highest at the base. Petiolar area distinct, triangular, the keels broad, uniting 

 at the apex into one ; areola wide, roundly narrowed at the base, slightly 

 narrowed towards the apex, it extends to shortly below the middle ; the keels 

 then bulge out slightly and run to the apex, this widened apical part being 

 shorter than the upper, which is weakly and sparsely striated, the lower, 

 strongly and closely transversely striated. The 2nd segment above is finely, 

 closely, the base of the 3rd more weakly striated. Genital valves broad, long, 

 largely projecting. 



May be known from the other species by the scutellum being keeled beyond 

 the base and by the large, distinctly defined petiolar area. 



This species also differs from the others in having distinct parapsidal furrows. 



Zaporus? argenteopilosus, sp. nov. 



Black, densely covered with longish silvery pubescence, the antennal scape 

 except for a line above, mandibles, except at apex, palpi, the 2nd and 3rd 

 abdominal segments at the sides, the others entirely and the legs except the 

 coxae and trochanters, rufous ; the 4 anterior legs of a paler colour ; tegular 

 yellowish ; wings hyaline, the stigma and nervures black. 9 . 



Length 9 mm. ; terebra 2 mm, 



Deesa. June. 



Head closely, somewhat strongly punctured, as is also the thorax ; the 

 pubescence on the base of scutellum and on the sides of metathorax longer 

 and denser than elsewhere. Scutellum prominent, roundly convex ; the post- 

 scutellum densely covered with silvery pubescence. Abdomen smooth, shining, 

 the 2nd segment faintly aciculated. Base of hind femora and tibias and apex 

 of tibiae black. 



The metanotum is distinctly areolated ; the areola large, longer than wide, 

 closed at base and apex ; the base transverse in the middle, with the sides 

 oblique ; the apex is roundly turned inwardly : there are 2 large lateral areas, 

 the apical the larger ; the apical slope is keeled round the edges ; spiracles 

 oval about twice longer than wide. Post-petiole distinctly dilated. Recurrent 

 nervure received distinctly beyond the transverse cubital which is longish ; the 

 transverse median nervure interstitial ; the apical nervures in hind wings 

 obsolete, the transverse median nervure unbroken. Claws with at least 3 longish 

 spines. Clypeus not separated from face ; its apex rounded. Mandibles large, 

 the upper tooth longer and sharper than the lower. Labrum projecting, broad. 

 Radial cellule long ; narrowed at base and apex, widely, indistinctly angled at 

 the transverse cubital nervure. Abdomen dilately laterally on the apical half. 



This may not be a Zaporus ; it comes nearest to that genus in the Foersterian- 

 A.shmeadian systems. 



Nototrachus flavo-orlitalis, sp. nov. 



Head and thorax rufous, the face, except in the centre above, the orbits 

 broadly all round, a line on the sides of mesonotum, dilated roundly, inwardly 

 at the base, scutellum, except the basal slope and more narrowly at the apex, a
