space, 16/20 (60 units = 1 mm). Head length, 26. Rostrum reaching mid¬ 
way between anterior and middle coxae. 
Pronotum length, 103; width across humeral angles, 97; slightly carinate 
on mid-line; coarsely pitted caudad of silvery patches, pits deep on margins 
and transverse row behind silvery patches, shallow on disc. 
Abdomen long (166 caudad of posterior median angle of pronotum); width 
67 at middle. Connexival spines short, barely produced. Seventh sternum 
tumid posteromedially, tumescence abruptly truncate and excavate poste¬ 
riorly; sterna II and III distinctly carinate on median longitudinal line; pleura 
II-IV of male, II and III of female each with a median vertical furrow on 
both sides, and sometimes a small depressed spot on tergite V of male and 
IV of female. Genital segments long (47), set with long hairs. Male paramere 
as shown in Figure 6. 
Antenna moderately long, stout, clothed with short recumbent pubes¬ 
cence, and longer setae ventrally on segments II—III; segment IV with scat¬ 
tered long setae; segment I curved, segment IV subfusiform; proportions I- 
IV, 57:44:37:32. Fore tibia with distal comb, also an adjacent black pad 
ventrally; middle tibia with distal comb; posterior tibia with blunt apical 
spur. Femora and middle tibia with rather evenly spaced long setae ven¬ 
trally, 10-14 per leg segment; tibia thickly set dorsally with long semi-re- 
cumbent setae, hind femora and tibia clothed with such setae. Legs unarmed 
except posterior femur armed beneath with about 8 small black spines before 
middle, one larger black spine beyond middle (at 0.6 toward distal end) 
followed by 9 or 10 small spines decreasing in size distally; anterior to the 
latter is an irregular row of 7 similar spines. Posterior femur dark brown
