liave, on the cephalothorax, a wide band of white, low down on 

 each side, beginning opposite the dorsal eye and extending to^ 

 the point at which the abdomen overlaps the cephalothorax,, 

 and a white spot between the dorsal eyes. The one without 

 the green scales has no marks nor spots on the abdomen, but. 

 the others have a band around the anterior part and two or 

 three oblique bands on each side, which are white or yellowish 

 white, while on the dorsum on each side of the middle, is a 

 longitudinal narrow velvety black band, and on these bands 

 are four pairs of snow-white dots. The legs and palpi are 

 somewhat iridescent and are almost black, excepting in one 

 specimen in which the palpi and the patelke are reddish 

 brown. The first pair has a fringe of black hairs on the inner 

 side. Two of our three females are. much lighter colored than 

 the males, being of a medium brown, but the cephalothorax 

 and abdomen have the same spots and markings that are seen 

 in the male, and one of them has patches of the brilliant green 

 scales. The falces are reddish brown above, and iridescent 

 green near the fang. Tire legs are medium brown, but the 

 femora are darkened and the tibia of the first is much enlarged 

 and dark colored, with some dark hairs on the inner side. The 

 third female differs from the others in being as dark as the 

 male, and in having the falces entirely dark red and iridescent, 

 with some white scales on the upper part. 



We have this species from the eastern part of Guatemala, 

 and also in the Snrith Collection from Para and the Amazon.

Spiders above medium size. 



Tlie cephalothorax is rather high and a little longer in 

 proportion to its width than in Phidippus and Parnsenus, having 

 less of the rounded appearance that distinguishes those genera. 

 The cephalic plate is inclined forward. The thoracic part falls 

 from the dorsal eyes, very gradually in the first half and then 

 more steeply. In the male tlie change from the gradual to the 

 steeper sloj)e is more abrupt than in the female. The sides are
