tinctly punctate; with dense fine pubescence. Male, seventh sternite 

 strongly produced at middle, with two semicircular emarginations 

 separated by a broad triangular tooth and bounded laterally by acute 

 processes directed posteromedially ; eighth sternite with a deep 

 broadly rounded emargination. Female, with sternites unmodified. 

 Length, 21/4 to 2% mm. 



Tyj^e locality. — Grenada, Chantilly Estate. 



Types.— In the British Museum. (One specimen in the United 

 States National Museum, No. 50876, is designated cotype— or 

 paratype). 



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



Grenada: (Cameron, 1913; British Museum; U.S.N.M.). 

 Trinidad: Tunapuua (Weber, in M.C.Z.). 



Specimens examined. — I have seen 115 specimens in the British 

 Museum, 1 in the Museum of Comparative Zoology, and 7 in the 

 United States National Museum. The last were part of the original 

 series, received in exchange. 



Remarks. — I am unable to separate the females of this species from 

 those of chapini, but the male characters are very distinct from those 

 of any other of our species. It belongs in the subgenus Sciocharis 

 as herein defined. 



I find no record of its habits.
