New Species of Sphecoidea 3 
third, fourth, fifth and sixth abdominal tergites with lateral spines; 
| 
a 
pygidial area rather narrow, sides parallel, punctured; seventh abdominal 
sternite broadly, roundly and deeply emarginate, making the sternite 
appear bifid; first, second, third and fourth abdominal tergites with a 
white fascia posteriorly, interrupted medially; fifth, sixth and seventh 
abdominal segments entirely ferruginous. Legs entirely black, except an- 
terior tibiae and tarsi testaceous; a line at the tip of the intermediate 
femora and a minute spot at the base of the intermediate tibiae whitish. 
9. Unknown. 
Type, a male collected at Mitchell, Nebraska, July 21, 1916 
(C. E. Mickel). One male paratype collected at Mitchell, Ne- 
braska, July 21, 1916. 
Similar to cockerelli, but there is no median tubercle on the 
vertex and the occiput is punctate rather than striato-punctate. 
Easily identified by the three ferruginous, apical abdominal seg- 
ments and the white markings of the abdomen. 
The paratype lacks the white on the posterior lobes of pro- 
notum, femora and fourth abdominal tergite. 
Oxybelus pectorosus sp. nov. 
6. Length 7 to 8 mm. Head black, covered with appressed silvery 
pubescence; clypeus three-dentate; front and vertex with strong, rather 
sparse punctures; occiput approaching rugoso-punctate; distance between 
the posterior ocelli a little more than twice the distance between the lat- 
eral ocelli and the nearest eye margin; flagellum reddish on the greater 
part, blackish basally. Thorax -black, covered with sparse, silvery, ap- 
pressed pubescence; mesonotum with strong, rather sparse punctures in- 
terspersed with fine rugae; mesepisterna coarsely punctured; mesepi- 
sterna strongly produced at the lower, anterior margin forming a promi- 
nent projection; scutellum punctured, with a median longitudinal carina; 
squamae long, with the tips very acute; metanotal spine apparently trun- 
cate (tip of spine broken), broadest just before the tip; area beneath 
the spine obliquely rugose; posterior face of propodeum transversely ru- 
gose, with a large, triangular, shining fovea medially; metapleura trans- 
versely rugose; tegulae testaceous. Abdomen black, covered with sparse 
silvery pubescence; first abdominal tergite with a median longitudinal 
sulcus; abdominal segments without any traces of lateral spines, rather 
strongly punctured; first abdominal tergite with obscure whitish lateral 
spots on the posterior margin; abdominal tergites one, two and three 
silvery fasciate; posterior margin of the fourth, and the fifth, sixth and 
seventh abdominal segments ferruginous. Anterior tibiae and tarsi red-
