sending to William Spenee from Halvergate Carabus clathratus, an insect 

 only found nowadays in Scotland and Ireland." 



C. and J. Paget in their "Sketch of the Natural History of Great 

 Yarmouth and its Neighbourhood," 1834, also record the species from 

 Belton Bog, which is in Suffolk, in June ; and we find a second record 

 from Bungay in the same county in the last volume of Morris' 

 Naturalist, 1858, p. 16 : " Carabus clathratus. — Once by my father, a 

 few years ago, close to the town, and is now in our collection. 

 W. Garuess." [This is Dr. W. Garneys of Repton, the friend of 

 Canon Fowler and Dr. Mason, who died in 1881, and whose collection, 

 upon the death of his widow (since 1905) passed into the former's 

 Lands. Canon Fowler has been so good as to tell me that there was 

 at that time specimens of neither C. clathratus nor peculiar forms of 

 C. gramdatux, which might have been mistaken for it, in the collec- 

 tion]. Edwards quotes this in brackets (Trans. Norf. Soc, 1899, 

 p. 521) ; and both the county records are referred to by me in " The 

 Coleoptera of Suffolk" (J H. Keys, Plymouth), 1899, p. 1. They 

 appear to have been overlooked or considered too doubtful for re- 

 production in Fowler's "Col. Brit. Isles," 1, 1887, where the Halvergate 

 record is accredited to Stephens ; but in the Supplement of 1913 both 

 are entered. Excluding Scales' obscure captures, we have approximately 

 the dates : Haworth at Halvergate, in 1809 ; the Pagets at Burgh and 

 Belton, in 1833 ; and Grarneys at Bungay, in 1855. 



The only entirely satisfactory method of proving these (at least) 

 four specimens to have been erroneously determined is by examination 

 of the individuals in question ; and this is, in the circumstances, 

 obviously impossible nowadays — even the latest example has dis- 

 appeared. But we may, in a negative method, show at least the 

 extreme improbability (in my own mind it amounts to impossibility) 

 of the occurrence of Carabus clathratus in East Anglia. It is not im- 

 possible, though improbable, that Thomas Marsham did not know the 

 species ; both the Pagets were little more than boys, and Gfarneys in 

 1855 only twenty-three years of age. Marsham obviously relied 

 largely for his determination upon > Panzer's figure, which certainly 

 refers to the species under discussion [Panz., Faun. Insect. German., 

 lift, 75 (1801), No. 1]. 



That one of our other species, or a peculiar form of one, was mis- 

 named is far from being impossible : Mr. Newbery writes to me that 

 in 1913, at Potter Heigham, in the Norfolk Broads, he took " a re- 

 markable Carabus in a haycock. I make it a large, bright, brassy
