8 SECOND YlEKANJ) MISSION. 



The sternum is like the cephalothorax in colour, and of a regular oval form, pointed 

 behind ; it, like the maxillae and labium, is clothed with fine brownish hairs. 



The abdomen is of a short oval form, blunted at each end, and tolerably convex above 

 it is of a pale clay-colour, covered thinly with yellowish-brown hairs ; the four exterior 

 spinners are moderately long, and of nearly equal length ; the genital aperture is rather large 

 and of characteristic form.

Adult male : length 3f lines. 



The cephalothorax is very similar in form to that of D. infletus, though rather narrower 

 in front ; its colour is yellow-brown, and it is clothed pretty thickly with grey pubescence. 



The eyes are rather small, but placed in the usual two transverse curved rows ; the 

 foremost row, which is the shortest, is nearly straight, the hinder one considerably curved 

 and the curves of both have their convexities directed backwards. The eyes of the hinder 

 row are equidistant from each other, those of the central pair of this row being rather the 

 smallest of the eight; those of the fore-central pair are the largest, and form a line longer 

 than the hind-centrals, the interval separating them being about equal to an eye's diameter, 

 and each is very nearly contiguous to the lateral of the same row next to it. The eyes 

 of each lateral pair are placed a little obliquely, and are rather nearer together than 

 those of the hinder row are to each other ; the longitudinal diameter of the trapezoid formed 

 by the four central eyes is considerably greater than the transverse one ; the height of the 

 clypeus is about equal to the diameter of one of the fore-central eyes. 



The legs are strong and of tolerable length, and rather lighter in colour than the 

 cephalothorax ; their relative length is 4, 1, 2, 3, and they are pretty thickly clothed with 

 sandy-grey hairs (among which are some of a browner hue), bristles, and spines ; some of the 

 latter are beneath the metatarsi and tibiae of those of the 1st and 2nd pairs, but the greater 

 number are on the tliird aud fourth pairs. Each tarsus terminates with two claws, beneath 

 which is a small claw-tuft ; and beneath the tarsi is a scopula extending a little way 

 underneath the anterior portion of the metatarsi. 



The palpi are short, tolerably strong, and similar in their colour and armature to the 

 legs. The humeral joint has several black spines on its upper side ; the cubital joint is 

 stronger and a little longer than the radial; the latter is furnished with longish bristly 

 hairs, and expands at its fore-extremity, which is prolonged on the outer side into a tolerably 

 strong, rather tapering, reddish-brown, apophysis, terminating in an obtuse, flattened, corneous 

 point ; the digital joint is large, oval, and of a browner hue than the rest ; the palpal organs 

 are prominent and well developed ; they are of a yellowish colour, traversed near the middle 

 by a distinct yellow-brown spine-like fillet or band, close in front of which is a strong, 

 curved, tapering, reddish-yellow-brown corneous process, with another very similar, but 

 smaller, in front of it ; a third, smaller still and apparently obtuse, being in front again, just 

 below the fore-extremity of the joint. 



The f aloes are neither very long nor strong; their direction is nearly vertical, and they 

 are similar in colour to the cephalothorax; their front surface is clothed with greyish 

 pubescence and some brown hairs and bristles.
