THE CANAniXN KNTOMOLOGIST. 75 



(>r t) pical form aie recorded from llie east. Ilyd. furcdta is more 

 heavily speckled than quinqnefaiciata Pack., and the extradiacal line is 

 much narrower after it leaves the costa than in quijiqiiefasciaia, where it 

 is heavy and broad the entire distance. I saw a ^ in Dr. Barnes' 

 C(3ihciion from Arrowhead Lake, B. C., July r6-i8, which seems nearer 

 to iyyxzdXfurcata than anything I have seen. It is not unlike German 

 and Iceland specimens in my collection. There seems to be some doubt 

 ill the Rev. Geo. \V. Taylor's mind whether we get the \xwt furcatd here, 

 and I am inclined to agreed with him, yet tliey run so clo-e in markings 

 as to be difficult to separate, and I shall leave them as listed until I can 

 study the genitalia and compare the life-histories, which must be done to 

 complete my work, as it is, in a way, superficial. 



Var. (a) elutata Hiib., Schmett Eur., 224 (post 1797). This is a 

 synonym o\ f areata Thunb. according to Mr. Proul's and my own vi.ws, 

 and should be dropped from our lists. 



Var. (a) quinquefasciata Pack., Proc. Boston Soc. Nat. Hist, XllI, 

 p. 397, 1871, Monog. p. 100, 1876. 



Short palpi, smoky bands, clear discal space. 



This may be the North American form oifurcaia if we do not get- the 

 FLuropean here, and it is a variety at any rate. The figure in Packard's 

 Monograph, Plate VIII, fij. 36, is exc llent. There is an error in fig 35. 

 as this is x\o\furcata nor a variety of it, but a green form o{ mibilofasciata 

 Pack., which is in his collection and which I examined. T.u differences 

 between quinquefasciata diudfurcata are in the former having a clear gray 

 mesi il ^pace where the latter is irrorated, in the smoky bands of the former 

 and form of the extradiscal or fifth band from body. Dr. B.irnes has a 

 c^ from Arrowhead Lake, Aug. 24-31, in which the bands are bluish 

 instead of smoky, otherwise it is like quinquefasciata. 1 have seen a 

 similar form from Calgary, July 24. This var. quinquefasciata is found 

 probably through the whole Northwest, and does not vary greatly. Mr 

 A. J. Croker, of Victoria, B. C, has a specimen from there, taken July 

 27, 1909, in which the white round spot of typical /«r<r(7/a appears in the 

 middle of the fifth band of fore wing, near the inner margin. 'I'he general 

 colour is smoky-gray, and resembles a variety of speciosata Pack., and 

 would be hard to separate were it not for the long beak-like palpi of the 

 latter. The ground colour varies from greenish to reddish, the specimen 

 1 have from the Rocky Mts. seems more brownish. In the European 

 var'eties oifurcata the extradiscal line tapers to a narrow line near the i nner
