the second molt are killed. Plenty of eggs, however, survive, and 

 some adults of both sexes. Sometimes half of the eggs under a scale 

 are killed. Nitidulid beetles iu 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 Rouge, La., that Aleyrudes 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 couUl 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 froin such a severe shock. Experiments will, however, 

 be conducted at the earliest opportunity to ascertain the eflect of appli- 

 cations under these conditions. 



Bulletin 33, Division of Entomology.— Bulletin 33 of this Divisiou, 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.
