368 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



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



Cuba: Cayamas (Schwarz, In U.S.N.M.), Jatibanlco (Christenson, in ILS.N.M.), 



Limones (W. M. Mann, in U.S.N.M.), Soledatl (Weber, in M.C.Z.). 

 Jamaica: Blue Mountains (Darlington, in M.C.Z.). 



Speeiineiis examined. — I have seen four examples beside the types 

 in the United States National Museum, and two in the Museum of 

 Comparative Zoology. 



Remarks. — This species is normally one of the ones with maculate 

 elytra, but even in our eight specimens there is great variation, the 

 dark spot being almost completely absent in two cases and covering 

 the entire basal two-thirds in another. 



I have no record of the habits of this species except that the Soledad 

 example was collected in a Berlese funnel. 



3. ASTENUS JUVUS, new species 



Description. — Kufotestaceous, apex of abdomen feebly picescent. 

 Head about one-seventh longer than broad ; eyes at a little more than 

 their length from base; scarcely narrowed behind eyes, basal angles 

 moderately rounded; with very dense umbilicate punctures above ob- 

 scured by ground sculpture in front; supraantennal ridge clearly 

 u.niting with upper margin of eye ; beneath with rather coarse abrupt 

 l^unctures; ground sculpture visible in certain lights on all of the 

 ventral aspect; united gular sutures somewhat impressed near base. 

 Pronotum nearly one-fifth longer than wide, about as wide as head, 

 widest on anterior third, sides feebly arcuate and strongly converging 

 anteriorly, nearly straight and feebly converging posteriorly; with 

 dense umbilicate punctures; with indistinct ground sculpture on the 

 ridges. Elytra widest at middle, narrowed to both ends; with coarse 

 asperate punctation, moderately dense. Abdomen finely and moder- 

 ately sparsely, somewhat serially, submuricately punctate. Male., un- 

 known. Female., eighth sternite rounded. Length, 4 mm. 



Type locality. — Trinidad, Montserrat, in county of Caroni. 



Types. — Holotype, female, U.S.N.M. No. 52427, collected by August 

 Busck. 



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



Trinidad: Montserrat (Busck, in U.S.N.M.). 



Specimens examined. — I \\ix\Q seen only tlie unique type. 



Remarks. — Tliis species seems to be distinct from the true West 

 Indian species by the character of the supraantennal ridge. I am not 

 able to determine whether it is distinct from all the South American 

 species, however. 



I find no record of its habits.
