Boll Weevil Quarantine Regulations. — Georgia Slate Board of Entomo- 

 logy, Atlanta, Circ. no. 19, July 1916, 11 pp., 1 map. 



This circular contains the text of the boll-weevil quarantine regu- 

 lations issued by the Georgia State Board of Entomology under the 

 authority of the Georgia Quarantine Act, a copy of which is also given. 

 The boll-weevil line extends along the points where weevils were 

 actually found at the time of the first killing frost in 1915. The 

 inspections of the U.S. Bureau of Entomology in Alabama, Georgia 

 and Florida confirmed the correctness of this line. The safety line 

 is twenty miles and the quarantine line fifty miles in advance of the 

 actual boll weevil line. The position of these lines is shown in a sketch- 

 map. No person except the State Entomologist, or his authorized 

 deputy, may lawfully have in his possession outside of the weevil- 

 infested territory any living stage or any cotton square or boll con- 

 taining such stage, of the Mexican cotton boll-weevil [Anthonomus 

 grandis]. 



PoRTATE (F.). Per la Bianca-Rossa. [A note on Clirysomphalus 

 dictyospermi, Morg.] — Giorn. Agric. Merid., Messina, ix, no. 7, 

 July 1916, pp. 100-104. 



A decrease of infestation by ChrysompJialus dictyospermi has been 

 noted in Sicily. This must be due not only to applications of hme- 

 sulphur, but also to the action of natural enemies such as Chilocorus 

 bipustulatus, L., Exocliomus quadrijMslidatus, L., and Aphelinus 

 chrysomphali, Mercet, as reduced infestation has been observed in 

 citrus plantations where spraying had never been carried out. 



Dawe (M. T.). Memorandum sobre la enfermedad del arroz en 

 Villavicencio. [A note on a disease of rice in the Villavicencio 

 district.] — La Patria, Bogota, 2ith June 1916. 



Rice growers in the Villavicencio district of Colombia have noticed 

 that damage to their crop, which has been long prevalent there, has 

 assumed an epidemic character this year. The damage is done by a 

 small insect (so similar in appearance to a mosquito that it may be 

 called the " rice mosquito ") sucking the leaves of the rice plant. The 

 following petroleum-soap emulsion is advised : Hard soap, h lb. ; 

 water, 1 gal. ; petroleum, 2 gals. For use it must be diluted ^^'ith 

 eight parts of water.
