Allied to E. subcylindricus, but most variable ; the 2 speci-

Ischyrus Bahige, sp. n. 



Pallide fulvus, oblongus, capite pectoi-e geniculisque nigris ; 

 thorace crebrius sat fortiter punctato, punctis 4 transverse positis,

 ■sersus nigris, macula postica in siugulo triangulari, ad suturam

Ischyrus fraternus. 



Ischyrus frater mis, Lac. Erot. 124.

Ischyrus pallidior, sp. n. 



Pallide ochraceus, subellipticus ; capite tlioraceque subtiliter 

 punctjitis, illo antice nigro, vertice ochi'aceo, vitta nigra ; hoc
