 elongatis et quartam partem disci includentibus. Segmenti 

 primi ventralis cannula paulo breviori. Pedes validi, elongati, 

 tibiis apicem versus incrassatis 



J". Fronte quadratim valde producto, isto processu medio 

 impresso et summo sericeo, epistomate utrinque obtuse et medio 

 acute producto; antennarum articulis 1° tribus sequentibus simul 

 sumptis longitudine fere a?quali, crasso, subcylindrico, insuper 

 leviter sinuato et intus apicem versus sulcato, clava majori: meta- 

 sternum fere totum valde impressum; trochanteribus intermediis
