bers in the plums of two old plum trees in a corner of one of our apple 

 orchards. In the past season the plums on those two trees failed completely 

 and the apples on the neighboring trees only were badly injured by the 

 beetles. In this region at least the curculio much prefers the plum to the 

 apple, and a few plum trees in the apple orchard would attract the 

 majority of the beetles present. The wormy plums from these trees should, 

 of course, be completely destroyed. 



The Apple-tree Borers (Saperda Candida and Chrysobothris femorata) 

 were locally injurious, as usual. 



The Round-Headed Apple-Tree Borer (Saperda Candida Fab.) : a, larva, from side; b, from above; c, female beetle; d, pup^— 

 all enlarged one-tlUrd. (From Chittenden.) 



The plum curculio (Conotrachelus nenuphar^; a, larva; b, adult; c, pupa, Much enlarged (hair line to right of b indicates 

 natural length of adult) . (From Chittenden.) 



The Bud Worm, the Case-bearers, and the Canker-worms have not been 

 injurious in this neighborhood. The Apple Aphis caused less trouble at 

 the College than usual. The trees were thoroughly sprayed early in the 

 season with lime sulphur wash, and this, apparently, destroyed many of the 

 aphis eggs.
