humeri feebly developed. Abdomen beneath coarsely and rather 

 densely punctate, and sparsely clothed with very fine, short recum- 

 bent hairs, the intervals smooth and shining; first segment strongly 

 convex at middle, with a densely punctured median spot, which is 

 densely clothed with short, semi-erect, scale like hairs; last segment 

 rather broadly rounded at apex. Prosternum strongly convex, sur- 

 face sparsely punctate, the punctures fine on the median part but 

 becoming very coarse and more or less confluent at the sides, sparsely 

 clothed with a few obsolete semi-erect hairs ; anterior margin feebly 

 elevated, feebly but broadly emarginate in front, forming an obso- 

 lete lobe on each side ; prosternal process short, broad, feebly convex, 

 and without marginal grooves, the sides obliquely narrowed to mid- 

 dle of anterior coxal cavities, where they are emarginate and ab- 

 ruptly narrowed, the apex very broadly rounded. 



Female. — Difi'ers from the male in being larger and more robust, 

 and the first abdominal segment feebly convex and without the 

 densely punctured and pubescent median spot. 



Length, 18-25 mm.; width, 7-10.5 mm. 



Originally described by Fabricius (1775) from " Oriente." Man- 

 nerheim (1837) and Chevrolat (1838) both record it from the island 

 of St. Domingo, and Waterhouse (1904) states that it is apparently 

 common in St. Domingo. 



The following material has been examined. Coll. British Mus. : 

 One male and two females, labeled as follows: St. Domingo (Fair- 

 maire) ; St. Domingo (Coll. Chevrolat) ; and St. Domingo (Saunders 

 74-18). Coll. U. S. Nat. Mus.: One female, labeled "Antilles 

 (Fairmaire)" (donated by the British Museum). 



This is one of the broadest species of the genus.

 two and two-third times as long as wide, broadly rounded in front,, 

 more acuminate behind, and feebly convex above; color above black 

 or greenish-black, sometimes more or less cupreous, with the bottom 

 of the punctures more distinctly cupreous than the reliefs; beneath 

 dark aeneous to cupreous, with a strong greenish, bluish, or purplish
