Obs. —This insect is probably identical with the Helops a corselet 
sillonne of Boisduval, in the Voyage de TAstrolable Col. pi. 7, fig. 5, 
but the figures in that work are so execrable, that it is impossible 
to determine the species with precision. 
Obs. —The four genera above described belong to the great family 
Helopidse, and are here published with the view of affording materials 
towards a revision of that group. 
The plant figured in the plate is Australian Epacris nivalis.
