350 LEPIDOPTERA. 



rough, grassy, tnfty spaces on the hill-sides ; but the altitude 

 seems to vary, since Mr. W. M. Christy found it in North 

 Argyleshire at not more than 200 to 300 ft. above the 

 neighbouring sea. In the n('rth-\vcst of Ireland it seems to 

 approach still more closely to the coast. When at rest, on a 

 rock or on the ground, it sits close with widely-spread wings. 

 In luigland. though it does not seem ever to have been 

 recorded, it certainly exists on some of the Tnountains. and I 

 have seen a single specimen which was found sitting upon a 

 stone at the roadside u])on Shap Fell, Westmoreland, by the 

 late Mr. \V. G. Ulatch, who, being on an (xoursion and 

 encumbc'red with a bicycle, could not search for more. In 

 Scotland it is found in Stirlingshire, Lanark, J'erthshirc, 

 Argyleshire, Inverness and Sutherlaudshirc, and probable in 

 all suitable places, as recorded by Dr. Buchanan White, in 

 the districts of the Forth, Tay, Moray, Clyde, Argyle and 

 Sutherland. In Ireland it has been i'ouiul commonly on the 

 hills near Sligo ; in Couuemara, Calway ; in Limerick 

 County, Mayo. Antrim, and Donegal. Abroad it is not 

 scarce among the mountains of South-eastern France, 

 Central and Western Germany, Bohemia, Livonia, Finland, 

 South Lapland, and Fastern Siberia. 



[P. aquata, Huh. — This species has recently been 

 recorded as Hritish ; specimens being said to have been 

 captured nearly twenty years ago, along with P. intalhata, 

 in CUimberland. 'I'lie actual capture of the specimens of 

 ( ithcr species srems insudiciently authenticated ; and taking 

 into consideration that /'. ritalhala is not, so far as is yet 

 kiiDwn, to be taken anywhere within one hundri-d and lifty 

 miles of Cumberland, and that the food-plants of both species 

 are alisent from the Flora of that county, 1 think it desirable 

 ti) wait fill' more definite and reliable data before including 

 P. aijuatn among the inliabilants of the Hritisli isles. It is 

 reported to be found in Holland. Belgium, and Germany, so 

 is not a very improbable species here. J
