Genus: Copidosoma Ratzeburg (1844). Copidosoma tortricis sp. n. Distinguished by the proportions and chaetotaxy of the antennae (<£, $) (Fig. 3 a, b) especially by the short second funicular joint (o*); the proportions of the head (Fig. 2 b); labrum (Fig. 2 c); and radius (Fig. 5). The colour ot the antennae is probably also of importance. Note. The proportions of the antennal joints must be studied in properly pre- pared mounts. In naturally dried specimens there is considerable distortion and the club ($) in particular is liable to appear unduly flattened. The filamentous end of the preapical dorsal mandibular bristle (Fig. 2 a) is often broken Fig. 2. Copidosoma tortricis Wtrst. ?. (a) right mandible from inside, (b) head from in front, (c) labrum. A dark blackish brown species in both sexes, with metallic reflections on head and thorax and submetallic on the abdomen dorsally. $. Reflections variable but mainly as follows. On face, frons, vertex, pronotum and scutum mainly dark green or aeneous green; on scutellum and mesopleurae (more shining) and abdomen (more dully) purplish. Outer aspect of hind coxa submetallic. Antennae concolorous, blackish brown. Palpi paler than rest of trophi. Wings sub-hyaline very faintly and uniformly tinted; neuration brownish, indistinctly and shortly clouded at the base of the radius distally. Legs all tarsi paler, fore and hind coxae, trochanters, femora (except the extreme apex), tibiae (except for a narrow basal ring and in the fore pair sometimes the tip obscurely) blackish—the excepted portions paler. In the mid legs the coxa is dark, trochanter, base of tibia (narrow
