184 °° ARANEIDEA, 
ANYPHZENA, Sundevall. 
Anyphena clubionoides, sp. n. 
Adult male, length 24 lines; female, slightly over 23 lines. 
Cephalothorax yellow to orange-yellowish, with a broken more or less distinct narrow longitudinal stripe on 
each side formed by the bases of converging lines, of which the remainder is obsolete. 
Legs, palpi, and falces similar in colour to the cephalothorax. : 
Palpi (of the male) moderately long and strong; radial and cubital joints short, and about equal in length, the 
former rather longest, a single long, strong, filiform-ending bristle at the fore extremity on the upperside of 
the latter ; others (8-4) shorter, but as strong on the former (radial); at the fore extremity on the outer side. 
of this joint isa group of strong, pale, bristly hairs, and (its base almost concealed by them) an apophysis 
nearly or quite as long as the joint, its base having a kind of concave enlargement above; the longer 
portion straight, somewhat like the blade of a knife, its obtuse point resting beneath the base of the digital 
joint on the edge of the palpal organs; at the base of the radia] joint on the outer side beneath is an 
obtuse prominence. The digital joint is large, as long as the humeral joint, oval, densely clothed forwards 
with long, strong, pale, bristly hairs. Palpal organs highly developed, not very complex, consisting of 
several strong, curved, corneous processes. On the inner side of the humeral joint are numbers of short 
minute bristles and granulosities, perhaps used for rubbing against some stronger and numerous. 
punctuosities on the outer side of the falces, and producing probably stridulating sounds. 
Mazille and labium similar in colour to the cephalothorax ; sternum yellow. 
Abdomen pale luteous-yellowish, marked on the upperside with short, brownish, linear spots, the most notice- 
able among which represent on the hinder part the ordinary longitudinal central series of the normal 
angular markings or chevrons. 
The female resembles the male in colours and markings, but is paler. The genital aperture is not very large, 
but of distinctly characteristic form. The transverse spiracular opening on the middle of the underside of | 
the abdomen is rather indistinct in both sexes. 
Hab. Mexico, Amula in Guerrero (H. H. Smith). 
It is not without some doubt that this spider is given as new, there being a 
considerable number of species of this genus described by the late Count Keyserling 
from North and South America. The species, however, run very closely together, 
and the figures (where given) and descriptions leave their identity by no means a 
matter of certainty; it is therefore, I think, better to risk it as new, with good 
figures (which will tend to less confusion in the end), than to label it uncertainly as 
one of those already described. 
OPAS *, gen. nov. (Epeiride). 
Cephalothorax longer than broad; lateral marginal impressions at the caput moderate ; normal indentations 
strong, especially that at the thoracic junction ; upper convexity moderate; height of the clypeus greater 
than the diameter of the fore-central eyes. 
Eyes of tolerable size and occupying the whole width of the caput, subequal; the hind-laterals smallest, the 
fore-laterals rather the largest ; the fore-central pair on a strong tubercular prominence, each lateral pair 
on a tubercle; the hind-centrals nearer together than to the hind-laterals; the convexity of the slightly 
curved posterior row is directed forwards; the anterior row, which is very strongly curved, has its 
convexity also in the same direction. The four central eyes form a quadrangle a little longer than broad ; 
its fore side but slightly, if at all, wider than its hinder side. 
Legs short, 1, 2, 4, 3, moderately strong, destitute of spines, excepting a slender one at the fore extremity of 
the genual joints. The femora of the fourth pair bent inwards, and two-thirds of their length from the
