demonstrates the value of remedies, Avliic-h are more eflfective when 

 the insects are not overabundant, and should then be ])racticed as 

 a means of limiting injurious occurrences in the innnediate future. 

 The article entitled " Collective Notes on the Behavior of the Colo- 

 rado Potato Beetle in Great Britain " indicates that this Ameri- 

 can insect does not now exist in England, but that it is capable of 

 flourishing to a remarkable degree on the Continent. Some interest- 

 ing facts in regard to the use of hydrocyanic-acid gas as a remedy for 

 indoor insects have been gained during the year, a portion of which 

 are embodied in an article and a note in this series. During the -year 

 Mr. Frederick Maskew, of California, has cooperated with this office 

 in several investigations, two of which are made public — one on the 

 subject of Fuller's rose beetle and the other on the success of an intro- 

 duced ladybird beetle. Among general notes are short accounts of a 

 very injurious caterpillar enenw of velvet bean in Florida, an instance 

 of the complete destruction of the imported cabbage worm by para- 

 sites, and other notes of minor interest.
