bein«^ riddled in all direclions by the larvae, and the debris mingled with the remains 

 of countless members of by^^one generations. 



Stenus solutus, Eric., captured at the same time and place as the specimens pre- 

 viously exhibited by Mr. Edwin Shepherd, to whom I am indebted for the opportunity 

 of taking this scarce and local species. 



Lallirobium punctalum, Zetterstedt, Faun. Ins. Lappon. i. 84, 5 (1828), to whom, 

 and not to Nordmann, this species must be assigned, he having first elaborately 

 described it under this name. 



Mr. Westwood remarked that Cossouus linearis used to be taken in Battersea 

 Fiehls. 



Mr. Janson rejoined that it was certainly not there that he had met with it: little 

 anxiety need, however, be felt as to the precise locality which had yielded it, as he had 

 not only secured but set out an ample supply for all his friends, and specimens (a 

 dozen if he desired them) were quite at Mr. Westwood's service. 



Mr. Gloyne observed that he had taken a specimen of Oodes Helopioides on the 

 banks of the Thames, near Morilake. 



Mr. Staiuton exhibited a new species of Cemiostoma, bred by Mr. Wailes, of 

 Newcaslle-on-Tyne, from larvae mining the leaves of Genista tinctoria, for which the 

 name Wailesella had been proposed : the insect was closely allied to C. spartifoliella • 

 and laburnella, but smaller, and with a bluer tint than those species. 



Mr. Westwood wished to know whether the larvae of these closely-allied species fed 

 on closely-allied plants; if so it was most probable that they were not distinct species, 

 but merely modifications produced by the difference in the food plant. 



Mr. Stainton observed that, independently of the differences in the larvae and 

 perfect insects, differences which truly were minute, there were differences of habit, 

 especially between the larvae, which would render it difhcult to refer tliera to the same 

 species; and to assume that because the differences were small, and because the larva 

 fed on a different plant, the difference of food should so modify the insect in all its 

 stages, seemed rather like begging the question : it was possible the effect of the food 

 might be to alter the appearance of the insect, but that was certainly a point which 

 required to be proved before it could be admitted. 



Mr. Smith exhibited a Stylops which he had bred from a living example of 

 Andrena fuscata, Kirby : it emerged from the pupa at half-past nine o'clock that 

 morning, and although he endeavoured, by keeping it in as cool a place as possible, to 

 preserve it alive to exhibit that evening, it died at about half-past four o'clock : he 

 believed it to be the same species which he had lately figured in the Society's 

 ' Transactions,' or certainly a very closely-allied species. 



Mr. Smith also exhibited a piece of tube formed of vulcanized India-rubber, con- 

 taining cells of the leaf-cutter bees : the cells were placed transversely in the tube, 

 which he considered an extraordinary instance of sagacity in the bees. 



Mr. Stevens exhibited some butterflies, taken in Aniboyna by Mr. Wallace, in- 

 cluding beautiful males of Papilio Ulysses, and the female of this species, the Papilio 

 Diomedes, Cram. ; also Papilio Codrus, and some fine Pieridae. 



Mr. Waterhouse exhibited the following Coleoptera, from the Collection of Dr. 

 Power : — 



Tachyusa sulcata. Taken at Southend. 



Homalota orhala. Taken at Morton. 



Ayaricochara IteviculUs. Taken at the Holt, Hampshire.
