interior line is oblique, faintly indicated by a series of spots, the 

 largest on the costa and inner margin; the median shade twice out- 

 wardly dentate, very distinct above, obsolete below ; the portion of 

 the wing from this shade to the exterior line above the median ner- 

 vure is black, with the exception of a large, irregular, costal spot of 

 the prevailing color ; the exterior line is black, continued and den- 

 tate, depressed opposite the cell, then produced, and afterward ex- 

 tends obliquely to the inner margin ; just below the costa, and above 

 the inner margin it is thickened, forming blackish spots; beyond this 

 line there is a large, triangular, blackish spot resting on the margin; 

 the subterminal line whitish, indistinct; an interrupted black line at 

 the base of the short fringe. Posterior wings light gray, with a suf- 

 fuse discal dot and a distinct median black line; fringe concolorous. 

 Beneath whitish; on the anterior wings the markings of the upper 

 surface are partially reproduced; on the posterior the median line is 

 black and very distinct, and there is a blackish suffused spot on the 

 costa. 



Hab. Waco, Texas. 



Allied to the European perla and muralis, but our species is a 

 smaller, more compact form, approaching in size and markings the 

 larger species of Taraclie. 



3. Agrotis Morrisoniana Eiley. 



This species will be described at length by Prof. Riley, who has 

 bred it for several years, and is acquainted with its larval and pupal 

 stages. In the Texan specimen the antennas are strongly pectinate ; 

 the orbicular spot is small and distinct; the reniform spot is of the 

 normal size ; all the nervures and their branches are accompanied by 

 contrasting light shades ; the terminal line is preceded by a series of 

 black cuneiform markings ; posterior wings whitish, with a distinct 

 discal dot and faint terminal band. 



4. Mamestra innexa (Grote). Perigrapla innew Grote. 

 Bui. Buff. Soc. Nat. Sc, Vol. n, p. 123. 



We are unable to understand why Mr. Grote places this species in 

 Perigraplia, when it does not possess any of the generic characters 

 (except the hairy eyes) laid down by Lederer; the antenna? are not 

 pectinate, the collar is neither cut out, nor preceded by a longitud- 

 inal prothoracic crest, and there are no angular projections on the 

 sides of the thorax. 



M. innexa is closely related to Dianthcecia meditaia, also described 

 by Mr. Grote. These species agree in size, in the disposition of the
