Unless expressly stated to the contrary, specimens of all the 
mew species have been taken by myself, and the localities (and 
food-plants where given) may be depended upon. 
DESIANTHA MALEVOLENS, 7. Sp. 
Piceous, legs and antenne piceous- red. Upper - surface 
moderately closely covered with obscure ochreous and brown 
scales, the ochreous scales clothing sides of prothorax, and forming 
a distinct median line; scutellum with greyish scales; elytra 
with a wide dark sutural patch, the sides with paler scales, 
extreme margins with greyish and sooty-brown scales ; a small 
distinct suboblong whitish spot on each elytron just before 
summit of posterior declivity. Under-surface and legs densely 
clothed with ashen scales, in which a few short stout pale setz 
are mixed. 
Head and rostrum densely punctate; a feeble depression 
between eyes. Rostrum arcuate, stout, rather short. Club 
elongate. Prothorax transverse, sides and base rounded, apex 
widely emarginate, and almost the width of base. lytra widely 
emarginate at base, apex conjointly rounded, shoulders oblique ; 
punctate-striate, punctures concealed ; interstices feebly convex, 
wide, and regular. Under-surface densely punctate, punctures 
concealed. Prosternum feebly and widely emarginate in front. 
Intermediate intercoxal process descending at an angle of about 
45°. Metasternum depressed in middle, the depression continued 
on to abdomen. Two basal segments of abdomen very large, 
third and fourth very short (their combined length being only 
about half that of the second or fifth), and arcuate at sides. Legs 
rather long ; femora thick, subpedunculate; tibie falcate (the 
anterior very decidedly so), with numerous small teeth beneath ; 
apex thin, terminal hook unusually long and sharp ; tarsi with 
fourth joint shorter than the rest combined. Length (from apex 
of prothorax), 43 mm.; rostrum, 1] mm.; width, 2 mm. 
Hab.—Swan River (Hon. J. G. H. Amherst). 
This species, in the characters of its rostrum, abdomen, tibiz, 
and tarsi, is somewhat at variance with the majority of species 
in Desiantha ; and it may be eventually considered necessary to 
erect a new genus to receive both it and the following species ; 
but as the genera closely allied to Desiantha are already so 
numerous, and some of them are founded on such trivial charac- 
ters, I am strongly adverse at present to adding to their number. 
The species is reported to be very destructive to the young shoots 
of the vine, its work being much the same as that of D. maculata. 
DESIANTHA VEGRANDIS, 7”. sp. 
Piceous, legs and antenne piceous-red. Upper-surface closely 
covered with muddy-brown scales, prothorax with the sides and
