A conversation then took place regarding the extreme 

 abundance of wasps this summer. 



SEPTEMBER i^th, 1893. 

 J. Jenner Weir, Esq., F.L.S., etc., President, in the Chair. 



Mr. H. A. Auld exhibited living larvse of Phorodesma 

 smaragdaria, Fb. ; also two breeding cages for larvse, the 

 construction of which are fully described by Dr. H. G. 

 Knaggs, in the Entomologist's Monthly Magazine for July 

 last, p. 15Q. 



Mr, South exhibited a series of Spilosoma liibricipeda vars. 

 zatima, Cr., and radiata, St., from Heligoland ; a splendid 

 var. of Argynnis enphrosyne, L., taken, in Lancashire : a very 

 pale var. of Vanessa urticce, L., from Monmouthshire ; two 

 aberrant specimens of Abraxas sylvata, Scop. ; an exceed- 

 ingly small specimen of Abraxas grossidariata, L. ; and an 

 unusually blue specimen of Procris static^.s, L. ; and also a 

 series of ZygcEna trifolii, Esp., containing almost all the 

 known forms, with regard to which he remarked that although 

 most authors say the border of the hind wings is broader in 

 Zygcena trifolii than in Z. lonicerce, Esp., it would be observed 

 that in the series he shov/ed the border was of exactly the 

 same width in some examples of each species, whilst in 

 others it was wi ''er in lonicercB than in trifolii. 



Mr. Fenn and Mr. Tutt both remarked that the bluish form 

 of Procris statices, L., was of occasional occurrence. Mr. 

 Tutt said that the Z. trifolii captured by him in North Kent 

 last year had nearly all of them six spots, where previously 

 the five spotted forms were abundant, and that out of two 

 hundred taken, only five were absolutely typical ; in fact, were 

 almost becoming Z. filipendiiice, L. Mr. Weir remarked that 

 these two species do occasionally cross in a state of nature. 



Mr. Fenn exhibited long series of Spilosoma lubricipeda, 

 var. radiata, St., bred from ova received from Mr. Tngwell, 

 the larvae having been reared on the variegated elder ; also 

 long series of Gnophos obscurata, Hb., captured by himself at 

 Folkestone in August, 1893, showing the banded and other 

 forms, also series of the second brood of Macaria notata, L., 

 reared from the ^%%. Mr. Fenn further exhibited examples of 

 the spring and summer broods of Selenia lunaria, Schifif, 

 and read the following notes thereon : 



" The spring forms are from Eltham, Bexley, and Chatten- 

 den ; also a cross between Essex and Sutherland forms. The 

 summer brood -^tr^ bred in August, 1893 ; the parents being 

 from Bexley, and bred from ova. The larvae were reared on
