wing with an appendix and the first posterior cell narrowed 

 at opening, the fonrth and anal cell closed. The legs are 

 stout and hairy, more especially the hind tarsi and apex of 

 hind tibiae ; the curious prolongation of middle tibige is 

 short, armed with very stout short spines on outer border, 

 and on inner border with thick hairs. 



CoDULA, Macquart. 



Dipt. Exot. Suppl. 4, p. 374 (1849). 



This genus, formed by the author for C limbipennis from 

 New South Wales, is allied to his genus Brachyrrhopola, to 

 which his second species of Codula belongs, but it is at once 

 distinguished by the absence of the curved spine on fore 

 tibiae, the moustache is composed of fewer hairs and con- 

 fined to the oral opening, and the abdomen is stouter and 

 shorter. With Macquart^s second species and one placed 

 by Bigot in this genus transferred to Brachyrrhopola, only 

 Macquart's typical species and one nearly allied to it remain 

 in the genus.
