were mostly described species, but there were oue new species of Euraenes and 

 three of Odynerus; also Rhynchium ornatum, found also in China; four 

 species of Polistes, two apparently new, P. hebrseus, found also in China, India, 

 Mauritius and Palestine, and the common European P. biglumis, of which 

 scores of specimens had been sent ; lastly, of the genus Vespa, there were four 

 species, V. ducalis, V. japouica, V. mandarinea and V. anchorata. On the 

 whole, the collection was decidedly European in appearance, and though many 

 of the species were widely dispersed, very few of them had been previously 

 recorded from Japan. 



Mr. M'Lachlau exhibited some exotic dragon-tlies ; Hypopetalia pestilens, 

 described in the paper- mentioned below, and Chalcoptery.x rutilans, of which 

 genus a new species is described in the same paper. 



Mr. Albert Miiller exhibited the original drawings of Labram, illustrating 

 the late Dr. Imhoffs Insecten der Schweiz, and other entomological works. 



Mr. H. W. Bates exhibited some exotic Copridie, described in the paper 

 mentioned below. 



Mr. G. R. Crotch sent for exhibition Trachyphloeus laticollis [Schonherr, vii. 

 118), a beetle new to the British list ; five specimens had been captured some 

 years ago at Weston-super-I\Iare. He considered the T. anoplus of Foi-ster, 

 and the T. rectus and spinimanus of Thomson, to be synonymous with 

 T. laticollis, which ought to be placed with T. alternans, spinimanus and 

 scabriusculus, being nearest the former by the weak armature of the tibiae ; the 

 comparatively dense setae separate it from T. alternans and also from T. spini- 

 manus. 



RefeiTin" to the exhibition of Bombycidae described as Oeona punctata, 

 Lasiocampa remota and Lebeda hebes (see Proc. Eut. Soc. 1809, p. xxii.), 

 Mr. Dunning said that he had written to Mr. Holdsworth, calling his attention 

 to the improbability of the same species of larva feeding both on oak and pine, 

 and had received the following, dated Shanghai, 7th February, 1870 : — 



" That the specimens were all bred from the same larvse is correct, and the 

 statement that three distinct species have been made out of them has puzzled 

 me very much. It clearly shows how careful we ought to be, when collecting 

 in foreign climates, to pay greater care to the watching and collecting of larvae. 

 With ref^ard to these Bombyces, it is my opinion that they are male and female 

 of one and the same species. The specimens sent you show, it is true, con- 

 siderable difference in colour and markings, but if you could see the large 

 number which I have in my cabinets, with the varieties gradually merging into 

 each other, I think you would at once proclaim them one species. Again, 

 amongst the hundreds of larvae which I found and bred, the only difference to 

 be observed was in the lighter or darker shade of the ground colour, from 

 blackish brown to velvetty black; and this very trivial difference could 

 scarcely be sufficiently important to constitute distinct species. The hill on 

 which I found the krvje was covered ou one side with small pines, dwarf oak,
