TIBELLUS. 
Tibellus, E. Simon, Araign. Fr. ii. p. 307 (1875). 
Type 7’. oblongus (Walck.). Europe. 
Carapace much longer than broad. Posterior row of eyes very strongly recurved. Posterior centrals much 
closer to each other than to the laterals, these with the anterior centrals forming an isolated transverse 
ovalgroup. Lateral anteriors equidistant from anterior and posterior centrals. Central quadrangle much 
longer than broad, only slightly narrower in front. Clypeus as high as the length of the central 
quadrangle. Protarsi and tarsi scopulate beneath. Coxe iv. closely situate. Legs iii. much shorter 
than iv.

Type, 2 (immature), in coll. Godman & Salvin. Total length 6 millim. 
Hab. Mexico, Amula (H. H. Smith). 
Subfam. MZISUMENINA. 
Mandibles without teeth on the margins of the fang-groove. Tarsi more or less cylindrical, not compressed, 
nor furnished with claw-tufts or spatuliform hairs, only with very slight tufts of simple hairs, Colulus 
present, but very minute. Tarsi i. and ii. not scopulate beneath. Legs iii. and iv. shorter, as a rule 
much shorter, than i. and ii. 
The following Table includes the more readily observed characters differentiating the 
genera of this subfamily :— 
AA. Legs i. and ii. entirely devoid of spines, except beneath the tibia 
and protarsi. Protarsi i. and ii. with from 6-10 pairs of spines 
beneath, but no lateral spines, except occasionally a single one. 
I. Ocular area exhibiting a more or less distinct angular prominence 
projecting from between the lateral eyes on each side. 
A. Central quadrangle longer than broad, not narrower in front. ([Prstius, E. Sim.] 
B. Central quadrangle broader than long, narrower in front. 
a. Lateral angle much more prominent, apex acute. Lateral 
anterior eyes not larger than central anteriors. Clypeus 
higher, equal to four diameters of an anterior central eye. 
(Central anteriors much nearer to each other than to the 
laterals.) 2. 0. 0. ee ee ee eee ee) e)6THOMISUS, Walck. 
b. Lateral angle much less prominent, apex obtuse. Lateral 
anterior eyes distinctly larger than central anteriors.
