22 ARANEIDEA. 
In the form of the cephalothorax and some other characters, this spider and E. pas- 
siva (p. 20) are closely allied to the two species of Mangora (supra, p. 14, Tab. III. 
figg. 5, 6, 7), with which I should have coupled them had it not been for the strong 
opinion to the contrary of Count Keyserling. 
Epeira graphica, sp. n. 
Adult male, length rather over 13 line. 
Cephalothoraw of ordinary form; caput moderately broad, prominent at the middle in front, the sides nearly 
parallel; the colour is yellow, with a large wedge-shaped deep brown area, including the upper part of 
the caput, the ocular area, and reaching to the thoracic indentation, where it ends in a point. 
The eyes are in the usual three groups; those of the central group are rather large and prominent, though 
apparently not differing much in size, but the hinder pair form a line less in length than the anterior 
pair, whose eyes are about half a diameter’s distance from the lower margin of the clypeus. 
The falces are moderately long, not very strong, yellow, with a black spot at the base in front towards the 
inner side. 
The legs are tolerably long, moderately strong, 1, 2, 4,3; the femora are blackish, but pale yellow at the base, 
the genua blackish, the rest of the legs annulated with blackish and pale yellowish, the first and second 
pairs tinged with brownish. They are furnished with hairs and a few not very strong spines, the latter 
mostly on the tibiee of the first and second pairs. 
The palp: are short, yellowish, the digital joint dark yellow-brown; palpal bulb of fair size; palpal organs 
prominent, not very complex, with a pale, curved, projecting corneous process, obtusely truncated at the 
end, at their extremity. 
The sternum is of a rather narrow-oval form, yellow, with a black longitudinal central marking. 
The abdomen is a regular oval, a little constricted across the middle (unless this is due to shrinking in spirit 
of wine) towards the margins of the upperside; on each side is a longitudinal, slightly indented,.white 
streak or stripe, edged on each margin with black, most conspicuous at the fore extremity, and fining off 
indistinctly at the hinder parts, and within this at the anterior end there is on each side of the median line 
(which is occupied by a short, bright white central tapering stripe) a jet-black spot, interrupted in the middle, 
but continued quite to the fore edge of the abdomen; from the point of the central white stripe towards 
the hinder extremity are some small ocellated whitish-yellow spots, followed by some narrow obscure 
transverse blackish-brown bars in a longitudinal series ; the ground-colour of the upperside of the abdomen 
is brownish, the underside being black. 
Hab. Panama, Bugaba (Champion). 
Epeira gregalis, sp. n. 
Adult female, length from 33-42 lines. 
Cephalothorax rather oblong-oval. Caput broad and well rounded above, the sides very nearly parallel. Colour 
yellow-brown, the caput entirely rich dark yellow-brown and glossy, and the thorax margined narrowly 
with brown, and some converging lines of the same colour on the sides following the normal grooves. 
The eyes are small and in the usual three groups. The four central eyes form a square, whose posterior side is 
much the shortest, and its eyes are almost contiguous to each other, those of the anterior side being on 
strongish tubercles. 
The falces are rather long, powerful, and very prominent and rounded in front towards their base. They are 
directed rather backwards, and are very glossy, and similar in colour to the caput. 
The legs are short, strong, 1, 2, 4, 8. They are of a yellowish-brown colour, paler on the femora, furnished 
with hairs and spines ; the latter not very conspicuous. 
The palpi are similar to the legs in colour and armature, the humeral and cubital joints the palest, like the 
femora of the legs. 
The maville, labvum, and sternum are dark yellow-brown, the two former tipped with yellowish-white. 
The abdomen is of an exact oval. Its colour is dull yellowish-white, covered, but not densely, with hairs; a
