The Tortricid moth, Eulia velutina, Wlk. (red-banded leaf-roller), 

 is a pest of beans, sweet potato, asparagus, strawberry, raspberry, etc., 

 that at times attracts considerable attention. It is a native of 

 the United States, where it enjoys a wide distribution from Maine 

 to Texas, and it has also been found in California. It breeds 

 continuously throughout the growing season, from April to November. 



In the District of Columbia hibernation takes place exclusively 

 in the pupal stage, which lasts five months. In June and July the 

 egg-stage lasted 11 days, the larval stage 22 days, and the pupal 

 a minimum of six days. There are at least two generations annually 

 and probably three where the climate is favourable. The various 

 stages are briefly described. 



Several natural enemies, mostly parasites, attack E. velutina. They 

 include the Hymenoptera, Exochus curvator, F., Epiurus indagator, 

 Wish., Lamprofiota pluralis, Cress., Limneriimi .sp., Opiiis foersteri, 

 Gall., Epirhyssalus atriceps, Ashni., Smicra delira, Cress., S. torvina, 

 Cress., Apanteles canarsia, Ashm., and a Tachinid fly, Phorocera 

 parva, Big. 



Artificial measures are seldom warranted, but a spray, containing 

 2-3 lb. of lead arsenate to 50 U.S. gals, water, may be applied when 

 the caterpillars are feeding. The best time is soon after oviposition. 

 In cases of slight infestation the webbed leaves may be crushed by 

 hand, or they ma}^ be clipped and burned. Early autumn ploughing 

 and burning over the garden after the crop is off, either in autumn or 

 early spring, will greatly help to keep this pest in check. 



Tower (D. G.) & Fenton (F. A.). Clover-leaf Weevil— ?:^S. Dept.

All stages of Hypera punctata (clover-leaf weevil) are described. 

 This weevil oviposits in or on clover or lucerne. The eggs laid previous 

 to 25th October hatch the same autumn, and the larvae hibernate ; 

 those laid later hibernate as eggs and usually hatch in March. After 

 feeding on the foliage the larvae spin cocoons at or just below the 

 surface of the ground, pupate, and give rise to the adults in June or 

 July. The beetles feed on the foliage of clover intermittently until 

 September, when they mate, and soon afterwards oviposition begins. 

 Since the period of oviposition extends over a number of weeks, and, 

 furthermore, eggs laid late in the season do not hatch until spring, 

 the various stages greatly overlap. 



Details are given as to oviposition, the habits of the larvae, and the 

 feeding experiments made to ascertain the amounts of clover foliage 

 eaten by H. ptindata at different seasons and during the larval and 

 adult stages. The amount eaten by individual larvae averages 3-09 

 square inches of red clover foliage, and of this amount approximately 

 80 per cent, is consumed during the last instar. 



The life of the adult is divided into two distinct feeding periods, 

 separated by one of inactivity during July and August. Beetles 

 deprived of foliage immediately after emergence die within a few days. 

 Adults emerging late in May become dormant late in June, while
