ORTHOPTERA, 



Sub-family II. 



The second of the two more important sub-families in which the 

 prosternum is unarmed, the (Edipodince, includes genera in which 

 the head is rounded at the union of the vertex and front ; and in 

 which the front is perpendicular or nearly so. The antennae are 

 linear or sub-linear, and usually inserted nearer the mouth than the 

 middle of the eyes ; sometimes they are inserted just in front of the 

 eyes. The eyes are small or of medium size ; rarely longer than 

 that part of the cheeks below the eyes. . The posterior lobe of the 

 pronotum is longer than the anterior part in the typical forms ; and 

 the median carina is frequently entirely or partially crested. As 

 with the preceding sub-family, the last spine of the outer row of 

 the posterior tibiae is wanting. 



We have many representatives of the CEdipodinae, and these are 

 distributed by modern systematists among numerous genera. I 

 have selected a few of the more common species of the Eastern 

 United States as illustrations. These can be separated by the fol- 

 lowing table : 



A. Wings with the disk yellow. 

 B. Apical half of wing dusky. 



C. Dorsal aspect of head with a slight median carina, which is quite prom- 

 inent in the well-marked depression on the vertex (central foveola). 



Encoptolophus sordidus. 



CC. Dorsal aspect of head without median carina, or with merely an indi- 

 cation of one; central foveola less distinct. Chortophaga viridifascidta. 

 B. With a dark band across the wings. Sphardgemon aqudle. 



AA. Wings with the disk black. Dtssosterta Carolina. 



AAA. Wings with the disk red. Hippiscus dtscoideus. 



The Clouded Locust, Encoptolophus sordidus. This species is 

 very common in the Eastern Uni- 

 ted States during the autumn. It 

 abounds in meadows and pastures ; 

 and attracts attention by the 

 crackling sound made by the males 

 during flight. It is of a dirty-brown FlG ^,- E ncottoiophu S sordid. 



color, mottled with spots of a 



darker shade. It appears somewhat like the variety infuscdta of the 

 following species, but it can be easily distinguished by the charac- 

 ters given in the table above. Size same as following species.
