2 Parasite of Strawberry Tortrix 



it well, having reared a practically identical form from a Tortrix sp. in 

 Italy. As Prof. Silvestri tells me he has found this Copidosoma to be 

 polyembryonic in Italy I have no doubt the British form is so too. 



Superfamily: CHALCIDOIDEA. 



Family: Encyrtidae. 



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 off. 



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 (narrowly) 

 and apex (more broadly) paler. The main portion of the mid femur is brown, not 

 nearly so dark as the fore or hind femora. Mid tibiae variable — as pale as the fore 

 tarsus with an indistinct darker dorsal streak. 



o* similar to the $ in colour but with definitely darker legs in which the knees, 

 tarsi and sometimes the apex of the fore tibia (obscurely) alone are paler.
