454 Mr. G. Meade- Waldo on 



with basal segment of a paler testaceous than the apical 

 segment. Posterior tibiai and metatarsi of equal length, 

 hind calcar with four spines. Head, thorax, and abdomen 

 finely and evenly punctured, the legs coarsely punctured. 



Wings subhyaline, slightly smoky. 



Length 15 mm. 



Panama: Bugaba (Godman-Salvin Coll., G. C. Cham- 

 pion), 1 ? . 



This fine species is easily recognized by the swollen 

 tuberculate gente. 



NOMIA, Latr. 



Some corrections are necessary in the synonymy of this 

 genus and its subgenera, owing to the wrong species having 

 been selected as type. Tlie traditional view was tliat 

 N. diversipes, Latr., was the type, whereas the true type is 

 N. curvipes (Fabr.), as selected by Bingham (' Fauna Brit. 

 India/ i. p. 447) Ashmead (1899) and Cockerell (1910) 

 both adopted iV. diversipes as type. 



I am inclined to follow Cockerell in regarding Nomia as a 

 single genus including several named subgenera. Para- 

 no)7iia, Friese, would contain N. curvipes, the type of the 

 genus, and thus becomes Nomia, sens. str.

I have made a key to the Ethiopian species of Nomia of 

 which the types are in the British Museum. Of some species 

 there are large series, and in these cases several localities 

 have been given as an aid to distribution, the type-locality 

 being followed by a " t."
