punctation than on pronotum, entirely dark. Body beneath dark 

 brown or piceous with legs pale yellow brown except hind femora, 

 which are brownish. Hind femora thickened, hind tibiae slightly 

 channelled, spur at end, first tarsal joint very long, claws appendicu- 

 late. Length 1.8-2.5 mm; width 1-1.2 mm. 



Type, male, USNM 66189, and 18 paratypes, collected on an 

 "unknown vine," at Matrullas, Puerto Rico, October 22, 1934, by 

 R. G. Oakley. 



Remarks. — H. S. Barber has labelled this "?Longitarsns sp." 

 with the fm'ther note that "this is probably a new genus and new 

 species." It does not resemble the usual species of Longitarsus: 

 first, in its coloring, which is dark piceous or black instead of brownish 

 or yellowish; second, in the shape of the elytra, which are considerably 

 wider than the prothorax and with well-developed humeri and basal 

 callosities and a transverse depression below them; and lastly, in the 

 shape of the aedeagus, which is different from any of the species of 

 Longitarsus that I have ever examined. On the other hand, the 

 channelled tibiae and the very long first tarsal joint of the hind legs 

 are typical of a species of Longitarsus, and for the present, until 

 similar species appear, it seems better to assign the present species 

 to this genus,

Two specimens collected at Aguirre, Puerto Rico, by H. E. Box in 

 May 1925, resemble a series from El Valle, Venezuela, taken by 

 C. H. Ballou September 4, 1939, on Heliotropum indicum, and a 

 series from Pichilingue, Ecuador, taken by E. J. Hambleton, October 

 15, 1944. Harold's description of Longitarsus suhtilis from Venezuela 

 appears to fit these beetles. He describes the species as a beetle with 

 a rufous head, a piceous thorax, and smooth rufotestaceous elytra, 

 having the apex and a wide median fascia more dilute at 

 the suture, rufopiceous, the feet testaceous, the posterior femora 

 rufous, the four basal antennal joints as testaceous, and the remainder 

 fuscous. Although there are minor differences, this description 

 appears to apply fairly well to the present species, which now is 

 found to occur in Puerto Rico.
