60 THE CANADIAN ENTOMOLOGIST. 



and then at right angles directly to the inner margin, where it is much 

 nearer to the base of the wing than it was at its point of origin on the 

 costa, and the basal blotch is not nearly so conspicuous as in fluctuata. 

 Finally, the outer margin m fluctuata is less rounded than \n planaia. 



These differences may appear slight, but they seem to be constant ; 

 and, in view of the fact that the two insects inhabit different continents, I 

 think that the new name is justified. I hove compared 19 European with 

 numerous American specimens, and I have not found any intermediate 

 forms, 



6. Aplodes unilinearia, n. sp. — Expanse, 32-33 mm. 



This species may be best described by comparing it with the known 

 species of the genus. A. brwinearia is brown, so cannot be confused 

 with any other species. A. ruhripoiitaria, Pack., Darwiniata, Dyar, and 

 two manuscript species of my own intennediata from Nevada, and Cali- 

 for7iica from California, all have the abdomen in the male with white 

 dorsal spots circled with red, and have the extradiscal lines on the hind 

 wings extending from margin to margin. 



In A. mimosaria the lines are also continuous, but the abdomen has 

 not any red spots. In A. Hudsonaria and in the present species, the 

 abdomen agrees with mimosaria, but the outer line on the hind wings does 

 not reach the inner margin of the wing. The difference between Hud- 

 sinaria and utiilinearia is that in the males of the latter the inner lines on 

 all the wings are obsolete, and the outer line on the hind wing in both 

 sexes is further from the base of the wing and takes a different course, 

 for while the same line in Hudsonaria would, if produced, reach the base 

 of the wing, in uni/inearia it would touch the middle point of the inner 

 margin. A. uniliucaria is a trifle larger than Hudsonaria, but not quite 

 so large as Dariviniata. Mr, Cockle brought with him four specimens 

 taken at Kaslo and dated 6th August, 1907 (a female), and 7, 14, 21 July, 

 1907 (3 males). The first three he retains in his own cabinet, and the 

 last named is in my collection. 



Two female moths from Victoria which I recorded (in Can. Ent., 

 XXXVI II., 206) as i)robably A. Hudsonaria^ are A. unilinearia. The 

 Aplodes Junctolinearia, Gra'f, is evidently near to Hudsonaria, but Hulst 

 says it is an Anaplodes, in which case it will readily be separated by 

 its lack of the hair pencil on the hind tibia; of the male.i.
