On the Genun Stizus, Latr. 



The following notes on the genus Stizus are tlie result of a 

 rearrangement of the material in the National Collection. 

 Something yet remains to be done in the diflicult trldens 

 group of the genus, but in the other groups the notes are 

 fairly complete on the material available. I follow IlaiuUirsch 

 in his definition of the genus, though I have no doubt that 

 it will eventually be subdivided. Ashmead's classification is 

 evidently based on an insufficient collection, and does not 

 provide for some of Handlirsch's groups. Small genera 

 would have to be formed for more than one of these to make 

 the classification complete, and I agree with Ilandlirsch that 

 it is better to postpone such action until larger collections 

 are available. i\Iost of the African material is from the 

 African Entomological Research C;ommittee.

 Stizus cyanescens, Rad. Ilorae soc. ent. Ross. xxi. p. 96 (1877). 



This species occurs in S.W. Persia and also as far east as 

 Karachi. 



Stizus cornheri, sp. n. 



cJ . Niger, iridescens ; mandibulis basi, labro, clypeo, fronie sub 

 antennis, scape snbtus, prouot-o postice angustissime, segmcntis 

 dorsalibus 1-G fascia angusta apicali, ventralibus 2-6 macula 

 transversa utrincjue, tibiis subtus tarsisque pallide flavis ; alls 

 hyaliuis, costa leviter iiifuscata, veuis nigris. 



Long. 10 mm. 



^. Mandibles with a tooth on tiie inner margin near the 

 apex ; clypeus nearly three times as broad as long ; eyes 

 strongly convergent towards the clypeus, at the base of which 

 they are separated by a distance nearly equal to the length 

 of the scape. Antennae inserted nearer to the eyes than to 

 the base of the clypeus, the apical joints of the same structure 

 as in S. tridens, the tenth joint of the flagellum with a spine 

 at the apex, the eleventh strongly curved and a little longer 

 than the tenth, the apical joint only lialf as long as the 

 eleventh and forming a curved spine. Posterior ocelli only 

 a little further from each other than from the eyes. Median
