I have no doubt of the stability of both the above species, semi- 
nigrum and Fryw; nevertheless they are closely allied. It would be 
very interesting if Mr. Diggles, or some other naturalist in Queens- 
land, would kindly examine the question, and note so far as is possi- 
ble the food plant of the species. Queensland is in a sufficiently 
northern latitude to lead us to expect that several species of this 
handsome group may be discovered there. 
I have an example in my cabinet from the collection of the Marquis 
La Ferté, labelled “ New Holland.’’*

So brief are the descriptions that have been published of exponents 
of this genus by authors, that in the absence of typical specimens it is 
doubtful whether any species has been previously recorded. Blanchard, 
in the ‘ Voy. au Pole sud,’ has described a species, A. limbatum, from 
New Guinea which is very nearly related to A. cinctum of Baly, de- 
scribed in this Journal; it is probable that as there is a difference in 
the breadth of the flavous margination of the elytra, other differences 
may arise which will prove the two to be distinct ; at any rate the 
species before us is abundantly different from A. cinctum. By the 
kindness of my friend Mr. Baly I possess a type specimen of this 
species: it is broader, more distinctly punctate, the flavous margin 
extends to the apex, the last segment of the black abdomen is fus- 
cous; the coloration also differs in hue from the species before us. 
I possess two examples of this insect—one, from the La Ferté col- 
lection, from the island Woodlark, the other, from Damel’s collection, 
from New South Wales—showing that the species has, like some of 
its congeners, an extensive range of habitat.
