with it, and considers it allied to Astrapaeus, which has the 
habit of Quedius, and is nearly related to Goerius. Fabricius 
places it between Stenus and Pasderus, Gyllenhal between 
Lomechusa and Bledius, and Dr. Leach between Dianous 
and Oxytelus. As many of these genera have been illustrated 
in this work, I shall leave entomologists to draw their own 
conclusions on the subject. 
There are only 2 species inhabiting Europe. 
1. O. rufus Linn. Faun. Suec. 231. 84*4?. — Panz. 16. 19. — Sam. 
pi. k.f. 1 1. 
Smooth shining rufous, head and mandibles black : elytra 
black with a large ochreous spot on each shoulder, a line of 
punctures on each side the suture, and 2 others abbreviated 
on the disc of each elytron, with a few scattered punctures 
between them : abdomen with the two last joints black, as well 
as a broad mark on the antepenultimate segment : breast, coxae, 
trochanters and base of thighs black. 
Mr. Brightwell of Norwich once took me to a corn-field at 
Thorpe near that city, where a great number of fungi were 
growing, and we scarcely found one that did not contain seve- 
ral specimens of this pretty insect. I have also beaten it out 
of Brambles and White- thorns : it is therefore probable that it 
is likewise carnivorous. 
2. O. maxillosus Fab. — Curt. Brit. Ent.pl. 418. 
Smooth shining and ochraceous : maxillae variegated with 
castaneous : head and thorax black, pitchy castaneous beneath, 
the former sometimes with 2 castaneous spots before, the 
latter with one above the scutellum : elytra lurid ochre, the 
posterior angles black, with a line of punctures on each side 
the suture, and two deep abbreviated ones on the disc of each 
elytron, with a few punctures scattered between them : abdo- 
men reddish ochre, with a line of obscure brown spots down 
the middle. 
Said to have been taken I believe in Suffolk and Devon- 
shire, but very rarely. It is remarkable that this insect should 
have been found in England, since it is not an inhabitant of 
Sweden, and has never been discovered I understand in 
France. 
The Plant is Cardamine hirsuta (Hairy Ladies’ Smock).
