frontal stria, liou'ever, is not circular, the disc o£ the thorax 

 is smooth, the pyo-idia are less closely ])uncturedj the meso- 

 sternum is more finely marginata, and the transverse stria is 

 not crenulate; the metasternum has a few punctures at the 

 base placed transversely near the coxae. 



E. bi-eviusculus, Mars, (which has a wide distribution from 

 the Cape to the Congo River), has the tratisverse meso- 

 sternal stria finely yet markedly crenulate ; but Marseul did 

 not refer to it. 'J'he sutural stria in both species joins the 

 fourth dorsal at the base.

I believe that only one example of this American species 

 is known, and it is therefore desirable to give a woodcut of it.
