carina anteriorly from above the antennal fossa; vertex with two 

 feebly carinate ridges posteriorly. Pronotvmi a little more than one- 

 fifth wider than long, one-tenth wider than head; anterior angles 

 prominent; sides crenulate but nearly straight in apical two-thirds, 

 feebly cmarginate just before the posterior angles; apex one-tenth 

 wider than base which is abruptly set off from sides; with four 

 feeble longitudinal ridges, middle pair forked at anterior fourth, 

 submarginals joining margin at anterior angles; disk with vague 

 traces of longitudinal carinulae. Elytra three-tenths wider than 

 long and three-tenths wider than pronotum; sides nearly straight, 

 but posterior angles narrowly rounded; with four moderately 

 strongly carinate longitudinal ridges. Integuments with very dense 

 and rather fine ground sculpture, less distinct on abdomen. Length, 

 11/2 to 1% mm. 



Type locality. — Grenada (see "Remarks" below). 



Types. — One of two specimens in the British Museum. Neither 

 has been labeled type. One is from Black Forest Estate; the other 

 has no special locality recorded. 



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



Cuba: Cayamas (Schwarz, in U.S.N.M.), Mina Carlota, Trinidad Mountains 



(Mann, in U.S.N.M.). 

 Jamaica: Santa Cruz (Blackwelder station 421), Kingston (Blackwelder station 



378), Troy (Blackwelder station 400). 

 Hispaniola: IlAm (Cameron, 1913; Leng and Mutchler, 1917). 

 Puerto Rico: Mayaguez (Blackwelder station 358B). 

 Dominica: Long Ditton (A.M.N.H.). 

 St. Lucia: (Blackwelder station 220H). 

 St. Vincent: (British Museum). 



Grenada: (Cameron, 1913; Leng and Mutchler, 1917; British Museum). 

 Trinidad: Port of Spain (Blackwelder station 109B), Mayaro Bay (Weber, In 



M.C.Z.). 



Specimens examined. — I have seen 6 examples in tlie British Mu- 

 seum, 18 in the United States National Museum, 2 in the American 

 Museum of Natural History, 1 in the Museum of Comparative 

 Zoology, and 8 collected by me in 1935-37. 



Remarks. — In the original description Dr. Cameron cites this species 

 from "Grenada (H. H. Smith) ; Haiti. Type in the British Museum." 

 I found six exam.ples in the collection of that institution, but four 

 were from St. Vincent and none from Haiti. Grenada is therefore 

 the type locality, and a lectotype should be chosen from the two 

 examples. I did not see any specimens in Dr. Cameron's collection 

 but presume that he has the Haitian specimens there. 



The examples from St. Vincent seem to differ very slightly from 

 the cotypes in having the two median ridges of the pronotum not dis- 

 tinctly convergent near the middle. This seems to be a variable char- 

 acter. I find also considerable variation in the approach of tlie sub-
