11. Roggeveenia buxtoni, sp. n. (Text-figs. 7, 8, 9.) 



Male : 10-5 mm. long ; 3 mm. wide. 



Elongate, castaneous, with the vertex and an indefinite median area of 

 the pronotum darker ; the base of the elytra flavous, with the basal margin 



and the circumference of the scutellum nearly black. 

 Antennae dark castaneous. Pubescence moderately fine, 

 short, ashen white. Front feebly convex, closely and 

 coarsely punctate. Antennae with third and fourth 

 joints similar and of about equal length, feebly serrate. 

 Prothorax depressed on disc, longer than wide. Sides

 margin. Punctuation fine and close. Posterior angles 

 strong, divergent, feebly bicarinate, the inner carina 

 the stronger. Base of prothorax not canaliculate. Sulci 

 obsolete. Scutelmm declivous, subogival, convex, very 

 finely punctate. Elytra slightly wider than prothorax 

 (except posterior angles), parallel to about middle,
