150 BRITISH ICHNEUMONS. \Hemiteles. 



Common in Norfolk (Bridgman) ; bred in the middle of August from an 

 egg-bag of the house-spider, in Devon (Hignell) ; Yorkshire (Marshall) ; 

 Maldon in Essex (Fitch). I possess it from Shere, Lyndhurst, South 

 Leverton in Lines., Bristol, Felden, Ryde, Kenton, Tuddcnham Fen, and 

 house windows at Southwold and Monks' Soham, from June to November. 

 It has been bred from such widely different hosts as Epeira diadema, 

 Grapholitha tripunctana. Psyche calve/ia, Coleophora hemerobieUa, Litho- 

 colletis sfiinicolella, Lasiocampa pini through Alicrogaster sp., and the galls 

 of Cynips Kollari. Musham has bred it from an unknown host at Lincoln, 

 in June ; and Chitty captured it at Huntingfield, Kent, in October.

Hemiteles auricidatus. Thorns. O. E. x. 977 ; Schm. Term. Fiiz. 1897, p. 545, 6 9. 



A stout, black and shining species, with very uneven abdominal sculp- 

 ture. Head triangular, black, with the ungeniculate mandibles red and 

 palpi stramineous ; vertex narrow and declived, frons smooth with the 

 antenna! scrobes auriculate ; clypeus hardly discreted, apically mutic ; 

 epistoma sub-prominent and laterally obliquely sulcate. Antennae black, 

 somewhat stout and nearly as long as the body ; of 9 basally rufescent. 

 Thorax convex and nitidulous ; mesonotum centrally, sparsely and some- 

 what strongly punctate ; metathorax rugose with the areola laterally in- 

 distinct, emarginate at base and apex, and not elongate ; lateral costae 

 distinct, apophyses stout and obtuse ; petiolar area obsoletely discreted. 

 Abdomen broad and black, with the central segments transversely im- 

 pressed ; the basal strongly explanate and apically transverse, distinctly 

 aciculate and apically glabrous ; the three following segments coriaceous 

 with their apical half glabrous ; terebra rather longer than the first seg- 

 ment. Legs fulvous, usually with the coxae, trochanters, and base of the 

 $ femora, black. Wings hyaline ; fenestrae broadly separated ; stigma 

 piceous, radix and tegulae stramineous ; nervellus antefurcal. Length, 

 4-5 mm. 



This species resembles H. melanarius, but the head is smoother, the 

 cheeks longer, mesonotum more sparsely punctate with elongate notauli, 

 and the basal nervure is nearly vertical. 



It has not before been recorded from Britain. Mr. Alfred Beaumont 

 first took this Swedish species at Whitby, on i ith August, 1897, and kindly 

 presented it to me. There are also four females in Dr. Capron's collection, 

 presumably from Shere in Surrey.

1 Modern Continental authors have given priority incorrectly to the ?, presumably on account 

 of " dignity of sex " (cf. Ratz. Ichn. d. Forst. iii. 172 ; Wesni. Bui. Ac. Brux. 1853, p. 301 ; etc.) ; the S 

 name however, being the earlier, must stand. [Since this was written, I see Schmiedeknecht has 

 adopted the correct synonymy.)
