88 ENTOMOLOGICAL NEWS. [Feb., ' IJ 



known those entomological subjects on which students throughout 

 the country are engaged. We have therefore classified them under 

 one or more headings, the cross-references enabling the interested read- 

 er to learn of work done either from the taxonomic or the biological 

 side. Most of these papers will, doubtless, be published and, when 

 they appear, will be registered in our monthly summary of Entomologi- 

 cal Literature. As publication of many of them will probably not oc- 

 cur for some months, the present list is justifiable as giving advance 

 information to those who have not access to the programs on which 

 it is based. 



In this connection, however, we would call attention to the printed 

 abstracts of the papers presented to the American Society of Zoolo- 

 gists (97 pages), and the American Association of Anatomists (147 

 pages), published by the Wistar Institute of Anatomy and Biology, 

 Philadelphia, and sent before the meeting to the members of these 

 societies, and also the abstracts contained in the program of the Eco- 

 logical Society of America, also mailed before the meetings began. 

 These three give often fairly full summaries of the contents of papers, 

 although they include a relatively small proportion of the entomological 

 papers of the week. 



In the following list unmarked papers are from the program of 

 the American Association of Economic En.tomologists, those starred 

 (*) from that of the Entomological Society of America; others are 

 designated by the names, or abbreviations of the names, of the re- 

 spective societies to which they were offered. The total number here 

 listed is 139, of which 70 are from the program of the Economic En- 

 tomologists (including 6 from the section of Horticultural Inspectors 

 and 6 from that of Apiary Inspection), 26 from the Entomological 

 Society, 17 from the Zoologists, 14 from the Ecological Society, 5 from 

 Section F (Zoology), A. A. A. S., 3 from the American Society of 

 Naturalists, 2 from other sections A. A. A. S.. I from the Anatomists, 

 and I from the Physiological Society. The total is far in excess of 

 any previous one, the figures as reported in the NEWS for February 

 and March, 1916, pages 91, 143, being 85 (Cleveland, 1912), 74 (At- 

 lanta, 1913), 96 (Philadelphia, 1914), and 93 (Columbus, 1915).
