POISON, 



Directions How to Catch Moths, etc. — The contents of the 

 bottles are prepared by dissolving Cyanide of Potassium in water, and 

 pouring into the bottle to the depth of half an inch ; then drop in Plaster 

 Paris until it thickens, and let it stand until hardened, keeping it corked. 

 To catch moths with it, the best way is to take sugar from a molasses 

 hogshead and mix with water, making it thick ; spread this mixture on 

 old posts, or trunks of trees, fences, &c, for two or three days. When the 

 moths begin to scent the sugar, provide yourself with a small lantern 

 giving light only on one side ; visit each post and tree, and you will find 

 moths by letting the light shine on the sweetened places. Then hold the 

 bottle under one of them, and it will dart or fall into it ; cork immediately 

 or it will fly out. Then put the bottle in your pocket, and use another 

 bottle to catch the next one, and by that time the first bottle will be ready 

 for use again. You can thus visit each post, and when you reach the last 

 one it is better to put the moths into a box, so that the new ones will not 

 spoil them by flying among them. Some persons dip old rags into the 

 syrup and hang them up to attract the moths. 



Dear Sir, — 



From a friend in the neighborhood of Salt Lake, Utah Territory, I 

 received a small lot of Lepidoptera, and as collectors would no doubt be 

 pleased to learn something of the fauna of that locality, I will give you a 

 list of the insects received, viz : 



Papilio daunas Boisd, Gnophaela vermiculata, 



Pieris protodice Boisd. & Lee, Deilephila lineata, 



Anthocaris ausonides Boisd., Platysamia gloverii Strecker, 



Colias eurytheme Boisd., Arctia americana, 



Vanessa antiopa Linn., Catocala faustina ? Strecker, 



Pyrameis caryae Hiibn., Erebus odora, 



Lycaena anna, 



Chrysophanus helloides Boisd. 



Of Platysamia gloverii I received two examples, both males, and as 

 there were none of P. cecropia among the lot, I would take it to be a 

 proof that gloverii is not a form of that species. Besides the differences
