Mr. Stevens exhibited a portion of a collection of Coleoptera and Lepidoptera 

 made by Mr. Trimen in South Africa, about 300 miles east of the Cape of Good 

 Hope; and a fine series sent from Sierra Leone by Mr. Foxcroft. 



Mr. Stevens also exhibited a living specimen of Locusta migratoria, which he had 

 captured near Brighton, in which neighbourhood, he stated, the species was un- 

 usually common ihis autumn. 



Dr. Knaggs observed that he had seen a specimen lately taken at Camden Town. 



Mr. M'Lachlan exhibited a specimen of Hadena peregrina, which he had lately 

 captured at Freshwater, Isle of Wight, being the second recorded British example; 

 also Phibalapteryx gemmaria and Eupcecilia flaviciliana, from the same locality. 



Dr. Allchin exhibited a specimen of Synia musculosa, taken at Brighton, and two 

 fine examples of Nola centonalis, taken in Kent. 



Mr. Janson exhibited a fine new species of Adelops, found by M. Jacquelin Duval 

 in the Pyrenees, and fur which he proposed the specific name of Bonvouloirii. 



Dr. Kuaggs exhibited the following Lepidoptera, with notes of capture: — 



CUistera Anachoreta. He had lately been fortunate enough to capture eleven 

 larvae of this insect in one of the home counties, and succeeded in rearing ten moths ; 

 a friend who subsequently took a pupa presented it to him, and this also i cached the 

 imago state. The only reputed British examples of this species hitherto known are 

 contained iu the British Museum Collection, and were obtained by the late 

 Dr. Leach from the collection of Mr. Spratt: so many years having elapsed without 

 the occurrence of other specimens, its claim to rank as a British insect has been 

 almost universally disputed, and the present capture may therefore be looked upon as 

 a re-discovery, 



Aplecta occulta. A specimen taken in his own field at Camden Town in August 

 last. Few examples of this fine insect have occurred in the southern districts of 

 Britain. He had captured, during the past three year^, upwards of ninety species of 

 Noctuse in this piece of ground. 



Emmelesia tceniata. Taken by B. Piffard, Esq., at Tintero, at the end of June ; 

 the locality is interesting, the insect having previously only occurred in Ireland and 

 in the Lake District. 



Eiipitliecia tenuiata. Also taken by B. Piflfard, Esq., at the same time and place. 



Nonagria concolor. Taken at Folkestone, end of June. Some of the Members 

 present were of opinion that it was not that species, the exaniples being paler and 

 apparently a more slender insect than those found in the feu district. 



Simaethis- vibrana. Taken at Folkestone, end of June. Previous captures of this 

 insect certainly do not exceed six examples. 



Diplodoma marglnipunctella. Bred by Dr. Knaggs from larva;, taken chiefly near 

 Epping, at the beginning of June. Dr. Knaggs observed that the case-bearing larvae 

 of this species were by some entomologists considered to be entirely carnivorous; he 

 had, however, found them to feed freely on bramble and hazel. 



Melanippe Jiuctuata, A singular variety, destitute of the larger costal blotch, the 

 central spot being thereby brought out conspicuously. 



Dr. Knaggs also exhibited the living larvae of Acidalia strigillata, he believed 

 never before seen in this country ; they were reared by him from the egg, and were a 

 few weeks old: he observed that he had supplied them with various plants as food, 

 but all were rejected by them till (by the advice of Mr. Henry Doubleday) he had 

 given them the common knot-grass {Polygonum aviculare), on which they fed freely.
