140 _ ARANEIDEA. 
This genus is nearly allied to Oxyopes, Latr., but whereas the two hind-central eyes 
in that genus are seldom, if ever, further apart than each is from the hind-lateral eye 
of the same row on its side, in the present genus they are always so; sometimes more 
than double the distance, or even nearly three times, thus widening to a great extent 
the two main groups; the two small anterior eyes are also more nearly in a straight 
line, sometimes exactly so, with the two eyes nearest them. 
_ Oxyopeidon facile, sp. n. 
Adult female, length very nearly 4 lines. 
Cephalothoraz dark yellow-brown, clothed in parts (probably in a more perfect specimen entirely 80) with 
white squamose hairs. Clypeus prominent, its height rather exceeding half that of the facial space. 
Eyes on black diffused spots, the lateral eye on each side (at the apex of each of the lateral triangles) seated 
on a tubercle ; the interval between the hind-central eyes (taking the eyes as in two transverse rows) is 
nearly three times that between each and the hind-lateral eye next to it. The two minute anterior eyes 
are, when looked at from in front, in an exact line with the eye on each side of them, and these last are 
the largest of the eight. 
Legs and palpi yellow-brown, paler than the cephalothorax. 
Falces similar in colour to the cephalothorax, and clothed with white squamose hairs, especially towards the 
base. Fang very short, and weak at its extremity. 
Mazxille, labium, and sternum similar to the legs in colour. 
Abdomen dark brown on the upperside, clothed with short reddish and grey squamose hairs; along the middle 
of the fore part is a darker obscure stripe, and there are some black markings above the spinners; the 
sides have each a kind of obscure broken longitudinal stripe or line of patches and spots of yellow-brown, 
some of them more or less confluent, and appearing to be clothed with white hairs longer than the rest ; 
these lines of spots end near the spinners. The underside has a broad, longitudinal, central, black-brown 
band, margined with a brownish-yellow stripe. The spinners are short, compact, and of a dark yellow- 
brown colour. The genital aperture is of simple but characteristic form. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith). 
_ Oxyopeidon putum, sp. n. 
Adult female, length 3 lines; adult male, length 24 lines. 
The specimens examined of this species are all in rather bad condition, being more or less denuded of their 
hairy clothing and pubescence. The general colour is yellow. 
The cephalothorax is tinged with orange-brown, and (where not rubbed) covered with short grey hairs. 
The falces are of a similar colour to the cephalothorax ; the legs, palpi, and sternum paler yellow, and the 
maxille and labium tinged strongly with brown. 
The abdomen is of a dull luteous-yellowish hue, but in some examples with traces of dark reddish-brown 
markings both above and on the sides. The genital aperture is simple, of a characteristically distinct 
form. 
The eyes of the hind-central pair are rather more than double the distance apart that each is from the hind- 
lateral eye on its side; a line drawn between the two minute anterior eyes and the two large ones near 
them would touch the upper edge of the former and the lower edge of the latter. The height of the 
clypeus is equal to half that of the facial space. 
The male shows no trace of any dark markings, and it has the eyes placed on large well-defined black patches ; 
' the two minute anterior eyes are also placed rather higher up than in the female, so that a line drawn to 
touch the lower edge of the two large adjacent eyes would run through the small ones, and the interval 
between the hind-central pair is proportionally rather greater. The falces also are shorter and less 
strong. The palpi are short ; the radial and cubital joints very short, the former with two small apophyses 
rather underneath on the outer side; the digital joint is of tolerable size and short-oval form; the Palpal 
organs are well-developed and complex, but do not present any very marked processes.
