little-known Thelyphonidae and Solifugae. 303 



Loc. Mashonaland : Salisbury [G. A. K. Marshall). 



Only one species of the genus Blossia is up to the present 

 time known, namely B. spinosa of Simon (Ann. Soc. Ent. Fr. 

 1880, p. 400), from Lower Egypt and Algeria. The genus, 

 however, has been recorded from S. Africa by Kraepelin, 

 who mentions but refrains from naming, except as doubtfully 

 spinosa, some females procured at Moritzburg (? Pieter- 

 maritzburg). More probably these females belong to the 

 species here described, which at least differs from B. spinosa 

 in the dentition of the jaws of the mandible. In B. spinosa 

 the fourth tooth of the upper jaw is a little larger than the 

 first and second, and in the lower jaw there is only one 

 intermediate minor tooth.
