punctures; metanotum closely striato-granular ; dorsal aspect of the 

 propodeum irregularly transversely reticulate with striae especially 

 prominent in the median area ; the base with a short, sharply defined 

 median keel ; dorsal middle with a circular fovea which is surrounded 

 by two rings of striation ; posterior face oblique with a deep median 

 furrow which is broader posteriorly and transversely striate, dorsally 

 the striae are somewhat oblique tending to meet at the top of the 

 median furrow; sides of the propodeum finely granular, dorsally 

 with a tendency to an oblique aciculation; mesepisternum opaque, 

 finely granular; legs rather feebly spined, the longer calcaria of the 

 posterior tibiae about one-sixth shorter than the posterior basitarsus; 

 third cubital cell on the radius distinctly longer than the second; 

 pygidium sharply defined, about two and one-half times as long as 

 its basal width, with sparse, well-defined punctures apically with a 

 few coarse hairs, the apical margin truncate, angles rounded. Black, 

 the first and second tergites obscurely rufous; wings dark brownish, 

 venation dark brown ; body almost' without pubescence. 



Type-localitij. — Riverton, New Jersey. Described from one fe- 

 male collected September 22, 1907, by C. T. Greene, for whom the 

 species is named. 



Type.— Cat No. 18996, U.S.N.M. 



It is not unlikely that other specimens of this species will have the 

 abdomen entirely black or that some of them will have the first two 

 segments rufous. 



XYLOCELIA BEULAHENSIS. new species. 



Close to nigritus (Fox) but may be distinguished from that species 

 by the finer sculptured head and by the yellow spot on the tubercles. 



Female. — Length 5.25 mm. Clypeus polished, mth a few setiger- 

 ous punctures; the apical margin with three large teeth, the part 

 between the lateral teeth somewhat depressed; supraclypeal area 

 polished; front reticulate and with rather close, well defined, dis- 

 tinct punctures in addition; vertex and posterior orbits reticulate 

 but much more sparsely punctured than the front; ocelli in a low 

 triangle, the postocellar line slightly shorter than the ocellocular 

 line; third antemial joint a very little longer than the fourth; mesos- 

 cutum very finely granular, the anterior part with distinct, rather 

 close, well-defined punctures in addition; scutellum shining, nearly 

 impunctate; dorsal aspect of propodeum reticulate, posterior aspect 

 shining, almost without sculpture, a rather large punctiform fovea 

 at dorsal middle of posterior aspect from which a carina extends to 

 abdominal fossa; sides of propodeum shining, almost without sculp- 

 ture; pygidium rather well defined, one and one-fourth times as 

 long as basal width, granular, with a few irregidar punctures basally. 

 Black; posterior half of tubercles yellow; wings hyaline, iridescent, 

 venation dark brown, stigma black.
