Palestrina gen. nov. 



PL XXVI, figs. 4-4c. 



This genus, while in size and general make np it recalls 

 PJiidippus and PJiilaeus, has a different look about the cephalo- 

 thorax. The sides are high, but instead of being rounded off, 

 they fall in a steep, straight slant. The dorsal surface, on the 

 contrary, is more gently rounded than in those genera, the curve 

 of the fall behind the dorsal eyes being just about equal to that 

 in front of them. The sides are narrow in front but bulge out 

 behind the dorsal eyes. The quadrangle of the eyes is one- 

 fourth wider than long, is very slightly wider in front, and oc- 

 cupies two-fifths of the cephalothorax. The first row is very 

 slightly curved and the middle eyes are larger than in the allied 

 genera, being about twice the size of the lateral eyes. The sec- 

 ond row is nearer the first than the third, and the third row is 

 nearly as wide as the cephalothorax. In the species that we 



have of this genus the relative length of the legs is 4312, the 

 third and fourth being plainly longest, and the first and second 

 plainly stoutest. As compared with Servaea Palestrina has the 

 middle eyes of the first row relatively larger, the sides higher 

 and steeper, and the quadrangle of the eyes wider behind. 



Of this genus we have only variegata, a new species from 

 Brazil. 



Palestrina variegata sp. nov. 



PI. XXVI, figs. 4-4c. 



$. Length 9-10 mm. 



Legs 4312, first and second pairs stoutest. The third is 

 longer than the second by the tarsus and half the metatarsus. 



The cephalothorax is entirely covered with bright golden 

 hairs. On the abdomen these gold-colored hairs are mingled 

 with black ones to form a beautiful mottled pattern of spots and 

 short wavy lines, which is very effective in an unusual style. 

 The whole face, and the clypeus are covered with, long yellowush 

 white hairs which run down on to the dark colored, strong, ver- 

 tical falces. The same hairs form a fringe on each side of the
