Mesonotum and pleurae smooth. Metathorax short, declivous and obtusely rounded above. Abdomen strongly petiolate, the first segment fully one and one-half times as long as the meta- thorax, very slender at the base, and evenly expanded toward the tip; second half as long as the first and much expanded as seen in lateral view; remaining segments forming a pointed, ovate body. Ovipositor at least as long as the body and perhaps longer as its tip is not visible. Legs, more especially the posterior pair long and slender. Posterior coxae very long, reaching to be- yond the middle of the Fig. 32.— Leptobatopsis ashmeadii, sp. nov. Type. abdominal petiole, their trochanters extending to beyond its tip. Femora short and stout, the tibiae as long as the femora and trochanters together. Wings hyaline, with light colored stigma and veins; stigma lanceolate; first section of the radius only about one-third as long as the second which is recurved in conformity with the costa, making the apical part of the marginal cell long and narrow. Median and submedian cells of equal length; discoidal nervure broken distinctly below the middle; discocubital vein evenly arcuate; areolet small, rhomboidal, distinctly petiolate above. Described from one specimen collected at Station 13B by Mrs. W. P. Cockerell. Type in the Amer. Mus. Nat. Hist. This is an undoubted acoenitine, but seems to be midway between Leptobates and Leptobatopsis, the latter genus perhaps being closer. Unfortunately Ashmead's description of Leptobatopsis (Proc. U. S. Nat. Mus., 1909, 23, p. 47, is very short and the type species there desig- nated has never been described. However, the peculiar elongation of the abdomen is undoubtedly the same although the form of the areolet is mo
