Notes on Australian Coleoptera. 113 
From the Murray River. 
Note.—This insect is also allied to Suturalis, but its form 
is more oval, more narrow; the yellow spot of the elytra is 
much broader at the base, so as to have, when the two elytra 
are united, a very long triangular form. 
Silphomorpha Thouzeti: length 24’; very nearly allied to 
Marginuta, but of a more elongate and oval form; no yellow 
margin to the thorax, nor to the elytra; the sutural spot 
rather broader than in E'marginata ; parts of the mouth and 
antennze of a pitchy brown; lower parts of the body and 
legs of a dark yellow. 
Rockhampton, Mr. Thouzet. 
Silphomorpha Rockhamptonensis: length 44°; of a dark 
pitchy brown, almost black, glossy ; parts of the mouth and 
antenne of the same colour; elytra smooth, with a dark 
yellow spot arising near the base towards the middle of the 
breadth, and directing itself obliquely towards the sutura, 
which it joins a little below the middle, forming thus, by the 
union of the two elytra, a sort of broad V; inferior parts of 
the body of a dark brown; legs rather lighter. 
Rockhampton, Mr. Thouzet. 
Stlphomorpha Occidentalis: length 5’; general form 
rather broad, compressed ; of a pitchy brown; parts of the 
mouth and margin of the thorax and elytra of a light reddish 
brown ; a slight impression on each side of the thorax on its 
posterior margin; elytra with light strize formed of points ; 
the greater part of their surface is covered by a very large 
yellow spot which begins behind the humeral angle and joins 
obliquely the sutura, extending to near the extremity of the 
elytra; inferior parts of the body and legs of a light reddish 
brown. 
Swan River. Sent to me by the Rev. Mr. Bostock. 
Silphomorpha Brishunensis: length 5’; of a pitchy 
brown; parts of the mouth, antennez, and a* very narrow 
margin on the sides of the thorax and elytra of a brownish 
red; elytra with a few longitudinal undulations, but no 
strie; they present on the sutura a long, narrow, and 
yellow spot extending to very near the scutellum and the 
extremity; it is moderately expanded towards its centre; 
inferior parts of the body of a dark brown; legs rather 
reddish. 
Received from Mr. Wilson, of Brisbane; also from Port 
Denison and from the Clarence River, Mr. Wilcox. 
Silphomorpha CGuttifer: length 34; very nearly allied
