third much shorter, and a little thicker, than tibia of the fourth; 

 patella (alone) longer than patelli of the fourth; tarsus and meta- 

 tarsus of the fourth as long or scarcely shorter than patella and 

 tibia; tibia of the fourth, slightly enlarged at the extremity and a

Eyes of the first row as in Euophrys. The eyes of the third row plainly 



smaller than the outer eyes of the first row, and further removed 



from them, the eyes of the seconi row very small, nearer to the 



outer eyes of the first ro v than to the eyes of the third row. 



Falces in the male large, convex, smooth, twice as long as the face; in the 



female smaller. 

 Palpus without distinctive characteristic. 



This genus stands very near to the genu? Euophrys, but the position of 

 the eyes and the large falces separate it essentially. Moreover thecephalo- 

 thorax and abdomen are thinner, that is to say narrower and longer, and 

 also are covered cl )sely w^ith shining scales, which give the color and 

 marking. The female palpus has nothing uuusual; that of the male I 

 know only from young animals with immature bulbs; these are not dif- 

 ferent from those of Euophrys.

K^ephalothorax one-third or one-fourth longer than wide, sensibly con- 

 tracted toward the front, behind rounded, wider at the dorsal eyes, 

 rather low, slightly convex above. 



•Clypeus low. 



'Quadrangle of Eyes, wider than long, in front moderately contracted, not 

 reaching the middle of the cephalothorax. First row of eyes curved 

 upward; the lateral are separated by half their own diameter from 

 the large eyes. Dorsal eyes are further from one another toan fi'om 

 the margin of the cephalothorax, small median eyes are half way 

 between the lateral anterior and the dorsal eyes. 



Falces short. 



Maxillae dilated and rounded in front. 



Hypohlemum is substituted for Z);•epa?^ep/l.o(■a, the lattername being preoccupied.
