( 91 ) III. Australian Braconidae in the British Museum. By Rowland E. Turner, F.Z.S., F.E.S. [Read February 6th, 1918.] Subfamily BRACONINAE. Stigmatobracon, gen. no v. Scape ovate, nearly twice as long as the greatest breadth, antennae as long as the whole inseet or longer. Head transverse, eyes moderately large. Parapsidal furrows shallow, but distinct. Abdomen longer than the head and thorax, parallel sided, rather elongate; first tergite much longer than broad, with a deep longi-tudinal groove on each side; second tergite without a median area, with a deep oblique groove on each side from the base to the apical angles, the grooves nearer to each other at the base than to the anterior angles, the segment as long as its apical breadth; second suture feebly crenulate ; the whole abdomen smooth and shining, the sutures, except the second, shallow and smooth. Terebra short and very stout, not more than one-third of the length of the abdomen, slightly curved downwards, the valvulae broad, especially at the apex and pubescent. Sternites 1-4 longitudinally earinate in the middle; the fifth sternite large, with a median longitudinal sulcus, narrowly emarginate at the apex and projecting much be-yond the apex of the abdomen, so that the terebra has the appear-ance of originating on the dorsal surface instead of ventral. Third tergite with the basal angles only very indistinctly divided from the rest of the segment. Nervulus interstitial; first abscissa of the cubitus almost straight; first discoidal cell almost as high at the apex as at the base; stigma large, the radius originating before l he middle; first abscissa of the radius very short, second very long; radial cell almost reaching the apex of the wing. Hind and inter-mediate tarsi no longer than the tibiae. KEY TO THE SPECIES. 1. Stigma yellow. 2. Stigma black, with a very small yellow spot at the base S. torresensis, Turn. 2.
