longer than the pedicel, the first ioint of flagelkim only slightly 

 longer than the second, about three times as long as thick, the 

 third very httle shorter than the second, the fourth and following 

 joints increasing in length to the seventh, joints S, 9, and 10 sub- 

 equal, only a little shorter than the eighth, the last ovate, scarcely 

 longer than the penultimate. Cup of scutellum narrowed ovate, 

 produced into a carina anteriorly, its disk with a single small 

 fovea or puncture. "Wings hyaline, ciliate, the veins yellowish, 

 the marginal cell closed, a little more than l^ times longer than 

 wide, the second branch of radius slightly the longest. Abdomen

(9) EUCOELA NIGMCBPS, Sp. n. 



(S . Length 1*6 mm. Coloured as in preceding species (^. atriceps), 

 hut much larger; the antennae 15-joiuted, long, filiform, nearly 

 twice the length of body, dusky only toward tips ; the joints of 

 flageUum all long, cylindrical, but very imperceptibly shortening, 

 the last being the shortest and only about two-thirds the length 

 of the first, the first scarcely longer than second; the pedicel 

 rounded, not longer than thick ; the scape subglobose, very little 

 longer than thick. Cup of scutellum large, oval, with a transverse 

 fovea posteriorly, the smooth anterior part with about four small 

 punctures. Wings hyaline, ciliate, the veins yellowish, the 

 marginal cell closed, about twice as long as wide, the second 

 abscissa of radius being If times as long as the first. 



Mount Gay Estate. Described from one male specimen. 

 Although closely resembling E. atriceps in colour, it cannot possibly 

 be the opposite sex of that species, since it is larger, has a dif- 

 ferent shaped scutellar cup, and a much longer marginal cell.

 the antennae are a little shorter, with the joints of the flagellum of 

 an equal length, the first being slightly curved or bent, when 

 viewed from the side, while the cup of the scutellum is broadly 

 oval, its fovea posteriorly transversely oval and very shallow. 

 Wings as in previous species.

Antennae 13-jointed, subclavate, submoniliform, the first joint of 

 flagellum obconic, twice as long as the second, which is only a little 

 longer than thick, joint 3 a little longer than the second, joint 4 

 longer than third and thicker, the joints beyond submoniliform, a
