i-itory Next dav these were observed feeding on the Fseudococcus 

 in the same way that other specimens had been observed teodm 

 on the larva of Pulvinaria in 1905. 

 April 26th, and on several succeed- 

 ing days, more beetles w^ere seen 

 on the infested trees, but after 

 May 4th they disappeared and 

 were not again seen. 



On trees infested by Pidvinmna 

 no beetles were seen in New Bruns- 

 wick, but no very close examina- 

 tions Avere made, and as the in- 

 fested branches were well out of 

 reach and the lady-birds are very 

 active they might very easily have 

 been, and probably were, present. 

 On May 8th the lady-birds were 

 observed both at East Orange and 

 Montclair, but not in large num- 

 bers. In East Orange the work 

 of tlie shade tree commission, in 

 some places, and the work of the 

 beetle, in others, had reduced the 

 Pulvmaria to harmless numbers, 

 and in Montclair the beetle, sup- 

 plemented by the little parasitic 

 Coccopliagus, had wiped it out 

 almost altogether. In all the lo- 

 calities where examinations were 

 made the beetle had done good 

 work against the soft scale. 



In 1905 the beetle was but 

 rarely observed on trees infested 

 with Fseudococcus, but during 

 the present year it was observed 

 wherever this scale was seen, and 

 often the larva was found im- ' Fig. 24.

adult female, where it was as 



well concealed as in the Pulvinaria, but the pupae were not ^^o well 

 protected and undoubtedly occurred on the undersides of the 

 leaves and in similar situations.
