projection and the area beneath the projection, supraclypeal and inter- 
antennal areas, broad lateral marks on frons extending up a little beyond 
the insertion of the antennae, scape beneath, flagellum beneath and spot 
behind the eyes, all pale yellow. Mesonotum and scutellum rather sparsely 
punctate; mesepisterna with large, close punctures, produced below me- 
dially, forming a small, blunt tooth; propodeal enclosure finely trans- 
versely rugose with a median impressed line; posterior face of propodeum 
with large, close punctures; lateral faces of propodeum finely longitudi- 
nally striate; large lateral spots on pronotum, tegulae, spot on dorsal 
plate of mesepisterna, two spots on scutellum, and metanotum, all pale 
yellow. Abdomen with strong, rather close punctures; pygidial area pyri- 
form, about three times as long as it is wide at the base, much narrowed 
before the apex, more or less rugose basally; band on tergite one, broad 
band narrowed medially on tergite two, tergites three and four entirely 
except a median semicircular area anteriorly, broad band on tergite five 
narrowed medially, and lateral spots on sternites three and four, all yel- 
low. Legs black; apical half of all the femora, all the tibiae except a 
spot behind at or near the apex, anterior and intermediate tarsi, and 
basal joint of hind tarsi all yellowish. Wings subhyaline, darker at the 
apex and in the marginal cell; stigma testaceous. 
dS. Length 6 to 7 mm. Differs from the female as follows: clypeus 
tridentate anteriorly, without a projection; no spot behind the eyes; no 
spot on dorsal plate of mesepisterna; mesepisterna not toothed; pygidial 
area a little more than twice as long as it is wide at the base, with a few 
punctures, truncate at the apex. 
Type, a female collected at Sacramento, California, October 
3, 1916 (L. Bruner). Allotype, a male collected at Sacramento, 
California, October 6, 1916 (L. Bruner). One female paratype, 
Auburn, California, August 12, 1916 (L. Bruner); one female 
paratype, Auburn, California, August 14, 1915 (L. Bruner) ; two 
female paratypes, Auburn, California, September 20, 1916 (L. 
Bruner) ; one male paratype, Sacramento, California, September 
18, 1916 (L Bruner) and one male paratype, Auburn, California, 
August 12, 1916 (L Bruner). 
Also runs to convergens in Viereck and Cockerell’s table, but 
the markings are distinctly yellow, the propodeal enclosure is 
transversely rugose (not smooth, dull, striatulate at the sides), 
the pygidial area is not constricted and the stigma is testaceous, 
not piceous as in convergens.
