Norz.—I am not sufficiently well acquainted with the characters of M. centralis, M. dubitabilis, M. hondu- 
rensis, or M. vegetus (Peckh.) to enable me to insert them in the Table; they probably belong, however, 
to this group of species, and a figure of the vulva of each of the first three of these will be found on our Plates. 
M. retiarius, M. nubilus, and M. capitatus (Hentz), which also belong to this genus, are unknown to me.

Type, d, in coll. Godman & Salvin. Total length 6 millim. 
Dried example. Carapace deep purple-brown, the cephalic area clothed with green and white scales, having 
also a narrow marginal band of white scales. Abdomen brown, with a central longitudinal dorsal band 
of green iridescent scales and a double row of four spots of white scales, and a broken marginal band of 
the same, the two arms of the band not meeting in front; sides and ventral area brown, thinly clothed 
with fine ochreous hairs. Femora i. and ii., apex of patelle i. and ii., tibia i., apex of protarsus 1., and 
the apices of all the other segments of the legs ii., iii., and iv. (except the tarsi) brown, the rest of the 
legs yellow ; the apices of the femora and the bases of the tibie and patelle i. and ii. strongly, of i. and 
iv. slightly, clothed with white scales. Sternum, maxille, and labium, the coxe and trochanters of leg i., 
and the mandibles deep brown.

than to the lateral posteriors. Mandibles very long, the basal segment longer than the carapace, with a
