 Types: 4 cf , Stanford University, Calif. (Ithaca). (New synonymy.) 



Ovipositor sheath about 1.55 as long as the jorewing, with only its 

 apical 0.05 ± pale. 



Forewing about 6.0 mm. long; top of head with very close fine 

 punctures and very fine, close, irregular, transverse wrinkling; temple 

 weakly convex. Head about 0.47 as wide at occipital carina as at 

 eyes; occipital carina separated from the head by a rounded groove, 

 about 0.2 as wide as the flagellum, transversely striate basally and 

 somewhat reiflexed; propleurum about 1.1 as long as the width of the 

 mesoscutum, irregularly rugosopunctate, more finely so basally and 

 more coarsely apically; lateral lobe of mesoscutum mat, with irregular 

 fine and coarse punctures that are confluent with irregular or somewhat 

 transverse wrinkling; ovipositor sheath about 1.55 as long as the 

 forewing. 



Blackish. Clypeus except at its base and mouthparts brownish 

 ferruginous; flagellum more or less stained with brownish ferruginous, 

 darkest above, on the basal few flagellar segments, and on the apical 

 segment; prothorax varying from ferruginous to blackish; tegula 

 ferruginous; front and middle legs ferruginous, their tibiae with paler 

 external and basal marks; hind leg ferruginous-brown, the coxa ferru- 

 ginous basally and the trochanters and more or less of the apical part 

 of the coxa more or less infuscate; hind tibia with a whitish subbasal 

 band ; abdomen varying from mostly blackish with the second to fifth 

 incisures broadly ferruginous, to mostly ferruginous with the tergites 

 a little infuscate dorsally (except at their bases and apices) and the 

 apical few tergites largely infuscate. Occasional specimens have the 

 head and body almost entirely ferruginous, and in some the ferru- 

 ginous coloration is more restricted than indicated above. Ovipositor 

 sheath blackish with the apical 0.05 ± ferruginous or dirty white.
