reared in the spring of this year from ova deposited by a wild 

 Aviemore female in 1908, the pupae having thus remained over three 

 winters (" Proc. S. Lond. Ent. Soc," 1910, p. 109). Also a short 

 series of the same species reared from inbred ova of 1909, and 

 which had therefore passed two winters in pupa. He said that in 

 his experience a small proportion only of imagines appeared in the 

 first year after pupation ; the greater number in the second, while 

 a few stragglers generally remained over to the third year. 



Mr. Stanley Blenkarn exhibited a tei-atological example of the 

 Coleopteron Carabns nenwralis, in which the tarsi of the right fore- 

 tibia was divided into three, each terminating in a perfect tarsus 

 and claws ; two specimens of Helophoraa ttibercidatus, a very rare 

 beetle, taken by Mr. J. McLeod, near Coatbridge, Lanarkshire; 

 examples of the beetle, GaleruceUa feri/tissoni, taken at Frankfield, 

 Lanarkshire — a species quite recently new to science ; specimens of 

 the curious Hemipteron, Ledra anrita, beaten from oak at West 

 Wickham. 



Mr. Jiiger exhibited a Nematoid worm which had emerged from 

 the larva of a CnculUa. 



Mr. Sperring exhibited a number of aberrations of Lepidoptera, 

 including a smoky suffused example of Casmotnche potatoria from 

 Benfleet ; a seven-spotted specimen of Anthrocera filipendultF taken 

 on June 25th in N. Kent; a Callimorpha dominnla with very dark 

 hindwings and considerable absence of scales ; it was the last to 

 emerge of a brood ; two specimens of Arctia caja, one of which had 

 asymmetrical markings on the forewings, and in the other the 

 hindwings were yellow. He further showed a number of Abraxas 

 grossnlariata bred from larvfe taken from the same spot from which 

 he obtamed smoky suffused specimens two years ago. Last year 

 the two final examples to emerge were smoky. Among those now 

 exhibited many were considerably darker than the normally 

 marked ones, the black being massed mainly towards the outer 

 margin in the forewings. In addition Mr. Sperring exhibited a 

 Dicrannra vinnla of unusually dark coloration, and several 

 Ccenonympha pamphilus with very brilliantly marked undersides. 



Mr. Sperring in making this exhibit wished to call attention to 

 the fact that most of these aberrations emerged either at the 

 beginning of the period of the brood's emergence or towards the 

 end of the time. In his experience this was usually the case with 

 aberrations. 



AUGUST 10th, 1911. 

 Mr. Jiiger exhibited several specimens of different orders, and
