Specimens examined. — I have examined 18 examjDles in the British 

 Museum, 7 in Dr. Cameron's collection, 12 in the collection of Stuart 

 T. Danfortli, 3 in the collection of the Rio Piedras Experiment Sta- 

 tion, Puerto Rico, 7 in the United States National Museum, and 43 

 collected by me in 1935-37. 



Remarks. — This species is readil}' distinguished by its size and its 

 pale elytra. Examples from South America are not before me, but 

 I have very little doubt that the West Indian specimens are the 

 same. 



I have collected this species from dung, manure, and the decom- 

 posing refuse from a grapefruit cannery. The specimen taken by 

 Busck in Puerto Rico was from "under bark of bucare tree."
