ORTHOPTEROUS GROUP INSARAE 



very slight expansion cephalad at the cephalic margin, the point of least 

 width of dorsum consequently close to the cephalic margin; cephalic margin 

 of dorsum of pronotum gently arcuato-emarginate, caudal margin of same 

 very broadly arcuate with a very faint median emargination indicated; lat- 

 eral lobes of pronotum with length slightly less than the depth, the ventro- 

 cephalic angle obtuse and rounded, the margin from this angle to the humeral 

 sinus rather regularly arcuate, humeral sinus distinct and angulate but not 

 wide or deep. Tegmina rather long and broad, exceeding the caudal femora 

 in length, narrowing evenly from point of greatest width at the caudal margin 

 of the tympanum to the broadly rounded apex. Disto-dorsal segment of ab- 

 domen with median section showing a rounded, slightly depressed area; su- 

 pra-anal plate small, trigonal ; cerci very long and rather slender, slightly in- 

 curved, tapering from the base rather sharply for one-third the length, then 

 uniform to apex which is broadly and deeply flattened above and bowed out 

 below, the apex armed with a flattened tooth which is directed dorsad at a 

 right angle ;^' subgenital plate of moderate length, lateral margins sub- 

 parallel, somewhat elevated caudad and produced in slightly divergent, 

 slender, and non-articulate styliform processes, caudal margin broadly and 

 roundly emarginate. Cephalic and median limbs long and rather heavy 

 for the genus; cephalic femora much as in clegans, and, as in that species, 

 the genicular lobes bear a small supplementary spine; cephalic tibiae like- 

 wise similar. Caudal femora much as in elcgans but longer and slightly 

 heavier, with genicular lobes produced in longer and more uniformly slender 

 dentiform processes. 



The allotypic female, bearing the same data as the type, affords 

 us the data given below. 



Description of Allotype. — Similar to male in size and general appearance. 

 Tegmina equal to caudal femora in length. Ovipositor l6ss than cephalic 

 femur in length, bent sharply upward at base, the bent p'ortion of the dor- 

 sal margin and the distal extremity of the ventral margin finely serrate; 

 subgenital plate elongate, lateral margins compressed; the plate is sulcate 

 meso-proximad and does not embrace the base of the ovipositor. 



The single paratype, a female from Palmerlee, Arizona, is now 

 in the Hebard Collection. 



*^ In the original description both the figure and description of the cerci 

 are faultj'^ and misleading.
