gular carina with a prominent elevation near anterior extremity on 

 each side, which is deflexed to sides, plainly visible below condyle 

 when head is seen from side, and almost in line with condyle. Propo- 

 deum rather stout, with a sulcus in middle anteriorly, the posterior 

 and upper lateral parts with numerous setiferous punctures. First 

 abdominal segment at most 1.5 as long as its apical width. Marginal 

 cell of fore wing as in figure 24. 



Length, 7-9 mm. 



Holotype and 12 jjaratypes. — San Diego, Calif. (Ricksecker) .

BRACHYCISTIS (BRACHYCISTIS) VERTICALIS, new species 



Male. — Colored as intermedia. 



Space between posterior ocelli and eye not much over 1.5 as great 

 as width of either ocellus, and twice as wide as space between anterior 

 and posterior ocelli. Space between eye and antennal socket as 

 wide as socket; clypeus convex, centrally elevated in the form of a 

 rounded vertical carina, the edge narrowly beveled on emarginate 

 central portion, the submedian angles not prominent; mandibles 

 ^^'ithout an angle between inner tooth and base; gular carina quite 

 conspicuously and sharply elevated on each side at a little distance 

 behind the transverse line of the mandubilar condyles, the gular 

 orifice at its anterior margin hardly wider than the space between it 

 and either eye. Pronotum not depressed and abruptly declivous in 

 front, rather evenly rounded; mesopleura glossy, with large punc- 

 tures; propodeum short and stout, with a shallow dorsal sulcus, the 

 sides above and posterior surface rather coarsely punctured. First 

 abdominal segment not longer than its apical width. Hind tibia 

 with quite conspicuous dorsal bristles. Vein bounding costal margin 

 of marginal cell bent down close to stigma. Anterior cross-vein of 

 hind -^nng (R4) erect, not shorter than Rg

Male. — Head black, mandibles, antennae, and palpi, brownish 

 orange, clypeus darker. Thorax, abdomen, and legs brownish 

 orange, abdomen dark brown apically. Wings clear, veins yellow, 

 stigma brown. 



Frons when seen from side projecting above the upper level of 

 eye distinctly more than height of ocellus exclusive of latter; space 

 between antennal socket and eye a little greater than width of 

 socket; the latter without a noticeable thickening below, not tuber- 

 culatc; clypeus as in figure 33; mandible with a sharp ridge extending 

 from inner tooth to base, which is rather angularly produced near 

 haso; guJar carina elevated in line with condyle at base of mandible,
