individual. It is well, also, to bear in mind that almost without excep- 

 tion the other moths which are thus captured are more or less injurious 

 to vegetation. 



We will here illustrate some of the more practical moth-trap lanterns 

 which have been patented. 



There have been a large number of moth-traps patented, which are 

 made upon the plan of placing 

 a light above a pan containing 

 fluid, which may be either viscid 

 or poisoned. The moths at- 

 tracted by the light fall into the 

 pan, and are thus destroyed. 



The following figures and de- 

 scriptions illustrate a number 

 of the more simply constructed 

 and more practical of these in- 

 ventions. 



The patent of B. F. McQueen, 

 No. 166, 124, July 27, 1875, con- 

 sists of a lantern, pan, and re- 

 flector : 



A represents an ordinary lantern, 

 constructed in any of the known and 

 usual ways. Around the base of this 

 lantern is attached a shallow basin, 

 B, of any suitable dimensions say, 

 for instance, thirteen inches in diam- 

 eter and two inches deep. Immedi- 

 ately below this basin, and attached 

 to it, is a tube, C, of proper dimen- 

 sions, to facilitate the using of the 

 lantern in the field, by being placed 

 on the post or stake. At the top of 

 the lantern is a horizontal screen, D, 

 of tin, forming a reflector to economize 

 the light by throwing it outward. 

 Another and important object and effect of this reflector is to precipitate the insects 

 into the pan below. Many of the insects will flutter, and ascend the sides of the 

 lamp with considerable rapidity, thus coming in contact with the reflector and 

 causing them to fall into the pan, which contains water, sirup, or some other suit- 

 able liquid for destroying them. 



The advantage claimed for this invention is that the light is equally 

 diffused in all directions, thus alluring more insects than it would were 

 the light partially obstructed. 



Fig. 66 is a representation of the invention of Mr. James G. G. 

 Garrett, of Port Gibson, Miss., No. 133,023, November 12,1872. In his 

 letters patent Mr. Garrett says : 



This invention relates to that class of devices for destroying or catching nocturnal 

 insects which consist essentially of a dish or pan containing molasses or other sticky 

 substance and a lamp, the light of which decoys the insects into the pan. All such
