BRITISH ICHNEUMONS. IQ 



here adopted. What his S was, if it existed, I cannot conjecture ; that of 

 /*. fuscipennis, Wesm., with which Berthoumieu associated both sexes, 

 sometimes has the face black, but its hind tibiae are fulvous. 



It has been bred from Callimorpha dominula, and by Bridgman from 

 Melanippe flitctunta, which seems a wondrous strange host for so large a 

 parasite ; Stephens' type was taken by the Rev. J. Burrell, in Norfolk, and 

 is still extant in the British Museum. In France it occurs rarely in woods, 

 in autumn.

Closely allied to the preceding species, but the $ , generally, though not 

 always, has the terebra basally covered by the hypopygium, which in the $ 

 is broadly rounded. Head slightly buccate and narrowed behind the eyes ; 

 black ; $ with frontal orbits broadly white at vertex ; $ with palpi fuscous, 

 a constant vertical dot, and sometimes more or less of the orbits white ; 

 cheeks of $ with long fine pubescence, of $ with sparse, shorter setae. 

 Antennae setaceous, strongly attenuate, with a six-jointed white band above 

 in ? . 'Jliorax stout, punctate, callosities before and 

 beneath radix, and usually the pronotum, white ; a 

 deep sulcus before the metanotum, which is rugu- 

 Metathoracic sulcus of lose ; areola smoother, semi-elliptic, with the apex 

 p. /usctpeiims. emarginatc, and base often sharply pointed ; costulae 



wanting ; posterior area narrow, sub-equilateral ; coxal areae distinct, denti- 

 paral elongate ; mesosternum with an indistinct tubercle before the trisinuate 

 basal margin. Scutellum white, finely and sparsely punctate, with darker 

 hairs. Abdomen brick-red, the basal segment black and apical ones rarely 

 infuscate ; post-petiole aciculate-punctate, its apical angles obtuse and sides 

 trans-striate beneath ; gastrocaeli large and deep, the intervening space 

 sub-aciculate, narrower than the centre of post-petiole ; hypopygium of $ 

 opposite the fifth dorsal segment, of c? broadly rounded at apex, the fourth 

 ventral segment with no central fold. Legs black, front femora apically or 

 within, intermediate at apex, and all the tibiae and tarsi entirely, fulvous ; 

 claws apically fuscous ; hind coxae without scopulae. Wings lighter or 

 darker infumato-hyaline, the apex infuscate ; tegulae black ; stigma fulvous ; 

 sides of the areolet nearly coalescing in ^ above, wider in ? ; radius some- 

 what curved. Length, 16-20 mm. 



This species has been much confused with f. pisorius, in Britain, and 

 there were a fine pair under that name in Mr. W. W. Esam's collection, 

 which he tells me were bred from larvae of Chaerocanipa porcellus, found 

 early in August, at Beachy Head. He found only two larvae, both very 

 small, about half-an-inch in length, and both were already " stung," pro- 

 ducing the sexes of P. fuscipennis during the following June or July. It is, 

 I expect, a not uncommon insect with us. Mr. Bignell has bred it from 

 the above host, on June i8lh. The Ichneumon pisorius of "Nat. Hist. 

 Hastings," second suppl. p. 9, is a (J of the present species and was bred at 

 Camber, near Rye, from the above host. Mr. A. H. Hamm has taken it 

 near Torquay, on i2tli August. It is recorded from lissex, and Beaumont
