206 A CATALOGUE OF THE LEPIDOPTERA OF 



author, but we must recollect tliat few of the subsequent ob- 

 servers have had the same leisure for continued investigation 

 that fell to his lot, and that the beautiful vale of North Tyne, 

 where his principal labours lay, is as yet a terra incognita^ so far 

 as Entomology is concerned. There is certainly every proba- 

 bility that future researches will enable us to corroborate his 

 record of the species, though the paucity of the English Elm, 

 upon which the larva feeds, in many parts of the two counties, 

 certainly does not add to the chances of success.

 Abundant. The females are the earliest of our Butterflies 

 seen on the wing, issuing from their hybernacula on the first 

 sunny days of spring, and again disappearing should cold wea- 

 ther occur. They survive till the early part of June. The first 

 brood of the year, the produce of their eggs, assumes the perfect 

 state at the end of that month, and a second one in September, 

 of which the females hybernate. Wallis quaintly observes : " It 

 frequently outlives the winter by concealing itself in private 

 recesses, where neither winds nor rains can hurt it." I have 

 noticed these hybernated specimens in great abundance, and, in 

 very early spring, about Dilston, where the crevices of the old 

 ruins and walls no doubt afford them comfortable winter quar- 

 ters, and such warm and sheltered spots tempt them early from 

 their hiding places. The larvae, like those of V. loy are gre- 

 garious on Nettles. It is included in the Norton and Twizell 

 lists, and also in " Ornsby's Durham."
