A form from Beirut described by Simon as //. maurus, 

 var. herijtensis (Ann. Soc. Ent. Fr. 1884, p. 192), which I 

 overlooked in the above-cited paper on Heterometrus, and 

 which is also omitted from the ' Tierreich,' apparently differs 

 from //, fuscus in having- the femur of the chela smooth 

 above.

 Buthus dmiidiatus, Sim. Ann. Mus. Geneva, xviii. p. 244 (1883). 



Loc. Dthala and El Kubar. 



Common in S. Arabia and Perim Island. 



The typical form of scaher from Arkiko, in Abyssinia, 

 apparently differs from the Arabian form described by Simon 

 in the much paler colour of the dorsal side of the trunk.

$ . — Colour. Head infuscate, paler in the middle, darker 

 than the yellowish mandibles, which have two weakly fuscous 

 stripes ; palpi and legs pale, only the femora tinted with 

 brown ; terga of carapace and abdomen brownish. 



Width of head in adult approximately equalling length of 

 tibial (penultimate) segment of palp, and the same segment 

 of the fourth leg. Upper and lower jaws of mandible with 

 one minor tooth ; sometimes a trace of a second minor tooth 

 on the lower jaw. 



Palp with its femur spined beneatli, apparently as in 

 G. arabs ; the patella armed beneath with seven or eight pairs 

 of very long spines, for the most part alternately longer and 

 shorter, the longer being slightly thicker than the shorter. 

 Tibia armed beneath wuth eleven pairs of spines : the six 

 corresponding to those found in the male shorter than the 

 others, but mostly exceeding the height of the segment; the 

 rest, corresponding to the long setaj found in the male, much 

 longer but scarcely thinner than the others. Tarsi of second 

 and third legs typically armed with 1, 2, 2, 2 spines, the 

 distal pair being on the distal segment; tarsus of fourth 

 with 2, 2, 2, 2 spines typically, sometimes an extra basal 

 spme in front ; terminal segment always without spines.
