basis of the vasa interna. In its first fifth the third ulnar rib runs close 

 to the first vas internum ; it is then curved outwards, and sometimes 

 receives a simple supplementary vein from before. Shortly after this, 

 it either becomes trifid or is resolved into an anterior simple, and a 

 posterior bipartite vein. The posterior of the moderately straight vasa 

 interna sends a recurrent vein towards the base of the wing. From 

 the costa to the vas ulnare inclusive the reticulation is well defined. 

 Forceps of ^ slender and jointless (apparently). Legs feeble and 

 short. The two caudal setas are horizontally patent in the dried .

In this species the cross-veinlets are numerous throughout the 

 extent of the anterior wings ; and the forceps of the are moderately 

 stout and two- or three-jointed.

The anterior ulnar rib is bifid, and is met in front, near its base, 

 by a bipartite supplementary vein whose fork includes several veinlets. 

 The fork of the rib includes one supplementary vein. Second ulnar 

 rib simple. The posterior division of the bipartite third rib is itself 

 bipartite, and is followed by upwards of four supplementary veins. 

 These are succeeded in their turn by some irregular veinlets from the 

 internal margin. The recurrent vein from the robust second vas in- 

 ternum receives two or three simple veinlets from the inner margin. 

 Yasa interna moderately straight, and simple. Eeticulation rather fine. 

 Forceps of ^ four-jointed ; their second joints the longest.
