DENDRYPHANTES LtETABILIS, SP. NOV. 



Plate IV, figs. 6-6b. 



^ . Length, 6. Length of cephalothorax, 2.5 ; width of 

 cephalothorax, 2. 

 Legs, 1482 ; first pair much the longest and stoutest- 

 Abdomen iridescent, encircled by a white band. 



The cephalothorax is high and convex, falling directly 

 behind the dorsal eyes, the slope becoming steeper after the 

 first third of the thoracic part. It is rounded on the sides, 

 though not so much so as in niiidus. The cephalic part oc- 

 cupies nearly one-half of the cephalothorax. The clypeus is 

 only one-fifth as high as the anterior middle eyes. The falces 

 are oblique and heavy, with two long stout teeth on the lower 

 side. The fang is as long as the falx. The middle eyes of 

 the first row are nearly twice as large as the lateral. The 

 palpus is long and slender. 



Our single specimen has been badly rubbed. Under al- 

 cohol it is black, with two patches of white hairs on each 

 side of the cephalic part, one in front of the dorsal and one 

 in front of the small lateral eyes, and with a white band 

 encircling the abdomen. When dry, patches of brilliant iri- 

 descent scales appear on the cephalic plate and on the central 

 part of the abdomen. The falces, palpi and first legs are 

 dark bronze brown. The other legs are lighter brown, varied 

 with yellowish, the proximal ends of the femoral joints being 

 yellow. The sides of the face below the lateral eyes are cov- 

 ered with short white hairs. 



We have a single male from Panama, sent to us by 

 Count Keyserling.
