Hymenoptera aculeata collected in Algeria. 561 



tubercle above the coxse ; wings dark brown-black with violet reflec- 

 tions, marginal cell very long, about three times as long as wide, 

 diagonally truncate at the apex, 3rd submarginal once and a half as long 

 as high • metanotum strongly strigose transversely ; propodeum with its 

 upper area nearly square, rugosely striate, pilose, subtectiform, the 

 centre being gradually raised into a central ridge, the apex truncate, 

 the lateral angles slightly prominent ; abdomen elongate, elliptic, dull, 

 5th ventral segment very slightly emarginate at the apex, 6th with a 

 strong carina on each side,8th semi-circu!ar ; legs,coxse and trochanters, 

 the base of the intermediate femora, and nearly the whole of the 

 posterior femora and tibiae as well as the tarsi black. 



$ Very like the £ in coloration, but with the red colour of the 

 thorax and head brighter and more extensive, the whole of the upper 

 surface of the thorax being red, its underside and propodeum black ; 

 cheeks behind the eyes with long black whiskers, 3rd joint of 

 antennas once and a half as long as the 4th, pronotum angulately 

 emarginate posteriorly, mesonotum very finely, closely punctured, 

 mesopleurse spinose as in the $ and the wings similar in colour and 

 neuration to those of that sex ; propodeum tectiform, pilose and trans- 

 versely wrinkled, truncate posteriorly, but with the lateral angles 

 rounded, not angulated as in the £ . The lower angles of the pro- 

 podeum are strongly developed in both sexes ; abdomen rather shin- 

 ing, very finely shagreened with a remote, rather large, but shallow 

 puncturation, apical segment clothed with black-brown bristles. Legs 

 coloured as in the £ . 



Long. 14-15 m.m. 



A very distinct species in coloration and in the form)!

The males taken by Mr. Morice all resemble those we 

 take in Britain, but the females have a distinct, clear, eye- 

 like spot near the apex of the wing, which is not the usual 

 form with us ; also the puncturation of the surface is coarser 

 and much more distinct, and the propodeum is transversely 

 striate towards the apex. I thought at first they were 

 referable to Morawitz's punctatissinvus, but he says of that
