''I show also a series oi pales (is this a true Brenthis ?), var. 

 lapponica. It appears to me to differ Httle from the type ; 

 the ground colour is rather paler, perhaps. This insect has 

 had a great range of variation in every locality where I have 

 seen it in quantity." 



Mr. Lucas exhibited a series of Libelhda qiiadrimaadata, 

 consisting of iive typical specimens, three from the south of 

 England and two from Rannoch, with five suffused varieties 

 extending from the typical form to the var. prcsnuhila of 

 Newman. Some of the last, besides possessing the brown 

 patches, were suffused with saffron near the costal margin 

 of all the wings. The finest prcBniibila was from Rev. J. E. 

 Tarbat's collection. A series of Calopteryx virgo containing 

 three smoky males from Surrey, out of Mr. Tarbat's collec- 

 tion ; a typical male from the New Forest ; a male with the 

 hind wings minus the male coloration, from Mr. Tarbat's 

 collection; a male from the New Forest with the right fore- 

 wing in the same condition ; and four females, one greenish, 

 one of the typical brown form, one with a dark brown bar 

 across the hind wings, and one with all the wings more or 

 less smoky. 



Mr. Nevinson exhibited the following varieties : — Cleora 

 glabraria, an unusually dark variety ; Fidonia clathrata, an 

 almost unicolorous example; Acidaiia contiguaria, one light 

 specimen and a dark one, both taken at Criccieth in 1898 ; 

 Fidonia atomaria, a male with the coloration of the female ; 

 A cidaliamarginipwic^ata, well banded, leaden, and light forms 

 from Cornwall, Wales, and Folkestone; Carpocapsa poinonella, 

 an aberrant example, bred from a walnut, in which all the 

 central and basal portions of the fore-wings were unicolorous 

 and pale. 



Mr. R. Adkin exhibited local forms of A plecta occidta, from 

 the Scotch localities ; the specimens from Forres were pale 

 in colour, with a deep pink shade in many of them ; whilst 

 those from Rannoch were very dark (almost black), with 

 the pale outlining of the markings in strong relief; but in 

 one specimen the hind wings were pale, and sub-diaphanous. 

 DianthcEcia nana (conspersa), from English, Scotch, and 

 Irish localities. The series showing the largest amount of 

 white were from the Scilly Isles ; those from the south of 

 England and Ireland had slightly less ; while in those from 

 the Scottish mainland the dark coloration was more pro- 

 minent, increasing in amount through the Orkney and 

 Hebridean examples, until in some of those in the Shetland 

 series there were no white markings. Also, for comparison
