NORTH AMERICAN HYMENOPTERA. 195 



55. Eiirytoina jiitiidiosii Say. 



Syn. Eurytoma lanalie Fitch. 



Eurytoma phytes Walk. 



Eurytoma teredon Walk. 



? Eurytoma Bolteri Riley. 

 I have followed Walsh in considering Eurytoma Bolteri Kiley, 

 synonymous with this species, but it seems to be a much larger and 

 distinct species, and I am inclined to believe it distinct, but cannot 

 surely tell without seeing specimens. Mr. Howard's Eurytoma fune- 

 bris seems also to be closely related to studiosa ; I can find no char- 

 acter in his description to separate them. Mr. Walker's description 

 of E. phytes and E. teredon agree, and Dr. Fitch's E. lanuke is cer- 

 tainly dudiosa, for I have reared it from the same oak gall from 

 which his type came, and besides his description can only apply to 

 this species. I have reared it from several galls. 



56. Eiiryfoina inaeiilipes Aslim. 



This species was described by me as a Deeatoma ; it is a much more 

 slender form than E. studiosa, the abdomen is twice as long as thick 

 through vertically and the ventral valve is not prolonged to a point. 

 Two specimens agreeing very closely with my type were received 

 from Canada. 



57. Eurytoma calilbrnica n. sp.— 'J, 9- Length .12 to .20 inch. Black, 

 robust, similar in fuiin to Eurytoma obttisiloba Ashm. Like E. auriceps Walsh, the 

 face is covered with a golden pubescence, becoming in the female a dirty white, 

 or white on the thorax and abdomen, in the males brownish ; the abdomen, too, 

 is sia)ilar to that species in shape, but the fifth and following segments are fringed 

 with white hairs, and all the femora in the middle and all the tibite, excepting 

 sometimes the anterior pair are brown or black in the middle. The posterior 

 cos'fe are always black, but the others are generally brown. The antennae in the 

 female are 9-jointed ; in the males but 8-jointed, the 9th not being distinctly 

 separated, the first flagellar joint is very large and broad, and the others are 

 gradually narrowed, with whorls of long hairs, the terminal joint is equal in 

 length with the third. The wings are hyaline, the veins thick and of a brown 

 color; the stigmal vein is short, about half the length of the marginal vein. 



Hab. — Los Angeles, California. Described from several s])ecimens 

 reared from the oak gall Andricus pomiformis Bass. 



This species could only be confounded with E. auriceps Walsh, but 

 its large size, color of the legs and antennal characters will at once 

 separate it. 



58. Eurytoma NCuIpta n. sp.— 9- Length .12 inch. In this species the 

 abdomen is short, stout, not compressed or but slightly, nearly as broad vertically 

 or when viewed from the side as long, with ventral valve pointed and long, the 

 whole surface is sculptured and the fifth at sides and following segments |)ubes- 

 cent. The jmsterior femora are brown or black. 



Described from four specimens. This s])ecies approaches nearest 

 to Evrytoma punctiventrix Walsh.
