others, much smaller, in a transverse line at the posterior extremity, which is obtuse, and drops thence 
perpendicularly to the spinners. The middle one of these three prominences is rather the strongest ; it 
is clothed with whitish and other pubescence, reflecting greenish-golden tints in a strong light, and has a 
few slender prominent bristles on the upperside, which is of a dull greyish-yellow hue; from the sum- 
mit of each anterior prominence a black-brown dentated line runs to the outer posterior prominence, 
forming a strong curve whose convexity is directed inwards—the space included by these lines, as well as 
the whole front of the abdomen beyond the anterior prominences, is dark brown marked longitudinally 
with a somewhat obscure darker central line. The sides and hinder declivity are nearly concolorous with 
the upperside, and are marked with blackish-brown broken lines and markings. ‘The underside is of a 
leaden-black hue, with two white spots—one (the largest) near the middle, the other just in front of the 
spinners. Looked at in profile the hinder part of the abdomen (where the posterior prominences are 
placed) is rather elevated, so that the profile line is hollow, and gives the abdomen a slightly constricted 
appearance. 
Hab. Panama, Bugaba (Champion). 
This spider is allied to E. armata, but differs in the abdominal pattern and in the 
colours and markings of the legs, and also in the precise character of the armature of 
the coxal and exinguinal joints of the first and fourth pairs. The palpal organs also, 
though showing a great similarity of development, are not nearly so large, and differ in 
the form of the processes and in the much less size of the palpal bulb. 
Epeira destricta, sp. n. 
Adult male, length 43 lines. 
Cephalothorax round in the thoracic region, the sides of the caput converging rather strongly forwards. It is 
of a yellow-brown colour, clothed with grey hairs; the sides of the thorax, as well as several spots on the 
occiput, and some short diverging markings on the upper part of the thorax, dark yellow-brown. 
The eyes are in the usual three groups; the prominence of the central group is well produced forwards, the four 
central eyes forming a square whose posterior side is considerably the shortest—the eyes composing it are 
smaller than the anterior pair, and are separated by more than a diameter’s interval. The eyes of each 
lateral pair are placed a little obliquely and almost contiguous to each other on a strong tubercle. The 
fore central eyes are removed from the lower margin of the clypeus by no more than half a diameter, and 
from each other by a diameter’s interval. 
The falces are long, rather weak, inclined towards the sternum, hollow in profile both from in front and 
laterally, and of a pale yellowish colour. 
The legs are tolerably long, strong, 1, 2, 4, 3, clothed with greyish and other hairs, and armed with spines, 
the latter strongest and most abundant on the tibie and femora, especially on the tibie of the second pair. 
The exinguinal joint of the first pair have a short, curved, blunt-pointed, spiny process at their extremity 
on the outer side. They are of a yellowish colour, faintly annulated with yellow-brown. 
‘The palpi are short ; the cubital joints show the broken base of a strong spiny bristle in front of each; the 
radial joints are strongly and obtusely produced on their outer sides; the digital joints are clothed with 
coarse white bristly hairs, and have the base produced backwards and outwards into the curved process 
usual in males of this genus, but in the present species this process is broad and bifid at its extremity. 
The palpal bulb is large; the palpal organs are highly developed, prominent, and complex, and two large 
corneous curved processes project at their extremity on the outer side, both obtuse, but the hinder one 
longest and most curved. 
The mawille and labium are dark yellow-brown, tipped with yellowish. The sternum is dull yellowish, with 
an indistinct broad, tapering, central, longitudinal yellow-brown band. 
The abdomen is subtriangular, but rounded at each end. It is clothed with grey and other pubescence and a 
few erect and other strong bristles and hairs; at each shoulder it has a conical enlargement, and another 
smaller one on each side at the hinder extremity at the beginning of the vertical declivity to the spinners, 
and midway, but in a line between these two promiinences, is another, less strong prominence. The space
