Legs, femora of two first pairs, basal third brownish- 

 yellow, fore-end orange-brown, clouded with lake-brown ; a 

 ioroad, broken, brown ring intersects the light and darker 

 shade ; patellar joints have the deeper colour of femora ; tibias 

 yellowish, green tinge, fore-third normal brown ; metatarsi 

 yellowish, faint, wide, greenish central and apical annuli ; 

 tarsi yellowish, passing into a darker hue ; femora of hind- 

 pairs have a deep red-mahogany shade ; broken ring on third 

 pair is separated from darker parts by a light streak ; patellae 

 normal hue ; tibial joints have two not well-defined reddish- 

 browm annulations on fore-half ; annuli on metatarsal joints 

 reddish ; legs moderately stout ; hairs sparse, yellowish ; 

 femoi'a of first and second pairs, 12 or 13 moderately strong 

 black spines beneath, 8 or 9 above ; 4 or 5 small spines 

 on patellae ; tibial joints of first, about 13 irregular spines ; 

 second pair less ; metatarsi about 7 ; femora of fourth pair, 

 5 or 6 beneath on fore-end ; of third pair, one spine ; spine 

 armature of other joints does not differ greatly from first 

 pairs. 



Palpi, humeral joint yellowish ; increases somewhat in 

 width forwards, scarcely twice length of cubital + radial joints 

 together ; cubital joint yellowish, broad-oval, squarely trun- 

 cated in front, projects t'svo long bristles ; radial similar tinge, 

 short, convex on inner side, produced on outer into a long, 

 broad process, acutely truncated on posterior side, few coarse 

 hairs ; lamina brownish-yellow, clouded ; moderately hairy ; 

 placed rather beneath bulb, base developed into a stout coni- 

 cal projection, directed inwards, curving somev;hat upwards, 

 in length nearly equals distance from its own base to apex of 

 lamina, more than half as broad as long ; base of lamina pro- 

 longed on outer side into a large red-brow'u apophysis, directed 

 backwards, curved forwards, concave in front ; most remark- 

 able appendages of genital bulb— suspended near base is a 

 somewhat quadrate, dark membrane, concave in front, inner 

 angle prolonged into a strong tapering apophysis, whose 

 length about equals breadth of membrane at base ; next to the 

 latter appendage is a yellowish, oval, vertical organ, convex 

 behind; directly in front, between two dark, backward-curved, 

 stout processes, is a yellowish membrane, convex on anterior 

 face, rapidly constricted into a fine apophysis curving back- 

 wa.rds to the above-mentioned vertical organ. 



Falccs reddish-brown ; conical, vertical, as stout as the 

 femur of a fourth leg. 



MaxiUcs brownish-yellow, base clouded ; nearly as broad as 

 long, roundly pointed. 



Labium, apex pale, base dark-brown ; nearly as long as 

 wide, somewhat pointed, transverse groove forms a collar-like 

 base.
