SYN AMA.—MISUMENA. 85 
The abdomen is large, broader behind than in front, where it is well rounded ; the upperside is very convex. 
It is of a pale luteous colour, closely freckled above with white cretaceous spots; near the middle of the 
upperside is a large curvilinear chevron or circumflex-accent marking of a dark brown colour, the angle 
directed forwards; this is followed towards the spinners by three other much smaller and less conspicuous 
markings, The underside is yellow-brown, darkest along the middle, the spinners dark yellow-brown. 
Genital aperture small and very inconspicuous, but of characteristic form.

DLA, Thorell. 
Diza puta, sp. n. 
Adult female, length 2% lines. 
The whole of the anterior portion of this spider is of a pale yellow colour. 
The eyes are on greyish tubercles, compactly placed in the form of a crescent. The anterior row is much 
the shortest. The fore central pair are smallest, and separated from each other by two diameters’ interval, 
but are nearer than that to the laterals. The fore laterals are considerably the largest. The intervals 
between those of the posterior row are equal. The four central eyes form a square whose anterior side 
is distinctly shorter than the others. The clypeus is less than half the facial space in height; it has two 
spine-like bristles projecting forwards, with converging points in the middle close to its lower margin. 
The legs are short, 1, 2, 4, 3, and rather strong. Those of the first and second pairs do not much exceed the 
length of the spider, and are very nearly equal in length. The tibie are armed beneath with four, and 
the metatarsi with three, pairs of strong spines, besides a few others of very small size. The two posterior 
pairs are much the shortest, and have a few fine spines only. 
The falces are short, strong, vertical, and conical in form. 
The labium is short-oval. It is of a pale luteous colour, thickly mottled with cretaceous white spots. The 
genital aperture is very characteristic; in form it is somewhat kidney-shaped.

MISUMENA, Latreille. 
Misumena pascalis, sp. un. 
Adult female, length 3 lines. 
The cephalothorax is yellowish-brown, with two broad bright red-brown parallel bands—one on each side of the 
caput, ending just beyond the thoracic slope; at the middle in front of the thoracic junction, between 
these two bands, is a conspicuous X-shaped yellow-white marking. 
The eyes are very small; the fore laterals slightly the largest. All are on greyish-yellow tubercles, those of 
the lateral pairs the strongest. The four central eyes form a square whose anterior side is the shortest. 
Taken in two transverse rows the eyes of each row are equally separated from each other. The height of 
the clypeus is equal to half that of the facial space. 
The falces are rather small, nearly vertical, conical, and similar in colour to the cephalothorax. 
The legs are short, moderately strong, 1, 2, 4, 3. Their colour is dull orange-yellow. Those of the first and 
second pairs have the femora marked with two longitudinal broadish white bands underneath, and an 
obscure whitish line along the upperside of the tibiew. The extremities of the genua and tibie are suffused 
with rusty-brown, but scarcely amounting to annulation. Beneath the metatarsi are four, and beneath 
the tibize six, pairs of spines, but not very strong ones; there are also four spines on the upperside of the 
femora of the first pair—three in a longitudinal row and one behind. The spines on the two hinder pairs, 
which are paler in colour than the others, are very small and irregularly disposed. 
The abdomen is large, of a subpentagonal form, much the broadest behind, the angles rounded. It.is thickly 
covered with white cretaceous spots, with a broad, deep brown band round the fore half of the upperside, 
narrowest in the middle, and a central longitudinal, somewhat oval, patch of deep brown is followed by 
some irregular oblique stripes of brown and black-brown on the hinder half, their obscure extremities
