92 JOURNAL OF ECONOMIC ENTOMOLOGY [Vol. 5 



forest entomologists and city entomologists concerned primarily with 

 shade tree pests, not to mention specialists working upon various 

 groups, or those with common interests because of climatic or geo- 

 graphical conditions. No one man can hope to cover the entire sub- 

 ject in an exhaustive manner, and most will probably find greater 

 profit by limiting the time spent at meetings to a few problems of 

 paramount interest. The Association might well have several gen- 

 eral sessions, possibly the entire mornings, the afternoons being broken 

 up into special groups which might be designated as sections and pre- 

 sided over by officers of affiliated societies, by vice-presidents or even 

 chairmen named informally. The main point is to assemble those 

 interested in any special subject and provide for a full and free dis- 

 cussion and at the same time avoid a conflict of interests so far as 

 practicable. Certain of these groups would necessarily vary from 

 year to year and would be determined in large measure by the char- 

 acter of the papers submitted. No party would be better qualified 

 to inaugurate this change than our Secretary, who could easily 

 group the papers and submit a proposition for a few special sessions 

 if conditions warranted, at the next annual gathering. We believe 

 that some such modification would do much to unite allied interests 

 and result in the continuance of one strong organization, with con- 

 genial sections or subdivisions. This is essential to a well supported 

 official organ and in the long run must prove more satisfactory than 

 a number of independent small organizations supported by entomolo- 

 gists restricting their activities to special lines.

Ixodidse. By L. G. Neumann, Das Tierreich, 26 Lieferung, pp. 

 XVI-169, 76 figs., R. Friedlander & Son, June, 1911. 



After a long delay, presumably chargeable to the publishers, Professor Neumann's 

 monograph of the ticks has been issued. The main criticism to be made is of the 

 fact that the work is not up-to-date; in fact, the publication is really about three 

 years behind, as 1908 is the last year given in the references to literature. Pro- 

 fessor Neumann is probably in no way responsible for this delay nor for the very 

 poor binding of the fascicle. 



Professor Neumann is generally considered a very conservative systematist, hence 

 the conservatism shown in this pubhcation is to be expected. The classification as 

 given in the present work is practically the same as that proposed by Neumann in 

 an earlier work. The author prefers to treat the ticks as a family rather than to 

 place them in a superfamily as done by Banks and several other authors. The 

 family is divided into two subfamilies Ixodina; and Spelseorhyncliina". The former 

 includes all of the forms u.suall}^ considered as ticks and the latter contains one genus
