year. Mr. Tutt, specimens of Ar/lais (Vanessa) urtica, var. ichnusa, 

 from Corsica, and remarked that Mr. Merrifield's experiments had 

 resulted only in an approximation to this var. He also showed speci- 

 mens of llutis cerisi/i, var. dojrolii, from S.E. Europe. Mr. Adkin, 

 two series of Pachnobia hyperhorea (aJpina), one from Rannoch and the 

 other from Shetland, and made remarks on its local variation and its 

 unaccountable intermittent appearance. In the discussion which 

 followed, Mr. McArthur gave his experience of its appearance in 

 alternate years. Mr. Tutt suggested that the species still retained 

 its boreal habit of remaining two years in a larval condition. Mr. 

 Adkin instanced Uetinia resmella as having a jjrecisely similar habit. 

 Mr. Mansbridge, a smoky var. of Spilosoma luhricipeda from York. 

 Mr. Tunaley, a large number of species from Aviemore, including long 

 and very varied series of Erehia crJhiops, Eupithecia sobrinata, Larentia 

 didytnata, Thera simulata, T. Jinnata, Cidaria immanata, Emmelesia 

 minorata, Pcedisca opJithalmicana, Gelechin popiddla, and others, espe- 

 cially selected to show the range of variation occurring in that locality. 

 Mr. Tunaley read a paper entitled "Notes and Observations in a 

 Holiday in the Black Forest of Scotland from July 29th to Sept. 10th, 

 1896." In a few words he described the geographical surroundings 

 and the geological formation of the district, together with an account 

 of the weather he experienced and some remarks on the necessary 

 equipment for collecting among the Scotch mountains. He then took 

 the more prominent species, and described the variations, peculiar 

 habits of life, and their protective resemblances. Several of the species 

 were noted as having different times of appearance at different elevations, 

 e. g. E. (cthiops. He said that Cloantha solidaf/inis at rest on a fir-post 

 closely resembled a piece 5f curled bark, and pointed out the extensive 

 variation in the central band of T. jxiniperata. The paper was inter- 

 spersed with apt remarks on Scotch characteristics and terse descrip- 

 tions of the environment of each species. In the discussion which 

 followed, Mr. Tutt compared the habits of E. (tthiops in the Alps with 

 those of the species in Scotland, and also contrasted the allied species 

 E. lif/eci, which hid in the fir trees on the disappearance of the sun. 

 Mr. Barrett said that Epinephele ianira also roosted in the branches of 

 trees at sunset. 



March 11th. — The President in the chair. Mr. Lucas exhibited 

 living nymphs of the dragonfly, Pyrrhosouia mmmm, from Oxshott. 

 Mr. Tutt, a pine-branch with a nest of a gregarious europterid moth, 

 sent from Cannes by Dr. Chapman ; it was presumably that of Cnetho- 

 campa pityocampa. He then gave the results of a recent examination 

 of the ova of Tephrosla crcpuscularia (bistortata) and T. bhindidaria, 

 illustrating his remarks with black-board diagrams from drawings made 

 under the microscope that day. There were three distinct batches of 

 ova : (1) of T. crepuscidaria, (2) of T. biundularia, and (3) of the result 

 of a cross between the two species, a female of the former and a male 

 of the latter. The shape and texture of the three batches were well- 

 differentiated ; those of T. biundularia were smaller, somewhat oval in 

 shape, of a yellow colour, and more opaque ; whilst those of T. crepus- 

 cidaria were cylindrical with rounded ends, of a pearly-green slightly 

 transparent and iridescent. The ova which were the result of the 

 cross were intermediate in size, slightly more rounded at one end than
