MONOPHLEBUS STEBBINGII. I4f 
—— 

in April rgo1 by a looper caterpillar, the larva of the moth Boars 
mia selenarta, which entirely stripped the sdl trees of leaves, 
flowers and green shoots. 
Protection and Remedies, 
No natural enemies of this scale have been as yet observed 
attacking the insect in the forest.! 
Following the famous precedent of the introduction of a 
ladybird beetle into Florida to exterminate the fluted scale 
which was rapidly ruining the orange and citron industry by 
killing off the trees, I am endeavouring to obtain colonies of 
likely beetles of this family to introduce into the sal forests. 
Both Vedalia cardinalis and Vedalia fumida var. roseipennis 
will be experimented with with this object. 
Points in the life history requiring further observation =! 
1, When the eggs are laid, their number, and the time 
spent in this stage (see above). 
2. When the @ larva makes its first appearance. 
3. When the @ larva first appears, where it lives, 
what it feeds upon, and when and where it under- 
goes its transformations into the imago state. 
4. The number of generations in the year. 
5. In many of the forests where this scale appears, if 
not in all, the branches of the trees have curious 
knotty swellings on them. Are these swellings 
the result of the coccid’s attack, and, if so, how do 
they originate ? 
Is there any connection between these swellings and 
the method and position of egg laying by the 
females ? 
Is the second stage of the life history of this insect 
passed within the tissues of the bark, and are these 
swellings connected with this second stage ?

1 Since this note was written I have spent sometime further studying 
this scale which has been very abundant again this year (1902), Many new 
facts regarding its life history have been observed, not the least important of 
which being the discovery thatthe pestis most heavily preyed upon by a 
occinellid beetle and its larva.
