half of its food in fragments of corn and other grains and seeds

 about half the food for each month, except in May, when

they rise to three-fourths, and in July, when they drop to 

 one-fourth. The excess in May occurs at the time of the 

 greatest number and activity of the beetles, and the diminu- 

 tion in July coincides with the period of the greatest abun- 

 dance of the small fruits. One-half the hisects eaten are 

 beetles, wliich stand at one-fourth of tlie food in April and 

 June, rise to one-half in May, and fall to about one-eighth in 

 July and August. Half the beetles of the year are Scara- 

 bseidiB, chiefly June-beetles and Euryoma, all taken previous 

 to July. Nearly oiic-rourth of llic beetles are Carabid^, 

 which remain at al)()ut fivt? per cent, of the food, except in 

 May, when they rise to ten per cent. Although the ratios
