EPEIRA. 37 
posterior side is much the shortest, the eyes forming this side being separated by a diameter. The ante- 
rior pair of eyes of this group appear to be rather the largest and to be separated from the lower margin 
of the clypeus by an eye’s diameter. Those of each lateral pair are seated on a tubercle, nearly contiguous 
to each other, and very slightly obliquely. 
The falces are long, powerful, and vertical; they are of a deep brown hue, marked in front with a rather 
oblique yellowish line or narrow stripe, and paler brownish-yellow towards the extremities. 
The legs are tolerably long, strong, 1, 4,2, 3, or 1, 2, 4, 3, of an orange-yellow colour, distinctly annulated 
and marked with rich deep yellowish-brown; they are furnished with hairs and bristles and armed with 
spines, of which many are white wholly or in part. 
The palpi are similar to the legs in colour and armature. 
Tho mazxille and labiwm are rich black-brown, tipped with pale yellowish-white. The sternum is dull orange- 
brown, clouded with dark brown along the middle and on the margins. 
The abdomen is large, of a somewhat subtriangular form, though rounded at both extremities; at each of the 
shoulders it is strongly and conically prominent, as well as on each side at the hinder extremity, where 
it falls perpendicularly to the spinners, and between the two hinder prominences and in the same line is 
another very much smaller one. The abdomen appears to be densely clothed with a velvety-looking 
pubescence, and its general colours are black and rich brown mixed with a little yellow-brown, and with 
a pattern indicated chiefly by short white hairs—this comprises a strongly dentated line from each of the 
anterior prominences to the posterior prominence on its side. The are thus included has a mixture of 
black and brown patches, among which is conspicuous a large, round, convex, boss-like, shining central 
spot edged (like other portions) with white hairs; and in front of it, a little in advance of the prominences, 
is another large oval black spot of a similar kind. The underside is black, with a cream-yellow spot a 
little way in front of the genital process, which is rich black-brown, prominent, and continued by a long, 
strong, tapering red-brown epigyne; this latter runs backwards parallel to the surface of the abdomen, 
and its point reaches nearly halfway to the spinners, covering and extending beyond the yellow spot 
mentioned above. 
Hab. Panama, Bugaba (Champion). 
This fine handsome spider would probably present many varieties of colouring on 
examination of a series of examples. 
Epeira clavispina, sp. n. 
Adult female, length 4-53 lines. 
Cephalothorax dull orange, clothed with white hairs and pubescence, especially on the caput and fore part 
of the thorax, the grooves showing the thoracic junction with the caput deep bistre-brown; behind 
these are also some short lines of the same hue, converging to the median thoracic junction (which is also 
similarly marked), and indicating the segments of the thorax ; these lines, with a brownish-orange ground- 
colour, form an irregular curved band on either side. The caput, instead of sloping forwards, is rather 
raised towards the ocular area, which is prominent in the middle, where the ordinary central group of 
eyes is seated, thus leaving a clypeus of much greater width than usual in this genus, being very nearly 
equal to half that of the facial space. 
The eyes are on black spots and in the usual three groups; the central group forms a square whose posterior 
side is shortest on the almost vertical face of the middle of the caput, and the space in the middle of the 
square is a little drawn out into a blunt conical point surmounted by a single short black spine; the 
posterior eyes of this group are larger than the anterior, and are separated from each other by an eye’s 
diameter. Those of each lateral pair are very small and distinctly separated from each other. 
The falces are strong, tolerably long, yellow, and suffused with reddish-brown at their extremities. 
The legs are moderately long and strong, 1, 4, 2, 3, similar in colour to the cephalothorax. The femora are 
broadly and distinctly, some of the other joints faintly, annulated with black-brown ; they are furnished 
with hairs and bristles and armed with spines, of which many are marked with white at the base or tipped 
with black-brown, and some of the strongest are of a clavate form, the most characteristically formed of 
these being on the femoral joints.
