METEPEIRA. 459 
the apical half, and a series of one or two (or more) smaller bristles beneath. Palpal organs similar in 
general character to those of the other species of the special group, exhibiting a double-bladed reap-hook- 
like process (unca) on the underside of the bulb, with a partially concealed embolus lying under the 
apices. of the blades; apically there is a conspicuous, rounded, elongate lobe, deeply indentate on its 
outer margin, and exhibiting at this point a cluster of sharp black denticules. Close above this lobe and 
basally lies a thin yellow lamina, with three serrations on one side and one on the other, and adjacent to 
its base a second small oval triangular sclerite (lamina 2). The form of the unca is characteristic: in 
the present species the shaft is almost as long as the blade, which takes a much less wide curve than 
in M. uncata, and is stouter, The shape and position of lamina 2 of the bulb serves also to separate 
M. labyrinthea from M. spinipes.

Although M. labyrinthea is one of the commonest and best known of Hentz’s 
species, American arachnologists have never identified it with any certainty. They 
have not yet given an accurate description of the species, nor are their figures 
sufficiently detailed for purposes of identification. The same remarks apply also to 
Keyserling’s work 5, Fortunately, however, a male and a female example from North 
Carolina, whence the type was obtained, are before me, and they are identical with 
those from Central America in our collection. _McCook’s figures (loc. cit. t. 7. 
figg. 10, 11) seem to agree better with I. spinipes; and his fig. 12 may represent the 
true MM. labyrinthea or M. incrassata. The example referred to M. labyrinthea by 
Simon, from St. Vincent, is an immature female, and is now before me. 
The very narrow scapus of the vulva in the female, the form of the unca in the 
male, and the comparative shortness of the legs and scarcity of spines on femora i. 
and li. in both sexes, are the characters to be noted.

Type, 3d, in coll, Godman & Salvin. Total length 5 millim. 
¢. Carapace brown, caput paler; mandibles and sternum brown, the latter with a faint pale central line 
behind. Legs coloured as in M. labyrinthea. Abdomen white, mottled with brown, with the usual 
central folium, the six /\-shaped marks being very distinct. Femur i. spinulated as in M. labyrinthea, 
but with a long series of spines (12 or 13) on the outer side beneath ; femur ii, with a series of 6 or 7 
spines beneath. Palpal organs similar to those of M. labyrinthea, but the shaft of the unca is very long 
and slender, rather longer than the blade, which takes a much wider sweep and is more slender 
throughout. The same characters will serve to distinguish it from M. spinipes.
