On HucalyjJtus globulus, an introduced species from Tas- 

 mania, in the streets of Perth. From the discussion which 

 lias arisen concerning the supposed variety of A. perniciosus 

 upon Eucalypti in several of the colonies, it would appear 

 that I have been in too much haste in attaching this species 

 to perniciosus, and was perhaps ill-advised in selecting 

 eucalypti as the name for it. The Victorian species is 

 now, according to Froggatt, A. eucalypti, var. comaius, 

 Maskell, but the Western Australian form is undoubtedly 

 distinct, both in the arrangement of the lobes and in 

 the absence of the transverse groove upon which, in both 

 type and variety, Maskell lays so much stress. It is iu 

 fact a very close relation to A. perniciosus and differs chiefly 

 in the presence of the chitinised prolongation of the 

 margins, and also in the more seri'ated plates, which I find 

 are more pronounced in the second stage female than in 

 the adult.
