hind margin ; a series of black dots on the pale nervures beyond the 

 reniform area. Hind margin of the liind wings dark oclireous, with a dark 

 transverse shade and lunule." This is a very distinct form, with the 

 ground colour redder than the type, and the ordinary dark shades of the 

 type of a distinctly bright rust-red colour. I have looked over and captured 

 a large number of this species at Deal, but this form must be considered 

 rare there, as I have taken but few of them. I have seen odd specimens 

 amongst those taken by the Folkestone collectors, and I dare say a larger 

 number would occur there, as the species is very abundant. 



Xylophasia, St., litJioxylea, F. 



So mucli uncertainty prevails with regard to the lithoxylea of 

 the 'Vienna Catalogue,' which gives no description, that the 

 lithoxylea of Fabricius ('Mantissa,' p. 182) is generally accepted 

 as the type of the species. This description is as follows: — 

 " Noctua cristata alis deflexis dentatis, cinereis fusco maculatis ; 

 margine postico fusco." " Corpus cinereum. Thorax dorsali 

 brunnea. Alas anticse dentatse cinerese maculis punctisque 

 obsoletis fuscis. Margo posticus tenuissime fuscus. Subtus 

 cinerete margine tenuiori nitido. Posticge cinerese margine 

 postico fusco, subtus immaculatse." 



Hiibner figures the very red form of suhlustris as lithoxylea. 

 It is a species which varies but little, so far as I know ; some 

 specimens appear to be a little more suffused with dark scales 

 than others, but generally the paler specimens sliow undoubted 

 traces of wear. The specimens whicli I have from Greenwich, 

 Strood, Deal, Sligo, and nortbern British localities, show no ' 

 variation worth mentioning. Haworth, in his * Lepidoptera | 

 Britannica,' p. 1G9, gives a good description of this species; but | 

 he accepts Hlibner's fig. 240 as this species, with the remark " -di , 

 magis ferruginea," although it is undoubtedly suhlusti'is. Guenee * 

 also states in his ' Noctuelles,' vol. v. p. 139, that "some lepi- 

 dopterists have supposed lithoxylea a variety of polyodoii." 

 This will give some idea of the closely -allied character of this 

 group when studied through their varieties.

THE INSECT FAUNA OF ST. KILDA. 

 By C. W. Dale, F.E.S. 



At the September meeting of the Entomological Society, 

 Dr. Sharp recorded a list of nine species of Coleoptera from 

 St. Kilda. To that list I can add seven others. 



The Coleoptera of the Isle now consist of: — Elaphrus 

 lapponiciis, E. cupreas, E. uliginosus, Carabus cateimlatus, 

 C. yranulatus, Nebria brevicollis, N, gylknhalii, Calathus
