to midway the dactyl of the third pair. Each has the merus, carpus 

 and propodus much compressed laterally, with the upper margin of 

 the carpus and propodus subcarinate; the upper surface of the pro- 

 podus with a longitudinal line of coarse punctae; the dactyl is very 

 acuminate, tapered and thin, with a sharp tip and a longitudinal 

 groove on each surface; the propodus and dactyl have both lateral 

 margins fringed with short, golden brown setae. 



The fifth pair of legs are short, extending only to the distal end 

 of the carpal joint of the fourth pair of legs; the ischium, merus and 

 carpus of the fifth pair of legs are rather thick, the merus having a 

 subdistal spine on its outer lateral margin; the propodus and dactyl 

 are foliaceous, subovate, fringed with short setae as is also the carpus 

 and upper margin of the merus.
