 of Oran): 21. iv. 1910. 



An exceedingly small and (to the naked eye) rather 

 duskily coloured species. I found it settling on stones at 

 the foot of a sort of cliff where the pretty little Masarid 

 wasp Quartinia major, Kohl, was abundant, and suspect 

 that it may be parasitical on that species. 



Chrysis sefrensis, Buyss. <§. 



This species was described by Vicomte R. du Buysson 

 in the Revue d'Entomologie, August 1900, from a single 

 $ taken by M. Abeille de Perrin at Ain-Sefra in Algeria 

 (Province of Oran). I believe that it has not been since 

 recorded, and that the $ is still unknown. 



I was so fortunate as to meet with both sexes at a much 

 more northern locality in the same province, viz. at Ham- 

 mam-bou-hadjar, in April 1910. M. du Buysson has 

 kindly compared the £ with his original type and satisfied 

 himself of their identity, and it is at his request that I here 

 record the hitherto unpublished $. 



It is exceedingly like the $, so that a complete descrip- 

 tion of it would be superfluous. But the genae are slightly 

 less developed, evidently shorter than the scape of the 

 antennae, their exterior outlines (frontal view) not quite so 

 parallel, though the convergence is exceedingly slight, and 

 their inferior angles not so sharply prominent. In colour 

 its only difference from the $, so far as I can see, is a slightly 

 greater prevalence of the red (or coppery) tints over the 

 green with which they are blended, especially in the head. 

 Thus the vertex, almost the whole face, and the second 

 joint of the antennae, are thoroughly cupreous in the <$, 

 while in the $ all these parts are more or less virescent. 

 The third antennal joint appears to me to be altogether 

 non-metallic, while in the $ it is green above like the second. 

 As usual in the Genus, the <$ 3rd abdominal segment is 

 shorter and more truncate at the apex than in the $, and, 

 perhaps for this reason, the four " teeth " appear shorter 

 in proportion to their breadth; especially the exterior 

 pair are evidently far more obtuse than in the $, and lie
