182 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



Types. — Holotype, United States National Museum No. 52380, col- 

 lected by Jose H. Pazos. (This specimen was the paratype of O. 

 bitscki recorded by Notman.) Also 10 paratypes from localities 

 listed below, which are deposited in the United States National 

 Museum and the Museum of Comparative Zoology. 

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



Cuba: San Antonio de los Banos (Pazos, in U.S.N.M.), Buenos Aires, Trinidad 

 Mountains (Darlington, in M.C.Z. and U.S.N.M.), Rangel Mountains (Darling- 

 ton, in M.C.Z. and U.S.N.M.), Imias (Darlington, in M.C.Z. ), Soledad 

 (Darlington, in M.C.Z.). 



/Specimens examined. — I have seen only the 11 types. 



Remarks. — This species seems to be quite distinct from huscki by 

 its rounded clypeus, its less alutaceous pronotum, and its scattered 

 punctures on the anterior tibiae. It was recognized as probably 

 distinct in the National Museum collection by Dr. Chapin. 



One additional specimen from Rangel Mountains differs from the 

 others in having the pronotal punctures distinctly coarser. This 

 difference appears to me to be much too slight to warrant separating 

 it specifically, since only the size of the punctures is involved, not 

 arrangement or density or shape. 



I have no record of its habits. 



9. OSORIUS STUICTUS, new species 



Description. — Rufopiceous. Head five-sixths as wide as prono- 

 tum; the eyes moderately prominent; the clypeus feebly rounded, the 

 angles not prominent, somewhat indistinctly crenate; labrum large, 

 feebly emarginate both above and below the declivity, alutaceous; 

 apical antennal segments nearly as wide as long; with sparse moderate 

 punctures and a few large ones obscured by strong alutaceous ground 

 sculpture. Pronotum one-eighth wider than long, rather strongly 

 narrowed behind middle, base seven-eighths as wide as apex; sides 

 distinctly emarginate before basal angles; lateral margin distinctly 

 enlarged and recurved at basal angle; without trace of midline; 

 with fine and shallow punctures separated by three to five times 

 their diameter; feebly alutaceous throughout. Elytra very nearly 

 as wide as pronotum, as long as wide; coarsely coriaceous and im- 

 punctate except for a few large punctures. Abdomen witli aluta- 

 ceous sculpture on each segment but obsolescent at apex of each ; with 

 moderately coarse but sparse setigerous punctures, denser apically. 

 Anterior fa^e of front tibia with setigerous punctures scattered. 

 Length, 8 mm. 



2'ype locality. — Cuba, mountains north of Imias, in eastern Oriente 

 Province, elevation 3.000 to 4,000 feet. 



Types. — Holotype, Museum of Comparative Zoology, collected by 

 Dr. P. J. Darlington on July 25-28, 1936.
