the head and thorax very pale ochreous or whitish, the ground colour 

 of fore-wings whitish tinged with grey or ochreous, and a fascia rising 

 on the inner margin of fore-wings a little before the middle, and crossing 

 the wing nearly parallel with the hind margin. Briefly I would de- 

 scribe them as follows : — 



Suhroseana, Haw. Fore-wingg broad, costa and hind margin rounded. Gronnd 

 colour whitish-ochreous, tinged with reddish beyond the middle, and with the 

 entire apical portion reddish-brown. Fascia broad, reddish-brown, not very 

 oblique, and barely touching the costa. Apical fringes dull ochreous spotted 

 with reddish-brown. Hind-wings dark grey. 



Heydeniana, H-S. Fore-wings broad, costa and hind margin rounded, v/hitish, 

 delicately reticulated with grey, and with a faint rosy or pinkish suffusion, 

 especially towards the apex. Fascia greyish-brown, slender, slightly inter- 

 rupted and bent back near the costa. Apical fringes very sliort, ochreous 

 dotted with grey, and with a distinct darh line along their base. Hind-wings 

 pale grey. 



In this species I cannot entirely confirm Mr, McLachlan's descrip- 

 tion. The rosy suffusion is very distinct in my specimens, but totally 

 different from the rich orange-red or reddish-brown of the apical portion 

 of the wings of s\Llroseana. 



Ciliella, Hiib. Fore-wings long and narrow, and much pointed at the apex. Costa 

 and hind margin nearly straight. Whitisli-ochreous, fascia very oblique, 

 parallel indeed with the hind margin, and barely reaching the costa ; yellowish- 

 brown or reddish, varying greatly in colour and distinctness. Beyond it, on 

 the inner margin, and before the anal angle, is a triangular spot, and along 

 the hind margin an indistinct band, both of the same colour as the fascia. 

 Apical fringes very long, dull yellow. Hind-wings pale grey. 



Degreyana, McL. Fore-wings long and narrow, margins nearly straight. Greyish- 

 white with a pink tinge, which becomes very decided towards the apex. 

 Fascia reddish-brown, I'crj/ slender, indistinct beyond the middle of the wing, and 

 becoming obsolete before the costa. Apical fringes binght ochreous. Hind- 

 wings dark grey. 



Thus suhroseana and Heydeniana have broad wings and rounded 

 margins, the former having an orange-red apex and spotted fringes, 

 and the latter very short fringes with a dark line at their base. 



Degreyana and ciliellahsiYe long narrow wings with straight margins, 

 the former a slender abbreviated fascia and pink apex, and the latter a 

 broad entire fascia and marginal band, both parallel with hind margin. 



Finding last spring that the supposed suhroseana which I have 

 been in the habit of occasionally taking was likely to prove a novelty 

 {Heydeniana), I resolved to work carefully for it, and, if possible, take 

 a lot for my friends, this being apparently practicable, since it appears
