Lincolnshive Coleoptera. 281 
This specimen was forwarded for verification to Mr. F. Balfour- 
Browne who writes :—‘‘ The only other records are, Kent W., Suffolk, E., 
Norfolk E. & W., Cambridge & Surrey. I took about a dozen in E. 
Norfolk and three specimens in Cambridge.*’ In the Coleoptera of the 
British Islands (1887). The Rev. W. W. Fowler says :—“ Very doubtful 
as British; its claim to be acimitted into our lists rests on a single 
Specimen taken twenty years ago .. . . : it has however never 
been found since and requires further confirmation.”
