MODISIMUS.—MICROMERYS. 149 
Modisimus inornatus, sp. n. 
Adult female, length 1} line. 
This spider is nearly allied to both M. maculatipes and M. putus. It is, however, rather larger, and differs in 
colours and other respects. The cephalothorax is very broad, and very deeply excavated or indented 
behind at the insertion of the abdominal pedicle. The thoracic indentations are also very strong. The 
eyes are nearly equal in size and in the same general position, but the hind-centrals are rather nearer 
together than in the other two species mentioned, making the intervals between the eyes of the hinder 
row more nearly equal. The four central eyes form very nearly a square whose posterior side is slightly 
shortest. The tubercles on which the eyes are seated are very strong and of a deep brown colour. The 
cephalothorax is a dull brownish-olive tinged brown, with a broad yellow-brown longitudinal central band, 
which also includes the eminence on the caput. 
The legs are very long, slender, similar in colour to the cephalothorax, and near the extremity of the femora 
and tibie is a largish, ill-defined, dull yellowish-brown annulus, the space between the annulus and the 
end of the joint being pale whitish-yellow ; the genua are also dull yellowish-brown. ‘The tarsi are multi- 
articulate like those of the other’species of the genus. 
The palpi are very short and slender, devoid of a terminal claw, and of a dull yellowish-brown hue. 
The falces are similar to the legs in colour. 
The mazxille and labium are more suffused with dusky brown. 
The sternum is exceedingly convex, furnished with a few long, prominent, bristly hairs, very broadly truncated 
behind; its colour is dusky yellow-brown, with a tolerably well-defined oval patch along the middle, and 
the lateral margins of a brownish-yellow hue (like the legs). 
The abdomen is of a dull bluish sea-green colour, with two curved longitudinal lines of dark brownish-black 
spots in pairs along the middle of the upperside, the convexity of the curves directed outwards, and the 
space between them paler than the rest; besides these, there are numerous other dark spots on the sides 
tinged with green. The genital aperture is of a different form from that of the other two species, and 
connected with it immediately behind is a prominent globular pale process, which at first sight looks like a 
fortuitous accretion, but on close examination it appears to be a portion of the normal structure of that 
part. The spinners are small, short, compact, and of a blackish-brown colour,

“ Found in a thick web forming a tent about 4 inches long and 24 wide, between 
the sticks of a paling, and protected by leaves, in a dark, shady, damp cacao-orchard.” 
MICROMERYS, Simon. 
Micromerys delicatus, sp. n. 
Adult male, length 14 line. 
Cephalothorax round, with the clypeus prominent and drawn out to an extent equal to half that from the line 
of the eyes to the hinder extremity of the thorax, and somewhat squarely truncate at its extremity. The 
normal grooves and indentations are scarcely perceptible. The colour of the cephalothorax is pale yellow. 
Eyes six, in two triangular groups of three each in a transverse line, occupying the whole width of the caput, 
those of each group on a strongish black tubercular prominence and nearly contiguous to each other; 
the interval between the interior eyes of the two groups is equal to three (if not more) diameters; these 
eyes are the apices of the two triangles formed by each three eyes respectively. The anterior eye (looked 
at from above and behind) of each group is the largest. ; 
Legs excessively long and slender, 1, 2, 4, 3, furnished only with very short fine hairs. Colour similar to that 
of the cephalothorax. 
Palpi long, very strong, similar to the legs in colour; the humeral, cubital, and radial joints greatly incras- 
sated, the latter very glossy and of an almost globular form on the upperside, and furnished at the fore 
extremity with a few long, very slender hairs; digital joint small and short. Palpal organs greatly 
developed, consisting of a large, glossy, obtuse-oval, whitish bulb directed inwards, its posterior
