Beneath much paler, irrorate, without discal marks and with a common 

 shaded line. Expanse, 32 mm. (Quebec. Mr. Bowles." 



The above is Mr. Grote's description and fairly characterizes the 

 species. It is also credited generally to the " Eastern and Northern 

 States," and I have it from the Adirondack Mountains in July. I have 

 also seen a specimen from northern New Hami)shire, but the creature 

 is apparently rare. 



ACRONYCTA PYRALIS Smith, 

 (riate XIII, lig. 12, iiiiile adult.) 



■ Acronycta pyralis Smith, Ent. News, 1895, VI, pi. xv, fig. 1 ; Eut. News, 1896, 

 VII, p. 26. 



Ground color a very dark powdery gray ; head and thorax without 

 distinct markings, but the tip of the collar grayish and the patagiae 

 indefinitely black margined. The primaries have all the ordinary mac- 

 ulation evident, but not sharply defined. Basal line single, black, and 

 marked on the costa only. Transverse anterior line nearly upright, 

 outcurvcd between the veins, black, ju-eceded by a few pale scales. 

 Transverse posterior line widely outcurved over the cell and a little 

 incurved below, usually remote from the center of the wing; black in 

 color, lunate between the veins and followed by a paler gray shade. 

 Snbterminal line obscure, and marked only by an irregular and incom- 

 plete preceding dark shade. There is a series of blackish terminal 

 lanules and a very evident, blackish, somewhat diffuse shade across 

 the median space close to and parallel with the transverse posterior 

 line, somewhat obscuring the reniform. ( )rbicular large, oval, obscurely 

 defined by black scales, with or without a dark central spot, lieniform 

 broad, upright, a little incurved; outwardly a little paler than the 

 ground color, but inferiorly obscured by the median shade. Seconda- 

 ries smoky, with .an indefinite extra-median line and pale fringes. 

 Beneath, smokj'^ and powdery; both wings with an outer line. 



Expanse, 1.24 to 1.30 inches (31 to 34 mm.). 



H<(bit((t.—Gii]si\ry, July 13. 



Two specimens, both females, were sent me by Mr. Dod under the 

 number 31, and this is said to represent his stock. The species is the 

 darkest of all those known to me, resenibliug lithospila in this respect, 

 but quite different in markings. 



This species is allied to dentata with which it is congeneric. It can 

 not remain in Avronycta ; but I am at a loss to place it as yet, and 

 l)refer to leave it here lor the present. 



ARSILONCHE Lederer. 

 Arsilonche Lederer, Noctuinen Europas, 1857, p. 70. 



Moderately stout species, with fine hairy vestiture, rather narrow, 

 somewhat pointed primaries which bear no trace of transverse 

 maculatiou.
