Family NOCTUIDAE. 



Leacauia Haryeyi, Grote, Plate 1, fig. 14, primary wing. 



6 P . — The fore wings are ratlier narrow, with straight costal edge and hardly 

 ohlique exterior margin. They are pale ochrey, with a gray costal shade, 

 which picks out the nervules. A black dot at the extremity of the cell. The 

 median nervure is striped with white scales which extend partially along the 

 median nervules, that are else marked with gray. At base the white stripe 

 broadens below the nervure and is edged inferiorly by a distinct black line. 

 Medially, below median nervure, the submedian interspace is gray limited 

 below by a second curved dark line. A third dark streak edges the median 

 nervure below, between the origin of second and third nervules. Between the 

 fourth and fifth nervules there is a faint interspaceal streak and cuneiform 

 dark marks precede the gray terminal space, which is cut off obliquely to apex. 

 A fine terminal line ; fringes pale. Collar whitish, with a dark bordering line ; 

 tegulae with a white streak. Head, thorax and appendages pale, somewhat 

 olivaceous ochrey. Hind wings smoky, blackish, with whitish fringes, with- 

 out marks. Beneath, pale with powdered dark scales ; nervules dark. Some- 

 times the median nervure on the primaries is darker shaded above on the cell, 

 and the subterminal marks are variably guttate and distinct. 



Expanse, 1.20 to 1.30 inch. Habitat, Buffalo, N. Y., etc. 



A common species in the Eastern and Middle States. It is probably 

 described by Guenee as L. albilinea, Huhier. A reference to Hiibner's 

 original illustration, Zutraege, figs. 337 to 338, of a species with 

 uneven costal edge, pale apical shade and produced apices, from 

 Buenos Ayres, gives abundant reason to reject Guenee's determina- 

 tion, while the assumption that Hiibner is mistaken in his locality, 

 seems gratuitous. Guenee himself doubted his determination of 

 our species, for, referring to some discrepancies between Hiibner's 

 figure and the material before him from the United States, he asks : 

 Serait-ce une espece distincte ? 



To Dr. Leon F. Harvey, of Buffiilo, who is studying this Family 

 of Moths, and whom I thank for his kind personal interest, I dedi- 

 cate this species.
