THE CANADIAN ENTOMOLOGIST. 71 



In a late number of the Transactions of the American Entomological 

 Society (vol. ii. pp. 67-88), Messrs. Grote and Kobinson give a long list of 

 errors that they have detected in our friend Mr. Walker's British Museum 

 Catalogues of Lepidoptera. It appears that, during a recent visit to Europe, 

 these gentlemen took the opportunity of examining the Museum collections, 

 and comparing the North American specimens with material that they had 

 brought vrith them for the purpose, and were thus enabled to identify many 

 of Mr. Walker's species, and decide upon the merits of others. From our 

 own experience of the insuflSciency of many of the descriptions in these 

 catalogues, and our having met with occasional errors in them, we feel com- 

 pelled to accept this list of emendations, especially as its authors are well 

 known as the chief and almost the only American authorities on this difficult 

 family of Moths. We do not, however, wish to be understood as subscribing 

 entirely to their strictures upon Mr. Walker's works, for we hold that a great 

 deal is due to him for the enormous mass of material that he has brought 

 together in them, and the immense amount of labour that he has bestowed 

 upon their compilation. And who indeed can wonder that some errors should 

 be detected in so vast a work, which perhaps no single individual should have 

 been called upon to undertake ? 



In order to render our notes as brief as possible, we give the following 

 names of species that are to be sfrucJc out of our Society's List No. 2, refer- 

 ring the reader to Messrs. Grote and Eobinson's paper for the reasons in most 

 cases : — 



Acront/cta longa, Guén. — This species was inserted in our list on the autho. 

 rity of the Brit. Mus. Cat. (ix. p. 60), which states that a supposed variety 

 of it was taken at Orillia, by Mr, Bush. This variety has since been described 

 as a distinct species by Mr. Grote (Pro. E. S. Phil. ii. p. 437, pi. 9, fig. 3), 

 under the name of A. Noctivaga. We took the insect at Cobourg, in June 1865. 



Mamestra ordinaria, Walk.; M. imicolor, Walk.; Apamea insignata, 

 Walk.; A. demissa, Walk.; Iliana undulifera, Walk.; GrapMpTiora ex- 

 pansa, Walk. ; Xanthia spurcata, Walk. ; Hadena contenta, Walk. ; Xylina 

 contraria, Walk. ; Anthaecia ri'vidosa, Guén., is the same as A. marginata, 

 (Haw.) Grote; Homoptera obliqua, Guén., a supposed variety of this species 

 taken by Mr. Bush at Orillia (C. B. M. xiii. 1054) is a rubbed specimen of 

 S. minerea, Guén. ; Homoptera calycantTiata, Smith (Bethune, Can. Jour. 

 1865, p. 251), according to Grote and Rob., is Zale Tiorrida, Hiibn. Not 

 having access to Abbot and Smith's work, our erroneous determination was 

 derived from Guénee's and Walker's brief descriptions, the latter of whom 

 had mistaken Z. horrida for H. Calycanthata. Hypena caecalis, Walk. ; 

 Ennychia glowteralis, Walk. 



Calpe Canadensis, Bethune. — ^This species is stated by Grote and Rob. to
