NO. 3533 CHALCID WASPS OF GENUS EURYTOMA — BUGBEE 477 



Type locality: Kent Island, Md. Specimens collected Feb. 8, 1953, 

 and emerged Mar. 3, 1953. 



Host: Bred from galls of Protaplonx species on Baccharis helmifolia. 



Remarks: The male antenna of this new species has only four 

 pedicellate segments in the flagellum. The fifth is separated from 

 the two closely fused terminal units by an annulation rather than a 

 short pedicle. The lack of yellow or reddish brown on the head, 

 thorax, and abdomen will distinguish this species from Eurytoma 

 juniperinus or E. prunicola.

Types: Department of Agriculture, Ottawa, Canada, 1 female with 

 three labels. First label reads: "Type, E. nigricoxa Provancher no. 

 2513." Second label reads: "£". nigricoxa Provancher, Type 739."

Type locality: Ottawa, Canada. 



Distribution: Canada: Quebec, British Columbia, and Manitoba. 



Host: Rose galls and Periclistus species (specimens in Department 

 of Agriculture collection, Ottawa, Canada). 



Remarks: This species superficially resembles E. studiosa Say, but 

 the thorax is more robust and the propodeum is broad and shallowly 

 concave without a clearly defined median groove. It differs also in 

 the equal length of the marginal and postmarginal veins.

 lot 509, specimen 20, 1 male, paratype. 



Type locality: Stevens Creek (Santa Clara County), Calif. Col- 

 lected Nov. 24, 1906. The type female emerged Mar. 6, 1907, and

Host: Acraspis guadaloupensis (Fidlaway) on Q. chrysolepis (Fulla- 

 way, 1912) Andricus lasius (Ashmead) (Fidlaway, 1912). 



Remarks: The type female seems close to E. californica Ashmead, 

 but it is smaller in all its measurements; has more black infuscation 

 on the legs (not in blotches as in E. calijoi^nica) ; brown rather than 

 yellow tegulae, and the abdomen is not deeply oval but more 

 rectangular in shape in a lateral view.
