ONOCOLUS.—METATOBIAS. 161 
The vulva of the female, and the palpus of the male, will be found figured on the 
Plate. Several males and females occur in our collection. and the tibial spurs of the 
palpi of the former are identical with the figure given by Keyserling, referred to above. 
There is no reasonable doubt, failing an examination of the type in the Warsaw 
University, that these examples are identical with Keyserling’s species. 
TOBIAS. 
Tobias, E. Simon, Hist. Nat. Araign. (2) i. p. 1053 (1895). 
— Type Stephanopis camelinus, O. P.-Cambr. Amazons. 
Characters as in Onocolus, except that the carapace and body are more convex, the posterior row of eyes is 
procurved, and the ocular area is not produced conically behind the anterior lateral eyes. Colulus absent 
in both sexes. 
Three or four species referable to this genus are known, all of them from Tropical 
America. The species, 7. rugosus (Tacz.), to which I refer the males and females 
from Central America, appears to have a very wide range, extending all across the 
continent from Peru to the Atlantic.

(METATOBIAS, gen. nov. 
Type M. stelloides (Walck.). Tortola, West Indies. 
The type of Metatobias is the spider described by Keyserling as Stephanopis stelloides (Walck.). It can be 
distinguished from the genus Tobias by the spinigerous tubercles on femora i. and ii. (as also in Paratobias) ; 
and also by the stout spines on the apex of these femora, as well as by the fact that the patelle i. and ii. 
are carinate on each side. It may be separated from Paratobias by the spines on the apex of its femora 
i. and il. 
Tibie i. and ii. are incrassate, with a pair of deep depressions on each side towards the base. Tibiee i. and ii. 
with 2—2—2, protarsi i. and ii. with 2—2—2 spines beneath, but no laterals. 
Tarsi short and incrassate. Colulus absent. 
The occurrence of this spider in the West Indies points to the high probability that 
other examples of the genus are to be found in Central America. Its characters there- 
fore are diagnosed under a new generic name, because S. stelloides, Walck., does not 
belong to Stephanopis, O. P.-Cambr. [Ann. & Mag. Nat. Hist. (4) iii. p. 60 (1869) |, 
the type of which is S. altifrons, from 8. Australia. The details of structure are 
figured on Tab. XI. figg. 1, la-d (¢). 
I strongly suspect that the greater part of Nicolet’s Chilian species belong to the 
same genus. ‘This conclusion may, of course, have to be reversed eventually. |
