yet to be discovered. Something can be done by burning in au- 

 tumn all rubbish about fields, in fence-corners, and in other pL 

 where the bugs have congregated to pass the winter. The march- 

 ing of the spring brood into new fields has been stopped by means 

 of ditches, as is done with the Army-worm. Some farmers have ac- 

 complished the same purpose by making a line of gas-tar on the 

 ground ; the bugs will not pass such a line, but it is necessary to re- 

 place it frequently. In some cases kerosene emulsion can be used 

 to advantage. 



Family XXXI. BERYTID^E.* 



The Bcrytidic consists of a small number of species, which on 

 account of their attenuated forms are very striking in app 

 ance. The body is long and narrow; the legs and antennae are also 

 tremely slender. There is a transverse incision in the 

 vertex in front of the ocelli. The antennae are four-jointed, elbowed 

 at the base of the second segment, and with the tip of the t 

 ment enlarged. The rostrum is four-jointed ; and the memb; 

 of the wing-covers is furnished with a very few veins. 

 Only two genera are catalogued from 

 United States, each represented by a 

 lc species, Ja/ysns spitwsus and A
