and apex; disc behind peduncle slightly depressed; base wide, 
humeral angles rounded but a little marked; apex sinuate on 
each side at extremity of 9% interstice ; striae strongly impressed, 
linear, entire, deeper on apical declivity; interstices hardly convex, 
narrow and convex on apical declivity, 2° wider and bearing a

Differs conspicuously from all the Australian species which 
have been referred to Stenolophus and Acupalpus by its stouter and 
more robust form; and I believe these characters will distinguish 
it also from Amphibia pallipes !) Montız., from New Caledonia, 
which is unknown to me in nature. 
The following features are found in this species, and. serve 
to show its position in the tribe Harpalini; (1) labial palpi with 
penultimate joint bisetigerous; (2) eyes close to buccal fissure 
!) It is the opinion of the Rev. Thos Blackburn that the Australian 
species now referred to Stenolophus require to be separated from that 
genus (cf. Trans. Roy. Soc. S. Aust. 1901, p. 115). If this view be ac- 
cepted, probably the name Amphibia (Montrouzier, 1864) will be appli- 
cable to these species.
