The chief variation in tliiis .species is in the scaling of the 

 female palpi. These are always tipped with ochreous white, 

 but have a variable number of ochieous scales scattered over 

 the upper surface. The differences do not seem to me to be 

 of specific value.

Strickland's species only differ in very slight characters 

 (chiefly the colour of tl'ie thoracic integument), and it is 

 impossible to regard them as distinct. The species is no 

 doubt correctly identified as G. occidentalis, Skuse.
