medial ineasuies suggested for tliis particular damage are to keep the 

 bog clear of other vegetation and as wet as consistent with good cul- 

 ture ; to keep the marginal ditch wide, clean, and at least partially 

 tilled with water, and to keep the dams clear of vegetation. 



The bulletin is an excellent illustration of the value of thorough, 

 scientific work in settling mooted questions and correcting common 

 error. We can see no good purpose, however, in encouraging the per- 

 petuation of popular error in this country by rejecting the term " locust" 

 for the short-horned locusts simply because the technical family name 

 Locustidic has come to refer to the long-horned species; while the 

 argument of popular use is without force when dealing with popular 

 error, and would oblige us to call ''turtles" " salamanders," and "go- 

 l)hers " " turtles" in some parts of the country, or perpetrate many other 

 ridiculous local usages, some of which are indicated in the item on 

 popular names for our commoner insects in this number of Insect Life. 

 The more recent classifications will also give Locustidii? priority for the 

 true or short-horned locusts (Smith's "grasshoppers"); include the 

 long-homed species or true grasshoppers in the Phasgauuridae and 

 the tree-inhabiting katydids in the Pseudophyllidie. 



New PubUcations of this Divisioti. -Bulletin Xo. 28, entitled "The More 

 Destructive Locusts of America north of Mexico," byLavrence Bruner, 

 was issued April 8, 1893. It consists of an illustrated account of 19 

 species of Acridiinai which have occurred in this country in such num- 

 bers as to attract particular notice, or which from their known habits 

 and relationships, are liable to become injurious. Each species is fully 

 described in all its stages, so far as these are known, and its range and 

 particular habits are given. The bulletin will enable the ready determi- 

 nation of the particular species in any future locust outbreak. 



Bulletin 29, also just published, gives the concluding facts in the 

 investigation of the Cotton Boll Worm {Heliothls armiger) which we 

 carried on during 1891 and 1892, mainly through our former assistant, 

 Mr. F. W. Mally, who is the author of the report. Few new facts are 

 brought out, but the bulletin gives the results of some accurate exper- 

 iments which will be of interest, and we trust of value, to cotton-grow- 

 ers in the regions where this destructive insect is particularly abundant. 



Changes of Address.— For the benefit of the correspondents of three of 

 our former assistants, Messrs. F. W. Mally, A. B.Cordley, and Nathan 

 Banks, we wish to state that none of these gentlemen are at present con- 

 nected with this Division. Mr. Mally's address is East Des Moines, 

 Iowa; Mr. Cordley's is Pinckney, Mich., and Mr. Banks's is Sea Cliff, 

 Long Island, iST. Y.
