162 ARANEIDEA. 
PARATOBIAS, gen. nov. 
Type P. championi, sp. n. Central America. 
Similar to Metatubias, but with the central posterior eyes slightly smaller than the laterals, and much closer to 
each other than to the laterals. Femora i. and ii. with dorsal tubercles, but no apical spurs. Tibi i. 
and ii. not incrassate, with 2—2—2—2 spines; protarsi i. and ii. with 2—2—2—2 spines beneath, no 
laterals. ‘arsi short and incrassate. Colulus absent. 
This genus is based on a single species from the State of Panama. 
1. Paratobias championi, sp.n. (Tab. XI. figg. 2, 2a-e, 2.) 
Type, @, in coll. Godman. & Salvin. Total length 6 millim. 
Colour piceous ; body and legs clothed with short white pubescence ; abdomen with, in addition, numerous 
bacilliform hairs. | . 
Carapace longer than broad, narrowed at the ocular area. The latter prominent, raised, developed into a conical 
horn behind the lateral anterior eyes, leaving a deep cleft between. Posterior row of eyes recurved, the 
posterior margin of the laterals falling just behind the centre of the centrals. Centrals smaller and closer 
to each other, one and a half diameters apart, than to the laterals, two diameters from them. Anterior 
row recurved, centrals very minute, further from each other than from the laterals, which are very much 
larger. Clypeus equal to more than four diameters of an anterior central eye. 
Femora i. and ii. incrassate behind, bearing two pair of spinigerous tubercles on the dorsal surface and two 
along the anterior margin, but without apical spurs. Patella and tibia i. and ii. compressed, and grooved 
above; protarsi i. and ii. compressed above but not grooved. 
Tarsi i. and ii. short and incrassate. 
Vulva consisting of a large circular-oval concave chitinous disc, shghtly rebordered along the circumference 
and more prominent in the centre of the posterior margin. 
Hab. Panama, Bugaba (Champion). 
[POTH AUS. 
Potheus, Thorell, Descr. Cat. Spid. Burma, p. 275 (1895). 
Type P. armatus, Thor., in Mus. Brit. Burmah. 
The characters of a single immature female spider from Guatemala run so close to 
those of the type of Pothwus that I am unable to separate them generically. The 
occurrence of this form is recorded as an interesting fact, though the immaturity of 
the specimen precludes one from describing the species. | 
[STEPH ANOPOIDES. 
Stephanopoides, Keyserling, Spinn. Amer., Later. p. 166 (1880). 
Type S. brasiliana, Keys. Brazil. 
Although no species of Stephanopoides has occurred as yet in Central America, it is 
necessary to insert figures of its distinguishing characters [‘Tab. XT. figg. 3, 3a (3 )]. 
The spider referred to it in Vol. I. of this subject belongs to the following genus, 
Parastephanops. |
