ELAVER. 2359 
tibiee of the first and second pairs (see characters of genus). Colour similar to that of the cephalothorax, 
excepting the tibie, metatarsi, and tarsi, which have a deeper hue. Scopula beneath the tarsi and meta- 
tarsi of the first and second pairs rather dense, also beneath the tarsi and anterior part of the metatarsi 
of the third and fourth pairs. Tarsal claws 2, and beneath them a small compact claw-tuft. 
Palpi rather short. Colour like that of the legs; cubital joint short; radial joint double the length of the 
cubital, curved, and with a strong, somewhat triangular, deep red-brown apophysis at its fore extremity 
on the outer side; digital joint large, oval, considerably longer than the radial, with which it is thickly 
furnished with long coarse hairs, those at the fore half of the digital joint being of more equal length, 
dense, and of a pale yellowish-grey colour. Palpal organs highly developed, prominent, consisting 
principally of an elongate ridge-like corneous lobe. At the fore extremity of the humeral joint are four 
spines, three in a transverse row and one just behind them. 
Falces moderately long, strong, straight, a little directed forwards. Colour deep red-brown. Furnished in 
front with numerous coarse hairs. 
Mazille dark yellow-brown, long, much broadest at the extremity, which is rounded on the outer side and 
obliquely truncated on the inner side. 
Labium higher than wide ; sides straight, apex slightly emarginate. Colour like that of the falces. 
Sernum oval, flattish, slightly emarginate in front, pointed behind. Colour yellow. 
Abdomen elongate, semicylindric, somewhat roundly truncate in front, obtusely pointed behind. It is of a 
dull yellowish colour, and clothed pretty thickly with longish paler hairs ; the fore half of the upperside 
is covered with a shining, somewhat coriaceous epidermis of a yellow-brown hue. The ordinary central, 
longitudinal, tapering marking is indistinctly visible on the fore half, and bas a prominent point on 
each side at a third of its length from the posterior end, where it is followed by six or seven tolerably 
distinct transverse dark brown lines or stripes, formed by the remains of the normal triangular bars or 
chevrons continued on each side by curved, oblique, lateral bars. Spinners long; inferior pair strongest, 
superior pair with a short second joint. 
The female is rather smaller than the male. The eyes appear to be of a more uniform size, and the markings 
on the abdomen are more distinct. The spines beneath the tibice of the first two pairs of legs are four only 
(in two pairs). The genital aperture is large and of a very distinct and characteristic form. 
Hab. Mexico, Orizaba (H. H. Smith). 
Note by Mr. Smith :—‘*Spider in a crevice in bark on the lower side of a large 
projecting tree overhanging a bank by the side of a river, a somewhat shady place. 
The spider had a soft, white, silken egg-case, and under the place of concealment was 
a thin irregular web about five inches in diameter stretched over the bark.” In another 
case “brushed from weeds and bushes.” 
Elaver sericea, sp. n. 
Adult female, length 53 lines. 
This species is nearly allied to E. tigrina, which it resembles closely, but the profile of the cephalothorax 
appears to be more convex. The whole of the fore part is orange-yellow, the cephalothorax, falces, 
maxille, and labium tinged with brown. The eyes of the posterior row are equidistant from each 
other, and the height of the clypeus is equal to half the diameter of one of the fore-central eyes. The 
abdomen shows traces of a similar pattern to that of Z. tigrina, the remains of it being here represented 
by three longitudinal converging lines of brown spots and markings on the hinder half of the upperside. 
The clothing of the abdomen is more silky, and the genital aperture is characteristic and of a different 
form from that of E. tigrina. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Mr. Smith’s note on this spider is “shaken from a branch of fruit, edge of forest ; 
there were a few short irregular lines in the fruit.”
