slender legs, capable only of slow motion. They live upon 

 the tender parts of plants. 



4th. Jumpers, as crickets, locusts and grasshoppers, whose 

 hind legs are longer than the others, and adapted to quick 

 and long leaping. 



This is the most prolific, as well as the most destructive, 

 of the Orthoptera. Some of the crickets prey upon other 

 insects, but the principal food of the jumpers consists of 

 the green parts of plants. 



4. "H EM IPTERA ($2^, locusts,plant-lice, etc.} Insects with 

 a homey beak for suction, four wings, whereof the upper- 

 most are generally thick at the base, with thinner extrem- 

 ities, which are flat, and cross each other on the top of the 

 back, or are of uniform thickness throughout, and slope 

 at the sides like a roof. Transformation partial. Larvae 

 and pupae nearly like the adult insect, but wanting wings." 



Some of the field and house bugs of this order emit very 

 offensive odors, when disturbed. Some live on the juices 

 of animals, and destroy vast numbers of noxious insects. 

 Others are useful in supplying dye-stuffs of great value in 

 the arts. 



Others, embracing plant-bugs, plant-lice, bark -lice, mealy 

 bugs, etc., that suck the juices of plants, are very injuri- 

 ous, and difficult to destroy. 



5. "NEUROPTERA (dragon-flies, lace-winged flies, May. 

 flies, ant-lions, day-flies, white ants etc.) Insects with jaws, 

 four netted wings, of which the hinder ones are the largest, 

 and no sting or piercer. Transformation complete or par- 

 tial. Larvae or pupae various." 



Many of this order prey upon other insects both in their 

 larvae and adult states. Dragon- flies are especially useful in 

 destroying gnats and mosquitoes. The lace-winged flies, 

 in the larva state, destroy great numbers of plant-lice. 



6. "LEPIDOPTERA scale- winged, (butter flies and moths.) 

 Mouth with a spiral sucking tube, wings four, covered with 

 brawny scales. Transformation complete. The larvae
