546 Col. C. T. Bingham on South African 
segments with long whitish yellow hairs ; the black hairs along the 
apical margins of the 8rd to the 6th abdominal segments forming 
fringes and tufts; wings dark fuscous with a purple effulgence, 
head from above transverse, extended well behind the eyes, rounded 
and closely punctured all over; mandibles broad at apex witha 
preapical inner tooth and a blunt tooth near the base on the outer 
edge. Clypeus smooth shining excavate, a strong carina between the 
bases of the antennae, eyes somewhat prominent, convex, the lower 
orbit closer to the base of the mandible than the upper orbit to the 
lateral posterior edge of the occiput, antennae slender, 2nd joint of the 
flagellum shorter than the 3rd, which is very slightly longer than the 
4th. Thorax elongate oval, pro- and mesonotum and the pleurae, 
the scutellum and postscutellum coarsely punctured cribrate, tegulae 
of the wings small and smooth, median segment rounded reticulate, 
legs slender, punctured, intermediate and posterior tibiae with single 
rows of strong spines, basal joint of the posterior tarsi flattened, 
triangular; wings ample, forewing with three cubital cells. Abdo- 
men elongate, basal segment very long, petiolate, nodose at apex ; 
ventral carina simple not much raised extending about half the 
length of the segment from base, beyond it near the apical margin 
of segment there are two hollows or pits bounded and divided by 
slender short carina.

I have provisionally placed a single ? from Petauké 
under 0. angulata with much doubt. It is very much 
larger, more massive, looking at first sight very like a 
Barymutilla, but the head is not nearly so broad as the. 
thorax in front, and the median segment is angulated 
posteriorly. In sculpture and markings it is practically
