9$ VARIETIES OF NOCTU^J 



Hind wings grey, paler towards the base, a very indistinct transverse 

 row of black dots rather beyond the middle, uniform with those in the 

 fore wings. This insect belongs to the same group as N. neurica, to 

 which it is closely allied. It differs, however, in the following par- 

 ticulars : the size is somewhat larger, the short black basal dash in the 

 fore wing (which does not reach one-fourth the length of the wing) is 

 represented in N. neurica, by an ill-defined, dark, greyish streak, ex- 

 tending to the middle of the wing, and in the latter species there 

 are several conspicuous black dots near the base, towards the costa, of 

 which there is no trace in N. brevilinea. In N. neurica the apical 

 margin in all the wings is plainly spotted with black ; in the species 

 under consideration, this margin is perfectly immaculate, and as an im- 

 portant character, I may mention that the apical margin in N. neurica 

 is more rounded. In the hind wings an indistinct lunule, present in 

 N. neurica, is not found in N. brevilinea. The antennas are darker, 

 and the apex of the abdomen in the male is provided with larger 

 curved appendages " ( ' Entomologist's Monthly Magazine,' vol. i., p. 

 107).

Vol. i., p. 43. Tapinostola elymi, var. Mons. Oberthiir de- 

 scribes and figures a form of this species from the Isle d' Askold, which 

 has a row of black spots in the nervures of the superior wings. He 

 writes of it : "I have figured, PI. ix., fig. 2, of this vol. of the 

 ' Etudes d'entomologie,' an example of T. elymi, taken at Askold on the 

 22nd July, 1878, distinguished from the ordinary type from the shores of 

 the Baltic Sea, by having a row of small black spots on the nervures 

 of the inferior wings. The type from Askold seems also more slender 

 and of a less robust appearance than those from Prussia" ('Etudes d'en- 

 tomologie,' v., p. 71). The figure shows a row of dots not only on 

 the inferior, but also on the superior wings.

Chortodes, St., extrema, Hb. 



Vol. i., p. 47. Chortodes extrema = C. bondii (?) It appears that 

 the question of the identity of Hiibner's extrema, that is of the actual speci- 

 men apart from fig. 412, with bondii w&s suggested many years ago by 

 Dr. Knaggs. Mr. Doubleday then sent specimens of bondii to Professor 

 Zeller, who wrote concerning them : " After an examination of the 

 figures and descriptions, I cannot suppose bondii to be the extrema of 

 Hiibner. Treitschke (' Die iSchniet.' etc., vol. v., pt. 2, p. 316), who 

 saw the originals, says that the cilia, though too darkly coloured, are 

 really dark, as if singed, and adds, that in the least marked specimens 

 there is always a dark dot in the outer (posterior or anterior) margin, 

 which is visible on the outside. Moreover, the whole underside is 

 white, sparingly dusted in the intervals of the prominent veins. I 

 hope that when I am at Vienna I shall see the specimens in the 

 Museum, and be able to inform you of the real difference of these two 

 species." 



Mr. Doubleday then added : " I am rather surprised that these 

 remarks of Treitschke were not quoted by Dr. Knaggs, as, if the
