80 THE ENTOMOLOGIST. 



collection of Lepidoptera in a case with a glass lid, which stood in a 

 well-lighted room for some ten years : the diurnal Lepidoptera were 

 but little changed, but the nocturnal ones showed a complete absence 

 of colour ; the marks, which could still be distinguished, were in 

 different shades of grey ; even the blue of C. fraxini and the red of 

 0. mipta had turned to a whitish grey. 



The third specimen to be referred to is a female Polyommatus 

 hippotho'e, ab. This is a cripple ; on each side alternately one of the 

 wings is fully developed, and the other deformed. The upper surface 

 shows on the two fully-developed wings no marked differences from 

 normal Pohjommatus, except that it is rather less red. The undersized 

 wings are of a uniformly dark brown colour, without any marks at all. 

 The under surface is of a greyish colour, the orange being only in the 

 middle of the fully-developed wings. Of these last the fore wing has 

 almost the normal number of spots ; those on the submarginal series 

 are elongated, the first two especially so ; hind wing with fewer spots, 

 first two of submarginal series elongated, and there is much red on the 

 marginal area. The two small wings : fore wing has only one spot 

 in the centre, all the others are obliterated, and only faint indications 

 remain of the submarginal series ; hind wing has only two distinct 

 spots on the submarginal area ; these are very elongated, and there 

 are some further spots on the marginal and submarginal areas to be 

 faintly traced ; the basal spots are distinct. 



In conclusion I wish to add that this summer the varieties were 

 unusually plentiful : thus for instance Helotroplm fibrosa and Anyerona 

 ion/l((ria were much oftener met with than the types H. leucostupna and 

 A. prunaria. All the above-described aberrations were captured near 

 Lauga, Govt, of St. Petersburg. — B. N. Menshootkin ; Chemical

CAPTUEES AND FIELD REPORTS. 



Leucania extranea, Gn., in the County of Cork. — A small 

 example, ouly \h in. in expanse, was taken near Timoleague, on the coast 

 of Cork, at sugar on a railway post, in September last, by Mr. R. J. F. 

 Donovan. He sent it to me for identification, correctly named from New- 

 man, but wished to make sure of its identity, as he is only a beginner. The 

 specimen is in tolerable condition, and there can be no question as to the 

 species. This is the second Irish capture ; the other is in the cabinet of 

 the Hon. R. E. Dillon, and was taken in the same month at Clonbrock, 

 Co. Galway, which is some thirty miles inland from the sea, whereas 

 Timoleague is on the Cork coast. It would therefore appear that the insect 

 is indigenous here, though possibly originally introduced from America by 

 ships. The species has not been taken on the European continent, and in 

 Staudinger's Catalogue " Mad; Angl. m. (advena ;•)" is given, which suggests 

 a doubt as to the identity of Mr. Bond's specimen from Freshwater in 

 September, 1859, an untenable supposition. Mr. R. Donovan's brother. 

 Dr. C. Donovan, collected Lepidoptera assiduously near Glandore, Co. Cork, 

 before he went abroad, and rendered me much valuable help in studying the 

 distribution of Lepidoptera in that district of the county. It is to be hoped
