JOTTINGS ON BRITISH ICHNEUMONID^.. 169 



but the other two specimens belong to distinct species under the 

 genus Ichneumon, s.s. S. defraudator is probably included on 

 the strength of I. sedulns of Desv. Cat., but all its exponents 

 belong to Barichneumon. Of S. apjicus there is no trace, though 

 introduced by Stephens in his illustrations of 1835. There are 

 nice series of both S. culpator and .S. j^istoritis, which must be, 

 or have been, much commoner elsewhere than is now the case 

 in the east and south of England ; a tine male of the latter, 

 taken by Fred. Smith in N. Devon, is suggestive. 



Ichneumon ruficeps, Steuh. = Melanichneumon sangidnator, 

 Eossi. 



Ichneumon pallidatorius, Steph. = Cratichneumon coruscator, 

 Linn., male. 



CoelicJineumon alhicillus, Grav. — There is a male Cratichneu- 

 mon fabricator, F., ex coll. Steph., bearing a printed label 

 ^^ Alhicillus, Grav.", which probably constituted the species 

 brought forward by Stephens, and, as no one has found the 

 Simon Pure since the latter's record, it should be regarded 

 as doubtfully indigenous. 



Ichneumon alhimanus, Steph. vii. 133 = Cratichneumon fabri- 

 cator, F., male. 



This is not the place to go into the distinctions between 

 Cratichneumon nigritarius and C. albilarvatus, which appear 

 little more than colorational ; if they be distinct, my details 

 of capture, &c., in Ichn. Brit, i, must be referred to the latter 

 and not the former. 



Ichneumon Walkeri. — The single male in the collection is 

 labelled " Ich. Walkeri'' in Francis Walker's writing; this is 

 not the type, but the supposititious alternate sex as described by 

 me. The type is a female, of which Wesmael simply says (Bull. 

 Ac. Brux. 1848, p. 184) : " Specimen unicum ab oculatissimo 

 entomologo Do Walker ex Londino accepi." I am glad to learn 

 from Dr. H. Schonteden that the type is still extant in Wesmael's 

 collection in the Musee Koyale d'Histoire Naturelle de Belgique. 



Ichneumon raptorius, Steph. — The author's " type " is a 

 large female /. gracilicornis ; and his I. quadrinotatus is, as I 

 have pointed out, referable to the same species. 



Ichneumon quadrialbatus. — The five males that were doing 

 duty here are all referable to Melanichneumon nudicoxa, Thoms. 

 (= albosignatus, Steph., nee Grav.). 



Ichneumon maculiventris, Desv. — A re-examination of Des- 

 vignes's typical and unique female proves, without possibility of 

 error, that it is synonymous with Hepiopelmus leucostigmus, 

 Grav., var. vielanog aster, and not (as ignorantly stated by me, 

 E. M. M. 1902, p. 122 et Ichn. Brit. i. 170) with Ctenichneumon 

 caruleator, Zett, which must consequently be deleted. 



Ctenichneumon plicatus, Mori. =: Spilichneumoji occisoi'ius ,FsLh., 

 var. nigrinus, Berth. Ann. Soc. Fr. 1895, p. 646. Professor 



ENTOM. — JUNE, 1910.
