DENDRYPHANTES DUBITABILIS, SP. NOV. 



Plate IV' figs. 7-7a. 



9 . Length, 5.9. Length of cephalothorax, 2.2 ; width of 

 cephalolhorax, 1.5. 

 Legs, 4123 ; those of the first pair plainly the stoutest. 



The cephalothorax is high, and is widest at and just 

 behind the dorsal eyes. The sides are vertical in the cepha- 

 lic part, but broaden out a little at the lower edge, in the 

 thoracic. The cephalic part is inclined. The thoracic falls 

 from the dorsal eyes, gradually in the first third, and then 

 more steeply. The quadrangle of the eyes is plainly wider 

 behind than in front, and at its widest point is one-fourth 

 wider than long. It occupies nearly one-half of the cephalo- 

 thorax. The anterior eyes are not very large. They are a 

 little separated and form a straight row, the middle being 

 nearly twice as large as the lateral. The second row is nearer 

 the first than the third. The third row is scarcely narrower 

 than the cephalothorax. The falces are vertical, and moder- 

 ately stout and long. The clypeus is one-third as high as the 

 large middle eyes. The first legs are considerably stouter than 

 the others. 



Our specimens have been badly rubbed. The cephalo- 

 thorax is black with a narrow band of white hairs around the 

 lower margin, and patches of white and of iridescent hairs. The 

 abdomen is brown or black, covered with hairs of a bright gold- 

 en yellow color. There is a white band around the anterior 

 end, a pair of white spots on the anterior part, and two trans- 

 verse white bands on each side, behind the middle, which curve 

 upward from the sides. The legs are dark brown, more or less 

 banded with a lighter shade. The palpus is brown with white 

 hairs. 



We have a female and an immature male from Tahia, 

 Mexico, sent us by Mr. Townsend. 



Although this species agrees fairly well with the genus
