MISCELLANEOUS INSECT NOTES. 335 



the south side of the tree were dead and leafless. Otherwise 

 the tree appeared perfectly vigorous and the foliage was of a 

 dark green color. Finally a few leaves were observed that did 

 not look quite healthy, and they were found to be infested with 

 the pine leaf scale Chionaspis pinifoliae Fitch. Some branches 

 were considerably infested, and the dead ones may have been 

 killed in this way. It was certainly difficult to find any other 

 explanation. This insect was mentioned in Bulletin 151, page 

 II, and in the report for 1905, page 240, and shown on Plate 

 II, c. It resembles the scurfy scale, and is found on the leaves 

 of pine and spruce trees. It is becoming rather comnion in Con- 

 necticut, and has been observed on white pine se£41ings at 

 Windsor the past season. It has also been sent in from various 

 parts of the state on other species of pines from cultivated 

 grounds. I have seen no record of its occurrence on hemlock. 

 The remedy is to spray with kerosene eniulsion soon after the 

 eggs hatch. 



Willow Curculio. In Massachusetts, New York and Minne- 

 sota the willow curculio, Cryptorhynchus lapathi Linn., causes 

 considerable injury to ornamental willow and poplar trees in 

 parks and on private grounds. Previously, however, the insect 

 has not been very common in Connecticut. On July 7th, 1905,

the writer collected a specimen of this beetle from a bunch of 

 native willows {Salix discolor) at Torrington. The willows 

 had been tunneled through and through by this insect, and 

 though of no value, were ruined. In 1906, another species of 

 willow at Guilford was observed to -be likewise injured by this 

 beetle. During 1907 several bunches of willows near New 

 Haven have been killed outright by its attack. This beetle is 

 one of the snout beetles or curculios, and is shown in Figure 5.
