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

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



Mr. Weslwood 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 larvce, which would render it difficult to refer them 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, Kirhif : 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 closelv-allied species. 



Mr. Smith also exhibited a piece of tube formed of vulcanized ludia-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 Amboyna by Mr. Wallace, in- 

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

 Diomedes, Cram.; also Papilio Codius, and some fine Pierida;. 



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

 Power : — 



Tachyusa sulcata. Taken at Southend. 



Homalota orhata. Taken at Merton. 



Agaricochara lavicollis. Taken at the Holt, Hampshire. 



Oligota granaria. Taken at the Holt, Hampshire. 



Xantholinus glaher. Taken at Holme Bush. 



Quedius fuscipes. Taken at Addington. 



Stei2us solutzis. Taken at Cowley and Lee. 



Stenm (sp. 20 of Mr. Waterhouse's Catalogue). Taken at Shirley. Mr. 



Waterhouse observed that this insect, in some respects (especially in the dark colouring 

 of the palpi), more perfectly agreed with the description of S. providus, Erichs., than 

 did the species which he had supposed was that insect, and which, from its more cy- 

 lindrical form, he now thought might prove to be Kraatz's S. Rogeri. Before, how- 

 ever, this point could be settled, it would be necessary to ascertain the sexual characters 

 of Dr. Power's insect, of which one specimen only had been found. 



Philonlhus signaticornis. Taken at Eastcot and Merton. 



Philonthus nigrita. Tak«n at Eltham. 



Philonlhus pullus. Taken at Portsea. 



Philonthus lepidus. Taken at Deal. 



Mr. Waterhouse also exhibited the following species from his own collection : — 



Oxypoda aterrirna, nov. sp. 



Anisotoma obesa^ Schmidt, A. ciliaris, Schmidt, A. brunnea, Sturm, A.parvula, Sahl.
