MACROPHYES.—HERSILIA. 107 
Palpi long, slender ; armed like the legs. 
Falces long, divergent, and projecting. 
Mamtlle \ong, rather divergent, broad at the extremity, which is rounded on the outer, and cut away on the 
inner side. 
Labiwm about half the length of the maxilli, the lateral margins slightly curved; the apex truncated, but 
slightly depressed or hollow in the middle. 
Sternum oval. 
Abdomen very long, narrow, cylindrical but slightly tapering to the spinners, the superior pair of which are 
much longer than the inferior, and two-jointed. % 
This genus is nearly allied both to Cludiona and Chiracanthium. 
Macrophyes attenuata, sp. n. 
Adult male, length 4 lines ; length of cephalothorax 1 line, length of abdomen 3 lines. 
The cephalothorax, falces, and maxille are yellow, the legs, palpi, and sternum rather paler, and the abdomen 
is of a pale luteous-yellow. 
The radial joint of the palpus is slightly curved, very long, and”almost equal in length to the humeral joint, 
and has a small rather tapering blunt-pointed apophysis at its extremity on the outer side; the digital 
joint is also long and narrow, furnished with coarse hairs, and with a large lobe on the outer side. The 
palpal organs are well developed, prominent, not very complex, consisting of a large oval lobe, encircled 
with a long, slender, closely-fitting, sinuous spine ; a short sharp-pointed dark spine, and a bent, obtusely- 
pointed corneous process are near together at their extremity. 
The eyes are seated on black tubercles and are all of a pearly lustre, excepting the fore-central pair, which are 
dark, and much the smallest of the eight; the other six are nearly of uniform size, the fore-laterals being 
the most prominent ; the hind-centrals are oval and separated from each other by rather a wider interval 
than that between each and the hind-lateral eye next to it. 
The falces are furnished with numerous coarse bristly hairs on the inner side towards their extremity, some 
of them being of a spinous nature, strongly and regularly bent, and forming a longitudinal row on the 
upperside of the rest ; beneath these hairs is a row of five or six minute teeth ; and there is a single strong 
prominent sharp tooth on the underside near the articulation of the fang. 
The mazille are furnished with numerous prominent coarse hairs near their extremity on the inner side.

HERSILIA, Savigny. 
Hersilia mexicana, sp. n. 
Adult female, length 34 lines ; adult male, length 23 lines. 
In general form and appearance this spider nearly resembles the type species (H. caudata ,Aud.: in Sav. 
‘Egypte,’ t. 1. fig. 8). 
The cephalothorax of the female is of a dark yellowish-brown colour, with a lateral longitudinal band of whitish 
hairs on each side some little way above the margin, and a short longitudinal more or less distinct 
yellow line divides the upperside of the caput. The very small caput is prominent, or rather the normal 
indentations showing the junction with the thorax are large and deep. The clypeus projects considerably 
at its lower margin, and its height is more than half that of the facial space. 
The eyes are of moderate size, subequal, placed in two curved rows (whose convex sides are directed forwards) 
on the front or face of the caput, the lower row being much the most strongly curved. The four central 
eyes form a quadrangle whose opposite sides are equal, but its length is greater than its breadth, and the 
lower pair of eyes are a trifle larger than the others. The eyes of the posterior (or upper) row are 
equally divided from each other; and the lateral eye (on each side) of the anterior (or lower) row is 
halfway between the hind-lateral and fore-central eyes, though rather outside of their direct line, and 
appears to be the smallest of the eight. 
The legs are very long, slender, 1, 2, 4, 3, those of the third pair being very much the shortest. They are
