detail in the two. 



Several hundreds of specimens of each species have passed through 

 our hands."

GENUS XIV. PITHAURIOPSIS. 



Pithauriopsis, Wood-Mason and de Niceville, J. A. S. B., 1886, p. 387. 



" Male. Closely allied to Pithauria, Moore, but differing, in the forewing, 

 in the distance between the origins of the second and third median nervules 

 being greater, instead of less than that between those of the first and 

 second, in the submedian nervure being strongly sinuated when it comes 

 into relation with, and the internal area expanded opposite to, a prominent 

 bilobed discal glandular organ, extending from the root of the first median 

 nervule for a short distance into the internal area, and consisting of two 

 unequal slight depressions of the wing-membrane, separated from one 

 another by the interno-median fold, and converted by over-arching stiff 

 modified scales into pouches, which are filled with a soft, fine, adhesive 

 brown woolly substance : and, in the hindwing, in the first subcostal nervule 

 being at its origin strongly arched towards the costal, and the base of the 

 second slightly bowed into the cell and more acutely angled at its junction 

 with the disco-cellular nervule, in the subcostal, in fact, with its branches 

 having the shape rather of a tuning-fork than of the letter Y ; discoidal 

 nervule absent, and only one disco-cellular consequently present, as in 

 Pithauria. 



The male genital somites and appendages, though at first sight 

 appearing very different, yet when carefully examined are seen to be built 

 on the same plan and to differ in characters of specific value only from those 

 of Pithauria. 



Female unknown." (Wood-Mason and de Niceville, I. c.)

" *b. Upperside, both wings rich bronzy-brown. Forewing with a basal 

 streak on the costa, another in the cell, one in the submedian, and a fourth, 

 the longest of all, filling the interno-median interspace, all composed of long 

 yellowish-olivaceous hair-like scales ; two oblong spots placed obliquely 

 at the end of the cell, the anterior one the further from the base of the 

 wing ; two subcostal spots, the anterior one a mere dot ; an oval or
