DIRECTIONS FOR COLLECTING, PRESERVING, AND TRANSPORT- 

 ING TORTRICIDS AND OTHER SMALL MOTHS. 



OOLLECTma APPABATUS. 



1. A common insect-net of swiss muslin on a stout wire hoop about 

 1 foot in diameter, secured to a light pole 5 or 6 feet long and about 1 

 inch in diameter at the larger end. The net should be from 20 to 24 

 inches deep, and made with a rounded bottom, so that there shall be no 

 close corners into which the insects can crawl and rub off the scales 

 from their wings. 



2. A supply of pasteboard pill-boxes 1 inch in diameter and five- 

 eighths of an inch deep. Each one should have a pin-hole in the middle 

 of the cover. These boxes should be lined on the inside with unglazed 

 paper, so that the living insects may hold on by their feet, and not be 

 rolled about and denuded of their scaly covering. 



PRESEKVING APPARATUS. 



1. Cork-lined storing boxes of well-seasoned wood for preserving the 

 insects after they are captured and pinned. These may be of any con- 

 venient size, but the cork must be firmly secured, and the insects must 

 be firmly pinned to the cork, so that they can by no possible chance be- 

 come loosened or detached. 



2. Insect pins of several sizes, adapted to the different sizes of the 

 insects captured. The black or japanned pins are far preferable, since 

 they do not corrode, and thus destroy the specimens. Small silver or 

 gilt pins are desirable for the smallest species. 



3. A bottle of chloroform and a camel's hair brush to use in killing 

 the insects. 



4. A piece of dry corn-pith, or some similar soft material, to rest the 

 insect upon when pinning it. 



5. A pair of Jine brass forceps to handle the insects with, for they 

 should never be touched with the fingers.
