Sculpture a little smoother and pilosity a little shorter than in the female. Female: Forewing to mm. long; frons, upper part of prono- tum, and mesoscutum very strongly mat, without noticeable punc- tures, with appressed dense pubescence, the hair sockets of which are separated by about the length of the hairs; mesopleuron mat, without noticeable punctures, with dense appressed pubescence, the hair sockets of which are separated by about the length of the hairs; sculpture and pubescence of metapleuron and propodeum variable; second tergite mat, with dense appressed pubescence arising from weak punctures that are separated by about their diameter. Coloration of both sexes black to ochraceous, according to the subspecies. Wings of female subhyaline, the forewing somewhat infuscate basally, in a band at the level of the basal vein, in a broad area extending from the base of the stigma to the apex of the third cubital cell, and a little infuscate along the apical margin (pi. 1, fig. 10). Wings of male a little more hyaline than in the female and with the fuscous areas paler and a little less extensive. 3a. Dipogon (Dipogon) brevis recalvus, new subspecies Male: Metapleuron subpolished, with weak fine punctures sepa- rated by about their diameter; propodeum moderatelj^ mat to.
