(6) In the 9 f' the abdomen of discolor is niore thinly scaled than 

 in punctirena, is longer, more narrowly tapering, and the ovipositor more 

 often protrndesf 



(7) Discolor is, at Calgary, slightly the larger species of the two, and 

 during 1903, when both were fairly common, WciS quite three weeks later 

 in appearance, and continued turning up *at treacle after punciirena was 

 over. This last is certainly not amongst my least important points. 



Of European paleacea, Esp., {Euperia fulvago, Hbn.), I have 7 

 ^ ^ and 3 $ $ from the British Isles, chiefly from Sherwood Forest, 

 Notts, and d $ $ and 215? bearing labels of numerous other European 

 and some Asiatic localities. If it were not that I feel so confident of the 

 distinctness o^ discolor and pnnctirena in this one locality, I might easily 

 have been deceived into looking upon both as local races or mere varieties ' 

 oi paleacea, which combines some of the characters of both. But it com- 

 bines them in such a way as to bespeak a third species. It comes between 

 them, but without connecting them. In colour it is brighter than either, 

 but in the 37 specimens before me there is unich less colour variation 

 even than in discolor, and scarcely any tendency to a smoky suffusion. A 

 few specimens of all three can be found to match in colour almost exactly. 

 It varies from a very pale golden-yellow, through straw, to orange. The 

 latter form is, I believe, the var. augulago of Haworth, and the var. A. of 

 Guenee. The former, though mentioned in Tutt's ''British Noctuse and 

 Their Varieties," Vol. Ill, p. 19, is entirely omitted from the Staudinger 

 Catalogue, in which, however, an aberration Teiclii is listed and referred 

 to as a form shaded with fuscous. Cohnir, however, is not usually of 

 important s]-)ecific value in forms in widely separate localities. The t. a. 

 line has generally the sharp angulation o{ discolor, which is conspicuous in 

 a series, though a few specimens have it decidedly blunt. The discoidals 

 have a stronger tendency to be concolorous than even in pnnctirena, and 

 the dark spot in the reniform is strongly developed in all my specimens 

 but one, in wiiich the entire maculation is so faint that the spot, though 

 discernible, has almost become obsolete. The secondaries are frequently 

 immaculate, but have sometimes a slight dusky or even pinkish shading 

 in their lower portion. Tlxe 9 abdomen, though scaled as \n pnnctirena, 

 is long as in discolor, but not quite so sharply tapering. The ovipositor 

 sometimes jirotrudes. So \.\\:vi paleacea, whilst in colour of both ])rimaries 

 and secondaries it cannot be called either intermediate, or nearer to one 

 than to the other, has usually the sharply angalated t. a. line of discolor, ihe 

 discoidal spots ol pnnctirena, and a ? abdon7en somewhat intermediate
