 black and red abdomen. 



Nomia grisella, sp. n. (muscosa, subsp. ?). 



5 . — Length about 9 mm. 



Black; very closely allied to N. muscosa, Ckll., differing 

 as follows: — Third joint of labial palpi longer; mesothorax 

 not so hairy, the dull, very finely punctured surface visible; 

 hind margins of second and following abdominal segments 

 light testaceous. Compared with N. yilberti, Ckll., it differs 

 by the strong keel down the middle of upper part of face ; 

 reduced metathoracic enclosure, and sides of metathorax 

 densely hairy right up to enclosure ; very dark fuscous hair 

 on inner side of hind basitarsi, &c. The abdomen is much 

 less distinctly and strongly punctured than in muscosa, 

 especially on the first segment. The second s.m. is narrow, 

 and the tongue is long and filiform.
