Show 1887.] VALUE OF COLOUR AND MARKINGS IN INSECTS. 269 August 12.-One Pygara bueephala larva was eaten, but this species generally allowed to crawl about the cage unnoticed. August 27.-An evil-smelling inconspicuous Hemipteron refused after tasting. August 30.-Lizards refused to eat the gooseberry sawfly. August 31.-Lizards ate common earwig and imagine., oi Tryphana pronuba, T. orbona, and Amphipyra pyramided. Sept. 5.-L. viridis $ killed, but refused to swallow a humble-bee (Bombus). Sept. 14.-Lizards ate imagines of Mamestra brassica, Pieris brassica, and P. rapa. Sept. 27.-Zootoca vivipara ate larva of Tryphana pronuba. Oct. 2.-Larvse of Tryphana arbona eaten, and imagines of Anchocelis pistacina seized and eaten greedily, but apparently swallowed with difficulty. Oct. 4.-All the Lizards refused the imago of Vanessa urtica. Mr. Jenner Weir also informs me that the common Muscidse were eaten with intense relish, their larvse and pupse being also eaten. APPENDIX II. E. B. Poulton's Diary of Observations during 1886. May 8.-About this date one larva of L. quercus was offered to L. muralis and L. viridis, but it was untouched, although allowed to remain many days in the cages. One imago of Pieris rapa was eaten. One imago of Dasychira pudibunda ( $ ) was seized and eaten directly it was seen to move (L. muralis). One larva of Mania typica was eagerly seized by two individuals of L. muralis, being detected while it was rolled up and motionless (feigning death). The larva was shaken and bitten, but it was not swallowed, and the Lizards rubbed their jaws upon the wooden floor of the cage, an evident sign of distaste. When the larva had been thus wounded another Lizard came up and inspected it closely as if it were going to bite, but soon retired without touching it. It seems probable that this last Lizard was warned by the smell of the larval fluids which had escaped after it had been wounded. Four pupse of Pygara bueephala were introduced (L. muralis) and were bitten, but at once relinquished with the signs of distaste described above. Earthworms were eaten with great avidity by all the species of Lizards. May 9.-Five imagos of P. rapa were eaten, two of them immediately. One imago of Pieris brassica was eaten at once, being pursued by two or three Lizards (L. muralis). Two imagos of Pieris napi were immediately seized and eaten. One imago of Trichiosoma lucorum was eaten at once by L. muralis. May 18.-One imago of Chloephora prasinana was seized and eaten the instant it was seen to move but not before (L. muralis). May 19.-One imago of Gonoptera libatrix was at once detected PROC. ZOOL. Soc-1887, No. XIX. 19 |
