5. HUMENOPHORINE : Loxomphalia, Sim.; Hysterocrates, 
Sim. (= Hysterocrates + Phoneyusa, Sim. (not Phoneyusa, 
Karsch) + Lycotharses, Thor.) ; Phoneyusa, Kargch 
(=almost certainly Pelinobius, Karsch) ; Humenophorus, 
Poc.; Citharischius, Poc.; Monocentropus, Poc.; Ano- 
ploscelus, Poe. 
Distribution. Vropical Africa from Sierra Leone and the 
Congo in the west to Abyssinia and the Zambesi in the east.

Zool. Soc. 1897, pp. 758-773, and 1899, pp. 841-845; Ann.

6. THERAPHOSINZ : containing a large number of genera, 
principally confined to America, south of, and including, 
the Sonoran area, with a few outlying forms in the 
Mediterranean, Indian, and Tropical African Regions. 
This subfamily will probably prove to be capable of finer 
subdivision. At present it contains a very heterogeneous 
assemblage of genera, many of which are based upon differ- 
ences in the size or position of the eyes, the divisional line 
of bristles on the tarsi, or other unsatisfactory characters. 
In the following pages I have made use of certain new 
features, namely, the nature of the hairs clothing the 
surfaces lying between the palpi and the legs of the first pair 
which are constant in both sexes, and for the males the 
method of folding of the protarsus of the first lee with 
reference to the tibial spurs. 
By these characters I find that the so-called genus Lastodora 
is divisible into several distinct genera, and that under 
Eurypelma have been included species belonging to widely 
divergent genera. ‘The name Lurynelma was affixed b 
Simon in 1892 to the species erroneously described by Koch 
as avicularia, Linn., and afterwards named rubropilosum by 
Ausserer. 1 am not aware whether this species is known to 
Simon; it is unknown to me: nor dol know that Ausserer’s 
specimens were specifically identical with those described by 
Koch. Koch, however, speaks of the first leg of the male 
as being furnished on the tibia “ mit einem dicken, haken- 
formig einwarts gekriimmten borstigen Sporn ”’—a feature 
which is characteristic of Avieularda or perhaps Acantho- 
scurrta, but not of Hurypelma as recognized by Ausserer in 
1871 and Simon in 1892. In 1864, however, Simon 
evidently intended to restrict the name Eurypelma to a section
