ICHNEUMON-FLIES — GELINAE I MESOSTENESTI 133 



Basal 0.2 i: of hind basitarsus white; punctures on second tergite of female 

 separated by about 0.2 to 0.8 their diameter; hind tibia white basally or sub- 

 basally except in /. laurae 3 



3. Basal 0.2 ± of hind tibia light brown, or sometimes with a small whitish area; 



head black, the clypeus and entire scape fulvous; apical carina of propodeum 

 distinct medially, indistinct submedially, and distinct again sublaterally. 



3. laurae, new species 



Basal 0.2 ± of hind tibia mostly or entirely white; head, clypeus, and scape 



variously colored, almost never with the exact combination described for 



I. laurae; apical carina of propodeum distinct throughout 4 



4. Head and thorax entirely black except that sometimes the subtegular ridge has 



a small white mark; tyloids thin and sharp, extending 0.90 i the length 

 of several segments and parallel to the long axes of the segments. 



1. latus (Provancher) 

 Head and thorax usually partly pale, especially with some whitish or brownish 

 on clypeus, hind corner of pronotum, or scutellum; tyloids rather blunt, 

 on several segments extending 0.75 ± the length of the segment, a little 

 oblique to the long axis of the segments. (Some specimens colored just as 

 in latus pinguis but distinguishable on the tyloids and minor structural 

 differences as discussed under latus.) 2. cinctipes (Walsh) 



5. Frons polished, smooth, with very fine sparse punctures; apical carina of 



propodeum lacking 7. laevifrons, new species 



Frons mat, rugulose medially; apical carina of propodeum often present 

 sublaterally 6 



6. Scutellum with lateral carinae on its basal 0.3 ± in male, on its basal 0.4 ± in 



female 7 



Scutellum without lateral carinae except on its basal corners 8 



7. Punctures on scutellum of male separated by about 0.7 their diameter, on 



scutellum of female separated by about 0.5 their diameter; punctures on 

 lateral lobe of mesoscutum separated by about 0.5 their diameter; the part 

 of female first tergite behind the spiracle about 0.75 as long as wide; meta- 

 pleurum of male usually less than half white . . 5. inquisitorius (Miiller) 

 Punctures on scutellum of male separated by about 0.3 their diameter, on 

 scutellum of female the punctures almost touching; punctures on lateral 

 lobe of mesoscutum very dense, subadjacent; the part of female first tergite 

 behind the spiracle about 0.90 as long as wide; metapleurum of male almost 

 entirely white; propodeum of male with a pair of white spots basad of the 

 basal carina 6. velutinus, new species 



8. Hind coxa mostly or entirely fulvous or ferruginous 9 



Hind coxa mostly or entirely black or fuscous 10 



9. Mesoscutum mat, with fine punctures that are separated by about 1.8 their 



diameter; hind tibia with a basal or subbasal pale brown or stramineous 



band 8. rhomboidalis (Walsh) 



Mesoscutum polished, with small punctures that are separated by about 1.0 

 their diameter; hind tibia without a basal or subbasal pale band. 



11. lautus, new species 

 10. Mesopleurum with dense, fine wrinkling, its punctures indistinct. 



9. minor, new species 



Mesopleurum rather smooth, polished, and with fine punctures and often also 



a little weak, fine wrinkling 10. politus, new species
