1912] Eastern Species of Cerceris 
bo 
On 
Cerceris kennicotti Cress. 
This is a very common species in northern Virginia, and also 
occurs in Texas. The pygidial area of the female is about twice 
as long as broad at base. and fully twice as broad near base as 
at the truncate tip. The male has the hair-lobes fully three 
times their breadth apart; the pygidial area is hardly twice as 
long as broad, with curved sides, the tip almost one-half nar- 
rower than base. 
Cerceris compar Cress. 
From Ithaca, N. Y., and Falls Church, Va., The pygidial 
area of female is two and a-half times longer than broad, broad- 
est at middle, and much narrower at base than at tip. The 
male has hair-lobes so large that they are less than their breadth 
apart; the pygidial area is not twice as long as broad, and more 
narrow at base than at tip, its surface very coarsely pitted 
except near tip. The spines on mesosternum easily separate 
the male. 
Cerceris catawba n. sp. 
2 Black, face and clypeus pale yellow, on the sides extending above 
antenne and a line between them; antennz yellowish or reddish beneath, 
dark above, an elongate spot each side on pronotum, the scutellum, a 
stripe each side on metanotum pale yellow; all segments of abdomen 
with complete posterior yellow bands, that on the first segment as wide 
as that on second, but the latter concave in front; legs yellowish, the 
femora black on basal half or two-thirds, the hind tibize black at tip, 
the mid tibize with dark streak behind, the hind tarsi dusky, the basal 
joint only at tip. Wings smoky, darker in marginal cell and beyond, 
the stigma brown. Clypeus of female not elevated, produced below in 
middle, but truncate at tip, above broadly truncate; enclosure smooth 
in middle punctate on sides, pygidial area two and one-half times as 
long as broad, nearly as broad at apex as in middle, but narrowed at 
base. 
o Similar to female; with clypeus slightly convex, sparsely, 
coarsely punctate, lower margin slightly rounded but with a black, 
truncate edge; hair-lobes broad, but about their breadth apart; antennz 
high above clypeus, second joint of flagellum short, barely longer than 
the third, apical joint thick, but a little longer than the preceding; 
pygidial area twice as broad as long, sides subparallel, tip truncate, 
surface with a few coarse punctures; last ventral broadly emarginate at 
tip. 
Length 9 mm.
