ART. 3 WASPS OF SUBJ-^AMILY BEACHYCISTIINAE MALLOCH H 



2. Division between dorsal and hind surfaces of propodeum marked by a single 

 carina which is usually quite sharp; basal segment of abdomen nearly twice 



as long as its apical width carinata Fox. 



Division between dorsal and hind surfaces of propodeum marked by two or 

 more irregular series of transverse rugae; basal abdominal segment with 



its apical width fully two-thirds as great as its length 



subcarinata, new species. 



BRACHYCISTIS (BBACHYCISTIS) RUGOSA. new species 



Male. — Similar to carinata, but a little darker in color. Differs 

 structurally in the characters listed in the key and as follows : Anten- 

 nal sockets but little produced below, not sharply so; central beveled 

 emargination of clypeus broader centrally, narrower laterally, the 

 emargination deeper; anterior elevations of gular carina higher^ 

 visible when head is viewed directly from the side. 



Length, 12 mm. 



Bolotype. — Golconda, Nev. September, 1915 (J. R. Bunch). 



Type.—Q^ii. No. 27910, U.S.N.M. 



BRACHYCISTIS (BRACHYCISTIS) CARINATA For 



This species is more slender than rugosa. Hypopygium as in 

 figure 48. 



Length, 12-14 mm. 



Originally described from La JoUa, Calif., from which locality I 

 have seen a specimen in the United States National Museum. A 

 large series from San Diego in same collection. 



BRACHYCISTIS (BRACHYCISTIS) SUBCARINATA, new species 



Male. — Very similar to carinata, differing as stated in key and as 

 follows: Head almost as in rugosa: propodeum more nearly vertical 

 behind; color darker. 



Length, 12 mm. 



Holotype. —Higley, Ariz., June 18, 1917, at light (E. G. Holt). 



Paratype. — Arlington, Ariz., June 16, 1919, at light (A. Wetmore). 



Type.—Cs.i. No. 27911, U.S.N.M. 



BREVIS group 



Characters. — Only two submarginal cells in fore wing; propodeum 

 without a transverse carina; second abdominal sternite not carinate; 

 hind coxae slightly carinate on posteroventral edge except in texana. 



KEY TO SPECIES 



Carina of gular orifice elevated into a prominent angle less than midway 

 from hind to front margin (fig. 32) ; hind coxae rounded on posteroventral 

 edges; clypeus with a rounded vertical elevation apicad of which the surface 



slopes slightly, the apical margin emarginate and flattened 



texana, new species. 



Carina of gular orifice not elevated about middle; clypeus with a more or less 

 beakhke central eminence; hind coxae sharp, almost carinate on postero- 

 ventral edges 2.
