Other joints light and black at the ends. The under side is 

 black. The sternum is very short, so that the basal joints of 

 the front legs touch each other. 



Hasarius ho3ri. — This species may be known by its peculiar 

 colors, — the dark portions brown or black and the light parts 

 white and orange brown (figs. i6i, 162). These colors are, as 

 usual, brighter and the markings more distinct in the males. 

 In front around the eyes the cephalothorax is covered with 

 white hairs. At the sides a white band extends backward 

 under the eyes, turning inward but not reaching the middle 

 line. There is a light band, part white and part orange, 

 around the abdomen and several angular marks in the 

 middle, two of them in the hinder half, sometimes 

 united into a large spot. In alcohol, and less 

 plainly seen when alive, is a light band under 

 the hairs, extending across the mid-

 on the sides under the eyes. 



In females all these markings are 

 less distinct, but traces of them can 

 be found in most individuals. The 

 colors are more brownish, and the 

 markings of the abdomen smaller 

 and more uniform in shape. The 

 markings of the legs are dark on 

 the middle joints and light at the 

 base and on the tarsi, with strong 

 contrasts in color in the males and'
