28. Toryinus aiithoniyiae n. sp.— 9. Length .07 inch. Ovip. .05 inch. 

 This is another short, robust, nietallic-green species, closely resembling Synto- 

 maspis tubicola O. S., and difficult to distinguish from it. In color it is exactly 

 the same, excepting the femora at tips, and the tibiae, and tarsi are pale yellowish ; 

 the ovipositor is shorter and stouter and the abdomen is pubescent. These char- 

 acters will also distinguish it from Tort/mns omnivorse m. 



Described from two specimens taken on a cultivated j)laut, the 

 leaves of which were mined by an anthomyid larva which I have 

 good rea^sons for suspecting is parasitized by this species. 



ORxTIYRUS Westwood. 



29. Ormyrus vacciiiiifola n. sp.— 9 . Length .10 to .12 inch. Blue- 

 black, with a slight metallic lustre and the thorax almost devoid of the peculiar, 

 fine, wrinkled sculpture, so characteristic of this genus. The head is finely 

 transversely rugulose ; the antennaj dark brown, scape rufous ; the legs pale 

 brown with a reddish cast, the posterior femora being slightly iufuscated above, 

 all coxie brown, excepting the posterior ones at base. The abdomen is much 

 compressed, brown, with a metallic lustre, a row of long white hairs on each seg- 

 ment, excepting the basal one, and the tip is prolonged into a slender point. The 

 wings are hyaline and the veins brown. 



Hah. — Toronto, Canada. Described from three specimens sent by 

 Mr. Wm. Brodie, and reared from the cynipidous gall Solenozopheria 

 vaccin'd Ashm. 



The compressed abdomen and its color will separate this species 

 from the others in our fauna. 



30. Ormyriis veiitricosus n. sp. — %, . Length .1.5 inch. A robust form 

 of a uniform aineous-green or dark greenish-blue color including the legs and 

 the antennal scape. The abdomen is bluish-green above ; the anterior tarsal 

 joints are streaked above with brown and the four terminal joints of the middle 

 legs are brown, the basal joint being yellowish-white, or sometimes all the tarsal 

 joints are whitish and the legs greenish-blue. 



Hub. — Toronto, Canada. Described from specimens reared from 

 Andricus ventricosus B., and an undescribed oak gall sent by INlr. 

 Brodie. 



.31. Oriiiyrus iiiiiiutus n. sp. — % J. Length .04 to .08 inch. Color 

 ranging from metallic-blue through greenish-blue to bluish-green, with rufous 

 legs ; the femora are generally green or blue, sometimes brown, the posterior ones 

 being much thickened, sometimes all the femora are rufous, the same color as the 

 tibiae ; sometimes only the posterior femora will be green or blue, and sometimes 

 the tibite, especially the i)osterior pair, will be rufous: one % has uniform brown- 

 ish-yellow legs. 



Described from numerous specimens reared from oak gall Neuro- 

 terus luurifolke Ashm. 



Like Ormyrus labotus Walker, it is very variable, but the thick- 

 ened thio-hs will readilv distinuuish it.
