Jitlle-hnoion M^eolropical Scorpions. 477 



Tail with the median keels oa segments 1-4 absent, as in 

 H, lunatus ; the inferior-lateral keels distinct and finely 

 granular, the superior and superior-lateral keels and the spaces 

 between them distinctly granular ; superior edges, lateral and 

 inferior surface of fifth caudal segment, and vesicle granular. 



Chelae: humerus with superior and anterior granular 

 crests; brachium smooth, punctured, without distinct crests, 

 the inferior crests on the anterior side alone being weakly 

 granular ; hand smooth, narrow, barely as wide as brachium, 

 its width less than length of underhand and a little loss than 

 half the length of the movable finger ; fingers in contact 

 tliroughout, neither lobate nor sinuate. 



Pectinal teeth 12-15. 



S ' — Like the female, but with the upperside of the trunk 

 more granular; the frontal area only smooth in the middle; 

 sterna also finely shagreened throughout. Chelae as in female. 



Pectinal teeth 15-17. 

 ? . — Total length 36 millim., carapace -i'h, tail 19. 



Loc. Eten (sea-level), Peru (P. 0, Simons). Several 

 adult males and females. 



Subspecies vittatuSj nov. 

 (Mountain form.) 



Nearly allied to the typical form, but much blackcir, the terga 

 being black and marked with five longitudinal yellow bands, 

 the black patches being much larger tiian in //. leopardus. 

 The inferior-lateral crests of the tail are smootiier than m 

 the typical form and the tail more robust. Male unknown. 



Pectinal teeth 14-16. 



Total length 40 millim., carapace 5, tail 25. 



Loc. Bafios, 3000 m., near Cajamarca in Peru [I'. 0.

 h-aiid ; tiugers in contact throughout in the adults 



of both sexes, neither sinuate nor lobate leopardus.
