74 BRITISH ICHNEUMONS. {^Campophx 



once distinguish it from C. falcator, without having recourse to the 

 elevated oral costa. 



This species has been too much mixed with (\ falcator to ascertain its 

 distinctive range and hosts, but Thomson states it to be distributed over 

 north and central Europe; France, Belgium in July and August, and at 

 Breda in September; raised from Caradrina piilmonaris by Mocsary, 

 originally from jMiselia oxyacanthae by Boie; and from larvae oi Dasychira 

 pudibunda, Acumycta sp., Hylophila prasina and Phalera bucephala by 

 Brischke (Schr. Nat. Ges. Danz. 1880, p. 139). With us Bignell bred it 

 from Hiviera pennaria on the loth and 19th August (cf. Entom. 1883, p. 65, 

 I.e. 1884, pi. ii., fig. 6, and Brischke), Fitch from Fidonia piniarin {I.e. 

 1883, p. 65, e/ 1884, pl.ii, fig. 24); the cocoon is either hard, smooth, 

 cylindrical, black-veined and brown or cylindrical, woolly and drab- 

 coloured {I.e. 1885, p. 18). With us this species appears confined to 

 woods ; W. Ellis has found it in the New Forest, whence Adams has 

 twice given it me in June from Lyndhurst ; Buckell has taken it at 

 Romsey in Hants, Piffard at Felden in Herts, and Mason has bred it at 

 Pelham \^'^ood near Caister in Lines, from Himera peiniaria. On 29th 

 May, 1902, I took a female flying to a birch twig in the Bentley Woods 

 near Ipswich, which looked exactly like a member of the vespid genus 

 Odynerus on the \\ing. 



7. angustatus, Tlioms. 

 Cavipoplex angiisfatits, Thorns. O.E. xi. 1061 ; Schm. Opusc. Ichn, c7 ? . 



A black species with the head strongly constricted behind the eyes and 

 most of the legs, with centre of abdomen, pale flavous. It is similar to 

 C. oxyaeayithae in its conformation and colour, but the head is very much 

 more strongly narrowed behind the eyes with the vertex much less broad; 

 like it, the hind tibiae are entirely flavous, but its tegulae are sometimes 

 black. Length, 8-10 mm. 



Thomson says it is sparinglv distributed over north and central Europe, 

 and adds that Kriechbaumer reared it (O.Fl. 1089) from S/hatie/ia hippo- 

 easta7ii\ in (jermany, Schm. considers it rare. With us it is certainly 

 commoner than the above species, it has been bred troni Cahera pusatia 

 at Kings Lynn in Norfolk (Bridgman) and taken in Wyre Forest in May, 

 1890 (Martineau); I have numerous examples from Greenings during 

 June, 1871 (W.Saunders), Pyrford in June (Morice), Croydon (Brunetti), 

 bred from a Yorks larva and taken at Grass Wood, Wharfsdale, on 7th 

 Sept. (Porrilt), Guestling in 1888 (Bloomfield), bred from Geometrid 

 larva at Gunton Wood, Lowestoft (Campbell-Taylor), and from its own 

 dull white and felted cocoon inside that of Bupalus piniaria at Withy- 

 combe near Taunton, which Slater sent in November, and excluded the 

 imago the following year.

Head posteriorly constricted ; mandibles and palpi black ; frons not 

 impressed above the scrobes ; cheeks elongate. Antennae with the basal 

 flagellar joints distinctly discreted, and the first half as long again as the
