GUNN ON THE ENTOMOLOGY OF NORFOLK. 839 



Norfolk, as many are doubtless aware, is known to be one of the 

 richest counties in the British Isles for its Ornithological productions; so 

 much therefore being noticed in that department, very few observations 

 have lately been made relating to its Entomology. I will here endeavour 

 throughout these few simple notes to convey to the reader's mind what 

 lepidoptera are to be found in this county, although I am well aware it 

 will be impossible to enumerate the whole of the species inhabiting it. 



Norfolk, from the extensive woods, fens, and hedgerows it abounds 

 in, is well adapted for the pursuits of the Entomologist during the summer 

 months, or indeed all the year through, for when the bright and sunny 

 days of summer and autumn are past, the Entomologist's time may be 

 employed in pupa digging during the long and dreary winter months. 

 The village of Horning, situated 14 miles north-east of Norwich, and 

 about the same distance from the sea coast, is a most noted locality for 

 various species of lepidoptera, more particularly PapiJio Machaon, of which 

 however we will speak more hereafter. 1 might also mention several 

 other favourable localities, but think it quite unnecessary to do so, as most 

 of my observations are confined to the outskirts of this city within 

 a few miles radius. These notes are arranged in accordance with Mr. 

 Doubleday's Synonymic list, and I omit all those species which are 

 common everywhere. 



DiURNI. 



Papilio Machaon. This insect, which is the largest and one of the most 

 beautiful of our British Butterflies, although not obtained so abun- 

 dantly in Norfolk as formerly, is still however pretty plentiful, more 

 particularly on the marshes of Horning, where during the summer it 

 is taken in all its stages. I have bred some very fine images myself 

 from larvse taken by a friend in that locality. 



AntJiocharis cardamines. Common, making its appearance in May. 



Gonepteryx rhamni. Not uncommon. 



Colias Helice. Bare. A friend gave me a nice pair about three years 

 since, and assured me he had taken them in this county. 



C. Hyale. Bare. T have a specimen from an old collection, but am not 

 certain whether taken here. 



Vanessa polychloros. Bather uncommon of late years. 



V. lo. Plentiful during 1861 and two following seasons, but more scarce 

 during 1864. 



V. cardui. Bather rare, I have seen a few specimens.
