 Flies.) 



5. Ephemeroptera , (Mayflies.) 



6. Odonata, (Dragon Flies). 



Order VII {Trichoptera) includes the Caddis Flies

 Butterflies and Moths specially dealt with in the pre-

Order IX (Diptera) is made up of Fleas, Flies, Midges, 

 and Mosquitoes, and is an Order capable of almost

 species is concerned, owing to the fewness of the students 

 who concentrate attention upon this highly important 

 branch of Entomology, and 



Order X [Hymenoptera) has, as its representatives. Ants, 

 Bees, Wasps, Saw Flies, Ichneumons, and Gall-Wasps.

 again are ground-surface dwellers, and others pursue
