angustaius Uhl.) which although it belongs to a different subfamily 

 is frequently mistaken by farmers for the true chinch-bug. It dam-

 puncturing the leaves with its beak and causing them to wilt. 

 The life history of this bug should be worked up. We do not 

 know its eggs, the number of molts or the number of genera-

 Say, according to Heidemann, feeds on sycamore leaves and 

 passes the winter in the half-grown condition thrust down 

 in the crevices of the " button balls."

 They are laid in the spring and the young hatch soon afterwards. 

 The newly hatched bugs are pale yellow at first but grow red. 

 They molt four times before becoming adult and grow darker in 

 color and the adult is dark gray or nearly black. Over most
