but the form of the abdomen will serve to distinguish it from any of those belonging 
to this group. The abdomen is pubescent, and also set with short, stout, black spines. 
The central posterior eyes are larger and wider apart than the anterior centrals. 
8. Wixia sicula, sp.n. (Tab. XLVI. figg. 8, 8a, ¢.) 
Type, ¢, in coll. Godman & Salvin. Total length 5 millim. 
The general characters of this species are given in the generic diagnosis. It is very closely allied to W. clivosa, 
but differs from it mainly in the form of the clavis of the palpal bulb. The abdomen has a pair of coniform 
tubercles between the anterior shoulders, and a pair of white spots, transversely situated, midway between 
the spinners and the genital rima; it is clothed with long coarse hairs. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
PARAWIXIA, gen. nov. 
Type Epeira destricta, O. P.-Cambr. Guatemala. 
3. Coxa i. with a hook and femur ii. with a groove. A tubercle above coxa i. at the base. Coxa and femur, 
of pedipalp with a coniform spur and chitinous ridge respectively. Tibia ii. incrassate, armed with a 
row of five or six long spines beneath, with a double series of 5-6 stout specialized spines on the inner 
side, the spines of the posterior series finer than those of the anterior series, arranged irregularly in pairs. 
Femora ii. with a single series of 8 long erect spines; i. with a series of 5, and iii. and iv. each with a 
series of 5 or 6, spines beneath. Patella of pedipalp. bearing a single apical spine. Tarsal sheath with 
a large lamelliform bifid uncus at its base. Lateral eye-groups projecting forwards on a very distinct 
tubercle, well in advance of the anterior margin of the base of the mandible ; central anterior eyes also 
very prominent. Posterior row of eyes recurved. Anterior row of eyes distinctly recurved, the centrals 
being much nearer the margin of the clypeus than the laterals. Quadrangle narrower behind, posterior 
centrals much smaller. Trochanter iv., in the type, without spines; in other species with one or two. 
9. Posterior central eyes half a diameter apart, nearly equal to or slightly smaller than the anterior centrals, 
which are almost one diameter apart. Central quadrangle distinctly narrower behind, not longer than 
broad. Posterior row distinctly recurved; laterals one-half a diameter of the posterior lateral apart, 
which is smaller than the anterior lateral. The lateral pair separated from the posterior centrals by a 
space equalling two and a half times that occupied by the latter. Anterior row straight or slightly 
recurved, the centrals being slightly nearer the margin of the clypeus than the laterals. (In the males 
the rows are more recurved and the eye-groups closer together ; and the anterior lateral eyes are set on a 
low rounded tubercle.) Lower margin of fang-groove with 3 teeth, upper with 4. Legs clothed with 
numerous spines. Femora i. and ii. with two irregular series of short spines, iii, and iv. more or less 
irregularly spinose. Protarsi i.—iv. (in both sexes) with stout spines beneath, i. shorter than tibia and 
patella. Carapace not raised or convex behind the eyes. Sternum slightly longer than broad. Colulus 
present. Vulva having the scapus, atriolum, and lateral sclerites entirely fused together. Abdomen 
oval, but with more or less numerous shoulder, lateral, and apical tubercles. 
The species known to me may be distinguished as follows :— 
Males. 
a, Trochanter iv. devoid of spines. Uncus of tarsal sheath of palpus 
deeply bifid. Clavis of palpal bulb squarely truncate apically, 
not bifid or prolonged into a straight or curved point . . . destricta, O. P.-Cambr. 
b. Trochanter iv. with one or two spines. Uncus of tarsal sheath 
not bifid. Clavis of palpal bulb bifid, or prolonged into a 
narrowed and pointed termination.
