Mr. Tugwell exhibited Melanippe hastata, L., from Sussex 

 and the Shetlands, and remarked on their wide divergence 

 and the desirability of obtaining forms of a species from 

 different parts of the country, in order to show the local 

 variation. 



Mr. Nussey exhibited a fine series of bred specimens of 

 Theclapruni, L., and called attention to a large female speci- 

 men that had emerged from the pupa without antennae. 



Mr. W. H. McLachlan exhibited lepidoptera taken by him 

 at Aberdeen, including forms of Polia chi, L., dark forms of 

 Noctua xanthographa, Fb.,. Agrotis liicemea, L., and Epunda 

 nigra, Haw. 



Mr. Billups exhibited Tragus novcs-caledoni^, Montrouzier, 

 a species of Dytiscus, the curious longicorn Enicodes fichtelii, 

 Schr., and a very beautiful species of Cicindelidae, Caledonica 

 lanigera, Chau., and stated that the three species of Coleoptera 

 seemed to be exclusively confined to New Caledonia. Mr. 

 Billups also exhibited two species of Hemiptera from the 

 same locality, Tectocorix banksii, Don., and Mictis symbolica, 

 Don., and remarked that unlike the Coleoptera, these two 

 species had a very wide geographical distribution, the former 

 having been taken in Java, Australia, Timor, the Celebes, 

 and Tonga ; while the latter, in addition to the above- 

 mentioned places, had also been met with in the New 

 Hebrides and Ceram. 



Mr. T. D. A. Cockerell exhibited Arion ambiguus, Pollonera, 

 a slug new to Britain, of two forms : namely var. armoricana, 

 Pollonera, from Sturminster Marshall, Dorset (found by 

 T.DA.C), and a new form, subalbida, having the sides below 

 the bands creamy white, from Bailey Gate, Dorset (found 

 by Mr. W. Wallace). Arion celticns, Pollonera, from Rivar- 

 ossa, Piedmont, Italy ; received from Mr. C. Pollonera. 

 Malacolimax valentianus, Ferussac, from Barcelona ; received 

 from Mr. C. Pollonera ; and read the following note on Arion 

 ambiguus, Pollonera : — 



" This species, of which specimens are now exhibited from 

 Dorsetshire, has not yet been recognised as British. Very 

 probably, however, the Ario?z circumscriptus of Johnston is 

 identical with ambiguus, in which case Johnston's name has 

 priority. But I am disposed to regard A. circumscriptus and 

 A. bourguignati as at most only subspecifically distinct, so 

 that if we use this name (or perhaps preferably Nilsson's 

 name, fasciatus) to include all the British forms of the 

 bourguignati group, we may then reserve the name A. ambiguus 

 for the keelless subspecies ; calling those with a keel, which
