IN THE BRITISH ISLANDS. 51 



all the above forms from Yorkshire, Isle of Wight, and Sussex locali- 

 ties. On September 9th. 1888, Mr. W. H. B. Fletcher, M.A. of 

 Worthing, wrote to me as follows : " With reference to your remarks 

 on Non. ijeminipuncta ('Entom.' xxi., 225, 226), our Sussex specimens 

 seem to run very dark. I bred one last year with the fore and hind 

 wings almost uniformly smoky, the only marking being a slight pale- 

 ness on the veins in the middle of the fore wings." There is a certain 

 tendency in the darker specimens to become dusted with white scales 

 on the nervures towards the outer margin. A special development in 

 this way would produce the sub-var. paludicola, Hb. 



The following is a classification of the varieties in this species : 

 1. Anterior wings, pale reddish ochreous, reniform forming 2 white 



dots = var. pallida. 

 IA. Anterior wings, pale reddish-ochreous, reniform forming 1 white 



dot = subvar. pallida-unipuncta. 

 IB. Anterior wings, pale reddish-ochreous, reniform without any 



white dot = subvar. pallida-obsoleta. 

 2. Anterior wings, clear reddish-brown, reniform forming 2 white 



dots var. rufa. 

 2A. Anterior wings, clear reddish-brown, reniform forming 1 white 



dot = subvar. rufa-unipuncta. 

 2fi. Anterior wings, clear reddish-brown, reniform without any white 



dot = subvar. rufa-obsoleta. 



2c. For description vide below, subvar. paludicola, Hb. 

 3. Anterior wings, fuscous, with reddish-brown inner margin, 



reniform forming 2 white dots = geminipuncta, Hatch. 

 SA. Anterior wings, fuscous, with reddish-brown inner margin, 



reniform forming 1 white dot = subvar. unipuncta. 

 SB. Anterior wings, fuscous, with reddish-brown inner margin, 



reniform without any white dot = subvar. obsoleta. 

 4. Anterior wings, blackish-fuscous or sooty-black, reniform forming 



2 white dots, = var. fusca. 

 4A. Anterior wings, blackish-fuscous or sooty-black, reniform forming 



1 white dot = subvar. fusca-unipuncta. 

 4fi. Anterior wings, blackish-fuscous or sooty-black, reniform without 



any white dots = subvar. nigricans, Stdgr. 



a. var. pallida, mihi. Anterior wings pale reddish-ochreous, 

 some specimens very pale, with the elbowed line frequently well 

 developed ; the reniform consisting of 2 white spots or one white spot 

 (subvar. pallida-unipuncta), or without a white spot (subvar. pallida- 

 obsoleta). The hind wings pale compared with those of the darker 

 varieties. My specimens of this pale form came principally from 

 Brighton and East Yorkshire. In the Isle of Wight this form is rare. 

 fi. var. rufa, mihi. Anterior wings of bright reddish-brown, 

 sometimes with traces of the dashes forming the angulated line ; the 

 reniform consisting of 2 white spots (rufa), or one white spot (sub- 

 var. rufa-unipuncta), or without (subvar. rufa-obsoleta). I have the 

 variety from Brighton, East Yorkshire and the Isle of Wight. 



y. var. paludicola, Hb. Hiibner figures (624) a fine variety, under 

 this name. It is of a dark reddish-brown colour, with white median 

 and basal nervures, a small black orbicular, the inner edge of the
