the inner border, by a gentle, rather regular curve, which follows the 

 outer border of the cell; besides, there is a small roundish patch at 

 the extremity of the cell itself, separated from the part outside by 

 the nervures. On the hind wings it is of less extent, its interior 

 border passing in a broad sinuous curve from the tip of the costal ner- 

 vureto the middle of the lower median interspace, where it terminates 

 abruptly; the band is broadest beyond the cell, reaching two-thirds 

 the distance from the outer border to its outer extremity; the fringe 

 is concolorous, but its basal half is black below the middle subcostal 

 nervure. Beneath, both wings are uniform, immaculate, very pale 

 silvery buff. Expanse of wings 70 mm.

This butterfly is undoubtedly most nearly allied to A. Neleis 

 (Boisd.) Butl., but differs from it in the coloration of both surfaces, 

 the black edging of the fore wings and the secondary mealy patch 

 of scales in the cell of the same wings.

The following paper was read : — 



List of a Collection of Texan Noctutd^e, with Descrip- 

 tions of the New Species. By H. K. Morrison. 



The collection on which this paper is founded was made in the 

 vicinity of Waco, Texas, by Mr. Belfrage, and is now in the posses- 

 sion of the Peabody Academy of Science, at Salem. 



The opportunity of determining it we owe to Dr. A. S. Packard, 

 Jr., and we only hope we shall succeed in working it up as well as he 

 has the Geometrician from the same locality. 



We have thought best to publish a list of all the species, as some of 

 them have not been before recorded from Texas ; the generic position 

 of others has been changed, and finally, they are all provided with 

 the date of capture, which is usually lacking in similar collections. 

 There are comparatively few new species, as material from the same
