except the middle of tergites one to eight (broader basally), yel- 

 lowish; the margin of the prescutum, lateral margin of the scutum, 

 part of the scutellum and upper part of the mesepisternum, ferriigi 

 nous; wings hyaline, iridescent, venation pale brown, costa and 

 stigma yellowish.

 labeled " from the Chittenden collection."

ACORDULECERA HICORIAE. new species. 



From caryae Rohwer, to which this new species seems to be most 

 nearly allied, it may be separated by the black clypeus. 



Female.— Length, 3.5 mm. Clypeus truncate; antennal foveae 

 rather large, extending to the supraclypeal foveae ; supraclypeal area 

 slightly convex; middle fovea wanting; ocellar basin wanting; an- 

 tennal furrows complete to the lateral ocelli; postocellar area not 

 indicated ; postocellar line distinctly longer than the ocelocular line ; 

 first joint of the flagellum markedly longer than the second ; front 

 sparsely clothed with short gray hair; stigma broadest at base, 

 tapering rapidly toward the apex. Black; palpi, labrum and legs 

 below the coxae yellowish; antennae piceous; wings dusky hyaline, 

 venation dark brown. 



Type-locality.— Charter Oak, Pennsylvania. Described from 

 three females (one type) recorded under Bureau of Entomology No. 

 Hopk. U. S. 11364a/ larvae collected feeding on Htcoria, by T. E. 

 Snyder; adults, which were reared by William Middleton, emerged 

 May 20, 1914. 



Type.— Cat. No. 18314, U.S.N.M. 



Suborder Clistogastra. 



Superfamily ICHNEUMONOIDEA. 



Family EVANIIDAE. 



PRISTAULACUS STRANGALIAE. new specieg. 



Female.— hength 11.5 mm. Compared with the metatype of Pris- 

 taulacus favicrurus Bradley from the Agricultural College, Michi- 

 gan, this species differs as follows: The front impunctate; the hind 

 coxae hardly aciculate; posterior femora black; the upper part of 

 the mesepisternum shining, sparsely punctured; metapleurae shining, 

 below irregularly recticulate, above with a few strong, irregular 

 carinae; the first tergite has a strong spine at the lateral middle. 

 This last-mentioned character, if constant, will separate strangaliafi 

 from all other species of PHstavlacus.
