The few species that compose the genus Tar us vary consi- 
derably in their structure, some having ample wings, whilst 
others have the smallest rudiments only; the securiform labial 
palpi are also said to be a sexual character, and in T. basalis 
they are cylindrical in both, thereby making a near approach 
to Polistichus. 
I must here be allowed to observe, that had not the name 
of Tarus been given by Clairville long since to this genus, I 
should not have dropped the well known one of Cymindis, 
although it signifies a species of Hawk ; because were such a 
rule to be adopted, we should be compelled to abandon the 
names of many of the established genera of Linnaeus. 
The following have been recorded as natives of Britain. 
1. humeralis Fab., Oliv. — Lat . and Dej. Icon. £.11. f. 2.— 
Sturm.pl. 164. — Taken near Swansea, Glamorganshire, 
and at Cuckfield in Sussex, by Dr. Leach and the Rev. 
F. W. Hope. 
2. Homagricus Duft. — Lat . a7idDej. Icon. t. 11 .f. 4.- — Sturm. 
pi. 165. B. — I took a single specimen under a stone in a 
gravel-pit on Witchingham Heath, Norfolk, in 1810. 
3. angularis Gyll. — Lat . and Dej. Icon.pl . W.f 1 .— - -lunaris? 
Duft . — Sturm.pl. 166. A. — Taken at Swansea. 
4. macularis Mann. — Dej. Coleop. v. 1. p. 212. n . 13. — The 
locality of this species has not transpired: Scotland is 
the most likely habitat, as it is found in Sweden and 
Finland. 
5. basalis Gyll. — Curt. Brit. E7it. pi. 235. — For specimens of 
this fine addition to our Carabidse, I am indebted to 
Mr. Edward Hobson : they were taken in April near 
Halifax, Yorkshire, I believe on Midgley Moor; and 
about the same time others were captured by L. Rudd, 
Esq. on the shores of the river Tees. 
Betonica officinalis (Wood Betony) is represented in the 
plate : the plant erroneously called by this name at folio 202, 
it must be remembered, is Prunella vulgaris.
