 or hairs in all behind. Antepygidial bristle longer than second

 5th joint, hind tarsus, ventral aspect. 



Hind tibia, with row of 5 bristles on outside, dorsally placed, but below 



the edge and without intermediate bristles. A single bristle below 



this row, well above the ventral edge in the $ , practically on it in 



the $ , in which sex sometimes 2 bristles occur in this position 



(see Fig. 1.) Longest apical bristle of the second hind tarsal segment 



reaches to beyond middle of the fifth ; in one $ to base of claw. All 



the fifth tarsal joints in both sexes with three subapical ventral 



spines, of which the middle one is longest. On each side of the 



same joint, in all the tarsi, there are 4 stout bristles or spines in a 



row. Two are near the base, and after an interval, two more occur 



(see Fig. 2). Behind the central and longest subapical spine on 



the ventral surface of the fifth tarsal joint there is, in the case 



of the hind tarsus, one minute hair. More than one occur on 



same joint in fore- and mid- tarsi.
