to this species, which is described in the Stockholm Kongl. Vet. 
Akad. Handl., 1833, p. 327, tab..ix. fig. 19, fig. 3¢. The de- 
scription is in Swedish, with a Latin diagnosis of five words. 
It isa black shining insect with a short bifid lower lip, but differs 
from M. Fries’ figures, which are exceedingly well executed, in 
the obtuse not-pointed spine behind the eye, and the well-marked 
apiculus terminating the sutural line; there are also two rather 
“prominent raised lines on each elytron, which are not shown on 
the plate. ‘The members of the genus Psalidognathus, judging 
from the common P. Friendii, are very variable in size, colour, 
and even in form, according to the sex ; and when this is the case 
it is difficult to arrive at a satisfactory conclusion as to specific 
distinctness without a large number of specimens. The males 
differ from the females, inter alia, in the fore-tibize being thickened 
and to a certain extent fusiform, with the inner margin clothed 
with short closely-set hairs.
