lake-black ; laminae bulbi yellowisli-browu, passing into olive- 

 green on fore-end ; directed to^Yards each other ; haiis coarse, 

 sparse ; inversely ovate, broad, strongly convex ; rise above 

 bulbus ; lamina on outer side exhibits a large moderately-deep 

 concavity — segment of a circle — of nearly its own length, 

 margin — base of segment intact, lake-colour : base of lamina 

 at termination of cavity prolonged into a twin, submembranous. 

 brownish, curved process, apices directed outwards : project- 

 ing from a ring on summit of lamina is a long, conspicuous, 

 dark, cylindrical process, obhquely truncated, on its outer side, 

 for nearly whole length; lobes of bulb wide, subvertical ; fii"st 

 lobe of somewhat even width, figured with a blackish cihate- 

 like mark; second lobe -rapidly compressed below, prolonged 

 into a strong, black, forward-curved apophysis ; above the 

 latter organ is a large, broad, pitted, brownish-yellow, up- 

 curved process ; anterior appendage, viewed somewhat in 

 front, represents a rather large compressed or pinched mem- 

 branous process curving downwards to the large yellowish 

 process. 



Abdomen broad-oviform, depressed, sides abiTipt, humeral 

 tubercles large, conical, project outwards and backwards ; 

 profile of abdomen somewhat diamond-shaped ; sparingly 

 clothed with orange and black bristle-like hairs ; stone-colour, 

 approximating to ohve-gi"een : design fonned by a series of re- 

 curved irregular bands, composed of creamy-stone, purple 

 margined and spotted, fi-ee and coalescing flecks ; bands angu- 

 lar and more defined on posterior slope ; lateral margins 

 bordered by a brown band without very determinate limits ; 

 ventral field olive-stone colour, displays a broad transverse 

 band of mixed normal colours. 



Femtna. — Ceph.-th., long, 3: wide, 2. Abd., Ions. 3: 

 wide, 2-5. Legs, 1, 2, 4, 3 = 14. 101, 88, 6-5 mm. 



Cephahthorax brownish-orange, hghtly shaded, chiefly on 

 grooves and margins, with black-brown ; splashed, lake-coloured, 

 bifurcating line extends fi'om limit of caput to posterior lateral 

 eyes ; triangular lake mark on chipeiis ; hairs sparse, black, 

 bristle-like ; cephalothorax equal in length to metatai-sal joint 

 of first leg ; oval, fau-ly compressed forwards ; pars cephalica 

 strongly convex, roundly truncated, lateral index scarcely 

 equals facial ; eye-eminence well developed : clypens outwardly 

 inclined, depth exceeds space between a fore-central and later^ 

 eye next to it ; an angular furrow beneath anterior row of eyes 

 gives its tumid sides a conical (piano) form ; pars thoracica 

 convex ; large circular depression on posterior slope ; normal 

 grooves faint ; profile-contour rises from thoracic junction at 

 an angle of 45", shghtly cui-ved across caput. 



Posterior row of eyes perceptibly procurved, centrals sepa-
