few individuals of most species and of some 

 families were present for meaningful interpre- 

 tation. Thus data for insects are presented for 

 families, and sparsely represented families 

 of an order are sometimes combined in tables 

 and shown under the order. Data for other 

 invertebrates are usually presented by phylum 

 and order. Individual insects were identified 

 to genus and species when possible. The 

 following list (after the order of Pennak, 1953) 

 gives the most precise identification made for 

 various organisms,
