the Edihility of certain Lepidoptermts Larvae. 475 



September 3. — One lizard ate three blue-bottles and a 

 F. rajyae. The other one ate a green caterpillar (probably 

 Hadena olera(xa). Neither would touch a larva of rhom- 

 hoidaria. Later on the first lizard ate another P. rapae, 

 and the second ate two brownish-green larvae taken off 

 chrysanthemum plants. 



September 5. — Lizards had nothing to eat yesterday. 

 This morning one of them ate a blue-bottle, and I then 

 offered it a larva of rhomhoidaria. It seized it by the 

 tail and held it in its mouth for a short time, then worried 

 it furiously. As soon as it got a little more into its mouth 

 it dropped it and began rubbing its mouth violently on 

 the floor of the cage. Afterwards it would not look at it 

 again. The larva was still alive and the other lizard came 

 and looked at it, but either smelt it or recognized its 

 appearance, as it would not bite it. The first lizard 

 immediately afterwards ate a "blue-bottle," and about 

 two hours later a small earthworm. The manner in which 

 it swallowed these was very different to that in which it 

 treated the caterpillar. There was no hesitation, and the 

 worm was gulped down very rapidly. 



(Note. — These lizards ate larvae of P. hrassicac but 

 slowly, and as though not greatly appreciating them.) 



Later in the day one lizard ate four " blue-bottles " and 

 a P. ra'pae. The salamander ate three bees. The lizard 

 snapped up a bee but dropped it again suddenly, as though 

 stung, and would not look at another. 



September 7. — Lizard ate two "blue-bottles," a brownish- 

 green larva from the chrysanthemums, and a "gamma" 

 moth. 



The other lizard ate a larva of rhomhoidaria which had 

 been fed on apple for two days. While it was eating it 

 the other lizard chased it round and round the cage. 

 A second apple-fed larva was refused by both lizards. 

 Later on one lizard ate a worm but tasted and refused a 

 wood-louse. 



September 8. — First lizard would not look at an apple- 

 fed rhomhoidaria larva, but the other one ate it, rather 

 slowly at first. An ivy-fed one was then offered, but 

 neither lizard would touch it. The first lizard then ate 

 two " blue-bottles." 



September 9. — Five more lizards arrived. 



One of the original pair ate an ivy-fed caterpillar with 

 some hesitation, afterwards drinking water. One of the
