THE CANADIAN ENTOMOLOGIST. 1 67 



scattered through the various scientific and popular journals, government 

 surveys, and other publications. Two numbers of the scries have been 

 issued — the first containing a complete list to date, it is believed, of the 

 Entomological writings of Dr. John L. LeConte, and the second, those 

 of Dr. George H. Horn. A third, of the writings of Mr. S. H. Scudder, 

 is nearly completed. I regret that it has been thought necessary, in this 

 series, to dispense wholly with the use of capitals in all scientific names, 

 even in the family and ordinal divisions, and I believe that many of you 

 will agree with me in claiming for the royalty of science exemption from 

 conformity to an innovation based on mere convenience. 



Prof. C. V. Riley and J. Monell have contributed to the Bulletin of the 

 U. S. Geolog.-Geograph. Survey (vol. v., pp. 1-32) a paper entitled 

 Notes of the Aphididce of the United States, with Descriptions of Species 

 Occurring West of the Mississippi. Part I contains extended biological 

 notes on the Pemphiginee, by Prof. Riley, and Part II, notes on Aphidinae 

 with descriptions of new species, by Mr. Monell. The paper, illustrated 

 by two plates, is a valuable contribution to our knowledge of these 

 exceedingly interesting insects. 



A special Report from the Department of Agriculture, entitled, The 

 Silkworm, being a brief Manual of Inst ruction for the Production of Silk, 

 has been prepared by Prof. Riley, and largely distributed by the Depart- 

 ment, to meet the demand from various portions of the United States for 

 information upon the important industry of silk-culture. The Manual is 

 quite full in the natural history of the Silkworm, in the methods of cul- 

 ture, and directions for reeling the cocoons. There seems no reason why 

 this industry, properly fostered, may not be made to add materially to the 

 productive resources of our country. 



Abstracts of the papers presented by Prof. Riley at the St. Louis 

 meeting of the American Association for the' Advancement of Science, 

 have been published in the Proceedings of the Society, and also in a 

 separate pamphlet. Among these are Notes on the Life-history of the 

 Blister-beetles and on the Structure and Development of Hornia : On the 

 Larval Characteristics of Corydalus and Chau/iodes. and A New Source of 

 Wealth to the United States [Sericulture]. 



A Century of Orthoptera, commenced by Mr. S. H. Scudder in 1868, 

 and continued at intervals in vols. 12-20 of Proc. Bost. Soc. Nat. Hist., 

 has been completed during the present year by the publication of the last 

 three decades, in vol. 20, op. cit.. The species described pertain to the
