It was feared that during 1896 there would be a further spread of theweevil 5 but for some reason, probably on account of the severe mid-summer drought, there was not only no spread beyond the limits of1895, but on the contrary a shrinkage of the territory infested. Themain spread in 1895 took place in the autumn, and at the outer bound-aries, as at San Antonio and Wharton, the weevil was killed by thewinter frosts. In 1896 the drought prevented the make?? of the topcrop at many points and there was little food for the autumnal genera-tions of the weevil, and therefore a lesser spread from the localities ofsuccessful hibernation. 10227—No. 47 2. Fig. ?Thecotton-boU weevil (Anthonomut grandii): a, adult beetle;6, pupa; c, larva—enlarged (from Insect Life). 18 NATURAL HISTORY AND HABITS. The insect passes the winter in the weevil state. It can be found onthe cotton plant until late in December, and, in fact, as long as anyportion of the plant is green. It is found most abundantly in the earlywinter hidden between the involucre and the boll, and later it frequentlyworks its way down into the dry and open bolls. All tbe specimensfound by Mr. Schwarz in such situations in the late spring of 1895 weredead: but Mr. Townsend found a few living in March. The dry bollis probably not a frequently successful hibernating place.
