ERVIG. 151 
ERVIG *, gen. nov. (Sicariide). 
Cephalothorax flattened, elongate-oval, twice as long as wide, roundly truncate before and more squarely 
truncate behind; the normal grooves between the caput and thorax strong ; the central impression at the 
junction of these two large, deep, circular, and pit-like ; lateral marginal impressions at caput slight. 
Eyes six, in three pairs, of moderate and about equal size—a central pair ona slight tubercle, contiguous to each 
other, and a pair on each side at the extreme width of the caput, on a very strong geminated tubercular 
eminence, that of the anterior eye strongest; the eyes of each lateral pair are nearly but not quite con- 
tiguous to each other, and form a line at right angles to the nearly straight line of the central pair and 
the fore-lateral eyes ; the two posterior eyes are misshapen, of rather a subtriangular form, and as large 
or rather larger than the fore-laterals. 
The clypeus is prominent, convex, and its height is about equal to the diameter of two of the central eyes. 
Legs moderate in length and strength, not greatly unequal: 1, 4, 2,3. Clothed with numerous rather long, 
somewhat bristly hairs, but without spines; terminal tarsal claws three, on a small distinct claw-joint ; 
the superior claws armed throughout nearly the whole length with long teeth (on the first pair eight); the 
inferior claw long, nearly straight, but bent sharply downwards at its base, close beneath which is a single 
tooth. At the side and beneath the terminal claws at the extremity of the tarsus are various opposed 
supernumerary pectinated claws or spines. 
Palpi short, armed like the legs; digital joint equal to the radial and cubital together ; without terminal claw, 
but ending in a short, sharp, corneous point on the upperside. 
Mawille long, strong, much bent, and inclined over the labium so that their extremities almost meet. 
Labium oblong. 
Falces moderately long and strong, straight, vertical, subconical ; fang very short, curved, and its point, 
though sharp, broad when looked at from below. 
Sternum oblong-oval, about twice as long as broad, blunt-pointed behind, the fore extremity somewhat drawn 
out and hollow-truncate. 
Abdomen oval, the upperside of the posterior extremity drawn out into a not very strong subconical promi- 
nence, whence it slopes underneath backwards in an incurved line to the spinners. The spinners are 
closely grouped, the four outer ones short, about equal in strength, the hinder ones slightly longest: these 
last are much wider apart than the fore ones, and with them form very nearly a semicircle. 
Ervig albolineatus, sp. n. 
Adult female, length from 3 to 4 lines. 
The cephalothorax is flattened, so that the caput and thorax are level with each other; it is yellow-brown 
in colour, clothed with coarse, adpressed, white hairs, some of which form a rather distinct submarginal 
line on each side; two other lines similarly form an elongate somewhat drawn-out oval figure from the 
middle of the ocular region to the thoracic fovea; this figure has its hinder half longitudinally bisected 
by a fine line of similar white hairs. Some of the hairs also on the sides of the thorax show a tendency 
to converging lineation. 
The legs are yellow, the basal half of the femora, the genua, and the extremities of the other joints strongly 
tinged with reddish yellow-brown. 
The mawille, labium, falces, and sternum are dark reddish-yellow-brown, thinly clothed with coarse white 
hairs like the cephalothorax ; on the sternum some of these hairs also form a marginal line on each side 
and a central longitudinal one. 
The abdomen is of a pale dull luteous colour, thickly clothed with fine, adpressed, yellowish-grey hairs ; a longi- 
tudinal band, narrow at the fore extremity and gradually widening to the posterior abdominal tubercle, 
which it encloses, and to which for a short distance it converges, is margined by a very distinct but fine 
wavy line of white hairs; this band is clothed with yellowish hairs deepening to a dull golden at its 
hinder extremity; an elongate-oval dark brown figure, similarly margined, runs from the abdominal 
tubercle to the spinners, where it is met by a still broader dark brown band, similarly bordered, running 
the whole length of the underside of the abdomen, and including the spiracular plates and the genital 
aperture. This last is simple, forming a largish transverse slit.
