Clcisely allied to .1. ilorbtyntjt Uuer., but. may be distiugaislied by the entirely 

 Ijlack thorax, the well-developed costae, aud the positiou of the spots on the elytra, 

 which are situated even liirtlier from the base than in A. humiruUs. 



An AlariMs in the British Museum, from Veragua, seems to be referable to this 

 species; it differs in the spots of the elytra being obsolete, but perfectly agrees iu 

 other respects.
