222 MOSQUITOES 



be ciiniocT safely or can be sent in the mails. Several of 

 the pill boxes may be placed inside a tight tin or wooden 

 box and mailed with perfect security. 



A collection of mosquitoes should, however, not be kept 

 in this way, provided it is intended as a study collection. 

 The method which I have adopted and which is the 

 one customarily used for small insects that are not too 

 small for hand-lens work, is the triang-ular-tag- method. 

 Take a sheet of stifi' paper or very thin cardboard and cut 

 a strip, say, five-sixteenths or three-eig'hths of an inch 

 wide. Then from this strip, by slightly oblique cuts, 

 cut a series of triangles that will be pointed at the tip 

 and a little less than an eighth of an inch wide at the 

 base. Through the base of the tag maj^ be run an insect 

 pin and to the tip the mosquito should be glued, white or 

 yellow shellac being the best medium for the gluing. The 

 mosquito should be glued on its side, just behind one 

 wing, so that its back is away from the pin. This enables 

 one readily, by holding the point of the pin in his hand, 

 to examine with a lens all legs, antennn: , jialpi, one side, 

 and the back. The tag should be pushed up on the ]un 

 until it is from two-thirds to three-quarters of the length 

 of the pin away from the point. To the lower part of the 

 pin should be attached a small label, giving date, exact 

 locality, and name of the collector, and below this may be 

 pinned another small label, bearing the name of the 

 insect. 



Those who for some reason do not like the jiapor tri- 

 angle method of mounting use very minute pins made by 

 Miiller in Vienna and known as " minuten insektcn nii-
