ART. 3 WASPS OF SUBFAMILY BRACHYCISTIINAE MALLOCH 17 



BRACHYCISTIS (BRACHYCISTIS) DENTATA Bradley 



Male. — -Head dark castaneous, almost black above; thorax and 

 abdomen brownish orange; stigma dark brown. 



Space between eye and posterior ocelli about equal to transvei-se 

 diameter of either ocellus and to space between posterior ocelli and 

 anterior ocellus; a slight transverse ridge above each antennal inser- 

 tion; space between edge and antennal socket almost linear; clypeus 

 with a rather beaklike tubercle on its lower margin in middle, beyond 

 which the edge is abruptly beveled, the submedian angles not notice- 

 ably toothlike; mandibles stout, the upper edge sharp and rather 

 conspicuously angled near base; gular carina much as in inaequalis. 

 Propodeum finely shagreened dorsally and with or without central 

 sulcus, the sides above and posterior surface with setiferous punc- 

 tures. First segment of abdomen fully as long as its apical width. 

 Hind tibial bristles not conspicuous, and sparse. 



Length, 8 mm. 



Locality. — Flagstaff, Santa Rita Mountains, and Fort Grant, 

 Ariz., Mesilla and Lordsbury, N. Mex.; Colorado, and San Ber- 

 nardino, Calif. 



Originally described from New Mexico. 



BRACHYCISTIS (BRACHYCISTIS) UTAHENSIS, new species 



Male. — Very similar to the preceding species, differing as stated 

 in the key. The sulcus on propodeum is more distinct than in the 

 last species the basal abdominal segment shorter, and the size greater. 



Length, 10 mm. 



Holotype.—Vtsih (C. F. Baker). 



Type.~Cat. No. 27920, U.S.N.M. 



BRACHYCISTIS (BRACHYCISTIS) ALCANOR Blake 



If my interpretation of this species is correct it varies considerably 

 in size, intensity of puncturation, size of ocelli, and some other 

 characters. It is possible, however, that a careful scrutiny of more 

 material from the various localities Usted below will prove that 

 there is more than one species in the lot now before me, which fact 

 I can not demonstrate satisfactorily at this time. 



Length, 7-15 mm. 



Originally described from .Arizona. Specimens in the collections 

 here are from Arizona, and Los Angeles County, Calif. 



MICROMMATA group 



Characters. — Distinguished by the small size of the ocelli, the 

 posterior pair being separated from the eyes by a (Ustance almost or 

 c^uite twice as great as the transverse diameter of one ocellus. 



I have not seen micrommata Bradley, but use the characters given 

 by Bradley for distinguishing it from the new species in the following 

 diagnosis.
