rence, and life history. Eggs deposited in May liatched in 9 days, the larval 

 stage requiring 25 days and the pupal stage 11 days. Experiments conducted 

 and here reported indicate that arsenate of lead is an excellent remedy. D. 

 vittata is usually rare in southern Texas (as compared with D. balteata) audits 

 injuries are confined to cucurbits. It was found that eggs deposited early in 

 May hatched in 8 days, that the larval stage required 14 days and the pupal 

 stage 5 days, making a total of 27 days for development from egg to adult. 

 D. duodevimpunctata occurs only in small numbers in southern Texas. Eggs 

 deposited in May hatched in days, 15 days were passed in the larval stage and 

 6 days in the pupal stage.

Some enemies of rhododendron, A. Naumann (Jahresber. Ver. Aiigeic. Bot.,

Bules and reg'ulations for carrying' out the provisions of the insecticide 

 act of 1910 (17. H. Dept. Agr., Office See. Circ. SJf, pp. l.'t). — The rules and regu- 

 lations here promulgated relate to " the collection and examination of specimens 

 of insecticides, Paris greens, lead arsenates, and fungicides manufactured or 

 offered for sale in the District of Columbia or in any territory of the United 

 States, or which shall be offered for sale in unbroken packages in any State 

 other than that in which they shall have been respectively manufactured or pro- 

 duced, or which shall be received from any foreign country or intended for ship- 

 ment to any foreign country, or which may be submitted for examination by 

 the director of the experiment station or any State, territory, or the District 

 of Columbia (acting under the Secretary of Agriculture), or at any domestic 

 or foreign port through which such product is offered for interstate commerce 

 or for export or import between the United States and any foreign port or 

 country."

Grease banding' of fruit trees, F. V. Theobald (Jour. Bd. Agr. [London], 17 

 (1910), No. 7, pp. 5Jf2-552). — Experiments and observations made during a 

 period of 6 years are here reported upon. 



"Of the 3 classes of greases experimented with, namely, (a) yellow and 

 white, (b) the black German moth glues or raupenleims, and (c) greases of 

 birdlime type, or tanglefoot, it was found that the first dries too quickly, the 

 second has a low catching power, but that the third lasts ' tacky ' for well over 

 the period of attack, and by moving it with a piece of wood, is at the end of 



10 to even 15 months nearly as ' tacky ' as before. The black greases do not 

 seem to attract insects to the same extent as the white and yellow and shiny or 

 birdlime preparations."
