ART. 3 WASPS OF SUBFAMILY BRACHYCISTIINAE MAIXOCII 21 



BRACHYCISTIS (BRACHYCISTIS) NITIDA (Cresson) 



This is a rather (hstinct species, distinguished from its aUies by the 

 narrow gular orifice, and elongated first abdominal segment. The 

 space between eye and posterior ocelli is distinctly narrower than 

 the transverse diameter of either ocellus, the head is yellow, forehead 

 with sparse minute punctures; space between eye and antennal socket 

 about as wide as socket; cl3'peus bevelled in the space between edge 

 and central elevation, the submedian angles prominent but not 

 toothed; gular carina erect to anterior extremities; mandibles stout, 

 curved, sharp edged above on apical half but without a noticeable 

 angle basally. Propodeum rather elongate, rounded above, and with 

 a more or less evident central sulcus. Hind tibia with r^uite pro- 

 nounced dorsal bristles, which are set on slightly elevated bases. 

 Marginal cell as in inaequalis Fox. 



Length, 11-14 mm. 



There is a paratype from Colorado in the United States National 

 Museum. 



Paratype. — Cut. No. 1667. U.S.N.M. 



In addition to this I have before me specimens from Colorado, 

 New Mexico, and Lincoln, Nebr. Bradley records it also from Ari- 

 zona. 



BRACHYCISTIS (BRACHYCISTIS) WASHINGTONA, new species 



Male. — Brownish-orange, upjier half of head, tips of mandibles, 

 and stigma blackish. 



Posterior ocelli about l.o as wide as space between either and eye, 

 the distance between anterior and posterior ocelh a little over half as 

 wide as that between posterior ocelli and eye: usually two or four 

 elevated points above antennal insertions; clypeus with a rounded 

 central emargination above the middle of the beveled edge of which 

 there is a small raised point, the rim on which it is situated quite 

 rounded; gular carina slightly flared to side anteriorly, widely sepa- 

 rated from cond3de. Propodeum stout, with setiferous punctures on 

 posterior side and on upper part ol sides. Basal segment of abdomen 

 about two-thirds as wide at apex as long on sides. Marginal cell 

 similar to that of inaequalis Fox. Hind tibia with or without one or 

 two dorsal bristles. 



Length, 12-13 mm. 



Bolotype and three paratypes. — Ritzville, Wash., August, 1920 

 (R. C. Shannon). 



Type and paratypes. — Cat. No. 27926, LT.S.N.M. 



BRACHYCISTIS (BRACHYCISTIS) NEVADENSIS Fox 



A specimen which runs to this species in Bradley's key is very 

 difficult to distinguish from those I consider are glabrella Cresson. 

 In fact the only character upon which it is separable, the comjiarative
