58 PLATE CLIX. 



fcareely exceeds one half of the length of O. AfsUus in England, yet if 

 we may form an opinion of the German fpecimens from thofe 

 figured by Sulz, they are larger than with us. 



The Onifcus Agilis of Perfoon, figured in Panzer's Work*, cor- 

 refponds perfectly with ours in fize ; and the minute markings on 

 the fhells, if carefully examined with a glafs, will be found nearly 

 alike. The antennas of the figure in Sulz feems rather contrary to 

 the fpecific character of the infect ; and that of Panzer's, though of 

 another fpecies, more refemble thofe of our fpecimen. 



Of the Onifcus AJellus we find different coloured fpecimens, fomc 

 are almoft white with grey marks, others are nearly deep black ; 

 we find alfo, Onifcus Aquaticus liable to variations, though not fo 

 much as the former infe£t in fome the light ground colour is very 

 di[tin<St, in others rather confufed. Some are deeper coloured ; and 

 again, many, when firft taken, have a fine glowing, olive brown ap- 

 pearance throughout, though lefs vivid than that of Onifcus Agilis 

 before noticed.
