NOTES ON BRITISH GEODEPHACxA. 69 



nocturnal brushing, which has proved very successful, and I 

 have known the locality of a rare species discovered solely 

 by that means; and for these Carabideous insects especially, 

 I would call attention to a plan adopted by Baron Chaudoir, 

 which is, to spread a white cloth on the ground at night in 

 some promising locality with a brilliant light in the centre, 

 and the insects being attracted thereto may be secured in 

 numbers, and many species, which had not previously been 

 suspected to exist in the locality where the plan is adopted, 

 may by that means be discovered. Such has been the result — 

 and certainly the contrivance is a good one — where it can be 

 practised without arousing the jealousy and displeasure of 

 gamekeepers and revenue officers. 



I transcribe M. Chaudoir's account for the benefit and 

 encouragement of those Entomologists who are disposed to 

 adopt his scheme, and I wish them equal success. " La 

 soiree fut tres-chaude, et j'en profitai pour essay er d'un 

 moyen que M. de Steven m'avait indique com me tres- 

 cornmode pour se procurer beaucoup d'insectes que Ton ne 

 rencontre presque jamais autrement. II consiste a poser deux 

 flambeaux sur une nappe etendue a terre a proximite des 

 lieux qui servent en general de refuge aux insectes, tels que 

 prairies, bois, pierres, etc. : les localites humides sont en 

 general preferables. Attires bientot par l'eclat de la lumiere, 

 les insectes de tous les ordres s'y portent en foule. Je pris 

 de cette maniere des Harpalus, des Ophonus, des Chlamius, 



des Brachelytres, des Hydrocanthares, des Hydro- 



philiens, des Pselaphiens et d'autres insectes." — Enumera-

In the following record of the captures of our more un- 

 common species of Car abides, it will be perceived that the 

 most important results have been attained since the publica-
