of the plant, feeding chiefly on the pith. They are full-grown some 

 time in November, and the adults appear early in July. Pupation 

 probably occurs in May or early in June. The common ragweed 

 ( Ambrosia artemisiifolia) is an alternative food-plant. 



In certain localities about 10 per cent, of the foliage of strawberry 

 plants was destroyed by the Arctiid, Haploa colona var. reversa. Stretch. 

 The larvae appeared early in April and were nearly full-grown by 

 the 19th of the month. The Tenebrionid, Eleodes tricostata. Say, causes 

 serious damage in new strawberry beds. The larvae attack the crown 

 and the roots immediately below it. The adults appear late in July.

 Baits. — Jl. Econ. Ent., Concord, N.H., xiv, no. 1, February 1921, 

 pp. 138-141. 



As a result of experiments with materials that would possibly prove 

 more effective and cheaper than those now in use for grasshopper 

 baits, lemons appear to be the least attractive of the substances tried. 

 Salt was more attractive than lemons or oranges, and was just as effec- 

 tive alone as with the addition of molasses.. The most attractive 

 substance proved to be amji acetate. It has the additional advantages 

 of being cheap, ready for use, easy of transport, and of keeping indefi- 

 nitely. The experiments described were conducted against Camnida 

 pellucida, Scudd. Since the writing of this paper, amyl acetate has 

 been successfully tried on a large scale.

Anihonomus grandis var. thurheriae. Pierce, is recorded from the 

 cotton fields in Arizona. Though this weevil has previously been 

 noted on experimental cotton and as a potential cotton pest [i?. yl.f., 

 A, ii, 78, 272, etc.], it has not previously been recorded as attacking 

 this crop when grown commercially.
