180 THE BUTTERFLY VIVARIUM. 



I would recommend the young curator of an 

 Insect Vivarium to try his luck each season in the 

 rearing of this splendid Moth from the Caterpillar 

 state, as it is the only way of procuring really fine 

 specimens of the perfect insect, which, if of unusual 

 size, Avould cost something like a guinea each, hut 

 which may thus be added to a collection at the cost 

 of a little care, and the gain of much instruction 

 and amusement. 



The Caterpillars of the genus Deilephila, also of 

 the Sphingidce, or Hawk-moth family, must be dili- 

 gently sought for, especially those of the beautiful in- 

 sect Deilephila Euphorbia (the Spotted Hawk-moth), 

 which in certain seasons have been found so plenti- 

 fully on some' parts of the coast of Devonshire as to 

 attract birds from a distance to feed upon them. 

 They are very conspicuous, both for their size and 

 colour, and feed upon the Euphorbia Paralias, or 

 Sea-spurge, which grows in great abundance in 

 the neighbourhood of Barnstaple. Mr. Raddon, 

 the well-known eminent engraver, who was also an 

 enthusiastic entomologist, published at that time an 

 interesting account of this larva in all its stages, 

 accompanied by a fine illustrative plate. Mr. 

 lladdon states that in 1814 these Caterpillars were 

 so plentiful in the neighbourhood just referred to,
