SILPHOMORPHA. 
Stlphomorpha Picta: length 54’ ; resembles entirely Mtidu- 
loides, with the exception of the thorax, which is either 
entirely black, or with two broad longitudinal bands of that 
colour, leaving the middle red. 
This insect is found rather commonly in the northern 
parts of Queensland, at Port Denison, and Rockhampton. 
Of the numerous specimens I have received, not one has 
the thorax entirely red as are the specimens of Mézduloides 
found in Victoria and New South Wales. 
Silphomorphe. Marginata: length 5’; broad, depressed, of 
a shiny black; parts of the mouth, antennz, and the very 
narrow lateral margin of the thorax and elytra brown; the 
latter with a large yellow spot extending to all the length 
of the elytron, and on its base, dilated at its extremities ; 
having entirely the form of the one of Mitiduloides and Picta, 
but running at some distance of the margin; inferior parts 
of the body and legs of a brownish black. 
From the Paroo River, in Dr, Howitt’s collection. 
Silphomorpha Quadrisiquata: length 3’; black, glossy ; the 
sides of the thorax and elytra yellow; the centre of the 
first having generally a red or yellowish longitudinal band ; 
elytra smooth, very feebly striated, and having each two yellow 
spots, the first at the base in its middle, bifurcated at its 
inferior extremity, and the second not far from the end, 
oblong, pointed at top and growing broader toward the ex- 
tremity; parts of the mouth, lower side of the body and 
legs of a light yellow brown; the sides of the thorax and 
abdomen often black. 
This insect is rare in Victoria, and more common in South 
Australia, ~ — 
Stlphomorpha Bicolor: length, 34’; black, glossy ; elytra 
very feebly striated ; margins of the thorax and elytra black ; 
a longitudinal band on the latter nearer to the margin 
than to the sutura, arched, wide at its base, where it forms a 
sort of a hook; it terminates a little before the extremity, 
and does not touch the sutura; parts of the mouth, antennz 
and inferior side of the body brown; the lower sides of the 
thorax and abdomen black. 
From Rockhampton, Mr. Thouzet; and Port Denison, 
Mr. Girardin. 
Variety, similar; but the thorax yellow, with only a 
black longitudinal band on each side.
