52 Mr. F. P. Pascoe on some new or little-known 



the form of the prosternum and its contiguity to the mesosternum. 

 My specimen is the only one T have seen, and was obtained from a 

 small collection sent to this country by Mr. Thwaites, the Superin- 

 tendent of the Botanic Garden at Peradenia.

 (common apparently to the genus) ; scutellum small, rounded poste-

Head broadly triangular, as wide as the prothorax. Eyes distinct, large, 

 ovate, contiguous to the prothorax. Antenna? arising from beneath a

 short, with a single tooth in the middle. Palpi robust, claviform. 

 Maxilla? with two ciliated lobes. Labium small, subcordate. Mentum 

 transverse. Prothorax subquadrate, posterior angle emarginate, the 

 parapleural distinct. Elytra as broad as the thorax, tapering posteriorly, 

 the epipleural plait very narrow. Legs short ; anterior coxa? conical, 

 contiguous, their acetabula closed behind, the intermediate subapproxi- 

 mate, oblique, furnished with trochanters, the posterior transverse ;
