ZlLORA, Muls. 



The genus Zilora may be distinguished from the other 

 genera of the melandryini of our fauna by the following 

 characters : — 



The antennas are slender, not suddenly enlarged ; frontal 

 suture indistinct ; maxillary palpi have the last joint wider 

 than the preceding joints and securiform. The front coxse, 

 which are contiguous, are without trochantin, and the acet- 

 abula have on the outer side a distinct fissure ; the middle 

 coxae are separated, and the body clothed with erect hairs. 



Only two species are known to me as occurring in the 

 northern parts of America, one of which has been described 

 from Canada. They appear to be rare.
