New South African Scorpions. 3 



Brachium with its granular superior surface well defined by two 

 coarsely granular crests ; the posterior surface elevated crest-like 

 along the middle with rows of coarse granules ; the anterior surface 

 more finely granular, the basal tubercle strong. Hands moderate, 

 depressed and moderately convex above, the length of hand-back 

 equalling the breadth of hand, the finger-keel strong and nearly 

 smooth ; inner part of upper surface of hand nearly smooth, covered 

 with a network of punctate anastomosing ridges, which are just 

 perceptibly raised above the surface level, these ridges often replaced 

 by low granules near the anterior (inner) and the distal borders and 

 along the finger-keel, the two secondary keels obsolete but their 

 position indicated by dark lines ; inner edge of hand coarsely granular ; 

 outer part of upper surface of hand coarsely granular, the granules 

 often forming a crest in the middle. 



Legs. Femora minutely granular, with a row of coarser granules 

 on their upper and lower edges excepting on the upper edge of the 

 first pair ; tarsi of the last two pairs of legs with 2-3 external and 

 5-6 internal spines below, in addition to the 4 external and 5 

 internal spines on the lobes ; superior process much shorter than 

 the lateral lobes. 



Opcrculum subcordate, somewhat broader than long, emarginat3 

 behind but not cleft longitudinally. 



Pectincs extending beyond the apex of fourth coxas, with 20-21 

 teeth ; scape rounded at the base behind and free of teeth for about 

 one-fourth of its length. 



Measurements in Millimetres of largest female. Total length 110 ; 

 greatest length of carapace 16 ; * width of carapace 15 - 8 ; distance 

 of eyes from anterior margin 11 ; width of hand 11^- ; length of hand- 

 back 11^, of movable finger 16, of tail 55 ; width of first caudal 

 segment 5^, of fifth caudal segment 4, of vesicle 4. 



Male (recently killed, in alcohol}. 



The adult males show the following differential characters : 



Colour. Abdomen darker above. 



Carapace only slightly longer than the first and second caudal 

 segments ; its interocular area with a few minute granules at the 

 anterior lateral angles and in the depression in front of the eye- 

 tubercle. 



Terga very densely, finely and evenly granular throughout, coarsely 

 granular only at the sides of the last segment. 



: The carapace is broader in proportion to the length in this specimen than is 

 usually the case.
