92 Proceedings of the 



M. Kraatz, a decision which a careful examination of the speci- 

 mens of intermedins so kindly furnished to me by that gentleman 

 has given me no reason to alter. If any of the varieties are to 

 be exalted into separate species, castaneus, St., is obviously the 

 one best entitled to this. 



Referring back then to my general comprehensive description 

 of this species above given (p. 13), I have only to add, that the 

 extreme examples of the foregoing varieties may be known with- 

 out much difficulty by the following characters. The less decided 

 examples form intermediate steps, and it will often be found 

 scarcely possible to say to which of the nearest varieties they 

 belong. 



1. Pale ferruginous varieties. 

 Var. A. Thorax widest at front, as shown in fig. 3 ; margins 

 paler than centre. 



Var. B. C. angustatus, Kraatz. Thorax widest not at the very 

 front, but a little before the middle, as in fig. 2 ; margins 

 paler than centre ; depressions on thorax not deep. Elytra 

 nearly parallel, darker at suture towards apex. 



Var. C. C. intermedins, Kraatz. Thorax a little broader than in 

 var. B ; margins paler than centre, with deeper depressions 

 on thorax. Elytra slightly widened in middle, entirely red 

 ferruginous. 



2. Dark chestnut variety. 



Var. D. C. castaneus, Sturm. Thorax widest in middle, as shown 

 in fig. 1, of a more solid consistence than the pale varieties ; 

 margins not paler than centre. 



This species is found over the whole of Europe, and Gebler 

 mentions it as having been taken in the south-west of Siberia. 

 The whole of the above varieties are found in England and Scot- 

 land, but var. D is the commonest and var. A the rarest — (of it 

 I have only seen one example). 



2. C. spadiceus, Sturm.
