anxious to make this part of the system perfect in his valuable 

 work " Considerations Generales," &c. Clairville's " Ento- 

 mologie Helvetique" was a most valuable acquisition to the 

 student; and the Monograph by Professor Bonelli, as well as 

 the acute observations of Dr. Leach, have left but little to 

 be done so far as relates to the European genera. In 1792, 

 when Fabricius published his " Entomologia Systematica," the 

 Genus Carabus contained only 195 species, collected from 

 every quarter of the globe ; and now in Britain alone there 

 are 275 species of Carabidse knovvTi. 



The Genus Nebria as it now stands contains only two British 

 species; the one figured, which is drawn rather larger than life, 

 was first discovered in Yorkshire by Mr. Spence, (well known 

 as the coadjutor of Mr. Kirby,) and a single specimen was 

 afterwards taken by Mr. Wilkin the 28th Sept. 1814 beneath 

 a fragment of rock at Hilston near Hull in the same county. 

 The other {N. complaiiata) — not so rare as N. livida, but ex- 

 tremely local — Sir Joseph Banks first discovered at Swansea. 

 Dr. Leach many years after found it in the same situation; and 

 in Sept. 1822 I was fortunate enough to take it in great abun- 

 dance under the stones at high-water mark, on the sandy shore 

 of the River Taw, near Braunton Burrows North Devon, 

 after having been searching in vain for the larva of Sjj/mix 

 Euphorbicc. 



Medicago lupulina (Nonesuch, black or Hop Trefoil), both 

 in flower and fruit, is the plant figured in the plate.
