NOTES OX BRITISH GEODEPHAGA. 67 



rarities as Carabus intricatus and Diachromus Germanus. 

 We should be unwilling to admit it without a more careful 

 and systematic investigation, though we well know that in 

 many other parts of England (especially in the fen districts), 

 the advance of extensive drainages and cultivation has most 

 assuredly had the effect of entirely banishing those Ento- 

 mological productions which formerly abounded in such 

 localities. The fact is, except certain portions of that county 

 and those at particular seasons of the year, not the most fa- 

 vourable for Geodcphaga, it has been very little searched of 

 late years for that class of insects. An important portion, 

 namely, all that wild district bordering on Dartmoor, not at 

 all. During a very brief visit, limited in fact to two or three 

 days, which Mr. Wollaston paid to a wild uncultivated tract 

 called Slapton Ley, not far from Start Bay, he succeeded in 

 obtaining several examples of a fine Harpalus, new to the 

 British Fauna. I should rejoice, therefore, if any hardwork- 

 ing, practical Entomologist would investigate all those dis- 

 tricts carefully and systematically, and that not merely atone 

 but at various seasons of the year, and especially in the 

 spring, which would there be found most productive. It is 

 unsatisfactory to be obliged to admit that there are yet species, 

 which we are bound to include among- our indigenous Ca- 

 rabidce, on the authority of specimens existing in collections, 

 of which no man living can say, " I have taken such an in- 

 sect." Lcbia hcemorrhoidalis, Brachinus sclopeta,* Chhenius 

 agrorum, Anchomenus modestus and Diacliromus Germa- 

 nus, are all (according to Stephens) reputed natives of De- 

 vonshire, but they seem to have entirely disappeared ; their 

 places in our cabinets are vacant, till we almost begin to 

 doubt whether they have not-bcome utterly extinct, even if 

 we do not go to the extent of discrediting the fact of their 



* Through inadvertency, I stated that the Rev. A. Matthews received 

 this insect from Mr. Vigors. I should have said from Mr. Sowerhv.
