No. 2.] SPIDEBS OF THE MARPTUSA GROUP. 139 



nearly twice as long as the labium and are truncated. The 

 sternum is rather large and wide. 



We have two males, one of which is much darker than 

 the other. The general color of the cephalothorax is dark 

 bronze-brown. There are narrow bands of white hairs on the 

 upper sides, extending below the eyes on to the thorax, as in 

 several other species of this genus. The scaly region on the 

 anterior part of the head is reddish-gold in the lighter 

 specimen; in the other it is of the same color as the rest of the 

 cephalothorax, but is slightlj' iridescent. In both specimens 

 two, indistinct, dark spots are visiljle in the middle of the eye 

 region. The clypeus has a fringe of snow-white hairs. The 

 falces, palpi and first and second pairs of legs are medium 

 brown ; the third and fourth pairs are much lighter, the femoral 

 joints being slightly darkened. The abdomen has two pairs of 

 dark spots on the anterior half and two larger central spots on 

 the posterior, with one or two dark bands or lines near the 

 spinnerets. In some cases the spots on the anterior half are 

 joined together, so that there are four large spots on the dorsum. 

 A line of white hairs extends around the anterior end and half- 

 way on to the sides, and the posterior half has an oblique white 

 bar on each side. The spaces between the spots seem to have 

 l)een entirely covered with snow-white hairs, but these are al- 

 most entirely rubbed off, showing the light brown integument. 



The coloring of the female is substantially like that of the 

 male, though all the tints are lighter. In some of the males 

 the legs and palpi are very dark brown. In others, as in the 

 female, they are bright golden-brown. 



AVe have several males and females from Rio de Janeiro, 

 in the Smith collection.
