The editors will thankfully receive news items and other matter likely to be of in- 

 terest to subscribers. Papers will be published, so far as possible, in the order of re- ' 

 ception. All extended contributions, at least, should be in the hands of the editor the 

 first of the month preceding publication. Reprints may be obtained at cost. Con- 

 tributors are requested to supply electrotypes for the larger illustrations so far as pos- 

 sible. The receipt of all papers will be acknowledged.— Eds. 



Attention is called to the announcement of the Entomologists' 

 Employment Bureau on another page. This disinterested effort on 

 the part of a few should be loyally supported by both employers and 

 employees. Any such means for bringing the two together can not 

 but react beneficially. 



A second installation of. the classified bibliography on insects and 

 disease appears in this issue. The subject is of vital importance to 

 the general welfare of the country, and such a compilation will greatly 

 assist entomologists keeping in touch with progress along this line. 

 Reference to the bibliograpny shows that there are still a number of 

 problems worthy of study in cooperation with the medical fraternity, 

 since without the assistance of the latter, material progress is impossi- 

 ble aside from general studies upon the biology and methods of con- 

 trolling pathogenic forms. 



A study of methods of illustration is not an unpromising subject. 

 One need only to look over entomological bulletins and reports, or 

 better still, recently published general works to see the great diversity 

 obtaining. Photographs of various degrees of excellence and an even 

 greater range of magnification appear here and there. The same is 

 true of line and wash drawings, and, to a certain extent, of colored 

 illustrations. These differences are greatly emphasized when inhar- 

 monious illustrations are assembled in some general work under 

 conditions precluding the preparation of a large series of original 

 figures. With many laboring under very diverse conditions, we must 

 expect great differences. Is it not possible, through a recognition of 

 certain fundamentals, to eliminate some of the more glaring incon- 

 sistencies? The degree of magnification has an important effect on 

 appearances. ' No illustration should be larger than necessary to 

 bring out important characters — mere size is not valuable in a figuie, 

 be it line, wash or colored. Nothing should be published unless some 

 valuable feature is clearly shown. An illustration unintelligible
