disc marked witli castaneons dots and lines symmetrically arranged. 

 Tegmina with marginal field equalling half the total breadth, radial

 the apical part of the anterior margin, eleven costals, anterior ulnar 

 with five branches, posterior ulnar simple. Ulnar vein of wings 

 with four branches. Supra-anal lamina shortly produced ; sub-

This is a small species, which can be recognized by the 

 colouring of the tegmina ; in these the veins are pale and 

 the interstices filled with flavo-testaceous, in addition there 

 are numerous castaneous points situated on the veins. 

 The costal veins of the wing are somewhat irregular and 

 their ends are clavate, they are ten in number, the ulnar 

 vein has three branches and there is a prominent tri- 

 angular apical area. The anterior margin of the front 

 femora beneath are armed only with minute and close-set 

 piliform spines.

A pale testaceous species, marbled with castaneous ; 

 evidently a cryptic coloration.
