Mr. Pascoe’s description of this curious genus was read at the meeting of the Entomological Society, on the 
4th June, 1866, and was published in the following month. Mr. King’s memoir was read before the Entomological 
Society of New South Wales on the 5th March, 1866, but the sheet of the Transactions on which it is printed 
contains the commencement of Mr. McLeay’s paper on Amycterida, which was read on the 6th August, 1866, 
and Part V of the Transactions, in which both papers appeared, contains the Journal of Proceedings for the 3rd 
September, 1866. 
The genus has been considered to be allied to the Pausside, as well as the Genus Gnostus. But it possesses 
no direct affinity with either of these groups; and is proved, by the analysis of the Genera Polyplocotes and 
Diplocotes, described above, to be most nearly related to the Ptinide, especially to such groups as Mezium and 
Gibbium. 
The mandibles are elongate-conic, with a narrow notch near the base of the outer margin, on the inner edge 
they are furnished with.an oval, pointed, setose appendage; the maxille (fig. 1a) are minute, strongly setose 
at the tip, the maxillary palpi, arising from a thickened scape, are 4-jointed, the terminal joint long, kidney- 
shaped, and pointed at the tip; the mentum and labium are very minute, long, and slender, terminated by a 
pair of 2- or 3-jointed palpi (fig. 1c) ; the hind legs are much wider apart at the base than the middle ones (fig. 1 4).
