 subject. This table shows that the percentages ol titles dexoted to classihca- 

 tion in the different journals ranged from 41.1 to S;^9. In nearly all of the 

 journals more than 50 per cent, of the papers were on this subject. The per- 

 centages of titles on distribution, etc., \aricd from 3.2 to 17, those on anatomy 

 etc., from I to 22 per cent., and those on life-history, etc., from S to, 20.7 per 

 cent. The remaining percentages in this table are low, except h)r the economic 

 and general subjects. 



TABLE III, PERCENTAGES OF MAJOR PATERS DEVOTED TO EACH SUBJECT. 



Fifteen groups or orders of insects were treated in the major papers of all 

 journals as shown in Table I\', with the Coleoptera leading and followed by 

 the Diptera, Lepidoptera, Homoptera, Hymenoptera, Hemiptera and Odonata. 

 The main orders of insects were covered in each journal. No one group was 

 represented to the exclusion of others, however several journals showed a con- 

 siderable leaning toward some particular order, probabK- due to the fact that 

 most of the contributing authors to those journals were interested in such a 

 group. 



Table \ is of interest in showing the locations of authors of major i)apers. 

 The District of Columbia leads with a total of 63 papers in all of the magazines 

 listed. This is due undoubtedly to the large number of federal entomologists 

 located there. Massachusetts, New York, Illinois, New Jersey, California, 

 Pennsylvania, Canada and Ohio follow the District of Columbia in the order 

 named, in so far as the number of titles is concerned. Several of the journals 

 receive papers from many states, while a few appear to be devoted mainly to 

 contributions from one or two states, at least such was the case during 1919. 



It is no secret that most of our entomological publications or journals have 

 seriously felt the increased cost of living during thp past several years ,and
