between the two, but decidedly tending towards discolor. A combina- 

 tion of discolor and punctirena would make paleacea in everything 

 except colour, and the supposed distinctness of the latter from each 

 is based solely upon my confidence in the distinctness of the two 

 former from each other. Dr. Dyar, in his Kootenai list, refers those 

 specimens from Kaslo having the dark spot in the reniform to paleacea, 

 those lacking it to "var. discolor, Walk." As before pointed out, my 

 use of the names discolor and iiifuinata are merely tentative. Sir 

 George Hampson tells me that iiifumata is '• a gray-brown form," and 

 though he not long ago expressed his opinion to me ihut punciirena was a 

 synonym of infumata and discolor probably distinct, he has since told me 

 that he considers all four names to refer to one species. Of the pub- 

 lished figures of the three species which I have had the opportunity of 

 examining, that in Newman's "British Moths" has not as well developed a 

 dark spot in reniform as paleacea usually seems to possess, nor as sharply 

 angulated a t. a. line. I have, however, specimens with a blunter angle, but 

 not with such a constricted, though really a fainter dark spot. As there is 

 no colour guide, it would be quite excusable to say that the figure com- 

 bined all the characters of punctirena. But constriction of the spot is a 

 variation which in all probability occurs in the European species, as it 

 certainly does in punctirena, which in that ])oint then approximates an 

 occasional partially developed spot in discolor. In Barrett's "Lepidop" 

 tera of the British Islands," Vol. V, pi. 223, figs. 2 and 2a, though the 

 dark spots are well developed, the t. a. lines again, in both figures, have a 

 blunter angle than seems usual. But the even, unicolorous appearance of 

 both primaries and secondaries at once bespeaks /rtr/i?rtrf(;. The merest 

 glance at Dr. Holland's pi xxvi, fig, 32. gives the immediate impression 

 of European paleacea, exactly, and in every detail. The uniform, slightly 

 orange-yellow primaries, sharply angulated t. a. line, concolorous discoidals, 

 except for the typically well developed dark dot, and the clear immacu- 

 late secondaries, combine to make such an excellent representation of 

 the Old World species, that I will be bold enough to assert that it actually 

 does represent paleacea, Esp , and is therefore correctly named. But I 

 have so far not seen the species from North America, and I seriously 

 doubt its being a North American specimen. I asked Dr. Dyar his 



opinion of the figure, and he replied: ''I cannot match Holland's figure 

 in my American specimens, though I have about a hundred of them. 

 I have but two Euro]:)ean sj^iecimens, yet one of them is the exact match 

 of the figure." The figure of the type oi punctirena in Can. Ent. XXXH,
