402 THE CANADIAN ENTOMOLOGIST. 



the Red Deer River locality — now known by the name of an 

 adjacent post office, Dorothy — on July 23rd, 1907, which I have 

 compared with both types in Smith's collection. In that collection 

 also are a pair from Bozeman, Montana, Aug., 1908, and a female 

 from Westbourne, Man., Aug. 3rd, 1908, from Mr. J. B. Wallis. 

 Sir George Hampson gives figures from coloured drawings sent him 

 of both types. That of flavistriga is most like my specimen, but 

 shorter winged. That of extensa is in accordance with my notes 

 on that type, which is browner than any of the rest I have seen, 

 though when I saw it it was greasy and probably discoloured. 



600. Hadena castanea Grt. — This name stands wrongly in our 

 lists as a synonym of pluviosa. The type of the latter is in the 

 British Museum and is a very badly worn specimen from Van- 

 couver Island. It is, as Hampson lists it, the species well known 

 as arctica Bdv., which I believe was described from Labrador. A 

 type of castanea is in the British Museum from California, and, 

 according to Smith's Catalogue, there 'is another in the Tepper 

 collection. That of cymosa from Washington Territory is in the 

 British Museum also, and is the same as the type of castanea there, 

 and distinct from arctica. Castanea is sienna brown, and cymosa 

 fuscous brown, whilst the "ab. 1" of Hampson is a variegated 

 form with pale shades in the subterminal area. Castanea occurs 

 on Vancouver Island, often apparently in considerable numbers. 

 Arctica occurs there also, but less commonly. Whilst I think it 

 improbable that the two are one species, the variegated form of 

 castanea sometimes resembles arctica so very closely as to make 

 separation a matter of the very greatest difficulty, if not occasionally 

 impossible. 



In the Kootenai List Dr. Dyar records .under pluviosa three 

 specimens from Banff, Alta., July 21st, Aug. 11th and Sept. 10th, 

 1904, adding: "Apparently distinct from arctica Bdv., but very 

 close to it." I did not see the specimens when at Washington, 

 but must assume that he took the variegated form of castanea, and 

 therefore so record it. I have not found the species amongst 

 specimens sent me from time to time by Mr. Sanson. 



601. H. loda Strk., syn. albiserrata Sm. Mr. Sanson has taken 

 two males of this species at light at Banff, on Sept. 2nd, 1908, and
