similar habits (E. s. B., 29, i>. 468). Technical description! are given of the 

 several stages of this predator and brief notes on Its life hlstorj and habits. 



The parasitic enemies mentioned Include Aplettomorpha pratH, one of the 

 more common species, which is found In various localities from Richmond, 



Va., southward to Key West, Fla. A, cundiiui was found abundant in a tobaOCO 



warehouse al Clarksville, Tenn. 



The technical description of the larva of the cigarette beetle and of T. (/iro'li 

 are by A. (!. P.oving. 



The remedial measures considered at length consist of cold storage, high 

 temperatures, ultra-violet rays, trapping, exposure to vacuum, sealed con- 

 tainers for manufactured tobacco, casing cigar tobacco In a decoction of 

 tobacco stems, use of cold water in casing cigar tobacco, and boric acid. Fumi- 

 gation with hydrocyanic-acid pis, carbon tetrachlorld, carbon dlsulphid, and 

 formaldehyde and the effect of the Roentgen or X-rays are discussed at length. 



The more Important means of control of this beetle have been summarized 

 by the author as follows: "Scrupulous cleanliness in the factory, wholesale 

 or retail establishment, Including the prompt destruction or treatment of all 

 refuse material, damaged stock, etc., in which the beetles may breed, iii 

 factories, screening or otherwise protecting the finished product from infestation. 

 Constructing or refitting packing or storage rooms, especially in warm localities, 

 so that they can be quickly and easily cleaned, and with a view to the ex- 

 clusion of beetles which may be present in other parts of the factory. 



"Among the destructive agencies which may be employed in control of the 

 insect are freezing (treatment by cold storage or exposure to low temperatures 

 in cold climates) ; high temperatures or steam (a temperature of from 125 

 to 140° F. continued for several hours, or 150° for a short time, kills all stages 

 of the beetle) ; trapping or destruction by mechanical means; fumigation with 

 carbon dlsulphid, hydrocyanic-acid gas, or other fumigants ; and sterilization 

 of Infested tobacco by means of exposure to Roentgen or X-rays. 



" The modern method of storing leaf tobacco in hogsheads in specially con- 

 structed buildings or sheds, giving practically out-of-door conditions and varia- 

 tions of temperature, furnishes an effective means in cool climates of reducing 

 or preventing injury from the beetle to the classes of leaf tobacco which may 

 be stored in this manner."

A new species of Agrilus from Florida, W. S. F|sher (/'roc. Ent. Soc. 

 Wash., M (1918), No. $, pp. 67, 68).— Ay ri I us dozieri from Gainesville, Fla., is 

 described as new. It was found to be fairly abundant on the foliage of blue 

 birch (Ottrya sp.) about the first of April, 1917.

 unusually large crop of honey from alsike and white clover produced in On- 

 tario, Quebec, and Manitoba, principally due to the wet spring followed by 

 fine, warm weather when the plants were in flower. The highest yield of 

 honey iu 1910 was obtained at the Central Experimental Farm, Ottawa, where
