333,f; genitalia as in figure 349, the apex of clasper broadly, weakly 

 emarginate and the penis with a dorsal lobe that in side view makes 

 it appear briefly bifurcate. 



Black. Clypeus ferruginous; scape with a light brown area in front; 

 palpi whitish, brown at base; tegula white; hind corner of pronotum 

 pale fulvous; mesosternum and lower part of mesopleurum sometimes 

 light brown; front and middle coxae and femora fulvous, the femora 

 yellowish, fulvous apically and in front toward apex; front and middle 

 trochanters yellowish fulvous; front and middle tibiae and tarsi 

 pale fulvous, the front of front tibia yellowish fulvous; hind coxa, 

 trochanters, and femur fulvous, the femur with an apical infuscate 

 band, the apical margin stramineous; hind tibia and tarsus infuscate, 

 the base of tibia and of basitarsus and under side of tibia except 

 near apex stramineous. 



Female: Front wing 8.5 to 10.3 mm. long; face rather short, with 

 moderate sized, sharp, close punctures, but near eye relatively im- 

 punctate except for vertical row of smaller punctures paralleling 

 inner margin of eye; prepectal carina exceptionally short, its dorsal 

 end at level of lower 0.15 of hind margin of pronotum; hind femur 

 about 4.5 as long as deep, the hairs on its front face moderately 

 sparse; spinelike bristles on hind tibia very strong and numerous; 

 punctures on propodeum moderately sharp and dense, the interspaces 

 of the sublateral ones about 0.5 their diameter; median longitudinal 

 carinae of propodeum rather weak, extending about half the length 

 of propodeum; first tergite about 1.3 as long as wide; second tergite 

 about 0.95 as long as wide; third tergite polished, its tubercles rounded, 

 subcircular, rather prominent, polished, and covered with moderately 

 sharp punctures whose interspaces are about 0.6 their diameter; 

 ovipositor sheath about 1.25 as long as front wing, its hairs unusually 

 long; tip of lower valve of ovipositor as in figure 330, e, the teeth 

 apicad of its dorsal lobe unusually oblique and closely spaced. 



Black. Clypeus ferruginous; maxillary palpus brown, its base 

 darker brown; labial palpus dark brown; tegula pale yellowish, fulvous 

 apically; small hind corner of pronotum fulvous; mesosternum and 

 lower part of mesopleurum sometimes light brown; front and middle 

 legs fulvous; hind coxa, trochanters, and femur fulvous, the femur 

 not fuscous on apex; hind tibia and tarsus dark reddish fuscous, the 

 tibia a very little paler basally. 



The male is easily distinguished by the emarginately truncate 

 genital clasper and the dorsal lobe on the apex of the penis. In the 

 female, the apex of the lower valve of the ovipositor is distinctive, 

 but this character is so minute that the short prepectal carina, lack 

 of fuscous at the apex of the hind femur, short first tergite, and short 

 ovipositor sheath are more generally useful characters, and the
