HYMENOPTERA 675 



length, the first being slightly shorter than the second, both elongate and slender, the 

 antepenultimate joint of nearly the same length as these, but much stouter, about twice 

 as long as wide. The scutellar cup is elongate-ovate, its greatest width being less than 

 half its length ; its margins are not very distinct, its dorsal surface bears no punctures 

 in front of the posterior fovea, or at most one or two very feeble ones, but its sides are 

 somewhat roughened by a number of punctures. Abdominal hairy girdle not dense. 

 Length $ r75 mm. 



Hab. Hawaii, Kilauea. 



(2) Eiicoila (P.) orobates, sp. nov. 



Extremely like E. oreias, with similar long antennae, which do not differ much in 

 structure from those of that species. The legs, however, are less dark in nearly all 

 parts, brown and, where paler, yellowish, the neuration of the wings is darker, fuscous ; 

 the scutellar cup is well margined, wider, about twice as long as its greatest width, and 

 bears punctures on each side dorsally in front of the posterior fovea, its sides are quite 

 smooth, polished and impunctate or nearly. Length % 175 mm. 



Hab. Hawaii, Kilauea. 



(3) Eucoila [P.) hygropJiila, sp. nov. 



Black, polished, legs ferruginous or testaceous, hind coxae and sometimes the 

 middle ones darkish brown, the hind femora and tibiae also browner, the hind tarsi 

 dark fuscous ; several of the basal antennal joints more or less distinctly reddish. 

 Neuration fuscous, more or less yellow-tinged. Antennae considerably shorter than 

 the whole insect, without a definite club, but the fourth joint of the flagellum is 

 considerably thicker than the third, the first joint being decidedly longer than the 

 second or third, which are subequal and shorter than the fourth ; the antepenultimate 

 joint is considerably less than twice as long as its width. The scutellar cup is well 

 defined, not at all impressed, but with a distinct posterior fovea, very elongate, about 

 three times as long as wide ; the sides are finely longitudinally rugulose ; sides of the 

 propodeum and the basal abdominal girdle densely hairy. Length % i "5 — 2 mm. 



Eucoila hygrophila \'ar. pliilygra nov. 



Like the above in sculpture etc. but with the neuration yellower, and the basal 

 joints of the flagellum rather different, the first joint being slightly but distinctly longer 

 than the second, and about equal to the third. Length % i "2 mm. 



Hab. Oahu ; 1500 — 2000 ft.
