66 THE ENTOMOLOGIST. 



my correspondents have done. If the trap is made accordmg to 

 my dh-ection, and the place is suitable, success sooner or later is 

 a certainty. The principal thing is to select a suitable place. I 

 have had all my best catches by setting the trap on the edge of 

 a wood bordering a large heath, and now always keep a trap set 

 there. It is not set so that the light goes over the heath, but 

 facing along a glade near the edge of the wood, and running 

 parallel to the heath from west to east. I cannot say why, but I 

 have had all my best catches with the trap facing east. I have 

 another trap, which I keep moving about, setting it in other 

 spots which appear likely ; and yet sometimes, on nights when 

 the first trap has had a large catch, the second trap, often 

 set within a quarter of mile, has had nothing, though set 

 in a place to all appearance equally or even more likely. 

 Hence it seems tolerably clear that a great deal depends on 

 hitting on the right place. My experience is that, until you 

 have given it a fair trial, you cannot tell whether a place is good 

 or no. I always place the trap on a table, about two and a half 

 feet high. I have tried various elevations, and I find this as 

 good as or better than any. I would not recommend anyone to 

 paint his traps white, as one of my correspondents has done, 

 as that is calculated to affect the light proceeding from it ; nor 

 indeed to paint them at all, which, with the zinc covering, is 

 quite unnecessary. I find it very little use to set the trap on 

 moonlight or frosty nights ; but wet, gusty ones I have found 

 very good. 



With these preliminary remarks, I will proceed to my list : —

 dusk, and the insect was there when the trap was visited before sunrise
