438 Mr. A. M. Lea's Notes on 



slightly shorter than fifth. Prothorax densely and coarsely punc- 

 tate ; oblique impressions rather feeble ; margins narrow. Scutelliim 

 subtriangular, base entire. Elytra with small subhumeral lobes ; 

 densely and coarsely punctate, punctures somewhat smaller and 

 sparser but with scarcely a trace of linear arrangement posteriorly. 

 Apex of prodernum widely subtriangular. Third and fourth seg- 

 ments of abdomen strongly incurved to and narrow across middle, 

 fifth flattened in middle. 



Length 1^ mm. 



9 . Differs in having less of the sides flavous, the antennae shorter 

 and punctures rather smaller. Abdominal fovea very large, strongly 

 encroaching on fourth segment (which, however, is traceable across 

 middle) and very slightly on third. 



Length 2 mm.

In the male the Havous portion of the upper-surface 

 appears as a rather wide stripe extending from tlie front 

 of the prothorax to the suture at apex of elytra ; in 

 the female this stripe is much narrower and darker, 

 and on the elytra terminates just beyond the middle, 

 although there is an obscure spot on each side of apex. 



In appearance resembling the preceding species but con- 

 siderably smaller, the pale lateral markings of much 

 greater extent and with the abdomen different.

^ . Black ; lower half of head, sides of prothorax, subhumeral 

 lobes, abdomen and legs reddish. 



Head with rather large but not very dense punctures. Antennae 

 somewhat shorter than body, second joint more than half the length 

 of third, third and fifth subequal. Prothorax more than twice as 

 wide as long ; with moderately dense, regular and fairly large 

 (smaller on disc than elsewhere) punctures ; oblique impressions 

 ratber wide and distinct ; margins narrow. Scutellum triangular, 

 base entire. Elytrawiih. rather large subhumeral lobes, sides feebly 

 but distinctly incurved to middle ; densely and coarsely punctate, 

 punctures somewhat smaller but not at all seriate in arrangement 

 posteriorly. Apex of prosternum widely siibtriangular. Fifth ab- 

 dominal segment seraicircularly excised in middle.
