. Bulletin of the Museum of Comparative Zoology at Harvard College. Zoology; Zoology. BRUES: NEW PHYTOPHAGOUS HYMENOPTEKA. 265 a recurrent nervure. Antennae stout and thick, and possibly with the last joint long, as in Argc and its allies. However, this character is not very plainly to be seen on the specimen. I have not been able to locate this specimen with any degree of satisfaction. The similarity of the antennae to those of Arge et al. is very striking, but it is possible that the last joint is in reality several closely united ones. From these forms it differs at once by the non-appendiculate marginal cell and the divided anal cell. The absence of the first transverse cubitus reminds one of Emphytus, but the position of the first recurrent nervure is entirely different. Paremphytus ostentus, sp. nov. Female. Length 9 mm. Elongate, black, with indications of brownish bands on the abdomen. Head very small, considerably narrower than the thorax and about one-half as thick as wide. Abdomen with nearly parallel sides; obtusely rounded at the tip where the terebra projects quite distinctly. Wings distinctly infuscated, especially on the apical half. Marginal cell long, divided, gradually narrowed to the tip, which is rounded but not appendiculate. First submarginal. Fig. 6. — Paremphytus ostentus Brues. Fore-wing. cell very long, as long as the second along the radial nervure; second submargi- nal strongly widened, so that the second transverse cubitus is twice as long as the first. Submedian cell much longer than the median, the basal nervure and the transverse median vein separated on the median vein by a distance almost as great as the length of the basal nervure. Anal cell with an oblique cross-vein. Type-. — No. 2042, Mus. Comp. ZooL, Florissant, Col. (No. 11,586, S. H. Scudder Coll.). Pseudosiobla Ashmead. Cockerell ('07) has described a single species from Florissant. There are none in the material at hand. Taxonus Hartig. Two species of Tertiary saw-flie
