From Whittier, California; on lemon leaves; by Mr. Netils. The 

 type specimen from Neiils shows the sperm sac attached to the tip of 

 the chelicerae. In the Gamasidce, the male transfers the sperm from 

 his genital orifice to the vulva of the female in a hyaline sac by means 

 of the chelicerae. The various modifications of the chelicerae are fre- 

 quently adaptations for this method of fertilization.
