the ‘Entomologist’s Monthly Magazine,’ vol. xi, p. 214) to the fact that 
Carabus stenocephalus, Fairm., 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 
Retama, 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 Angera 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 spring 
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 Tipulide 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 Psyllidz), together with a description 
of a genus which might be expected to occur in Britain.—F. G.
