The relationship of this species is with E. rufus, Be. ; the two may be 
separated thus : 
The hind orbits entirely yellow, the yellow line on the inner broad, dilated in the 
middle below, the basal horny point oblique, conical, longer than it is wide in 
front ; the hind ocelli separated from the eyes, metanotum without a transverse 
keel on the top of the striated part. rufus Be. 
The inner and outer orbits only narrowly yellow, the inner line not dilated below, 
the basal horny point triangular, not longer than wide, the hinder ocelli not 
separated from the eyes, metanotum with a distinct basal transverse keel. 
transvaalensis Cam. 
Pleuroneurophion rotundistriatus , sp. n. 
Rufo- testaceous ; the apical abdominal segments infuscated, the 
wings hyaline, the costa and stigma ferruginous, the nervures blackish, 
the transverse basal nervure and the basal abscissa of the radius lighter 
coloured, tinged with ferruginous ; the outer orbits tinged with yellow. 
Sides of scutellum stoutly keeled on basal half ; the apical slope finely, 
closely striated. The extreme base of metanotum smooth, the rest of the 
basal part finely, closely striated, more strongly laterally than in the middle ; 
the upper part of the apical slope transversely striated, the rest more 
strongly striated, the striae roundly curved, running into reticulations on 
the sides. Propleurae punctured, the punctures large and clearly separated 
above, finer and closer below, the centre more or less striated. Mesopleurae 
more strongly punctured all over ; the metapleurae much more strongly, 
obliquely punctured, the punctures almost forming striae. Face closely, 
the clypeus less closely punctured ; the labrum closely and strongly 
punctured. Hinder ocelli almost touching the eyes. The pubescence 
dense and white. First abdominal segment distinctly longer than the 
scutellum and metanotum united ; the apex nodose, fully twice wider 
than the base. Female. 
Length, 24 mm. 
Kourulene (Zoutpansberg District). December. 
The transverse cubital nervure in the hind wings is broken at the 
top of the posterior fourth, where it is sharply angled ; the two abscissae 
are straight and obliquely sloped. Temples half the length of the top of 
the eyes. Parapsidal furrows weakly indicated on the basal slope of the 
mesonotum. 
This species is smaller than P. pruinosus, Cam. ; the following are 
the chief differences between the two : — 
The hinder orbits entirely clear whitish yellow : the scutellar keels white, densely 
covered with white pubescence, the costa black, apex of metanotum reticulated, 
the transverse cubitus in hind wings broken at the top of the apical third, the 
fore part rounded. pruinosus Cam. 
The hinder orbits with the inner half obscure yellow, the scutellar keels ferruginous,, 
not densely haired, apex of metanotum roundly transversely striated : the 
transverse cubitus in hind wings broken at the posterior fourth, the fore part 
straight. transraalensis Cam.

Campoplex transvaalensis, sp. n.
