Scorpions of the Genus Heterometrus. 363 



Loc. Marocco and Algeria. The British Museum has 

 many examples from Tangier (B. B. Woodward, cfcc), Cape 

 Spartel (T. Annandale) , Tunis, and Algiers. 



(2) Heterometrus palmatus, Hempr. & Ehrenb. 



Heterometrus palmatus, Hempr. & Ehrenb. Syinb. Phys., Scorpiones, 



no.l (1829). 

 Heterometrus palmatus favus and ? rufus, iid. ibid. 

 Scorpio maurus, Kraepelin, op. cit. (in part.). 



Loc. Egypt: Cairo (Dr. Anderson). 



Hemprich and Ehrenberg recognized two varieties of the 

 Egyptian species — one from Alexandria, which was named 

 flavus; the other from Sinai, named rufus. I have seen no 

 examples from Sinai, but a single male specimen from Cairo 

 (Dr. Anderson}, which is doubtless referable to H. palmatus 

 flavus, belongs to quite a distinct species from the Algerian 

 H. maurus. 



(8) Heterometrus fuse us, Hempr. & Ehrenb. 



Heterometrus palmatus fuscus, Hempr. & Ehrenb. Symb. Phys., Scorp. 



no. 1 (1829) ; Simon, Ana. Soc. Ent. Fr. (5) ii. p. 258 (1872). 

 Heterometrus palmatus, var. minor, Simon, ibid. 

 Heterometrus testaceus, Birula, Horse Soc. Ent. Ross, xxxiii. p. 138 



(1898) ; Kraepelin, op. cit. (nee testaceus, C. Koch). 



Loc. Syria: Jerusalem {Herr Rolle), Tiberias (A. Smith 

 Woodward) , &c. 



Birula seems to have recognized the distinctness of the 

 Syrian species, but erroneously used the name testaceus for 

 it : testaceus was applied by C. Koch to a specimen from 

 Algeria co-specific with maurus of Linn. 



(4) Heterometrus propinquus, Simon. 



Heterometrus propinquus, Simon, Ann. Soc. Ent. Fr. (5) ii. p. 259 



(1872). 



Loc. Syria : Damascus and Nablous. 



This species is said to differ from the preceding (H. fuscus) 

 in having the median eyes larger, the vesicle more globular, 

 and 14 pectinal teeth. 



Simon, unfortunately, did not determine the sex of his 

 specimens ; but since the type of //. propinquus is said to be 

 smoother than specimens of H. fuscus, it is safe to assume that 

 the former species is based upon the female sex. 



To the above-mentioned I have to add the following new 

 forms : — 



(5) Heterometrus arabicus, sp. n. 



Colour a nearly uniform yellowish brown, the legs and tail
