 long, with rounded sides, oblique anterior angles and a small tooth at 

 basal angle, a small pinched-in depression near this basal angle, surface 

 very shiny and very finely punctate, pale yellow. Scutellum reddish 

 brown. Elytra moderately convex with transverse depression below 

 basal callosity, polished dark violaceous blue and very finely punctate.

Type, male, USNM 66198, collected at Clarendon, Portland Ridge, 

 north side, July 23, 1958, by T. H. Farr; one female collected at 

 Hanover, Bloody Bay, February 15-24, 1952, by F. A. McDermott. 



Kemarks." — This is the second species of Homoschema to be found 

 on Jamaica. It differs from H. jamaicense in having a more trans- 

 verse prothorax with a little depression on each side near the basal 

 angle. The aedeagus also is different and, in its long narrow point, 

 suggests that of H. hoffmani from Haiti.
