ORTIIOPTERA. 159 



named. Palisot de Beauvois seems to have selected the most 

 appropriate name for it; for the green portion of the wing- 

 covers is thick and opake, and the dusky portion thin and 

 semitransparent, as in the wing-covers of Hemipterous insects. 

 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 sur- 

 vive the winter, sheltered among the roots of grass and under 

 leaves. 



12. Lociista ( Tragocephala) radiata. Radiated locust. 



Rust-brown; thorax keeled above; wing-covers entirely 

 brown, but semiti'ansparent 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 

 first 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 tow^ards the end. The eyes are oval and 

 obhque, 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
