116 PECKHAM. , [Vol. 2, 



In alcohol the abdomen and the second, third and fourth 

 pairs of legs are pale yellow, almost white, while the cephalo- 

 thorax and first pair of legs are much darker yellow, tinged 

 with red. 



The central anterior eyes are reddish-yellow, like the color 

 of the cephalothorax. The other six are black and are placed 

 on large, black spots. There is a good deal of snow-white hair 

 on the cephalothorax, growing most thickly in a band above the 

 anterior eyes, in lateral bands and in a central spot behind the 

 dorsal eyes. The mouth parts and falces are brown, darker in 

 the male than in the female ; otherwise . the under surface is 

 very light yellow — almost white. The first legs are dark red- 

 dish-yellow, with a fringe of dark hairs, intermingled with 

 spines, along the inner edge. The other logs are pale yellow. 

 The palpi are pale yellow, only the distal joint being darkened. 

 The clypeus has a distinct fringe of white hairs. The abdo- 

 men has, on the dorsum, four pairs of white spots, those on 

 the anterior part being separated, while those on the posterior 

 part approach each other and almost coalesce. In one speci- 

 men (the one shown in the drawing) there seems to have been 

 a central white band, although a good deal of it is rubbed away. 

 In another there seem to have been two narrow white bands, 

 separated by a yellow space, down the middle. In all cases the 

 white part consists of flat scales, and the bands or spots are 

 broken by cracks or veinings which show the yellow color of the 

 integument. 



In color and appearance this species is much like Itata isa- 

 bellina of Taczanowski, which is found in Peru. The female of 

 the latter species, however, has the first leg plainlj^ longer than 

 the second, while in vadia they are nearly equal. 



We have two males and three females from New Grenada.

The cephalothorax is long, low, flat and narrow, and is
