Euceros | BRITISH ICHNEUMONS. 281 

near the scrobes, sometimes also behind the eyes, flavous ; frons punctu- 
late and slightly impressed on either side. Antennae of ¢ infuscate with 
the ten basal joints red beneath and six following, excepting black lateral 
dots, flavous; of 9 infuscate throughout, but paler beneath. Thorax 
stout and black with humeral marks, callosities beneath radices, the 
pleural suture and in g@ mesonotal vittae, whitish; areola obsolete, 
petiolar area subsemicircular. Scutellum black with its sides, apex and a 
postscutellar mark, whitish. Abdomen deplanate, black with the in- 
cisures of @ whitish, of Q testaceous. Anterior legs fulvescent with 
coxae and trochanters of @ whitish, of 2 infuscate; hind ones nigres- 
cent with apices of coxae and of trochanters, and the tibial base above, 
whitish. Wings very slightly clouded, with stigma infuscate; radix and 
tegulae white. Length, 5—8 mm. 

This species is instantly known from the next, which it much re- 
sembles, by the lack of a hind tarsal white band and metanotal areola. 
The original male was from Dresden ; subsequently Wesmael found it 
in Belgium, and Holmgren says both sexes occurred rarely in Sweden, in 
the middle of July, 1857; it was bred by Brischke (Schr. Nat. Ges. Danz. 
1878, p. 95) from larvae of Crdaria berberaria in Prussia, and by Giraud 
(Ann. Soc. Fr. 1877, p. 407) from Zhecla quercus. The first British 
specimen is that in his collection, figured by Shuckard (Burm. Transl. 
1836, p. 633) ; Curtis possessed a male, believed to have been taken at 
Birch Wood, though authenticated by Westwood (Mod. Class. ii. 153) to 
have been “reared by the late Mr. Blunt from Achatea piniperda”; Mar- 
shall saw both sexes (E.M.M. 1876, p. 195) taken at Kingussie (/. c. p. 228) 
by Cameron. The Rev. F. D. Morice has given me a male taken by him 
on a rose tree in Chitty’s garden on 7th June, 1902, at Huntingfield, near 
Faversham in Kent; and Mr. G. T. Lyle a bred male of the minimum 
size, raised in the New Forest from larvae of Lupithecia abbreviata on 29th 
July, 1908 ; this specimen had emerged from a lateral hole near one end
