Perhaps a short list of a few of the pupae obtained at 

 these trees may prove interesting/' 



" Elm. — Smerinthus Tilice (why this insect should 

 be called the lime hawk-moth I know not ; I have 

 found dozens of pupae at the roots of elm, but not one 

 at lime), Petasia cassinea, Tceniocampa rubricosa, T. 

 Populeti, T. munda, Cosmia drffinis, Xylina semi- 

 brunnea, Anisopteryx cescularia, $ and $, Hiber- 

 nia leucophearia, $ and $ , S. aurantiaria, $ and $ , 

 &c. 



" Oak. — Considering the number of larvae that feed 

 upon oak, I have been surprised at finding so few 

 pupa? at it. This, I suppose, is partly owing to the 

 fact that a considerable number of the insects whose 

 larvae feed upon oak do not pass the winter in the pupa 

 state. However, when you do succeed in getting one 

 it is generally good, and I have found Notodonta tre- 

 pida, N. Chaonia, N. Dodoncea, Geometra Papili- 

 onaria, Biston Prodromaria, &c. I was much sur- 

 prised to find, on two occasions, the empty cocoon of 

 Cerura Vinula on the trunk of an oak. 



" Ash. — Pcecilocampa Populi, Acronycta Ligustri, 

 Geometra lunaria, G. illustraria, &c, &c. 



" Beech. — This and the poplar are the best trees. 

 At the former I have found Lithosia rubricollis, L. 

 aureola, Orgyia Coryli, Notodonta Camelina, Te- 

 phrosia conso?iaria, &c. ; at the latter Phragmatobia 

 mendica, Pcecilocampa Populi, Cerura bifida, C. 

 furcula, Ptilodontis palpina, Notodonta dictcea, N. 

 Dictceoides, Clostera curtula, Ceropacha Or, C. 

 ocularis, Ypsipetes ruber aria, &c.
