Tinea semifulvella. Richmond Park, June 17. 



Aradus corticalis. Inhabits dried Boleti, in which I found them 

 on stumps of trees and on palings in the New Forest, in June, 1841. 



The saccharine system of taking moths has proved very successful 

 to me, so far as numbers are concerned. There are two posts in our 

 little garden here, which I have wetted with sugar and water every 

 night that I have been at home, and to these the moths came in droves 

 — common sorts in general, it is true, yet occasionally I get a good 

 one. Nonagria Vectis was taken in this way. I think some of our 

 rarer moths might be obtaiTied in this manner, if collectors living near 

 their localities would try it : Mr. Edleston however says that it is use- 

 less at Manchester, possibly the sugar he uses is not strong enough ; 

 treacle I find does equally well. Having informed several friends of 

 the capture of the two larvae noted in a previous number (Entomol. 

 309), they joined in the search for more, and during April a good ma- 

 ny were taken : these have hitherto produced Triphaena orbona, T. 

 janthina, T. fimbria, Graphiphora brunnea, G. triangulum, G. baja, 

 G. festiva, Phlogophora meticulosa, Polia bimaculosa, P. tincta, Ou- 

 rapteryx sambucaria and Campaea margaritata. All these larvae were 

 nearly full fed, and had doubtless lived through the winter. Their 

 capture by lamp-light should be an inducement to search for the larvae 

 of other and rarer species, on plants whereon they are known or sup- 

 posed to feed. — J. W. Douglas; Cohurg Road, Kent Road, July 6, 1842. 



206. Note on the Species and Economy of Cerura. In submitting 

 to you the following views, it is not my intention to put my opinions 

 in opposition to those possessing more scientific knowledge, I shall 

 merely state my practical experience on the subject. I have for se- 

 veral years taken the smaller species of this genus in the larva, pupa, 

 and imago states. Last autumn, from very distant localities, I took 

 several larvae amongst which two were distinct ; subsequently 1 found 

 several in the pupa state ; all these, during the latter part of May and 

 the beginning of June I have bred. As far as I can perceive several 

 species in the Catalogue are produced from the same larvae ; the two 

 which were different from the others are smaller, but I cannot per- 

 ceive much variation in their markings. Mr. J. Standish, this last 

 and the preceding autumn (October), beat off sallow two larvae which 

 appeared to be different, and have produced what is called bicuspis, 

 which I think is a good species ; and from the others I think all the 

 species can be made out, \ioweyex I must think so till I see the larvje. 

 The following account of the economy of the larvae of these insects 

 may interest some of your readers. Before they enter the pupa state,
