- jection except the margins, lateral spots on clypeus, spot on supraclypeal 
area extending onto the interantennal carina, broad lateral areas on the 
frons extending up above the insertion of the antennae, and spot behind 
the eyes, all yellow; flagellum beneath reddish, above black. Thorax 
strongly punctate; the mesepisterna with large, more or less contiguous 
punctures, thus appearing reticulate; scutellum sparsely punctured; en- 
closure of propodeum strongly longitudinally striate; widely separated 
lateral spots on pronotum, tegulae, metanotum, and elongate spot at the 
postero-lateral angles of the propodeum, all yellow. Abdomen strongly 
punctured; pygidial area widest at the base, narrowed and rounded at the 
apex, about t'wo and one fourth times as long as wide, a few punctures at 
the base, transversely rugose; lateral spots on tergite one, tergites two 
to five entirely except a median, basal, semicircular area, and lateral spot's 
on sternites two to four, all yellow. Legs black; apices of anterior and 
intermediate femora, basal three fourths of posterior femora in front and 
basal half behind, anterior and intermediate tibiae and tarsi, and posterior 
tarsi except the tips, all yellow. Wings subhyaline, darker at the tips, 
stigma reddish. 
3. Length 9 mm. Differs from the female as follows: no clypeal pro- 
jection; clypeus, supraclypeal and interantennal areas entirely yellow; 
scape yellow beneath; propodeum not maculated; tergites with yellow 
bands narrowed medially and broadened at the sides; spots connected | 
apically on sternites two to four; sternite five with small lateral spots; 
legs yellow, except anterior coxae, trochanters and femora behind, inter- 
mediate femora behind basally, posterior femora apically, posterior tibiae 
apically, and posterior tarsi, all of which are black. 
Type, a female collected at Sacramento, California, October 6, 
1916 (L. Bruner). Allotype, a male collected at Sacramento, 
California, October 3, 1916 (L. Bruner). 
May be distinguished by the form of the clypeal projection 
and the extensive yellow maculations of the abdomen. 
Cerceris pudorosa sp. nov. 
2. Length 9 to 10 mm. Black, strongly punctured, very sparsely pu- 
bescent. Clypeus produced, with a free apical edge, the projection low 
but extending beyond the anterior margin of the clypeus, roundly emar- 
ginate medially; clypeus laterally with silvery white pubescence; a raised 
line running from interantennal carina to anterior ocellus; frons very ~ 
strongly and closely punctured; ocelli in a low triangle; first joint of 
flagellum about one and one half times as long as the second; basal half 
of mandibles, clypeus except apical margin of projection, supraclypeal 
dot, broad lateral marks on frons extending up a little beyond the inser- 
tion of the aftennae, scape beneath, and dot behind the eyes, all pale 
yellow; flagellum reddish yellow beneath, black above. Mesonotum and
