from vertex, and separated from the feebly convex central clypeal area 

 only by two shallow foveae; clypeus not separated from transverse 

 ridge; sparsely, moderately coarsely punctate throughout and very 

 distinctly strigulose; gular sutures impressed, leaving gula conve-s. 

 Pronotum truncate before and behind, sides rounded; width to length 

 as 3 to 2 ; middle moderately impressed; lateral sulci coarse, extending 

 to middle of length; sparsely not finely punctate; densely and very 

 distinctly strigulose. Elytra with striae rather coarsely punctate, 

 intervals punctured as pronotum ; sixth stria complete, wide, coarsely 

 punctate, usually briefly double near humerus; a vague seventh stria 

 on deflexed portion, which is rather coarsely sculptured. Length, 

 31/^ to 41/^ mm. 



Type locality. — Brazil. 



Types. — Presumably in Zoologisches Universitat Museum, Breslau. 



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



Cuba: (Laporte, 1835). 



Dominica: (Blackwelder stations 237, 24GB). 



St. Lucia: ( Blaekwelder stations 220D, 220G, 220H, 226, 227, 231). 

 St. Vincent: (British Museum). 

 Grenada: (Blaekwelder station 132). 

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



South America: Brazil (Graveuhorst, ISOG; LePeletier and Serville, 1825; 

 Fauvel, 1865; Sharp, 1876; British Museum; U.S.N.M.). 



Specimens examined. — I have examined 33 examples in tlie British

 of Comparative Zoology, and 104 collected by me in 1935-37. 



Remarhs. — This species also appears to follow the cocoa cultiva- 

 tion. Besides from the decaying cocoa pods, I have tal^en this species 

 under dry dung and under fermenting chips on breadfruit tree 

 stumps.
