NO. 3533 CHALCID WASPS OF GENUS EURYTOMA — BUGBEE 475 



safe to assume that the type material of this species may have come 

 from the same area. 



Distribution: United States: Kansas, southern Illinois and Indiana 

 to Maryland, south to South Carolina and Mississippi, and west to 

 Texas. 



Host: Walsh (1870) lists his specimens as having been bred "from 

 the Cynipidous oak-gall Q. prunus, Walsh," which appears to be 

 Amphibolips prunus (Walsh) that occurs on various Red Oak species. 

 A. gainsei Bassett and Callirhytis seminator (Harris). 



Remarks : There does not seem to be any basis by which E. prunicola 

 globulicola Walsh can be distinguished from E. prunicola Walsh. 

 The considerable variation in the reddish-brown coloration of the 

 specimens examined, on which the redescription is based, ranges from 

 abdomens that are all black, except the long sixth segment, to those 

 that are all reddish brown, except for some black infuscation on the 

 dorsal surface of segments three to five. Walsh distinguishes E. 

 p. globulicola from E. prunicola because of the former's reddish- 

 brown (rufous) abdomen. 



E. prunicola appears to be closest to E. querci-globuli. The reddish- 

 brown coloration is much the same, and, as in E. querci-globuli, the 

 color variation ranges from predominately black in some of the more 

 northern populations (Indiana and Illinois) , to predominately reddish 

 brown in the southern material (Bonneau, S.C.). It differs, however, 

 in the oval abdomen with less lateral compression, longer sixth abdom- 

 inal segment, shorter ninth tergum, less posterior extension of the 

 ventral valves of the female genitalia, less extensive sculpturing on the 

 lateral surface of the sixth abdominal segment, a stouter, broader 

 marginal vein, and a short postmarginal vein in relation to the 

 marginal. 



The redescription is based on the types in the U.S. National 

 Museum collection and the considerable number of specimens in the 

 author's collection.
