New Species of Sphecoidea 23 
without a projection having a free apical edge, the median basal portion 
very convex, almost forming a cone, and apical margin with two large 
very blunt teeth; frons strongly and closely punctate, with a raised line 
running from the interantennal carina to the anterior ocellus; ocelli in a 
low triangle; first joint of flagellum about one and one half times as long 
as the second; large spot on median basal portion of clypeus, small spot 
on supraclypeal area, broad lateral marks on frons extending up a little 
beyond the insertion of the antennae, scape beneath, minute dot on raised 
line of frons, and spot behind the eyes, all yellow; flagellum reddish 
above, yellowish beneath. Thorax with large, close punctures throughout; 
mesepisterna produced below forming a blunt tooth; propodeal enclosure 
coarsely, transversely striate (tending to obliquely striate at the base) ; 
large lateral spots on pronotum, tegulae, major portion of dorsal plate 
of mesepisterna, two large spots on scutellum, metanotum, and large, elon- 
gate spots on postero-lateral angles of propodeum, all yellow. Abdomen 
with large dense punctures; pygidium pyriform, about four times as long 
as it is wide at the base, about as wide at the tip as at the base, subtrun- 
cate apically, slightly transversely rugose; apical band on first’ tergite, 
broad band very deeply emarginate on tergite two, bands on tergites three 
and four much narrowed medially and broadened at the sides to cover 
the whole tergite, and apical band on tergite five, all yellow. Anterior 
femora flattened, excavated behind; anterior tibiae somewhat flattened; 
legs black; apical half of anterior femora, apices of intermediate and 
posterior femora, anterior and intermediate tibiae except a spot behind, 
posterior tibiae except the apices, all yellow; all the tarsi more or less 
reddish, the posterior ones darkly so. Wings subhyaline, darker in the 
marginal cell and at the apex; stigma piceous. 
6. Length 7 to 8 mm. Differs from the female as follows: clypeus 
entirely, supraclypeal area, interantennal area and the raised line to the 
anterior ocellus, broad lateral marks on the frons as in the female, all 
yellow; apices of the mandibles bright red; first joint of the flagellum but 
slightly longer than the second; clypeus as usual in the males; mesepi- 
sterna not toothed; no spot! on postero-lateral angles of propodeum; 
pygidial area somewhat pyriform, punctured; anterior femora and tibiae 
normal, not flattened; otherwise as in the female. 
Type, a female collected at Auburn, California, September 20, 
1916 (L. Bruner). Allotype, a male collected at Auburn, Cali- 
fornia, September 20, 1916 (L. Bruner). Two male paratypes 
collected at the same time and place. One male paratype col- 
lected at Auburn, July 15, 1916 (L. Bruner). 
May be readily recognized by the flattened and excavated an- 
terior femora, the toothed mesepisterna, the structure of the 
clypeus and the maculation of the thorax.
