the plant, and later a campaign was undertaken for the destruction of 

 the scattered plants and seedlings growing beside the lands washed by 

 the floods. In 1920 an inspection service was initiated, which resulted 

 in the discovery of live areas of cultivated cotton in the Rillito 

 district that were infested with A. grandis var. thiirberiae. In order 

 to suppress, if possible, this infestation, the crop was picked, but the 

 seed cotton was left in the infested fields, which were put into quaran- 

 tine. Immediately after picking the plants were cut down, the 

 fields thoroughly raked, and the fallen bolls burnt. After all other 

 cotton had been ginned, the quarantine cotton was ginned separately, 

 the seed kept separate, crushed and returned to owners for stock food, 

 the lint was baled and the premises placed in quarantine. The gin 

 was then taken to pieces and cleaned throughout, including the 

 receiving-house, screens and all apparatus. All such cleanings were 

 burnt. 



Certain areas in the Tucson district have been set aside as non-cotton 

 zones. Future legislation in California with regard to cotton will 

 depend entirely upon the success obtained in Arizona with the remedial 

 measures now in force.

 Rice in the Philippine Islands. — Mthly. Bull. Cal. Dcpt. Agric, 

 Sacramento, x, no. 4, April 1921, pp. 159-160, 3 figs. 



Droyopeia hirsnta, sp. n., is described from the Philippines, where it 

 lives on the roots of rice and does considerable damage to the crop. 

 No alate forms were obtained, but the apterous individuals are quite 

 distinct from others in this genus. This new species is closely related 

 to D. bella, Koch.

Ceroplastes argentinus, sp. n., is described from grasses. A Chalcid 

 parasite, Prorkopoidcus haezi, gen. et sp. n., was reared from it.

An account is given of the usual remedial measures practised 

 against these important vine pests, the information given being con-

 Parma, xxvi, no. 17, 29th April 1921, pp. 241-242. 



The best treatment against vine moths [Clysia anibiguella and 

 Polychrosis botrana] consists in a spray of lead arsenate before flower- 

 ing, and one or two of nicotine after flowering for the second generation ; 

 these latter may be combined with lime-sulphur. Other measures, 

 such as dusting with lime, collection of the moths, cleaning the stocks 

 in winter, and shelter-traps, are also worth consideration.
