Liobunum 



To tliis genus belongs the c.\ccs>ively long-legge<i forms. Many species 

 are known from the eastern L'nited States, and from Kurope, but only two 

 are so far recorded from the West Coast, one of these, however, is very 

 common. 

 1. Two large yellow spots over the junction of tiie cephalothora.x and 



abdomen bimncuhitum. 



No large yellow spots on junction of the ccphalothorax ant! abdomen 



Liobunum exilipes WOod 

 .\dult males arc dark brown, with sonic scattered small pale sjjots, a larger 

 ])ale spot in front of the cye-tubcrclc, and the palpus, except the tarsus, is 

 black. The female is paler, and, when mature, shows a dark vase mark on the 

 dorsum. Young arc pale, mottled with brown and black. In both sexes the 

 trochanters are darker than the coxs, and the tips of the femora and tibiic 

 are more or less distinctly paler than the rest of the joint. Specimens have 

 been examined from Mt. Shasta, Santa Clara County, Los .Angeles, Clare- 

 mont, Santa Rosa Island, and it also occurs in Washington State. 



Liobunum bimaculatum Bks. 

 This species has still longer legs than /.. exilipes; it is dark brown in clor. 

 with two prominent yellow spots, and the trochanters are no darker than 

 the coxae. I have seen it only from near San Diego.
