NO. 3533 CHALCID WASPS OF GENUS EURYTOMA — ^BUGBEE 485 



Type locality: Albany, Alameda County, Calif., collected May 1958 

 by L. E. Caltagirone. 



Distribution: United States: California. 



Host: Bred from gall on Salix species produced by Euura pacifica 

 (Marlatt), Burks determined, and E. resinicola (Marlatt). 



Remarks: The new species resembles Eurytoma stigmi Ashmead 

 and E. tomici Ashmead in the slightly clavate antennae and the wide 

 median furrow of the propodeum. 



49. Eurytoma tomici Ashmead

 Eurytoma lomici Ashmead, 1894, pp. 325, 326. — Taylor, 1929, p. 37. — Peck, 

 1951, p. 579. 



Types: 1 male type no, 11870, U.S. National Museum. Apparently 

 this is all the type material there is and so the 1 male specimen is 

 designated as type. 



Type locaHty: Morgantown, W. Va. 



Distribution: United States: New York, West Virginia. 



Hosts: Tomicus (—Pityogenes) plagiatus (LeConte) (Ashmead, 

 1894), Cylindrocopturus eatoni Buchanan (Peck, 1951), C. furnissi 

 Buchanan (Peck, 1951), Epiblema strenuana (Walker) (Peck, 1951). 



Additional hosts : Phloeosinus species, and Cylindrocopturus longulus 

 (LeConte) ; records U.S. National Museum. 



Remarks: Eurytoma tomici Ashmead is very close to E. stigmi 

 Ashmead. The temptation to call them one species was strong, but 

 because of the rather meager material of both species, it seems best 

 to keep them separate with the hope that adequate series with precise 

 host data will be available someday. 



In general E. tomici seems to have more black infuscation on the 

 legs, especially in the male, and less sculpturing on the surface of the 

 sixth tergum. In E. stigmi the fine scaling may extend over the dorsal 

 surface while it is Hmited to the lower one-half of the lateral surface 

 of the sixth tergum in E. tomici. 



50. Eurytoma appendigaster (Swederus)
