Bethylidae. 



Pristocera subrufescens, sp. n. 



S ■ Niger ; mandibulis, antennis dimidio baaali, tegulis pedibusque 

 brunueo-testaceis ; abdomine fusco-ferrugineo ; alis flavo-hyalinis, 

 venis testaceis, stigmate fusco. 



Long. 5'o mm. 



c? . Head subrectangular, longer than broad, slightly 

 rounded at the posterior angles, shining, coarsely but not 

 closely punctured, without a frontal sulcus. Eyes 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 flagellara 

 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 scutellura 

 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 tlie 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 long-er than the median: first brachial cell ill- 

 defined, not closed at the apex ; radius nearly three times as 

 long as the basal nervure.
