rest of funicle joints approximately square. Legs with black to dark-

 a few. Wing veins brownish yellow; marginal vein broad, especially 

 toward distal end; postmargmal vein linear; marginal vein only 

 slightly longer, averaging .19 mm. (.17-.22) in length, than the post- 

 marginal which averages .17 mm. (.17-.20).

 Abdomen with fine sculpturing over entire surface. Legs with black

 lum with five pedicellate segments and a terminal unit of two closely 

 fused segments. Wing veins brown; marginal vein broad, averaging

Types: 49 females and 3 males. Holotype female, allotype 

 male, and paratypes in the U.S. National Museum collection (USNM 

 66060). Paratypes in Bugbee collection, Meadville, Pa. 



Type locality: Ventura County, Calif. Holotype female collected 

 Jan. 11, 1941, lot 41-594. Paratypes collected Jan. 11, 1941, lot 

 41-594, from Pleasanton, Calif. 



Distribution: United States: California, Idaho, Washington. 



Host: Bred from seeds of Ceanothus divaricatus. 



Additional host species : C. thyraifiorus, C. cordulatus, C. velutinus, 

 and C. sanguineus. 



Remarks : This new species is apparently phytophagous within the 

 seeds of several species of Ceanothus. It seems to be closely related to 

 the phytophagous seed infesting species (Eurytoma rhois Crosby and 

 E. seminis Bugbee) in sumac. The sixth abdominal tergum that is 

 longer than four and five combined, and the short stubby ninth tergum, 

 averaging .08 mm. in length will distinguish this species from E. 

 seminis, while the plump abdomen with the more extensive sculpturing 

 of the sixth tergum will separate it from E. rhois.
