Mr. R. I. Pocock on Neotropical Scorpions. 79 
Pectines with 8 or 9 teeth. 
Measurements in millimetres.—Total length 62, of carapace 
9, of tail 37; width of first segment 5, length 3°5; width of 
fifth and of vesicle 3°5, length of fifth 8°8. 
Two female specimens in the Museum collection ticketed 
“©? China,” a locality which is without doubt erroneous. 
This species has an interesting history. On p. 232 of the 
Act. Mus. vol. iv., Gervais, in connexion with his description 
of Broteas maurus, refers to a scorpion in the British Museum 
eollection which is ticketed China and is very near to his 
maurus, ‘This scorpion, there can be little doubt, is the one 
that I have here described and dedicated to the distinguished 
French zoologist. One of the specimens bears an old label 
upon which is written ‘Scorpio subnitens, Gervais, MN., 
?China.” ‘he scorpion figured by Prof. Lankester in the 
Trans. Zool. Soc. vol. xi. pl. Ixxx., as Broteas subnitens, 
Gervais, is Teuthraustes atramentartus of Simon. 
This new form Gervaisii may be at once recognized from 
the Broteas that I identify as B. Herbstit by having the 
lower surface of the first caudal segment smooth, polished, 
and with ovsolete median keels. Of the last-named form the 
British Museum has upwards of a dozen specimens of varying 
age and sex from different parts of British Guiana. Upon 
the identity of Herbstit of Thorell, however, there seems to 
me to be some doubt. ‘The name was applied by Thorell to 
the scorpion described as maurus of Linnzus by De Geer and 
later authors. But it seems to me to be very doubtful if all 
these authors have described the same species as maurus ; 
for instance, Herbst’s figure of maurus seems to me to repre- 
sent a totally different form. 
C. Koch, however, in 1838 described as the type of Broteas 
a species he named maurus, which came from Cayenne 
(French Guiana). It is highly probable therefore that this 
species of Koch’s is identical with my examples from british 
Guiana, and for this reason I identify these as Bb. Herbstit, 
being unable to ascertain the characters of B. maurus of De 
Geer, ¢. e. the true Herbst’i. Why Mons. Simon should 
assert that B. Herbstid comes principally from La Plata, 
seeing that both C. Koch and Gervais especially mention 
Cayenne and Guiana as localities, [ am unable to surmise. 
According to Simon’s description (Ann. Soc. Ent. Fr. 1877, 
p- 240) his #erdstiz has the anterior caudal segments smooth 
and punctured above between the keels, which are almost 
absent on the first. If, however, in this description for dessus 
we read dessous, it would apply well to my B. Gervaisit ; but 
as the description stands it 1s not applicable either to my 
rk
