Specimen partly seen in ventral view, the head greatly widened behind; the large, externally arcuate mandible on one side showing very distinctly. Body behind the scutellum showing the dorsal view (i. e. the specimen split off to the dorsal wall). Metathorax distinctly rugose-reticulate. Abdomen as long as the head and thorax together; subpetiolate; first seg- ment gradually widened from the base to the apex which is a little less than one-half as wide as long. Second segment as long as the first, but much wider than long; follow- ing together as long as the first two; apex obtusely pointed. Ovi- positor preserved to a distance nearly equal to the length of the abdomen and possibly still longer. Legs moderately slender. Wings long and rather narrow, stigma and veins fus- cous, the former short and broad, subtriangular. Radial cell long, almost attaining the wing tip, the first section of the radius less than one-half as long as the second. Three cubital cells, the second short, its inner side one-half longer than its upper. Recurrent nervure interstitial with the transverse cubitus; submedian cell as long as the median; discoidal nervure broken below the Fig. 73.— Alysia petrina, sp. nov. Type.
