Mr. Hardy on the Entomology of the Cheviot Hills. 161 



gravel, or the porphyritic rock itself, and yields no shelter ; 

 while the streams rapidly overflow and sweep off the debris, 

 in which insects might harbour. The sides of the ravines are 

 roughened with crowded patches of angular stones, loose and 

 shifting, — in summer, arid as a desert ; which also enclose 

 the bases of the precipitous rocks, where a little cool shelter 

 might be obtained, being merely at places hidden from the 

 view by a poor scanty soil. The trees on the outskirts are 

 too few and open to modify the general bleakness. As a 

 whole it does not differ much from moorland of much less 

 elevation. 



My first attempt to look up the north and north-east back 

 of Cheviot was rather discouraging. I was led to make it in 

 July, 1869, being flattered by the capture, in the spring, of 

 two of Carabus glabraius, which were rambling about the 

 banks, below the rocks at the Bizzle. I made trials of both 

 the Bizzle and Dunsdale, and it was more easy not to find, 

 than to capture anything worth carrying off. I present the 

 list as a starting point.
