The two Car abides figured in this number ( Clivina and Leistus) 
present as different aspects as any European forms contained 
in the family, one of them being narrow, nearly cylindric, 
with short strong legs, the anterior notched, the antennae 
short and moniliform, (a structure very rare amongst this 
tribe of beetles) ; the other being broad depressed, with long 
slender legs, the anterior not notched, and the antennae very 
much elongated : upon examining the mouths however, by ac- 
curate dissection, which we hold to be the touchstone of truth, 
ample proof will be found of their being related to each other, 
although the trophi exhibit very great and very remarkable 
modifications. We shall be pardoned for these observations, 
when it is recollected that Linnaeus himself, misled by analogy, 
included Clivina with Tenebrio : and such remarks are not ad- 
dressed to the profound entomologist, but are intended to guide 
the student, wdio might be unable to satisfy himself for what 
reasons two insects so decidedly different in contour, should 
be included in the same family. 
With the group called Leistus y Linnaeus appears to have 
been unacquainted ; and we wish to call the attention of the 
physiologist particularly to the Lip, which does not appear to 
us to have been before accurately delineated. The following 
are our British species. 
1. L. spinibarbis Fab., Marsh. — caeruleus Lat., Sturm . — 
pallipes Panz. 89. 2. 
Found during May, June, August and September, in sandy 
situations, under stones and dry leaves in woods. 
2. L. fulvibarbis Hgg., Dej ., Nob. 
Independent of considerable differences of colour in this and 
the former species, our insect (a male of which is figured) is 
much smaller, and the thorax is more convex, and narrowed 
at the base : it is rarer, but occurs in Kensington Gardens, 
Battersea Fields, and other places round London, at the same 
periods as the first. 
3. L. spinilabris Panz. 39. 11. Fab. — brunneus Marsh . — * 
rufescens Sturm. — rasco-aenea Panz. 89. 3. 
April, sandy places, Norfolk. 
4. L. rufescens Fab., Lat., Marsh. — terminatus Panz. 7. 2. 
Found during the spring in the neighbourhood of London : 
it is rarer than No. 3, from which it is distinguished by its 
black head and tips of the elytra. 
The plant is Neottia spiralis (Ladies’ Traces).
