Scorpions of the Genus Broteas. 101 



palpi paler reddish brown ; much less distinctly granular, the 

 tergites in the female densely punctured, in the male coarsely 

 coriaceous or very finely and closely granular ; granulation 

 of carapace not extending on to interocular triangle, which is 

 coriaceous. Lower surface of first caudal segment granular, 

 the median keels granular. 



Palpi substantially as in granimanus, but upperside of 

 hand in both sexes densely punctured, not granular. 



Pectinal teeth 9-10 ((J), 7-8 ( ? ). 



Measurements in millimetres. — Total length 50, of cara- 

 pace 7, of tail 32. 



Log. British Guiana (W. L. Sclater, type); Vryheids 

 Lust, Demerara (Turner). 



The characters of the species, of which I have examined 

 the types, may be summarized as follows : — 



a. Pectines narrow, width of shaft at base less 



than half its length; four inferior keels on 

 first and secoud caudal segments absent, very 

 weak on the third ; intercarpal spaces of 

 caudal segments 1-4 smooth, not granular; 

 abdominal terga smooth, the keels of the 

 seventh represented by four tubercles, one for 

 each keel; sterna smooth and polished, finely 

 punctulate at the sides ; carapace not granular, 

 at most rugose, with close-set punctuation ; 

 upperside of humerus of palp scarcely visibly 

 granular ; pectinal teeth 11 paraensis, Sim., $. 



b. Pectines broad at the base, the width of the 



shaft more than half the length at least in 9 > 

 second caudal segment with four inferior 

 keels, first usually with four, but the medians 

 sometimes obsolete ; intercarinal spaces of 

 caudal segments 1-4 always more or less 

 granular, except the lower surface of the 

 first, which may be nearly smooth (Gervaisii) ; 

 terga and carapace always more or less 

 granular, the crests on the seventh repre- 

 sented by a series of coarse granules or small 

 tubercles ; upperside of humerus visibly 

 granular. 

 a 1 . Carapace and terga coarsely and uniformly 



granular throughout, though the granules 



are a little smaller on the anterior portion 



of the terga ; abdominal sterna coarsely 



punctured throughout, the fifth granular 



throughout ; anteocular portion of carapace 



strongly sloped, at least to the same extent 



as in Tenthraustes ; tail coarsely and 



closely granular throughout, the inferior 



median keels of the first not traceable 



amongst the granules; hand punctured, not 



granular; pectinal teeth 7 granulatus, Sim., $.
