516 Mr. G. Meade- Waldo's revision of the species of 



at once separates 0. shejfieldi from that species, which has 

 the abdomen quite smooth.

 fasciato ; clypeo, siiiu orbitali infra, pronoti niargine postico, tegulis

 broader than long, truncate at apex ; anterior margin of pronotum

A conspicuous species ; the broad clypeus and emarginate 

 coxae are very noticeable.
