second pairs of legs are plainly shorter and stouter than the 

 third and fourth. The first row of eyes is a little curved. 



The cephalothorax is covered with bright red hair, which 

 stands out around the eyes of the first row. On the central 

 thoracic part, just where it begins to slope backward, is a dark 

 brown chevron, which points forward. The abdomen has a 

 mottled appearance, from being thickly covered with a mixture 

 of red, white and a few black hairs. The upper four spinnerets 

 are short and close together. The lower four are longer, and 

 the external one on each side is covered with white and red 

 hairs. Underneath, the venter is mottled with black and white. 

 The legs, palpi, sternum and mouth parts are light reddish- 

 yellow ; the falces are darker. 



We have one female, in the Smith collection, from Brazil 

 (Santarem).

This species is much like cruenta. The first row of eyes, 

 however, is straight. The middle eyes are prominent and 

 large, the lateral being placed further back. The falces are 

 vertical, and moderately long and stout. 



The spider has been dried and shriveled so that no very 

 exact description is possible. The general color is medium 

 brown, more or less blotched and spotted with black. The in- 

 tegument, in the eye region, is of a yellowish color, and there 

 are some yellow hairs remaining around the eyes of the second 

 and third rows. The hairs on the clypeus are white. The 

 abdomen is dull brown, with speckles of black, and a broken 

 white band down the middle, which is made neither of scales 

 nor of hairs, but apparently of a thickened part of the integu- 

 ment. The drawing gives the spider as it appears under al- 

 cohol. The palpi are pale yellowish, with white hairs. The
