considered closely resembled the species or variety fiom the North of England, named 

 Callunae by Dr. Palmer. 



Mr, Mitford exhibited a beautiful brown variety of Biston prodromarius, and a 

 hybrid produced from Phigalia pilosaria and Nyssia hispidaria, respecting which he 

 furnished the following notes : — 



" On the 5th of March, 1859, I enclosed a female of Nyssia hispidaria, which 

 had recently emerged from the pupa, in a gauze-covered chip-box, and also intro- 

 duced a male of Phigalia pilosaria. They copulated, and on the 7th of that month 

 the female deposited her eggs, which hatched the first week in April, and the larvae 

 assumed the pupa stale about a month afterwards. The following March three per- 

 fect and three crippled males, and one female made their appearance. Tn size the 

 males resemble N. hispidaria, but in colour have the lighter and greener tint and 

 transparency of wing of P. pilosaria ; the legs and antennae of the female also are 

 annulated as in the females of the latter species. I should add that but for an acci- 

 dent, which destroyed the greater part of my pupae, I should probably have bred forty 

 or fifty more." 



Mr. Mitford also exhibited the following species of Psyche, with notes on their 

 economy : — 



" P.fusca. Larva of this species abundant in the neighbourhood of Hampstead ; 

 it feeds early and late in the season, chiefly on bramble ; in the summer months, on 

 various trees and plants, more particularly buckthorn, oak and mountain ash. The 

 larvae are hatched in August, and the moths appear the following June twelvemonths; 

 thus they are two years in arriving at the perfect state. The female pupa-cases are 

 found spun up on leaves in an upright position ; that of the male is generally pen- 

 dant from branches or main stems. 



" P. radiella. The perfect insect frequents moist places on Hampstead Heath, 

 in June. I have never found the larva-cases. 



" P. salicolella. The larva-cases of this species were discovered by Mr. Tompkins 

 on buckthorn, and afterwards by myself on birch, at Hampstead : they are & facsimile 

 of a small P. fusca case. 



"The females of these three species remain within the larva-case. 



" P. intermediella. Found on stems of fir-trees at Black Park, in abundance, in 

 June. 



" P. roboricolella. The larva-cases are fonnd on various trees at Hampstead. 



" P. ? Apparently a very distinct species, allied to P. roboricolella, but the 



wings much more rounded, as in P. radiella." 



Mr. Mitford likewise exhibited a fine specimen of Acrolepia marcidella, taken in 

 his garden at Hampstead. 



Mr. Bond observed that the two or three examples of this species hitherto taken 

 in this country were much wasted. 



Dr. Knaggs announced that the Noctua exhibited and described by him at the 

 Meeting of the Society on the 1st of October last as Nonagria? Bondii, had been pro- 

 nounced by M. Guenee to be a species unknown to him. 



Mr. Waterhouse exhibited three species of Scymnus, viz., S. discoideus, and two 

 others which he thought might probably be included by authors among the varieties 

 of that species, but which have difi'erent habits and present distinguishing peculi- 

 arities. With regard to S. discoideus, he observed that all, or almost all, authors 

 slated that the insect was found on, or in the immediate neighbourhood of, fir trees :
