Colpocephaluni sj(este(lti n. sp. 



(I'l. 7, tig. 7.) 



Several females from Corvus scapuhtits and Corvultur albicollis. An extraordi- 

 nary form of Colpocephalma of the general type of Carriker's curious and abberant 

 C. extraneum , taken from a night-jar, Nyctidromus albicollis, Costa Rica. These two 

 species are strangely widely separated both in host relation and geographically and 

 yet they agree so closely in the characteristic, namely, the extraordinary extension 

 of the metathoracic dorsum and its curious shape, tliat separates tliem froni all other 

 species of the genus that they should probably be set apart in a distinct genus. For 

 the present, however, we may let them stand in Colpocephalum. The African spe- 

 cimens from the crows differ from the Single Costa Rican female from the night-jar 

 in the presence of pustulations on the temples, an all brown metathorax, and the 

 median abdominal blotches; the metathorax is also truncate or even emarginate on 

 the abdomen. 



Female, length 2.2ö m.m., width 0,« m.m., large for, Colpocephalum, strongly 

 marked and characterized by the great posterior extension of the dorsum of the 

 metathorax, with its deep angular median emargination. Head, length {).5i mm., 

 width 0.78 m.m; temples strongly projecting and rounded with fonr long pustulated 

 hairs and other shorter ones; well marked fringe of short curved hairs on lateral 

 margin behind eye; head pale translucent brown with strong large triangulär ocular 

 blotches and narrow black temporal and occipital border. Prothorax hexagonal with 

 produced lateral angles furnished with Single spine. Mesothorax distinct from meta-
