Genus PERILAMPUS Latreille

 designated by Gahan and Fagan, U. S. Nat. Mus. Bull. 124, p. 41, 1923.) 



Head as broad as thorax; fron to vertex deeply emarginate; clypeus 

 clearly defined, separated from rest of face by a suture; mandibles 

 strong, the right tridentate, the left bidentate; antennae inserted 

 about in the middle of the head, well above level of lower margins 

 of eyes, with 13 distinct segments, with only one ring joint, scape 

 not quite reaching anterior ocellus, flagellum fusiform to subclavate; 

 thorax coarsely umbilicately punctured; pronotum short; dorsal 

 line of prepectus generally as long as or longer than prothorax, 

 suture separating it from latter sometimes indistinct; mesonotum 

 with parapsidal furrows converging; axillae triangular, not widely 

 separated; scutellum sometimes produced at apex but never produced 

 into a spear-shaped process or spine; costal cell about two to three 

 times as long as the marginal vein; marginal vein longer than the 

 postmarginal, rarely only as long; stigmal vein shorter than post- 

 marginal, very rarely about as long; abdomen very shortly petiolated; 

 first tergite (petiole) transversely linear to nearly as long as broad, 

 with anterior margin frequently elevated into a flangelike projection, 

 smooth to coarsely sculptured; abdomen entirely or in greater part 

 smooth and pohshed, second and third segments (first and second 

 of the gaster) entirely or almost entirely covering remaining segments. 



The species of Perilampus appear to be largely hyperparasitic. 

 They are characterized by an active first-stage larva, termed "plani-
