5384 Insects. 



disheartening, and accordingly, in the hope of encouraging despondent 

 " diggers," I now append a list of insects, all of which have been taken 

 by me in this way. Having this object in view, the commonest species 

 are included, with a description of the tree, locality, time of ap- 

 pearance, &c. While this may prove uninteresting to the experienced, 

 it will, I trust, be instructive to the beginner, for whom I write. Where 

 no other locality is mentioned, Suffolk is intended. As there appears 

 to be a biennial change in our nomenclature, I have thought it best to 

 adopt, as most generally known and used, Doubleday's ' Synonymic 

 List.' 



Thecla Rubi. A pupa of this insect was once found under moss 

 on a log of wood. Bucks. 



Satyrus JEgeria. I have several times met with the pupa of this 

 butterfly, suspended from blades of grass, when digging at the roots 

 of trees. It is a beautiful grass-green colour, and passes the winter in 

 that state. 



iEgeria apiformis. Vide ' Intelligencer,' p. 18. This insect, though 

 I have not seen it on the wing, seems to swarm here, judging from the 

 number of pupa-cases in the trunks of poplars. 



Smerinthus Tiliae. Found commonly. Birch and elm. Prefers 

 the narrow angles formed by the roots, getting in as far as possible. 

 October, &c. 



„ Populi. Common. Various poplars : edges rather than 

 the angles. October, &c. 



„ ocellatus. Scarce. Willows. October, &c. 



Euchelia Jacobeae. This insect is, I believe, considered very 

 common, yet I never took more than one specimen in England : far 

 otherwise, however, in Ireland, where it abounds, and I have taken the 

 pupae in boundless profusion under loose bark on wych elms ; of course 

 the larvae must have crawled up the trunks to form theft* cocoons, as 

 they feed on the ragwort. I think it must be local, as that plant is 

 very common here, yet I have not seen the insect. 



Lithosia rubricollis. In abundance under damp moss, decayed 

 bark, &c. Chrysalis short and stout, enclosed in a delicate white 

 web. Should be occasionally damped. Fir, larch, oak, &c. 

 October, &c. 



„ quadra. Occasionally. Spun up on palings, in the 

 neighbourhood of trees covered with lichens. End of June. 



„ griseola.* May be found under moss on lichen-bearing 

 trees. June.
