CHALCID FLIES OF GENUS PERILAMPUS — SMULYAN 375 



Upper part of frons smooth; malar furrow more than half as 

 long as width of cheek at apex (rarely no more than half) ; 

 pronotum laterally as long as dorsal margin of prepectus or 

 not much shorter; head black, occasionally with some blue- 

 green or bronzy reflections 13 



13. Frons meeting vertex in a curve; emargination of frontovertex 



acute or at least not markedly obtuse; anterior and posterior 

 margins of prepectus carinate and gradually converging ven- 

 trally to form a single carina; scutellum not broadened api- 

 cally, at most only slightly broader; thorax not completely 

 black, notum at least greenish, bluish, brqnzy, or cupreous 



(bright coloring sometimes very limited) rohweri, new species 



Frons meeting vertex in a sharp keel; emargination of fronto- 

 vertex markedly obtuse; carina along anterior margin of pre- 

 pectus curved sharply caudad to meet posterior marginal 

 carina at an approximate right angle at a point about half the 

 distance between tegula and front coxa; scutellum more or 

 less distinctly broadened apically; thorax black (punctate 

 portion of notum sometimes bronzy black) capitatus, new species 



14. Third joint (ring joint) of antennae, except rarely, as long as 



wide; pronotum laterally as a rule no longer and generally not 

 so long as dorsal margin of prepectus^; scutellum not granular 



laterad anomocerus Crawford 



Third joint of antennae wider than long; pronotum laterally 

 longer than dorsal margin of prepectus; scutellum densely 

 granular laterad granulosus Crawford 



15. General color black with greenish and cupreous reflections; face 



and areas along inner margins of parapsides distinctly green- 

 ish; vertex and dorsum of thorax usually more or less cupre- 

 ous; cheeks along malar furrow, frons, and face, exclusive of 

 hyperclypeal area and clypeus, completely or in greater part 

 finely and irregularly lineolate or aciculate. Cheeks convexly 



rounded; head in front view transverse gahani, new species 



General color black or blackish (head very rarely greenish and 

 notum of thorax sometimes bronzy) ; front and face, except 

 very rarely, entirely smooth except for hair punctures; cheeks 

 along malar furrow usually smooth 16 



16. Angle formed by dorsal and anterior faces of pronotum later- 



ally not sharp, the coarse punctation of sides of pronotum 

 continued onto lateral margins of anterior face; punctate por- 

 tion of pronotoprepectal area dorsally shorter than smooth 

 portion; basal shallow furrow on underside of apex of scutel- 

 lum not distinctly angled at middle; neck of propodeum 



weakly sculptured, only rarely coarsely sculptured 17 



Angle formed by dorsal and anterior faces of pronotum sharp 

 laterally as well as above, the coarse punctation of sides of 

 pronotum not continued onto its anterior face; punctate por- 

 tion of pronotoprepectal area dorsally as long or longer than 

 smooth portion; basal shallow furrow on underside of apex 

 of scutellum forming an acute angle medially or sometimes 

 an obtuse angle; neck of propodeum coarsely sculptured, only 

 rarely finely or weakly sculptured 18 



' The suture separating the prepectus from the pronotum may be indistinct.
