THE CANADIAN ENTOMOLOGIST. 77 



is deeply suffused with red, and sometimes has the typical white spot near, 

 outer portion of fore wing, but always has narrow mesial band. I imagine 

 this variety is not very commonly met with, as I have seen only short 

 series -and mostly from California. 



Var. {V.) per id at a Swett, Can. Ent., Vol. XLII, Aug, 1910. 



Short palpi, suffused. 



This is the smoky, suffused form oi fur cat a Thunb. The type sj^eci- 

 men is speckled with green, but probably in si)ecimens not so perfect, the 

 green colouring may not be so prominent. This is related to var. 

 infuscata Stgr., of Europe, and holds the same position, only it lacks the 

 smoky-brown of the Iceland specimens before me and is more like a 

 melanic form than the European. The bands are as in typical fiircata^ 

 only the basal is broader.

Short palpi, greenish, white mesial space. 



Mr. G. W. Taylor, of Wellington, B. C, first separated this variety 

 from the genus EncJioria Hulst, and placed it correctly as a Hydriomenid, 

 but stopped tliere (Ent. News^ p. 310, July, 1907) Where to place it is 

 the next question. It has the short palpi, so will go in the short palpi 

 group, and remembering \\-\?ii fu?'cata Thunb. has a white-banded form in 

 Europe, it seems not unreasonable to suppose this is the white-banded 

 variety of our species. I so place it according to pal[)i and colour scheme, 

 and I notice Mr. L. B. Prout does the same in his article, Ent. Record 

 (London), Vol. IX, p. 84-87, April, 1897, and was the first to so place it. I 

 did not put it there on that account, but because of the relationship to the 

 white-banded/z^j-t:^ undata Donov. of Europe, which it somewhat resembles* 

 the only difference being the course of the extradiscal line of fore- wing, 

 which runs out almost to outer border at vein 4, while this does not occur in 

 the European form. Thus, aibifasciata Pack, becomes a variety oi furcata, 

 and in this I believe I am quite correct, as the white mesial space would 

 show. This colour variety may be caused by its food plant, as \2iV.fu5co- 

 undata Donov. is said to be produced by feeding on the bill-berry, but 

 there is no record of the food-plant of aibifasciata so far as I know Rev. 

 G. W. Taylor and Mr. Grosbeck both suggest that refiata Grote and 

 abacta Hulst may be synonyms oi aibifasciata Pack., but after comparing 

 t\ pes with specimens in my collections, there are differences which I will 

 point out later in the revision. On page 310, July, 1907, EiU. News,
