42 ARANEIDEA. 
which margin is also followed by a transverse stripe of whitish spots. The underside has broken. dark 
brown lateral margins and markings, with a central white spot. The spinners are short, compact, and of 
a yellow-brown colour. 
Hab. Panama, Bugaba (Champion). 
A fine distinct species. 
Epeira championi, sp. n. 
Adult female, length 2 lines ; adult male, 1% lines. 
The cephalothorax, legs, palpi, and sternwm are pale yellow, without any markings; the falces are similarly 
coloured, but have the extremities suffused slightly with blackish ; the mawille and labium are blackish, 
broadly tipped with yellow. The form and structure of these parts are normal. 
The eyes are in the usual three groups, widely separated from each other, and conspicuous from the black spots 
on which they are seated. The four centrals form a square whose anterior side is slightly the shortest, 
the posterior eyes being larger than the anterior. 
The falces are powerful, and rather prominent in front. 
The legs are neither very long nor strong, relative length 1, 2, 4, 3. They are furnished with hairs and a 
very few short fine spines. 
The abdomen is oblong, almost cylindrical, though rather narrowest behind; the hinder part scarcely projects 
over the spinners, but it is at least perpendicularly truncated there. The upperside is white, with a broad 
longitudinal central, more or less sooty or blackish band throughout its length. This band tapers or 
narrows towards the posterior extremity with a prominent angle at each side before, and has a series of 
white markings along it, more or less separated from each other, and ending in a point behind. The 
white on the upperside might perhaps be as well described as consisting of these markings and a broad 
longitudinal band on each side, and the central blackish band would then be described as somewhat 
irregular stripes with a projecting angle on the outer side near the fore extremity. The sides are marked 
with two longitudinal well-defined parallel bands, the upper one blackish, the lower one white; and the 
underside is entirely blackish, but between the spinners and the pattern on the upperside is a single 
larger or smaller oval or oblong white spot. In several examples all the portions above described as white 
are bright red-brown or rust-coloured, having only a narrow edging of white by the black markings. 
The genital process is prominent, of a rich dark red-brown hue, with a short curved epigyne directed 
backwards. 
The male resembles the female in colours and general characters, but the fore part of the caput is more pro- 
minent; the legs are longer and are armed, especially on the tibis of the first and second pairs, with long 
spines ; the pattern on the abdomen is often entirely interrupted in the middle, both on the upper part and 
on the sides. The palpi are short; the cubital joint has a single long, strong, tapering, prominent bristle 
in front; the radial joint is broad, projecting strongly and obtusely both on the outer and inner sides ; 
the palpal bulb is large, and the palpal organs are very prominent, highly developed, with lobes and 
corneous processes and spines. 
Hab. Panama, Bugaba (Champion). 
Examples of both sexes of this very pretty and distinctly marked spider were con- 
tained in Mr. Champion’s Chiriqui collection. I have no note of its colours when 
alive, but it is very possible that some of the colours now yellow are green in life. 
Epeira septem-mammata, sp. n. 
Adult females, length 24 and 3 lines. 
The cephalothorax is rather broad, and the caput is somewhat gibbous above towards the occiput; its colour is 
pale yellow, with a very broad dark bistre-brown central longitudinal band, including the upperside and 
part of the sides of the caput, and reaching from the eyes to the hinder part of the thorax.
