342 BULLETIN 18 2, UNITED STATES NATIONAL MUSEUM 



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

 Hispaniola: Haiti, La Visits (Darlington, in M.C.Z.). 



Specimeiis examjined. — I liaA^e seen only the unique type. 



Remarks. — Tliis species is very distinct by its even fine ground 

 sculpture. It is similar to jammcensis in the male characters except 

 that the lobe is broader and not tapering to the truncate apex. 



I have received no record of its habits except that it was taken at 

 a considerable altitude, probably under ground cover. 



8. BIOCRYPTA JAMAICENSIS, new species 



Description. — Rufocastaneous, forepart sometimes picescent. Head 

 with eyes small, separated from base by nearly four times their diame- 

 ter, by two times from apex; basal segment of antenna nearly three- 

 fifths as long as head, distinctly longer than distance between them ; 

 the antennal grooves feeble; very irregularly punctured, some punc- 

 tures fairly coarse, dense posteriorly but only a few isolated in front ; 

 without distinct ground sculpture but vaguely coriaceous, more 

 strongly in front. Pronotwm with irregular impunctate median band 

 marked by very irregular series of punctures; punctures much as on 

 head; without distinct ground sculpture but surface irregularly 

 coriaceous. Elytra shorter and scarcely wider than pronotum, nar- 

 rower than the abdomen, closely appressed; with punctures a little 

 coarser than on head but sometimes united irregularly and separated 

 by irregular convex intervals; without distinct ground sculpture. 

 Male^ without trace of fovea on fourth sternite; with a moderate 

 transversely oval fovea on fifth, and with a narrow triangular lobe 

 extending to apex of sixth sternite ; sixth and seventh without vesti- 

 ture along middle ; eighth with a small rounded triangular emargina- 

 lion, about as deep as wide. Female, fifth sternite with a subbasal 

 median smooth area rising to an abrupt semicircular posterior rim. 

 Length, 8 to 9 mm. 



Type locality. — Jamaica, main range of Blue Mountains at an 

 elevation of 5,000 to 7,000 feet. 



Types. — Holotype, male, and paratype, female, in the Museum of 

 Comparative Zoology; two paratypes, male, in the United States Na- 

 tional Museum (No. 52507) ; all collected between August 17 and 19, 

 1934, by Dr. P. J. Darlington. 



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



Jamaica: Blue Mountains (Darlington, in M.C.Z. and U.S.N.M.). 



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



Remarhs. — This is likewise a subterranean form in appearance. It 

 is readily distinguished by the characters in the key as well as by the 

 male characters. This is the only species so far taken on Jamaica
