INJURIOUS INSECTS OF 1904.

-Skull of Hare Showing 

 Incisors. 



Extra 



incisor teeth in the upper jaw just behind the large pair; our illus- 

 tration shows this peculiarity. 



Turning once more to the squir- 

 rel family, Scinrida:, we find there- 

 in two or three forms which gave 

 us the name of "Gopher State," 

 but which are squirrel-like in their 

 structure. These all belong to one 

 genus, Spcrmophilus, which means 

 seed loving, and, sure enough, we 

 find that they are fond of almost all kinds of seeds — wheat, oats, 

 rye, barley, corn, pigeon grass, millet, sunflower, pig weed, rag- 

 weed, black locust, solanum, strawberries, and a host of others. 

 They also eat green leaves, roots of trees and plants, and grasshop- 

 pers, crickets, beetles, ants, cutworms, lizards, mice and other 

 forms of animal matter. The members of this genus have pouches 

 but, unlike those of pouched gophers, they are inside the cheeks 

 and not distinct from the cavity of the mouth. Their bodies are 

 slender. They eat like other squirrels, sitting erect and bringing 

 their food to their mouths with their front feet.
