like the last figure in Newman's British Motks, and the other 

 intermediate between this and the type. Mr. Tugwell 

 remarked that both these species were very variable, but one 

 of the examples of segetiini shown was of a most unusual 

 form, and would at first be taken to be a distinct species. 

 There was, however, no doubt that it was a variety of the 

 species in question, and although he had had a large ex- 

 perience of the species, he had not hitherto seen one so 

 striking. 



Mr. T. R. Billups exhibited the following Arachnidae : 

 Heliophanus flavipes, C. Koch, Ballus depresses, Walck, 

 Pachygnatha De Geeri, Sund., with 40 other species ; the 

 three first-named species were taken by himself in his garden 

 at Peckham. Mr. T. R. Billups also exhibited Silvamts 

 suriiiamensis, L., and gave a short description of the habits 

 and economy of this curious coleopteron. 



Mr. W. Manger exhibited male and female specimens 

 of Odontolabrus cuviera, and Protoceriis colossus (?), from 

 Darjeeling, India. With reference to the last-named insect, 

 Mr. Billups expressed an opinion that it was certainly not 

 the sugar-cane weevil, and he was of opinion that the species 

 might be new to science. 



Mr. Tugwell made some remarks, relative to a communica- 

 tion he had received from Mr. Pierce of Liverpool, as to the 

 determination of species of Zygaenidae by an examination of 

 the genital organs, and exhibited drawings, having especial 

 reference to the specific difference of ZygcEua trifolii, Esp., 

 and Z. nieliloti, Esp. ; these drawings showing a most marked 

 difference in the two insects in question.

 J. T. Carrington, Esq., F.L.S., Vice-President, in the Chair. 



Mr. A. Home was elected a member. 



Mr. Percy Russ exhibited a number of species of Lepidop- 

 tera from Sligo, including among others a distinct black-
