THE PEOPLE'S FARM AND STOCK CYCLOPEDIA. 



NATURAL HISTORY. The beautiful brown beetle (Fig. 25, c), 

 with its two stripes of white, appears early in June, and thence on 

 through July. So the egg-laying is principally done in these two 



months. The 

 grub (Fig. 25, 

 a) whitish, with 

 a round black 

 head, eats 

 through the 

 bark, and then 

 usually passes 

 in and up, fre- 

 quently eating through the branches far out toward the extremity. 

 I have frequently found apple-tree limbs no larger than my 

 thumbs, with a tunnel as large as a pipe-stem. These larvae 

 push their saw-dust like particles back of them and out of the 

 hole where they first entered, so that it is not difficult to find 

 them. They live and feed on the wood of the tree for three 

 years; hence, we see how that a single larva may bore, if left 

 undisturbed, for a distance of several feet. They finally bore a 

 hole for exit, fill it slightly with their sawdust, and a little back 

 of the same make a cocoon of their own chips, in which they 

 pupate (Fig. 25, b). Soon after, in June and July, the beetles 

 again appear. 



REMEDIES. Soapy mixtures are found to be obnoxious to 

 these beetles, so that in their egg-laying they are found to avoid 

 trees to which such an application has been made. Thus we 

 may hope to escape all danger by washing the smooth trunks 

 of our trees early in June, and again early in July, with soft 

 soap or a very strong solution of the same. T. T. Lyon, now of 

 South Haven, whose judgment is very reliable in such matters, 

 urges that we always use the soap itself. I have found the car- 

 bolic acid mixture, recommended for the radish maggot, undi- 

 luted even better than clear soft soap. Its obnoxious principle is 

 more lasting. We should always examine the trees carefully in 

 September, and wherever we find this pernicious grub's saw-dust 

 shingle out, we should give him a call. Perhaps we may reach
