the patella, black on the tibia, white at the proximal and black 

 at the distal ends of the metatarsus and tarsus. The f alces are 

 iridescent green. 



This may very possibly be the female of Phidippus varlega- 

 ius. We have several specimens from Texas. 



Phidippus Tyrellii, sp. nov. 

 PI. XXIV, fig. 4. 



A medium sized species, with bands of white hairs along the 

 outer edges of the falces. 



5. Length 9 mm. Length of cephalothorax, 4.5 mm.; 

 width, 3 mm. 



Legs 1423; first leg a little longer than the body; second leg 

 scarcelv longer than the third. 



The cephalothorax is black, with wide white bands on the 

 sides and above the first row of eyes. Overhanging these eyes, 

 below them on the clypeus, and hanging do^vn between the 

 falces, are some long, Avhitey-brown hairs. The cephalic plate 

 is covered with short brown hairs. The falces are iridescent 

 green, with a streak of snow-white hairs along the outer edge, 

 ending at the insertion of the fang. The abdomen, in our speci- 

 men, is badly rubbed, and shows only a low band of white 

 around the anterior end, and behind this a good many bright 

 red hairs which probably covered the dorsal surface. Under 

 alcohol some pale markings appear, a large, central, triangular 

 spot, posterior to this, two pairs of transverse bars, and, be- 

 tween these, a central spot, all of which were very probably cov- 

 ered with white hairs. The legs are very dark, almost black. 

 The first is the stoutest, and is fringed, the hairs being colored 

 as follows : on the upper surface of the femur they are dark ; 

 on the inner face they form transverse bars of white at the ex- 

 tremities, with an oblique black band between ; on the outer 

 face there is a white fringe along the lower edge, overhung by 

 some darker hairs ; on the patella and the proximal end of the 



tibia they are white, while on the distal end of the tibia they are 

 inky black, and grow very thick, both above and below. Both 

 metatarsus and tarsus have the proximal ends covered with 

 white and the distal ends with black hairs.
