either apically (female) or over the whole apical half (male), the veins 

 in the infuinated area blackish fuscous. Fore and middle femora 

 somewhat tumid in the male; hind femora ferruginous or ferrugiueo- 

 testaceous, obliquely bifasciate with blackish fuscous excepting below, 

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

 cated; hind tibiae bright red, the spines black excepting at base, eleven 

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

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

 scarcely and narrowly elevated margins, acutangulate apex, the median 

 sulcus confined 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 plate; cerci 

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

 rapidly beneath than above, beyond equal and about half as broad as 

 extreme base, apically rounded angulate, nowhere incurved, scarcely 

 so long as the supraanal plate; 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 longer than 

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

 which lies beyond the well rounded, scarcely elevated, entire, apical 

 margin. 



Length of body, male, 18.5 mm., female, 22.5 mm. ; antennae, male 

 and female, 8 mm.; tegmina, male, 16 mm., female, 20 mm.; hind 

 femora, male, 11.5 mm., female, 13.5 mm.

9. ABLDUS SERIES. 



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

 prozona is distinctly longitudinal. The interspace between the ineso- 

 sternal lobes in the same sex varies from subquadrate 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 

 fingers 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
