sides and middle line of the head, disk of the prothorax, scutel- 
lum, most of the breast, dots along the sides of the abdomen, its 
tip, and two spots on each side of the middle of the venter, black. 
A broad, black, transverse band is found across the middle of 
the wing-covers, and the membrane is also of the same color. 
It is a very showy insect, but is of no economic importance as 
it is only found upon the plants already named. ‘The insect is 
illustrated in Fig. 60. 
Lygeus turcicus Fab., illustrated in Fig. 61, is also very 
common in our state, as is the similar L. reclivatus Say. The 
former species, smaller than the milkweed bug, has a_ bluish- 
black triangular area surrounding the scutellum, and a large

In the sub-family Myodochina occur a number of species 
which are frequently mistaken for the true chinch-bugs. Some 
of them occur in such vast numbers late in autumn as to cover 
whole fields, thus alarming the farmers. This is especially true

Fig. 62, and the Emblethis arenarius Linn. (Fig. 63), which
