" Hardly any hirntei- would think sei'iousjy of the loss of only one 

 stalk of grass in ten, yet the aggregate for the coimtry at large would 

 be enormous. Not only is the damage to a croj) where nothing short of a 

 serious injury would attract attention, but the damage is tUstributed 

 throughout the growing season. As a general rule, each species is most 

 destructive at a different time from the other species of that locality; 

 hence, species of C7-a)iihus \nv\ upon the grass as a succession of small 

 armies. Cotild the loss caused by these species come at one time in the 

 year their destructive power would be better appreciated. Less than a 

 third of the species may be classed as of economic im))ortance, but these 

 possess a ca])acity to cause almost infinite^ loss if the conditi<Mis are 

 favoi-able." 



Addiliotial I'J.vdmplcs of IiiJKri/. From Ojj'icc Notes. — At Champaign, 

 May 2S, ISSo, Cnnnhus larva> were injuring young corn by gnawing the 

 outer leaves at the surface of the ground, and also by eating out irregular 

 holes in the leaves and the blades themselves. Freciuently the leaves 

 were eaten off and lying on the ground or partly drawn into the mouth 

 of the web. Occasionally a i)lant was gnawetl com])letely through at 

 the surface of the ground, as by a cutworm. The injury here was suffi- 

 cient to cause a partial i-eplanling of \\)v field. This land had been in 

 |)asture for fifteen years, and no damage to the grass had been noticed. 

 It was jilowed about the Sth or 9th of May. and planting was finished 

 May 15. 



At Milan, in Rock Island county, August 13. 1885, farmers reported 

 the i^resence of a worm which made a web at the roots of the corn and 

 ate the leaves while young, after which it worked about the roots, cutting 

 them off just below the surface of the ground. Seven acres of corn 

 on sod were almost completely destroyed, only a hill here and there 

 being left. These larva- k^d mostly in the evening and just after a 

 shower. They had been seen traveling from one hill of corn to another. 



At Mt. Pulaski, Logan county, Illinois, according to observations 

 and statements made .luiu^ 1(1, 1SS5, larva' of Cntmhtts zcfUus (= luteo- 

 IcJlus) had so far injured a small field of eight acres of corn that it had 

 been replanted about the last day of .May. On the 16th of June the 

 worms were still somewhat acti\-e, and corn plants were f'retiuently 

 seen which had been more or less injured by it. .Many of the wel)s were 

 vacant, however, the larva' evidently having gone largely into the earth
