The species belongs in tlie binotata group and is closely allied to 

 susquesa Sm., but differs in the distinctly serrate antennae and the 

 course of the t. p. line which is less bent around cell and more closely 

 approximate to reniform; the color also is dark gray instead of 

 brownish. 



Agroperina popofensis Sm. 



This species, described as a Luperina (1900, Proc. Wash. Acad. 

 Sci. II, 492), should be transferred to the genus Agroperina; an ex- 

 amination of the type shows it to be very close to indela Sm. of which 

 it is probably only a northern race ; we have a series from Kodiak, 

 Alaska. 



ACRONYCTA ARIOCH Stkr. 



In our notes concerning this species in Contr. Ill (3), 166, we 

 have made a rather grave error, confusing the species evidently with 

 A. gasta Stkr.; it is this latter species which resembles so closely A. 

 megacephala from Europe as to lead to our suggestion that the speci- 

 men serving as type bore a wrong locality label. A. arioch, which is 

 related to oblinita A. & S. should be reinstated on our lists, whilst 

 gasta may be dropped ; the type specimen was received by Strecker, 

 according to information received from Mr. Wm. Gerhard of the 

 Field Museum, from a Chicago collector, Paul Vollbrecht, a German 

 by birth, who might accidentally have mixed a European specimen 

 with those collected in the vicinity of Chicago by himself. 



Merolonche dolli sp. nov. (PI. XVI, Fig. 6). 



S antennae lamellate; head and thorax hairy, dark gray; collar with a 

 central black vertical line ; thorax with two central dark lines, upper and lower 

 edges of patagia black ; primaries dark gray, heavily black shaded ; a minute 

 black dash on costa at base followed outwardly by a pale patch representing 

 the filling of an obsolete subbasal line; a distinct black basal dash below median 

 vein reaching to t. a. line ; this hne geminate, very distinct due to the pale fill- 

 ing, with three prominent outward angles, below costa, below median vein 

 and above inner margin ; median space largely blackish with a pale oblique 

 costal patch, descending between the spots almost to t. p. line ; orbicular small, 

 round, white centered ; reniform obscured by black shades, rather broadly 

 lunate ; t. p. line very distinctly dentate, geminate, pale-filled, bent out around 

 cell and incurved in fold ; s. t. line represented by a few intravenular dark 

 marks on a paler ground color ; secondaries dull smoky with whitish fringes.
