FURTHER NOTES ON AUSTRALIAN COLEOPTERA, 
Adortphorus, gen.nov. 
Mentum sat angustum, convexuiu, antice lequaliter angustatum, 
ligula vix clistincta ; palpi labiales sub niente inserti, articulo 
ultimo ovali ; maxilla lobo superioi*e minuto cylindrico, apice 
j)enicillato ; mandibulm baud dentatie ; antenme lO-articulatm, 
flabello parvo ; tibiae ut Dasygnathi format*; tarsi posteriorps 
modicae, articulo prime sat elongate apice vix dilatato; feminae 
caput prothoraxque simplicia, hoc post marginem anticum ut 
Dasygnathi feminei (sed obsolete) sculpturato. 
I propose this generic name for a small Dynastid which I have 
no doubt is identical with Dasygnathus Couloni, Burm., a species 
that certainly ought not to be associated with Dasygnathus 
Dfgeani, W. S. !Macleay. Unfortunately my specimen, like Dr. 
BurmeLster’s, is a female. I do not like founding a new genus 
without knowledge of the male, but as this insect has been 
described, and cannot, whatever its male may 1*, find a natural 
place in any hitherto chai'acterised genus, I think I am taking 
the best course practicable in thus naming it. It agrees so well 
with Dr. Burmeister's description specifically that I need not 
add to that description beyond saying that in my example ti e 
colour of the upper surface is pitchy black rather than a genuine 
black, and the “ small protuberance on the vertex of the head ” 
is placed very far back and is very slight.
