Coleoptera in the Chesham district. — In the little spare time at my disposal 

 during the past few months I have met vFith a few species of Coleoptera which had 

 not been noticed, or rery infrequently seen previously, in this district. Early in 

 April I had a dny's collecting at Tring. At the reservoir there a considerable 

 quantity of refuse, consisting of dead reeds, &c., had been washed up on the banks 

 by high winds just previous to my visit, and this was found to harbour large numbers 

 of beetles, among them being Acupalpus dorsalis, F., A. consputus, Duft., Brady- 

 cellus placidus, QylL, Ilt/obates nigricolUs, Payk., Calodera riparia, Er., Alianta 

 incana, Er., Ilomalota fallax, Kr., and H. nigella, Er. Two specimens of that 

 distinct little insect Qyrophcena lucidula, Er., were also found ; all the members of 

 this genus having now occurred in this district, except O. pulchella, Heer, and it is 

 not unreasonable to suppose that the latter will ultimately be met with hereabouts. 



The following veere also taken in the same situation : Falagria sulcatula, Grav., 

 Heterothops quadripunctula, Gyll., Stenus incrassatus, Er., S. carbonarius, GylL, 

 Platystethus nitens. Sahib., Troyopklceus pusiUus, Grav., Choleva morio, F., Crypto- 

 phagus distinguendus, Sturm, Bayous limosus, GyW., and Poophagus nastitrtii, Germ. 



Amara lunicollis, Schiodte, and a single example of Homalota deformis, Kr. , 

 were found crawling on the sides of a sandpit near Chesham ; also Ilomalota pag ana, 

 Er., and a fine $ Callicerus rigidicornis, Er. The tubercle on the hind body of 

 the male of this species is, by the way, situated on the 1st segment, and not the 

 7th, as stated in Fowler's Brit. Coleoptera, vol. ii. 



At the roots of Ilelianthemum vulgare several specimens of Ilomalota scapu- 

 laris, Sahib., and Trachyphloeus squamu/atus, 01., were taken in June. 



Whilst at Tring again on August 6th, I took single specimens of Miarus gra- 

 minis, Gyll., and M. plantarum, Dej., both apparently on the flowers of Campanula 

 glomerata. — E. Gko. Elliman, Chesham, Bucks : September \2,th, 1900. 



Supplementary note on the distribution, S(c., of Anchomenus quadripunctatus, 

 De Qeer. — Apropos of my record of the capture of this insect in numbers at 

 Woking {antea, p. 202), M. Fauvel has sent me the following note : — " In my 

 Catalogue Col. Gallo-Rhenane, p. 15, I have cited it from Alsace (taken by Linder, 

 near Jadis) and from the Hautes Pyrenees : Barousse and Aragnouet (taken by 

 Pandelle), in the ravines of beech forests, especially under small pieces of charcoal 

 left on the platforms of the charcoal burners, in August. It is a curious co- 

 incidence with your observation that you took this species in a wood that had 

 recently been injured by fire." Dr. Hamilton, in his "Catalogue of the Coleoptera 

 common to North America, Northern Asia and Europe " (Trans. Am. Ent. Soc, 

 xvi, p. 97), states that A. quadripunctatus is a common North American insect, 

 ranging from Alaska to New Mexico, and (following v. Heyden) also quotes it from 

 E. and W. Siberia. M. Fauvel (Rev. d'Ent., 1889, p. 89), in reviewing Dr. Hamil- 

 ton's " Catalogue," quotes the same localities, and adds Japan to its distribution. I 

 purposely omitted quoting any ultra-European localities myself, as I did not feel 

 quite sure that the insects from all these places belonged to one species. If this is 

 really the case, however, it is quite possible (as M. Fauvel suggests to me) that A. 

 quadripunctatus is really of American origin, its nearest allies apparently belonging 

 to the New World, the general facies of the insect being very suggestive of that of
