mesopleurae, except medicJly, rugoso-punctate, middle finely sparsely punc- 

 tured ; abdomen rugoso-punctate, basally the rugae more or less longitud-

 carina, posterior face surrounded by a carina, the median carina pro- 

 longed into a short spicule where it meets the carina surrounding the pos- 

 terior face ; mesopleurae with coarse punctures, along the upper portion

Described from 1 specimens collected by Mr. Albert Koebele and

 Bruchus sp. in Prosopis pubescens collected at Indio, California, and the 

 specimens are labeled San Diego County, California, but Indio is now in 

 Riverside County.
