 Norfolk, Kensington, Cambridge, Dollar, Swinton ; near Glasgow; 

 Paisley ; Oban, common. 



6. C. adspersus, Fab., GylL, Steph., Aube. The rarest of the 

 genus : I have never been so fortunate as to meet with it, though some 

 years ago it was frequently taken by collectors. It is shorter and 

 relatively broader than any of the allied species. 



7. C. Grapii, GylL, Steph., Erich., Aube. C. niger, Lacord.

 Mr. Newman has taken it abundantly at Birch Wood, in Kent.

 Common. 



2. I. obscurus, Marsh, Steph. I. quadriguttattus, Lacord, Erich. 

 Common. 



(I. Prescotti, Mannerh., Aube. Appears to be simply a variety of 

 I. fenestratus, taken at Petersburg. Colour castaneous instead of 

 piceous.) 



3. I. fenestratus, Fab., GylL, Steph., Aube. I. subaeneus, Steph. 

 I. lacustris, Fab. Local: occasionally in the fens; Welton Place, 

 near Daventry ; Croydon Canal, Parley Copse, Leominster. 



4. I. guttiger, GylL, Steph., Erich., Aube. More common in 

 northern counties than near London ; Bewdley Forest, Gosforth, 

 Paisley. 



5. I. angustior, GylL, Steph., Erich., Aube. London district, 

 Whittlesea Mere, Whitsunbank Hill. This local species has more 

 recently been discovered by Dr. Power at Woking, and taken in 

 some abundance by the London entomologists. It is most closely 

 allied to the preceding species, I. guttiger ; and though it is possibly 

 distinct, I am not able to discover any clear, satisfactory specific 

 characteristics. 



(I. meridionalis, Dej. Allied to I. uliginosus ; the same form, but 

 broader ; colour darker, of a different metallic tint ; elytra without 

 the distinct marginal band of the following species.)
