segments with long whitish yellow hairs ; the black hairs along the 

 apical margins of the 3rd to the Gtli abdominal segments forming 

 fringes and tufts; wings dark fuscous with a purple effulgence, 

 head from above trans\erse, extended well behind the eyes, rounded 

 and closely punctured all over ; mandibles broad at apex with a 

 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 

 tiagellum 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 Petauke 

 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
