Violagonum is a new, monotypic genus proposed for 
Colpodes violaceus Chd. of New Guinea etc. and North 
Queensland. 
Homothes is a primarily Australian genus, with half a 
dozen or more species in Australia and Tasmania. The 
genus is now known to have an endemic species also in 
Java and Luzon (Louwerens, in Treubia, Vol. 21, 1952, 
pp. 215-217). 
[ Aeolodermus emarginatus (Chd.), related to Homothes 
and described as from Victoria, is probably not Australian. 
It occurs from the Malay Peninsula to Celebes and the 
Philippines.] 
Odontagonum is a new, monotypic genus based on a 
new species from North Queensland. 
This list of genera shows that the native Agonini of 
Australia, heretofore thought to include geographically 
isolated representatives of several north-temperate genera, 
actually consist of the following: 
Two chiefly Oriental genera which extend to north- 
eastern Australia: Dicranoncus is represented in Aus- 
tralia by a widely distributed Indo-Australian species; 
Lorostemma, by a slightly defined endemic species. 
One mainly New Guinean genus and species, Vio- 
lagonum violaceum, which extends to North Queensland 
without differentiation. 
Two tentative genera of convenience, Notagonum and 
Colpodes , with about 9, mostly relatively unspecialized 
Australian species. One of these species, Notagonum 
dentellum, is mainly New Guinean; 1, Notagonum lafer- 
tei, shared with New Caledonia; and 1, Notagonum sub- 
metallicum, shared with New Zealand. 
One genus, Homothes, which is chiefly Australian 
but represented in Java etc. by an endemic species. 
And one probably autochthonous (but not necessarily 
very old), flightless genus and species, Odontagonum 
nigrum, confined to North Queensland. 
The general nature of this fauna is consistent with the 
Agonini being relatively recent in Australia, and having 
accumulated there by successive arrivals from (or ex- 
changes with) the Orient and New Guinea.
