The rank of the Cetoniada, as the most typical of 

 all the lamellicorn families, here receives additional 

 confirmation ; since these beautiful insects,, in which 

 white spots and lines upon a green ground are so very 

 prevalent, fall in, as it were, exactly opposite the 

 splendid Cicindelida, whose colours and markings are 

 so remarkably similar. Two of the most common in- 

 sects in this country, the Cetonia aurata, and the 

 Cicindela campestris, will bring this analogy home to 

 the conviction of the most ordinary observer. It is no 

 less remarkable, that nearly all the insects of these 

 groups fly only during the day, and delight to bask in 

 the sun. The greater part, however, both of the 

 Carabidce and the Scarabceidce, are nocturnal insects, 

 and still more resemble each other by their black and 

 sombre colours. Such, at least, are the majority ; for 

 some few in each partake of the metallic green reflec- 

 tions of the chief types ; but these are among those 

 exceptions, and not the general character. The most 

 satisfactory analogy, perhaps, in the table, is that which 

 shows that the predaceous Dytiscidte, although intimately 

 connected to the Hydrophilidce, are also their repre- 

 sentatives. The connection of Hydrophilus, which, in
