INSECTS AFFECTING PARK AND WOODLAND TREES 5 I 7 



below ; a row of punctures is made on each side of the midrib of the sev- 

 ered portion, which facilitates folding the leaf together, upper surface 

 inside, after which the'folded leaf is tightly rolled up from the apex to the 

 transverse cut, bringing the egg in the center ; the concluding operation is 

 the tucking in and trimming off the irregularities of the ends. A few days 

 after completion, the cases, first observed the latter part of April, dropped 

 to the ground; by May 15 several larvae hatched and fed on the dry sub- 

 stance of their nest, and by the end of May they pupated within the nest ; 

 this state lasted from five to seven days, the first beetles issuing by June 2, 

 while a second brood of larvae may be found early in July. The above is 

 based largely on Dr Packard's account. 



New York weevil 



ItJiycerns noveboracensis Forst. 

 A large, grayish weevil about ]/z inch long, occurs on the buds of a variety of trees 

 from May to July. 



This giant weevil is of interest on account of its large size, it not being 

 exceeded in dimensions by any of our native species. 



Description. The head is prolonged into a short, rather stout, slightly 

 tricarinate beak tipped with a pair of large jaws, eyes reddish. The head 

 and prothorax are coarsely punctured and rather thickly clothed with a yel- 

 lowish and white pubescence. The wing covers are deeply striate and are 

 also rather thickly clothed with a yellowish and whitish pubescence and 

 each bears a series of about 10 rather inconspicuous circular brown spots. 



Life history and habits. This large weevil has been recorded on the 

 twigs of oak, hickory and a variety of fruit and forest trees. Mr Harring- 

 ton considers beech as a favorite food plant for both larvae and beetles. 

 He has met with weevils in early June and two or three days later failed to 

 find any specimens on the same tree, concluding therefrom that the beetles 

 were abroad during a very limited time. We have taken specimens 

 in New York July 19, and as they also occur in May and June, this 

 would seem to indicate that adults might be abroad during an extended
