brown on a paler yellowish-brown ground ; three of these patches, 

 or spaces, are nearly contiguous in the median line, a large one in 

 front and two smaller ones immediately behind ; some small tufts 

 of white hairs also occupy the sides, hinder portion, and other 

 parts of the abdomen ; the upperside generally is sparingly 

 covered with very minute white hairs ; the sides and hind portion 

 are yellow-brown, irregularly marked and mottled with black- 

 brown ; legs brownish, banded with yellow ; spines on the under- 

 sides of femora longer and more slender than in T. dubitmi. 



A single female of this species is in the Hope Collection, 

 University Museum, Oxford, received from New Holland.
