134 FAMILY EVANIID^. 



Semceodogaster. The climax of the series is reached in Evanielhis 

 (Fig. 87), where only G, So + R + M and the stigma remain. This 

 genus is at the summit of the family so far as the specialization of 

 its wings is concerned. The posterior wings of all the genera have 

 an almost separated posterior lobe (Figs. 76 and 86} ; there is never 

 more than R -|- M present along the costal margin and another 

 vein within, and frequently this latter vein is also lost. It probably 

 is Cu and M4. The wings are hyaline, with the exceptions of a few 

 exotic species. 



In 1887 Cameron first recognized this subfamily including in it 

 Gasteruption (Fmmis). The date on Cameron's paper is November. 

 Almost simultaneously Cresson recognized the subfamily in his 

 "Synopsis of the Hyraenoptera North of Mexico," dated 1887, with- 

 out statement of the month. The copy before me was received by 

 the Cornell Library, December 28, 1887, so that it is likely that 

 Cameron's paper antedated Cresson's, as the later was probably 

 mailed to Cornell immediately on publication. Kieffer also gives 

 Cameron credit for the subfamily. Schletterer in his monograph 

 recognized the subfamily, and placed Gasteruption in Aulacinaj, 

 instead of Evaniinse, and Ashmead in Smith's " Catalogue of the 

 Insects of New Jersey," 1900, p. 563, recognized it, but as including 

 Gasterupttion. In his "Classification of the Ichneumonoidea," 1901, 

 Ashmead separated Gasteruption from the Evaniinse, and in this last 

 sense the subfamily was recognized in my paper on "North Amer- 

 ican Evaniidje," Tr. Amer. Ent. Soc, 1901, and by Kieffer in the 

 "Genera Insectorum," 1902. 



Up to the time of Schletterer's monograph of the family, three 

 genera had been recognized, Evan.ia, Hyptia and Brachi/gaster. Dr. 

 Schletterer threw these all together into the single genus Evania. 

 Recently Kieffer has recognized a new genus, Zeuxevania ; Szepligeti 

 Evaniscus ; and Enderlein Evaniellns ; shortly before Enderlein 

 erected Evaniellns I established an Evaniella, and here describe 

 three other genera. Pseudevania is a misprint for Zeuxevania. 



Evania is of almost world wide distribution, being found in every 

 region except the Australian, in which one species, perhaps acci- 

 dental, occurs, and three others just over the boarder line from ihe 

 Oriental. But Evania appendigaster is believed to have spread 

 from Europe to all regions, and is everywhere one of the (.•onnnonest 

 species.
