be found on a critical examination being made ; but in tbese speci- 

 mens there was no indication of a sixth spot. Neither did he favour 

 a further suggestion that they might be the result of a natural 

 cross between Z. filipendulae and some five-spotted species. From 

 the general appearance of the imagines, and the nature of the 

 cocoons, and the position in which they were constructed, he was 

 more inclined to regard the five-spotted insects as a form of Z. 

 lonicerae. He saw no reason why the two species should not occur 

 in one spot, but he would be glad to have the opinion of the meet- 

 ing after the members had had the opportunity of examining the 

 specimens. In this determination Mr. Grosvenor, who also had 

 reared some of a similar lot, fully concurred, as did other members 

 present. 



Mr. Hy. J. Turner exhibited various species of Zn<jaeniilae from 

 the Italian Peninsula, particularly illustrating the remarkable local 

 variation and aberration of the beautiful if. transalpina. 



Mr. Tonge exhibited series of British Zyt/aenidae, including 

 interesting aberrations of Z. trifolii, and many confluent forms of 

 Z. fHipendnlae. 



Col. Eattray exhibited various confluent forms of Zygaenidae. 



Mr. T. H. L. Grosvenor exhibited most of the forms of the British 

 Zygaenidae, and examples of the well-known continental species of 

 the family to illustrate his paper. 



Mr. E. J. Bunnett made an exhibit to show the similarity of form 

 and structure of cocoons in four orders of insects. 

 Lepidoptera, e.g., Malacosoma. 

 Coleoptera, ,, Hypera rmiticis. 



Neuroptera, ,, Hemerobius, sp. 

 Hymenoptera, ,, Jr/nieioiiou, sp. 

 With their respective imagines. 



Mr. Barnett exhibited a long and varied series of Hibernia lenco- 

 phaearia, including banded, mottled, dark, and variegated forms. 



Mr. Grosvenor read a paper entitled " Notes on the Zygaenidae." 

 (See page 64.) 



In the discussion which ensued few menibers appeared to know 

 what particular form was meant by the name liippocrepidis ; the 

 Zygaenid egg was stated to be colourless when mature and at first 

 was opaque ; and surprise was expressed that the species of this 

 family did not exhibit Mendelian characteristics.
