longest on the posterior margin at a jtoiiit aI)out three-fourths of the 

 distance from the base to apex, and even here considerably shorter than 

 the stigmal vein; marginal vein more than twice as long as the sub- 

 marginal and provided with about eleven or twelve bristle-like hairs 

 which are rather longer than the cilia on the posterior margin, the 

 submarginal with two bristle-like hairs; costal cell narrow and bare 

 excepting two or three tine cilia near its apex, which are like the other 

 diseal cilia. Hind wings narrow, the cilia on the posterior margin nearly 

 as long as the greatest width of the disk, those on the anterior margin 

 not more than one-fifth as long; diseal ciliatiou distinct except in 

 the basal area opposite the submarginal vein. 



Abdomen about a fourth longer again than the head and thorax 

 combined, the ovipositor sheaths slightly protruded, rather stout and 

 tapering to apex ; sides of abdomen and apical fourth of the dorsum 

 set with fairly numerous pale-colored hairs, the vibrissal plates of the 

 last segment each with one long black seta directed obliquely outward. 



Cheeks very finely lineolate-reticulate, occiput microscopically reticulate, 

 the fronto-vertex and face more alutaceous; mesoscutum and scutellum 

 more finely longitudinally lineolate than the cheeks, some of the micro- 

 scopic impressed lines interlacing ; scutellum with a minute round osteole 

 on each submedian lobe situated about half way between the bristles 

 and somewhat larger than the osteoles in which the bristles themselves 

 are set; these are hardly visible in dry material, but prominent in 

 slide mounts ; parapsides and axillae more coarsely sculptured than 

 the cheeks, the former reticulate, the latter lineolate; pronotum much 

 more roughly sculi)tured than other parts of the thorax, the reticulations, 

 however, hardly coarser than those of the parapsides, metanotum nearly 

 smooth and polished, the propodeum comparatively coarsely but delicately 

 reticulate, and with a median carina furcating in front of the apical 

 neck, the branches extending outward to the sides; abdomen a little 

 more coarsely reticulate than the propodeum. 



Length of body: (0.94 to) 1.53; width of mesoscutum: 0.30(i ; length 

 of abdomen: 0.836; length and width of forewings: 1.24 by 0.428; 

 length and width of hindwings: 1.01 by 0.153; length and width of scape 

 excluding radicle: 0.169 by 0.056; length of pedicel: 0.087; length of 

 fagellum: 0.436; length of first funicle joint: 0.122; length of club: 

 0.143 mm. 



Male: Coloration considerably paler than in the female; head 

 tegulae, underparts of thorax, except metapleura, basal half of abdomen 

 and legs pale yellow (about Naples yellow of Ridgway), the upper part 

 of the occiput with a dusky spot and the vertex somewhat greenish 

 around the ocelli ; pronotum, anterior third of jnesoscutum, ])arapsides, 

 ])ropodeum, metapleura, and apex of abdomen metallic green; remainder 

 of the mesoscutum, axillae and scutellum greenish ycdlow and somewhat 

 metallic in larger specimens witli the apex and sides of tlic scutellum 

 often decidedly nu^tallic green, but in very sin:ill specimens ;i]l of these
