Specimem examined. — I have seen 11 examples in the British 

 Museum (including the type of gowdeyi) ^ 14 in the collection of Dr. 

 Cameron (including the type of nigrocaeruleus) ^ 2 from the Museum 

 of Comparative Zoology, 66 in the United States National Museum 

 (including 4 in the Casey collection), and 12 collected by me in 1935-37. 



Remarks. — This species is rather variable in several characters. It 

 seems to be our only widespread all-black species of this genus, but it 

 lias been found in numbers only under carrion. 



Examination of the types of nigrocaeruleus and goiodeyi has shown 

 them to be the same as gagafes. This species has not been definitely 

 recorded from new specimens since its description. 



This species has been collected from dead-meat traps, from "crowns 

 of TiUandsia,^'' from beneath dung and fresh chips, from the rotting 

 "fruit" at the base of an imported palm, in rotten grapefruit, and from 

 under chips and rubbish on stumps.

 sinuately narrowed to rounded basal angles; discal series of five im-
