Diabrotica variegata Jacoby. Mexico. San Jose 

 del Cabo. There may be some doubt as to the correctness 

 of this determination, but I prefer the doubt rather than 

 a possible svnonym, as there are quite a number of species 

 similarly marked, so that comparison will be necessary 

 to correctly determine the names. The species is related 

 to -picticornis, but may be separated from that by the 

 general color, greenish-yellow, and the posterior band 

 not crossing the suture.
