Upon taking up some of these stems I was much in-terested in finding an attack quite unknown to me. The base ofthe stem had been entirely eaten out by a footless, yellowish-white grub, one-fourth of an inch in length, with a chest nut-brown head and the posterior end of the body becoming rapidlysmaller at the last two rings. On taking the grub from the oatstem it progressed quickly across a table, working itself along 266 INSECT ENEMIES OF SMALL GRAINS. by moving the rings of its body like a dipterous larva and atthe same time making use of its slightly extensile tail to pushitself along. Mr. Fletcher does not consider the insect to be one that willever become a destructive grain pest, as it seems to prefer-towork upon the grass Panicum criis-galli THE GEAIN WEEVILS. {Cdlcmdra granaria Linn, and others.) This is the true grain weevil,concerning which so much hasbeen written, both in this and Eu-ropean countries. It is a blackishsnout-beetle very similar in formto the difPerent species of bill-bugs described or mentioned inmy paper on Corn Insects, butmuch smaller—being about one-fifth of an inch in length. It is wellillustrated in the accom[)anyingillustration (Fig. 68) at e, en-larged and natural size. In thiscountry the insect is less common than in Europe, and occurschiefly in old granaries and corn cril)S, where it feeds upon thestored grain. It attacks both corn and wheat, as well as some ofthe other grains. The mature beetles, as well as the larvae, feedupon the grain. As a remedy, the us
