angles not prominent; labrum short, coarsely alutaceous; outer 

 antennal segments transverse; rather coarsely and densely but very 

 shallowly punctate ; not alutaceous. Pronotum one-fourteenth wider 

 than long, rather strongly narrowed posteriorly, base five-sevenths as 

 wide as apex, basal angles rounded; with narrow and indefinite 

 median impunctate stripe; with coarse, shallow punctures, generally 

 separated by less than their diameter; not alutaceous. Elytra as wide 

 as pronotum, one-fifteenth longer than wide, sides nearly parallel; 

 with very indefinite shallow punctures obscured by coriaceous texture; 

 not distinctly alutaceous. Abdomen with moderate but dense punc- 

 tures; coriaceous but not alutaceous. Anterior' face of front tibia 

 with an indefinite series of setigerous punctures. Length, 2 mm. 



Type JocaUty. — Cuba, Cayamas, about 15 miles west-northwest of 

 Cienfuegos, province of Santa Clara. 



Types. — Holotype and one paratype in the United States National 

 Museum (No. 26337). 



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



Cuba: Cayamas (Notmau, 1925; U.S.N.M.). 



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

 a third specimen. 



Remarks. — With the types of this species I have associated the 

 specimen that Notman recorded as 0. micros Sharp. I can find 

 nothing to distinguish it except its length of 3 mm. I have compared 

 this specimen {micros of Notman) directly with the type of micros 

 Sharp in the British Museum and made the folloAving notes at that 

 time: "It (Notman's specimen) differs in lacking the two discal rows 

 of very strong punctures, and in lacking the dense ground sculpture 

 of the head. The elytra are not so coarsely and irregularly punctured. 

 Pronotum also lacks ground sculpture." The size of the type of 

 micros Sharp is 3% mm. O. micros Sharp should therefore be 

 removed from our list, and the O. micros of Notman should be placed 

 as a synonym of exiguus Notman. 



I find no record of the habits of this species. 



32. OSORIUS EXALATUS, new species 



Description, — Rufocastaneous. Head as wide as pronotum; eyes 

 very small, scarcely prominent though abrupt ; clypeus produced into 

 a lobe, which is broadly semicircular except for a prominent median 

 angulation; labrum large and semicircular, with sparse and feeble 

 scaly ground sculpture; outer segments of antennae wider than long; 

 with fine but scattered punctures and with traces of ground sculpture. 

 Pronotum one-fourth wider than long, rather strongly narrowed to 

 base, base two-thirds as wide as apex ; sides straight in front, arcuate
