Types.— Either in the Hope Museum, Oxford, or the Zoologische

 welder station 86).

South America: Colombia (Erichson, 1840; Sharp, 1886; British Museum). 



Central America: Guatkmat^v (Sharp, 1886; British Museum), Panama (Sharp, 

 1886; British Museum; Bierig, in the Cameron collection). 



Specimens exambud. — I have examined 239 specimens from the West 

 Indies in the British Museum, 7 in the collection of Dr. Cameron, 1 in 

 the Museum of Comparative Zoology, 8 in the United States National 

 Museum, and 100 collected by me in 1935-37; also a few specimens 

 from Central America. 



Remarks. — The identification of these West Indian specimens with 

 the Colombian species has not been verified by me, although I have 

 examined the latter briefly without noting any differences. The 

 species is somewhat variable in color but can be separated by the 

 characters in the key. It belongs in the subgenus Siilocharis. 



I have collected it from dung, manure, and excrement, and from 

 rotten fruit, decaying cocoa pods, and fermenting cocoanut husks.
