542 Mr. Edward Saunders on 



much as inpollux Kohl; antennae rather short, with the basal joint com- 

 pressed laterally, but not so wide as in pollnx; 3rd and 4th joints 

 subequal, hardly twice as long as the 2nd and about double the 

 length of their basal width ; pronotum very flat, nearly as long as 

 mesonotum and propodeum to its brow ; propleurae concave, so as to 

 form a distinct carina at their juncture with the pronotum ; pilose 

 covering of the pronotum so close as entirely to hide its surface; 

 mesonotum and scutellum clothed as the pronotum; clothing of the 

 propodeum less dense and greyer in colour, wings rather short, narrow, 

 front wings densely clothed with rather unusually thick hairs, apex 

 beyond the submarginals darker, veins wide, 2 submarginal cells, 

 the 2nd subtriangular, its apical nervure and that of the 3rd dis- 

 coidal not fully denned ; posterior wings subhyaline, anterior coxas 

 very swollen, femora swollen, but not nearly to such an extent as in 

 pollux; tarsi short ; metatarsus rather swollen, longer than the next 

 3 joints together. Abdomen about as long as the thorax, clothed 

 with a brownish-grey pile, much as the propodeum, looking 

 browner or greyer according to the light; apical segment clothed 

 with a few semi-erect hairs. 

 Long. 7J m.m.

POMPILUS, Sp. (?). 



$ 1. Biskra, 4. vi. 98. F. D. M. A very fine 

 species allied to the above, but rather larger 

 and with red legs ; the abdomen banded with 

 glaucous pubescence ; the form of the base of 

 the antennae and the milky opalescent wings 

 are almost identical with those of breviscapus, 

 Mor., and galadopterus, Kohl. Mr. Morice 

 only met with a single male, both antennae of 

 which have lost their apical joints, so that I 

 have not thought well to describe it.
