﻿38 F. W. EDWAKDS — A SYNOPSIS OF THE SPECIES OF 



the head and thorax, the blue in some species being replaceable by whitish, 

 probably owing to fading after death. The thorax is short and rounded. The 

 claws of the male give another marked generic character, which will at once 

 distinguish Uranotaenia from all other Culicidae. On the front legs the claws 

 are small and equal in length, though the inner one is often broader than the outer ; 

 on the mid legs there is one small and one large claw, the large one falcate ; on 

 the hind legs both claws are small and equal. In the second volume of his 

 Monograph, Theobald gives figures which purport to be the claws of the front 

 legs of U. annulata (p. 251), U. mashonaensis (pp. 260, 261) and U. alba (p. 262). 

 In each case, as I have proved by examining the types, these figures portray not 

 the front but the middle claws of the male. Again, Theobald states (Mon. 

 Cul. IY, p. 535) that the fore ungues of U. geometrica are unequal ; this also is 

 incorrect. All the claws are simple in both sexes. The fore claws of the female 

 are sometimes (? always) like those of the male — one being broad, and it was on 

 account of this circumstance that Theobald introduced the genus Anisocheleomyia. 

 In all his three species (A. nivipes, A. alboannulata and A. leucoptera), each of 

 which was described as from one or two males, the types are in reality females.
