vai'ies, sometimes only one is present, sometimes neither. I 

 have all the above forms from Yoi-ksliire and Sussex localities. 



a. var. imludicola, Hb. — Hilbner 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 reniform lined with white, so as to form a white lunule, 

 the remainder of the reniform blackish, the outer part of all the 

 nervures white on and towards the hind margin. Hind wings 

 dark grey, base paler, with a distinct lunule. I do not know of 

 British specimens of this variety. 



/3. var. uniinmcta, mi hi. — Like the type but with only the 

 lower half of reniform white. Hubner's fig. 637 depicts this 

 form, but is rather dark in ground colour. This form occurs in 

 Sussex and Yorkshire localities with the type. 



y. var. obsoleta, mihi. — Like the type but with the white twin 

 spots characteristic of the type altogether absent. This form 

 also occurs in the same localities with the type. 



^. var. nigricans, Stdgr. — Staudinger described this variety as 

 " the anterior wings wholly blackish, with the reniform in- 

 distinct." How Staudinger can refer Hubner's fig. 624 to this 

 variety, and how he can reconcile the white nervures of Hubner's 

 figure with his description of var. nigricans surprises me ! 



Nonagria, Och., cannce, Och. 

 Treitschke first described this species under the name cannce 

 in ' Die Schmet. von Europa,' vol. v., p. 225, although Ochsen- 

 heimer, in the above work, vol. iv., p. 82, had named the species 

 cannce before this, with reference to previously published figures.* 

 Treitschke's description is as follows : — " alis anticis flavo-rufes- 

 centibus, serie unica maculaque obsoleta in medio nigris." So 

 far as I have been able to judge from continental specimens, the 

 variation is chiefly sexual, the males being strongly reddish, the 

 females yellowish ochreous, and this is borne out by Hubner's 

 figs. 386, 387. His figure 886 is a male ; ground colour reddish 

 ochreous ; median and costal nervures grej^ ; a transverse curved 

 row of seven dots ; hind wings unicolorous grey. Hubner's fig. 

 387 is probably a female of a pale yellow ochreous colour, with 

 median and costal nervures darker; a transverse row of seven 



* Ochsenheimer wrote the first four vols, of ' Die Sclimet. von Europa,' Treitschke 

 finished the remaining vols, after Ochsenheimer's death.
