252 BRITISH ICHNEUMONS. 



Woods, near Ipswich. It is common on the Continent, where it has been 

 bred from Oenectra pilkriana and Depressaria nervosa. 



11. heterogonus, Holmgr. 



Phaeogenes heterogonus, Holmgr. Ichn. Suec. iii. 431 ; Berth. Ann. Soc. Fr, 1S96, 

 p. 372, 6 ? . 



Head black ; clypeus usually indistinctly discreted ; palpi piceous. 

 Antennae black ; of ? with the four basal flagellar joints red, the seventh 

 quadrate and, together with the four following, white ; of $ with flagellum 

 apically ferrugineous beneath. Thorax black ; areola slightly longer than 

 broad. Abdomen black, with segments two to four, apex of first and a 

 mark on the fifth, red ; post-petiole finely and distinctly aciculate ; basal 

 impression of second segment gastrocaeliform, centrally wanting ; terebra 

 incrassate, shortly exserted. Legs normal, black, with anterior femora and 

 tibiae red ; 5 with hind tibiae centrally and femora basally red ; $ coxae 

 with stout, triangular, sub-acuminate teeth. Wings slightly clouded ; 

 stigma fuscous, radix whitish, tegulae black. Length, 7-9 mm. 



The conformation of the head and thorax is very similar to that of 

 P. se/nivulpinus, from which the sculpture of the post-petiole will at once 

 distinguish it ; the form of the clypeus is most nearly like that of F. plani- 

 frons, but the cheeks are distinctly dilated and auriculate apically, which 

 feature will also separate it from P. mela?iogonus. 



I know of but one indigenous example of this species, which was taken 

 at Castle Island, Loch Leven, early in June, 1898, by Mr. W. Evans, who 

 sent it to me for determination ; on the Continent it occurs in Sweden 

 and, it is said, in northern Spain.

Head punctate, obviously narrowed behind the eyes, black ; mouth 

 partly pale ; cheeks as long as base of mandibles, strongly punctate, their 

 external margin sinuate a little before the apex, which is auriculately pro- 

 duced below the mandibles ; clypeus sub-convex, punctate, distinctly 

 discreted and apically broadly rounded. Antennae slightly attenuate 

 apically; of $ trjcoloured, with the eighth flagellar joint quadrate. Thorax 

 entirely black ; notauli indicated ; mesopectoral sulcus and the juxta-coxal 

 areae entire ; metanotal areae complete \ areola hardly longer than broad. 

 Abdomen finely but distinctly punctate, black ; segments two to four and 

 more or less of the first and fifth, red ; post-petiole alutaceo-punctate ; 

 third segment transverse ; terebra slightly exserted. Legs normal, black ; 

 anterior femora more or less and the tibiae rufescent ; hind tibiae often 

 centrally piceous ; $ with hind femora, except apices, and their tibiae, 

 centrally, red ; hind coxae of $ strongly punctate, apically transversely 

 sub-strigose, of $ rugulose, apically depressed, with the carinae obliquely 

 curved in the centre and thence emitting a small toolh. Stigma piceous ; 

 radix pale, tegulae nigrescent. Length, 7-9 mm.
