hco new Genera of Scorpions. 47 



(lifFers in fact in the form of the sternum. Of all tlu; o-encra 

 of Butliida* it certainly comes nearest to Butheolus of Simon 

 {(Jrihodacij/IuSj Karscli) ; but although the sternum in 

 Butlieohis is more ])entagonal (? always) than in the otliers, 

 it is not so markedly wide as in Ileterocharmus. In Buthe- 

 olus, again, the cephalothorax has its frontal portion sloped, 

 while in this new genus it is horizontal. Nevertheless the 

 two are undoubtedly very closely allied. 



If, again, Ileterocharmus be compared with the known 

 genera of other families, the only one with which it presents 

 any affinity is Gharmus of Karsch, a genus which this author 

 referred to the lurini. But between these the affinity appears 

 to be very great, so far, indeed, as can be judged from the 

 somewhat meagre description that Karsch has given. In fact 

 no generic differences are to be discovered. But I find it 

 hard to believe that any author familiar with scorpions should 

 have placed a species congeneric with the one now before me 

 in close proximity with such forms as luriis, Scorpiops, &c. It 

 is almost incredible that the Buthoid characters above men- 

 tioned can have been wholly overlooked. I consequently feel 

 compelled to assume that some differences which do not 

 appear in the description do in reality exist between Gharmus 

 and Ileterocharmus. 



Heterocharmus cinctipes, sp. n. 



Colour. — Trunk above and tail fuscous, the former ob- 

 scurely variegated with fulvous ; vesicle ferruginous ; 

 ventral surface pale ; palpi testaceous, brachium with a 

 fuscous baud, manus infuscate ; legs fuscous, with testaceous 

 joints. 



Gephalothorax convex, about as wide as long, nearly as 

 long as the first two caudal segments, weakly but closely 

 granular throughout, the anterior margin nearly straight, the 

 trontal region lightly depressed in the middle, the shallow 

 depression extending over the ocular tubercle to the hinder 

 margin ; the ocular tubercle prominent, the eyes large and 

 separated by a space about equal to a diameter. 



Tergites granular, more coarsely but less closely so than is 

 the cephalothorax, the first without tlie median keel, the last 

 more thickly granular, without distinct keels, but lobate on 

 the upper surface. 



Stermtes smooth and shining, the last beset posteriorly 

 with coarse sharp granules. 



Tail excavated above, the first three segments coarsely and
