INTRODUCTION. 



The present bulletin is the third of the new series of this Division to 

 contain miscellaneous short articles and notes. It presents a number 

 of articles of more than usual interest. The record of experiments on 

 drying fruit affected by the San Jose scale is of international impor- 

 tance in view of the recent legislation by foreign countries barring 

 American dried fruits from entrance. The account of the work against 

 the fluted scale, Icerya purchasi, in Portugal contains another striking- 

 example of the value of the study of natural enemies of injurious insects. 

 The articles by Mr. Chittenden on twig pruners and a new borer enemy 

 of the birch are of interest on account of the recent damage by these 

 destructive insects and of importance since they bring to notice some 

 species new to this form of damage. The peach Lecani um article by Mr. 

 Pergande will, it is hoped, settle the long- mooted question as to the 

 identity of the brown scale which so frequently damages peach trees, 

 and that upon a new Coccid on birch describes with great care the life 

 history of a remarkable insect which has ruined the bark of the beauti- 

 ful white birch over a large extent of the Lake Superior region. The 

 periodical Cicada articles by Mr. Marlatt are also of special interest, 

 the first one proposing for the first time a rational nomenclature for 



the different broods of this unique insect.
