 tlian tlie thorax. Mandibles half as long as the cephalothorax with 

 two very short teeth above the claw and none below it. Eig. 4. 

 PI. III. The male palpi have a wide and flat process of the tibia 

 extending a third its length over the tarsus on the outer side.

Cephalothorax 2 mm. long. Abdomen of male 2 mm. Abdomen 

 of female 3 mm. or more. The cephalothorax is orange yellow, 

 darker in males, and in both sexes with a distinct black patch 

 around the eyes and backward about a quarter the length of the 

 cephalothorax. In the females the abdomen has three light stripes 

 varying in length and width. Fig. 3. PI. III. In the male there 

 are usually no stripes. In both the sexes the ends of the abdomen 

 are darker than the middle, sometimes forming a definite pair of 

 black spots at each end. The legs are orange yellow without any 

 markings. The middle eyes are less than their diameter apart, 

 but not as close as in S. keyserlingi. 



In the male the second tibia is slightly thicker than the first 

 and the spines on the inner side are thickened and short, not much 

 over half the diameter of the tibia. On the first tibia the spines 

 on the inner side are somewhat thickened and about as long as 

 the diameter of the tibia. Fig. 36. PI. III. Kenora, Edmonton,

Pardosa albiceps. new sp.
