As to the methods of fighting the insects, nothing need be said here 

 at present. 



Note.- — On the matter of climatic conditions, Mr. E. W. McGann, of the 

 New Jersey State Weather Service, furnishes the following data : The mean 

 August temperature for Boston is 68.5° ; the mean temperature in 1895, when 

 a partial second brood appeared, was 71°, or 2.5° above the normal. Early 

 September also showed unusually high temperatures, but they did not continue. 

 In New Jersey only the extreme northern stations report normals as low as 

 that of Boston, while most of them, even north of the red shale line, report 

 normals exceeding the exceptional Boston record of 1895. Those given by Mr. 

 McGann are : Dover, Morris county, 71.9° ; Deckertown, Sussex county. 

 71.2° ; Boonton, Morris county, 73.2° ; New Brunswick, Middlesex county, 

 72.6° ; River Vale, Bergen county, 71.4°. 



This would indicate that even in northern New Jersey there would 

 be a tendency for the hatching of the summer eggs and a correspond- 

 ing natural check to gypsy moth increase. 



THE BRO'WN-TAIL MOTH. 



Eiiproctis chrysorrlKxa Linn. 



This is the other of the species that has been introduced into Massa- 

 chusetts within recent years, scarcely second to the gypsy moth in 

 destructiveness, while more annoying than that insect because of the 

 fact that the hair or vestiture covering the caterpillar is more or less 

 poisonous in the later stages. According to the reports of Dr. C. H. 

 Fernald, from whose writings much of the information here given is 

 obtained, the insect was first reported in this country in Soinerville, 

 Mass., in the spring of 1897, and careful inquiries revealed 

 the fact that it had been observed by some of the residents of that 

 locality for at least five years. In the center of the infested region 

 is a florist establishment, where, previous to 1890, roses and other 

 shrubs were imported from France and Holland, and it seemed very 

 probable, from all the facts obtained, that the brown-tail moth was 

 accidentally introduced on some of these plants as early as 1885. 



Mr. A. H. Kirkland, writing several years afterward, puts the 

 matter in a somewhat different shape. In a paper before the Asso- 

 ciation of Economic Entomologists, in June, 1900, he makes it: 

 ^'Area infested in the fall of 1896, twenty-nine square miles; 

 fall of 1897, 158 square miles; fall of 1898, 448 square miles; 

 fall of 1899, 928 square miles. In the course of my visits to
