Ephtalles.] BRITISH ICHNEUMONS. 39 



I have seen others captured at Rannoch by Porritt and Qrton, in Cumber- 

 land, by Day at the beginnin^r of July. It has been bred from Saperda 

 popuhiea, bv I'houless, in Norfolk (Bridgman) ; and captured at Plym 

 Bridge, in Devon, early in June (Bignell). Giraud has also bred it fron: 

 ^. popuhiea in France and Brischke from the larva of Scsia sphegiformis in 

 Prussia. Ratzeburg tells us (Ichn. d. Forst. ii. loo) that a single specimen 

 was bred at the end of July at Hohenheim from a Weymouth pine, in 

 which Ciirculio pini (ahutis, L.) had lived ; it had apparently emerged from 

 an elongate cocoon, presumably of its own construction. He adds 

 {Lc. iii. 250) that it was also raised from a species of Cerambycid, probably 

 Leiopiis fennicus, Payk., and (I.e. ii. 90) that Pimpla Reissigii was bred by 

 Reissig from alder, in which Crvpiorhynchus lapathi lived. Schmiede- 

 knecht gives 7?//(7^////;/ mnrdax, Psilura monaeha and the \ery small Hypono- 

 meufa cogna fella as alternative hosts. In the National Collection is a 

 female taken bv W. R. C. Grant at Glendole, in Forfarshire, early in 

 September, iSg'S. Buckler tells us that it has also been bred in Britain 

 from Tiochilium evnipifonne \>\ Abbott. 



4. heteropus, Thorns. 

 Ephialtes heteropus. Thorns. O. E. xii. 1249; Schra. Opusc. Ichn. 1129, ? 



A large, sublinear black species with pale stigma and very distinct 

 tubercles. Head black, with the palpi infuscate and the clypeus rufescent ; 

 vertex broad and strongly nitidulous, with a few fine and scattered punc- 

 tures ; occiput broad, bordered and hardly emarginate ; face nitidulous 

 and subdeplanate, with strong and sparse punctures ; clypeus semicircularly 

 depressed centrally and produced into a truncate tooth on either side ; 

 mandibles stout. Antennae filiform and obsoletely pilose throughout, 

 about half the length of the body and consisting of 38 joints in the 

 flagellum. Thorax immaculate ; notauli not reaching the centre of the 

 nitidulous mesonotum ; epicnemia entire, mesopleurae somewhat closely 

 and finely punctate, with the lateral sulci large and their region entirely 

 glabrous, sternauli wanting ; metathorax scabrous with the pleurae hardly 

 smoother, its disc indistinctly bicarinate with the carinae indeterminately 

 divergent apically ; spiracles subcircular. Scutellum black, subconvex, 

 shining and not closely punctate. Abdomen immaculate, subcylindrical, 

 fullv as broad as and twice the length of the thorax ; basal segment not 

 strongly elevated, longitudinally bicarinate throughout ; second obliquely 

 impressed to its centre ; the intermediate segments not longer than 

 broad ; terebra less than one-sixth longer than the body, with the valvulae 

 pilose and somewhat stout. Legs normal and entirely red ; apical joint 

 of the hind tarsi thrice longer than the penultimate, and all the claws 

 lobate basally. Wings silaceous ; stigma clear red ; radix and tegulae 

 ochraceous or rarely ferrugineous ; areolet nearly sessile and subirregularly 

 triangular ; lower wings with the basal abscissa of the radius half as long 

 again as the second recurrent nervure ; nervellus slightly postfurcal and 

 intercepted distinctly above the centre. 9 Length, 12-17 mm. 



Thomson {I.e.) compares this species with E.ablireviaius {(). F. viii. 7+0), 

 which differs from A', hilnreula/iis mainly in having the epicnemia abbre- 

 viated above ; I must own that the present species appears little more than a 

 variety of E. tubeixulatus to me, differing in its infuscate palpi, less gla- 

 brous metapleurae, more obsoletely bicarinate metanotum, slightly
