Adams — Eremoleon 
7 
Comparative Zoology. To the type has been affixed a 9 
abdomen from a specimen of another species. 
E . macer may be differentiated from cerverinus by its 
more slender labial palpi, and by its having a swelling, 
bearing a dense brush of setae, on the ventral side of the 
apical tarsomere. E. pallens has no distinct vertex mark- 
ings, has black setae on the pronotum, and four rows of 
cells in the cubital area of the hind wing. 
The character upon which Navas based his genus Belen, 
anastomosis of several prestigmatic cross veins, is present 
in the holotype, but not in the male. There being no other 
character of generic significance separating cerverinus 
from the other species of Eremoleon, Belen must be con- 
sidered a synonym of that genus. 
Eremoleon sectoralis, new species 
Figure 1 d, e 
Lower face and mouthparts pale, frons and vertex 
fuscous. Vertex scars brown-suffused; pattern like that 
of cerverinus (fig. la), but two lateral spots of second 
vertex row are fused. Scape shiny brown, pedicel brown 
above. Palpi (fig. le) slender. Thorax brown-fumose 
above, pale yellow below, no distinct macular pattern. 
Mesepimeral wing process honey-yellow. Legs pale, brown- 
dotted at setal bases; brown bands at apex of femur, near 
base and at apex of tibia, and at tip of last tarsomere. 
Fore tibial spurs equal 31/2 tarsomeres in length, hind 
spurs, 21/2 tarsomeres. Apical segment of fore tarsus 
cylindrical, length 0.37 times that of entire tarsus. Ab- 
domen brown-fuscous, without distinct markings; 2nd and 
base of 3rd sternite, and segments 7-10, pale. 
Setae mostly dark, except some pale on frons, clypeus, 
cervical sclerites, meso- and metapleurae, base of fore 
coxa, and 2nd and 3rd abdominal sternites. Pronotal 
setae shorter than those of cerverinus, and more numerous 
behind furrow. Setae on apex of 9th abdominal tergite, 
and posteroventral portion of 10th, short (less than 0.14 
mm. long), black, stout, decumbent; tips flattened, ex- 
panded, blunt. 
Wings (fig. Id). Basal costal veinlets widely spaced; 
cross veins absent from first few branches of Rs. Venation
