472 un. K. I. pococK on the 



wide as the head and the first tergite, about twice as wide as 

 long. MaxilUpedes weak. Tracheal sclerites in contact with 

 the tergites. Forous area apparently situated transversely upon 

 the posterior portion of the sternites. 



In the form of the head, basal plate, and antennae this genus 

 seems to resemble Orphnceus, but it differs very markedly from 

 it in the structure of the anal somite, with its large pleurae, 

 thick, legs, &c. ; moreover the tracheal sclerites are in contact 

 with the tergites. 



In the position of its sternal pores it resembles Geophilus, but 

 it may be readily recognized by its short thick antennae, wide 

 basal plate, &c.

Sead thickly setose ; antennce with their segments wider than 

 long, the apical conical. The coxae of the viaxUlipedes largely 

 overlapped on each side by the pleural sclerites ; without clii- 

 tinous lines, the anterior border lightly emarginate ; femora 

 short, unarmed, the joint of the claw falling far short of the 

 anterior border of the head. Tergites thickly hairy, not bisulcate, 

 Sternites also hairy.. 



Anal somite setose, wide, the tergite as wide as that of the 

 preceding ; leg-bearing somite like a half-moon, with the con- 

 vexity posterior ; pleurce large, projecting laterally far beyond 

 the margin of the tergite, without pores above, but possibly 

 porous close to and beneath the sternite, densely hairy ; sternite 

 of moderate size, triangular, with truncated posterior end. Legs 

 enormously stout at the base, the first segment as wide as the 

 pleura, gradually tapering towards the distal segment, compressed, 

 hairy, not tipped with a claw, or at least with only a minute one. 

 The rest of the legs thickly hairy. 



Number of pairs of legs 49. 



Length up to about 13 mm. 



Two examples (Pj) from St. Vincent {H. S. Smith), one at 

 an altitude of 1500 ft,, tbe other in moss in the forest at an 

 elevation of 3000 ft.
