170 THE CANADIAN ENTOMOLOGIST. 



From the above references to special studies in several of the families 

 of the Lepidoptera, it will be seen that this attractive Order gives every 

 promise of soon occupying high vantage ground. 



In the other Orders — it is quite unnecessary that I should refer in the 

 Coleoptera to the labors of Drs. LeConte and Horn. You all know of 

 their untiring work, which has made the field which they are so thoroughly 

 working almost exclusively their own. 



In the Diptera, Mr. C. P. Whitney has published descriptions of a few 

 species of Tabanidae. 



Mr. W. H. Patton has communicated some descriptive papers on 

 Hymenoptera to the Canadian Entomologist. 



Mr. E. T. Cresson has published a catalogue of North American 

 Apidag, with descriptions of new species, comprising 108 pages of vol. vii. 

 of the Trans. Amer. Entomolog. Soc. 



Some valuable lists of species collected in particular regions have been 

 given us, which are of service in extending our knowledge of Geographical 

 Distribution. Among these, in the Coleoptera, may be mentioned, a list 

 by E. A. Schwarz of 1,457 Florida species (Proc. Amer. Philosoph. Soc, 

 v - *7j PP- 353-472) ; of 1,246 species from the Lake Superior region by 

 H. G. Hubbard and E. A. Schwarz ; by the same, of 1,787 species from 

 the lower peninsula of Michigan (loc. cit., v. 17, pp. 593-666) ; by Dr. 

 LeConte, of 220 species collected in the Rocky Mountains at an elevation 

 of 6,000 feet and upwards (Bull. Geolog.-Geograph. Surv. Terr., v. 4, pp. 

 447-480) ; additions to Messrs. Austin and LeConte's Catalogue of the 

 Coleoptera of Mt. Washington, of 89 species, extending the number to 

 319, by F. Gardiner, jr. (Psyche, v. 2, p. 211); 316 species from Wal- 

 lace Co., Kansas, by F. H. Snow (Trans. Kans. Acad. Sci., vol. vi., pp. 

 61-70); and additions of 435 species to the Catalogue of Kansas Cole- 

 optera, by E. A. Popenoe (ut. cit., pp. 77-86), increasing the number to 

 1,711. 



In the Lepidoptera, Mr. C. E. Worthington furnishes a list of 229 

 species of Noctuidas from the vicinity of Chicago, 111. (Canad. Entomol., 

 v. xi., p. 68) ; Mr. W. L. Devereaux, a shorter list of species taken in 

 Wayne Co., N. Y. (ut. cit., p. 105) ; Prof. F. H. Snow, a list of 104 species 

 collected in Colorado, by the Kansas University Scientific Expedition 

 in 1876. 



The valuable biological studies of Mr. W. H. Edwards have been
