CHALCID FLIES OF GENUS PERILAMPUS — SMULYAN 385 



between lateral ocellus and nearest point on carina very distinctly 

 exceeding shortest distance from this point on carina to anterior 

 ocellus, apex of emargination falling distinctly in front of a line tan- 

 gent to anterior margins of lateral ocelli ; postocellar line equal to or 

 not greatly exceeding median line of vertex; scrobal cavity deep, its 

 sides sloping steeply and steep slope continued more or less to level 

 of base of clypeus so that hyperclypeal area appears relatively 

 depressed; eyes with a dull surface; face at side of clypeus rugulose 

 or rugose-granular or rather coarsely granular; malar furrow present 

 but sometimes weak; clypeus very distinctly wider than long and 

 about one and one-half tim-cs as long as hyperclypeal area, its ante- 

 rior margin medially truncate or practically truncate, its basal margin 

 usually faintly arcuate; cheeks convexly rounded, the striae on same 

 not crossing malar furrow onto face; head in front view more or less 

 transverse, eyes reaching level of base of clypeus (in some males 

 reaching distinctly below). 



Thorax: Walls between umbilicate punctures on mesoscutum and 

 scutellum, at least along the median line, distinctly thickened and 

 reticulated (not always so distinctly in the males), the interspaces; 

 elsew^here also conspicuously sculptured; punctures on mesoscutum 

 and scutellum round or roundish; area along inner margin of parap- 

 sides in part usually weakly shagreened or aciculate; suture separat- 

 ing prepectus from pronotum sometimes distinct; axilla with an 

 elongate fingerlike extension running posteriorly along the lateral 

 margin of the scutellum, the base of this extension failing more or 

 less distinctly below middle of axilla; face of axilla more or less de- 

 pressed 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 and 

 without conspicuous rugae immediately above base of extension; 

 basal shallow furrows on underside of apex of scutellum turning 

 caudad mediallj-; outer portion of mediolateral areas of propodeum 

 usually neither depressed nor difi'ering materiall}'^ in sculpture from 

 surface as a whole; postmarginal vein occupying about one-sixth 

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

 and apex of mng in a straight line, about one-half the length of 

 marginal vein '"; wing hairs quite dense and dark. 



Abdomen: Posterior face wider than long or about as long as 

 wide; first tergite strongly transverse and usually in part sculptured, 

 its anterior margin not or bat slightly elevated, truncate or practically 

 so, sometim-cs appearing as if shallowly and broadly arcuate, at least 

 in the males; third segment (second of the gaster) usually not exposed,, 

 rarely slightly so. 



i» The posterior limit of the postmarginal vein is sometimes rather difficult to make out, the vein mergin g: 

 with the costal border of the wing.
