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 antenna. 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 Iarva3 or young survive the winter, sheltered among the 

 roots of grass and under leaves. 



1 2. Locusta ( Tragocephald) 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 If 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 antennas. 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
