Nomia iridescens, Smith. 



Singapore (H. N. Ridley). British Museum. 



The abdominal bands are brilliant blue-green, shot with 

 purple ; the first five segments are banded in the male. The 

 thorax above has a good deal of fuscous hair in both sexes ; 

 this is not indicated in Bingham's description (Hymenop. 

 Brit. India), but there is no doubt about the identity of my 

 insect, as I possess a cotype from F. Smith's collection. 

 The tegulaa are pointed or caudate posteriorly. 



Nomia iridescens, var. ridleyi, nov. 



$ . — Structure exactly as in N. trtdescens, but the five 

 abdominal bands yellow-green shot with orange-vermilion ;

 Museum. 



Nearest to N. (Crocisaspidia) forhesii (W. F. Kirby) from 

 Socotra, and N. lamellata } Smith, from Egypt, but distin- 

 guished by the prevailingly red coloration. 



Nomia (Crocisaspidia) lamellata, Smith, 1875. 



The type male, from Egypt, was examined and found 

 to have the Crocisaspidia scutellum and postscutellum.
