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. 



Verify and investigate. Test the old and work out the unknown. 

 This is the keynote to applied entomological activity. The first is 

 hardly less important than the second. There is still too much tra- 

 dition current as truth, and some of these unproved, though accepted 

 statements, concern matters having a vital relation to control meas- 

 ures. It is a most hopeful sign of the times that so many real con- 

 tributions to entomological knowledge are appearing. They range 

 from popular bulletins based on recent studies of serious pests to 

 almost entirely original discussions of new forms of injury by obscure 

 species. We now have a series of publications which may well be 

 accepted as standards for similar work with other species or groups. 

 The end of such endeavor is by no means in sight. The studies of 

 recent years have resulted in the accumulation of man}- facts necessi- 

 tating a revision of our ideas respecting certain groups and opening 

 up many interesting and also most practical lines of investigation. 

 Some of these studies may not appear to have an immediate practical 

 importance, nevertheless progress along substantial lines depends in 

 large measure upon the continuance of just such apparently theoreti- 

 cal investigations, since a broad knowledge of biology in its various 

 bearings is an essential preliminary to the best practical work. 



It is unfortunate that the common name "locust" has been applied 

 to such widely divergent insects as grasshoppers and the periodical 

 cicada. The result is frequently amusing. Some months ago we 

 read an article in a popular magazine discussing the South African 

 grasshopper or locust situation. This notice was illustrated by a 

 series of excellent figures showing the periodical cicada. The latest 

 appears in a fruit paper in which one of our younger entomological 

 friends writes: "It is quite difficult to prevent the locusts or grass- 

 hoppers from depositing their eggs in the young shoots of fruit trees
