The Oil-Beetlk and rm, Sitakis-Bei:tli 



In the upper half of the picture is seen the counnon oil-beetle, and some of its earlier stages. On the hawkweed flower several grubs 

 are waiting for a minuig bee, to whose hairs they can attach themselves, and so get carried to the nest. In one cell of the nest a grub 

 is feeding on the bee's egg, which floats on honey. In another cell it is seen as a chrvsalis, after passing through several intervening 

 stages. The lower division illustrates similar stages in the life-historv of the sitaris. ' .About twice the natural size.
