males the front row eyes are equal and equidistant, about half 

 their diameter apart, the median less than their diameter from 

 the rear median. 



The abdomen is bright yellow-brown above, with fine darker 

 hair, sometimes forming a scolloped or ti-ansversely barred pattern ; 

 four pairs of muscle-spots not very clearly defined. The median 

 pairs sometimes conjoined by a dark line. 



It ranges over the southern half of the continent.

This is the northern form of the above, and, although Dr. Karsch 

 quotes it from South and West Australia, out of a considerable 

 number of specimens I have not myself seen one of /. immanis 

 from the South, nor of /. insignis from the North of Australia. 

 This form has a very characteristic dark stripe on the back of the 

 abdomen, reaching from the front two-thirds of the distance to 

 the rear. In other respects the two species difi'er very little.
