78 THE CANADIAN ENTOMOLOGIST. 



Rev. Taylor says it is not a vaiiety of sordidata Fab. This is true in a 

 measure, as sordidata is only a variety itself. The suffused green colour 

 with white central bund will distinguish albifasciata from any variety. It 

 is closest to var. vulnerata of Swett, but in the latter the green is replaced 

 by red and has more bands on the fore wing, there being a marginal band 

 in vulnerata. Type, i 9 from Calif, in Pack. coll. This includes all 

 the varieties under /urcafa for the present, and the others lifted in Dyar's 

 Catalogue under sordidata Fab., such as glaucata^ bistriolata^ nubilofas- 

 ciata, are all good species and go into other groups, as I intend to show 

 later. Next after furcata and its colour varieties comes a very closely- 

 abied species, Hyd. rejiata Grote. 



2. Hydriomena reflata Grote, Can. Ent., XIV, i86, 1882. 

 Short palpi, grayish. 



This species has been a stumbling block for all of us, as the types in 

 the Brooklyn Institute of Sciences (Neumoegen coll.) were unknown for 

 some time to specialists. Rev. G. W. Taylor (Knt. News, July, 1907, 

 p. 310 and 311) says albifasciata Pack, is very close to this, which is true, 

 but the following differences can be distinguished, as 1 have just returned 

 from examining the types of both. The mesial band or second band from 

 body is very broad and black. Mr. Grote makes special mention of this, 

 and it is constant in all specimens I have seen so far, and the general 

 colour is gray, where the mesial band in albifasciata is very narrow and 

 the general colour is greenish with white mesial space. There is a cone- 

 shaped projection in the extridiscal band which is not found in albifasci- 

 ata. Dr. Barnes has a beautiful red variety o{ reflata from Arizona, male 

 and female, but the wide black mesial band is constant as in the types. 

 Specimens from Arizona and Victoria, B. C, both show this striking black 

 band and cone-shaped projection, which I do not find in albifasciata. I 

 place reflata Grote as a good species on account of these differences, and 

 because it has a red variety with the characteristic markings. The white 

 spot near the outer margin would tend to show that it is an allied form of 

 furcata^ so I place it to follow furcata. Mesoleuca abacta Hulst, 

 described in Can. Ent., Vol. XXX, p. 117, 1898, was said to be a 

 Hydriomena by Mr. Grossbeck in Trans. Am. Ent. Soc, XXXIII, Nov., 

 1907, and would probably be a synonym o{ reflata Grote. This is quite 

 true, as I have a photograph of the type sent me by Mr. Grossbeck 

 through Prof J. B. Smith's kindness, and it is the same as reflata., the 

 broad black mesial band showing plainly. The specimen in Brooklyn is
