Directions for Sendinc. Living Aphids. 



It is desirable, in sendins; aphids for determination, that 

 li\ing indi\idiials be submitted wiicn possible. We ha\e found 

 the following method to be the most salisfactor\- of se\eral tried: 



Place a portion of the plant bearing the aphids in a glass 

 \ iai and with it a strip of filter paper, the size depending on tiie 

 size of \ial and qiiantit\- of foliage placed within it. The \ial is 

 then tightly stoppered with a cork and j)laced in a mailing tube 

 or substantial bo.x for mailing. Always ha\e the stem of the plant 

 and the end of the filter paper sufficiently long so that; the\- will 

 be held by the cork; otherwise the loose foliage and twigs will 

 shake about and ma\' crush the aphids. By this method we 

 ha\e shipped li\ing specimens 1,700 miles and had them reach 

 their destination in excellent shape. Tin salve boxes also make 

 excellent shipping boxes for li\ing aphids. Shipments of this nature 

 should always be accompanied by full data, such as name of food 

 lilant, localitx-, date, part of plant affected, and collector.
