be considered as a subgenus founded on secondary characters, 
viz. the absence of its wings, its more orbicular thorax and 
ovate elytra. 
1. S. madid us Linn ., Fab., Oliv. 3. t. b.f. 61. Marsh . 
is one of the commonest of our beetles, abounding 
even in our houses at all seasons, and is remarkable 
only for a decided variation in the colour of the legs, 
some being entirely rufous, others as uniformly black; 
this, which is a good type of the genus, is the only 
one recorded as British. 
2. S. concinnus Sturm., Nob . 
We have little doubt that the example before us is 
a female of Sturm’s insect ; it is the only specimen 
existing in any cabinet that has come under our ob- 
servation in this country, and was taken by the author 
in Scotland either in July or August 1825. 
It may at first sight be distinguished from the type, being 
smaller, the limbs are much more slender, the head is not so 
large in proportion, the foveae and channel upon the thorax 
are less distinct, whilst the striae upon the elytra (which are 
broader towards their termination) are much deeper; but it 
may easily be confounded with Carabus ( Omaseus) Nigrita Fab. 
The plant is Saxifraga cernua (Drooping bulbous Saxi- 
frage), gathered by Mr. Dale at the summit of Ben Lawers 
in the middle of July.
