NO. 3533 CHALCID WASPS OF GENUS EURYTOMA — BUGBEE 503 



.24 mm. (.20-.27) and postmarginal averages .18 mm. (.17-.20) in 

 length. 



Male: Black. Averages 1.6 mm. (1.1-2.1) in length. Scape with 

 outer face black to dark bro^vn. Black to dark brown on all femora 

 and tibiae of legs, except for knees and apices which are yellowish 

 brown. Wing veins light yellow; marginal averages .23 mm. (.20-.27) 

 and postmarginal averages .18 mm. (.15-.22) in length. 



Types: 8 females and 6 males. Holotype female, allotype male, 

 and paratypes in U.S. National Museum (USNM 66063). Paratype 

 specimens in the Bugbee collection, Allegheny College, MeadvUle, Pa. 



Type locahty: Crown Point, N.Y., July 19, 1934, O. H. Hammer 

 collection. 



Distribution: United States: New York, Kansas, Washington. 



Host: Bred from apple curculio material, Tachypterellus quadri- 

 gibbus (Say), T. q. magnus List, and T. consors Dietz. 



Remarks: This species is close to Eurytoma mali, new species, but 

 can be separated from it by its much smaller size, more black to 

 dark-brown infuscation on the legs, and the shallower more uniformly 

 punctate propodeum. 



It is probably a primary parasite of the apple curculio. Specimens 

 which were determined as Eurytoma tylodermatis have been shown by 

 Parker and Lamerson (1934) and Hammer (1936) to be external para- 

 sites of the larvae, pupae, and occasionally adults of T.q. magnus List 

 and T. quadngibbus (Say). Although this smaller species is bred from 

 the Apple Curculio along with E. mali, and both species occurred in 

 the same series, they can be easily separated by the characteristics 

 mentioned above.

 Eurytoma iniquus Bugbee, 1951, pp. 253, 254. — Burks, 1958, p. 81. 



Types: Holotype female and allotype male in the U.S. National 

 Museum, Washington, D.C. (USNM 61235). Paratypes in the 

 Bugbee collection, Allegheny College, Meadville, Pa. 



Type locality: Manitou, Colo. 



Distribution: United States: Colorado. 



Host: Diplolepis neglecta (Gillette) (=Z>. tuberculatrix) on Rosa 

 species. 



Remarks: The short ninth tergum averaging .15 mm. in length, 

 combined with the broad marginal vein in contrast to the linear post- 

 marginal, and the narrow dorsal valves that turn at right angles 

 dorsally, anteriorly, with the ventral valves so that the stylet arch is 

 vertical, help to characterize this species.
