374 THE NATURALIST. 



specimens are obtained every season in almost every potato field in 

 tliis neigiibourhood; during the autumn of 1861, the owner of a potato- 

 piece, in the parish of Heigham, I^orwich, dug up as many as forty 

 pupse, which a neighbour of his j)urchasecl with the intention of rearing 

 the following season. He placed them in a large flower-jDot, covering 

 them carefully with mould, standing it in his hot house, quite expecting 

 from the extra Avarmth applied to them to produce the imago at a much 

 earlier period than usual ; great, however, was his disap23ointment when 

 only one made its appearance, that being in a crippled condition. I 

 know of an instance of the perfect insect emerging from the pupa-case 

 when laying in an exposed condition ; a caterpillar having escaped from 

 its cage, and changed to its second stage on a piece of Avood that laid^in 

 the cellar, the moth was caught while fluttering about and making many 

 vain endeavom-s to escape from its unnatm^al locality ; the pupa-case 

 being found in the above-named situation. A person with whom I am 

 acquainted is in the habit of placing caterpillars of this species amongst 

 shreds of cork, rotten wood, &c., by which means he sometimes 

 succeeds in bringing out the moth in perfect condition. The larva of 

 Aclierontia atropos subsists chiefly on j^otato leaves, but has occasion- 

 ally been found on the privet-fence. I saw two examples last season 

 which were taken by a lad while feeding on the latter. 



SpTiiiix convolculi. This moth is not uncommonly met with, but its larva 

 is rarely obtained. I had the pleasure of examining one last season. It 

 was of a uniform bright green, spotted with broAvn on its back, and 

 oblique yellow strijjes on its sides. 



>S^. lujustri. Common. Its beautiful larva may be seen feeding on almost 

 every privet-fence, in August and September. 



Chmrocampa Elpenor. Uncoimnon. I have seen a few larvae. 



Macroglossa stellatarum. Uncommon. One imago in 1863. 



Besia tiimliformis. Occurred rather abundantly in this locality in 1862, 

 since then I have not seen a single example. 



Zeuzera cusctiU. Rare. 



Cvsdus llrjniperda. ^Not uncommon. The larva feeds four years before 

 attaining its full growth ; it proves very destructive to timber, particu- 

 larly the willow and elm, as it subsists on the solid wood. 



Hepiulus hedus. Local. I captured eighteen examples during one evening 

 in July, 1864, at Ketteringham. 



H. lupulmus. Common. Appearing in June.
