132 BRITISH ICHNEUMONS. [Hemiteks. 



with the alutaceous second and third segments, and apex of the first, 

 red ; basal segment aciculate-punctate, explanate throughout with carinae 

 indistinct and spiracles prominent ; segments four to seven shining and 

 the terehra hardly shorter than the abdomen. Legs red, with tbe coxae, 

 trochanters, apices of femora, tibiae and the hind tarsi, piceous. Wings 

 of 9 with two broad piceous fasciae ; radix and base of tlie stigma white, 

 tegulae fulvous. Length, 6-7 mm. 



Thomson says his species very closely resembles H. areator and H. bico- 

 lorinus ; the $ differs from the former in having the head entirely black, 

 the wing-fascia broader and the terebra longer ; the $ is coloured like 

 H. bico/oriniis, but the large ocelli and superiorly strongly narrowed face 

 will serve to distinguish it, though this sex is, perhaps, not the same as 

 that described by Brischke. This species, like H. areator^ differs from 

 H. hicolormus in having a regular, though externally incomplete, areolet 

 and the epipleurae of the second and third segments are acute. 



It is very difficult to synonymize the species founded l)y Thomson on 

 characters referred to by no other author, but the descriptions of H. fascii- 

 pennis and lon^icauda tally so exactly in every mentioned particular that, 

 as tentatively suggested by Schmiedeknecht, and especially on the evidence 

 of the terebra, I feel justified in uniting them here. The divergence of 

 size is one of small consideration in the present genus. 



Bridgman found a female of this species among insects taken by 

 C. W. Dale ; he adds that in this example the first segment, part of the 

 second, and nearly the whole of the legs were red ; the latter took two 

 specimens at Bournemouth in April, 1867 (cf. E.M.M. 1890, p. 24). 

 Brischke bred his species from spiders' nests and Microgas/er cocoons in 

 Prussia, whence its range extends to Sweden.

Head of c^ usually black, with the ocelli large and eyes approximating; 

 of ? with the face mainly red, either with the internal and external orbits 

 red and confluent occipitally, or with the discreted clypeus and a central 

 facial dot black ; mandibles centrally fulvous, palpi stramineous. Antennae 

 filiform, ferrugineous and becoming apically infuscate, with the scape 

 paler. Thorax black, with the prothorax and two mesonotal vittae red ; 

 of $ red, with the metathorax dorsally black ; metathorax closely punctate, 

 with short rugosities along the costae ; areola more or less distinct. Scu- 

 tellum entirely or ai)ically red. Abdomen ovate, as broad as the thorax, 

 dull and closely punctate ; basal segments with the margins more or less 

 broadly, the second sometimes mainly, red ; basal segment of the $ 

 gradually dilated apically, twice longer than broad ; post-petiole of S 

 parallel-sided and nearly twice broader than the i)etiole ; terebra not much 

 longer than the first segment. Legs red with the trochanters and femora 

 sometimes infuscate above ; anterior tibiae usually, hind ones always, 

 basally white, the latter rarely externally nigrescent. Wings hyaline, of $ 

 with traces of two infuscate fasciae ; of ? with three dark fasciae, two
