324 PROCEEDINGS OF THE ACADEMY OF (June, 
Cnethocampa pinivora, eggs and larve; 
Fidonia piniaria, larve; 
Euproctis chrysorrhea, larve; 
Clistocampa neustria, pups and adults; 
Liparis salicis, pupe and adults; 
Pieris brassice, pupe and adults; 
Porthetria dispar, adults; 
Nematus abietum, larve; 
Nematus salicis, larve, 
were taken eagerly by captive birds, such as titmice, redstarts, 
kinglets, nuthatches, etc. Although the list includes hairy larve, 
some with urticating hairs, and sawfly larve which other experi-- 
menters state that birds usually reject, Dr. Rérig does not mention 
any refusals. We have already quoted his notes on the accept- 
ance of Pieris brassice, which has been classed as distasteful. 
Dr. Rorig’s birds also ate plant-lice, Aradus cinnamomeus, Cecidomyia 
saliciperda, Retinia buoliana, R. turionana, Phyllopertha horticola, and 
Scolytide. 
We may note here also the experiment” of Dr. Giinther in feeding 
Meloide to chickens. He fed the fowls from 1 to 5 grams of Can- 
tharus daily, until a total of 28, 28, 40.5 and 80.5 g. of the material 
was taken by four chickens respectively. One of the birds which 
ate 28 g. showed symptoms of poisoning; the others remained 
healthy. Significant amounts of cantharidin were recovered from 
the bodies of these birds, and even from eggs laid by them. 
Another German experiment but slightly related to the theory 
of protective adaptations is recorded” by Alexander Bau. The 
titmice, Parus major and P. communis, accepted in confinement 
eggs of Liparis monacha, Porthetria dispar, Orgyia spp., and Clisio- 
campa neustria (p. 69). 
Brief mention should be made of the following:

Quoted by Rev. Canon Fowler, to the effect that Clythra quadri- 
punctata, Gonioctena rufipes, and species of Lina were rejected 
by several species of British and foreign birds in the London 
Zoological Gardens. All of these beetles were eaten by a 
racket-tailed drongo.
