Dejean, and after him Lacordaire, has stated that the mentuff

An error of this kind throws an unpleasant uncertainty on all char

Geodephaga, as given in the chief works on this great group, A char 
ter, which has been overlooked by all authors, is the structure of 1 
anterior tarsi in the males ; these are slightly dilated and furnisL 
beneath with double rows of scales, precisely as in the great grou 
Ancliomenincd and Feroniance. This character is interesting, as it ai 
us, in conjunction with others, in judging of the true afiinities of t 
group. In fact, I think there can be no doubt that the Pericall. 
(together with the greater part of the Lebiance) are closely allied to t 
Anchomenines ; the discovery of genera exactly intermediate I 
tween the two groups, one of which is described in this papt 
completing the evidence. The form of the ligula and its pan 
glossse, given as one of the principal characters of the Pericalin* 
varies a good deal in allied species ; but all agree in possessing broa. 
thin, and elongated paraglossse and a narrow ligula ; the paragloss 
attached to the apex of the ligula and surpassing it in length. TT 
variations consist in the extent to which they surpass the ligula; i' 
one species, C. polygona, they are, as in the genus Eurycoleiis, but ver 
little longer ; in others, they are much longer, and tend more or less \' 
curve inwards, and embrace the tip of the ligula. I do not think th{i 
these modifications are at all of generic value, as hastily assumed bl 
some authors. Before they are claimed as generic characters, tbl 
mouth of every species in a genus should be examined; and this bein 
practically almost impossible, such characters should be used witi 
great caution. I 
The following genera form part of the group Pericalince ; in alii 
as far as I know, the males have squamous soles to the anterior tarsi 
and in Catascopus the first joint of the middle tarsi is also sometime* 
squamous. The male of the fine Catascopus cupripennis has the breas-
