A. hamamelis, Gu6n. 

 A specimen, labelled by M. Gu6nee, of this species evidently re- 

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

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

 (bote's collection and therefore quite distinct from A. clarescens ofGiote, 

 which belongs to another group in which the dagger mark is well defined. 



Acronycta noctivaga, (Irote. 

 The A. longa of Walker is a synonym of this species and quite 

 distinct from Guc-nee's insect of which, unhappily, we do not possess the 

 type but which appears to be a form of J. brumosa =fiersuasa. 



Acronycta subochrea, (1. >.\: R. 

 I cannot distinguish this from the type of J. impleta, Walk., which, 

 although broken, is in perfectly recognizable condition. 



Acronycta hilus, (Irote. 

 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 11 Smith. 



Acronycta 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, (bote, 

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

 of his specimens 1 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. (irote. 

 Mr. Butler says further on this subject in the letter above quoted : •'] am 

 very doubtful about the identity o{ A. exults [qy. exilis ?] 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 ami the pattern of the two forms is identical : A. c.xulis 

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

 end ofdiscal 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 c.xulis 

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