the variation in the depth of the marginal band of the 

 hind-wings, which in some cases has gone to vanishing 

 point ; also there are three without any markings on the 

 apical patch of the fore-wings. The two forms of the 

 female are represented, viz. the white and the yellow, and 

 one female has very dark hind-wings, approaching C. cdusa 

 var. hel'ice.'" 



Mr. Adkin read the Report of the Field Meeting held at 

 Paul's Cray Common, on September 22nd (see page 17). 



OCTOBER nth, 1900. 



Mr. W.J. Lucas, B.A., F.E.S., President, in the Chair. 



Mr. Robert Adkin exhibited series of the spring and 

 summer broods of Zonosoma porata and Z. ptmctaria, all bred 

 from Sussex ova. He remarked upon the much greater 

 difference between the two broods in the latter than in the 

 former species, and the consequent nearer resemblance 

 of the summer broods of the two species than their 

 spring broods. This resemblance, although superficial, had 

 he said, frequently in his experience led to a confusion 

 of the two species. He thought, however, that apart from 

 the numerous minor characters, the presence of the white 

 dark-bordered dot on the wings of porata should at all times 

 be sufficient to identify that species. He also mentioned with 

 regard to pnnctaria that, although the larva was an inveterate 

 oak feeder, he had found that it would eat beech fairly well, 

 and will not altogether refuse birch when no other food is to 

 be had. 



Mr. Lucas, on behalf of Mr. Jennings, exhibited the 

 Hemiptera, Ptilophoriis perplexns, beaten out of oak at Edmon- 

 ton, and the rare Monanthia ciliata, taken near Dorking, 

 in August ; also a very dark small male of the earwig, 

 Forficnla a^iricnlaria, from Box Hill, which had the legs and 

 wing-cases almost black. 



Mr. B. Adkin exhibited several finely varied specimens of 

 Boarmia rcpandata bred from New Forest larvae, two bred 

 examples of Cleora glabraria, one of which was a nice suffused 

 variety, and various forms of Noctua castanea {ncglecta) from 

 Aberdeen and the New Forest. 



Rev. H. Wood exhibited a fine specimen of the rare Longi- 

 corn, Asiynomiis crdilis, taken at Northampton, and doubtless 

 bred from foreign timber.
