Habitat—Cooktown, Queensland pee by C. French, 
Esq., F.L.S.). 
The above description is drawn up from a specimen of a female, 
being the second species of this singular genus. It agrees with 
the other in general aspect and the curious translucency of the 
pale portions of the scutum, which permits the internal muscula- 
tion, &c., to be seen even in dry specimens, but differs largely in 
markings and other details, as, for example, the presence of lobi- 
form elytra.

The synonymy is indicated by Saussure, and a variety recorded 
with two testaceous spots on the disc of the pronotum.

Brunner states that DeHaan’s description, based upon one 
individual (Novara Museum), was very short, and that he sup- 
plemented the same (apparently from the same specimen).
