ART. 2. ICHNEUMON-FLY GENUS METEORUS MUESEBECK. 39 



extends to extreme apical border of scutum; scutellum broad at base, 

 stronglj^ convex, with a few minute punctures; propodeum rather 

 evenly ruguloso-reticulate ; propleura shining, slightly crenulate in 

 the depression; mesopleura smooth and polished on upper half, 

 finely granularly rugulose in the broad depression on lower half; 

 metapleura opaque, granular or rugulose; wings almost identical 

 with those of Jiyphantriae; first abscissa of radius much shorter than 

 second, but more than half as long; stigma is apparently very slightly 

 narrower and radial cell slightly shorter than in Jiyphantriae; legs 

 slender; posterior coxae more or less roughened above and somewhat 

 punctate on outer face; abdomen about as long as head and thorax 

 united, strongly petiolate; first segment with postpetiole broad, the 

 distance between spiracles more than half the distance from spiracles 

 to apex of segment; postpetiole shining, striate, the striae converging 

 more or less posteriorly; remainder of abdomen smooth and polished; 

 ovipositor sheaths about half as long as abdomen. Ferrugino- 

 testaceous; antennae dark brown, flagellum much darker than scape; 

 propod'eum with blackish markings basally on either side; post- 

 petiole somewhat dusky laterally; wings hyaline, the stigma more or 

 less brown behind, darker than usual in Jiyphantriae; posterior tibiae 

 yellowish, with a conspicuous blackish annulus near base and the 

 apical fifth black. 



Type.— Cat. No. 25413, U.S.N.M. 



Type locality. — Somerville, New Jersey. 



Hosts. — Datana integerrima Grote and Robinson; D. ministra 

 Drury; D. angusii Grote and Robinson. 



Described from five female specimens reared in August, 1921, in 

 the Bureau of Entomology, under gypsy moth laboratory Nos. 

 11744a5 and 11734a7, by R. T. Webber. 



In addition to the type series which has been deposited in the 

 United States National Museum I have seen four other female speci- 

 mens; one, taken by H. M. Parshley at Orono, Maine, is in the col- 

 lection of Dr. C. T. Brues, of Harvard University; two are in the col- 

 lection of the gypsy-moth parasite laboratory, at Melrose Highlands, 

 Massachusetts; one of these was reared from Datana integerrima at 

 Reddington, New Jersey, under gypsy moth laboratory No. 11744a3; 

 the other was reared from D. angusii taken at South Brunswick, 

 New Jersey, under gypsy moth laboratory No. 12175gl; and one 

 specimen reared from Datana ministra, at Overbrook, Pennsylvania, 

 is in the collection of Bureau of Plant Industry at Harrisburg, Penn- 

 sylvania. 



Wliile it is possible that this is only a form of the variable Jiyphan- 

 triae, it is sufficiently constant in the characters in which it differs 

 from that species to warrant holding it distinct, for the present.
