Ncio South African Scorpions. 5 



Locality. All the specimens described above, namely, 5 females, 

 3 males, and 30 young of all ages, were taken by me at the village 

 of Prince Albert, Cape Colony. 



Further localities are : 



Laingsburg (Buffels Eiver), Prince Albert Div. : 1 adult female 

 and 16 young of both sexes, agreeing with those from Prince Albert 

 in every respect. 



Beaufort West: 1 adult female (Rev. G. Fisk), 4 adult males and a 

 large number of young (collected by myself). These male specimens 

 are smaller, the largest being only 99 millim. long; the granulation 

 of the sterna is either as in the male of the type or the anterior 

 segments may be rugose in the middle and granular only at the 

 sides ; the widened part of the median groove in front of the eye- 

 tubercle is often smooth. In all other respects these specimens 

 resemble the type. 



Victoria West : 1 male (R. 3/. Lightfoot), resembling those from 

 Beaufort West in size, &c. ; the anterior sternites of the abdomen 

 are rugose in the middle and granular at the sides. 



The area occupied by this species includes the driest part of 

 the Great Karroo, known as the Gouph. West of the Buffels Kiver 

 it is replaced by 0. austenis (at Matjesfontein and Touws Eiver), 

 while northwards it extends to Victoria West and probably much 

 further. The scorpion lives in shallow excavations under stones on 

 the tops and sides of small hills, but does not seem to make deep 

 burrows in the earth as most of the species of the genus do. :;: In 

 the structure of the palps in both sexes this species closely resembles 

 0. palUdipcs and 0. pcrinyucyi. 



OPISTHOPHTHALMUS GIGAS, n. sp. 

 Type : Female (in alcohol). 



Colour reddish brown ; the interocular area, legs, vesicle, and 

 tinder side of abdomen reddish yellow (probably pale-yellow in fresh 

 specimens) ; hands yellowish brown above at the inner basal part; 

 the granules on the sides of the carapace and those on the crests 

 of the palps dark olive-green, nearly black ; fingers and distal 

 part of finger-keel nearly black ; mandibles reddish, brown, not 

 blackened. 



This specimen resembles the female of 0. karrooensis so closely 

 that I need only point out the differential characters as follows : 



* Mr. Max Schlechter informs me that 0. pallidipes, which he found in con- 

 siderable numbers in the Divisions of Clamvilliam and Calvinia, also lives simply 

 under stones without constructing deep burrows in the earth.
