in this connection I might mention that while the fore-tibial spines are quite 

 clearly ^een m European specimens of spcciosa and its race arctica. in several 

 North American specimens from Mt. Washington, N.H., before me I have been 

 quite unable to detect them although the genitalia present no differences which 

 would indicate specific distinctness. 



It is further of interest to note that Aplcctoidcs Butl. may possibly fall 

 to Ptcroscia Morr. (1874, Proc. Bost. Soc. Nat. Hist., XVII., 155). This 

 genus was based on the single species atrata Morr. from Mt. Washington, N.H., 

 a species omitted by Hampton in his catalogue and wrongly included under 

 Agrotis in the Barnes and McDunnough Check List, 1917, on account of the 

 superficial resemblance to the unimacula group. An MSS. note by Dod, who 

 carefully examined the British Museum specimen, states that the species looks 

 like an Alpine Aplectoides and is closely related to spcciosa; this reference I 

 thoroughly agree with after an examination of a ? specimen recently received 

 by the National Collection from Larder Lake, Ontario, and which seems to be 

 an undoubted atrata. If condita and atrata, the types of the two genera in 

 question, prove congeneric, Ptcroscia will have priority. The correct generic 

 relationships of the entire Agrotid group require however a much more detailed 

 study than I now am able to give and I shall confine myself in the present paper 

 to a few remarks on the various species.

I have recently recorded (Can. Ent. liii., 84) the receipt of a very fine male 

 specimen from Hopedale, Labrador, which is now in the National Collection, 

 through the kindness of Dr. E. M. Walker. It matches so excellently the figure 

 given in Seitz, Macrolepidoptera, Fauna Palaearctica, Vol. III., PI. XIII. k, that 

 even without European material for comparison I feel reasonably sure of the 

 identification. A single worn specimen labelled Labrador is in the Barnes 

 Collection ex. Coll. J. Doll, and very possibly was the one examined by J. B. Smith 

 in his Agrotid revision, as it is evidently from a German collector and has 

 had a portion of the left clasper removed, as was Smith's custom. Mr. Bowman
