NEW TREATMENT FOR THE WOOLY APHIS. Simply use Christian 

 Science. There is no such insect ; it is an invention of mortal mind. 

 This is readily demonstrated by consulting Webster's or the Century. 

 The proper spelling is woolly, and there is no word wooly, hence no 

 wooly aphis, and no need of bulletins on the subject. Missouri and 

 Georgia entomologists, and all agricultural editors, please take notice.

RESEARCHES ON NORTH AMERICAN ACRIDIID.E. By Albert Pitts Morse. 

 Publication No. icS, Carnegie Institution of Washington. 53 pp., 

 8 pis., 13 text figures. 



In the presentation of this paper to the entomological world Prof. 

 Morse has given us one of the most interesting and important papers pub- 

 lished in recent years on American Orthoptera. The subject matter has 

 been gleaned from a large series of specimens collected in the south- 

 eastern states by the author on a trip made in the summer of 1903, under 

 the auspices of the Carnegie Institution. The territory covered extended 

 from Norfolk, Virginia, to the vicinity of Pensacola, Florida, special 

 attention being paid to the mountainous region of western North Carolina. 



The paper is divided into a number of sections, the most interesting 

 and important of which are "Zonal Distribution, Locust Societies and 

 Habitats, a Comparison of Campestral and Sylvan Locusts, Macropter- 

 ous and Brachypterous Species of Locusts, Brachypterism in other Or- 

 thoptera," and finally an annotated list of species and localities for each. 



Under " Zonal Distribution" (p. 13) by a rather peculiar lapse Eritet- 

 tix is omitted from a list of genera of austral origin not restricted to the 

 eastern states, and Scirtetica is said to be confined to the east while the 

 reverse is true. The section on locust societies is worthy of special note 

 as it furnishes a basis for future work in this intensely interesting field. 

 The table of societies presented on page 14, while preliminary and ten- 

 tative, is evidently the product of considerable study, and, while a con- 

 sideration of these divisions is unnecessary, it may be remarked that to 

 the few hygrophilous phytophiles given there should be added Linoce- 

 p/ia/us e/egans, which species is typically halophilous in New Jersey. 



After a discussion of the relation of brachypterous and macropterous 

 species to their habitats, the author sums up his evidence in the statement 

 that : " Brachypterism in locusts is a more complete adaptation to a K ap- 

 ing mode of progression brought about by life in situations where flight 

 is difficult or impracticable, and consequently disadvantageous." While 

 this appears to be more plausible than any theory hitherto advanced on 

 the subject, it has numerous exceptions, one of the most striking of 

 which Prof. Morse's limited stay in the south did not permit him to 

 observe, namely the great abundance of the macropterous Ainblytro- 

 occidentalis in typical sylvan surroundings.
