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



the four basal joints of antennfe red ; elytra (base, suture, and sides 

 black) flavous. 



Head densely but not coarsely punctate, base strigose. Antennse 

 thin, slightly longer than body, second joint more than half the 

 length of third, third distinctly sliorter than fourth and much 

 shorter than fifth. Prothorax scarcely twice as wide as long ; 

 moderately densely and rather coarsely punctate ; front gibbous ; 

 oblique impressions fairly deep ; margins narrow. Scutellum 

 triangular, base entire. Elytra briefly oblong, subhumeral lobes 

 large ; densely but not very coarsely punctate, punctures almost 

 regular in arrangement throughout but seriate only close to apex. 

 Apex of prosternvm widely rounded. Third and fourth segments 

 of abdomen strongly incurved to and narrow across middle. 



Length 3^ mm. 



$ . Stouter, antennae distinctly shorter than body and punctures 

 rather smaller. Fovea moderately large, distinctly encroaching 

 upon fourth segment, which is not traceable across exact middle. 



Length 4^ mm.

The dark sutural marking is dilated from about the 

 middle to the apical fourth and then suddenly contracted. 

 The colour (there are seven specimens before me), except 

 for slight variation in the widths of the elytral markings, 

 appears to be constant and is alike in both sexes. 



In appearance somewhat resembling the preceding species 

 but larger, the scutellum of different shape and the third 

 and fifth joints of antennse differently proportioned.

^ . Black with a metallic-green gloss ; mandibles (tips excepted), 

 sides of prothorax (at base the reddish portion advanced more than 

 half-way to the middle), legs (tarsi infuscate) and apex of abdomen 

 reddish ; elytra (except at base sides and suture which are black) 

 almost flavous. 



Head very densely punctate and strigose. Antennae as long as 

 body, second joint half the length of third, third distinctly shorter 

 than fifth. Prothorax densely and coarsely punctate ; oblique im- 

 pressions feeble ; margins rather narrow. Scutellum triangular, base 

 distinctly notched. Elytra rather briefly oblong, subhumeral lobes 

 small ; punctures as in the preceding species. Apex of 'prosternum
