THE RADIATED LOCUST. 
183 
sects. It is very common in pastures and mowing lands 
from the first of June to the middle of August, being found 
in various states of maturity throughout this period. The 
young also appear still earlier, and are readily known by 
their green color, and large compressed thorax, which is 
arched and crested or keeled above, and by their very short 
and flattened antennae. These locusts are sometimes very 
troublesome in gardens, living upon the leaves of vegetables 
and flowers, and attacking the buds and half-expanded petals. 
The larvae or young survive the winter, sheltered among the 
roots of grass and under leaves. 
12. Locusta (^Tragocephala) radiata. Radiated Locust. 
Rust-brown ; thorax keeled above ; wing-covers entirely 
brown, but semi-transparent at the end ; wings transparent, 
with brown network, and the principal longitudinal veins 
black ; they are very faintly tinted with green next to the 
body, have a large dusky cloud near the middle of the hind 
margin, and a brown streak on the front margin ; hind shanks 
reddish brown, a little paler below the knees, and the spines 
tipped with black. Length about 1 inch; exp. from 1| to 2 
inches. 
This species is now for the first time described. It seems 
to be rare. I captured one specimen in Cambridge on the 
1st of July, and have received another from Dr. D. S. C. H. 
Smith of Sutton, Massachusetts. It is found in North Caro¬ 
lina as early as the month of May in the perfect state. 
The following species have the face still more oblique than 
the foregoing, but the antennae are much longer, particularly 
in the males, in which they nearly equal the body in length, 
and are not enlarged towards the end. The eyes are oval 
and oblique, and there is a deep hollow before each of them 
for the reception of the first joint of the antennae. The 
thorax is not crested or keeled, but is flattened above, with 
three slender threadlike elevated lines, and the hind margin 
is very nearly transverse, or not much (if at all) angulated
