170 FAMILY V.-CEDIPODIN^. 



This beautiful insect is rather common in certain locali- 

 ties, like sandy shores of rivers and lakes. Its whole ap- 

 pearance shows it to be an inhabitant of white, or whitish 

 sand. Here it delights to bask throughout the warmer por- 

 tions of summer, and is especially numerous early in July. 

 Though very common it is not easily detected, nor captured, 

 as it is very vigilant, at least during the day. It is found 

 with Spharagemon collare and Dissosteira Carolina. 



GENUS Circotettix Scudder (1876). 



Eyes somewhat prominent ; vertex channeled and con- 

 tinuous with the median sulcus of the face ; head somewhat 

 broader than the anterior lobes of the pronotum ; posterior 

 lobe of the pronotum broader and acute angled behind; 

 median carina slightly elevated, with two rather deep 

 notches before the middle; lateral carina indistinct on the 

 posterior lobe, but not prominent. Wings and wing-covers 

 longer than the body ; the latter are of equal length through- 

 out, with the apex oblique; the former are rather broad.
