 finely punctate, a narrow carina running down the front, the top of 

 the head piceous, lower front deep reddish brown, sometimes even 

 pale yellow, with the mouthparts dark. Antennae pale at base and

 by Hoge, A. Fenyes, and F. Knab; Rio Antonio, Oaxaca, Mexico, 

 F. Knab, collector. Escuintla, Guatemala, and Izalco, Salvador, both

Remarks : Jacoby wrote that this species resembles Diabrotica biannu- 

 laris Harold in its elytral markings. In one specimen from Teapa, 

 Mexico, he wrote that the rings were connected along the side by a 

 dark line. I have examined one specimen marked like this which 

 bears solely the locality label "Mexico" and is a female, now in the 

 Bowditch collection at the Museum of Comparative Zoology.
