 apices of the anterior pair with a distinct dark band, the posterior 

 with the anterior angle clouded, lower margin of the 3rd submarginal 

 cell twice as long as the upper ; mesopleurae dull, not actually strigose 

 but with some shallow impressions, like elongate punctures, arranged 

 somewhat in lines ; mesosternum diagonally striate at the base, and 

 along its posterior margin, where it meets trie metathorax ; metapleurae 

 and sterna deeply striate ; propodeum glabrous, transversely, rugosely 

 and somewhat irregularly striate ; abdomen nearly dull, black, the 

 surface very finely aciculate, and somewhat remotely punctured, the 

 basal segment less strongly so than the others, 2nd segment with 

 two testaceous spots near the base, more or less united in the middle, 

 3rd and following segments more or less hairy, the hairs of a brownish 

 hue, those of the apical segment very dense ; each segment viewed

The females of this species vary somewhat in size, and in 

 the form of the 3rd sub-marginal cell, which is wider on its 

 upper margin in some than in others ; also in one of Mr. 

 Morice's specimens there is a small basal spot on each side 

 of the 3rd abdominal segment as in the $. 



This species is allied to bicolor, F., but differs in the 

 shorter, less cylindrical prothorax of the $ , and from the ? 

 associated with that species by Costa (Oss. at Genere 

 Salius, p. 4), by the strongly striate propodeum, and accord- 

 ing to the figure given by that author, the very different 

 coloration and the different neuration of the anterior 

 wings. In the $ from Le Tarf the abdomen is clothed with 

 a fine silvery sheeny pubescence, and has the pronotum 

 entirely black, but in other respects it resembles the type 

 form.
