Loc. Marocco and Algeria. The British Museum lias 

 many examples from Tangier {B. B. Woodward, dtc), Cape 

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

Loc. Egypt: Cairo [Dr. Anderson). 



Hem])rich and Ehrenberg iveognizid two varieties of the 

 Egyptian species — one from Alexandria, which was named 

 flavus; tlie 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 //. pnlmatus 

 Jiavus, belongs to quite a distinct species from the Algerian 

 H. maurus. 



(3) Ileteromefrus fusctiSj Ilempr. & Ehrenb. 



Heterometrua palmatusfuscus, Ilempr. & Ehrenb. Symb. Phys., Scorp. 



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

 Heterometrus palmatus, var. minor, Simon, ibid. 

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



(169S); Ivraepelin, op. cit. (nee testaceus, C. Koch). 



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

 Woodxonrd) , &c. 



Birula seems to have recognlEed 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 prop inquus, Simon. 



Heterometrus propinquus, Simon, Ann. Soc. Ent. Fr. (6) ii. p. 259 

 (lb72). 



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, unfc rtunately, did not determine the sex of his 

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

 smoother than specimens of IL/uscus, 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 : —
