both may have combined, since even in the most social species some 

 disruptive tendencies exist and at times become powerful, making it 

 probable enough that in the vast lapse of geological time many species 

 might acquire one kind of sociality, subsequently losing it, and again 

 acquiring the former or another type of sociality. Despite the fact that 

 sociality has two kinds of origin, one principal cause has been of 

 immense importance in sustaining and increasing both forms of it, viz., 

 the pressure of external danger ; this truth has already been several 

 times referred to, and further illustration of it is needless. 



Our necessarily brief sketch of the development of the social 

 instincts is now ended. Whilst recognizing that the roots of the tree 

 of sociality lie deep in the soil of sub-conscious animalism, we have not 

 restricted ourselves to an examination of those lower structures, but 

 have looked upwards and seen that it bears also the flowers of ethical 

 sentiment, which, under the ripening influence of religion, yield the 

 fruit of a pure and noble morality. 



REPORTS OF SOCIETIES. 



CITY OF LONDON ENTOMOLOGICAL AND NATURAL HISTORY 



SOCIETY. 



Tuesday, October 16th, 1894. 



Mr. Battley exhibited a drawer containing most of his Agro'-idce ; also colour photo- 

 prints of Vanessa atalanta, V. is, and Chelonia caia, the likeness to the originals being 

 extremely good. The plate was a supplement to a recent number of the magazine 

 called " The Photogram." 



Dr. Buckell, a female Satyrus semale, and a female TZjpinepheh ianira captured at 

 Folkestone Warren on September 2nd. Both were in perfect condition, and he raised 

 the question as to whether the ianira was part of a second brood, or whether that 

 species continued to emerge over a period of two months. 



Mr. Prout, Caradrina ambigua, Noctua c-nigrum, and Aporophyla aiistralis (with dark 

 vars.), all from Sandown ; also Triphmna svbseqita, from Sandown and New Forest. 



Mr. Bate, a specimen of Arctia fuliginosa, bred from a female taken on the last 

 Sunday in June ; the rest of the brood being still feeding. 



Mr. Boden, a series of Solcnobia inoonspicuella. 



Dr. Dudgeon, a female slow-worm (Anr/uis fragilis), and young one. The mother 

 was captured at Heme Bay, and the young one was one of a brood of five ; it was 

 about five weeks old. 



Mr. Clark, Cossus ligniperda, from Tottenham, and Zeuzera pyrina, London Fields. 



Mr. Southey, Xylophasia scolopacina and preserved larvae of the same ; also 

 ichneumons bred from some of them. All were from Highgate Woods. 



Mr. Smith, Zyycena trifolii, from Broxbourne ; Nyssia hispidaria, from Epping 

 Forest ; and Asphalia ridens and Scodiona belyiaria, from the New Forest. 



Mr. Bacot. a series of Bombyx tri/olii, sembled near Liverpool. He said that the 

 species seemed somewhat nondescript, and not very closely allied to any of its con- 

 geners, most of which he exhibited with their preserved larvae.
