COTTONY CUSHION SCALE. (Icerya purchasi Mask.) 
Louisiana H. K. Plank. (May 12): .The increase of this pest at New Orleans 
during the past fall and winter was sufficient to cause general 
$Iarm, and fear was entertained by some that the infestation 
would approach the seriousness of that of 1915-1917 » when numer- 
ous other plants than P itt osporum tobira . Plumbago sp. , Ulmus 
sp. , Ficus pumila , and Magnql ia g randif lora . were heavily 
infested and considerably injured before Nov ius cardinal is could 
be satisfactory; colonized.. However, since the finding of larvae 
of the Novius at work on numerous infestations throughout the 
city on February 3» 19^5» and subsequently, the abundance of the 
cottony cushion scale has, been so reduced that it is now very 
difficult to find any live adults anywhere in the city. The injury 
to the hosts mentioned has therefore been comparatively slight.
