Locusts in Buenos Ayres ( Weekhj Xortli Western MiUer, 4.? (1S97) Xo. 11, p. 3S7). 



It ia reported that the Congress of Buenos Ayres hiis ajipropriated $700,000 to be 

 divided among the provinces of Santa, Fe, Entre Kios, and Cordova, which have suf- 

 fered severely from locust invasion and drought, and to be used for furnishing seed 

 for the colonists who have lost everything. The Congress has also appropriated 

 $400,000 for the scientific study of the insects and to learn their haunts. They are 

 supposed to winter in the Grand Chaco. A committee of leading merchants has also 

 been formed to deal with the subject, and subscriptions have beeu collected with a 

 view to employing some well-known entomologists.

 The author thinks it would be unfair to impose a proliibitory tariff on Mexican

 insect. 



The white fly {Florida Farmer and Frnit Grower, 9 {1897), No. 1464, p. 131).— A 

 series of five letters referring to the occurrence of the white tiy in an orange grove. 

 The trees were saved from freezing during the severe winter of 1895, and along with 

 them a great number of white Hies, which are now on the trees in masses. The 

 writers think it advisable for the trees to be bought by interested persons and burned.

 grow as a means of destroying the worms. One hundred worms were placed in a

Notes on forest insects, Nitsche ( Tharand J'orst. Jahrb., 46 {1896), II, pp. 225-247,

 manner of leaf feeding of Phyllohius psitlacinns is noted and <onipared with that of 

 certain Chrysomelida- and of lepidopterous larva', with an endeavor to show that the 

 species of insect can be determined from its manner of feeding. The report of the 

 work of destroying the gypsy motli, by Forbush and I'ernald, is reviewed at length 

 and exception taken to the use of the generic term Porthotria instead of Liparis of
