Bethylide. 
Pristocera subrufescens, sp. n. 
3. Niger; mandibulis, antennis dimidio basali, tegulis pedibusque 
brunneo-testaceis ; abdomine fusco-ferrugineo ; alis flavo-hyalinis, 
venis testaceis, stigmate fusco. 
Long. 5°5 mm, 
3. Head subrectangular, longer than broad, slightly 
rounded at the posterior angles, shining, coarsely but not 
closely punctured, without a frontal sulcus. Hyes separated 
from the hind margin of the head by a distance fully equal 
to their own length ; posterior ocelli near together, much 
nearer to each other than to the hind margin of the head. 
Scape rather strongly curved, second joint of the flagellum 
distinctly longer than the third or fourth, the first subglobose, 
about half as long as the second. Mandibles bidentate at the 
apex below, with a third tooth above forming a broad cutting- 
edge. Pronotum no longer than the mesonotum and scutellum 
combined, narrowed anteriorly, shining, coarsely but sparsely 
punctured; mesonotum sparsely punctured, the parapsidal 
furrows distinct ; the hind margin of the pronotum rather 
broadly depressed ; scutellum shining, sparsely punctured. 
Median segment a little*longer than broad, not margined, 
rounded at the apex, finely punctured-reticulate, with a low 
median carina from the base not reaching the apex and not 
continued on the posterior slope, the base of the segment 
coarsely reticulate; the sides of the segment very finely 
obliquely striated. Abdomen elongate-fusiform, almost 
smooth, with a few scattered punctures on the apical segments. 
Hind tarsal ungues (fig. 1, c) strongly curved, with one 
slender acute tooth at the middle of the inner margin, one 
strong bristle at the base, and two externally before the 
median tooth. Basal joint of the hind tarsus with a scopa of 
hairs beneath intermixed with stout bristles. Submedian 
cell a little longer than the median; first brachial cell ill- 
defined, not closed at the apex ; radius nearly three times as 
long as the basal nervure. 
Hab. Natal, Durban (F. Muir).
