CHALCID FLIES OF GENUS PERILAMPUS — SMULYAN 379 



of the scrobal cavity to beyond level of insertion of antennae, its lower 

 portion sharply curving toward eye margin ; ocellocular area and frons 

 laterad of the carina conspicuously wrinkled and with rather large, 

 shallow, irregular punctures; emargination of fronto vertex falling 

 considerably in front of a line tangent to the posterior margins of 

 lateral ocelli, and anterior margin of anterior ocellus well in front of 

 anterior margins of lateral ocelli; postocellar hne twice or less than 

 twice the length of median line of vertex, much less than twice the 

 length of ocellocular line and sometimes only a little longer than the 

 latter; eyes with a conspicuous smooth area along posterior orbit; 

 cheeks and face on each side of clypeus with coarse ridges or rugae, the 

 lowermost rugae on face commingling or continuous with those on 

 cheeks, these rugae well separated, not dense and numerous; malar 

 furrow absent; scrobal cavity deep, its sides beginning to flare some- 

 what above level of base of scape; hyperclypeal area rather strongly 

 depressed in relation to face on each side; clypeus wider than long, 

 longer than hyperclypeal area (sometimes nearly twice as long), its 

 anterior margin shallowly but distinctly arcuate; cheeks convexly 

 rounded; head in front view distinctly transverse; eyes reaching 

 level of base of clypeus. 



Thorax: Scutellum about as long as or not much longer than meso- 

 scutum and pro thorax together; area along inner margin of parapsides 

 shallowly punctate and aciculate; suture separating prepectus from 

 pronotum very distinct; axilla with an elongate fingerlike extension 

 running posteriorly along lateral margin of scutellum, the base of 

 extension falling distinctly below middle of axilla, face of axilla 

 depressed or excavated immediately above base of extension, the por- 

 tion immediately anterior to extension not sloping toward latter, 

 surface of axilla in large part smooth or practically smooth and 

 shining but with more or less conspicuous rugae immediately above 

 base of extension; basal shallow furrows on underside of apex of 

 scutellum turning caudad and meeting in an acute angle on median 

 line of scutellum; propodeum depressed laterad of the smooth median 

 areas; scutellum with a conspicuous smooth median longitudinal line; 

 walls between punctures on mesoscutum medially slightly thickened; 

 wing veins long, the postmarginal vein occupying about one-fourth the 

 distance between marginal vein and apex of wing in a straght line and 

 about three-fourths the length of the marginal vein; wing hairs 

 rather dense. 



Abdomen: Posterior face very distinctly wider than long; first 

 tergite very strongly transverse, apparently smooth and with no 

 elevated anterior margin; hair punctures on second segment fairly 

 conspicuous. 



Color: Head, except face and scrobal cavity wliich are black, bright 

 cupreous with a greenish reflection; hyperclypeal area cupreous to 

 brassy; base of mandibles bluish to violaceous; flagellum of antenna
