Black, the abdomen except at the base, more or less brownish or ferruginous. Antennae piceous, short and stout, the basal flagellar joints only about two times as long as thick; those beyond the middle quadrate. Metanotum regularly areolated, the basal and middle lateral areas completely separated. Basal segment of abdomen black; the second segment pale ferruginous; following growing gradually darker to the tip which is fuscous. Ovi- positor long, nearly as long as the body, but this seems to be due in great part to pressure, all the termi- nal segments being strongly ex- truded. Legs black, the knees lighter. Wings subhyaline, stigma and veins piceous; the former rather broad, subtriangular; mar- ginal cell short, the radius sharply angled, its second section straight, twice as long as the first. Areolet rather large, obliquely rhomboidal and broadly sessile above. Submedian cell very slightly longer than the median; discocubital cell shorter than usual. Described from one specimen sent by Professor Cockerell, No. A15. Type in the Amer. Mus. Nat. Hist. Mesochorus abolitus, sp. nov. (Fig. 66.). ff #v <syr Fig. 65.— Mesochorus carceratus, sp. nov. Type. ;i :;yv Sex? Length probably 8 or 10 mm. A specimen only in part preserved, but with both anterior wings in good condi- tion. The color of the head and thorax is dark, with the abdomen lighter and distinctly banded with blackish on each segment anteriorly. Antennae rather long, the joints toward the apex of the flagellum broad, quadrate or slightly transverse. The wings are hyaline, with fuscous stigma and veins; stigma lanceolate, but nevertheless rather broad, with its inferior margin distinctly angled; marginal cell long, the second section of the radius straight, less than twice as long as the first. Areolet with a long petiole,
