insects begin feeding, it is evident that quince growers should watch 

 closely for the first feeding punctures and be governed accordingly 

 unless they prefer to make three applications, one just after blooming, 

 a second about 2 weeks later and the third the latter part of July, or 

 in other words, give practically the same treatment as the usual three 

 sprays advised for the control of the codling moth. Usually the 

 first would be too early to secure the best results and the second 

 might well be delayed a little longer ; otherwise it may be washed off 

 before the insects feed to any extent. The ideal is to give the first 

 treatment just after the curculios issue, making a second application 

 a week later. 



Magdalls barbicomis Latr. A few specimens of this insect were 

 received July 9, 191 7, together with samples of their work on quince 

 from L. F. Strickland, Lockport, N. Y. The first sending was sup- 

 plemented by a considerable series of beetles and samples of their 

 work, July 12, 19 18. This small, black weevil is a European species 

 which has been recorded from Staten Island, N. Y., and Dorchester, 

 Mass., feeding on elm in the latter locality. 



The weevil gnaws irregular skeletonized areas on quince, the 

 eating being on the underside of the leaf and consisting of excavations 

 of the more tender tissues between the veinlets. The affected areas 

 soon turn brown, are irregular and may vary from small spots with 

 a diameter of approximately a twenty-fifth of an inch to diverse 

 shaped areas, with a major diameter of one-half of an inch to an inch. 

 Mr Strickland states that out of a total of 464 leaves examined, 156 

 exhibited injury of this character. The writer has noted similar 

 work in earlier years upon quince trees in different parts of the State 

 and there is a fair probability at least of the damage being caused 

 largely if not entirely by this introduced insect. 



Thorough spraying the last of June or early July with arsenate of 

 lead would very probably protect the foliage if it did not destroy 

 the weevils. 



Raspberry Byturus (Byturus unicolor Say) . Injuries by 

 this pest in Milton and Marlboro continued the present season and 

 in the judgment of one grower some 25 per cent of the crop is fre- 

 quently lost through the work of this insect, although many growers 

 attribute the shrinkage to something else or accept it as one of the 

 inevitable developments. 



The most satisfactory method of controlling this species is by early 

 and heavy applications of arsenate of lead, using 8 pounds of paste 

 to 100 gallons of water and spraying before the beetles have inflicted 

 material injury. The beetles feed upon the unfolding leaves or
