strongly deflexed, neck very small; last joint of maxillary palpi 

 large and hatchet-shaped; first joint of hind tarsi in our species

 are probably represented in the State.

XV. ELONUS Casey. 1895. 



Oblong, opaque species clothed with short hairs intermixed with 

 longer and more erect ones; head deeply constricted and strongly 

 sinuate at base; last joint of labial palpi large, suboval, truncate 

 and deeply concave at apex ; antennas with second joint short, wider 

 than third, the last joint elongate, obliquely pointed or bent. Two 

 of the three known species probably occur in the State, although 

 but one has been taken.
