breadth ; anterior pair separated by an interval nearly equal 

 to space occupied by hind-pair, form with them a trapezoid 

 wider in front than long ; laterals smallest of eight, posited 

 obliquely, about an eye's diameter apart, on well-developed 

 projections. 



Falces light-brown, approximating to olive-green ; slender, 

 plainly arcuated, convexities directed towards each other, in- 

 clined inwards. 



Maxilla pale greenish-brown, base mottled with olive- 

 green ; rather short, gradually dilated, rounded. 



Labiiim darker than maxillge ; about one- fourth wider than 

 long, round-pointed. 



Sternum greenish-fulvous, clouded with deep olive-green ; 

 cordate. 



Legs fulvous, reflecting reddish and olive-green tints ; 

 thighs marked beneath with three broken olive-green annuli ; 

 indications of ochraceous or green rings on tibial and metatarsal 

 joints ; hairs whitish, sparse ; spines moderately long ; light- 

 brown, base dark; tibiae of first and second pairs well armed 

 along second half, inner side. 



Palpi : Humeral and cubital joints have the tints and reflec- 

 tions of legs ; former article of somewhat even thickness ; pars 

 cubitalis, viewed from above, ovate ; projects from extremity 

 two strong bristles ; radial joint dense olive-green ; strongly 

 developed on inner side, represents a vertical segment of a 

 circle, pointed below ; projects forwards, at a right angle, 

 from the more tumid superior end a yellowish, membranous, 

 dilated, bicornate process ; two dark ocelli occur contiguous 

 to border ; springing from margin above the latter spots is a 

 wide organ, whose somewhat rapidly compressed fore-half 

 extends just beyond the light process above it ; lamina 

 fulvous, densely clouded with blackish -green ; sparingly 

 haired ; broad-ovate, inner side deeply impressed, projects 

 forwards well above bulb ; base produced on outer side into a 

 dark mahogany-coloured, up-curved process of the normal 

 form ; outer shell of genital bulb somewhat pyriform or sub- 

 discoid, consists of three lobes or cutaneous folds ; upper and 

 lower bright straw-colour ; central and somewhat more tumid 

 lobe chestnut ; lower lobe much the largest, upper rather the 

 smallest of the set. A front view of bulbus discloses, on inner 

 side, a yellowish, elongated, gradually-dilated, bifid mem- 

 brane, whose inner extremity is truncated and drawn out into 

 an acute process ; contained between the above-mentioned 

 processes is a dark, mahogany-coloured, crumpled lobe, pro- 

 longed into a moderately wide, emarginate appendage. 



Abdomen triangular -ovate, depressed above ; humeral 

 tubercles fairly well developed. Ground-colour whitish, faint- 

 purple tint, closely flecked with purple-lake dots, which
