180 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



Remarks. — The specimens from Momit Basil in northern Haiti are 

 reported by Darlington to be somewhat different from the types. The 

 sinuation of the sides of the pronotum is not sufficient to make a clear 

 distinction between this and crenuUfrons.^ but in the latter the sides 

 at base are less explanate, the hind angles not prominent externally, 

 and the base is not feebly emarginate. 



The types were taken "in thick leaf mold in wet cloud forest."

Osorius hirtilahris Darlington, 1937, pp. 284, 286, 292. 



Description. — Piceous. Head about nine-tenths as wide as pro- 

 notum; eyes very prominent; clypeus truncate, anterior margin 

 crenate (serrately) ; labrum long, truncate, with rounded angles, 

 alutaceous basally, swollen and shining anteromedially ; antennae 

 slender; surface minutely punctulate and finely alutaceous. Pro- 

 notum one-third wider than long, strongly narrowed behind, base 

 barely three-fourths as wide as apex; sides arcuate anteriorly, sinu- 

 ate posteriorly; lateral margin much broader basally; without dis- 

 tinct median line; sparsely punctate; with only a trace of ground 

 sculpture. Elytra as wide as pronotum, scarcely longer than wide, 

 not much enlarged posteriorly; humeral margin feeble; with a very 

 few large setigerous punctures; coriaceous. Abdomen moderately 

 densely punctate, not distinctly alutaceous except at base. Anterior 

 face of front tibia with setigerous punctures scattered. Length, 9 to 

 11 mm. 



Type locality. — Southwestern Haiti, "northeastern foothills of the 

 Massif de la Hotte, 2,000-4,000 feet." 



Types.— Holotype (M.C.Z. No. 20236) and 16 paratypes in the 

 Museum of Comparative Zoology; 2 paratypes in the United States 

 National Museum (No. 51250). 



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



Hispaniola: Haiti, Morne La Hotte (Darlington, 1937; M.C.Z. ; U.S.N.M.), 

 Miragoane (Darlington, 1937), KenskofE (Darlington, 1937). 



Specimens examiTied. — I have seen only the two paratypes in the 

 United States National Museum and one from the Museum of 

 Comparative Zoology. 



Remarks. — Very distinct by the unusual characters of the labrum. 



The types were "taken struggling in a pond of flood water in 

 scrubby (formerly rain-forest) country."
