LISTING THE MATERIAL EXAMINED 



The final criterion for the identification of larvae must be through 

 their adults. Consequently, larvae that are not definitely associated 

 with available reared adults are of only secondary importance in a 

 taxonomic study. In listing such material the information given for 

 each species has been limited to the following: The total number of 

 larvae examined; the general localities represented, such as States, 

 provinces, or countries; and the institutions in which the specimens
