Entomologica Americana. — Commenced in 1885 by the amalga- 

 mation of two previously existing Journals, viz., the ' Bulletin of the 

 Brooklyn Entomological Society ' and ' Papilio.' It is published 

 monthly, and promises to be very useful. 



I have already said that the Annual Reports of Economic Ento- 

 mologists scarcely come within the purpose of my present notes. 

 But I may here allude to the Reports of the United States 

 Entomological Commission, the Annual Entomological Reports, 

 and the Bulletin, of the Department of Agriculture, in which the 

 names of Riley, Packard, Thomas, and Comstock figure con- 

 spicuously, and the Reports of the various State Entomologists, of 

 which those for Illinois, Missouri, and New York are especially 

 valuable ; there are others of which we know less in this country. 



CANADA. 



Canadian Entomologist. — A thin annual vol. of 12 monthly 

 parts, always containing useful information. Edited down to 

 vol. V. by the Rev. C. J. S. Bethune, and subsequently down to the 

 present time by our colleague Mr. W. Saunders, of London 

 (Ontario). The vol. for 1886 is the 18th. 



The Reports of the Entomological Society of Ontario, published 

 at Toronto "by order of the Legislative Assembly," are here men- 

 tioned, but they are outside vaj province, just as are several other 

 allied publications previously alluded to. The current annual vol. 

 is the 16th. They are analogues of the United States Official 

 Reports. 



I can scarcely hope the foregoing analysis, the outcome of an 

 idea originated scarcely more than a fortnight ago, is complete. 

 But I think it may prove useful. No doubt there are errors, 

 both of omission and commission : I shall be very glad of infor- 

 mation concerning them. 



Aids to Reference. 



In my Address last year I alluded to ihe fact that notwith- 

 standing the enormous increase of entomological literature latterly, 

 the facilities for reference had increased in proportion, in con- 

 sequence of the improved condition of our great Natural History 

 Libraries as compared with that of years gone by, and the 

 existence of " keys " or aids to reference. To go to a great library 

 for information on some special point without having a clue as to 

 where to find the reference, would be equivalent to seeking the 

 proverbial needle in the proverbial bottle of hay. No librarian
