338 MR. R. E. TURNER ON THE [Feb. 15 



receiving the two recurrent nervures at one-fifth from the base 

 and one-fifth from the apex ; second abscissa of the radius three 

 times as long as the first, transverse median nervure interstitial 

 with the basal nervure ; cubitus of hind wing originating just 

 beyond the transverse median nervure. 



Black ; smooth and slightly shining ; a spot of dull and very 

 short greyish pubescence at the base of the first dorsal abdominal 

 segment and another at each of the apical angles ; the third and 

 fourth dorsal segments covered with coarse, close-lying, almost 

 scale-like hairs of an ochreous colour. Wings hyaline, fuscous 

 from the basal nervure to beyond the apex of the radial cell. 



Length 9 mm. 



Hab. Victoria (C. French). 



This species does not quite correspond with the characters given 

 by Ashmead for Planiceps, the fore femora being less swollen 

 and the antennae inserted a little higher. But, until the family 

 is revised as a whole, I do not consider it advisable to found 

 new genera. 



Pebinaspis exulans, sp. n. 



2 . Clypeus broadly rounded at the apex, much broader than 

 long, covering the mandibles. Eyes reaching the base of the 

 mandibles, their inner margins curved, convergent both towards 

 the clypeus and the vertex, separated on the vertex by a distance 

 exceeding the length of the three basal joints of the flagellum ; 

 posterior ocelli twice as far from each other as from the eyes. 

 Head much longer than broad, slightly convex, strongly concave 

 beneath ; the front slightly produced between the antennae, which 

 are inserted distinctly higher than the base of the eyes ; the second 

 and third joints of the flagellum of about equal length, each 

 about twice as long as the first. Pronotum nearly as long as the 

 mesonotum, depressed anteriorly, broader than long, the sides 

 nearly parallel. Median segment about one-third longer than 

 broad, the sides parallel, gently sloped towards the apex, the 

 apical margin very widely emarginate, the angles produced into 

 spines. Abdomen sessile, the two basal segments the broadest, 

 the second longer than the first ; second ventral segment without 

 a transverse groove. Posterior tibia? spined, anterior tarsi without 

 a comb, tarsal ungues bifid. Second abscissa of the radius as long 

 as the third, first recurrent nervure received before the middle of 

 the second cubital cell, second near the apex of the third cubital 

 cell ; transverse median nervure interstitial with the basal nervure ; 

 cubitus of hind wing originating beyond the transverse median 

 nervure. Minutely punctured, opaque. 



Black, with close cinereous pubescence, which is thickest on the 

 c'ypeus and pronotum and forms broad transverse bands on the 

 apical margins of the abdominal segments. Wings subhyaline, 

 nervures fuscous. Spines of the tibiae whitish. 



Length 9-10 mm.
