CHALCID FLIBS OF GENUS PERILAMPUS — SMULYAN 389 



carina usually not very prominent; frons laterad of carina and ocell- 

 ocular area smooth; emargination of fron to vertex as a rule rather 

 broadly arcuate, the distance between lateral ocellus and nearest point 

 on carina, or edge of emargination, shorter than shortest distance 

 from this point on carina to anterior ocellus, sometimes about equal; 

 emargination touching or nearly touching line tangent to anterior 

 margins of lateral ocelli; postocellar line distinctl}^ longer than median 

 line of vertex; lateral ocelli not depressed and vertex medially not 

 distinctly elevated although sometimes faintly so; sides of scrobal 

 cavity ^^ not sloping very sb.arply (sometimes steeper in males) and 

 face at side of hyperclypeal area strongly flaring, the hyperclypeal 

 area relatively not depressed or but slightly so; eyes with a vitreous 

 surface; face at side of clypeus smooth except for hair punctures, 

 sometimes weakly sculptured along outer edge; malar furrow present 

 but may be indistinct; clypeus distinctly wider than long and dis- 

 tinctly longer than hyperclypeal area, its anterior margin medially 

 usually faintly arcuate and the basal margin not at all or only very 

 slightly arcuate; cheeks convexly rounded, the striae on same not 

 crossing malar furrow onto face; head in front view transverse, eyes 

 reaching or nearly reaching level of base of clypeus. 



Thorax: Walls between punctures on pro thorax sometimes distinctly 

 widened; mesoscutum very often in part at least rugosopunctate; area 

 along inner margin of parapsides smooth; suture separating prepectus 

 from pronotum indistinct; axilla with an elongate fingerlike extension 

 running posteriorly along lateral margin of scutellum, the base of this 

 extension falling below middle of axilla, face of axilla more or less 

 depressed or excavated immediately above base of extension and the 

 portion imm.ediately anterior to extension not sloping toward latter; 

 surface of axilla completely sculptured and opaque or subopaque, the 

 upper part sometimes more finely sculptiu'ed and sliining, usually 

 without very conspicuous rugae immediately above base of extension ; 

 basal shallow furrows on underside of apex of scutellum turning 

 caudad medially; outer portion of mediolateral areas of propodeum 

 not depressed and not differing materially from greater part of surface, 

 slightly excavated adjacent to median carina; postmarginal vein 

 occupying one-sixth or much less than one-sixth the distance between 

 end of marginal vein and apex of wing in a straight line and about 

 one-half or somewhat more than one-half the length of the marginal 

 vein; wing hairs fairly dense and mostly dark. 



Abdomen: Posterior face somewhat shorter than broad to longer 

 tlian broad; first tergite strongly transverse and more or less sculp- 

 tured, its anterior margin usually more or less elevated and truncate 

 or apparently truncate; tliird segment (second of the gaster) more or 

 less exposed. 



n In the broad sense, the portion included between the carinae.
