188 THE CANADIAN ENTOMOLOGIST. 



Our journal, the Canadian Entomologist, has been well sustained 

 during the past year, and through the kindness of our esteemed contribu- 

 tors we have been enabled to present our readers with many original 

 papers of great practical value. Mr. W. H. Edwards, of West Virginia, 

 has continued his very useful and valuable papers on the life histories of 

 our butterflies. Dr. Bailey, of Albany, N. Y., has given us an interesting 

 description of the various stages of Cossus Centerensis, illustrated by an 

 excellent lithographic plate. Many new species of insects have been 

 described by Messrs. A. R. Grote, W. H. Edwards, V. T. Chambers, Prof. 

 Fernald and others, besides which we have published a very large number 

 of papers of general interest. 



Among the more important recent contributions to our Entomological 

 literature may be mentioned a new edition of the Catalogue of the 

 Described Diptera of North America, by Baron Osten Sacken ; the Cole- 

 optera of Florida and Michigan, by John L. LeConte, M. D., and E. A. 

 Schwarz ; Peport on the Insect and other Animal Forms of Caledonia 

 Creek, New York, by J. A. Lintner ; the Coleoptera of the Alpine Regions 

 of the Rocky Mountains, by John L. LeConte, M. D. ; on the Collection 

 of Insects made by Dr. Elliot Coues in Dakota and Montana — the Or- 

 thoptera by Cyrus Thomas, Hemiptera by P. R. Uhler, Lepidoptera by 

 W. H. Edwards ; Notice of the Butterflies Collected by Dr. Edward 

 Palmer in Southern Utah and Northern Arizona, in 1877, by Samuel H. 

 Scudder; and an account of some insects of. unusual interest from the 

 Tertiary Rocks of Colorado and Wyoming, by the same distinguished 

 author. The elaborate and voluminous report of the U. S. Entomological 

 Commission on the Rocky Mountain Locust, with maps and illustrations, 

 issued in 1878, did not reach us in time to be noticed at our last annual 

 meeting. It is a work which has involved great labor, and besides con- 

 taining much that is new, covers the entire field of our knowledge in 

 reference to this destructive pest. Prof. C. V. Riley, of Washington, has 

 issued a special report on the Silk-worm, being a brief manual of instruc- 

 tions for the production of silk, with illustrations. Prof. A. R. Grote has 

 written Preliminary Studies on the North American Pyralidae, and Samuel 

 H. Scudder a Century of Orthoptera. Several additional numbers of 

 Edwards' magnificent work on North American Butterflies have appeared, 

 with charming plates. 



The members of the Entomological Commission of the United States 

 are devoting their attention this year especially to the Hessian Fly, inves-
