CHALCID FLIES OF GENUS PERILAMPUS — SMULYAN 387 



touching a line tangent to anterior margins of lateral ocelli; posto- 

 ceilar line very distincth^ longer than median line of vertex, sometimes 

 more than twice as long (not so distinctly so in the males), usually 

 about twice as long as ocellocular line; lateral ocelli not depressed 

 and vertex medially not elevated; sides of scrobal cavity " not very 

 steep (usually steeper in males) and face at side of h3^perclypeal area 

 quite strongly flaring, the hyperclypeal area relatively not at all or 

 but slightly depressed; eyes wuth a dull surface; face at sides of 

 cl3'peus finely rugulose, or rugose-granular, this sculpture sometimes 

 extending above level of base of clypeus; malar furrow present but 

 sometimes faint (in the males, rarely, practically absent); clypeus 

 distinctly wdder than long and distinctly longer than hyperclypeal 

 area, its anterior margin medially broadlj^ and shallowly arcuate to 

 practically truncate, basal margin weakly to quite distinctly arcuate ; 

 cheeks convexly rounded, the striae on same usually not crossing 

 malar furrow onto face; head in front view more or less transverse, 

 eyes reaching or about reaching level of base of clypeus (generally 

 reacliing distinctly beyond in the males). 



Thorax: Mesoscutum and scutellum coarsely punctate, the walls 

 between punctures on prothorax as a rule in large part widened ; area 

 along inner margin of parapsides smooth or practically smooth and 

 polished; suture separating prepectus from pronotum as a rule 

 indistinct; axilla i\ith an extension running posteriorly along lateral 

 margin of scutellum, this extension sometimes not much longer than 

 wide, its base falling more or less distinctly below middle of axilla; 

 face of axilla more or less depressed or excavated immediately above 

 base of extension, the portion immediately anterior to extension not 

 sloping toward latter; surface of axilla completely sculptured and 

 opaque or subopaque, the upper part sometimes rather finely sculp- 

 tured and shining, usually without very conspicuous rugae immedi- 

 ately above base of extension; basal shallow furrows on underside of 

 apex of scutellum turning caudad medially; outer portion of medio- 

 lateral areas of propodeum usually not depressed, sometimes with 

 coarse or conspicuous rugae but usuallj^ not differing materially from 

 greater part of surface, the surface adjacent to median carina usually 

 excavated and rugulose ; postmarginal vein occupying about one-sixth 

 or less than one-sixth the distance between end of marginal vein and 

 apex of wing in a straight line, sometimes not much longer than 

 stigmal vein, slightly less than one-half to nearly two-thirds the 

 length of marginal vein, the end distinctly visible; wing hairs rather 

 short and not dense, mostly pale but with some darker hairs on 

 apical portion of wing (in the males the apex of postmarginal vein 

 sometimes indistinct and the hair of the entire wing sometimes dark 

 and longer). 



II lu the broad sense, the portion included between the carinae.
