Paratettix cucullatus Burm. 



This species (Fig. 65) is easily recognized 

 by the form of the vertex. From above 

 this appears about equal in width to one 

 of the large and prominent e^-es, and does 

 not project in advance of them ; its front 

 margin is slightly hollowed, the concavity 

 being divided by the mid-carina which pro- 

 jects a little. In profile the frontal costa 

 is slightly sinuate opposite the eyes and 

 strongly protuberant opposite the anten- 

 nae. The crown of the head is channeled 

 longitudinally^ on either side of the mid- 

 carina, the sulci being stopped abruptly opposite the hinder 

 portion of the e\'es b\" a pair of transverse, sometimes slight- 

 ly oblique, ridges. This character is found in several species 

 of this genus and in this species appears at a very early 

 stage, showing distinctly in specimens only 3 mm. in length. 

 The body is less compressed than in granulatus, being, in 

 truth, depressed rather than compressed. The pronotum is 

 advanced upon the head to the eyes, and the median carina 

 is obsolete on the anterior portion; the posterior process 

 extends 2 to 3 mm. beyond the hind femora, exceeded by the 

 wings, and is very constant in proportions. 



Measurements — Length of bod}', 10 mm.; pronotum, 12 

 mm.; posterior femora, 6 mm. 



This species is very abundant in low fields fairly free 

 from vegetation. It deposits eggs, like most of the locusts, 

 in pod-like masses in the earth; 25 to 32 eggs have been 

 found in each pod. The eggs hatch in about sixteen days 

 into pale yellowish-white insects, with large and swollen 

 heads, red eyes and short antennae.
