TINUS.—ENNA. 311 
el and very deeply emarginate just behind it, then narrowed to the apex. Ventral area unicolorous 
yellow. 
Palpus of male :—Tibia only slightly longer than the patella, without any upper branch to the tibial spur. 
Tibial spur broad, pointed, concave, with a small recurved barb on the upper margin. Outer lobe of bulb 
narrow, bluntly pointed at the apex. Central portion of bulb consisting of a series (five or six) of pale disc- 
like lobes, the outermost very elongate and extending forward ; a stout spine (or stylum), spirally curled, 
lies at the apex of the bulb within the tarsal cavity. 
Vulva of female consisting of two large, broad, adjacent lobes, having a small, central, anterior, oval, concave, 
tongue-like process, but no large concavity.

2. Tinus tibialis, sp. n. (Tab. XXX. figg. 10, 10a, 6, ¢ ; 11, ?.) 
Type ¢, gynetype 2, in coll. Godman & Salvin. Total length, g 11, 2 15 millim. 
The coloration and general characters, so far as one can judge from the two examples received, are almost 
precisely similar to those of 7. nigrinus; but the vulva and palpus of the male are very different in form. 
Palpus of male:—Similar in general character to that of 7. niyrinus, but the tibia is three or four times 
longer than the patella, and has a long, slender, curved upper branch to the tibial spur; the lower branch 
is concave and pointed at the apex, but has not a recurved barb. The outer lobe of the bulb is much 
broader than in 7’. nigrinus, being broadly rounded at the apex. The central series of discs are similar, 
but not so numercus (3 or 4) as in the last-mentioned species ; the spiral spine is very similar in form. 
Vulva of female consisting of two large lobes, in contact behind, but divided anteriorly by a deep broad 
concavity, in the centre of which lies a convex, rounded, lid-like process, divided backward, connected with 
an internal, central, pale, sinuous process, lying on the floor of the cavity.

3. Tinus minutus, sp.n. (Tab. XXX. fig. 12, ¢.) 
Type, 2, in coll. Godman & Salvin. Total length 7 millim. 
Carapace and legs yellow, the former darker, with a narrow central and a single lateral paler band on each 
side. Abdomen coloured as in the other species of the genus. 
Vulva similar in general character to that of T. nigrinus and 1’. tebials, but with a narrow concavity in the 
anterior half, in the centre of which lies a small, transverse, black, convex, chitinous piece.

Type £. veloa, O. P.-Cambridge. Central America. 
Anterior row of eyes straight or slightly recurved; centrals larger, scarcely one-half of a diameter apart, 
almost in contact with the laterals; posterior centrals at least one and a half diameters apart, rather over 
half a diameter from the laterals. Clypeus as high as one and a half diameters of an anterior central eye. 
Both margins of the fang-groove tridentate, the teeth on the lower one equal and equidistant. Tibiee i. and ii. 
with 2—2—2 spines beneath and a pair of small apical spines, besides laterals on both sides. Protarsi i. 
and ii. with 2—2—2 spines beneath, besides laterals ; protarsi of all four pairs of legs with a single, small, 
central, apical spine beneath. Legs 4 (1, 2), 3. Tarsi not flexible,
