EUROTETTIX, new genus. 



As indicted b}' the synopsis of the Melanopline genera of Paragua}'^, 

 this genus is composed of brachypterous insects, the chief color of 

 which is ferruginous. Related to Chloru^ Giglio-Tos. Body and legs 

 moderately hirsute. 



Head large and broad, about as wide as the front edge of the pro- 

 notum; eyes large and prominent, nearl}" twice as long as the cheeks 

 below them; vertex but little broader than the width of the basal 

 antennal joint, the fastigium depressed and spatulatel}' deeply sulcate; 

 frontal costa fading before the clypeus. Antennte filiform, a little 

 longer than the head and pronotum together. Pronotum with the 

 anterior lobe cylindrical, the hind lobe considerably expanding, much 

 shorter than the anterior; the transverse sulci quite distinct, front 

 edge subtruncate, hind edge subangulate or broadly rounded. Teg- 

 mina greatly abbreviate, broadly ovate, their inner edges not quite 

 touching. Hind femora large and robust, considerably surpassing the 

 apex of the abdomen. Anterior and middle femora robust. The latter 

 a ver}" little enlarged apically, the last ventral segment short, entire at 

 apex; supraanal plate scutellate, the cerci long, slender, pointed, and 

 decurved at apex. Interspace between the mesosternal lobe nearly or 

 quite as broad as long, but narrower than the lobes themselves. Pro- 

 sternal spine broad at base, short, acuminate.

 be separated as follows:
