232 Mr. H. ^Y. Bates' Supplement to the 



Much resembles L. amahilis ; differing only in being 

 still more elongated, the sides of the thorax much straighter, 

 and the black spots of the elytra differently arranged. 

 These spots consist of a round one near the scutellura, a 

 sutural stripe ceasing long before the apex and much nar- 

 rowed near the scutellum, a broad fascia (dentated on its 

 margin) behind the middle, and two lateral spots, one 

 before the fascia (and separated from it) and the other 

 behind the fascia and nearly blended with it; a black 

 border extends from the humeral callus to the hindmost 

 spot, leaving the apex, like the rest of the ground colour, 

 clear o-ray. The apex itself is obliquely trimcatcd, and the 

 elytra are tapering ; the surface has a very fine punctua- 

 tion. The thorax is unusually long, and the sides remark- 

 ably straight fi-om the fore-margin to the spine, which is 

 situated very near to the hind angle.

 Agrees with Mexican examples.

One example. 



The largest species yet described of this genus. Eather 

 densely clothed with erect hairs. Head red, sparingly 

 punctured. Antenna black ; underneath ashy-pubescent. 

 Thorax as wide as the head, moderately grooved trans- 

 versely in front and behind ; sides obtusely tuberculated 

 in the middle ; disk forming a sharply-elevated quadrate 

 plate, deeply gTooved all round, black, with a dense brush 

 of black hairs ; the black colour extending to the base and 

 over the scutellum. Elytra as wide as the thorax, elon- 

 gate, parallel, above nearly plane, punctulated partly in 

 rows; blood red, ■v\'itli a spot on the humeral callus, and 

 the apical fourth black, the apical patch with a straight 

 transverse anterior margin.
