Brachycistis iBrachycistisj brevis Fox, d'. 
Genitalia: Sagitta reduced to a short truncate lamella; volsella a small 
chitinous lobe; ramus short and broad, its upper hind angle acute, its inner 
side with a patch of setae; squama acute, with an entire margin; uncus rather 
long and slender, gradually widened to and truncate at the apex, somewhat 
deflexed (figures 34 and 38). 
The description and figures of the genitalia are drawn from a 
specimen in the collection of Cornell University, that has been 
found, on comparison, to agree with the type. 
California: [Type, American Entomological Society]; Calexico, August 
11, 1914, 6cf, [Cornell University]. 
Brachycistis (Brachycistis) eremi new species 
cf . Brownish orange; the mouth parts, antennae and legs yellow; a spot 
between the ocelli black; sparsely clothed with yellowish pubescence; wings 
hyaline, the veins pale, washed with brownish yellow, the stigma and Sc + R+ 
M brown. Length, 9 mm.; slender. 
Head jiolished, with a few small punctures; ocelli large, prominent, without 
an impressed line behind or between them, their measurements: .25 mm., 
.23mm., .3m. ; forehead with a transverse row of four tooth-like tubercles above 
the antennae; inferior margin of each antennal socket thickened and with a 
tubercle projecting dovniward; clypeus raised toward a premarginal median 
point, which as seen from the side appears as a prominent tubercle, from this 
abruptty declivous to the scarcely concave edge; teeth of the mandible in the 
type much worn, in paratypes the inner two are of equal size, acute, a carina 
extending from the inner one about half-way toward the base of the mandible; 
gular orifice small, its margin distant from the eye by considerably more than 
the length of the last segment of the labial palpus, and from the globular swell- 
ing at the condyle of the mandible by more than its width. Antennae crenu- 
late toward their apices. 
Pronotiun with humeral angles not prominent, its entire surface rather 
sparsely punctured; mesonotum polished and shining, bearing a few scattered 
punctures and deeply impressed lateral grooves; scutellum with a few scat- 
tered punctures on its disc, its sides closely finely punctured; postscutellum 
with disc impunctate, the sides closely, finely punctured; mesopleura evenly 
but coarselj' punctured, more sparsely toward the sternum, the surface prom- 
inently but not irregularly swollen, with a low tubercle near the upper part of 
the posterior margin of each; dorsal surface of the propodeum not punctured, 
except its sides, with a median area separated on either side by a carina, dorsal 
and posterior surfaces not separated by a transverse carina, the lateral angles 
rounded, not prominent, and no distinct line of separation between the dorsal, 
posterior and lateral faces; lateral angles coarsely but not rugosely punctured, 
the punctures extending forward along the upper part of the lateral surface 
and sides of the dorsal surface; the posterior face strong!}' declivous, with a few 
erect hairs and inconspicuous “spatter-punctures.”
