HELVIDIUS.—ERVIG. 221 
Helvidius lugubris, sp. n. 
Adult female, length 3? lines. 
Cephalothorax deep reddish-brown, the sides marked with black, and with a broadish central and a marginal 
longitudinal stripe on each side of a paler hue densely clothed with white hairs, 
Eyes of the anterior row subequal, the centrals perhaps slightly the largest, and separated from each other by 
distinctly less than a diameter, each being contiguous to the fore-lateral eye next to it. The quadrangle 
of the four central eyes is at least one and a half times longer than broad at its widest point; the 
centrals are smallest and are separated by one and a half diameters from each other and from the laterals 
by distinctly less than a diameter. 
Legs yellow-brown; the third and fourth pairs darkest. 
Palpi similar to the legs in colour and spinose. 
Falces dark yellow-brown tinged with red and furnished in front with long, strong, bristly hairs. 
Mawille similar to the legs in colour. 
Labium and sternum dark brown. 
Abdomen thickly clothed with short hairs, jet-black above, with two longitudinal narrow but well-defined bright 
white stripes on the upperside; the black portion bounded laterally on each side by a similar but rather 
yellower stripe, terminating at each posterior extremity with an oblique stripe of the same colour and 
running below the spinners ; sides and underside of a dull brownish hue. Spinners dark brown; genital 
aperture neither large nor conspicuous, but of characteristic form.

Ervig propinquus, sp. n. 
Adult female, length 33 lines. 
This spider is very nearly allied to Z. albolineatus (antea, p. 151, t. 19. fig. 3), and resembles it very closely 
in pattern and distribution of colours. It is, however, rather larger and more robust, the colours are 
darker and brighter, the legs are brightish yellow and have dark reddish-brown annuli (not present in 
E. albolineatus) near the middle of the femora, tibie, and metatarsi, as well as those at the anterior 
extremities of these joints which are found in that species; the abdomen is obtuse at the upperside of 
the posterior extremity, but wants there the subconical prominence of E. albolineatus. The eyes form a 
wider transverse line, the interval between the central and lateral groups being considerably greater ; 
those of the central group also appear to be more oval in shape. The maxille taper towards their 
extremities, and are strongly impressed transversely at the middle: this character was not noted 
(anted, p. 151), but is common to both species.

The female only of this species was described. I have since come across an adult 
male of it among the spiders of Mr. H. H. Smith’s collection. 
Adult male, length nearly 23 lines. 
This sex resembles the female exactly in colours and markings, but the abdomen is much less robust and 
convex above, being of a somewhat elongate cylindric-oval form; the upperside, however, of the 
posterior extremity is similarly subconically prominent. The first pair of legs are also of a darker 
yellow-brown hue. The palpi are short; the cubital joint is very short and has several bristly hairs at its 
fore extremity on the upperside; the radial joint is very much larger and of a tumid form ; the digital 
joint is small and has its fore extremity above drawn out into a rather long, tapering, pointed form, 
furnished with a few long bristly hairs, and its inner side also produced into a somewhat similar but 
shorter and stronger apophysis ; the palpal organs are simple, consisting of an oval corneous bulb whose 
fore extremity is produced in a slightly tapering form into a long, corneous, concave, obtusely-pointed,
