Show 1902.] MR. H. R. HOGG ON AUSTRALASIAN SPIDERS. 433 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 transversely barred pattern; tour 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. The following measurements in millimetres are from South Australian specimens:- Female. Long.

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 I. immanis from the South, nor of I. insiynis 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 differ very little.
