8| mm.). Another from Thursday Island, in the Macleay 

 Museum, has the prothorax entirely pallid. The species is 

 a typical Trichalus.

A specimen from Forest Reefs differs from the type of 

 Raymondi in having the head entirely dark. The antennae 

 may possibly reach quite to the middle of the elytra, 

 although they do not appear to me to extend quite so far, 

 but there is no doubt as to raymondi being a synonym of 

 semicostatus with the description of which I did not check 

 it, owing to that species being referred to Metriorrliynckus. 



The species is very close to discoideus, which, however, 

 always has the disc of the elytra more or less infuscate ; 

 the shape of the central prothoracic areolet appears to be 

 somewhat different.

A specimen of this species is in the National Museum 

 from Loutit Bay. I have seen two other specimens from 

 Victoria (one in the National, the other in the Macleay 

 Museum) which in size, colour and general appearance 

 exactly resemble this species, but which belong to one 

 of the numerous varieties of Metriorrhynchus rujipennis.
