unti] October ; those of the second generation appeared about 

 20th August. A few eggs are laid by these adults, but the resulting 

 nymphs probabl}' perish before becoming mature. The last adults 

 were seen in November. 



In Kansas lack of food and cold are the principal checks on this pest. 

 Artificial remedial measures include cultural methods, hand-picking 

 of adults and eggs early in the season, and spraying. 



Of various contact insecticides tested, fish-oil soap (| lb. per U.S. gal.) 

 with sulphur (1 to 2 oz.) proved the most effective. Care must be taken 

 to keep the sulphur in suspension. Spraying should be postponed until 

 the nymphs are numerous. Under 1918 conditions the cost of spraying 

 amounted to about £5 per acre.

 in which Pyrausta nuhilalis, Hubn., reached America. — Jl. Econ. 

 Entom., Concord, N.H., xiii, no. 5, October 1920, pp. 425-430. 



The first record of the presence of Pyrausta nuhilalis, Hb., in America 

 was from specimens reared from Dahlia stems in Massachusetts in 

 1916, the site of infestation being close to two broom factories. From 

 the data collected with reference to the importation of broom corn 

 [Andropogon sorghum technicus] this crop appears to be the vehicle, in 

 which P. nuhilalis reached the continent.

 xiii, no. 5, October 1920, pp. 430-431. 



The bean Coccinellid, Epilachna aorrupta, Muls., is recorded from 

 Alabama, where cowpeas have proved to be an alternative food-plant. 

 This beetle was probably introduced in either lucerne or beans grown in 

 the infested territory in Arizona, New Mexico and Colorado. As it 

 is able to withstand ordinary climatic conditions of both winter and 

 summer, its spread throughout the south-eastern States is to be feared. 

 Investigations into the life-history and remedial measures in the 

 field have already been started.

Attention is drawn to the occurrence of Popillia japonica (green 

 Japanese beetle) in Pennsylvania. The source of the infestation is 

 not known.

 432-433. 



Adults of Saperda Candida are recorded as injuring apple fruits in 

 Pennsylvania. Under laboratory conditions, if conhned exclusively 

 with apples, these beetles will also oviposit on the fruits.

The flea-beetle, Nodonota puncticollis, Sa3^ has caused considerable 

 injury to apples in Pennsylvania by feeding on the fruit and occasionally 

 also on the leaves. It was first noticed on 2nd June and was \'ery
