instances, but it will be sufficient to say, that we never 

 find the eggs of the small tortoise-shell butterfly 

 {Vamssn vrlicct:) on any plant but the nettle; its 

 congener, the painted lady {C'ljiilliia cardui, Ste- 

 phens), though it preteis the spear-thistle, is some- 

 times found on the nettle, as is the comma ( Va- 

 nessa C. Jllbum), though it seems to prefer the hop; 

 while we have found the eggs of the lackey moth 

 {Clisiocampa ntuslria) on almost every bush and 

 tree, from the swectbriar to the oak, in woods, 

 hedges, orchards, and gardens, without any apparent 

 preference beyond the accident of the mother moth 

 alighting on a particular branch. In the same way 

 almost all those which deposit their eggs on salad 

 plants, such as the great tiger {drciici Coja, Ste- 

 phens), will as readily select the nettle as the lettuce 

 or dandelion.* 



It is worthy of remark thr.t our native insects fre- 

 quently make choice of exotic plants, by means of 

 the instinctive tact which enal)les them to discover 

 such as suit their purpose. The death's-head hawk 

 moth [^iiliiyinilid Airopos), for example, is now 

 usually found on the potatoe and the jasmine, but 

 previous to the introduction of these into Britain, it 

 probably confined itself to the bitter sweet {Solamnn 

 dulcamai-(t). We have known the moth taken in 

 Ayrshire, where this plant is abundant.. An instance 

 in point has just occurred to us in one of the minute 

 leaf-miners. Upon the loaf of an exotic plant 

 {Cineraria cruenfa) kept in a garden-pot in our 

 study, we were not a little surprised to observe the 

 tortuous windings of a miner, considerably ditferent 

 in the outline fiom any we had before examined. 

 Thougii it was so late as Deceml)er, also, the grub 

 seemed ver) active, and would sometimes mine nearly 

 half an inch of the leaf in the course of the day. It
