270 HYMENOPTERA. 



impunctate ; the apical half strongly punctured, except at the apex, which is shining 

 and impunctate; the rest of the abdomen closely punctured, the punctuation finer 

 towards the apex. Tips of the tarsi blackish; coxae shining, impunctate. Areolet 

 sharply angled where the recurrent nervure is received a little beyond the middle. 



EPIMECIS. 



Epimecis, Brulle, Hist. Nat. Ins. Hym^n. iv. p. 112. 



The chief distinctive characters of this genus consist in the greatly elongated pro- 

 thorax, the head being narrower behind so as to fit into it, the head here being wider 

 than the collar and provided with a distinct raised border ; the eyes are large, lateral, 

 projecting, incised at the antennae, above almost touching the ocelli, below nearly 

 reaching to the mandibles ; the ocelli large, oval, and placed on the extreme summit 

 of the head ; the mesonotal sutures moderately deep ; the abdomen much more than 

 double the length of the thorax, narrow, becoming gradually wider towards the apex, 

 with a depression on each side of the first four segments ; there is no areolet, and the 

 spurs are simple. 



The elongated collar, the eyes reaching to the base of the mandibles, and the exist- 

 ence of depressions at the sides of the abdominal segments sufficiently distinguish this 

 genus from Pimpla.

Antennae as long as the body, inclining to brownish on the lower side, covered with 

 a microscopic pile; scape with longish hair; the joints a little produced at the apices; 

 third joint nearly one fourth longer than the fourth. Head shining, impunctate ; 

 face bluntly keeled ; clypeus projecting and clearly separated ; palpi dark testaceous. 

 Thorax shining, impunctate ; scutellum gibbous ; an indistinct furrow in the centre of 

 the basal half of the metathorax. Abdomen shining, impunctate ; a tubercle at the 

 base of the four basal segments ; apex pilose, punctured laterally ; cerci longish, hairy. 

 Legs densely pilose. In the fore wings the middle cloud ends at the base of the 

 stigma, and that in the hind wings is immediately opposite it ; the apical cloud in the 

 fore wings commences a little beyond the recurrent nervure.
