281 REMARKS ON THE 



sundry species of Lepidoptera, which I did not like to pass 

 over and leave, aliis post commemoranda. I have, however, 

 little new to offer. I cannot say, Dulci animus novitate te- 

 nebo. All I hope for these few lines, is, 



" Ut non ignava legentum 

 Otia delectant, admoneantque mei." 



There remains also for me to remark on several other classes. 

 These I must for the present postpone ; but as you seem to 

 think that your readers would not object to a small slice of 

 Ornithology, I mean to append a list of such birds as have, to 

 my certain knowledge, occurred in this neighbourhood. Per- 

 haps it may be thought by some that there are other places 

 more fitted for such lists. There may be, and perhaps it 

 would not be hard to find one ; but, 



" Non procul a stabulis audet secedere, si quae 

 Excussa est avidi dentibus agna lupi. 

 Quicumque Argolica de classe Capharea fugit ; 



Semper ab Euboicis vela retorquet aquis. 



Et mea cymba semel vasta percussa procella 



Ilium, quo laesa est, horret adire locum." 



I remain, yours most truly,

Pontia napi. Though this butterfly appears here in profu- 

 sion, I never met with either P. sabellicce, or napaa ; which I 

 cannot but think to be mere varieties of this insect. I have 

 often, whilst collecting, been struck with the tendency to vary 

 exhibited by some species in certain localities, whilst in other 

 places we find no such a tendency. I will mention a very 

 common insect as an example of this : — Harpalus ceneus, in 

 this neighbourhood, scarcely ever varies from its type. At 

 Sudbury and Walton I have found nearly every one of the five 

 species it has been divided into equally common. How can 

 we account for this ? 



Leucophasia sinapis. For five seasons I had never found 

 this interesting insect, and had concluded that it had alto- 

 gether disappeared. But in one of the few rambles I have 

 been able to take this year, I captured one specimen. The 

 same day I obtained, inter alia, Lyda inanita, Doros Conop- 

 sea, and Conopia culiciformis.
