result of shrinkage of the underparts from the action of the spirit in which it was preserved). It is of a 
luteous colour, marked, but not regularly, with some whitish cretaceous-looking markings on the upper- 
side, which also has three transverse rows, each of four dark black-red spots,—the first row is on the fore 
margin, and the other two rows divide the upper surface; the space, however, between these rows is 
greater than that between each and the extremity nearest to it. The posterior margin is marked by a 
black transverse narrow, but very distinct, border. The sides are margined with blackish-brown. 
Hab. Guaremata, San Juan Chamelco in Vera Paz (Sarg); Panama, Bugaba 
(Champion). 
An immature male only from Bugaba. 
Synema, affinitata, sp. n. 
Adult male, length 14 lines; female, length 3 lines. 
The cephalothorax of the male is of a red-brown hue, bordered with a deep blackish-red-brown marginal stripe 
—a mere line at the caput, but gradually becoming much broader at the thorax; the sides and caput are 
also marked with paler converging stripes corresponding with the normal indentations. The surface is 
thinly granulose, and thickly covered with very minute shallow punctures, giving it an appearance of 
shagreen. 
The eyes are normal in relative size and position ; those of the fore central pair are, if anything, very slightly 
further apart than each is from the adjacent lateral eye, while those of the hinder row are equidistant 
from each other. The four central eyes form very nearly a square, three sides being equal, but the 
posterior side is slightly longer than the rest. The height of the clypeus is less than half that of the 
facial space. 
The legs, 2, 1, 4, 3, are moderately strong. Those of the two anterior pairs are, as usual, much the longest, 
and nearly of equal length, and have the femora, genua, and tibiae of a rich blackish-red-brown colour, the 
metatarsi and tarsi being of a brownish-yellow hue. They are furnished fairly with long, tolerably strong, 
spines of different lengths. The femora of the first and second pairs are slightly granulose. The two 
posterior pairs are of a pale brownish-yellow colour, and also spinose. 
The falces are short, strong, subconical, vertical, and like the cephalothorax in colour. 
The palpi are short, similar in colour to the tarsi and metatarsi of the anterior legs; the radial is rather shorter 
than the cubital joint, and has a long, strong, tapering black spine near its inner side in front, and its 
outer fore extremity is produced into a short, slightly curved, pointed, tapering, rather prominent apophysis. 
The digital joint is of moderate size, and the palpal organs, which are simple, appear to be encircled with 
a double-coiled spine. 
The maxille, labiwm, and sternum are normal in form and rather paler in colour than the cephalothorax. 
The abdomen is rather elongate-oval, flattish convex above, of a somewhat coriaceous texture, and covers the 
underparts like a shield. A few long, strong, prominent, spine-like bristles are placed at intervals round 
the anterior margin (but most of them are broken off in the only male example seen). The upperside is 
of a luteous colour, slightly mottled with whitish and bordered with a narrow whitish border. Each 
side of the fore half has a rather broad dusky submarginal band, and a transverse bar of the same hue, 
broken in the centre, runs across a little way behind the middle. The posterior extremity has a narrow 
black margin. 
The female is much larger than the male, and the sides of the cephalothorax are more broadly banded with a 
darker hue than the upper part. 
The height of the clypeus is very near equal to half that of the facial space; and there are some long strongish 
bristles, chiefly on the sides of the caput and along the lower margin of the clypeus. The legs are similar 
in colour to those of the male, excepting that they have a broad pale annulus on the hinder half of the 
tibie of the first and second pairs. 
The abdomen is large, the upper surface flattish, of a subpentagonal form ; the fore extremity and posterior 
angles much rounded. The upperside is yellow-brown, with a broad marginal cream-white band and two 
spots of the same colour in a transverse line across the middle. The marginal band is broadest behind,
