may he rpgardcd as a token of fine weather. Wlien any 

 number of tliis specieN are on the wing early in the niominj?, 

 it rarely happens but a fine day ensues. 



It wUI next be necessary to describe the instruments with 

 which the Aurelianist should be provided, as well as the 

 best method of employing them. First, he must be prepared 

 with a Stbonq Knife, or what is styled by Mr. SamoucUe a 

 Digger, which consists of an iron five mches long, and 

 rather more than one-third of an inch in diameter, forming 

 a curve towards the extremity, and terminating in a lozenge- 

 ."haped point, sti'ongly fixed in a wooden handle. The use 

 of this is to explore the interior of timber trees, and to grub 

 up the turf under them, as well as to examine the earth for 

 the impcB. But what is yet better for this puipose is a potatoe 

 fork. Secondly, a Stick, to beat the branches of trees, with 

 a screw fitted at one end, with a brass cap to keep out the 

 dirt. For catching the Butterfly in its flight, a Bag-net is 

 essentially necessary. This must be formed of two semicir- 

 cular pieces of iron or bra-ss wire hooked together at one 

 end, and at the other made to lap over the corresponding 

 piece, and pierced so as to receive the screw at one end of 

 the stick. When not employed, the hoop may be doubled 

 up and concealed under the vest. To this must be affixed a 

 muslin bag, two feet in length. This sort of net fixed to a 

 pole twenty or thirty feet long is, Mr. Huworth says, the 

 best net for cajrturing Apatara Iris, the I'nrplo Emperor 

 Butterfly. An adroit collector by giving it a certain twist 

 completely closes tlie mouth so as to prevent the escape of 

 his captives. 



The Klv-net is also much u.sed. This shonid be made of 

 white gauze or coarse muslin ; and the rods of tough wood, 

 about five feet in length, half an inch in diameter, and 

 ijraduiiUy tapering to the end. Each of these rods should
