[I subjoin descriptions of two new species of Parabuthus allied 

 to liosoma. 



PaEABUTHFS GRANIMiVNUS, sp. n. (PI. IX. figs. 4-4^,) 

 ?Buthus villosus, Simon, Ann. Soc. Ent. France, 1890, p. 130; not of 

 Peters. 



2 . Colour of trunk and palpi reddisli or blackisli brown ; tail 

 witb segments 1 to 3 clear yellowish brown, segments 4-5 and 

 the vesicle piceous, the 5tli segment of the tail rather paler 

 beneatb than the 4th ; mandibles, legs, and sternal surface of the 

 trunk clear ochre-yellow, the femora of the legs sometimes a little 

 darker than the rest of the segments. 



Trunk a,s in P. liosoma; carapace granular throughout, except 

 for a smooth area on each side of the tubercle. 



Tail almost six times the length of the carapace, nearly 

 parallel-sided ; segments 1 and 4 equal in width, 2 and 3 very 

 slightly wider than the 4th, the segments all low, as in liosoma, 

 the 4th a little lower than the first ; all long and narrow, with 

 sides lightly convex, much longer as compared with their width 

 than in liosoma, all much longer than wide, the width of the 4th 

 a little less than the length of the 1st and much less than the 

 length of the 3rd (in liosovia the width of the 4th is much greater 

 than the length of the 1st and equal to that of the 3rd) ; the 

 vesicle large, its width equal to the width of the lower surface of 

 the oth segment between the keels {cf, measurements). 



Palpi more coarsely granular than in liosoma ; the mauus, 

 instead of being smooth as in liosoma, is covered thickly with 

 squamiform granules ; moreover, it is wider than in liosoma, 

 being slightly wider than the brachium, which is coarsely granular 

 all over. 



The first abdominal sternum beneath the pectines perfectly 

 smooth (finely granular anteriorly and laterally in liosoma). 



S . Difieriug from the 6 of liosoma in exactly the same fea- 

 tures as the $ ; the manus considerably wider, with the digits 

 lobate as in P. Hunteri. 



Measuremerds in millimetres. — d • Total length 96, length of 

 carapace 9*8, of tail 62 ; length and width of the segments — 1st 

 8, 7 ; 2nd 9, 7-3 ; 3rd 9-5, 7-3 ; 4th 11, 7 ; 5th 11*5, 6-5 ; width of 

 vesicle 5 ; width of brachium 3*3, of hand 5 '2 ; length of hand- 

 back 7'3, of movable digit 8"7. 



$ . Total length 110, of carapace 12"5, of tail 72 ; length and 

 width of the segments— 1st 9-2, 8-2 ; 2nd 10-4, 8-8 ; 3rd 10-6, 8'8 ;
