which recede dorsally toward anterior margin and continue over 

 dorsal surface in a narrow band; ninth abdommal segment elongate 

 and sharply pointed, averaging .20 mm. (.17-.22) in length. Internal 

 genitalia dorsally extended, anteriorly, so that both dorsal and ventral 

 valves turn dorsad at approximately a right angle in relation to 

 horizontal length; stylet arch in an oblique plane or halfway between 

 a horizontal and vertical plane; dorsal valves not broad, mediumly 

 narrow for horizontal length; whole structure averages 1.6 mm. 

 (1.5-1.7) in length, 1.1 mm. (1.0-1.1) in height. Propodeum con- 

 cave; faint, wide median furrow sometimes indicated by lateral 

 carinae in dorsal half only or often lacking; lateral areas irregularly 

 punctate and ridged. Tegula black. Scape variable, all black or 

 dark brown except base, or outer face all yellowish brown; fiagellum 

 short and stocky; first segment longer than wide; segments two to 

 five becoming progressively shorter so that five is approximately 

 square; six to eight closely grouped, although six is separated from 

 seven by a shallow annulation; flagellum same diameter throughout 

 length, and segments one to five truncate distally. Legs with black 

 to dark brown on all femora and tibiae except sometimes yellowish 

 brown fore tibiae; knees and apices yellowish brown. Wing veins 

 yellow and narrow to linear; marginal either longer than postmarginal 

 or equal to it in length; marginal averages .27 mm. (.25-. 32) in 

 length and postmarginal averages .24 mm. (.22-. 25) ; stigmal club 

 small and rectangular in shape. 



Male: No males in the type series. Two male specimens from 

 Glen Burnie, Md., appear to belong to this series. 



Types: 4 females. Holotype female and paratypes in the U.S. 

 National Museum collection (USNM 66061); additional paratypes 

 (3 females and 2 males) in the Bugbee collection, Meadville, Pa. 



Type locality: Wathena, Kans., emerged July 3-11, 1939, P.G. 

 Lamerson collection. 



Distribution: United States: Kansas, Maryland. 



Host: Parasite (external on larvae) of the Strawberry Leafroller 

 (Ancylis comptana (Frolich)), and hyperparasite (?) of Cremastus 

 cookii Weed, a primary parasite of the Strawberry Leafroller. 



Remarks : This species can be distinguished from E. pini by its more 

 dorsally produced genitalia that turn dorsad anteriorly, at almost a 

 right angle; its smaller size; shorter marginal and postmarginal veins; 

 and the short, stocky antenna with the segments of the flagellum 

 truncate distally. 



The host is a native of Europe; it was introduced into the United 

 States and is now quite widespread. According to Peairs and David- 

 son (1956, p. 495) it is "present over a large part of the United States, 

 from the Mississippi Valley eastward."
