NO. 3533 CHALCID WASPS OF GENUS EURYTOMA — BUGBEE 489 



only, leaving dorsal surface smooth and shiny. Propodeum may have 

 a complete wide median furrow that maintains same width from top 

 to bottom. Wing vein relationships and color of the legs same as 

 in the female. 



Types: 6 females and 1 male. Holotype female in the U.S. Na- 

 tional Museum (USNM 66058); paratypcs in Bugbee collection, 

 Allegheny College, Meadville, Pa. 



Type locality: Gosport, Ind. Holotype collected on Mar. 28, 

 1933; emerged May 30, 1933. Paratypes collected on Mar. 28 and 

 Apr. 3, 1933; emerged May 30 and June 1, 1933. 



Host: Bred from dipterous gall on Ragweed (Ambrosia species). 

 The gallmaker is believed to be a species of Trypetidae. 



Additional hosts records include Trypeta { = CaUachna) gibba Loew, 

 and T. (=Aciunna) notata Coquillett. 



Distribution: Eastern half of the United States, from Illinois, Ohio, 

 and Indiana, south to Louisiana and west to Texas and New Mexico. 



Remarks : The most likely hosts of this new species seem to be dip- 

 terous gallmakers of the family Trypetidae and Ortalidae. 



This species differs from E. tylodermatis and E. pini in having a 

 broader, shallow, concave propodeum with a wider median furrow that 

 is indicated dorsally only ; in other specimens the median furrow may be 

 lacking entirely, and the surface may be covered with fine, even punc- 

 tations dorsally and irregular horizontal ridges ventrally; postmar- 

 ginal vein is usually longer or equal in length to the marginal, seldom 

 shorter; the extensive reticulation of the abdominal segments, es- 

 pecially the sixth, which may be completely covered or reduced to a 

 narrow band on the anterior half of the dorsal surface.

 Eurytoma terrea Bugbee, 1951, pp. 23S-240.— Burks, 1958, p. 82. 



Types: 7 females. Holotype female in the U.S. National Museum. 

 Paratypes in the Bugbee collection, Meadville, Pa. 



Type locality : Ashland, Oreg. 



Distribution: Oregon. 



Host: Diplolepis polita (Ashmead) var. on Rosa species. 



Remarks: Additional characteristics that will help to define this 

 species include: black tegula and scape; black infuscation on femora 

 and tibiae of all legs; broad dorsal valves of the female genitalia that 

 turn dorsally, anteriorly, only slightly with ventral valves, so that 

 stylet arch is in a horizontal plane.
