This species is distinct by its elongate and compressed form and 

 its pale semi-hyaline tegmina.

This genus, judging from the unique typical specimen now 

 before me, has been founded on a mutilated specimen. Buckton 

 writes : " may be distinguished by its almost obsolete posterior 

 horn and by the curved neuration of the tegmina.'* The first 

 character does not exist and was des(;ribed from the mutilated 

 type now in my collection. The posterior jirocess is slender, 

 closely impinging on the tegmina and extends to or beyond the 

 posterior angle of the inner tegminal margin ; the veins to the 

 apical areas of the tegmina are strongly curved inwardly, and this 

 character will separate Fogon from Otlnotus to which it has a 

 strong superficial resemblance.

Buckton's mutilated type is here figured and I add his original 

 description : — " Suprahumerals stout and thorn-like, recurved and 

 divergent. .Scutellum exposed and conspicuous " (this is only con- 

 sequent on the mutilated posterior pronotal process). "Posterior 

 horn very short, not so long as the scutellum and like it cleft at

 paler brown in colour, with darker fuscous waved markings, which 

 are partly followed by the curved dark neuration. The fine apical
