210 Prof. J. C. Schiddte on the Classification 
the ventral surface more vaulted, the marginal ribs of the elytra 
effaced, their deflected lateral part (epipleura) is more bent 
in and diminished in size behind the cox; the legs are more 
arranged for running, with delicate feet and weak claws; the 
hairy covering becomes more close and silky, the sculpture less 
distinct, the ribs of the elytra lower, the colour duller, yellowish, 
brown, red, but never strongly metallic. 
The development of the H/ater-type in the opposite direction, 
towards springing and day life, is characterized by the following 
marks :— 
1. The eyes become less smooth, the facets protrude more, 
and the appearance of the cornea becomes duller. 
2. The sensitive pores are more equally spread over the whole 
surface of the antenne. 
3. The forehead slopes more gradually down towards the 
mouth ; the antenne are further removed from one another ; the 
prothorax is more elongated, the mucro saltatorius presents a 
more direct continuation of the prosternal spine; the legs pro- 
trude more to the sides; the animal is less arched both above 
and below, the margins are sharpened, the whole outline becomes 
a more elongated ellipse; the marginal rib of the elytra becomes 
flatter and remains entire; the epipleura is more straight and 
broader; the legs are more especially adapted for walking and 
chmbing, with club-shaped terminal tarsal jot and powerful 
claws ; the body is more closely haired, the sculpture coarser; 
the ribs of the elytra are raised at the base; the colour is 
heightened often to metallic lustre, or to distinct design. 
If every combination of characters drawn from this circle were 
used for the foundation of genera, we should reach that point 
towards which modern classification for a long time has been 
tending in this family as in others, viz. the identification in 
most cases of genus and species; for all these features unite in 
the most multifarious manner, constantly appearing in new 
cross combinations. In the following synoptical table of the 
Danish species these characters are therefore considered sub- 
ordinate, and only used for the classification of species within 
the boundaries of the different genera. These latter are founded 
on other characters, which have been explained in all essential 
points in the preceding chapters, so that but little remains to 
be added here. 
That Sternoxi exhibit similar differences in the composition of 
the sockets of the middle pair of coxe to those observed in 
Carabidze has been noticed in an earlier treatise*. Since then,
