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

 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. Contributors are requested to supply electro- 

 types for the larger illustrations so far as possible. The receipt of all papers will be 

 acknowledged. — Eds. 



The campaign against the house fly is being vigorously pushed. 

 New fly traps have been devised in the last few months. In this issue 

 a new cockroach trap is described. These efforts are all praiseworthy, 

 though they are defective in that they fail to go to the root of the evil. 

 The entomologically sanitary premises and dwelling is a development 

 for the future. Progress is being made so far as the premises are 

 concerned, though little seems to have been attempted by architects 

 in designing dwellings which shall be moderately pest-proof. A study 

 of household pe^ts shows this is less difficult than the surgically clean 

 operating room of the hospital. It would seem as though a few moder- 

 ately expensive changes in the construction of our dwellings would 

 aid materially in eliminating the more obnoxious of our household 

 insects. 



The appearance of two volumes of the long expected monograph 

 on mosquitos by Dr. Howard and his associates, marks an important 

 epoch in American entomology. The work, noticed elsewhere in this 

 issue, embodies high scientific ideals, is a classic, and is cle.stined to 

 exercise a profound influence on the scientific investigations of the 

 future. Contributions of this general character are potent factors in 

 placing both economic and systematic entomology upon a thoroughly 

 sound, scientific basis. The writer has long been of the opinion that 

 substantial progress in our branch of science will be made largely by 

 investigations continued for a series of years in connection with, and 

 really an extension of the numerous supplemental studies which must 

 be made from season to season in solving immediate practical needs. 

 Every working entomologist should so plan his efforts as to have~ a 

 reasonable amount of time each year for purely scientific studies, 

 even though their practical bearings may be somewhat remote. 



The recently issued Proceedings of the British Columbia Entomo- 

 logical Society shows a most com_m.endable activity, and we take this 

 opportunity of extending the hand of good fellowship to the ento- 

 mologists of the Northwest. This society, organized in 1901, has been
