A remarkable paper, entitled, " Notes on some of the Genera [of 

 butterflies] of Mr. Scuckler's Systematic Revision," by Mr. T. L. 

 Mead, appears in the ' Canadian Naturalist.' These notes are 

 founded on a minute measurement of the lengths of various organs 

 which have been employed for generic characters, such as the 

 place of origin of the different branches of the veins of the wings, 

 the discoidal cell, length of antenna3, the joints of the palpi and 

 joints of the legs, &c., these measurements having been made 

 by means of a micrometer eye-piece to the thousandth of an 

 inch, the results proving that the venation of the wing is very 

 variable in specimens of the same species, and that no generic 

 distinction whatever can be based on slight differences in the pro- 

 portionate length of the cell and wing, or the origin of the first 

 and second branches of the subcostal nervures of the primaries. 



A catalogue of the 506 species of Diurnal Lepidoptera of 

 America north of Mexico is published by Mr. W. H. Edwards 

 in the Trans. American Entom. Soc, 1877. In this catalogue the 

 author rejects both the classificational and evolutional views of 

 Messrs. Bates, Scudder, &c., as well as many of the changes in 

 the nomenclature proposed by Mr. Scudder. His work, therefore, 

 *' adheres mainly to the order of Doubleday and his associates in 

 the ' Genera of Diurnal Lepidoptera.' " Rejecting, also, the special 

 classification ol the HesperidcB proposed by Mr. Scudder " which 

 was at once found olijectionable on account of the excessive 

 restriction of the groups called genera," he has given by way of 

 supplement a generic classification of them, written by Dr. Otto 

 Speyer, in which eleven genera only (in lieu of Mr. Scudder's 

 thirty-nine) are adopted. 



A notice of a small collection (fourteen species) of butterflies 

 from Cajje Breton Island is given by Mr. S. H. Scudder in the 

 Proceedings of the Boston Soc. of Nat. Hist. (vol. xviii.), 

 noticeable chiefly on account of the dimorphic and gynandro- 

 morphic character of the females of Eurymus Philodice, of thirty- 

 nine specimens of which ten were gynandiomorphic females and 

 eight pallid (dimorphic) females. 



A notice of a collection of thirty-three species of butterflies 

 collected in Colorado and Utah, by Dr. A. S. Packard (all of 

 which had been previously described), has been published by Mr. 

 S. H. Scudder in the ' Bulletin of the Geological and Geographical 

 Survey of the United Stales Territories ' (vol. ii.)
