Entomological forceps, with curved ends for holding pins. [See 

 p. 53.) 



A supply of No. 20 and No. 16 entomological pins. (See p. 53.)

Importance of Sending Specimens for Determination and 

 Description in the Best Possible Condition. 



It should be borne in mind that, for the purpose of the scientific 

 determination of species, mosquitoes cannot be collected vnth too great 

 care. As important specific characters are furnished by the scales, 

 vnngs, and legs, it is of the utmost consequence that the scales should 

 not be rubbed off, or the wings and legs injured. Unless attention is 

 jxiid to this point the specimens vnll prohahly he quite v^orthless for 

 determination or description.
