by Reiche in the work above referred to,) whilst De Laporte formed 
it (with the same erroneous specific name) into his slightly charac- 
terized genus Mentophilus (Hist. Nat. An. art. Col. vol. ii. p. 74, 
pl. 4, fig. 4). Reiche has, however, proposed for it the specific 
name of 4. carinatum. (PI. VIII. fig. 4, and details.) 
The real Ateuchus Hollandie, the original specimen of which, 
described by Fabricius from the Banksian Cabinet, I detected 
amongst the unarranged insects of that collection in the possession 
of the Linnzean Society, although still authenticated by the original 
label, bas been formed by Mr. Hope into the genus Tessarodon, 
in his “ Coleopterist’s Manual,” vol. i. p. 55; the insect itself 
being figured in his plate 3, fig. 15. More recently Mr. Hope has 
obtained two other species of the same genus from Australia, 
which have enabled me to give the following generic details; but 
as these insects absolutely disagree with the character expressed 
by the name Tessarodon, (having only two teeth in the front of 
the clypeus,) another name ought to be given to the genus.
