vented, and the wings are kept from being broken 01 

 the scales from being rubbed from the body and wings. 

 After this is done, the poison-bottle, with the cork out, 

 may be inserted under the net and the butterfly let into it, 

 where he will soon succumb to the poisonous fumes. In 

 taking small specimens out of the net it is not necessary 

 to seize them between the thumb and finger : with the 

 hoop on the ground, the bottom of the net may be raised 

 up, when they will fly upward as far as they can get. 

 Inserting now the open bottle into the net, the specimens 

 are easily secured. 



After the butterflies are captured, what we shall do with 

 them depends upon whether they are to be at once pre- 

 pared for the cabinet, or whether for any reason this 

 cannot be done. Only entomological pins, or those pre- 

 pared specially for this use, should be used in pinning 

 specimens. For butterflies, Nos. 3, 4, 5, and 6 of Klaeger's 

 make are considered the best, suiting the pin to the size 



of the insect. The pin 

 should be inserted into 

 the middle of the thorax, 

 and passed through till 

 at least one-fourth of 

 the pin is above the 

 body, some preferring 

 as much as one-third 

 being left above. This 

 will give room to take 

 hold of the pin in trans- 

 ferring from box to box without injury to the covering 

 of the thorax, and will bring the specimens to the same 

 height in the cabinet. After pinning, the wings should
