Stcrnites eacli with a deei), Y-shaped inipressicn, the branches widely diverg- 

 ing, at or caiidad of the middle, the angle ^■cry obtuee, the ends transverse. 



Dorsal plates bisulcate from the first caudad. 



Length, 75 mm.

Paurcplyx, gen. now 



Tn this genus there is a short series of seta' or cilia <>n or projecting from 

 beneath the free edge of each lateral piece of the labrum at its mesal end. The 

 mesocaudal angle of each lateral piece of the labrum is typically more strongly 

 produced than in Mecistocephalus. The first lamina of the mandible has from 

 ten to sixteen teeth in the known species, the series of teeth being ccntinued 

 proximally by a series of characteristic serrations along the mesal edge of the 

 mandil)le. 



Genot>"pe. — P. himalayanns, sp. \\o\ . 



The known species are all from India. 



Paurcptyx himalayanus, sp. nov. 



The median piece of the labrum in this species projects caudad beyond the 

 edge of the main part of each lateral piece; each lateral piece adjacent to the 

 metlian piece produced caudad into a long acute tcoth somewhat like but pro- 

 portionately much longer than the corresponding processes of P. superior and 

 P. pallidus. Labrum with seta' showing at mesal end at a near angle formed 

 by mesal process and main part of plate, these in part, at least, merely stiff 

 hairs projecting from beneath (i. e., from dorsal surface) the edge and similar 

 to the other hairs clothing the dorsal surface. Mandibles with nine pectinate 

 lamella of which the first is ten-toothed; the inner margin below these teeth 

 conspicuously serrate. A median lamella has about thirty-eight teeth which 

 decrease from the distal end proximad in the usual wa\'. Head LO times, or 

 slightly less, longer thiin wide. Anal legs UKjre than twice as long as the penult. 

 Last sternite large, more strongl>- narrowed caudad than in pallidus but similarly 

 constricted in front of caudal end ; broader in male, the caudal lobe more abruptly 

 set off. 



Colour uniform fulvous to light brown, the legs con(-olorous. Head and 

 prehensorial segment abrupth' darker, chest ni.il to mahogany. Antenna' 

 fulvous. 



Length to GO mm.; width of first plate, 1 .8 nun. 



Pairs of legs, forty-nine.
