I NO. 3533 CHALCID WASPS OF GENUS EURYTOMA — BUGBEE 501 



slightly longer petiole that has its width about equal to its length, 

 the broad postmarginal vein that is usually twice the length of the 

 marginal, the very wealdy developed female genitalia with wide- 

 spread and broad dorsal valves, and the stylet arch in a horizontal 

 plane make this species quite distinct.

Types: Female holotype and 5 female paratypes in the U.S. National 

 Museum, no. 23779. 



Type locality: Warrenton, Va. Emerged 1917, W. J. Phillips 

 collection, Webster no. 9350. 



Distribution: United States: New York, Virginia, Indiana, Kansas, 

 Ohio, Washington, D.C., Pennsylvania. Canada: Alberta, Saskatch- 

 ewan. 



Host: Harmolita tritici (Fitch) on wheat (Phillips, 1918 and 1927). 

 Lepidopterous galls on Solidago (Giraidt, 1920). 



Additional hosts: Cephus cinctus (Department of Agriculture collec- 

 tion, Ottawa, Canada). 



Remarks: This species has never had a full description pubHshed. 

 PhilHps (1918) pubUshed a picture but did not give a description 

 because he was using a manuscript name given the species by Girault. 

 Girault's paper (1920) was delayed in publication and does not 

 contain a description either but merely a reference to some specimens 

 from Youngstown, Ohio, Front Royal, Va., Holliday, Utah, and 

 Waterloo, N.Y., with a few notes on scape color, wing vein length, 

 and on variation in the median channel of the propodeum. Thus 

 the species is credited to Phillips. I have been unable to discover 

 all the specimens that Girault mentions, but the three females from 

 Falls Church, Va. (R. A. Cushman collection) from lepidopteran 

 galls on Solidago have been determined by me as Eurytoma bolteri 

 Riley. The type specimens in the U.S. National Museum, collected 

 by Philhps, are quite different from E. bolteri. On the basis stated 

 above, I doubt that E. parva has been bred from lepidopterous galls 

 on Solidago as stated in Giraidt's paper. 



In the description of Eurytoma atripes, Gahan (1933) points out that 

 E. atripes and E. parva are very similar. He further suggests that the 

 two species may be one and the same. He separates the two on the 

 basis of the smaller size and the shorter funicle joints of E. atripes.
