I can see no structural differences heivieen variabilis., Sm., 

 and raptor, Sm., in the male sex, but have not been able to 

 examine the genitalia. At one time I thought they might 

 prove to be local races o£ one species, but I have since taken 

 both forms on the same day in King's Park, Perth. The 

 male variabilis has the abdominal fasciae interrupted and the 

 basal joint of the anterior tarsus bordered with black on the 

 outer edge ; the thoracic markings are also less developed 

 than in raptor. These colour-differences also exist in the 

 female, in which sex also the second ventral segment is 

 more sparsely punctured in raptor than in variabilis and the 

 sixth dorsal segment slightly broader in varialjilis.

This seems to be the commonest form in Central Australia. 

 Handlirsch seems to include it in his description of the very 

 closely related variabilis.
