escape) during the month of November (the living specimens were 

 received about the middle of that month) seems to me quite remarkable. 

 When the apj)earance of an imago that ordinarily requires a winter for 

 its development, is delayed beyond its normal time in the following 

 spring, as is not unfrequently the case with beetles, moths, etc, it is 

 usually extended to the spring of the year thereafter, when the grow- 

 ing plant is in readiness for oviposition and for larval food. Such 

 prolongation of the larval or pupal stages may, at times, serve for the 

 continuance of the species in view of possible unfavorable conditions 

 intervening, but a prolongation such as we interpret that related by 

 our correspondent, would seem to be necessarily fatal to the entire 

 delayed brood. 



Remedies. 



Any of the remedies named for Bruchus pisi would, of course, be 

 equally efficient for this species. The following method, given by a 

 coiTespondent of the New England Homestead, might be convenient 

 where a large quantity of infested peas or beans are to be treated. 



Take a large box — a common dry goods box will do — and line it 

 air tight with tin, leaving a round hole with a cover eight or ten 

 inches across. Put the beans or peas into this box through the hole, 

 and into a box that will hold eighteen to twenty-five bushels put 

 half a pound of chloroform, by pouring it on a cloth and shoving the 

 cloth down to the bottom with a stick. Then put on the cover tight 

 and let them stand five or ten days. This will kill all the grubs of 

 the weevil, which are in the beans. After this, you can sack up your 

 beans and have no more trouble from the weevil. The chloroform 

 leaves not the slightest taste or smell in the jieas or beans, and the 

 cost need not be over two or three cents per bushel. I have been 

 using the above recij)e for the last twenty years and my peas always 

 come out beautiful, and keep so if they are put in at once and as soon 

 as they can be threshed.

I have a young orchard of some four or five hundred apple-trees 

 just coming into full beai'ing, of select fruit. Part of these I noticed 

 last season showed signs of disease, the leaves turning quite yellow, 

 which at that time T attributed to the then prevailing drouth. I 

 notice that it is extending farther in the orchard this season, and is 

 cause for alarm. Upon investigation for the cause, I find the inclosed 

 beetles, which are secreted under the old bark, and where found their 

 abrasions extend to the wood, and a stain or discoloration as if caused
