two new Genera of Scorpions. 47 
differs in fact in the form of the sternum. Of all the genera 
of Buthide it certainly comes nearest to Butheolus of Simon 
(Orthodactylus, Karsch); but although the sternum in 
Butheolus is more pentagonal (? always) than in the others, 
it is not so markedly wide as in Leterocharmus. 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, Heterocharmus be compared with the known 
genera of other families, the only one with which it presents 
any affinity is Charmus of Karsch, a genus which this author 
referred to the Iurini. 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 Zurus, 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 Charmus 
and Heterocharmus. 
Hleterocharmus 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 band, manus infuscate; legs fuscous, with testaceous 
joints. 
Cephalothorax 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. 
Lergites granular, more coarsely but less closely so than is 
the cephalothorax, the first without the median keel, the last 
more thickly granular, without distinct keels, but lobate on 
the upper surface. 
Sternites smooth and shining, the last beset posteriorly 
with coarse sharp granules. 
Tail excavated above, the first three segments coarsely and
