Acronycta exilis Grt. and A. modica Wlk. 



In the monograph I united these two forms. After seeing 

 the types, in 1900, I admitted their possible distinctness (Can. 

 Ent. XXXII, 335). Hampson describes and figures them as 

 separate. After looking over the series before me, I am as 

 undecided as ever and cannot find a single reliable character 

 on which to base two series. There are always some three 

 or four examples that will not fit better into one series than 

 into the other. With the British Museum material only at 

 hand, the two forms seem distinct enough ; exilis being smaller, 

 paler and apparently rare. 



Acronycta inclara Sm. 



This name was proposed by me in 1900, Can. Ent. XXXII, 

 335, for the species theretofore known as hamamelis in collec- 

 tions, and it has no type. There is a considerable range of 

 variation in this aggregation, and it may be convenient to fix 

 more definitely the one to be covered by this name. Hampson 

 in his Catalogue Vol. VIII, p. 8, describes, and on PI. CXXIV, 

 28, figures one of the common types, and this may be accepted 

 as the type of the name. 



There seems almost no end to the variations in this species, 

 and many of these seem local ; but there is on the whole a 

 characteristic facies that distinguishes a series, and that is 

 not well brought out in the figure. There is an obscure 

 streak crossing the s. t. line in the sub-median interspace, 

 beginning a little beyond the middle of the wing. From the be- 

 ginning of this line a triangular dusky shade extends above it, 

 reaching the outer margin at vein 7 and forming a darker 

 triangular patch, which is traceable in every specimen and 

 characteristic in a large series. There are variations in ground 

 color from white to gray, mossy shadings, brown shadings 

 and yellowish shadings, and no end to the differences in con- 

 trasts; but this one feature remains throughout. 



I have had from Mr. Heath, at various times, nearly a 

 dozen examples of what seems to be a local race, at least, 

 and which he is inclined to consider specifically distinct from
