LINY PHIA.—PHYLLONETHIS. 307 
Eyes of posterior row forming a curve whose convexity is directed backwards ; the hind-centrals are a diameter’s 
distance apart, and considerably nearer to each other than to the hind-laterals. Central quadrangle 
scarcely longer than broad, and its anterior side slightly shorter than the posterior; height of clypeus 
about half that of the facial space. 
Legs moderately long, 1, 4, 2,3. Colour brownish-yellow, tinged with reddish; the anterior extremities of 
the tibize and metatarsi have the rim red-brown. Spines few and slender. 
Falces strong and a little prominent in front about the middle. Colour yellow-brown. 
Mazxille paler than the falces. 
Labium and sternum dark yellow-brown. 
Abdomen oval ; high, and somewhat produced at its hinder extremity, which slightly projects over the spinners, 
but is less caudiform than that of Z.leta,Cambr. The upperside is closely mottled with minute somewhat 
cream-white spots; a longitudinal central dull brown line, with some small lateral prominences, occupies 
the median line of the anterior half; at the hinder extremity above is a large black subtriangular 
marking, whose apex is truncated, the interval between this and the spinners being black. ‘The sides 
have a large black area forwards, and the underside is black-brown, divided from the sides by a row of 
indistinct whitish spots and markings. The genital aperture is small, of a somewhat kidney-shaped 
transverse form.

PHYLLONETHIS, Thorell (Theridion, Walckenaer, ad partem). 
Phyllonethis trepida, Cambr. (sub Theridion). 
The adult female of this species was described (anted, p. 256). I have since come across a specimen of the 
male. 
Adult male, length 1} to 13 lines. 
The male resembles the female in colours and in the pattern on the cephalothorax and abdomen ; but the legs 
are longer, especially those of the first pair: the lst, 2nd, and 4th pairs have a more or less deep and 
well-defined black-brown to reddish-brown annulus at the fore-extremity of the tibia, and the Ist and 
2nd pairs have also one at the fore end and middle of the femora, and one also at the middle of the tibiw 
and metatarsi of the first pair, and a smaller annulus or spot at the fore end and middle of the tibie and 
fore end of the metatarsi of the second pair. The legs are thus more or less sparsely annulated, with 
probably some variation in different examples. 
The falces are long, divergent, with a strong tooth-like prominence towards their base on the outer side, and 
another still more tooth-like prominence on the inner margin towards the fore extremity. 
The height of the clypeus slightly exceeds half that of the facial space. 
The palpi are moderately long, pale yellow, the cubital and radial joints are both short, the former with long 
bristles in front, the latter strongest and considerably produced at the fore extremity on the outer side, the 
produced portion having its outer edge fringed with a row of long, strong, tapering, curved bristles. The 
digital joint is oval and of moderate size, and furnished with long bristly hairs: the palpal organs are 
compact and not very complex, with a prominent, pointed, corneous process near the extremity; the 
humeral joint has along its outer side a row of strongish bristly hairs, each springing from a minute 
tubercle. 
The maaille are long, strong, a little enlarged towards the extremities, which are obliquely truncate on the 
outer side and inclined towards the labium. 
The labiwm is broader than bigh and of a somewhat subtriangular form. 
Hab. Mexico, Amula and Omilteme in Guerrero (//. [. Smith). 
It may not be easy to determine with certainty the generic position of the female by 
itself of a species of this group, but the adult males in the peculiar development and 
armature of the falces and the strength and length of the maxille are very conspicuous, 
and easily separated from the typical Theridion.
