le to learn of the habits of this bird, however, we are inclined 
to think that it is attracted rather by the abundant secretion of hone ey- 
eim and the minute insects caught in it than by the seale-insects them-

was seen to feed upon the adult insect, although commonly attracted by 
the honey-dew secreted. 
Among the predaceous insects found by Mr. Koebele and sent us 
for study we may mention first the larva of a small moth (Blastobasis 
icerycella n. sp. Y although as yet we are not certain that it ordinarily 
preys upon the living and uninjured siéde-inacs or their eges. Bigs 
certain other so-called predaceous Lepidoptera, it may ed

time previously, but never upon fresh eggs. One of the larvæ, kept i

mass, but did not thrive until after the sales died. It then fed upon 
the dead seales and moulted, but died before transformin g. Two nearly

this insect is often met with among the scales, and, from oe
