264 ARANEIDEA. 
slightly emarginate in the centre of the posterior margin, with a pair of dark, narrow, oblique, anteriorly 
convergent, slit-like orifices towards the anterior margin of the area. Patella and tibia of palpus short, 
subequal, not longer than broad; tibia with a short, stout, curved, blunt spur at the middle of the outer 
anterior margin. Bulb broad, simple, slightly bilobate anteriorly, with, at its apex, a short, stout, sharp, 
conical, black spur (or spine). Mandibles much developed, the basal segment very long, with a stout 
spur at its apex above and a large, long, curved tooth or spur further down on the lower side, and also 
two smaller sbarp teeth close together, about a diameter of the anterior one apart, at the inner basal 
angle, to meet the point of the long, sinuous, slender fang (or apical segment). 
Hab. Guatemaa (Sarg). 
The female of this species resembles M. bicavatus in coloration and general appear- 
ance, except that it has no white central or marginal band on the carapace, and the 
ventral area, instead of being pale unicolorous, has a broad black central band. 
5. Metaphidippus pernix, sp.n. (M. feliz, Tab. XXIII. figg. 10, 10a, b, ¢ .) 
Type, d, in coll. Godman & Salvin. Total length 4°5 millim. 
Carapace red-brown, with a white band along the sides of the cephalic area beneath the lateral eyes, extending 
also on to the thorax. Abdomen ochreous-brown, clothed with iridescent scales; margin with a band of 
white hairs, unbroken in front and extending to the spinners. Legs red-brown, the tarsi and protarsi 
paler. Mandibles much developed, basal segment with a conspicuous cusp at the apex above, a very large 
tooth a little further down on the lower side, and two smaller teeth near the base; fang very long, 
abruptly curved at the base, sinuous and sharply curved at the apex. Bulb of palpus not projecting 
beyond the tibia; tibial spur very short, sharp, and slightly curved; apical spine forming an almost 
complete circle within the extreme apex of the tarsal sheath. The three spines on the inner side of 
tibia i. extend just beyond the middle of the segment. 
Hab. GUATEMALA (Sarg). 
6. Metaphidippus dentiger, sp.n. (Tab. XXIII. figg. 11, lla, 3, 3.) 
Type, ¢, in coll. Godman & Salvin. Total length 4-5 millim. 
Carapace red-brown or black, with a marginal band of white hairs encircling the cephalic and thoracic area. 
Abdomen red-brown, with a white marginal band, clothed with iridescent scales; ventral area brown. 
Legs unicolorous brown, the tarsi paler. Tibia i. with paired spines extending just beyond the middle. 
Mandibles much developed, with the usual three teeth—a large one towards the apex and two others, 
very small and adjacent, towards the base; fang very long, sinuous. Palpal bulb broad and somewhat 
compressed ; apical spine very short, stout, and curved ; tibial spur a little longer than the segment, 
curved, stout, bluntly pointed. 
Hab. Guatemaua (Sarg). 
7. Metaphidippus longipalpus, sp. n. (Tab. XXIII. figg. 12, 12 a-c, ¢.) 
Type, d, in coll. Godman & Salvin. Total length 7 millim. 
Carapace brown or black, with iridescent scales (these, however, very much obliterated) ; with a broad marginal 
band of white hairs; no median lateral band. Abdomen brown, with a marginal white band, broken up 
into white spots behind, with a broad dark band on each side more or less broken up into four square dark 
spots by white transverse spots; the dorsal area densely clothed with iridescent green scales ; ventral area 
brown. Legs dark brown, unicolorous, mottled with white hairs, with a conspicuous spot of white scales 
on the apex of the femur and base of tibie i. and ii. above. Palpus very long (as compared with that 
of others of the group); tibia and patella about equal in length, three or four times longer than broad ;
