NOCTUAE. 



Apiitela Iladclifrci, n. s. 



$ . — Ant(>nnae simple ; the first ami third palpal joints wlilte, the middle 

 brown; thorax in front marked with black at the sides. Head above, tliorax 

 and collar, like- primaries in color, unmarked. Primaries of a frosted silver 

 gray, the basal black streak extended outwardly to the t. a. line, bordered 

 above with white. T. a. line geminate, divaricate, inner line the darkest, dis- 

 tinct, outer line faint, inner line better marked at the center of the wing, 

 Avith a costal tooth. Basal half line evident. T. p. line, commencing at the 

 casta nearly above the reniform spot, curves outwardly to a point beneath and 

 beyond the reniform. The outer component line is black, the inner faint; 

 the line itself is obsoletely angulated superiorly. The characteristic mark of 

 this genus is well indicated above internal angle, crossing the t. p. line and 

 accompanied beyond the line with a slight black shading. The subterminal 

 line is a faint, broad, irregular streak. The reniform spot only half margined, 

 and tliat the inner one with black; the orbicular spot oval, with a black mar- 

 gin and an almost white annulus Avithin that; the costa faintly dotted; 

 fringes concolorons. 



Beneath the primaries are fuscous, the inner margin of the wing nearly 

 white, the t. p. line very distinct, oiitwardly angulate over the median nerv- 

 ules. The secondaries above fuscous, approaching to black, fringes white; 

 beneath, of a mottled white; a black dash near the base; the discal spot 

 black, prominent, the outer line strongly marked, obscurely denticulate, fringes 

 concolorous. 



Expanse, 39 m. m. Habitat, Massacliusett.s. 



This species is allied to A. hasta, differing from it iu the more 

 evenly marked t. p. line, the larger orbicular spot, the want of a 

 discal spot between the stigmata, and from all allied species in tlie 

 absence of tlie streak opposite the cell. 'J'he peculiar frosted gray 

 color is shared by no other species.
