68 THE CANADIAN ENTOMOLOGIST 



like figure 40 from Victoria, B.C., which is ethela Hulst. Figure 

 41 of the same plate is our eastern hersiliata, while figure 42 is 

 Dysstroma {Mesoleiica) occidentata, described by Taylor in the 

 Canadian Entomologist, vol. XLII, p. 86, 1910. Note the sharp 

 indentation of t^e intradiscal line in the figure, on the median 

 vein, also the peculiar central band and wide basal space. There 

 is always a chance of error in determining species from figures, 

 but as Packard had the specimens in his collection, from which the 

 figures were made, I think I have identified them correctly. 



Dr. Dyar (Proc. U. S. Nat. Mus., vol. XXVII, p. 897, 1904) 

 describes the larvae of hersiliata Guenee and mentions rearing them 

 on currant. Dr. Dyar also mentions that there is considerable 

 variation in this species, there being a dark and a light form, and 

 he thought the latter might be ethela of Hulst. Both forms will 

 have to be studied as they seem to differ from our eastern hersiliata. 

 Possibly they may be forms of occidentata Taylor. 



Traversata Kellicott (Bull. Buffalo Soc, Vol. V, p. 45, 1886 

 [transversata in error in Dyar's ListI) is not to be considered 

 under citrata (truncata) as it belongs to another group. 



Atrifasciata Hulst. (Entomologica Americana, \'ol. HI, p. 

 214, 1887) described from one female from California, turns out 

 to be a Eustroma or Lygris and not Cleora or Mesoleuca as placed 

 by Hulst. (See Grossbeck's notes in Trans. Amer. Ent. Soc, 

 vol. XXXIII, p. 338, November, 1907.) 



Mesoleuca mulleolata Hulst is placed incorrectly as a synonym 

 of truncata in Dyar's List. It was described in the Bulletin of the 

 Brooklyn Entomological Society, vol. IV, p. 26, 1881, and is a very 

 large species and very distinct when once separated. There were 

 two types from Colorado in the Hulst collection, and I shall restrict 

 the type to the white banded form there. This, in a general way, 

 resembles the aberration punctum-notata Haworth cf citrata, but 

 the basal band of the fore wings has two very strong, toothed 

 projections and the intradiscal band is inwardly less crenulate 

 than in citrata. The extradiscal line of the fore wings runs straight 

 from costa about 2.5 mm. before the first projecting tooth, and also 

 the costal reddish spot is more accentuated than in citrata. The 

 hind wings of mulleolata Hulst are darker than those of citrata, 

 and the extradiscal line makes a much sharper angle. Then
