Although the Baron Dejean has united two groups to form 
the genus Clivina , we shall not hesitate to adopt the division 
of them pointed out by Panzer and followed by Leach, and 
also Latreille in his Families Naturelles , by which means the 
majority will be comprised in the genus Dyschirius, from which 
Clivina is distinguished by a more quadrate and less globose 
thorax, and by more completely digitate tibiae, as well as oral 
characters, which we shall point out when we arrive at their 
illustration. 
Our insects no doubt burrow in moist sandy situations, for 
which purpose they are furnished with a small head, a very 
strong thorax, (capable of very extensive motion, from its 
being attached to a peduncle,) and digitate anterior tibiae. 
The only two species known to inhabit Europe are natives 
of this country, and were first separated by Herbst. They have 
however been since confounded by Gyllenhaland Dejean; but 
our friend Mr. Bennett has pointed out a character which, 
independent of colour or size, will at once define the species, 
one having long wings formed for flying, the other such short 
wings that they cannot possibly enable the insect to fly. This 
latter 
1. C. fossor Linn . — arenarius Fab., Panz ., 43. 11. — distans 
Marsh. 
is a common insect in sandy situations, under stones and upon 
marshes after floods amongst rejectamenta, throughout the 
country, during the months of March, April and May. 
2. C. Collaris Herbst ., Nob. 
is a more local species, confined apparently to the neigh- 
bourhood of London, being abundant in the gardens at Lam- 
beth and on the shore of the Thames at Battersea, from 
April to the end of June. It is a smaller insect than C. fossor ; 
and as we find some with, and others without the large brown 
spot towards the apex of the elytra, we are disposed to con- 
sider it a sexual distinction, the former being we suspect the 
C. discipennis of Megerle. We have also found in Norfolk two 
pale varieties of C. fossor , which appeared to be immature, and 
these may probably be the C. discicollis of the same author. 
The plant is Galcopsis Ladanum (Red Hemp-Nettle).
