158 TWENTY- SIXTH REP OUT ON THE STATE MUSEUM. 



the accompanying text the larva is said to be rare, and to feed on 

 oak, willow and wild plum. 



The imago is represented of the size and shape of wings of A. psi 

 figured beside it (with which our A. occidentalis Grote was for a 

 long time confounded), the discal spots are more deeply marked, and 

 the inner third of the primaries is brown, conforming in these parti 

 culars to the features indicated by Mr. Sanborn, as noticed in the 

 Harris specimen. Other marked features are, the brown of the 

 internal margin continued as a median band across the wings, sepa 

 rating the discal spots, and a distinctly defined brown border on the 

 white secondaries. 



A. alni is figured in Wood s Catalogue of the Lepidoptera of Great 

 Britain, pi. 14, fig. 314; and following it, as fig. 315, is A. psi. 



From the above, I think it highly probable that our species will 

 prove to be identical with A. alni of Europe; if not the same, it is 

 certainly very closely allied to it. 



The figure of Acronycta funeralis Gr.-Rob. (Proc. Ent. Soc. Phil., 

 vi, pi. 3, f. 8), resembles very closely that of A. alni above referred 

 to, differing mainly in the diffused border of its inferiors, their fringe 

 cut with black instead of simply dotted, and in the absence of the 

 submarginal black streak of the superiors behind the cell. Mr. Grote 

 informs me that he has seen A. alni, and that A. funeralis and also 

 A. connecta Gr. (Bull. B^lff. Soc. Nat. Sci. ; I, p. 79) resemble it.* 



Acronycta hastulifera (Sm.~Abb.\ 



Larva feeding on horse-chestnut ; two inches long, covered with 

 gray or light red hairs. Body cream-color, with two dark interrupted 

 stripes on each side, and two on the back. Head, feet, anal seg- 



* To the kindness of Mr. Sanborn I am again indebted for a second visit made by 

 him to the Boston Soc. of Nat. Hist., in compliance with my request for a critical 

 comparison of the Harris specimen of &quot;A. Americana 1 1 with the description and 

 figure of A. funeralis Gr.-Rob., and for information just received from him, that the 

 two are, without doubt, the same species. 



Now that both the larval and perfect stages of A. funeralis are described and 

 figured, a satisfactory comparison may be made with A. alni, to determine the ques 

 tion of their identity which has arisen from the marked resemblance in the repre 

 sentations of their unique larvaB. 



The habitat of A. funeralis is evidently quite an extended one. The larva ^has 

 been taken by Mr. C. V. Ililey, at Portland, Me. , on elm ( Tllmus Americana], and by 

 Prof. Bessey, as Mr. Riley informs me, at Aines, Iowa. Mr. Grote s type is from 

 Ohio.
