The Chickweed Geometer, Hamatopis grataria (Hae- 
mat'o-pis gra-ta'ri-a).—This little moth 
(Fig. 342) is very common in our meadows 
and gardens during the summer and au¬ 
tumn months. Its wings are reddish 
yellow, with the fringes and two trans¬ 
verse bands pink. It is found from Maine 
to Texas. The larva feeds on the common chick-weed,

Family GEOMETRID^E (Ge-o-met'ri-dse). 
The Green Geometrids (Ge-om'e-trids). 
As a rule the members of this family are bright green in 
color. And as we have 
but one other common 
Geometrid ( Dyspteris , p. 
286) of this color, the 
family may be well termed 
the Green Geometrids. 
vn, The distinctive structure 
that characterizes this 
family is the fact that 
vein V a of the hind wings 
arises much nearer to 
vein V, than to vein V 3 
(Fig. 343). In this family 
the tendency to expan¬ 
sion of the humeral angle 
of the hind wings, which 
is exhibited by all Geo- 
metrina, and which is cor¬ 
related with the promi¬ 
nent bend into this angle 
of vein II, characteristic 
of this super-family, is

most common species, and not as a typical illustration of the Sterrhidae. It
