148 ARANEIDEA. 
is of distinctive form and placed much nearer the middle of the underside than usual, almost like that of 
Mesopneustes, Cambr. (p. 126, anted). 
Hab. Mexico. Teapa in Tabasco (H. H. Smith). 
MODISIMUS, Simon. 
Modisimus maculatipes, sp. n. 
Adult female, length 1 line. 
Cephalothorax nearly round, broadest behind ; the middle of the fore part of the caput is raised into a strong 
prominence bearing the eyes at its summit. The normal lateral indentations are slight, that between 
the caput and thorax strong. It is of a dull greenish-yellow colour, with dusky ill-defined converging 
lines on the sides; two (parallel) longitudinal, not sharply defined, violet-coloured lines run backwards 
from the hinder side of the prominence on the caput. 
Eyes six, of considerable size, rather closely grouped in a largish quadrangle round and near the summit of 
the caput, seated on strongish black tubercles ; they are in two transverse rows, the anterior row of two 
eyes (the largest) being a little shorter than the posterior row, which is slightly curved, the convexity of 
the curve directed forwards. The interval between the hind-central pair is greater than that between 
each and the hind-lateral eye next to it, being about a diameter’s extent, each hind-lateral being nearly 
contiguous to the hind-central on its side. 
Legs excessively long and slender, furnished only with very short fine hairs ; colour pale yellowish, with a few 
dark brown or blackish spots on the tibie, genua, and femora; tarsi multiarticulate, each articulation 
furnished with a ring of hairs. 
Palpi very short, slender, like the legs in colour, but with the extremity of the digital joints blackish. 
Falces short, not very strong, straight, and with a dusky blackish-brown, slightly oblique stripe in 
front. 
Mazxille and labiwm normal. 
Sternum large, very convex, round behind, broadly hollow-truncate in front. Colour dusky brown, speckled 
with yellowish points, and with a narrow yellow margin. 
Abdomen short but globular above, and pointed at the spinners ; it is of a pale bluish sea-green colour, marked 
near the middle of the upperside with two pairs, pretty close together, of deep dull greenish spots, the 
anterior pair largest ; on the underside also, in front of the spinners, is a single dark spot with a lighter 
greenish longitudinal line between it and the genital aperture, which is on a dark spot, not very 
prominent, but of characteristic form. About twelve or fourteen eggs loosely connected with silken 
web accompanied this spider. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
“Found with egg-case in a very small, thick, irregular web under a leaf.” 
Modisimus putus, sp. n. 
Adult female, length slightly over 1 line. 
‘This species closely resembles M/. maculatipes in all essential characters, but is paler; the general colour is 
dull luteous yellow, tinged with greenish on the thorax and abdomen; on the abdomen, besides 
the two pairs of dark spots at the middle of the upperside, there are some indistinct whitish spots on each 
side disposed in two somewhat slightly oblique lines, and two longitudinal parallel lines following the 
dark spots. There is also no longitudinal central marking on the cephalothorax, or if there is it is almost 
obsolete, and the only visible spot on each leg is a very small indistinct one towards the fore extremity 
of the tibie. The genital aperture is also different in form, being larger and (looked at in profile) much 
more prominent. The false joints, or articulations, of the tarsi seem also to be more distinct,
