ocular tubercle large, bristly in front, the distance bet'.veen 

 the eyes exceedino; a diameter. 



Mandihhs bristly, the upper fang moderately curved at tlie 

 apex, furnished with 11 teeth, 8 in a continuous line and 3 on 

 the inner side near the base ; of the 8 constituting; the long 

 series the 2 distal ones are large, subequal, and blunt, then 

 comes 1 small one, then 1 large, and these are followed by 4 

 medium-sized teeth, which form the outer row at the base of 

 the fang ; the lower movable fang is furnished with 2 large 

 widely separated teeth and a very small one between them. 

 The inner surface of the mandible convex, the stridulating- 

 ridges long and strong ; feathery hairs at the base of the 

 upper and lower digit. 



nostrum horizontal, compressed, its upper edge straight; the 

 tips of its upper and lower lips on a level with each other. 



Palpi moderately robust, clothed with short hairs inter- 

 mixed with long setffi, some of which on the lower surface of the 

 tibia are short and spiniforra ; tibia stouter in tlie middle 

 than at the ends ; the tarsus a little narrowed at the base, 

 but immovably united to the tarsus. 



Legs. — First and fourth unspined ; tibia of second armed 

 above with 5 spines, of third with 3 ; femora of fourth a little 

 enlarged and compressed.

The discovery of a representative of Sc. valida on the con- 

 tinent of Africa is of great interest, the species being hitherto 

 known from the Canary Islands {valida, typical form), 

 S. Arabia (subsp. desertieola), the Persian Gulf (subsp. 

 persica), and Socotra (subsp. Ba^fouri). The conclusion that 

 the species once occupied the whole of the Mediterranean area 

 that lies between the most easterly and westerly points of its 

 present range can hardly be doubted ; but there is at present 

 no evidence that it exists in Africa between Egypt on the 

 east and Morocco on the west.
