a very dwarf condition, the wings expanding to only 17o mm. ; the upper portion 

 of the third cubital cellule in the anterior wings is very much reduced in size, and 

 the dividing nervule ends very slightly before the nervule above it in one of these 

 wings, and very slightly after in the other, the neuration is also otherwise asym- 

 metrical. — Id. 



Recorded localities of British Ichneumons. — The British records of Ichneu- 

 monidj3 appear to be so extremely few and scanty that the variety and extent of 

 the literature which has given them birth is amazing ; and the poor monographist 

 is expected, not only to wade through and collate everything, but also to as far as 

 possible test its accuracy, or he is at once jumped upon by the critic. What I am 

 anxious to obtain is as complete a knowledge as possible of such Ichneumonid.e 

 (excluding Braconid.£) as have had their localities published ; and I here ask all 

 and sundry who do not grudge a post card to refer me to — or better, lend me a copy 

 of — any notice not included in the following list of works, all of which are known 

 to contain specified localities for instanced species : — Forster's* Nov. Spp. Insecto- 

 rum ; Donovan's Nat. Hist. Brit. Insects ; Kirby and ^pence's Introduction ; Curtis' 

 Brit. Ent. and Farm Insects; Gravenhorst's Ichn. Europ. ; Samouelle's Ent. Cabinet ; 

 Stephens' 111. Brit. Ent.; Encyclop. Brit.,* 1842, vol. ix ; Wesmael's Platyuri 

 Europ. ; Desvignes' Brit. Mus. Ichn. Cat. ; Newman's Moths ; Cameron's* Fauna 

 of Clyde (1876) ; Dale's* Lepid. of Dorset ; Berthoumieu's Ichn. d'Europ. ; and 

 the following periodicals :— Ann. Nat, Hist. (1839) ; Ann.* Scot. Nat. Hist, ; Ent. 

 Mo. Mag. ; Ent. Ann. (1874) ; Entom. ; Ent. Record ; Nat, Journal ; The Natu- 

 ralist (1854) ; Young Naturalist ; Trans. Ent. Soc. ; Proc* Berwick. Nat. Field 

 Club; Zoologist.* The only local lists I have heard of are :— Paget's Nat. Hist. 

 Gt. Yarmouth ; Walker's Isle of Man list (Entom., 1872-73, p. 432) ; Roebuck and 

 Bairstow's list for Yorkshire (Trans. Yorks. Nat. Union, 1877-80); Nat. Hist. 

 Hastings with three Suppl (1878-98) ; Marquand's list of the Land's End district 

 (Trans. Penzance Nat. Hist. Soc, 1884) ; Bridgman's Norfolk list (Trans. Norf. 

 Nat, Soc, 1894) ; Parfitt's* Devon list (Trans. Devon Assoc, 1881, p. 241 et seqq.) ; 

 Bignell's South Devon list (lib. cit., 1898) ; and Luff's Alderney List (Trans. 

 Guernsey Soc. Nat, Sc, 1899). Those bearing an asterisk I have not yet examined.

Field Notes on Stridulation. — In this Magazine, 1901, p. 166, I drew attention 

 to the fact that Geotrupes typhosus stridulates, at least in part, by the friction of 

 the abdomen upon the elytra; this fact I still maintain, having tested it upon the 

 living insect, although it is strange that the species should also possess stridulating 

 files upon the coxae, as shown by Mr. Gahan, and confirmed (v. v.) by the Rev. 

 H. S. Gorham. 



It may be interesting to here note a few further observations, made entirely in 

 the field, upon the same subject, which appears to have been studied mainly 

 anatomically upon dried specimens. They have probably been noted before, but 

 Cox lias paid no, and Fowler little, attention to the subject. 



Necrophorus mortuorum and Geotrupes sylvaticus stridulate by rubbing the 

 apical abdominal segments upon the elytra ; the coxae play no part, since, when 

 the elytra are both held open, the insect is incapable of emitting sound : when one
