A very distinct species not very close to any other known 

 to me, and with the sexes differently coloured. The male 

 in colour somewhat resembles some of the varieties of 

 kcgubris, n. sp., but is narrower in shape and with different 

 sculpture. The dark elytra with pallid subhumeral lobes 

 will distinguish the female from the females of other 

 species having the prothorax red. In the male the red 

 portion of the prothorax is about twice as wide at base as 

 at apex. In both sexes the carina on the subhumeral lobes 

 is paler than elsewhere and the antennae are entirely 

 black. 



LOXOPLEURUS CASTIGATUS, n. sp. 

 (Plate XXIV, figs. 93, 94.) 



1^ . Basal half of liead, the antennae and the scutellum black ; 

 elytra black with two flavous stripes, the outer one continued across 

 apex almost to suture, the inner terminated at one-fourth from apex; 

 prothorax (except at extreme base), under-surface (the metasternum 

 infuscate or not) and legs (tarsi and apex of tibite black) red. 



Head with moderately small and not very dense punctures. 

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

 of third, third and fifth subequal. Prothorax very densely and 

 moderately coarsely punctate ; transverse impressions distinct but 

 scarcely perceptibly oblique ; margins not very narrow. Scutdhmi 

 transversely triangular, base entire. Elytra rather elongate-oblong, 

 sides almost perfectly parallel, subhumeral lobes small ; densely and 

 moderately coarsely punctate, with traces of a linear arrangement 

 almost to base but nowhere distinct ; with traces of feeble longitu- 

 dinal elevations. Apex of prostermim widely rounded. Fourth 

 segment of abdomen just traceable across middle. 



Length 2 (vix) mm. 



9 . Differs in having the head red except at extreme base and 

 a greater portion of the elytra flavous ; the punctures smaller 

 (especially on head) and antennae just passing hind coxae. ; fourth 

 segment of abdomen appearing as an elongate wedge on each side, 

 fovea comparatively small. 



Length 2 J mm.
