HYMENOPTERA 653 



margins of the eyes, the latter hairy. Scape of antennae somewhat dilated on the 

 apical part beneath, pedicel obconical, elongate, considerably longer than the first joint 

 of the funicle, the latter not differing much in length, the apical ones appearing some- 

 what shorter than the basal, club with three subequal joints and about as long as the 

 three preceding joints together. Thorax densely sculptured, the sculpture, which 

 appears to be a close shagreening, more or less concealed by the conspicuous clothing 

 of short white pubescence. Marginal vein subpunctiform, postmarginal very little 

 developed, stigmal shortish. Hairless, oblique line very distinct, rest of wing closely 

 and regularly set with hairs. Length 1-5 mm. Ovipositor very little prominent. 

 Female. 



Hab. Hawaii, Kilauea. 



(2) Anagyrus xanthogaster, sp. nov. 



Very litce the preceding, but in its typical form smaller, the antennae shorter and 

 very differently coloured, the general appearance being sordid yellowish, the apical 

 joints darker, but without the strongly contrasted coloration of A. major. The abdomen 

 yellow above. 



On Oahu I have found a larger form, not apparently differing in structure from the 

 above, the mesonotum is reddish brown, the face nearly entirely pale yellow. 



Hab. Hawaii, Kilauea ; Oahu, on the coast. 



(3) Atiagyrus nigricans, sp. nov. 



Black, the legs yellow, the hind femora and tibiae slightly clouded. Wings hyaline 

 but not quite clear. 



Head dull, with fine feeble and not dense puncturation ; antennae pale-tinted, not 

 quite black, with the scape subdilated beneath, the pedicel obconical about as long as 

 the first funiclar joint, which is much longer than wide, the following joints not differing 

 much in length, all being more or less elongate, the club longer than the two preceding 

 together. Mesonotum and scutellum slightly shining, very finely, remotely punctured. 

 Abdomen triangular, acute at ape.x, deeply concave in dry specimens, and more or 

 less pallid in the concavity. Neuration etc. as in the preceding. Length rather more 

 than I mm. Female. 



Hab. Oahu, near Honolulu, 1500 ft. 



(4) Anagyrus fraternus, sp. nov. 



Very similar to A. nigricans, but the scape of the antennae is very little dilated, 

 though somewhat thickened towards the apex, and the thoracic puncturation is rather 

 more distinct and the punctures more numerous on the scutellum. The hind femora
