Mr. Buackwaut's Descriptions of new Species of Spiders. 669 
Length of the female 3ths of an inch; length of cephalo-thorax 355; breadth 
$; breadth of abdomen +; length of an anterior leg 3; length of a leg 
of the third pair 45. 
Anterior part of the cephalo-thorax compressed; sides marked with slight 
furrows diverging from the upper part to the margins; there is a large 
indentation in the medial line of the posterior region ; colour pale brown, 
with black margins, a few transverse, black streaks on the sides, and a 
band of the same hue extending along the middle, and increasing in 
breadth as it approaches the eyes, where it comprises several pale brown 
spots. Eyes disposed in two transverse rows on the anterior part of the 
cephalo-thorax ; the four intermediate ones form a square, and those of 
each lateral pair, which are nearly contiguous, together with the eyes of 
the anterior intermediate pair, are seated on small eminences. Mandi- 
bles powerful, conical, convex in front, armed with two rows of teeth on 
the inner surface, and inclined towards the sternum; their colour is very 
dark brown, tinged with red. Maxillæ straight, enlarged and rounded 
at the extremity, and dark reddish brown. Lip semicircular and brownish 
black, having a faint tinge of red at the tip, which is prominent. Ster- 
num heart-shaped, with prominences on the margins, opposite to the 
insertion of the legs ; its colour is brownish black. Legs and palpi long ; 
their colour is yellowish brown, with black spots and rings; the tarsi are 
‘reddish. First pair of legs the longest, then the second, third pair the 
shortest. Abdomen oviform, thickly covered with hairs, convex above, 
projecting over the base of the cephalo-thorax ; it is mottled with black 
and brown, having an obscure, yellowish, curved line on each side of the 
anterior part, and a broad, dentated, yellow band extending along the 
middle of the upper part; this band, which comprises a fine, longitudinal, 
branched line of a darker hue, is narrowest at its anterior extremity, 
near which a short, yellow line crosses it at right angles; on each side of 
the middle of the under part is a longitudinal, yellow line. Plates of the 
spiracles pale brown. 
The male is smaller than the female, but resembles her in colour, and 
in the relative length of his legs. Third and fourth joints of the palpi 
short ; the latter is the stronger, and has a pointed apophysis at the extre-
