that P. cardui came over here in large numbers at times, but 

 he was of opinion that there was no evidence to show con- 

 clusively that it did not live during the winter as an imago. 

 While he lived at Haslemere P. cardui could always be 

 taken in the late autumn, and again in early spring a few 

 dilapidated specimens put in an appearance. May these 

 not have hidden among dead leaves, in tree-trunks, &c. ? 

 In such retreats it would only by the merest chance ever be 

 discovered. 



SEPTEMBER loth, 1896. 



W. Mansbridge, Esq., F.E.S., in the Chair. 



Mr. A. E. Hall exhibited a gravid female of the large 

 West African ant, Ternies hellicosus, from Cape Coast Castle. 

 He also exhibited a series of captured Callimorpha hera, 

 including one of the terra-cotta coloured variety, all from 

 Newton Abbot. This was considered interesting, as show- 

 ing that the habitat was more extensive than it was at first 

 supposed to be. Mr. Hall said that he had a specimen 

 taken in the same locality some twelve years ago. 



Mr. Lucas exhibited a female specimen of Platetrum 

 depressum having the male blue coloration, and a male 

 specimen of Calopteryx virgo, having the right fore-wing 

 without the usual pigment, and to all appearances a female 

 wing. He also showed a male and female specimen of 

 Thaninotrizon cinerettm, a rare apterous grasshopper, from 

 the bank of the Lymington River in the New Forest. 



Mr. McArthur raised a discussion on high flat setting, 

 and in doing so exhibited steel pins uniform in length, such 

 as would necessitate no change in the depth of our present 

 drawers, and suitable for species down to small Tortrices. 

 He also exhibited numerous specimens which he had set in 

 this way. In order to have all specimens at a uniform 

 height on the pin, the gauging must be from the top. The 

 length of pin under the body would admit of several labels 

 being attached and easily read without removing the insect. 

 The pins did not develop verdigris. It would be necessary 

 to stage the smaller species on pith or boletus. 



Mr. Montgomery exhibited a bred series of Dianthcecia 

 capsincola from Eastbourne. One specimen had the sub- 

 marginal line without the usual zigzags, slightly wider and 

 very distinct. The wavy markings exterior to this line 

 generally seen in most specimens were absent in this 

 example.
