yellow; legs brownish-yellow except front 
coxa posteriorly and hind coxa anteriorly in- 
fuscated. Propodeum greenish to brownish- 
yellow except for the median depression, 
shallow groove below propodeal spiracle, and 
circular depression near posterior margin 
which are dark brown to black; tergum III 
(apparent first) , except yellowish spot at side 
and sterna, black; each of terga IV-VI in- 
clusive bordered posteriorly by narrow amber 
margin and with a circular lateral black spot 
above, otherwise these terga are predomi- 
nantly reddish-brown above and light yellow 
at sides; tergum VII yellow except for narrow 
posterior amber margin. 
Pubescence on body rather fine and sparse, 
black on antennae and dorsal areas of body 
and wings, remainder pale. Wings subhya- 
line; with fine, short, dense vestiture along 
whole anterior margin of costal cell of front 
wing; venation rather strong, proximal two- 
thirds of submarginal vein with 12-13 con- 
spicuous bristles; stigmal vein short, stigma 
large, quadrate, the stigmal sector short, both 
surrounded with narrow infuscation (Fig. 2); 
venation dark brown or black.

Female: Length 12.3 mm.; abdomen 5.5 
mm. Ovipositor 31.5 mm. Structure of head 
and thorax, except for antennae and wings, 
much like that described for the male; scape 
compressed, slightly bent, about as long as 
pedicel, ring segment, FI, and one-half of FII 
combined; funicular segments subcylindrical, 
decreasing slightly in length progressively in 
more distal segments, the proximal ones more 
than twice as long as thick. Propodeum only 
slightly depressed medially, sculptured with 
coarser more irregular rugae; abdomen com- 
pressed; ovipositor slender. 
Head colored as in the male but less in- 
fuscated below and within antennal scrobe; 
antennae black except for the scape and pedi- 
cel, which are brown. Thorax colored as in 
the male but the median dorsal black stripe 
is more extensive and intensified, being weak 
or interrupted only on the anterior areas of 
both mesopraescutum and mesoscutellum; 
prepectus and mesepisternum lighter, and 
front and hind coxae without pronounced in- 
fuscation. Abdomen dark amber to brown 
except terga IV (apparent second) to VIII 
inclusive, each with yellow spot at side di- 
rected dorsad. Ovipositor sheath black. 
Vestiture like that of male except proximal 
two-thirds of submarginal vein with about 
14 conspicuous bristles, and dense vestiture 
present only on distal half of costal margin; 
wings subhyaline, venation strong, dark 
brown or black; stigma rather small (Fig. 3 ) , 
somewhat oval, narrowly surrounded with 
infuscation; stigmal vein rather thick, about 
as long as greatest stigmal width, surrounded 
with narrow infuscation.
