HYMENOPTERA PARASITICA 309 



(2) Toxcmiia fcrrugineipes, sp. nov. 



%. Length 2*8 mm. Head and thorax aeneous-black, the frons more distinctly 

 metallic, the antennae black, the scape beneath towards base and the legs, except the 

 hind coxae, ferruginous ; wings hyaline, the veins brownish-yellow. 



The antennae are much longer than in the preceding species [hawaiiensis), all 

 the funicle joints being distinctly longer than thick, the first being fully twice as long 

 as thick, the following to the club gradually shortening. The metathorax is slightly 

 produced medially at apex, with a strong, sharp median carina, and has the pleural 

 ridges ciliate with long white hairs. The marginal and postmarginal veins are long, 

 as in the previous species, but the stigmal is somewhat longer, being nearly two-thirds 

 the length of the postmarginal vein. The abdomen, seen from above, is long, conic- 

 ovate, while beneath towards the base it is produced into a large triangular keel. 



Hab. Molokai, in mountains (4800 feet), in August. — Hawaii : Kilauea in August. 

 — Maui: Haleakala (7000 — loooo feet), in May. 



(3) Toxeuma affinis, sp. nov. 



$. Length 2 '6 mm. Head and thorax above bronzed green, feebly shagreened, 

 the thorax at sides and beneath, the co.xae and the abdomen aeneous-black ; femora 

 brown-black, the hind pair submetallic, the trochanters, tibiae and tarsi, except last 

 joint, ferruginous or brownish-yellow. 



The antennae are shorter than in T. fernigineipes, with all the funicle joints wider 

 than long, cup-shaped. The metathorax has the lateral carinae strongly curved inwardly 

 towards apex, with the median carina short. The wings are hyaline, with a subfuscous 

 cloud beneath the stigmal vein, the veins being dark brown ; the postmarginal vein 

 is almost as long as the long marginal, while the stigmal vein is about two-thirds the 

 length of the postmarginal. 



$. Length r6 to r8 mm. Head and thorax darker than in ?, or bronzy-black, 

 the abdomen oblong-oval, briefly petiolate, the antennae filiform, the flagellum with 

 long, sparse hairs, the funicle 7-jointed, the joints elliptic-oval, longer than thick, the 

 legs, except the hind coxae, brownish-piceous, the sutures of the joints and the tarsi 

 yellowish ; otherwise as in the ?. 



Hab. Kauai (4000 feet), in October. — Lanai (3000 feet), in January. — Molokai 

 Mts. (4500 feet), in September.

 (Plate VHI. fig. 6, ?.)
