added years later. At this time the writer has some lichens for determination 

 that were collected in Michigan over fifty years ago. My own record book is 

 bound in half morocco, contains 200 pages with thirty-two lines on a page, with 

 a single vertical red line near the left edge of each page. In the space thus 

 marked off are the serial numbers. On the top line is one number, then on the 

 seventh Une below is the next, and so on, leaving six lines under each number 

 for data. Thus, on each page are five numbers, and 1,000 in the whole book. 

 A sufficient amount of material (fruiting material, preferably), to represent the 

 species, is placed in a pocket of tough white paper, made by bringing the bot- 

 tom of the sheet up to within about one-half inch of the top, and creasing ; the 

 top half-inch is folded down and creased, and then about one-half inch of 

 either end is folded back and creased. The shape of the flat sheet will determine 

 the shape of the pocket. Several sizes of pockets should be on hand. The 

 writer has found it most convenient to have labels printed for each locality 

 where much collecting is done, as they can be had for 15 cents per hundred of 

 the Cambridge Botanical Supply Company, Cambridge, Mass. The labels 

 should be pasted onto the half-inch turned down from the top in making the 

 pocket. The pockets should be fastened to herbarium sheets of standard or 

 half-standard size by a dab of liquid glue in the middle of the back of each. 

 They should be fastened around the edge as well as the middle of the mounting 

 sheet, so that when the sheets are placed in a pile it will be of uniform thick- 

 ness. 



A helpful way to learn how to do this is by seeing same prepared specimens. 

 In order to afford this opportunity, and to draw attention to this group of plants, 

 with a view to ultimately finding out what we have in this state, the author has 

 offered to send a set of prepared lichens to high schools of the state that will 

 properly care for them and pay postage — ^about 24 cents — on same. He will 

 undertake to determine such material as may be submitted. If the specimens 

 are to be returned, postage will be expected of the sender. E. E. Bogue.

Directions for Collecting, Preparing, and Preserving Specimens 

 of Orthoptera for the Cabinet/ 



The writer has been appealed to so frequently for aid in determining collections 

 of Orthoptera for various institutions and individuals in different parts of the coun- 

 try, that it has been decided to make an attempt at building up a typical refer- 

 ence collection of these insects here at the University of Nebraska. In order 

 that we may obtain this material in as excellent a condition as possible, and also 

 to encourage and aid others in their study of the group, the present brief paper 

 has been prepared. 



Perhaps no other group among insects has been so much neglected by their 

 devotees as have those belonging to the order Orthoptera. The chief reason 



' Special Bulletin No. 2 from the Department of Entomology in the University of 

 Nebraska.
