reported liy M. Uuiuli to feed uu snails. He liad already called attention (in 

 the ' Entomologist's Monthly IMagazinc,' vol. xi., p. '-211) to the fact that 

 Carabus stenocephalus, F(jirm., fed on snails, which in Morocco were so 

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

 the bushes so thickly as to resemble, at a distance, clusters of blossom. He 

 had captured in all eighteen specimens of this scarce Carabus, and of these 

 fifteen were obtained either feeding on snails or climbing up bushes of 

 Retaraa, which were covered with snails, especially Helix planata. The 

 Carabus having an unusually long head, and the prothorax being narrowed 

 anteriorly, enabled it to thrust its head and prothorax a considerable distance 

 within the shell in search of its food. It belonged to a group comprising 

 several species found in North Africa, which much resembled Cychrus in 

 appearance, and which possessed characters sufficiently marked to entitle 

 them to form, if not a genus distinct from Carabus, at least a subgenus 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. cychrocephalus ; and another species (C. Aumonti, Lucas), 

 had been found at Oran and in the Augera 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 Carabi might be 

 found whose habits were similar to those of C. stenocephalus. 



Mr. Bates made some remarks on this as an instance of the modification 

 of a form to adapt the insect to a difference of habit : it could not be con- 

 sidered a case of affinity, Carabus and Cychrus being totally distinct genera. 

 The President, however, considered that the form was simply adapted to 

 the purpose for which the insect was created. 



The President drew attention to a subject now being much discussed in 

 Germany and the United States of America, with reference to the sprinf» 

 and autumn broods of Lepidoptera, 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. 



' Papers read. 



The President read a paper entitled " A Dipterological Note from Pom- 

 peii," containing remarks on the habits of the genus Bombylius. Also 

 descriptions of some new species of Tipulid;e in the British Museum, 

 accompanied by drawings, showing them to be furnished with hind legs of 

 unusual length. 



Mr. John Scott contributed a Monograph of the British species belonging 

 to the Hemiptera-Homoptera (family Psyllidte), together with a description 

 of a genus which might be expected to occur in Britain.
