Choerilus variegatuSj Simon, subsp. nigricolorj nov. 



At once recognizable from the typical variegatus by ha vino- 

 the dorsal surface, tail, legs, and palpi of a uniform dull 

 black, the sterna and coxal areas dull brown and not mottled 

 and variegated with yellow. The granulation of the dorsal 

 surface and tail is also less close, and the lower surface of 

 the first and second and often of the third caudal segments is 

 smooth, the keels being obsolete, at least on the first and 

 second. In variegatus the second and third segments are 

 granular and granularly carinate below.

Genus Parabuthus, Poc. 



Parahuthus jlavidus, sp. n. 



Allied to P. cape7isis, Hempr. & Ehrenb. { = planicauda 

 Poc), but differing in having the ocular tubercle larger, and 

 the tail thinner and lower, \^ith the four inferior keels on the 

 Becond and third segments much more strongly elevated 

 posteriorly, the upper surface of the first mesially and nor- 

 mally longitudinally excavated, and the lateral and inferior 

 intercarinal spaces of the tail sparsely and weakly granular • 

 in planicauda the sides and lower surface of the tail are 

 closely and coarsely granular, and the upper surface of the 

 first is not excavated. It al^o differs from raudus of Simon 

 at least in having the inferior keels of the first caudal seg- 

 ment granular.
