42 THE QUERIST. 



seems to be some little doubt with regard to the Lepidopterous larvse 

 feeding upon the alder, I take the present opportunity of stating that I 

 have at different times beaten the following larvae from that tree, and 

 all of them not unfrequently, with the exception of Pcecilocampa populi, 

 Ennomos tiliaria, and Zerene rubiginaria. — Pcecilocampa populi, Platypterix 

 falcula, Notodonta camelina, N. dromedarius, Pygara bucephala, Apatela 

 leporina, Toeniocampa gothica, T. stabilis, T. instabilis, Ennomos tiliaria, 

 Chlorochroma cestivaria, Phigalia pilosaria, Piston betularia, Ypsipetes 

 impluviaria, Zerene rubiginaria, and Cabera pusaria. A few years since 

 I had a pupa of Acronycta alni, the larva of which was found by my 

 brother upon alder** in Radnorshire. I have also known the larvae of 

 Geometra papilionaria to be taken off alder. I have several times dug up 

 the pupae of Toeniocampa gothica, instabilis, and stabilis, and Piston betularia, 

 at the roots of alder. I do not suppose that any one ever accused 

 Phragmatobia menthrasti, and lubricepeda, Segctia xanthographa, Agrotis 

 putris, Chersotis plecta, Hadena persicarice, Phlogophora meticulosa, Abrostola 

 urticce, and triplasia, of feeding upon the leaves of the trees under which 

 their pupae are found, as it is well known that they all feed upon various 

 low-growing plants, and I think that Mr. Morris entirely misunderstood 

 Mr. Greene, if he supposes the latter to think that such is the case. 

 The larvae of these insects, like most others, when full fed, select a spot 

 sheltered from damp and moisture, in which to undergo their transform- 

 ations;! and as the nooks and crannies at the roots of trees are 

 admirably adapted for this purpose, it thence happens that their pupae are 

 often found there. The larva of Hadena persicarice is the only larva of 

 those above named which can be suspected of feeding on trees, though 

 I have never taken it upon anything higher than elder; it is however 

 such an extremely polyphagous animal, that is just possible that it mav 

 sometimes aspire to more lofty food. — H. Hart-ur Crewe, M.A., Stowmarket, 

 Suffolk, December 8th., I806. 



° ° Having some years ago been taught to "chop logic" at Oxford College, 

 I hope I am found to aim at precision in what I say, but it seems that 

 I am not so fortunate in being understood as I could wish. The question 

 I asked was, what species Mr. Greene had himself fed in confinement on 

 the ash? and his reply is a re-enumeration of the species he has beat 



* I am glad that this confirms my statement. — F. 0. Mourns, 

 f Is not this exactly what I had stated; I really cannot see that I am open to the 

 charge of having misunderstood Mr. Greene, who without note or comment enumerated, in 

 reply to my qucure as to what species fed upon the ash, lubricepeda and menthrasti as among 

 those he had found at the root of that tree. If this did not mean to leave it to he inferred 

 that those species fed upon the ash, what did it mean? Is it I or Mr. Crewe that mis- 

 understands Mr. Greene's meaning? I will ask Mr. Greene himself to say; nay, he allows 

 on the previous page, 41, that it is to be inferred. — F. 0. Morris.
