sample of its Entomological Fauna," in which he graphically described a visit to the 

 grand Langdale Pikes in Westinoi'eland in search of this, the only Alpine species of 

 butterfly occurring in England, which he was successful in capturing along with 

 Crambus furcatellus, and other rare mountain species. The Rev. A. M. Moss read 

 a paper, entitled, " Notes on Cidaria reticulata from Windermere," in which he 

 recounted his experience in taking this rare and beautiful moth from its curious 

 food-plant, Impatiens noli-me-tangere, both in the larval and imago stages. Both 

 papers were well illustrated by numerous specimens. Mr. Moss also exhibited a 

 drawer of Bombyces with life-histories. Mr. T. G. Mason, a long series of Tcenio- 

 campa opima, bred a week previously. Mr. John Watson, Colias Hyale, and 

 varieties poliographus and Simoda, and C. Erate, variety sareptensis and ah. erio- 

 ptera, a.\id C. liomanovi. — F. N. Pierce, Hon. Sec, 1, The Elms, Dingle, Liverpool.

Mr. Lucas exhibited living nymphs of the Dragon-fly, Pyrrhosoma minium, 

 from Oxshott. Mr. Tutt, a pine branch with a nest of a gregarious Europterid moth 

 sent from Cannes by Dr. Chapman. It was presumedly that of Cnethocampa 

 filyocampa. He then gave the results of a recent examination of the ova of Tephrosia 

 crepuscular la (bistortata) and T.biundularia,i\\usiriiiing his remarks with blackboard 

 diagrams from drawings made under the microscope that day. There were three 

 distinct batches of ova ; 1, of T. crepuscular ia, 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 all differentiated. Those 

 of T. biundularia were smaller, somewhat oval in shape, of a yellow colour and 

 more opaque, whilst those of T. crepuscularia 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 

 the other, and more variable inter se than either of the other batches, which were 

 remarkably constant in their characters. He was indebted to Mr. Bacot for the 

 opportunity of examining these batches side by side under the microscope. That 

 gentleman had succeeded in breeding the species at the same time, and had forwarded 

 him the ova on the same day as they were laid. He did not know whether each 

 batch was the product of a single female or not. Mr. Tutt then referred to the 

 alleged occui-rence of T. biundularia in Morayshire, and said that the opinion of 

 several Members was that Mr. Adkin's specimen was only T. crepuscularia. Mr. 

 Home's specimen from the same district was now exhibited, and he (Mr. Tutt) said 

 that it was identical with the Perthshire specimen and of the same type as the 

 Central European forms of 2'. crepuscularia. Mr. Montgomery, larvae of Mania 

 maura, which he had obtained from Mr. Young, of Rotherham. Mr. Adkin, 

 specimens of Arbraxas grossulariata, in one of which the yellow band extended 

 across two-thirds of the hind-wing, and in the other the yellow colour was reduced 

 in intensity to a very pale buff. He also showed an Arclia Caja, with fore-wings 

 much suffused with brown and with the blue-black blotches of the hind-wings much 

 run together. A long discussion then took place on the protection of insects in 

 danger of extermination, and finally the following resolution was adopted : — "That
