I02 The BiUterflies and Moths of Teneriffe. 



repaid for their trouble by the result of experiments 

 in selecting and breeding together insects of the same 

 species which exhibit any slight deviation in their 

 markings and colour. Thus in rearing a number of 

 the Pyrameis Calhrhoe several specimens have been 

 observed to emerge from the chrysalis state with bright 

 yellow instead of red markings on the margins of 

 the hind-wings. The white markings on the upper 

 wings also varied somewhat. The Pyrameis family 

 would possibly lend itself freely to the production of 

 new varieties. The Danais Chrysippus is another species 

 of butterfly which presents itself for experiment. By 

 selecting the lighter hind-wing variety, Alcippoides, for 

 breeding, perhaps the Alcippus, which hitherto has 

 not been found in Teneriffe, might be produced. 

 Among the smaller butterflies, the Chrysophanus 

 Phlceas, and the Astrarche var. Aestiva have both 

 shown deviation in colour and markings, but these 

 are much smaller, and consequently more difficult to 

 rear. Moreover, they would not lend such an interest 

 to the subject as the larger specimens. 



In the moths, the Deilephila Tithymali caterpillars,
