 closely punctured, those on the vertex larger and more separate ; middle 

 fovea elongate, but not strong ; only the lateral postocellar furrows present ;

Type, No. 12762, U. S. N. M. 



Closely allied to /. Kiiicaidi Koh., but the hbrum is rounded at the 

 aj)ex, there is a shining area on lower inner orbits, and the antcnn.e are 

 pale.
