4 J I: Mr. G. Meade-WiiKlo on 



witli basal segment of a paler testaceous than tlie apical 

 segment. Posterior tibiiB and metatarsi of equal length, 

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

 finely and evenly punctured, the legs coarsely punctured. 



Wings subhyaliue, slightly smoky. 



Length 15 mm. 



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

 2uon), 1 ? . 



This fine species is easily recognized by the swollen 

 tuberculate gense. -

Some corrections are necessary iu the synonymy of this 

 genus and its subgenera, owing to the wrong species having 

 l)een selected as type. The traditional view was tiiat 

 i\\ diversipes, Latr., was the type, whereas the true type is 

 i\^. curvipes (Fabr.), as selected by Bingham (' L'auna Brit. 

 Lidia,' i. p. 447) Asbmead (1699) and Cockerell (1910) 

 botii adopted N. diver sipes as tyj^e. 



I am inclined to follow Cockerell in regarding Nomia as a 

 single genus including several named subgenera. Para- 

 nomia, 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 

 wliich 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."
