twigs lying on the ground, and that doubtless the oak-pruner often 

 falls a prey to these sagacious and diligent foragers. 



Mr. Lyman had also observed this present season, at Waltham, 

 Mass., where there are many oaks, the same ravages of this insect as 

 at his home at Bellport, L. I. He had cut open the burrows of many, 

 at Waltham, and had found the grub in most, but it seemed to differ 

 from those at Bellport, in being larger, longer, having a less pointed 

 tail, and a square, blunt head. 



He also noticed that some of the twigs, unmistakably cut off by the 

 grub, had no burrow in them, but only a shallow pit of the diameter 

 of a burrow on the severed surface, raising the question, in his mind, 

 whether the grub did not sometimes lose its direction and burrow 

 downward toward the trunk instead of from it. 



OviposiTioN OF Sapeeda CANDIDA Fabr. 



The following notes, condensed from a communication made by 

 E. W. Junkins, of Carroll Co., N. H, to the Neiv England Homestead, of 

 January 3, 1885, are of value as an addition to our knowledge of the 

 habits and life-history of the destructive round-headed apple-tree 

 borer, Saperda Candida : 



A part of a trunk of an apple tree that had been killed by the 

 borers and taken within doors in the early spring, showed, through a 

 crack opened by drying, a pupa of the beetle, on May tMentieth. On 

 June eighth it had changed to the beetle (indicating a pupal period 

 of at least nineteen days). Four other specimens that afterward 

 emerged were inclosed in a large glass jar containing wet sand at the 

 bottom, into which were thrust some shoots of an apple tree. The 

 beetles fed upon the tender bark. On June fifteenth, one of the four 

 females was seen depositing an egg. " She first made an incision in 

 the bark close to the sand; then turning head ujDward, with her ovi- 

 positor she placed the egg under the bark nearly a quarter of an inch 

 from the incision, the bark having been started from the wood. July 

 seventh a young borer, three-sixteenths of an inch long, made its 

 appearance. July eleventh, the sticks near the sand were full of eggs, 

 and the beetles were depositing their eggs higher up on the sticks. 

 July eighteenth, one of the borers, three-eighths of an inch long, had 

 worked an inch and a half downward. August seventh, the last beetle 

 died, but would doubtless have lived longer with better care." 



On the twenty-sixth of August a beetle was captured among the 

 branches of an apple tree, in the trunk of which eight young borers
