WAMBA.—MAJELLA. 191 
Labium broad, broader than high, somewhat semicircular or rounded at the apex. 
Sternum subtriangular, its posterior extremity produced into an obtuse point between and a little beyond the 
posterior coxe. 
Abdomen short-oval, nearly circular, moderately convex above, with a large circular corneous-edged cavity 
at its fore extremity, into which the connecting pedicle is inserted, and a semicorneous or coriaceous plate of 
considerable size beneath the fore extremity between the spiracular openings. 
Wamba congener, sp. n. 
Adult male, length § line, or 13 millim. 
Cephalothorax, falces, maxilla, labium, and sternum yellow-brown ; legs pale yellowish, femora of Ist, 2nd, 
and 4th pairs yellow-brown ; palpi similar to the legs in colour, digital joint yellow-brown. Abdomen 
dull pale yellow-brown, thickly spotted with small white cretaceous-looking spots, and with a large 
central somewhat quadrate patch of a rather darker hue on the upperside, roughly defined by a marginal 
broken line of black spots, and near the posterior margin of the patch four white spots form a straight 
transverse line; at the hinder extremity of the upperside there are also a few irregular black spots; 
spinners short, compact, those of the inferior pair much the strongest. 
Eyes large, the hind-centrals, perhaps, rather the largest, and not quite circular in shape. The intervals 
between those of the posterior row are equal and not much more than half the diameter of one of the 
hind-centrals. The four central eyes form a quadrangle, whose anterior side is distinctly but not greatly 
longer than the posterior, the outer sides being about equal to the posterior side. The interval between 
those of the fore-central pair is about equal to two diameters, and each is near, but not contiguous, to 
the fore-lateral eye on its side. The eyes of the posterior row are all pearly-white. . 
Palpi short; radial joint rather longer than the cubital, and somewhat produced on the outer side; digital 
joint small, oval. Palpal organs simple, consisting of a small, not very prominent corneous lobe, with one 
or two small processes at their fore extremity.

MAJELLA*, gen. nov. (fam. Thomiside ; subfam. Aphantochiline). 
This genus is closely allied to Bucraniwm, Cambr., but may be easily distinguished 
by the different position of the eyes: in Bucranium those of each of the two rows are 
equidistant from each other, while in the present genus the two centrals of each are 
nearly or quite double the distance from the laterals that they are from each other ; 
the height of the clypeus is also greater in Majel/a than in Bucranium, and the 
cephalothorax is longer and flatter. 
Majella affinis, sp. n. 
Female (? adult), length 2 lines. 
Cephalothorax yellow-brown, much marked on the sides, but less on the caput, with deep rich red-brown 
(approaching to black) patches and suffusions. The surface is thickly covered with minute shining 
tubercles of a yellow-brown hue, with a few whitish-yellow tubercles of a much greater size and promi- 
nence, and each is surmounted by a short, strong, obtuse spine. Of these latter tubercles, five form a 
conspicuous angular line stretching across the clypeus ; there are four others—one alittle way behind each 
of the fore-central eyes, and one on each side inside the base of the prominences bearing the hind-lateral 
eyes,—one, much smaller, exactly midway between the hind-central eyes, and three, similarly small, 
in a transverse slightly curved line towards the occiput ; behind these are two others just before the 
beginning of the thorax, much larger, but forming a shorter transverse line than the three in front of 
them, and each bearing two spines; one other tubercle, the largest of all, is situated on each side 
towards the hinder part of the thorax.
