Var. evcmescens, nov., ? , resembles the type except in the 

 colour of the fasciae of segments 1-4, which are without any 

 tinge of green.

This species is a Nomia sens, str., and appears to be tlie 

 first species described from the mainland of Africa with green 

 tegiimentary fascia?, though this group [iridescens, chalyheata,

 species it differs in having the abdomen only finely punctate 

 and the wings subhyaline (not distinctly fuscous).

Bingham (Fauna Brit. Ind. i. p. 449) separates these two 

 species on the presence or absence of a clypeal carina. I 

 have examined the series of each species, and find this 

 character valueless. N. fuscipennis (type) has a distinct
