nearly as long as the tibia and tarsus together. There is a 

 strong apophysis at the distal end of the tibia, on the outer 

 side. 



When dry, the cephalothorax, legs and falces are brown. 

 The eyes are placed on black spots, which, however, are nearly 

 covered with white hairs, patches of which are also seen on the 

 eye-region and in the post-ocular depression. Around the two 

 middle anterior eyes are rings of brilliant red hairs, which 

 grow longer, in the form of tufts, in the spaces above and 

 between the middle and lateral eyes. The abdomen is pale 

 brown, with a brilliant white band down the middle, on either 

 side of which, at the posterior end, are three black spots in a 

 longitudinal row. On each side of the abdomen are three 

 oblique white bands, the posterior two being low down. The 

 palpus is white (without hairs) throughout its length, only the 

 bulb of the tarsus being darkened. 



We have a single male, from the eastern part of Gautemala, 

 which was first described in 1885, in a paper on Gautemala 

 Attidse in the Proceedings of the Natural History Society of 

 Wisconsin. It is redescribed here with more detail because we 

 have since received several other species which resemble it 

 so closely that it is difficult to distinguish them.

This species is of about the same size and coloring as longi- 

 palpus, and also resembles it in having a long white palpus. 

 It differs, however, in the higher clypeus, the larger middle 

 eyes, the vertical falces and in some smaller details. 



The quadrangle of the eyes occupies more than one-half of 

 the cephalothorax, and is nearly equally wide in front and 

 behind. The middle eyes of the first row are about three times
