short diagonal grooves; with rather feeble transverse strigulae. 

 Abdomen with punctures rather obscured by irregular strigulae. 

 Male, eiglith sternite with a narrow triangular emargination scarcely 

 as wide as deep; eighth tergite quadridentate, the middle pair much 

 longer and not widely separated. Femnale^ eighth tergite with four 

 slender processes, the middle pair much longer. Length, 1 to 

 11/^ mm. 



Type locality. — St. Lucia, DuBoulay Estate, district of St. Remy, 

 3 miles southeast of Soufriere. 



Types. — Holotype, female, U.S.N.M. No. 52453, collected by me on 

 April 23, 1936. 



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



St. Lucia: (Blackwelder stations 220B, 220G). 

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



Specimens examined. — Besides the type I have seen one specimen 

 in the United States National Museum and one collected by me in 

 May 1936. 



Remarks. — This species can be distinguished by the combination of 

 characters given in the key. My second example from St. Lucia is 

 entirely testaceous but is otherwise similar to the type. The Trini- 

 dad example lacks the diagonal grooves of the elytra, but this does 

 not appear to be of great importance. 



My specimens were found in rotting grapefruit and among fer- 

 menting chips on a fresh stump.
