its eggs shortly thereafter. Prof. Webster states that in a serious 

 attack observed and studied by him of the insect on the dewberry 

 (Rub us Canadtnsis) in Southern Ohio, where the culture of this berry 

 had developed into an important industry, it was learned that the 

 beetles appeared about the middle of May and remained until the last 

 of June or about the time of the ripening of the first berries.* 



Dr. J. B. Smith, who represents it as a chief pest of the blackberry 

 in New Jersey, gives for the time of the emergence of the beetle from 

 May 20 to July 10. He is of the opinion that the egg is not inserted 

 in the tissue of the cane as generally stated, but is simply laid at the 

 base of the leaf-stalk or in the bud. See the interesting account 

 by him of the peculiar burrowing operations of the larva as given in 

 Insect Life, iv, 1891, p. 28. 



Notwithstanding occasional instances of such extensive infestation as 

 above noticed, the beetle seldom falls into the hands of collectors in 

 New York. The only examples (2) taken by me were captured in 

 Schoharie, N. Y., over thirty years ago, probably in my garden. 



This insect has been previously noticed in my sixth report, pp. 123- 

 125, where its transformations are briefly given, the gall that it pro- 

 duces figured and some literature cited where fuller details maybe 

 found. 



Its Distribution. 



Dr. Horn, accompanying his detailed description of the beetle in 

 " The Species of Agrilus of Boreal America,"! has given the following 

 as its distribution: From Canada and the New England States south- 

 ward to Virginia and westward to Missouri. 



Respecting Agrilus anxius. 

 The Agrilus torpidus Leo, mentioned in my fifth report as taken in 

 large number from cut poplars at Elk Lake, Essex county, N. Y., in 

 the latter part of August, 1883, had been described by Gory in ?1835 

 as Agrilus anxius : torpidus, therefore, becomes a synonym. Its range 

 is said to be from Massachusetts and New Hampshire westward to Col- 

 orado. Mr. G. C. Davis has found it producing galls in branches of 

 the willow (Salix discolor) in Michigan. The gall is an oval swelling, 

 from which an oval gallery is bored downward, sometimes in the pith, 

 but oftener through the wood, opening outwardly an inch and a half 

 below the gall (Insect Life, iv, 1891, p. 66).
