Thyene Ogdenii sp. nov. 
Plate XXV, figs. 2-2 d. 
Length, 3 7 mm, ? 8 mm. Legs, 3 1342, ? 3412, first and 
second pairs stoutest. 
The quadrangle of the eyes is wider behind than in front 
and the middle eyes of the first row are fully twice as large 
as the lateral, which are separated from them. This row is 
straight. The third row is narrower than the cephalothorax. 
In the male the cephalothorax is brown with a transverse 
patch of yellowish hairs just above the eyes of the first row. 
These eyes are surrounded by reddish hairs.. There is also, 
just below the lateral eyes, on the sides, a narrow band of yel¬ 
lowish hairs., and a median longitudinal band of the same 
color passes backward from between the dorsal eyes., but does 
not reach the lower border. There * are bunches of scattered 
hairs just behind the lateral eyes. The first legs are darker 
in some specimens than, in others, varying from yellowish-brown 
to blackish-yellow. The femur is light above, and dark below, 
with transverse dark bands in front. The tarsi are lighter than 
the other joints. The second leg is lighter colored than the 
first, the femur being light above and dark below, and the rest 
light yellow. The other legs are yellow. In some specimens 
the tarsi and metatarsi of the three posterior pairs are white. 
The abdomen has the sides brown, deeper in front than behind. 
There is a median longitudinal yellowish-golden band—the an¬ 
terior half being more yellowish, and the posterior more golden. 
On either side of this band is a narrow reddish line. In the 
posterior half, in the reddish line, are three pairs of small white 
spots. So<m|e specimens have the brown color on the sides 
tending to break up into large spots. Low down on the pos¬ 
terior sides are some oblique white bands. The falces are dark 
brown, moderately long and stout, and slightly projecting. 
In the female, of which we have only rubbed specimens, the 
cephalothorax is yellow. Above the first row of eyes, the 
whole cephalic plate seems to have been covered with golden- 
yellow hairs, the first eyes being surrounded by lighter yellow
