irrorated with dusky scales ; veins dusky ; hind wings brown, 

 with the base and costa ashy." There is no doubt that the 

 greater number of our Northern, English and Scotch forms 

 would be included under this varietal name. 



(3. var. pygmina, Haw. — This was treated as the type by 

 all our old British authors, the species being thus dealt with in 

 TIaworth, Stephens, Wood, and Humphrey and Westwood's 



* British Moths.' Haworth's description is " the thorax and 

 anterior wings reddish and unspotted, the veins scarcely marked, 

 the hind wings fuscous, the abdomen white." — ' Lepidoptera 

 Britannica,' p. 176. 



7. var. pallida, St. — Figured by Wood in his ' Index. Ent.,' 

 plate XV., fig. 371, and also in Humphrey and Westwood's 



* British Moths,' plate xlvii., fig. 10. At p. 219 of the latter 

 work it is described as : " f of an inch in the expanse of the fore- 

 wings, which are ochreous, whitish, and without any traces 

 of spots or markings ; the veins alone in the apical part of the 

 wing irrorated with dusky scales, and the hind wings whitish." 



^. var. neiirica, St. (non Hb.) — Hiibner's neurica, fig. 381, is 

 another distinct British species. Stephens' neurica, and Wood's 

 ('Ind. Ent.,' plate xv., p. 372), must not be confounded with 

 Hiibner's (Nonagria) neurica, as it is only a var. of fidva. It is 

 described as " about five-sixths of an inch in the expanse of the 

 fore-wings, which are ochreous or brownish red, with a curved 

 row of minute dusky dots beyond the middle of the wing ; the 

 apical veins slightly brownish, and the hind wings pale whitish 

 ash. Taken but rarely at Lea Bridge and Whittlesea Mere." — 

 (Humphrey and Westwood's 'British Moths,' p. 219.) 



E. YSLV. concolor, Gn.* — " Superior wings oblong, with the hinder 

 margin straigliter at first, then more curved than fulva ; of a 

 bone-white colour in both sexes ; lightly powdered with grey 

 at the ends of the spaces between the nervures, and developed 

 into indistinct dark streaks ; a row of black spots always dis- 

 tinct, though faintly marked, in place of the transverse angu- 

 lated line. Inferior wings of a darkish grey in both sexes, with 

 the ends of the nervures and the fringes clearer." (Guenee's 

 ' Noctuellcs,' vol. v., pp. 103, 104). All authors have treated this 

 as a distinct species, in my opinion altogether on insufficient 



* My reasons for treating this as a variety are discussed fully in the ' Ent. Mo. 

 Mag.,' vol. XXV., pp. 52 — 55.
