170 ARANEIDEA. 
of great length, about 14 times the length of the joint; the radial joint is slightly clavate, prominent 
beneath the fore extremity, and furnished with long bristles, those near the base on the upperside being 
almost spines, at its extremity on the outer side is a short but tolerably strong apophysis, whose hooked, 
obtuse, and somewhat bifid point is directed backwards. Palpal organs simple, consisting of a convex 
bulb with two corneous projections beneath their fore extremity. 
Mawille long and strong, straight, enlarged at their extremity, where they are obliquely truncated on the 
inner side, and furnished there densely with hairs; inner margin greatly excavated, forming a kind of 
‘domed niche over the labium. They are a little paler in colour than the falces. 
Labium half the length of the maxille, rather narrower at the apex than at the base, a little way above which 
the margins are sharply indented; apex strongly emarginate, and furnished with a row of converging 
black bristles. It is similar to the maxille in colour. 
Sternum heart-shaped, ending posteriorly in an obtuse rounded point between the coxe of the fourth pair of 
legs. Colour like that of the legs. 
Abdomen narrow-oval, of a dull luteous-yellow colour, clothed thinly with pale hairs and a few dark bristles ; 
the spinners are tolerably long, those of the inferior pair shorter but stronger than the superior, and 
of an elongate subconical form. Colulus short, broad, and truncate. 
Hab. Mexico, Teapa in Tabasco (4. H. Smith). 
TEMECULA *, gen. nov. (Dictynide). 
Allied to Amaurobius, C. Koch, but differs notably in the relative size and position of the eyes, as well as in 
some other points of structure. 
Cephalothorax oval, much longer than broad ; caput broad, quadrate, with the fore corners rounded off; sides 
parallel; profile even, gradually sloping on thorax, rounded or convex on caput. Normal indentations 
of thorax very slight. 
Eyes in two transverse very nearly straight lines, occupying the greater part of the width of the caput, the 
posterior row longest ; unequal in size; the fore-laterals much the largest, the fore-centrals much the 
smallest, the difference between them being very considerable. The latter much nearer together than to 
the former, and a similar position also between the eyes of the posterior row. The interval between,the 
eyes of each lateral pair is equal to the diameter of the hind-lateral eye. 
Legs moderate (subequal) in length and strength; 1, 4, 2, 3, furnished sparingly with spines on those of the 
Ist, 2nd, and 4th pairs, chiefly beneath the tibize of the 1st pair. 
Mazille strong, slightly inclined towards the labium, broader at the extremities than at the middle, where 
they are broadly but not strongly impressed in a transverse direction ; extremities rounded. 
Labium nearly double of its width in length, rather more than half that of the maxille, oblong, rounded at 
the apex. 
Sternum broad-oval, rather truncate at the fore extremity. 
The four exterior spinners moderate and equal in length, the anterior pair strongest, those of the super- 
numerary pair distinctly separated from each other. 
Temecula mexicana, sp. n. 
Adult male, length 23 lines. 
Cephalothorax dark brown, the normal grooves and indentations slightly darkest; furnished thinly with coarse 
pale hairs ; height of the clypeus equal to the diameter of one of the fore-lateral eyes. 
Legs dull yellowish-brown, femora black-brown ; well furnished with hairs ; spines few and slender, mostly 
beneath the femora of the first pair. 
Palpi yellowish-brown ; humeral joint blackish-brown, not very long. Cubital joint very short above, rather 
towards the inner side produced into a strong, subconical, pointed projection, which is equal to the joint in 
length, and directed inwards; radial joint also very short, but much produced on the inner side, with a 
strong tuft of black bristly curved hairs on the outer side ; digital joint large, with a strong obtusely pointed
