The Carabus Discus of Fabricius appears to be the type of 
Ziegler’s genus Blemus ; but as I had not a specimen for dis- 
section, I have drawn the characters from B. paludosus , 
which I have no doubt belongs to the same group, and not to 
Trechus, as was stated at folio 203. The Blemi are very 
nearly related to Aepus; yet there are good distinctive cha- 
racters : the most remarkable one perhaps in Blemus is, the 
ciliated margin of the mandibles. 
The following are British species. 
1. B. Micros Herb . — Panz. 40. 4. — III., Verz.p. 180. — Curtis’s 
B. E. pi. 310. — rubens Steph ., and discus Steph ., but 
not of Fab. 
There can be little doubt that this is the true C. Micros , 
although Panzer’s figure is rather too pale ; and it certainly is 
neither Fabricius’s C. Discus , nor his C. rubens. 
This insect is found in damp gardens near London, in 
April and May, and in meadows and marshes. Mr. Heysham 
takes it near Carlisle in August under rejectamenta. 
2. B. longicornis Sturm. Deut. Faun . 6. 151. A. 
I took a single specimen the 30th of June, under rejecta- 
menta, on the sands near Broughton, Lancashire. 
3. B. Discus Fab. Ent. Syst. 1. 164. 178. — unifasciatus Panz. 
38. 7.— Marsh. 466. 
If the Fabrician description were very accurate, his C. Discus 
could not belong to this genus ; for he says the thorax is 
rounded. In Fabricius’s last work, however, he refers to the 
above figure of Panzer ; and Illiger does not express the least 
doubt concerning it. 
Mr. Hobson takes this pretty insect on the banks of the 
Irwell in July; it is found also in July in the neighbourhood 
of London, and in Norfolk and Suffolk. 
4. B. paludosus Gyl. 2. 34. 20. — rubens Steph. Cat. 
Fabricius’s C. rubens appears to agree much better with the 
insect that has been called Ocys tempestivus. 
This insect is universally distributed, having been found in 
Zetland, on the Grampian Hills, near Carlisle, Hull, and Nor- 
wich, on the sand hills at Swansea, and in Hampshire. 
5. B. pallidus Sturm, tab. 153. A. 
This insect I first discovered in August under clods of earth 
at the base of the cliff at the back of the Isle of Wight ; I 
found one dead last May in the Isle of Portland, and took 
another under the cliff* at Dover in July. 
The B. Fphippiger or B. consputus of Duftschmid has been 
placed in this genus ; it is however more nearly related to the 
Trimorphi of Stephens, and may be at once distinguished 
from the Blemi by the absence of the elevated oval spaces 
round the eyes. 
The plant is Beta maritima (Sea Beet).
