416 J. H, Emerton — Canadian Spiders, 



Xysticus triangulosus, new sp. 



The female is 7"'™ long. Cephalothorax S™"" long and S™"' wide. 

 The general color in alcohol is light orange brown with very fine 

 darker spots. The cephalothorax is light in the middle for one- 

 third its width and darker at the sides, the dark stripes ending be- 

 hind under the front of the abdomen in still darker spots. The 

 lateral e3^es are surrounded by lighter color above and darker below. 

 The first and second legs have the femur and patella darker above 

 Avith a light middle line, the ends of the legs being uniform in color. 

 The third and fourth femora are darker toward the end, the fourth 

 femur having a large dark spot at the tip. The other joints of the 

 third and fourth legs are lighter than the first and second and have 

 the ends darker. The abdomen has a light stripe in the middle 

 formed by a row of four triangular spots, widest behind and having 

 the corners extended into three pairs of white transverse spots, 

 behind each of which the dark color of the sides is still darker 

 (PI. IT, fig. 4), as in limhatus and stoinachosus. 



The colors of the male are the same as of the female. It meas- 

 ures 6"°^^ in length. The cephalothorax is nearly as large as that of 

 the female and the first and second leg-s are a little lono-er and more 

 slender. The male palpi as in PI. iv, fig. 4. 



Male and female, near Laggan. 



Xysticus bimaculatus, new sp. 



Length, 5™". Cephalothorax as wide as long. Cephalothorax 

 light brown at the sides, the middle area in some spiders the same 

 color, slightly lighter, or in others almost white Avith a dark spot at the 

 end of the dorsal groove. At the posterior end of the dark areas 

 are two long dark brown spots (PI. iv, fig. 5), which show no trace 

 of division into two as in many species. The legs are light yellow 

 with large brown spots, those on the upper side arranged in two 

 lines and the rest evenly scattered. The fourth leg has larger dark 

 spots at the end of the femur, patella, and tibia, but otherwise the 

 third and fourth legs differ little from the first and second. The 

 abdomen is white with obscure markings. In the most distinct 

 specimen (fig. 5) they form four transverse gray stripes across the 

 hinder half and irregular rows of spots in front. The under side of 

 the abdomen is covered Avith fine spots and the legs Avith large spots 

 on the under side as they are above. The sternum is spotted in the 

 same way. The epigynum is oval, wider than long, and with a
