452 PROCEEDINGS OF THE NATIONAL MUSEUM vol. lis 



Type locality: Arlington, Va., May 30, 1958, K. V. Krombein col- 

 lection. Paratypes collected June 4, July 3 and 6, 1955; May 26, 

 1957, by K. V. Krombein. 



Host: Unknown for the type series. Possibly Stigmus species and 

 Leperisinus aculeatus (Say). 



Distribution: United States: Virginia, New Jersey, Maryland, and 

 Illinois. 



Remarks : This species is close to Eurytoma lycti Ashmead but can 

 be separated from it by the more extensive sculpturing that covers 

 the dorsal surface of the sixth abdominal tergum, the tubercles on the 

 propodeum, and the lack of any yellow on the head.

Eurytoma lycti Ashmead, 1894, p. 325.— Elliott and Marley, 1911, pp. 452-496.— 

 Peck, 1951, p. 576. 



Types: U.S. National Museum, no. 11869. Type material consists 

 of 1 female which I have labeled and designated as type. 



Type locality: Morgantown, W. Va., bred Sept. 10, 1893, by 

 A. D. Hopkins. 



Distribution: United States: Vu-ginia, West Virginia, Kansas. 



Host: Lyctus striatus Melsh in Hickory (Ashmead, 1894). 



Remarks: The only host record for this species is Lyctus striatus 

 Melsh, nesting in Hickory, cited in the original description by Ashmead 

 (1894). It is probably rather widely distributed as the lone specimen 

 from Riley County, Kansas, suggests. 



This species is distinguished by the presence on the propodeum of 

 a very narrow but quite deep median furrow, the absence of a thin 

 scale on the dorsal surface at the anterior end of the petiole, and a 

 raised obtuse tubercle, and the absence of distinct, complete parapsidal 

 grooves on the mesonotum.
