106 MANDIBULATA. COLEOPTERA. 



Genus CCCXIV. — Leiosoma, Kirhy. 



Antennm geniculated, 12-jointed, rather short and stout, the scape not reaching 

 to the eyes ; funiculus 7-jointed, the basal joint elongate, obconic, second 

 rather shorter, also obconic, the remainder very short, transverse, gradually 

 increasing in width to the club, which is oblong-ovate^ rather acute. Rostrum 

 deflexed, stout, rather long, longitudinally striated : eyes ovate : thorax oblong, 

 rounded, with the base and apex truncate : scutellum very minute, triangular : 

 elytra united, ovate, deeply punctate, the punctures disposed in strise: femora 

 clavate, with an obscure tooth : tibice with a small horizontal hook at the apex 

 ■within : body ovate, hard, apterous. 



Exclusively of the punctate-striate elytra of this genus, the arti- 

 culations of the antennae are slightly different from those of Molytes, 

 and the minute bulk of the only species evidently points out its 

 distinction from the genus last mentioned; like which the exterior 

 integuments of the body are extremely hard, so as with dilBculty 

 to be pierced with a fine pin.

 Cu. punctatus. Mar sham. — Le. punctata. Steph. Catal. 170. No. 1740.

AntenncE ^enicvlsiiedi, 12-jointed, rather short and slightly thickened; the scape 

 not reaching to the eyes; funiculus 7-jointed, the two basal joints rather long,
