Insects. 4185 



Orgyia Coryli. Larvae and pupae very common in Beech Wood. 

 The larva is polyphagous, feeding on beech, maple, hazel, oak, &c. ; 

 the pupa is found under moss on those trees. 



Tricbiura Crataegi. One larva on hawthorn. 



Poecilocampa Populi. Pupae at the roots of poplar, ash, and elm, 

 scarce. 



Platypteryx unguicula. This insect was extremely common last 

 year in May, flying in Beech Wood, by day. The female is much 

 rarer, and does not fly by day. It is double-brooded, as I bred it this 

 year in August, from larvae found on beech in July. 



Cerura furcula and bifida. Larvae on poplar and sallows ; pupae 

 on trunks of poplars. 



Stauropus Fagi. Five ; two males : one female pupa under moss 

 on beech, in Beech Wood, and two larvae now in pupa. 



Asteroscopus Cassinea. One larva on sallow. 



Pterostoma palpina. Pupae at roots of poplar ; larvae not very un- 

 common on poplar. 



Notodonta Camelina. Larvae and pupae in great profusion, the for- 

 mer upon beech, oak, hazel, &c, the latter under moss on beech, in 

 Beech Wood. I mention this species as affording a curious illustra- 

 tion of the uncertainty of appearance, in point of time, of some insects. 

 1 had about seventy pupae this year ; the first insect appeared on the 

 9th of May, the last not until the 4th of August. 



Notodonta cucullina. About forty-five larvae on maples, in Beech 

 Wood. I took mine by beating, in August and September, and found 

 maple-shrubs the most productive, especially such as were situated in 

 the denser parts of the wood, a circumstance not usual, as far as my 

 experience goes. Like others of this genus, it seems very subject to 

 the attacks of an Ichneumon. It varies much in appearance, but, in 

 healthy specimens, is generally of a dull green, with a dark patch on 

 the anterior segments, and greatly resembles N. Dromedarius. 



Notodonta dictaeoides. Larvae and pupae not uncommon on poplar. 

 „ Dictaea. Larvae and pupae on poplar, much scarcer than 



dictaeoides. 



„ Dromedarius. Rare ; twelve larvae on hazels, but nearly 



all stung by Ichneumons. 



„ ziczac. Larvae very common on sallow and willow. 



„ trepida. Five larvae on oaks, four being stung. 



„ Chaonia. Three larvae on oaks, all stung. 



Ptilophora plumigera. One larva on maple, May \ produced the 

 perfect insect October 27.
