NEW BRITISH SPECIES, ETC., IN 1870. 43 



evidently the true C.fumatus of Gyll. As Erichson notes, 

 it curiously simulates one of the larger species of Corticaria ; 

 and in the form of its elytra, size, and colour of its pubescence 

 is most allied to C. validus, from which it differs in having 

 its thorax more nearly quadrate, with the anterior callosity 

 more developed (sub-cyathiform, and somewhat suggestive 

 in that respect of C. acutangulus). Its different thoracic 

 callosity, shape of elytra and short golden pubescence, not 

 disposed in striae, will serve to distinguish it at once from 

 C. cellaris. 



De Marseul follows Erichson in considering Stephens' 

 fumatus as rightly named, and therefore British j but 

 Stephens' insect is dentatus,

 Mr. Bold publishes a redescription by Mr. Crotch of 

 Hardy's insect, which appears to be one of the Ebnidce, and 

 closely allied to Macronychus, though its antennae are eleven- 

 jointed. 



No further evidence is adduced in support of the claim of 

 this insect to be considered British.
