" spot, composed of two parallel Hues, the extreme hinder margin with 

 " a slender black line ; cilia fuscous, with black tips ; posterior wings 

 " fuscous, cilia paler " (111. 4, p. 98) agrees tolerably well with three 

 specimens in Mr. Doubleday's collection, which were named ohscurana 

 by Stephens himself, but it does not agree with that of Wilkinson, 

 which, as I have already said, refers to the previous species. In these 

 three specimens the fore-wings are narrower than in gallicolana, the 

 costal streaks shorter and less distinct, a)id the dorsal blotch is decidedly 

 flatter and more oblique as well as more dusky in colour. A specimen 

 (agreeing precisely with these) is in Mr. McLachlan's collection, 

 taken by him at Darenth "Wood.- 



Very little seems to be known of this species. Professor Zeller 

 thinks it very close to his suspectana from Livonia, but will not venture 

 to unite them ; Dr. Wocke ignores it altogether, from which I imagine 

 that he could make nothing of it, Foedlsca ohscurana, H.-S., which ap- 

 pears in his list, being evidently a different species allied to Halonota 

 trigeminana. 



In Mr. Doubleday's collection there is yet another species which 

 has been mixed with ohscurana. It is exceedingly close to motacillana, 

 Zell., but differs in the form of the dorsal blotch, and in the colour of 

 the hind-wings, which, in motacillana, are uniformly blackish. It does 

 not seem advisable, however, to describe it as a novelty, unless more 

 specimens can be obtained for comparison, since it is just possible that 

 motacillana may vary sufficiently to include this specimen. 



I wish to draw the especial attention of collectors in the woods 

 of the south of England to this small group of excessively rare species, 

 the true limits of which it is difficult to define, from the scanty 

 materials obtainable. 



Semasia JVosherana, 8chiff. — M. Jourdheuille says that the larvse 

 are to be found of all ages at once feeding on the inner bark of fruit 

 trees, and assuming the pupa state in their burrows. 



Semasia Janthinana,'Du'p. — According to M. Jourdheuille's calen- 

 ' dar, the larva feeds in decaying berries of hawthorn, but hibernates in 

 a silken cocoon on the surface of the ground. Professor Zeller tells 

 me that this species is very rare in Grermany. 



Semasia rtijillana, Zell. 



Semasia nanana, Tr. — M. Jourdheuille states that the larva feeds 

 in leaves of fir, assuming the pupa state among them in a whit-o web.
