 eyes with sides completely rounded into base; eyes at barely their 

 length from base; in front with a median longitudinal impression 

 nearl3^ one-half as long as head ; with large and impressed punctures 

 sparsely scattered at sides; with fine strigulose ground sculpture. 

 Pronotum about one-eighth longer than wide, widest near front, 

 feebly emarginately narrowed posteriorly to rounded basal angles; 

 discal series with five punctures, and with about five lateral punc- 

 tures; ground sculpture as on head. Elytra with punctures rather 

 small and dense, generally separated by distinctly less than their 

 diameter, the bottom of each appearing granulate; surface even, 

 without ground sculpture. Abdomen with very sparse and fine, often 

 submuricate punctures; without distinct ground sculpture but with 

 iridescent lustre. Male., unknown. Female., eighth sternite rounded.

Type locality. — Dominican Republic, San Francisco Mountains. 



Types. — Holotype and one paratype, females, U.S.N.M. No. 52463, 

 collected on "6.9.05" by August Busck. 



Records. — The following is the only record to me : 



Hispaniola: Dominican Republic (Busck, in U.S.N.M.). 



Specimens examined. — I have seen only the two types. 

 Remarks. — This species is distinguished by its dense granulate 

 elytral punctures and by its uniform black color. 

 I find no record of its habits.
