 the under face lighter or deeper orange, the whole geniculation infus-

 to thirteen in the outer series. Kxtremity of male abdomen a little 

 clavate, slightly recurved, the supraanal plate triangular with straight, 

 scarcely and narrowly elevated margins, acutangulate apex, the nuMlian 

 sulcus con lined to the basal half, tapering, narrow, and very deep, 

 between high and sharp walls, which unite in the middle of the plate; 

 furcula consisting of a pair of slight, brief, parallel, moderately distant 

 spines lying upon the bases of the ridges of the supraanal i)late; cerei 

 small compressed laminae, tapering rapidly in the basal half and more 

 rapidly beneath than abovv, beyond equal ami about half as broad as 

 extreme base, apicaPy rounded angulate, nowhere incurved, scarcely 

 so long as the supraanal [date; infracercal plates very broad at base, 

 extending far outside the cerci, rapidly narrowing with straight mar- 

 gins, distinctly shorter than the supraanal plate; subgenital plate 

 small, subequal or broader apically than basally, hardly h>nger than 

 broad, bluntly subconical, terminating in a very blunt, heavy tubercle* 

 which lies beyond *Ue well louuded, scarcely elevated, entire, apical 

 margin.

l». ARIDUS SERIES. 



In this group the antennae of the male are exceptionally long and the 

 pro/ona is distinctly longitudinal. The interspace between the meso- 

 sternal lobes in the same sex varies from subfjuadrate to half as long 

 again as broad, while in the female it varies from distinctly transverse 

 to much longer than broad. The pronotum is posteriorly truncate or 

 subtruncate, usually broadly emarginate. The tegmina are not only 

 abbreviate but rarely as long as the pronotum, lateral and distant. 

 The hind femora are long, and the hind tibiae light colored, with eight 

 to twelve, generally about ten, spines in the'outer series. 



The supraanal plate of the male is triangular and rather simple; the 

 last dorsal segment is obliquely and deeply sulcate on either side of the 

 base of the furcula, which consists of a pair of very slender parallel 

 tiugers or spines of variable length, but never very long; the cerci 

 rapidly narrow at the base to a long and exceedingly slender incurved 

 blade, hardly as long as the supraanal plate, and narrower by far than
