line, and above again, a little way behind the point where the triangular patches join, is also a short 
transverse line formed by two small contiguous silvery spots; between these spots and the upper angles 
of the large silvery patches the colour is reddish-brown. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
PELAYO, gen. nov. (fam. Drasside ; subfam. Anypheenine). 
Cephalothorax broad-oval, longer than broad; lateral marginal impression at the caput slight, profile almost 
level; lateral margin of caput rather converging forwards; fore margin truncate; fore part of caput 
prominent, moderately and uniformly convex, hinder slope very abrupt; lateral indentations obsolete, 
thoracic indentation slight, linear, longitudinal; clypeus strongly impressed, about equal to the diameter 
of the fore-central eyes in height. 
Eyes rather widely disposed, the anterior row shortest and seated upon the somewhat prominent fore part of 
the caput. ‘he curves of both rows subsimilar, that of the anterior row rather strongest and their con- 
vexity directed forwards. The hind-central eyes are smallest, the hind-laterals largest, the fore-centrals 
rather larger than the fore-laterals. The four central eyes form a quadrangle a little wider than long, 
and its anterior side shortest; the interval between the hind-centrals is equal to about two and a half or 
three diameters, and each is two diameters from the hind-lateral eye on its side ; the fore-centrals are rather 
more than half a diameter from each other, and about half that distance from the fore-laterals. 
Legs rather short, subequal, 1, 4, 2, 3, tolerably strong, the femora of the first pair much the strongest, spinose, 
excepting the tarsi, which are somewhat incrassated; a thin scopula beneath the tarsi and metatarsi of 
the first and second pairs. Tarsal claws pectinated, and a claw-tuft beneath them. 
Falces moderate in length and strength, straight, projecting forwards, with two or three small teeth on the 
upper margin at their inner extremity, which is thickly set with strong bristly hairs; the front near the 
base is prominent, and on the outer side at the base is a small, oval, shining prominence. 
Mawille moderately long, straight, much the broadest at their extremity, which is rounded on the outer and 
rather obliquely truncated on the inner side; no transverse impression. 
Labium rather higher than broad, a little the widest halfway up, and thence sloping to the apex, which is 
rounded. Its height is a little more than half the length of the maxille. 
Sternum longer than broad, truncated before, its hinder extremity rather drawn out into an obtuse broad point 
between the coxe of the fourth pair of legs. 
Abdomen oval, somewhat flattened above. Spinners of the inferior pair stronger but shorter than the superiors, 
these two pairs apparently 3-jointed. 
Pelayo letus, sp. n. 
Adult male, length 17 lines. 
Cephalothorax deep dusky yellow-brownish tinged with olive, very glossy, clothed thinly with fine hairs ; 
falces darker than the cephalothorax, and furnished with long bristles on their inner sides in front. 
The maville and labiwm are similar in colour to the cephalothorax, and the sternum is of a pale greenish hue, 
with the posterior extremity maroon-brown, margined with bristly hairs. 
Palpi short, furnished with spines and bristles, the former on the humeral, cubital, and radial joints very short 
and of equal length, the latter without any distinct apophysis; beneath the humeral joint at its fore 
extremity is an obtuse, bent, corneous apophysis directed fowards; digital joint large, oval ; palpal organs 
simple, consisting of several curved corneous processes and spines. 
Legs yellow-brown tinged with reddish ; femora deep blackish-maroon-brown ; tarsi and metatarsi of third and 
fourth pairs paler than the rest ; the coxal and exinguinal joints are clear pale yellow. 
Abdomen of arather rich maroon-brown, with a large, oval, central, longitudinal, well-defined band of yellowish- 
white on the upperside, and another broad band of the same colour along the lower part of each side; 
these three bands do not reach the spinners, and all are clothed with short white hairs. Spinners maroon- 
brown, the bases of the four outer ones striped longitudinally with yellowish; plates of the spiracles 
yellowish-white. On the underside of the abdomen towards the spinners is a strong, straight, transverse 
slit or fold in the epidermis, no doubt indicating the aperture to additional spiracular organs. 
Hab. Costa Rica (Sarg).
