Another Record of a Small Whip 

 Scorpion in California 



M. L. MOLES 



In April, 1916, Dr. VV. A. Hilton collected some small whip- 

 scorpions in the Pomona College Park at Claremont. These creat- 

 ures were without eyes and yet they seemed to avoid forceps. They 

 were able to run backwards or forwards with equal ease. On 

 examination it was found that there were long hairs on the legs 

 such as shown in the figure. Other specimens were afterwards 

 found in one of the nearby canyons, and two specimens in the college 

 collection were marked "C. Met/, in the mountains near Clare- 

 mont." 



Upon looking through the literature the species was determined 

 to be Tritliyreits pentapeltis Cook. In 1899 Dr. Hubbard col- 

 lected some at Palm Springs under stones in the canyon near the 

 stream. Those which we ha\e found this year were under the 

 dried oak lea\es some distance from water. Cook gave the generic 

 name Hiibbardia which has not been sustained.

 or more specimens found.
