another species or sub-species of the genus had now been received from Mozambique, 

 on the Eastern Coast of Africa, and yet it had a great resemblance to the forms from 

 Tropical Western Africa.

Society of British Entomologists. 



November 7, 1854. — Mr. H. Harding, President, in the chair. 



Messrs. Jobson, Thome and Oxley were balloted for and admitted subscribers to 

 the Society. 



The President exhibited a box containing, in great variety, the Peronea cristana, 

 and remarked on the extraordinary abundance in which that insect had occurred 

 during the present year, and contrasted this with its apparent scarcity during several 

 preceding years : he also exhibited some specimens of Eudorea murana, which he bred 

 from lichens found on old walls; the insects were accompanied by the pupa cases: 

 also specimens of Depressaria liturella with its food, a species of wild mint ; and a new 

 insect allied to Cochylis stramineana. 



December 5, 1854. — Mr. Harding, President, in the chair. 



The President exhibited the following Lepidoptera : — 



Peronea Schalleriana, together with its pupa-case and food-plant, the common 

 meadow-sweet (Spircea Ulmaria). 



Cnephasia subjunctana, together with its pupa- case and food-plant, the small 

 spreading rest-harrow (Ononis reclinata) : the larva spins together the leaves of this 

 plant, thus making a domicile in which to undergo its transformations. 



Cnephasia Perterana, with pupa-case and food-plant : the larva draws together the 

 petals of the mouse-ear hawkweed (Hieracium Pilosella), and feeds on the stamens. 



Cnephasia Virgaureana, with pupa-case: the food of this species varies greatly ; the 

 President had bred specimens from the common crowfoot, blackthorn and other plants ; 

 many others of the genus are not particular on what plant they feed. 



Sericoris lacunana, with pupa-case and food-plant, the common millefoil (Achillea 

 millefolium) ; the larva draws together the leaves which protect the young buds, and 

 feeds on the interior or heart of the bud. 



Coleophora Viminetella, with pupa-case and food-plant, the common sallow (Salix 

 capraa) : a good description of this insect would be found in the ' Insecta Britannica' 

 (Tineina, vol. iii. p. 223). 



Coleophora Onosmella, with pupa-case and food-plant, the viper's bugloss (Echium 

 vulgare).
