young grubs pierce a hole through the back of the mother, and 

 walk off one by one, leaving their exuviae behind, which is that 

 white, membranous substance found in the empty cells of the stick- 

 lac. The lac is of a deep red colour, and is the colouring material 

 employed in the best sealing-wax, as well as in a variety of other 

 articles of common use.

 Cocci nella septem-punctata. Linn. 



Of the coccinella genus there are not less than a hundred and 

 sixty- four known and described species, feeding chiefly on plant- 

 lice, particularly the vine fretter or aptis, and hence highly ser- 

 viceable in clearing vegetables of the myriads with which they are 

 often infested. It is the seven. dotted coccinella that passes under 

 the familiar name of lady-bird, or lady-cow. The shells are red, 

 the seven dots black. It inhabits Europe generally, and is said, 

 like several other insects of the order coleoptera, to have the sin- 

 gular property of giving immediate and effectual relief in the most 

 violent paroxysms of tooth ach, by rubbing them between the 

 thumb and finger to the affected tooth. It proceeds from a larva 

 of disagreeable appearance, of a lengthened oval shape, with a 

 sharpened tail of a black* colour, varied with red and white specks, 

 and of a rough surface: it resides on various plants, and changes to 

 a short, blackish, oval chrysalis, spotted with red, which is meta. 

 morphosed to this beautiful insect in the month of May and June.
