Collecting, Mounting, and Preserving Galls 17 



which to search for galls growing on bushes and trees. The 

 continual movement of the foliage makes detection very difficult 

 and wearies the eyes. 



An attempt has been made in each synoptical table to direct 

 the collector to the most likely places in which the galls are to 

 be found, and for further information in this section reference 

 thereto must be made. 



Mounting galls and the imagines which emerge from them 

 may be accomplished in various ways. The particular method 

 of arrangement in the cabinet or wall-case may be left with the 

 galiist to adopt which ever is most suitable to the conveniences 

 at command. One thing is most essential : the galls should be 

 allowed to dry thoroughly before placing them in their final 

 positions. 



The following suggestions may prove useful to the galiist 

 who has not decided upon any definite plan of arrangement. 

 A small label should be affixed to each specimen, or cluster 

 of specimens, bearing (a) name of plant, (d) name of creature 

 producing the gall, (c) locality where found, (d) date of find, 

 (e) a number corresponding with the same in note-book or 

 catalogue. Imagines of average size may be fixed on a small 

 piece of white card, or put in a small glass phial, which has 

 upon it a number corresponding with that on the label and 

 date of emergence. 



Parasites and inquilines should be put in a separate phial 

 labelled accordingly, and placed by the side of that containing 

 the imagines. 



Very small imagines which require a lense or microscope for 

 their examination may be mounted in the following manner. 

 Cut a piece of card, of about double the thickness of a post- 

 card, the same size as a microscope glass slip — viz: 75 mm. x 

 25 mm. — and with a steel punch of 12 mm. diameter make a 

 hole in the card. A slight burr will be caused on the under 

 surface of the card, which should be removed with a sharp knife 

 or rubbed down with the thumb-nail. This surface of the card 

 must then be seccotined, and one of the glass slips placed upon 

 it and allowed to dry. When dry, affix a name-label on the 

 card, fill in particulars such as have already been suggested, and 

 then place the creatures in the cavity of the card. Seccotine 

 the outer margins of the card, and place the other slip on, and
