512 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.57. 



name and referred to the genus Xenoschesis Foerster. It has the 

 second and thu"d tergites piceous laterally, the face and clypeus 

 yellow, and front and middle coxae piceous in front, but is otherwise 

 very similar to the female. 



In the United States National Museum collection is a male from 

 the same locality and captured on the same date as the homotype, 

 which I believe to be an abnormally colored specimen of this species. 

 It has the front and middle legs, except posterior side of femora, 

 the hind coxae in front and their trochanters, the tegulae, face, 

 clypeus, and scape below yeUow; the hind coxae, and front and 

 middle femora, except as noted, and the hind femora are testaceous. 

 In structure it is exactly what the male of pettitii should be. 



COLEOCENTKUS MANNI Cushman. new species. 



Related to pettitii Cresson, from which, in addition to the key 

 characters, it differs principally as follows: 



Female. — Length, 15 mm.; antennae, 10 mm.; ovipositor, 10 mm 

 Face practically impunctate, polished; propodeum barely three-fourths 

 as long as combined height of propodeum and metapleurum, spiracle dis- 

 tant by its length from pleural carina (in pettitii it is distinctly closer to 

 the carina); first tergite fully half as wide at apex as long; nervulus 

 nearly perpendicular and nearly interstitial (in pettitii it is strongly 

 oblique and distinctly postfurcai); subdiscoideus but little below 

 middle of apex of second discoidal cell, 



Male. — Length, 13 mm.; antennae, 12 mm. Differs from female 

 in having face, clypeus, scape below, palpi, tegulae (at least 

 basally) yellow; legs generally paler, with front and middle 

 coxae in front at apex, all trochanters in front, front and 

 middle femora at apex and their tibiae in front yeUow, hind tibiae 

 and femora more contracting in color; second to fourth tergites 

 laterally and their sternites more or less reddish. In the venational 

 characters, except that of the areolet, the male shows gradation 

 toward pettitii. 



Type locality. — Orens Island, Washington. 



Other locality. — Blue Mountains, Washington. 



Type.—Csit. No. 22102, U.S.N.M. 



Described from one female and two males, the female captured 

 July 14-30, 1909, by W. M. Mann, and the males July 15, 1896, by 

 C. V. Piper. 



COLEOCENTKUS PULCHRIPENNIS Cushman, new species. 



Female. — Length, 22 mm,; antennae, 15 mm,; ovipositor, 17 mm. 



Differs from all the other North American species in its very 

 dark wings. 



Head subpolished, sparsely punctate, except on face where punc- 

 tation is rather dense, and lower posterior orbits, where it is impunc-
