C. occipitomaculata was described from one male from 
Kansas; I have not seen it, but it belongs in this group of the 
genus and was compared with C. nigrescens. The female, 
above described, is near to C. nigrescens, and, barring sexual 
characters, agrees fairly well with Packard’s description, 
however there is some doubt. A female specimen named 
C. occipitomaculata in the Cresson collection is very near to 
C. deserta; until the female of C. occtpitomaculata is surely 
known it is better to consider this form new. 
Cerceris gnara Cress. 
A pair from Lee County, Texas, (Birkmann). The pygidial 
area of the female is a little more than twice as long as broad, 
broadest near base, the sides nearly straight, and the tip not 
much narrowed and rounded. In the male this area is not 
quite twice as long as broad, with parallel sides and truncate 
tip; the hair-lobes are about once and a-half their breadth 
apart; the last joint of antenne is longer than the penultimate, 
curved and concave behind. 
Cerceris alaope n. sp. 
o Face, two spots on pronotum, tegulee, post-scutellum, two spots 
on basal segment of abdomen, a broad band, emarginate in front on 
second segment, and narrower bands on following segments,. pale 
yellow. Antenne black above, scape beneath yellow, flagellum fulvous 
beneath. Wings fumose, darker on tip, stigma dull yellowish. Legs 
pale yellow; front and mid femora, apical part of hind femora, and 
apical half of hind tibia, black; venter black, a few pale spots each 
side. Clypeus very slightly evenly convex, almost flat, not swollen 
above, lower margin truncate, upper edge slightly rounded, coarsely 
punctate; hair-lobes rather narrow, fully twice their breadth apart; 
second joint of flagellum much longer than the third, apical longer and 
narrower than the preceding, and somewhat curved; lateral ocelli 
about as near to eyes as to each other; enclosure very large, smooth, 
with a median groove and indistinctly striate on base; abdomen (includ- 
ing basal segment) much broader than in C. fasciola; pygidial area 
hardly twice as long as broad, truncate at tip, sides parallel, rather 
densely punctate, and very hairy; spines on hind tibia, seven or eight, 
evenly spaced. 
Length 10 mm. 
Q Similar to male; clypeal process black across tip; large spot each 
side on face, spot at base of mandibles, extreme base of mandibles, spot 
behind eyes, yellow; flagellum mostly fulvous, abdomen marked as in 
male, but the bands more narrow, and that on second segment is more 
deeply emarginate; all femora mostly black, but pale on tips; clypeal 
process erect, longer than broad; enclosure large, and mostly smooth as
