EPEIRA. Al 
a brownish hue irregularly marked with darker spots and lines; the anterior portion of the abdomen is 
also more produced. 
The cephalothorax is dark reddish-yellow-brown, with the caput and thoracic margins yellowish. The ocular 
region is rather produced forwards, and the falces less strong than in the female, and directed rather 
backwards. 
The legs are yellow, the femora of the first and second pairs dark brown, the other femora yellowish, faintly 
annulated with a darker hue; armed with spines, these being most conspicuous on the tibis of the first and 
second pairs. 
The palpi are short, the palpal bulb large; the palpal organs well developed, complex, and prominent. 
Hab. Guatemata, Livingston, Chicoyoito, Polochic valley near Tamahu, Cubilguitz 
(Sarg). 
This spider belongs to the #. verrucosa, Walck., group. 
Epeira armata, sp. n. 
Adult male, length 3% lines. 
Cephalothorax of a somewhat oblong-oval form, rather broader at the fore part of the thorax than behind, the 
sides of the caput converging forwards. Colour yellow-brown, the occiput and normal indentations marked 
with broken lines and spots of dark yellow-brown. It is clothed with greyish hairs, of which there are 
some longer and stronger than the rest just behind each lateral pair of eyes. 
The eyes are of tolerable size and in the usual three groups. The four central eyes are on black spots and 
form a square whose posterior side is considerably the shortest, its eyes being separated by a diameter’s 
interval; the height of the clypeus appears to be about equal to the diameter of one of the fore central 
eyes. Those of each lateral pair are seated on a strong tubercle, contiguous to each other and slightly 
obliquely placed. 
The falces are moderately long, rather slender, or weak, the profile lines (both lateral and in front) hollow, and 
slightly directed backwards. They are of a pale yellow colour. 
The legs are rather long, strong, furnished with hairs, some grey, others reflecting greenish-golden tints in a 
strong light, and armed with numerous spines. The spines on the tibie of the first and second pairs, 
especially on the latter, are the most powerful ; some of them are pale whitish in the middle portion, others 
brown to red-brown. At the anterior extremity of the exinguinal (or basal) joints of the first pair of 
legs is a strong, prominent, but not very sharp-pointed spine, and at the fore extremities of the coxal (or 
2nd joints) of the fourth pair are three short, curved, sharp spines in a row; and in a similar position on 
the coxe of the second pair of legs is a small pointed corneous process, tipped with a small tuft of bristly 
hairs. This exinguinal and coxal armature is characteristic, though it is possibly only sexual. 
The palpi are short; the cubital joint has a long, strong, tapering sinuous bristle in front ; the radial joint is 
strongly and obtusely produced on its outer side; the palpal bulb is large; the palpal organs are of a 
rich deep red-brown colour, greatly developed, very prominent and complex, with strong corneous pro- 
cesses and spines. One enormous process, curved, rather enlarged and bifid, or cleft at its extremity, 
projects perpendicularly upwards on their outer side. The digital joint is furnished with long, bristly, 
grey and yellowish hairs. 
The maxille and labium are yellow-brown tipped with a paler hue. The sternum is pale yellowish. 
The abdomen is subtriangular, with a conical prominence at each of the shoulders, or lateral margin of the 
broadest part in front, and two others, one on each side of the hinder extremity where the declivity 
towards the spinners begins, these last two being only half the distance from each other that the others are. 
The abdomen is of a yellowish-brown colour, clothed with grey and other hairs reflecting greenish-golden 
tints in a strong light; there are also some strong dark bristles on the upperside; it is lined and reticu- 
lated with deep brown in front of the anterior prominences, and on the sides, where there are also numerous 
round light reddish-brown spots. In front of and between the two posterior prominences is an oblong dark 
brown area, reaching halfway to the anterior ones, with dentate lateral margins and a prominent curved 
horn-like prolongation at each of the fore corners, directed outwards and forwards. The anterior 
prominences are connected by a well-defined black-brown margin to the brown markings on the fore part,
