138 THE CANADIAN ENTOMOLOGIST. 



Prof. Frey notices the dark anterior surfaces of the legs in this species 

 as remarkable, but the species is by no means singular in this respect. L. 

 tritaeniceella and other species are marked in the same way, and I did "not 

 consider it important to mention this character in the original specific 

 diagnosis of either species. Some specimens of salicifoHella are much 

 paler than others, and occasionally the dark margins of the fasciae are 

 very indistinct. Prof. Frey seems to have been misled by the mention of 

 L. pastorella by me in connection with this species. I wrote that this 

 species bore a strong general resemblance to L. populifoUella, as figured 

 (Nat. Hist. Tin.,) and as in that work pastorella and populifoliclla are 

 placed in the same group, I wrote that " it is not impossible that this is 

 L. pastorella" Pastorella and populifoliella are known to me only 

 through the Nat. Hist. Tin., and comparing the most densely dusted 

 specimens of salicifoliella with the figures in that work, I still think it 

 should be placed in the same group with those species. 



ON ORTHOSIA RALLA, Gr. & Rob. 



BY J. A. LINTNER, ALBANY, N. Y. 



In the April number of this journal, page 79, it is asserted by Mr. 

 Morrison that " the well known Orthosia ferruginoides Guen. is re- 

 described as Xanthia ralla Gr. & Rob." 



Having examined the type specimen of ralla, in the possession of the 

 Buffalo Society of Natural Sciences, I am able to pronounce it entirely 

 distinct, and further, that it differs so much from the species to which it 

 is above referred that there would seem to be no valid excuse for the 

 erroneous reference. 



In ralla the anterior wings are quite produced in their outer margin 

 at vein 3, and considerably excavated thence to the costa ; this marked 

 feature is not fully shown in the figure, in Trans. Am. Ent. Soc, i, pi vii. 

 The transverse lines are much more decided than in ferruginoides. The 

 anterior transverse line is less sinuous ; the post, trans, strongly lunulated 

 line is quite distinct. The conspicuous interspaceal black dots con- 

 stituting the subterminal line, might, by the the careless observer, be 

 mistaken for the black nervular dots or dashes of the lunules of the 

 preceding line in ferruginoides.. The orbicular has an interior black dot
