^- . tii '- ir i. ; r- 



Body utout, Mxmcnted, with latent! procewe* clone together. 



ProboacM long, tain-ring and carved near the extremity. 



Cbelifori abwnt. 



Palp* 6-jointed ; terminal joint articulated to one Ride of the penultimate. 



Ovigen 6-jointed ? 



Legs abort, firat oozn anned doraally with two spurs. 



Abdomen long and slender. 



This is a diminutive species ; the entire animal does not cover a space 8 mm. 

 square. 



The trunk is stout and distinctly segmented ; the lateral processes are not widely 

 separated, hut as they are rather short and tapering, the 'intervals at their distal 

 extremities are very pronounced. The first coxae, which are the largest, all hear 

 dorsally a pair of stout tubercular spines which are very prominent. Each of the four 

 segments of the trunk hears a stout tubercle of some elevation in the middle line, and 

 close to its posterior border. 



The Cephalou is scarcely expanded, and almost fills the interval between the first 

 pair of lateral processes and their first coxae. Anteriorly it bears a very long Ocular 

 tubercle which is directed obliquely forwards, flask-shaped and truncated at its extremity, 

 on the upper surface of which, in a compact group, are four very well-developed eyes. 



From the truncated end of the trunk the Abdomen projects horizontally ; it is rather 

 long and not separated by an articulation. On the ventral surface of the trunk a 

 slightly raised Irniid passes transversely between the first three pairs of lateral processes, 

 with the last pair the hand is interrupted in the middle line. 



The Proboscis is long and of a peculiar shape, not unlike the snout of a weevil 

 beetle. It is movably articulated to the body, and for about one-third of its length it 

 is not disproportionately slender, then it tapers rather rapidly to a long and very 

 slender structure, curved downwards near the tip. It is quite smooth and presents an 

 annular appearance which is less distinct proximally. 



The Chelifori are quite absent 



The Palps are six -jointed and arise above but well to the side of the proboscis 

 (fig. Ib). The first joint is short and very stout, the second is long and extends 

 beyond the extremity of the ocular tubercle. Tin- third is very short and its distal 

 limit indistinct The fourth joint is rather more than half the length of the second. 

 The second joint U-ars the stumps of several spinous setae along its length ; on the 

 fourth joint a .similar numltcr of curved spinous setae occur, and these increase in size 

 to the distal extremity of the joint, which also bears a few finer setae and a small 

 distal fringe. The last two are quite small and rather densely clothed with small set. 

 The last one is articulated to one side, and not at the end, of the penultimate, and 

 the set occur mainly on the outer side.
