on the apex, whitish yellow ; the upper apical half of the femora 

 blackish. Wings hyaline, the apex slightly infuscated ; the costa and 

 stigma fulvous; the nervures blackish. Antennae rufous, darker 

 above ; the scape whitish yellow below ; they are as long as the 

 abdomen and half the thorax. <? . 



Length 14 mm. 



Face closely punctured, the centre raised ; its apex broadly 

 rounded, with a minute projection in the middle. Clypeus black, 

 punctured, its apex raised, transverse. Labrum white, as are also 

 the palpi and the basal half of the mandibles. Front and vei'tex 

 closely punctured ; below the ocelli is a triangular area formed by 

 two stout keels which converge below and are continued as one to 

 the antennae. The pubescence on the head is dense and white ; it is 

 longer on the temples. Thorax strongly and closely punctured ; the 

 scutellar keels are large, leaf-like, project largely on the sides at the 

 apex, the projection rounded and narrowed to a blunt point below. 

 On the base of the metanotum are two longitudinal keels, rounded 

 at the apex, forming a square area open at the apex ; outside this, at 

 the base, is a shining square area, irregularly wrinkled. There is a 

 broad furrow along the sides of the mesosternum, which is widened 

 and shining at the apex. Abdomen nearly twice the length of the 

 thorax ; it is slightly narrower than it ; the basal three segments are 

 more strongly and not quite so closely punctured as the others ; the 

 third is irregularly punctured-reticulated in the middle. Areolet 

 wide, shortly, but distinctly appendiculated ; the recurrent nei'vure 

 is received in the middle. 



Allied apparently closely to M. alhipectus, Tosq. 



Probably from near Cape Town. 



Metopius latibalteatus, sp. nov. 

 Black, the face, lower half of the upper inner orbits broadly, the 

 sides and apex of labrum, a spot on the inner side of the malar 

 space, palpi, a line on the pronotum, narrowed at the base and 

 apex, a mark at the sides of the scutellar depression, scutellums, a 

 large mark on the sides of the median segment, the tubercles, 

 almost the basal half of the mesopleurge ; the mark widened and 

 rounded below, the first abdominal segment except the basal slope 

 and the apical half of the others, lemon-yellow. Legs lemon-yellow, 

 the four anterior femora tinged with rufous above ; the hind coxae on 

 the inner side, the greater part of the femora on the inner side, the 

 black continued below and as a large oblique mark in the middle of 

 the outer ; the tibiae and tarsi rufous. Wings hyaline, the apex with
