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. 



This issue reflects the increased importance of shade tree insects, 

 pests which, in connection -with untoward climatic and other conditions, 

 have brought about an acute situation in the northeastern United 

 States, at least. It is the logical outcome of extensive plantings of 

 one or two varieties through a long series of years. The first essential 

 is to afford speedy relief by the general adoption of methods for check- 

 ing insect depredations. This should also be accompanied by a recog- 

 nition of the underlying causes, with a view of adjusting conditions 

 in the future in such a way as to minimize the danger of extended 

 injuries. The horticulturist and landscape gardener should advocate 

 more diversified plantings and endeavor in the near future to correct, 

 so far as practical, the illogical settings of earlier years. Maples and 

 elms, while admirable shade trees in many respects, are by no means 

 the only species which can be planted to advantage upon streets and 

 in parks. 



Most economic entomologists will concede that the Bibliography of 

 the More Itnportant Contributions to American Economic Entomology 

 is an exceedingly useful compilation, since it includes in eight small 

 parts the writings of all American economic entomologists up to Jan- 

 uary 1, 1905. We have been expecting for some time another issue 

 bringing the bibliography down to 1910 and were surprised to receive, 

 in response to an inciuiry, the statement: "By decision of the Secretary 

 of Agriculture" such work would in the future be limited to the Experi- 

 ment Station Record. This latter publication is of great service to 

 the economic entomologist and is frequently consulted. Nevertheless, 

 we favor the publication of the bibliography of economic entomology 

 and trust that the Federal Authorities will continue the issuance of 

 this extremely serviceal)le and convenient work, a compilation of 

 greatly increasing value with the advance of years. A readily avail- 

 able literature is an important factor in research work of all kinds.
