JOTTINGS ON BRITISH ICHNEUMONID^. 173 



entirely on the single female Cryptid in the National Collection, 

 from tiiat of Desvignes ; I have no previous knowledge of this 

 species, but the example in question agrees admirably with the 

 short description of authors (Ichn. Brit. ii. 170). 



Pezomachus rotundiventris, Fst. — This female has, I believe, 

 not been mentioned in literature since first described from a 

 German specimen in the Wiegm. Archiv. 1850, p. 129 ; it has 

 hitherto been unknown with us, and is certainly not in my own 

 collection. One female was detected by Mr. Ernest A. Elliott 

 among Rev. T. A. Marshall's insects, incorrectly named by the 

 latter P. pumilus. The species is, comparatively, very distinct, 

 and came from Deal. 



Mesostemis transfuga. — This species (finally instated as British 

 at E. M. M. 1907, p. 273) is represented by four females, none 

 of which I had seen when writing my notes (^.c). Two are from 

 Marshall's collection, and were taken at Milford Haven about 

 1870; one is from the collection of Desvignes, who labelled it 

 " Phi/gadeuon nov. sp." ; and the last was named for the Linnean 

 Society by Gravenhorst himself, and may consequently be con- 

 sidered a subtype. With these was mixed a small female 

 Pijncocryptus peregrinator, Linn., labelled " transfuga " by 

 Stephens, showing it to be the type of that species in his 

 collection. In Marshall's own collection I found a single pair, 

 evidently taken at the same time and place as his two females 

 above, and agreeing with them ad amussim, but labelled " albi- 

 notahis " ! Here is the solution of the introduction of M. albi- 

 notatus as British : M. transfuga was mistaken for it by Marshall ; 

 and it must be omitted from our fauna. 



Mesostemis maurus, Marsh. E. M. M. ix. p. 241.— Marshall 

 did not examine the five females in the British Collection (from 

 Dr. Heysham's, and taken, presumably, in the neighbourhood of 

 Carlisle), but simply added a name to Fred. Smith's meagre 

 description. It was the latter, doubtless, who erroneously 

 referred them to Mesostenus, as I pointed out in 1903 (Ichn. 

 Brit. i. 220), though the position I there tentatively assigned 

 the species is also incorrect — since I had not then time to 

 examine the hypopygium, which does not extend to the terebral 

 base. Consequently, this species must be referred to Hoplismenus 

 (which had already been done in MS. in the Collection by Bu- 

 checker), wherein it can be but the unknown female of R. comix, 

 Kriech., among the known species. The latter was bred in Austria 

 by Dorfmeister from Pararge mara {cf Ann. Nat. Hofmus. Wien. 

 1890, p. 481 et Berth. Ann. Soc. Fr. 1894, p. 514, male). 

 Unfortunately we know nothing of the origin of these Heysham 

 specimens ; but I possess a female myself from the collection of 

 Alfred Beaumont, which he took at Courten, in Ireland, on 

 September 1, 1893, and I have seen others or another in 

 Bignell's, from South Devon. It is, of course, not an addition
