the regular crop is set out; plant other trap seed when the regular 

 crop is put in; plant still other trap seed a week or ten days later; 

 keep the regular crop sprayed with arsenate of lead (3 pounds to 50 

 gallons) until the plants begin to run, then keep s]d rayed with Bor- 

 deaux mixture (3 pounds Copper Sulphate, 4 pounds of lime, 50 gal- 

 lons of water). 



From the very nature of these materials, it is evident that in a bad 

 beetle year, they would be insufficient to protect the plants. In such 

 cases, the only efficient method of protection is by means of covers. 

 Many forms have been invented, all either costly to purchase or to 

 apply, and some both. But the market gardener, who can secure high 

 prices for his prime cucumbers, can aff^ord to use them, so I will take 

 a few minutes of your time in suggesting what has seemed to us a 

 practical sort of cover. Secure yard-wide screen -wire of slightly 

 smaller mesh than the ordinary window screening, and cut off one 

 yard. The piece will then be one yard each way. Describe a circle 

 on this piece, having a diameter of 36 inches, and cut off the corners. 

 Then divide this circular piece of wire into two equal parts. Join 

 the cut edges by drawing them together and folding them over, ham- 

 mering them down firmly. Thus a cone-shaped wire cover costing a 

 few cents and capable of withstanding several years' usage is ready 

 for use. Two covers can be made from each square yard of wire. 



Mr. J. B. Smith suggested that the wire used for screens to protect 

 the plants must have a very small mesh. 



Mr. R. L. Webster asked concerning the parasites bred from Dio- 

 hrotica, and in reply jNIr. Headlee stated that they were Tachinids. 



Mr. Burgess inquired concerning the length of time that the adults 

 deposited eggs. He had been able to secure eggs for two successive 

 seasons from a female of Calosoma frigidum that had been kept in 

 captivity. To this Mr. Headlee replied that as far as he had observed, 

 the females of Diabrotica vittata deposited all their eggs in one 

 season. A. F. Burgess. Secretary 



UNIFORM COMMON NAMES FOR INSECTS 



By A. F. BuKGESs, WasMngton, D. C. 



At the sixteenth annual meeting of the Association of Economic 

 Entomologists held at St. Louis, Mo., in December, 1903, a Committee 

 on Nomenclature was elected to secure the adoption of uniform names 

 for our more common insects. In the past much confusion has re-
