THE CANADIAN ENTOMOLOGIST 351 



(pi. VII T, fig. fi7) which is in the Museum of Comparative Zoology, 

 and undoubtedly represents the type, is the bright, red-banded 

 form with gray outer margin to the fore wings. Hulst (Can. 

 Ent., \"ol. XXXII, p. 104, 1900) described a very similar form as 

 Xanthorhoe {Hydriomena) amorata from two specimens. Dr. 

 Dyar (Proc. Ent. Soc. Wash., vol. VI, p. 223, 1904) refers Hydrio- 

 mena amorata Hulst, male and female, to defensaria Guen. Mr. 

 J. Grossbeck (Ent. News, pp. 147, April, 1907) states that there 

 are two forms, probably both females, and although he refers 

 both of these to Xanthorhoe (Peirophora) he retains the female 

 with the bright, red, central band as the var. amorata Hulst, in 

 view of the fact that it was so distinct. Evidently Dr. Dyar 

 was in error when he said "male and female. " In this var. amorata 

 Hulst, the fore wings have a bright, red-brown, central band and 

 a normal gray, outer border. I see no reason why the name 

 amorata Hulst should not fall before the older name californiata 

 Pack. I have compared one of Mr. Grossbeck's specimens with 

 the type and, except that the central band is not quite so bright, 

 they are identical. It is a matter of individual opinion as to 

 whether amorata is worthy of being retained to designate an in- 

 termediate varietal form, or fall into the synonymy of californiata 

 Pack. I am inclined towards the latter view. 



The next variety of the summer form to be considered is 

 the melanic or black-banded form, which I previously described 

 as mephistaria Swett (Can. Ent., vol. XLVII, p. 157, May, 1915). 

 There are a few errors here that I must have made in copying 

 the dates, and should be corrected, as follows: — • 



Line 23, for Jan. 9 read July 9; line 24, for Feb. 3, read July 3. 



I doubt if any of thes2 forms are ever found at such early 

 dates as are thus erroneously given in this connection. 



This black-banded form is the same in size as the typical 

 form and is represented in both sexes, whereas I have seen the 

 bright, red-banded form, californiata Pack., only in the female, 

 though I see no reason why males should not be found. I believe 

 this range of coloration from reddish chocolate through light red 

 to black occurs in nearly all species of Xanthorhoe, e.g., ferru^ata 

 Clerc. and its black-banded var. unidentaria Haw.
