ORTHOPTERA. 103 



Sub-family II.— CEDIPODIN/E.* 



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

 prosternum is unarmed, the CEdipodincs, 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 fov< 



Encoptdlophus serdidus. 

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

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

 B. With a dark band across the wings. Spharagemon cequdle. 



A A. Wings with the disk black. Dissostiria Carolina. 



AAA. Wings with the disk red. Hippisais discoideus. 



The Clouded Locust, Encoptdlophus 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 . ^_ Encoptol 



color, mottled with spots of a 



darker shade. It appears somewhat like the variety infusedtaoi the 

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

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



* CEdipodinre, CEdipoda: oidos (oi'5o?), a swelling; pous (itOvZ), a foot.
