198 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



Types. — Holotype, Oxford Universitj^, collected on April 25, 1938, 

 by C. B. Lewis and G. H. Thompson. 

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



Cayman Islands: Grand Cayman (Lewis, in Oxford University collection). 



Specimens examined. — I have seen only the holotype. 



Remarks. — This species is very similar to eggersi. It differs in the 

 very evident sculpture of the front of the head and the nature of the 

 abdominal punctures. 



The type was taken in a light-trap. 



29. OSORIUS WEBERI, new species 



Description. — Rufocastaneous, head somewhat picescent. Head 

 one-seventh narrower than pronotum; eyes a little prominent; cly- 

 peus evenly and rather deeply emarginate, the angles prominent; 

 labrum truncate, slightly emarginate above the declivity, smooth 

 except at sides ; outer segments of antennae scarcely as long as wide ; 

 without distinct punctures but with sparse irregular tubercles basally 

 and behind the antennal ridges, densely and rather coarsely aluta- 

 ceous. Pronotum, about one-seventh wider than long, moderately 

 narrowed to base with the sides feebly sinuate throughout ; apex one- 

 fourth wider than base; the hind angles moderately rounded; lateral 

 margins not abrupt but distinctly wider basally; disk with median 

 impunctate stripe irregularly outlined and somewhat elevated in 

 Lasal half; with rather large, usually elongate, but very shallow and 

 irregular punctures, more or less united along median band; with 

 ground sculpture feeble except inside punctures. Elytra about as 

 wide as pronotum, one-fifth longer than wide, widest just behind 

 middle but sides straight before and behind; surface very uneven, 

 without distinct punctures but with a few tubercles laterally; with 

 traces of ground sculpture on the coriaceous surface. Abdomen with 

 feeble ground sculpture and sparse rather indistinct large punctures. 

 Anterior face of front tibia with an indistinct series of setigerous 

 punctures. Length, 4 mm. 



Type locality. — Trinidad, 12 miles north of Arima. 



Types. — Holotype, Museum of Comparative Zoology, and one para- 

 type. United States National Museum (No. 52490), collected by N. A. 

 "VVeber on June 23, 1935. 



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



Trinidad: Arima (Weber, in M.C.Z. and U.S.N.M.). 



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



Remarks. — This species is readily distinguished from eggersi by 

 its shallow pronotal punctures, its larger size, and the more deeply 

 emarginate clypeus. 



I have received no record of its habits.
