defined ; profile-contour rises from thoracic junction at an 

 angle of 25°, slightly curved across cephalic part ; clypeus per- 

 ceptibly retreating, height equals two-thirds of a fore-central 

 eye. 



Eyes of fair size, seated on dark-hrown oval spots ; pos- 

 terior row sensibly procurved, eyes about equidistant, centre 

 pair rather more than their radius from each other ; anterior 

 row moderately recurved ; median pair removed from one 

 another by an interval slightly exceeding their radius, and from 

 side-eyes by scarcely that space, form with hind-pair an oblong 

 figure rather longer than wide in front ; laterals about one- 

 fourth the smallest of eight, posited obliquely, less than their 

 radius apart, on low, dark, tubercular eminences. 



Legs light-yellow, green tinge, shading off forwards, espe- 

 cially on fore-pairs, to an orange-yellow ; coxae of posterior 

 pair marked with a large olive-brown spot ; three more or less 

 pronounced red-brown or olive-brown anuuli on femora ; 

 patellary joints similar tinge ; tibias three annulations, central 

 and apical very broad, less so on hind-pairs ; metatarsi of fore- 

 pairs have the deep colour of annuli ; central and terminal 

 rings on metatarsal joints of hind -pairs; legs moderately 

 slender ; hairs fine, somewhat sparse ; spines slender, 15 on 

 femora of fore-legs, less on other pairs ; patellae project a 

 strong spine ; tibia3 of first, 9 ; of second, third, and fourth, 

 about 7 ; metatarsal joints, about 5 spines. 



Palpi light brownish-yellow ; slender, length 6nnn. ; hu- 

 meral joint rather shorter than cubital -f radial together, 

 perceptibly incrassated ; pars cubitalis about one-half length 

 of penultimate joint, strongly convex above ; bristle rather 

 short ; pars radialis tapers moderately to base, projects a short 

 process above, on inner side ; two faint rings ; digital joint 

 scarcely as long as radial, bulbus genitalis complex ; lamina 

 light mahogany -brown ; hairs fine, rather sparse ; somewhat 

 oval, obliquely truncated, projects rather beneath bulb; viewed 

 from outer side, genital bulb displays at base a large, reddish- 

 brown, linear, membranous process, twice as long as wide, 

 apex truncated, emarginate, convex and hairy on outer side, 

 directed forwards ; above and attached to former process is a 

 subreniform projection, apex acutely prolonged; bulb spiral 

 (plane) yellow-mahogany colour ; projecting from its truncated 

 extremity is a remarkable yellowish, triangular, membranous 

 process ; curving forwards and upwards from beneath latter 

 organ is a stout lake-black apophysis, which, viewed from front, 

 shows a rather stout lateral process ; perceptible above trun- 

 cated apex of lamina, seen from inner side, is a low dark ridge, 

 posterior end produced into an acute process ; base of bulb, 

 above lamina, shows an ovate depression ; apex produced into 

 a free, tapering, forward-directed appendage.
