The male moth is dark brownish gray and mottled ; the female is 

 dirty white with irregular dark markings. The female, though pro- 

 vided with wings, is unable to fly. 



At any time during the fall and winter months the egg masses may 

 be destroyed by soaking them with creosote oil. A good formula 

 for this purpose is : 



Creosote oil, 50^ 



Carbolic acid, 20'^f 



Spirits turpentine, 2o^c 



Coal tar, 10^ 



A sufficient amount of this should be applied to each egg mass to 

 insure reaching every egg in it. 



The habit the caterpillars have of feeding by night and lying hid- 

 den during the day is made use of by putting loose bands of burlap 

 around the trunks of the trees for the caterpillars to hide beneath, 

 these bands being examined every day or two and the caterpillars 

 there being destroyed. Banding in this way should be begun by the 

 first of May. Trees not infested and not touching others can be 

 protected by bands of Tree Tanglefoot around their trunks. Spray- 

 ing infested trees heavily with arsenate of lead is also a valuable 

 treatment and the clearing out of underbrush is necessary in infested 

 districts. Fuller descriptions and information can be obtained by 

 applying to the Gypsy Moth Commission, 6 Beacon St., Boston, 

 which has excellent illustrated bulletins about this insect for dis- 

 tribution. 



THE BROWN-TAIL MOTH. 



{Euproctis c/irysorr/ui'a L.) 



This insect, which is a well-known European pest, was brought to 

 ^Massachusetts about 1892, and is now found throughout the eastern 

 half of the state, and also in New Hampshire, Maine and the Mari- 

 time Provinces, and is likely to be found in northern Rhode Island 

 and northeastern Connecticut, though it has not thus far been re- 

 ported from there. The adult moths appear early in July and fly 

 for perhaps two weeks. They are pure white except for a golden 

 brown tuft at the end of the body of the female, which has given the 

 insect its name. They spread from an inch to an inch and a half
