338 BULLETIN 182, UNITED STATES NATIONAL MUSEUM 



Guadeloupe: (Hornhauer and Schubert, 1912; Leng and Mutchler, 1914). 

 Grenada: (Bernhauer and Schubert, 1912; Leng and Mutchler, 1914; British 



Museum). 

 South America: Colombia, Venezuela, Ecuador (Bernhauer and Schubert, 



1912). 



Specimens examined. — I have seen 13 examples in the British 

 Museum, two collected by Dr. Harold E. Box, tluee from the Museum 

 of Comparative Zoology, and two collected by me on October 12, 1935. 



Remarks. — This species differs from the genotype in the following 

 particulars (among others) : Much more distinct punctures on head 

 and elytra and much less distinct ground sculpture, shorter basal 

 segment of antennae, coarser punctation of pronotum, and the much 

 larger fovea of the fifth sternite of the male and the smaller emar- 

 gination of the eighth. 



There is at least some doubt of the South American records. I have 

 seen specimens only from Puerto Rico, Antigua, and (xrenada and 

 have no direct evidence that it is as widespread a species as is indicated 

 in the Junk Catalog. 



My specimens were taken while sifting leaves in a damp gully. 



3. BIOCRYPTA TRINITATIS, new species 



Description. — Rufopiceous. Head with eyes separated from base 

 by about twice their length; basal segment of antennae about two- 

 thirds as long as head, as long as distance between them; antennal 

 grooves distintt; with punctures of various sizes rather sparse; with 

 ground sculpture only at base and apex. Pronotum with median 

 smooth area not elevated but set off by fairly regular series of m.od- 

 erate punctures; sparsely and only moderately coarsely punctate; 

 without ground sculpture. Elytra larger than pronotum; with dense 

 moderately coarse punctures separated by flattened intervals, not at 

 all serial; without distinct ground sculpture. Male, unknown. 

 Female, all sternites unmodified except for fifth which has a central 

 smooth area rising to an abrupt semicircular posterior rim. Length, 

 8 mm. 



Type locality. — Trinidad, St. Augustine. 



Types. — Holotype, female, in Museum of Comparative Zoology, col- 

 lected in April 1929 by Dr. P. J. Darlington. 



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



Trinidad: St. Augustine (Darlington, in M.C.Z.). 



JSpecIme?is examined. — I have seen oidy the unique type. 



Remarks. — This specimen had been confused with ftdvlpes but 

 seems to be very distinct by the sparse punctation. Even an isolated 

 female seems worthy of description in this genus, of which only one 

 species is so far known from South America (Argentina). 



I have received no record of the habits of this species.
