New Species of Sphecoidea £7 
basal half of posterior femora anteriorly, anterior and intermediate tibiae, 
and posterior tibiae anteriorly, all yellowish. Wings subhyaline, darker 
at the apex; stigma ferruginous. 
6. Unknown. 
Type, a female collected at Mitchell, Nebraska, July 21, 1916 
(C. E. Mickel). One paratype, Mitchell, Nebraska, July 20, 
1916. (C. E. Mickel). 
The paratype differs from the type as follows: no spots be- 
hind the ocelli; no spots on dorsal plate of mesepisterna; two 
spots on scutellum; spots on propodeum somewhat reduced; and 
scarcely any ferruginous on the abdomen. 
May be readily recognized by the ferruginous legs, maculations 
of propodeum and the form of the clypeal projection. 
Cerceris fugatrix sp. nov. 
6. Length 20 to 21 mm. Black, moderately punctured, with long, thin, 
cinereous pubescence. Clypeus broadly tridentate, somewhat flattened, 
with strong, well-separated punctures on the margins, but almost impunc- 
tate medially; hair lobes about twice their breadth apart; frons above the 
insertion of the antennae with large, strong, almost contiguous punctures; 
the area behind the ocelli and the genae with the punctures well separated ; 
a median impressed line on the frons running from the anterior ocellus 
almost to the interantennal carina; ocelli in a very low triangle; first joint 
of flagellum about one and one third times as long as the second, joints 
seven to ten somewhat thickened, the last joint curved and somewhat 
acuminate; mandibles except the tips, clypeus, supraclypeal area and inter- 
antennal carina, frons entirely at the sides up to a point about the length 
of the scape above the insertion of the antennae, scape beneath, and a 
small spot behind the eyes, all pale yellow; scape above, pedicel and fla- 
gellum (except joints seven to ten) ferruginous; joints seven to ten of 
flagellum more or less piceous.. Thorax strongly punctured; the punc- 
tures on the posterior and lateral faces of the propodeum especially strong 
and well separated; enclosure of propodeum longitudinally striate on the 
basal half and at the sides, with a very deep median impressed line; large 
lateral spots on pronotum (widely separated), tegulae, metanotum and 
large spot on postero-lateral angles of propodeum, all pale yellow. Abdo- 
men, with strong, well-separated punctures; pygidial area slightly wider at 
the tip than at the base, rounded at the tip, about one and two thirds times 
as wide as long; lateral apical spots on tergite one, wide apical bands on 
tergites two to six (somewhat narrowed medially), basal half of tergite 
seven, large lateral spots, joined on the apical margins, of sternites two 
to four, and small lateral spots on sternite five, all pale yellow. Anterior
