marked, the secondaries dusky. P'our other examples of fnodica are 

 broader winged than exilis. Based upon these specimens only, the two 

 names would seem to refer to distinct species ; but, in the series before 

 me when I wrote, I failed to find a reliable character to separate them. 



Acronyda spinigera, Gn., type ; A. Harveyana, Grt., type. These 

 are identical, lliere seems to be no reason for doubting the authenticity 

 of the type label on Guenee's species and, as pointed out in the 

 Revision, the description is thoroughly applicable. 



Acronyda ovata, Grt., type. Another type specimen is in the 

 collection of the American Entomological Society. 



Acronyda alharnfci, Grt., type. The type of IVaikeri, Andrews, is, I 

 believe, in the possession of Mr. John Akhurst, of Brooklyn. 



Acronyda grisea, Wlk., type. The type o'i piidorata. Morr., is in 

 the Tepper collection, now in the possession of the Michigan Agricultural 



College. 



Acronyda lobelia^ Gn. The type is a small and not very character- 

 istic specimen without fringes. 



Acronyda thoracica, Grt. The type is a female, placed in the 

 collection under the lobelke label as identical with it ; but the species are 

 distinct. 



Acronyda patipercula, Grt. The specimen is of the larger form of 

 the species. 



Acronyda falcula, Grt., type. Two examples of grisea are errone- 

 ously associated with this. 



Acronyda par allela, Grt., type. 



Acronyda quadrata, Grt. The type is a female. 



Acronyda conneda, Grt. The type a male. 



Acronyda Radcliffei, Harv. Marked " type " in Mr. Grote's hand- 

 writing. 



Merolonche spinea, Grt. The type is a female. Another example, 

 also labelled "type," is in the Hy. Edwards collection. 



Acronyda lanceolaria, Grt., type ; Acronycta insoliia, Grt., type. 

 The former is a good example, the latter a very poor male : lanccolaria 

 I had seen at the time of writing the Revision ; but insolita was then 

 unknown to me. During the winter of 1899- 1900, Dr. Dimmock sent me 

 a few specimens from Massachusetts for determination ; among them 

 was insolita, and, much to my surprise, examples indicating that it was a 

 very dark form of lanccolaria. The two extremes are totally unlike — 

 very pale ashen or whitish gray on the one hand, almost black on the 

 other, yet when the black overlay of insolita is removed, lanccolaria 

 appears and, of an example now in my collection, it is almost impossible 

 to say where it should be placed. 



The material is too scant to make the reference positively ; but it is 

 a little problem for our New England friends to solve by breeding. The 

 larva has been found by Mr. Kirkland and is described on p. 172 of the 

 Revision. It feeds on Willow, Compionia and Gaillardia.
