CHALCID FLIES OF GENUS PERILAMPUS — SMULYAN 373 



Postocellar line three or more times as long as median line of 

 vertex, about twice length of ocelloculaf line; emargination 

 of fronto vertex almost touching a line tangent to posterior 

 margins of lateral ocelli; scutellum produced at apex and as 

 a rule distinctly longer than mesoscutura and prothorax 

 together; head and thorax green, antennal flagellum grayish 

 black carolinensis, new species 



5. Frontal scrobe above narrowly arcuate; distance between lateral 



ocellus and nearest point on frontal carina about equaling or 

 exceeding shortest distance from that point on carina to 

 anterior ocellus; if shorter (plaiygaster Say), then clypeus as 



a rule as long or about as long as wide 6 



Frontal scrobe more broadly arcuate; distance between lateral 

 ocellus and nearest point on frontal carina (or edge of emargi- 

 nation) shorter than shortest distance between that point on 

 carina and anterior ocellus; if about equal (carinifrons Craw- 

 ford), then face at side of clypeus smooth except for hair 

 punctures 7 



6. Shortest distance between lateral ocellus and frontal carina 



about equal to or shorter than shortest distance from that 

 point in carina to anterior ocellus; if longer, then emargina- 

 tion of frontovertex touching a line tangent to anterior mar- 

 gins of lateral ocelli and postocellar line considerably longer 

 than median line of vertex; area along inner margin of parap- 

 sides distinctly and completely or practically completely 

 shagreened; walls between umbilicate punctures on mesoscu- 

 tum thin, mere septa; clypeus as a rule about as long as 



wide platygaster Say 



Shortest distance between lateral ocellus and frontal carina 

 exceeding shortest distance from that point in carina to 

 anterior ocellus; emargination of frontovertex falling dis- 

 tinctly in front of a line tangent to anterior margins of lateral 

 ocelli and postocellar line not greatly longer than median 

 line of vertex; area along inner margin of parapsides only in 

 small part shagreened and that rather faintly so; walls be- 

 tween umbilicate punctures on mesoscutum widened or 

 thickened, at least medially; clypeus very distinctly wider 

 than long crawfordi, new species 



7. Area along inner margin of parapsides completely or practically 



completely sculptured, shagreened, or shagreened and acicu- 

 late; lateral ocelli distinctly depressed, vertex medially more 

 or less distinctly elevated, this elevation continued diagon- 

 ally in front of lateral ocelli; hyperclypeal area about as long 

 as clypeus. Face at side of clypeus rugulose, rugulose granu- 

 lar, or granular; eyes with a vitreous surface ocellatvis, new species 



Area along inner margin of parapsides smooth or practically 

 smooth and polished; lateral ocelli not depressed and vertex 

 medially relatively not elevated, although rarely faintly so; 

 hyperclypeal area distinctly shorter than clypeus 8 



8. Face laterad of clypeus rugulose, rugose, or rugose-granular; 



frons laterad of frontal carina and ocellocular area very often 

 distinctly sculptured; eyes with a dull surface; anterior margin 



of first tergite more or less distinctly emarginate subcarinatus Crawford 



Face laterad of clypeus, frons laterad of frontal carina, and 

 ocellocular area smooth except for hair punctures; surface of
