Tlio President noticed a paragraph in Newman's Entomologist stating that the 

 collection of Butterflies and Moths formed by the late Mr. Henry Doubleday was 

 now being exhibited at tlu Bethual Grocn Museum ; and he hoped that special care 

 would bo taken of it. 



ifr. Dunning exhibited a pair of Caradrina morpheus taken in copiihX in the 

 Regent's Park, the male being dead; and although still attached to the female, 

 several eggs were laid, and larvae hatched therefrom, in the box in which they were 

 placed. 



Mr. Bates read a letter from Mr. Trovey Blackmore to Mr. McLachlan (who 

 was absent), stating that he was nnicli interested in observing a notice in the Pro- 

 ceedings of this Society respecting the habits of Cychrus cylindricoUis, reported by 

 M. Baudi to feed on snails. He had called attention (in the Ent. M. Mag., li, 214) 

 to the fact that Carabus stenocephalus, Fairm., fed on snails, which, in Morocco, were 

 60 very abundant as to form a marked feature in the landscape by covering the bushes 

 so thick Ij- as to resemble, at a distance, clusters of blossom. He had captured in all 

 eighteen specimens of this scarce Caralus, and of these fifteen were obtained citlicr 

 feeding on snails or climbing up bushes of Retama, which were covered with snails, 

 especially with i7e//x^ZaHa^a. The Ca?*aJM.s having an unusually long head, and 

 the protliorax being narrowed anteriorly, enabled it to thrust its head and prothorax 

 a considerable distance within the shell in search of its food. It belongs to a group 

 comprising several species found in North Africa, which much resembles Ci/cliriis in 

 appearance, and which possessed characters sufficiently marked to entitle them to 

 form, if not a genus distinct from Carabim, at least a sub-genus of Carabus. One 

 of them (possibly a var. of C stenocephalus) occurred in the more northern parts of 

 the Atlantic coast of Morocco, and had been named, by Fairmaire, C. cychroccphaJiis ; 

 and another species (C. Aumonti, Lucas) had been found at Oran, and in the Angcra 

 Mountains, near Ceuta, which had a far narrower prothorax ; but, as he had not met 

 with it himself, he was unacquainted with its habits. He believed that other Carahi 

 might be found whose habits were similar to those of C. stenocephalus. Mr. Bates 

 added that this was a remarkable instance of modification of a form in order to adapt 

 it to a different habit. It could not be a case of affinity, for Carabus and Cychrus 

 were totally distinct genera. The President considered that the form was siuijily 

 adapted to the purpose for which the insects were created. 



The President drew attention to a subject Jiow being much discussed in Germany 

 and the United States of America, with reference to the spring and autumn broods 

 of Li'pidoptera, which proved to be modifications of the same species. He was much 

 interested in the subject, and would be greatly obliged to any Entomologist who 

 would furnish him with observations and notes as to the different broods. 



The President read a paper entitled "A Dipterological Note from Pompeii," 

 containing remarks on the habits of the genus Jiombylius ; also descriptions of some 

 new sjiecies of TipulidcB in the British MiisiMnii, accompanied by drawings shewing 

 them to be furnished with hind legs of unusual length. 



Mr. John Scott contributed a monograpli of the British species belonging to 

 the Ilemiptera-Homop/era (family I'si/l/ida-), together with a description of a !;enu8 

 which might be expected to occur in Britain.
