16 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 82 



Both fuscipennis and ewphydryadis are parasitic on species of the 

 lepidopterous genus EupJiydryas. 



The second species of Zachrestoides^ intermedm Viereck, is un- 

 known to me, but from its possession of the complete areolet I doubt 

 if it is really congeneric with the other two species. 



BENJAMINLA. FUSCIPENNIS (Provancher) 



T^yp^.—U.S.N.M. No. 1967. 



Several specimens besides the type are in the National Museum. 

 All but one from Reno, Nev., are from California, and all but the 

 Nevada specimen were reared from the type host, Euphydryas chal- 

 cedon Doubleday and Hewitson. 



The wings in the male are nearly hyaline. 



The bright ferruginous legs, and, in the female, the dark wings 

 distinguish the species from eupJiydryadis. 



BENJAMINLA EUPHYDRYADIS (Viereck), new combination 



ZacJirestoides euphydryaMs Vieeeck, Can. Ent., vol. 58, p. 3, 1926. 



One female and three males, reared at the Gipsy Moth Parasite 

 Laboratory, Melrose Highlands, Mass., under Nos. 12410H2, N2 

 and 51 and 12411E2, from various localities in eastern Massachu- 

 setts, are before me. The host in each case was Euphydryas phaeton 

 (Drury), the same as Viereck 's type. 



These specimens differ consistently from the original description 

 in their darker palpi and legs and reddish abdominal venter, prob- 

 ably being more fully matured than the type. 



The species is at once distinguishable from fiuscipennis by its 

 hyaline wings and darker legs. 



Genus TRANOSEMA (Foerster) Thomson 



TRANOSEMA PEDELLA (Holmgren) 



A series of what appears to be this species has been received from 

 the Gipsy Moth Parasite Laboratory. They were reared as para- 

 sites of the birch leaf-mining sawfly, PhyllotOTna neTTborata (Fallen), 

 from material imported from Austria in connection with the intro- 

 duction of parasites of that species into a severe infestation in 

 northern New England. 



None of the specimens is typical pedella\ but several agree very 

 closely with Holmgren's var. 1 in having the front and middle coxae 

 entirely pale and only the hind pair black. Some specimens, how- 

 ever, have the hind coxae virtually entirely ferruginous. Between 

 these two extremes stand other specimens with the coxae partly 

 blackish. The hind tibia varies from pale ferruginous with only 

 the apex blackish above to ferruginous only below with the upper 

 surface yellowish in the middle and blackish at both base and apex. 

 The stigma varies from dark to light fuscous. 



Liberated at North Conway, N. H., in 1931.
