100 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
mixed with grayish; thorax dark brown; fore wings golden yellow above the fold, 
and dark cinereous, somewhat dusted with blackish beneath it. About the middle of 
the wing is an oblique silvery costal streak, black-margined on both sides, extending 
to the fold; another beyond the middle, meeting nearly in the center of the wing at 
an angle, a dorsal streak from the inner margin, the former black-margined on both 
sides, extending to the fold; another beyond the middle, meeting nearly in the center 
of the wing at an angle; a dorsal streak from the inner margin, the former black- 
margined on both sides, the latter internally; another costal streak near the tip with 
an internal circular black margin opposite to a dorsal streak of the same hue, and 
joined or nearly joined to it. Just behind the apical spot is a straight silvery streak, 
black-margined internally. A black round spot at the tip of the fore wings. Hind 
wings shining dark gray. (Clemens.) 
7. THE LOCUST SKIPPER BUTTERFLY. 
Eudamus tityrus Fabricius. 
Drawing the leaves together in July, a large pale green caterpillar about 2 inches 
long, with a red neck and large red head, with a large yellow spot on each side of the 
mouth, feeding by night, sometimes pupating between the leaves, and transforming 
into a stout-bodied, brown butterfly with a skipping, rapid, strong, low flight, and 
antennie flattened and bent over at the end. (Harris.) 
These voracious worms sometimes strip the leaves of the common 
locust and especially the viscid locust (Robinia viscosa), which is eulti- 
vated in New England as an ornamental tree. According to Harris, the 
females lay their eggs singly during June or early in July on the leaves, 
the caterpillars hatch in July, and when quite small conceal themselves 
under a fold of the edge of a leaf, which is bent over their bodies and 
secured by means of silken threads. When they become larger they 
attach two or more leaves together, so as to form a kind of cocoon or 
leafy case to shelter them from the weather, and to screen them from 
the prying eyes of birds. One end of the leafy case is left open, and 
from this the insect comes forth to feed. They transform to chrysalids 
either among the leaves or desert the tree and seek some retired place, 
where they spin a slight loose cocoon, within which they remain through 
the winter, appearing in the imago state by the middle of the following 
June. 
The butterfly is brown, the fore wings are brown with a transverse semi-transparent 
band across the middle, anda few spots towards the tip of a honey-yellow color; hind 
wings with a short rounded tail on the hind angles, and a broad silvery band across 
the middle of the under side. The wings expand from 2 to 2} inches. (Harris. ) 
Remedies.—Nearly all the insects which prey upon the foliage of the 
locust can be gotten rid of by hand-picking and by collecting the leaves 
in autumn and burning them; in this way cherished shade trees can be 
protected. 
8. THE LOCUST HISPA. 
Odontota scutellaris (Olivier). Hispa suturalis Harris. 
Order COLEOPTERA ; family CHRYSOMELID.®. 
In July, blister-like spots appearing upon the leaves, within which is a small flat- 
tened, whitish worm, with three pairs of feet; a quarter of an inch long, tapering
