A paper was read by George E. Burnham on the Catocalas, 

 with some account of the habits of these moths and personal 

 experiences in collecting them. 



E. J. Burnham exhibited egg masses of the White-marked 

 Tussock-moth (Notolophus leucostigma) and reported that they 

 were quite abundant on shade trees in the central portion of 

 the city. The attention of the Street and Park Commissioners 

 had been called to the matter, and a force of laborers was alread)- 

 engaged in collecting and burning the egg masses. The method 

 pursued was that adopted several years ago, when this moth 

 proved to be so costly a plague to Manchester. The laborers 

 are equipped with ladders and poles, each of the poles having 

 at one end an old-fashioned, three-tined steel table-fork, secure 

 y fastened and the tines bent at right angles to the handle.
