238 BRITISH ICHNEUMONS. [En'oori^i/s 



clypeus pale flavous, with vertical dots and outer orbits partly rufcscent : 

 9 with both inner and outer orbits partly red. Antennae black, with ^ 

 scape flavous-marked beneath. Thorax black and elongatcly pubescent. 

 Abdomen red with basal segment nearly entirely, second discally and the 

 anus, black. Legs black with front ones of $ mainly red, and of J 

 flavidous with tarsi stramineous-white ; hind tarsi with second to fourth 

 joints white, 9 with apical half of the first concolorous and ^ with the 

 second sometimes black. Wings somewhat strongly infumate, with stigma 

 fufescent and tegulae black or piceous; nervures infuscate. Length, 15- 

 20 mm. 



Rarely the anterior tarsi of J alone are white-banded, with hind legs 

 entirely black. 



Sparsely distributed through northern and central Europe, Belgium, 

 France, Germany, Sweden, etc. Giraud claims (Ann. Soc. Fr. 1877, 

 p. 4.05) to have raised it from Diloba caeridcoccphala and Bombyx casinnsis. 

 Our first record is by Curtis (B.E. fol. 736) "Isle of Portland 14th May, 

 and beginning of August Heron Court." Weston found this species a 

 frequent parasite of Zygaena filipcndiilac, invariably emerging the first 

 year (Entom. 1880, pp. 17 et 68); and also attacking Z. lonicerae (I.e. 1881, 

 p. 139). It is by no means common, however; no one appears to have 

 captured it and I have no material ; a male, thought to belong here by 

 Capron, is referable to E. perspicillaior, Grav.

Head black, with the face and mouth and cheeks flavous. Antennae 

 17 mm. in length, rufescent-fulvous with the two basal joints discally 

 black. Thorax black and white-pubescent, with a flavidous and some- 

 what elevated line "on the sides of the metathorax, above the base of 

 the wings"; all sutures and frenum dull white. Abdomen rufescent with 

 only the second segment, except at its apex, discally black. Anterior 

 legs flavous; hind ones rufescent with apical third of their tibiae infus- 

 cate or black ; tarsi fulvous or flavous. Wings flavescent hyaline ; stigma 

 elongate and very narrow; tegulae infuscate-flavidous ; "first and second 

 recurrent nervures forming but one continued line" := "nervo secundo 

 recurrente cum nervo, cellulas cubitales sejungente coincidente." Length, 

 30 mm. (J only. 



The position of the second recurrent nervure certainly places Des- 

 vignes' male described above in Erigorgus, but nothing palaearctic much 

 longer than two-thirds of its size is known, except Habronyx Hcros, with 

 which I was enabled to synonymise it by an examination of the type still 

 preserved in Mr. Dcsvignes' collection, which is the only known British 

 example; and we cannot yet lay good claim to inclusion in our indigen- 

 ous list of this .species, which is everywhere rare in Germany, Sweden, 

 Belgium, France, etc., from August to October. It is said to have been 

 raised in Prussia from pupae of Dcihphila Gahi\ Lasiocampa pini and L. 

 Dryophaga (Brischke, Schr. Nat. Ges. Danz. 1882, p. 135).
