METAPHIDIPPUS. 265 
bulb not basally produced over the tibia; apical spine slender, black, sharp, its point directed obliquely 
forward and inward; tibial spur short, sharp, curving slightly downward. Mandibles much developed, 
with a stout tooth (or cusp) on the lower side, about the middle, and a pair of small teeth more towards 
the base on the upperside; fang very long, sinuous and stout, a little rugulose at the base beneath. 
Hab. Panama, Bugaba (Champion). 
8. Metaphidippus globosus, sp.n. (Tab. XXIII. figg. 13, 13 a-c, 3.) 
Type, ¢, in coll. Godman & Salvin. Total length 4:5 millim. 
Carapace red-brown, clothed with iridescent scales. Abdomen brown, with a marginal white band and a 
paler central dorsal band clothed with iridescent scales, and a pair of lateral dark bands broken by four 
white spots, but not divided into separate squares, as in some other species of the genus; ventral area 
brown. Legs i. brown, the femur darker ; ii., iii., and iv. pale yellow, unicolorous. The paired spines 
beneath tibia i. reaching just beyond the middle of the segment. Mandibles somewhat enlarged, without 
any upper apical cusp, but with a large lower tooth near the apex and two smaller teeth nearer the base ; 
fang stout, long, sinuous. Bulb of palpus enlarged, globose; apical spine short and slightly curved ; 
tibial spur very large (as compared with that of other species of the genus), convex at the base, bluntly 
pointed and unguiculate at the apex.

9. Metaphidippus maxillosus, sp.n. (Tab. XXIII. figg. 14, 14 a-d, 3.) 
Type, ¢, in coll. Godman & Salvin. Total length 5:5 millim. 
Carapace black, clothed with scattered iridescent scales, without marginal bands, but with a white median 
Jateral band extending from beneath the small eyes almost to the posterior margin. Abdomen brown, 
clothed with iridescent scales, with a white marginal unbroken band; ventral area brown, broadly 
margined with pale yellow. Legs i. unicolorous brown, the femur darker; ii., iii., and iv. yellow, apical 
two-thirds, apex of patella, and base of tibia suffused with dark brown ; tibia i. spinose to the middle on 
the inner side and to just beyond it on the outer side. Carapace slightly inflate laterally, behind the 
posterior eyes. Sternum rather more than one-half longer than broad, not abruptly narrowed behind. 
Mandibles very much developed, elongate, with a stout tooth on the outer (lower) side towards the apex; a 
much smaller one towards the base, with two very minute teeth opposite it, to receive the point of the 
very elongate, slender, sinuous fang; the basal segments sweep outward, curve upward, and are widely 
divergent at the apex. Spine of palpal bulb not at the apex, but springing from the inner side at the 
tip, forming a bold spiraliform coil, its apex directed downward ; tibial spur long and slender. 
Hab. Mexico, Orizaba (1. H. Smith). 
10. Metaphidippus apicalis, sp. n. (Tab. XXIII. figg. 15, 15 a-d, 3; 16, 
16a, 2.) 
Type 3, gynetype 2, in coll. Godman & Salvin. Total length, ¢ 4:5, 2 5 millim. 
Carapace black, clothed with scattered iridescent scales, but without lateral white bands or a central cephalic 
white spot. Abdomen with a brown anterior dorsal spot, two lateral spots on each side, and an apical 
spot ; margined and the spots outlined with white, the central dorsal area clothed with pink iridescent 
scales. Legs brown, more or less clothed with white hairs; tibia i. with the usual 2—2—2 spines, but 
these are situated at the extreme apex of the segments. Palpal bulb somewhat enlarged at the base, 
with a short black apical spine slightly curved inward at the tip; tibial spur short, slender, abruptly 
hooked at the tip. 
Mandibles very much developed, with a large single lower tooth and two small upper ones ; fang elongate, stout, 
with a very low conical protuberance beneath in the basal half, abruptly narrowed about the middle. 
Female similar to the male, see Table and figures.
