Probably Hydrophilus signaticollis of Megerle, an undescribed species. 



I detected this species long since, and gave its locality to Mr. 

 Ingpen, who published it by my MS. name in his useful " In- 

 structions ;"" and have captured a single specimen near London, I 

 believe at Hertford, and obtained others from Whittlesea-mere.
