posterior lateral margins are slightly oblique, and curved inward at the 

 humerus; without any apparent carinas; the three transverse furrows pro- 

 found, dividing the middle portion, especially of the disk, into obtuse, trans- 

 verse ridges ; the anterior sulcus nuicli the shortest. Posterior legs of me- 

 dium length ; the femora thick, and a little more than usually inflated. Elytra 

 abbreviated. Abdomen of the female rather large ; valves of the ovipositor 

 conspicuous; abdomen of the male much smaller; cerci broad at base, acu- 

 minate at the apex ; within the upper cavity of the sub-anal plate is a folding 

 apparatus, which can be raised and lowered posteriorly, much like the large 

 end of a bellows. Prosternum furnished with a strong spine. Face sub- 

 vertical, the lower part curving slightly under.

Remai-k. — I have seen no specimen of this species, my generic and 

 specific descriptions being made up from Charpentier's description and

 separated into a distinct genus.
