19. OSORIUS MINOR Notman 



Osorius minor Notman, 1925, pp. 7, 14, 25. — Scheerpextz, 1933, p. 1134. 



Descnption. — Dark rufopiceous. Head nine-tenths as wide as pro- 

 notum; eyes moderately prominent; clypeus feebly emarginate in 

 front, angles feebly tuberculate ; labrum feebly emarginate above de- 

 clivity, alutaceous; outer segments of antennae as wide as long; 

 with numerous large punctures; densely strongly alutaceous. Pro- 

 notum one-ninth wider than long, strongly narrowed posteriorly; 

 base nearly five-sixths as wide as apex; sides feebly arcuate and 

 very slightly sinuate, posterior angles rounded; lateral margin not 

 wider posteriorly; with an impressed middle band set off by serial 

 punctures; with very coarse frequently elongate punctures, goner- 

 ally separated transversely by less than half their width ; very obso- 

 letely alutaceous. Elytra scarcely wider than pronotum, a little 

 wider than long, not much enlarged posteriorly; with moderately 

 large punctures, frequently serial and somewhat united; coriaceous 

 but not alutaceous. Abdomen ver}^ vaguely alutaceous; punctures 

 rather large, often submuricate. Anterior face of front tibia with a 

 very few scattered setigerous punctures. Length, 4 mm. 



Type locality. — Trinidad, ward of ISIontserrat in the county of 

 Caroni. 



Types. — Holotype in the United States National Museum (No. 

 27330). 



Records. — The following are the records known to me: 



St. Vincent: (British Museum). 



Grenada: (British Museum; Cameron collection). 



Trinidad: Montserrat (Notman, 1925, U.S.N.M.). 



Specimens examined. — I have seen the unique type in the United 

 States National Museum, 18 examples in the British Museum, and 

 2 in Dr. Cameron's collection. 



Remarks. — This species is similar to latipes but is distinct by its 

 strongly alutaceous head. It is possible that this will eventually 

 be found to fall within the ranges of variation and distribution of 

 latipes., but at present it is best retained as distinct. 



The specimens in the British Museum and in Dr. Cameron's col- 

 lection were labeled OsoHus parens Sharj:). O. minor differs from 

 the Central American specimens in its smaller size, less distinct elytral 

 punctation, its obsolescent abdominal sculpture, and the less distinctly 

 bidenticulate angles of the clypeus. 



I find no record of the habits of this species.
