BRACUYCISTIS (BBACHYCISTIS) NIQRIFRONS. new species 



Male. — Shining brownish orange, frons and upper part of face 

 glossy black. 



Space between outer ocellus and eye less than that of ocellus; space 

 between antennal socket and eye about half as wide as socket; 

 mandibles without an angle near base; clypeus but little emarginate, 

 the raised part not sharp and but little more elevated in center. 

 Propodeum with dorsal part almost as long as wide, evenly and 

 broadly rounded, without a pronounced median sulcus, the edges 

 rounded off, posterior face and upper margins of sides with setiferous 

 punctures. First segment of abdomen twice as long as high, and 

 about 1.5 as long as its apical width. Two or three of the dorsal 

 hairs on hind tibia strong but not conspicuously so. Venation as 

 in irmequa Us. 



Length, 9-10 mm. 



Type and one paratype. — Graham Mountains, Ariz., Ash Creek, 

 3,200 feet, June 15, 1914 (E. G. Holt). 



Type and paratype.— C&t. No. 27921, U.S.N.M. 



BBACHYCISTIS (BRACHYaSTIS) INAEQIJAUS Fox 



This species has the hypopygium similar to that of atrata Blake. 

 The marginal cell of fore wing is as in figure 20. When the head is 

 viewed from the side the apex of the anterior elevation of the gular 

 carina is quite clearly visible below the level of the mandibular 

 condyle and almost in line with it. The clypeus is broadly and 

 evenly emarginate in center, the margin of the central part being 

 very little elevated and without a central tubercle ; the space between 

 eye and antennal socket is very narrow, that between eye and 

 posterior ocelli a little narrower than transverse diameter of the 

 ocellus. Propodeum broad, evenly rounded, and with rather coarse 

 setiferous punctures posteriorly, laterally. Basal segment of abdo- 

 men about 1.25 as long as its apical width. 



Length, 10-12 mm. 



Originally described from Los Angeles, Calif., from which locality 

 I have many specimens before me. I have also some from Texas. 



BBACHYCISTIS (BBACHYCISTIS) CURVATA, new species 



Male. — Differs from inaequalis as stated in key and as follows: 

 More slender; propodeum with a broad shallow sulcus on anterior 

 part of dorsum in center; first abdominal segment about 1.5 as long 

 as its apical width. 



Length, 10 mm. 



Holotype. — Arizona (C. F. Baker). Paratype, Fort Mohave, Ariz. 

 (Junius Henderson) . 



Type and paratype.— C&t. No. 27919, U.S.N.M.
