Wien, 1859, 362; Adler, Zeits. wiss. Zool., xxxi, 197, pi. xi, fig 18; Licht., Cyn., 61, pi. ii, fig. 18. Trigonaspis renum, Mayr, Europ. Cyn., 31. Agamic Form.--Apterous, yellowish-red, the abdomen darker, with the legs paler than the body; thorax punctured, opaque, abdomen shining; the vertex finely shagreened. Antennae 13-jointed, the last joint twice the length of the penultimate; claws simple, dilated at the base. Length 15 mm. The only other European species is B. synasjris, Htg., which may be known from ours by the claws being cleft, and by the antennae having 14 joints. Gall.--Small, 1--2 mm., irregularly kidney-shaped, greenish yellow, sometimes reddish; soft, succulent, usually crowded together along the nervures. Length 2 to 3 mm. Found in the autumn, falling when ripe. The insects are very difficult to rear, and are very irregular in the length of time which they take to reach maturity. As Giraud has pointed out (l. a), the galls inhabited by the gall-maker become black, regular and ovoid in shape; while those tenanted by parasites retain the irregular shape and the fresh colour. The only British inquiline is Synergus thaumacera, but on the Continent S. varius, Htg., has been bred by Mayr; S. vulgaris by Giraud; Hartig mentions S. tibialis, Htg., as having been reared by him, and Brischke S. ruficomis and S. pallicornis. Giraud bred Mesopolobus fasciiventris, West., Gallimome fuscicrns, Gir., and von Schlechtendal a $ Torymus. Brischke records Pteromalus Saxesenii, Pleurotropis cyrriphidum, and Mesopolobus fasciiventris. Sexual Form.--Black, very shining; the abdomen bright reddishye...
