Show 1895.] HYMENOPTERA OF THE ISLAND OF GRENADA. 775 the cup oval or ovate, rarely small, elliptic, and usually with a fovea posteriorly and some punctures anteriorly. Front wings either with an open or closed marginal cell, the first abscissa shorter than the second, the cubitus wanting; apex of wings usually entire, rarely emarginate or sinuate. Abdomen with the usual hair-fringe at base. In having a 5-jointed antennal club this genus agrees with Pentacrita, Forster, a subgenus of Kleidotoma, but it is readily distinguished from it by the finely rugose or punctate scutellum, the cup being larger and the abdomen shorter, besides a difference in venation. From Cothanaspis, which also has a 5-jointed club, it is readily separated by a raised pubescent or woolly girdle at base. The genus is in reality a subgenus of Eucoela, Westwood. The species described under the new genus may be tabulated as follows:- Table of Species. Females. Marginal cell more or less open along the fore margin. 4. Marginal cell closed. Apex of front wings more or less emarginate 3. Apex of front wings entire. First abscissa of radius normal, not angulated... 2.

Cup of scutellum ovate, with a small fovea posteriorly and 4 punctures anteriorly P. distinguenda, sp. n. All coxas and legs reddish or brownish yellow. Antennas black or brown-black.
