with narrower bands. As regards suppuraria I must entirely disagree 

 with them in placing it as a synonym of mephistaria Swett. They are 

 seasonal forms, are quite distinct both in size and width of median bands, 

 and I have never known them to intergrade. In my opinion suppuraria 

 bears the same relation to mephistaria that gigantaria bears to typical 

 defensaria. 



Hydriemena furcata var. periclata Swett. There is some doubt as 

 to the status of this specimen, either Mr. Swett has misidentihed it, or 

 the reference to furcata is incorrect. At the time I took the specimen in 

 question I recognized that it was different to any that I had taken pre- 

 viously. I read over carefully the published descriptions of this group, 

 and it seemed to me that it agreed very closely with periclata. At a 

 later date I sent it to Mr. Swett, who confirmed my identification, 

 remarking that "it is very nearly like type." Messrs. Barnes and 

 McDunnough in "A Review of the genus Hydriemena Hub." (Cont. 

 Lep. No. Amer., Vol. IV., No. 1), state that Mr. Swett has examined 

 the unique male type (of periclata) and informs them that unfortunately 

 the uncus is broken off but that the basal portion is rather narrow and 

 suggests that of furcata. Recently I have examined my specimen 

 under a binocular, and find that the uncus is of the shape which is 

 characteristic of the quinquefasciata group, and which materially differs 

 from the shape of the uncus in the furcata group. Until such times 

 as further nimotypical specimens of periclata can be obtained, the refer- 

 ence to furcata cannot be considered as entirely conclusive. For the 

 present I shall list it with a question mark as follows: H. furcata (?) 

 var. periclata Swett. 



Hydriemena californiata var. niveifascia Swett. Messrs. Barnes 

 and McDunnough have associated this form with irata Swett, instead of 

 californiata Pack., on account of the similarity of the male genitalia 

 which differs considerably in the two species named. This variety is 

 now known as H. irata form niveifascia Swett. 



Dysstroma muUeolata Hulst. It is rather doubtful if our large Van- 

 couver Island form is the true muUeolata. The type locality in Hulst's 

 description is given as Colorado, whilst the type specimen in the Hulst 

 collection at Rutger's College, N.J., is labelled "Washington," so it is 

 questionable whether this so-called "type" represents the true muUeolata 

 of Hulst. Again, Mr. Weiss who compared a specimen of the large Van- 

 couver Island form with this so-called "type" (which is in very poor 

 condition), may have misidentified it, as this large form, typical truncata 

 Huf., and citrata form punctum-notata Haw. are practically alike in 

 maculation. It is more than likely that the Hulst specimen, if the 

 locality label is correct, is really conspecific with the latter-named form. 



I wish to thank Mr. F. Kermode, our Honorary President and 

 Director of the Provincial Museum, for the loan of the cuts, from which 

 Plates 11. and III. were made to illustrate this paper. E. H. B.
