the second molt are killed. Pleuty of eggs, however, survive, and 
some adults of both sexes. Sometimes half of the eggs under a scale 
are killed. Nitidulid beetles in decaying fruit were all killed. In the 
flowers of Aulocasia and Brugmansia multitudes of small gnats were 
frozen. Not a living colony of plant-lice upon orange or other trees 
could be found. 
But the insect which seems to have been most effectually damaged 
is the white fly, Aleyrodes citri. Mr. Hubbard could not find a living 
specimen, up to the date of writing. They were killed wholesale, 
and there were plenty of them in all stages upon the younger leaves of 
citrus plants. As the eggs are laid upon the leaves normally, and 
every leaf will drop long before the new growth appears, it seems that 
the cold wave may have seriously checked this pest. The only condi- 
tions under which it will have survived will be in the case of eggs 
which may have been accidentally laid upon the bark, Mr. Hubbard 
has, however, been unable to find any. Mr. Schwarz observed in 
August at Baton Eouge, La., that Aleyrodes citri occurs upon the 
Cape jasmine, but not on the few orange trees grown at that point 
and later observations by Mr. Hubbard show that there has been a 
survival of the white fly upon the former plant. He is therefore urg- 
ing Florida orange growers to cut down and burn their Cape jasmines. 
It is unfortunate that this condition could not have been produced 
without the corresponding damage to vegetation. As it is, however, 
the severe shock which the trees have received will put them more than 
ever at the mercy of injurious insects. An important point is sug- 
gested by Mr. Hubbard, namely, that as the breeding of nearly all the 
injurious insects of the orange has been completely suspended, for 
some weeks at least, there will be an excellent opportunity, with the 
advent of warm weather and the revival of vegetation, to completely 
clear the trees of scale and some other pests, with the aid of compara- 
tively mild insecticides. Orange growers will naturally be timid about 
applying any wash to their trees while they are in the critical period 
of recovery from such a severe shock. Experiments will, however, 
be conducted at the earliest opportunity to ascertain the effect of appli- 
cations under these conditions. 
Bulletin 33, Division of Entomology.— Bulletin 33 of this Division, which 
has just been issued in small edition, is a compilation of the laws 
which have been adopted in the United States and British Columbia 
against injurious insects. It also includes the laws of New York and 
Utah against foul brood in bees. The publication of this bulletin at 
this time has been thought desirable because of the prominence which 
the question of legislation against insects is assuming, and because 
many horticultural societies will desire to draw up bills for the con- 
sideration of State legislatures.
