surroundings; the labium is chiefly in Phrynichus 
strongly dilated at the basis. Unfortunately my material 
of Charontine is so limited (only 2 specimens, the one 
of which is very small, the other with a destroyed 
sternum) that I cannot undertake an investigation of 
its structure in this group. 
Simon states that Phrynichince and Tarantulince 
have 4 joints in the tarsus of 3 pairs of legs, while 5 
joints are found in Charontine. That is correct. But 
on closer examination of my 2 specimens of Charontince 
(1 Charon Hoeventi Karsch, 1 Charinus Australianus 
L. Koch) I have found, that the articulation between the 
2d and 3d joint in the tarsus is a little lesser developed 
than between the 3d and 4th or 4th and 5th joint. 
Examining a rather large material of several species of 
the genus Admetus I perceived, that the 2d joint 
always showed on the lateral sides and on the dorsal 
side a little from the apex a rather narrow, but very 
distinct, clear, transverse stripe (Tab. Il," fig. 15, a), in 
its site answering to the articulation between the 2d 
and 3d joint in Charontinæ, that is to say: a rudi- 
mentary articulation, in the last-mentioned group appearing 
as a developed articulation. I do not know from 
autopsy the very closely connected genus Tarantula, 
but I do not suppose, that it differs on that point from 
Admetus, and therefore I do not hesitate to admit this 
commencing articulation as a character for the sub- 
family. — No trace of a transverse division of the 2d 
joint of tarsus is found in Phrynichus nigrimanus C. 
Koch and Damon medius Hbst. 
If we add the new character to several of the older 
ones, we see that the classification of Simon: Charon- 
tinee, Phrynichine, Tarantulinc, is not natural, as 
the Ist sub-family is closer connected with the 3d than 
with the 2d family. I presume undivided hind tibiæ,
