EPEIRA. 19 
The abdomen is oblong-cylindric, well rounded at its posterior extremity, which projects rather over the 
spinners. The sides and upperside are of a blackish hue, with an oblique whitish stripe towards each 
lateral margin converging towards the spinners, which, however, it does not reach ; from the hinder half of 
this stripe, on each side, several whitish stripes fall vertically over the sides, and along the middle of the area 
included between the two lateral stripes is a white longitudinal somewhat dagger-shaped tapering band, 
bisected longitudinally by a strong black line or stripe ; on the middle of the upperside are six or eight 
small rust-red spots in two longitudinal lines or three or four pairs. The underside is yellowish or 
brownish-yellow, with a large blackish central patch. Spinners short, compact, and of a brownish-orange 
colour. The genital process is large, deep blackish-red-brown, and prominent; the epigyne is short, broad, 
somewhat bluntish subtriangular at its extremity, and transversely rugulose (in one example this portion 
les parallel to the surface of the abdomen, in the others it is only slightly directed backwards). 
Hab. Panama, Bugaba (Champion). 
A very handsome and distinct species. 
Epeira cylindrica, sp. n. 
Adult female, length 3 to 4 lines; adult male, slightly over 23 lines. 
2. Cephalothorax longer than broad. Caput nearly as broad as the thorax ; sides almost parallel ; occiput rather 
raised and well rounded, and sloping forwards to the ocular area ; height of the clypeus equal to the diameter 
of one of the fore central eyes. The colour is a brightish orange-brown, with a submarginal border, which 
crosses over behind the lateral eyes and meets the central group, and also a longitudinal central stripe and 
two oblique ones (along the junction of the caput and thorax), of a dark red-brown ; these markings 
are obsolete in some examples. The cephalothorax is covered thinly with fine whitish hairs. 
The eyes are in the ordinary three groups and seated on tubercular prominences. The hind central eyes are 
separated from each other by no more than half an eye’s diameter, those of the fore central pair (which are 
largest of the eight) by a diameter’s interval. The four central eyes form a square whose posterior side 
is considerably the shortest. The eyes of each lateral pair are very small, contiguous, and somewhat 
obliquely placed. 
The legs are rather strong, not very long, 1, 2, 4, 3, of the same colour as the cephalothorax, clouded in parts, 
or, rather, broadly but indistinctly annulated with darker reddish-brown, and this is generally only visible 
on those of the third and fourth pairs. The legs are armed with spines, most numerous and strongest 
beneath the tibie of the first and second pairs. 
Falces strong, moderately long, prominent at their base in front, straight, vertical, and varying in colour from 
orange to dark orange-red-brown. 
Mawille dark reddish-yellow-brown, and pale whitish at the extremity. Labiwm darker in colour than the 
maxilla. Sternum dark yellow-brown. 
Abdomen cylindrical, and produced at its hinder extremity rather considerably over the spinners ; the fore 
extremity projecting over the thorax. It is of a dull greyish-drab in the spirit-preserved specimens (but 
Mr. Sarg says in his notes that it is of “a peculiar shade of purplish-yellow ” in the living spider), striped 
longitudinally on the upperside with four white stripes, and marked with six small impressed red-brown 
spots in three pairs, or two longitudinal lines. A broad longitudinal black band, strongly bent towards its 
posterior extremity, occupies each side ; there are also some black markings at each end of the upperside, and 
a broad transverse black band across the underside just behind the genital process, which is oval, convex, 
of a deep reddish-bistre-brown colour, slightly rugulose transversely, and with a narrow transverse aperture 
behind. Spinners short, strong, compact, and of a brownish-orange-yellow colour. 
The male resembles the female in general characters and colours as well as markings in the immature state, 
put in the adult the abdomen is marked on the upperside with three longitudinal blackish lines or slender 
stripes, the intervening space being of a whitish drab. According to Mr. Sarg, “ the abdomen is yellow- 
ochre, with three longitudinal sharp brown lines.” The dark submarginal border and other markings of 
the cephalothorax are more richly coloured and more conspicuous than in the female. The spines on the 
legs are also stronger, and there is one stronger than the rest at the fore extemity rather on the inner 
side of the tibiee of the second pair, with another similar one a little way behind it and beneath the joint.
