A. hamamelis, (iuen. 

 A specimen, labelled by M. Guenee, of this species evidently re- 

 presents a dark form of his A. darcscens (one of the types of which we 

 also possess, as noted by him). A. clarescens is the 'A. hamamelis of 

 (jrote's collection and therefore quite distinct from A. clarescens ofGrote, 

 which belongs to another groii]) in which the dagger mark is well defined. 



Acronycta noctivaga, Chote. 

 The A. longa of Walker is a s\nonym of this species antl quite 

 distinct from Guenee's insect of which, unhappily, we do not possess the 

 type but which appears to be a form oi A. hrtimosa =z pcrstiasa. 



Acronycta subochrea, G. & R. 



I cannot distinguish this from the type o{ A. implcta, Walk., which, 

 although broken, is in perfectly recognizable condition. 



Acronycta hilus, (hole. 

 This appears to me to be a small form of A. modica. Walk. ; it is 

 however paler on the under surface and on the upper surface shows more 

 rufous-brown in the discoidal spots of primaries. I am not usually re- 

 garded as a lumper of species, but I should certainly hesitate to consider 

 it distinct ; it may be. 



Notes on Preceding Paper. 

 By John B. Smith. 



Acronvc/a hilus, Grt. , does not seem to be described ; no description 

 is known to me at least. I wrote Mr. Butler on the subject asking whether 

 he knew of a description ; his reply is : "With regard to A. hilus, Grote, 

 1 know of no description of the species, but as Grote had so labelled one 

 of his specimens I concluded that he did know of it, and that you, in 

 America, would be likely to know of it also." 



Modica, Walker, has been dropped from our Lists by Mr. Grote. 

 Mr. Butler says further on this subject in the letter above quoted : "I am 

 very doubtful about the identity of^. exulis [qy. c.vilis ?] with J. modica; 

 it is possible that they are distinct and, in any case, they represent at least 

 two well marked types of one species ; at the same time Grote did not 

 possess A. modica and the pattern of the two forms is identical : A. exulis 

 is smaller, has paler primaries with a little more brown suffusion within 

 end of discal cell ; but the two specimens from Grote s collection differ in 

 tint of primaries, the type being paler than the second example ; therefore 

 I say that I would not myself venture to separate it as a species." 



Mr. Butler's letter leaves it in doubt what relation hilus and exulis 

 bear to each other ; both seem to be hardlv distinct from modica.
