760 MB. W. H. ASHMEAD — REPORT ON THE PARASITIC [NoV. 19, 



little longer than thick ; cup of scutellum large, hroadly oval, 

 smooth and polished, with a single round fovea on posterior part. 

 "Wings hyaline, ciliate, the venation yellowish, the marginal cell 

 open along the fore margin, nearly tx^ace as long as wide, the 

 second ahscissa of radius about 1| times as long as the first 

 and slightly curved outwardly. Abdomen black, with a narrow 

 pubescent girdle at base. 



The (S differs only in having IS-jointed, brown-black antennae, 

 with the two basal joints rufous. All the joints of the flageUum 

 are about equal in length, striated, about .3| times as long as 

 thick ; while the rounded fovea on the cup of scutellum is a little 

 larger. 



Balthazar and Mount Gay Estate. Described from one male 

 and one female specimen. 



Heptamerocera, Ashmead, g. n. 

 (Type, H. robusta.) 



Antennas in $ 13-jointed, shorter than the body, terminating 

 in an abrupt 7-jointed club. Scutellum closely punctate or rugose, 

 the cup oval or ovate, with a small fovea posteriorly. Front 

 wings with the marginal cell either open or closed, the first 

 abscissa of radius shorter than the second, the cubitus entirely 

 absent. Abdomen with the usual hair-fringe or girdle at base. 



In having a 7-jointed antennal club, this genus approaches 

 nearest to Rhoptromeris, Forster, but it is readily separated from 

 it by the first abscissa of radius being shorter than the second and 

 by the first joint of the flagellum being longer than the second. 

 Erom Heptameris, Forster, which also has a 7-jointed club, it is 

 distinguished by the great difference noticeable in the shape of 

 the marginal cell, the sculpture of the scutellum, and by the shape 

 of the scutellar cup.
