APPENDIX D. 



The " Deilephila Daucus," allied to '* Lineata," a 

 North American species, is said to occur in Teneriffe, 

 but the author has not seen a specimen. If such a 

 species is really found in the island, it is more probably 

 D. Livornica, whicb is common in South Europe and 

 throughout Africa, and is found in Madeira. Either 

 of the above species may be distinguished from D. 

 Tithymali by the white lines on the wings, but D, 

 Livornica has only four longitudinal white stripes on 

 the thorax, whereas D. Daucus has six. D. Livornica 

 is a rarity in England, but is found throughout all 

 the warmer parts of the Old World.
