34 ARANEIDEA. 
than broad ; the posterior pair of eyes are larger than the anterior, which last are separated from the lower 
margin of the clypeus by an eye’s diameter. The eyes of each lateral pair are almost contiguous to each 
other, and are placed in a parallel line to the lower margin of the caput. 
The falces are strong, vertical, prominent near the base in front, and of a dull yellowish hue. 
The legs are short, 1, 4, 2, 3, or 1, 2, 4, 3, moderately strong, of a brownish-yellow colour, faintly annulated 
with yellow-brown, mostly so near the anterior extremities of the femora. They are furnished with hairs 
and spines, but most of them are rubbed off, though, judging from what remain, the spines are not very 
long nor strong, nor very numerous. 
The palpi are similar to the legs in colour and armature. 
Mawille and labium yellow-brown, tipped with pale yellow. Sternwm brownish-yellow. 
The abdomen is large, short heart-shaped, or subtriangular, a little broader in front than long, somewhat sub- 
angular before as well as behind, and projects greatly over the thorax. At the broadest part in front 
there is a slight subangular prominence on each lateral margin at the shoulders, and close behind it, on 
each side, a sharply dentated deep brown line runs backwards towards the spinners, where the two lines 
converge and almost unite. The triangular area included between these dentated lines is dark yellowish- 
brown, the rest of the upperside and sides being of a dull hue closely mottled with whitish cretaceous 
spots; in the middle of the most prominent part of the anterior extremity is a large white spot. The 
sides have some broken blackish markings, and the underside, which is of a dull brownish colour, has two 
white blotches, one on each side of the median line, halfway between the frontal process and the spinners. 
This process is prominent and characteristic in form, and has a slender, sinuous, transversely rugulose 
epigyne directed horizontally backwards over its aperture. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This spider belongs to the Z. angulata, Clk., group. 
Epeira rufa, sp. n. 
Adult female, length 4 lines. 
This fine species is of the EZ. angulata, Clk., group. 
The cephalothorax is of a brownish-orange-red colour, clothed with fine greyish hairs. 
The eyes are in the usual position ; those of the central group form as nearly as possible a square, whose pos- 
terior side may be very slightly longer than the anterior; the eyes forming the posterior side are of an 
amber colour and are larger than the others, though nearer together. The height of the clypeus is about 
equal to the diameter of one of the fore centrals. 
The falces are powerful, vertical, and similar in colour and clothing to the cephalothorax. 
The legs are moderately long and strong; they are of an orange-brown colour annulated with yellow, the 
extremities being reddish-bistre-brown ; their relative length is, 4, 1, 2, 3, though the difference, if any, 
between 4 and 1 is very slight. They are armed with not very strong spines, and clothed with greyish 
and other hairs. 
The palpi are similar to the legs in colour, markings, and armature. 
The sternum is similar to the cephalothorax in colour, but of a deeper hue towards the margins, and clothed 
with greyish hairs. 
The mawille and labium resemble the falces in colour, but are paler at their extremities. 
The abdomen is large, subtriangular, projects well over the base of the cephalothorax, and is produced at its 
fore extremity on either side into a strong, pointed, conical eminence. Its colour is a uniform brownish- 
yellow tinged with reddish, and darkest in front. It is clothed with fine greyish pubescence, and has a 
few dark bristles and hairs. Between the spinners (which are strong, short, and compact) and the genital 
aperture are two large cream-white blotches in a transverse line. The genital process is large, prominent, 
and of an obtuse transverse shape, with an epigyne of a short, broad form, rounded at the extremity, 
and directed a little backwards over its aperture; its colour is a shining rich brown-black.

pion).
