^. Note on Clijtus Arielis. — Sir, On the 22d of this pre- 

 sent month, (May 1833), I observed three specimens of C////M* 

 Arietis crawling about in one of the cases of birds in our 

 museum, which appeared to have just emerged from the pupa. 

 I examined the case narrowly, and the oak-branches upon 

 which the birds are placed, but could not perceive any aper- 

 ture from which they had made their escape, although it is 

 evident they have passed through their metamorphosis in some 

 of the stumps. The cases have been put up nearly five years, 

 and the last branches I put in were procured in May 1830; 

 and, to prevent the appearance of any insects, I had them all 

 well dried over a stove, and in a drying-house attached to a 

 stuff-presser's shop. 



Whether Clytvs is always three years in arriving at matu- 

 rity, I am not aware ; if such is the case, then my discovery is 

 of little moment, except the proof of their surviving the high 

 temperature to which they were exposed. 



I am, dear Sir, Yours truly, 

 A. H. Davis, Esq. Henry Denny. 



3. Note on Cynthia Cardui. — Every entomologist is 

 aware of the irregular appearance of the above-named insect ; 

 some seasons scarcely a specimen is to be met with, and at 

 otliers they abound over the greater part of the country ; but 

 on Tuesday, October 8th, their numbers in the neighbour- 

 hood of Tooting by far surpassed any thing of the kind I 

 ever witnessed, particularly in the nursery of Messrs. Rollis- 

 son and Sons : it was highly delightful to behold those lovely 

 insects, sporting from flower to flower, in every part of the 

 garden, — but the Dahlia seemed to be their favourite plant. 

 I cannot but suspect those insects to have migrated from some 

 other part of the country ; for, previous to that day, I had not 

 seen a single specimen in the neighbourhood, and but a very 

 few since : — again, it was evident, they must have been 

 " winging their way " for some time, as most of them were in a 

 faded condition.

4. Editorial Criticisms. — Sir, It is with feelings of regret 

 and mortification, that I perceive, from a late prospectus, that 

 your admirable Magazine has not met with that success it so
