xLvil. fig. 7, D.),the third joint being but slightly bilobed. The mentum is 
very short, and transversely linear, and completely concealing the labium 
and mazille, which are densely clothed with hair in front, (Ibid. A.) The 
species are peculiar to America. 
Still, however, the general, as well as essential, characters of the genus 
approach so near to those of Spondylis, (Tab. Supp. xivt. fig. 8, A BC DE 
andF’,) that we cannot regard the latter otherwise than as the connecting link 
between Parandra and Prionus, and that the situation given by Latreille, 
in his last work, to these genera, is the correct one. How are we, how- 
ever, to regard all these resemblances between this genus as well as some 
of the preceding and Lucanus ? are they not too striking and important 
to be considered merely as analogies ? and would it be unnatural to re- 
gard this genus as the osculant one between Lucanus among the Lamel- 
licornes, and Spondylis and Prionus amongst the Longicornes ? we find 
the two great groups similar in their herbivorous habits, and also similar 
in comprizing the giants of the order to which they belong.*

appears to have been first noticed, without any characters, in the Fa- 
milles Naturelles, where it was placed as the last genus in the family 
Cucujide. In the second edition of the Régne Animal, Vol. V. p. 53, 
however, we find the genu$ removed, and doubtingly placed in the La- 
griaires. The characters are there detailed, which appear to be very sin- 
gular. The genus is established, ‘ Sur un insecte trouve en Ecosse, dans
