Leptobunus borealis (L. bo-re-a'lis). — The apices of the coxae 

 are dark; the tibia of the first legs is marked with one dark band; 

 the palpus is lineate with brown. Occurs in Alaska. 



Leptobunus californicus (L. cal-i-for'ni-cus). — The apices 

 of the coxae are pale; the tibia of the first legs is marked with two 

 dark bands; and the palpus is not lineate. Occurs in California. 



Genus EURYBUNUS (Eu-ry-bu'nus) 



The eye-tubercle is very low and smooth; the cephalothorax 

 with an elevation on the anterior margin bearing a few small 

 spines. The segments of the dorsal shield of the abdomen are 

 so closely united that their sutures are hardly discernible. The 

 femora, patellae, and tibiae of the first and third legs are enlarged; 

 the femur of the second legs is barely twice as long as that of the 

 first legs, and a little longer than the body; the metatarsus of 

 the first legs is without false articulations. 



Eurybunus brunneus (E. brun'ne-us). — The body is very 

 smooth; the fourth leg is nearly as long as the second. Occurs 

 in California. 



Eurybunus spinosus (E. spi-no'sus). — The body is armed with 

 transverse rows of spinules; the fourth leg is much shorter than 

 the second. Occurs in California. 



Eurybunus formosus (E. for-mo'sus). — This is a beautiful 

 species, which occurs in Texas. The dorsum is a rich dark brown, 

 with a medium elongate white spot near the tip; the sides just 

 behind the legs are also white, and the legs are ringed with white. 

 The length of the body is nearly one third inch. 



Genus TRACHYRH1NUS (Trach-y-rhi'nus) 



The inner margin of the patella of the pedipalps is extended 

 at the tip into a spur-like prolongation; the body is very hard and 

 rough; the eye-tubercle is spinose; and the coxae of the third and 

 fourth legs are enlarged in the males. 



Tracbyrbinus favosus (T. fa-vo'sus). — The body is very hard; 

 the dorsum is nearly square, quite level, has projecting angles on
