52(S Mr. E. Saunders on irymcnopiera Aculeata: 
reddish in the middle. The antennae appear to be rather thicker 
and longer than in pyyklialis. Mesonotnm finely and very closely 
punctured, clothed with pale decunibent .scarcely conspicuous pube¬ 
scence which gives it in certain lights a greyish appearance. Anterior 
wings strongly tinged with smoky brown, posterior pair much 
clearer; tegulae testaceous. Propodeum very finely rugulose both 
above and at the sides, clothed with a fine and very short grey 
pubescence. Legs black with the exception of the tarsi which are 
more or less piceous ; front tarsi without any regular comb ; the 
spines of the metatarsi not longer than the middle of the joint itself. 
Abdomen dull, exceedingly finely punctured ; the first three segments 
red, the rest black. 
$ (1). A single 5 fi’om Bone agreeing in sculpture, colour of wings, 
etc., with the above, is closely allied to pygidialis, but has a slightly 
narrower dorsal valve ; its front tarsi have a comb of long dark 
curved spines, and the .sides of the propodeum have distinct striae 
.amongst the rugulosities. 
Long. 11 mm. 
Had this female occurred at Biskra with the males I 
should have had no doubt of its being the other sex of the 
same species; but coming as it does from Bone, a much 
more northern locality, I feel it is wise to suggest the 
possibility of its being distinct.
