No. 2.] SPIDERS OF THE MARPTUSA GROUP. 123 



.and tibia of the first leg, especiallj' the tibia, are very stout and 

 have a glistening iridescent appearance. The tibia has two 

 rows of stout spines, which are continued on the metatarsus. 



The cephalothorax is reddish-brown with a golden tinge ; 

 there is some light yellow hair around the eyes, and just be- 

 hind the first row is a pair of small black spots. There is a 

 black line around the lower margin. The abdomen is light 

 brown, with some darker spots along the sides and two faint 

 dark lines down the middle. In the center of each of the pos- 

 terior four spots is a white dot, and as there are some white 

 hairs left on the other spots and on the dark lines, it is prob- 

 able that they were originally entirely covered with them. 

 The legs of the first pair are brown, the femur and tibia being 

 darker than the other joints and iridescent. The other legs 

 are light yellow. 



This species has the first leg much like that of Taczanow- 

 ski's Chirothecia wrzesniowski, but there is no bunch of hairs 

 on the tibia. We have one female from Santarem, Brazil. 



HOLOPLATYS SIMON. 

 Plate XII., Figs. 6—6/;. 



Spiders extremely flat, but not very slender, of medium 

 :size or larger. General appearance heavier than Rudra. 



The cephalothorax is very low and flat, the cephalic and 

 thoracic parts being on the same plane. It is nearly twice as 

 long as wide. The sides are almost parallel, there being a 

 slight enlargement behind the dorsal eyes. 



The quadrangle of the eyes is one-fourth wider than long, 

 is equally wide in front and behind and occupies a little less 

 than one-third of the cephalothorax. The first row of eyes is 

 straight ; the eyes are close together, and the middle are fully 

 twice as large as the lateral. The second row of eyes is slightly 

 nearer the first than the third. The third row is nearly as 

 wide as the cephalothorax at that place. 



Holoplatys is nearest to Rudra, but the cephalothorax is 

 -even flatter, and both the quadrangle of the eyes and the
