5386 Insects. 



they will generally be found at distances varying from one to three 

 feet from the ground. You will almost invariably find vinula close to 

 the ground. 



Stauropus Fagi. Once found between two decayed beech-leaves. 

 Halton, Bucks. October. 



Petasia cassinea. One female at roots of elm. July. Gloucester- 

 shire. 



Ptilodontis palpina. Occasionally at poplars, but much more 

 frequently at willows, especially when on the banks of ditches, 

 streams, &c. When in such situations, that side of the trunk which 

 faces the stream is often clothed with grassy sods of loose, dry, friable 

 earth: this is the place for palpina; shake the sod well, and the 

 cocoon, which is grayish and of weak consistency, will generally be 

 found among the dry roots : it is easily distinguishable from that of 

 dictaea, being much smaller, — i.e. the cocoon, — and not so much mixed 

 up with earth. End of September. 



Notodonta camelina. Very common under moss on various trees, 

 beech, elm, &c. A little experience will soon enable the beginner to 

 detect it : the pupa is enclosed in a weak cocoon, and, unlike the other 

 species in this genus, terminates in a single point or spike. October, 

 &c. 



„ cucullina. Once found under moss on a beech tree, 



having doubtless wandered from some neighbouring maple. October. 

 Halton, Bucks. 



„ dictaea. See remarks on palpina. This species forms 



a large cocoon, sometimes nearly the size of trepida. 



„ dictaeoides. I have found the empty pupa-cases of this 



species at the roots of birch ? I put a note of interrogation, as, having 

 never bred it, I am not sure. 



„ dromedarius. The only pupae of this insect I ever found 



were in Ireland : they were all, nine in number, taken at the roots of 

 an alder, and produced the variety commonly known, I believe, by the 

 name of perfusca : they seem to me very different from the English 

 specimens of dromedarius. October. 



„ ziczac. Rarely, at roots of poplar. October, &c. 



„ trepida. This autumn I have succeeded in taking no 



less than seventeen of this fine insect: it appears to prefer a sandy 

 soil, and does not seem so partial to corners as others of this genus. 

 Oak. September, &c. 



„ dodonaea. During the present and preceding autumns 



I have taken upwards of 300 pupae of this species, mixed with Chaonia,
