ture stages continue to develop after frost. At College Station we 

 were unable to ascertain that any of these come to inaturity or survive 

 the Avinter under normal conditions, and we believe this to be the case 

 generally in central and nortliern Texas. In southern Texas, especially 

 the more southwestern part, the conditions are dift'erent, however. 

 In February and March, 1903. we received a large number of bolls 

 from Devine, Tex., containing larva% pupa\ and adult weevils, mosth^ 

 newly transformed. Some of these were found within the seeds, but 

 there is comparatively no danger that they woidd ever be dissemi- 

 nated in the seed, since practically none of the cotton in Avhich they 

 entered the seeds Avould ever l)e picked and ginned. Many of these 

 weevils were alive early in April, and in southern Texas would have 

 emerged before that time. Out of '200 bolls picked at random '20 per 

 cent contained living or dead weevils in some stage, and of these 55 

 per cent were alive. Mr. W. P. Allgood, Avho sent the bolls, at the 

 writer's request, made careful counts, which sliowed that in the fields 

 from which the l)olls were secured there Avere about 10,500 Aveevils per 

 acre. If but 20 per cent of these had survived and had emerged in 

 the spring, there would haA'e been 2,100 per acre, and this is approx- 

 imately the number which surviA'ed during the last Avinter (V.)0?>-4) 

 in Lavaca County, Avhen the number surviving hibernation Avas 

 unprecedented. Furthermore, the rainfall at De\ane Avas nearly 

 double the normal during this Avinter and Aveather conditions were 

 exceedingly unfavorable for the hibernation of AvecA'ils had they been 

 hibernating in the fields in the usual situations; but inside the bolls 

 they Avere Avell protected from dampness and the temperature Avas 

 neA^er so Ioav as to injure them. The importance of the absolute 

 destruction of the stalks in southern Texas, CA'en if deferred until mid- 

 winter, is therefore apparent, although in the rest of the State it is 

 valueless after killing frost. 



Kegardiug the places of hibernation we have been able to secure 

 but little direct evidence. Just after hibernation commenced Mr. 

 Conradi was able to find four A\eevils under leaA^es in a cotton field 

 and under bark of a log adjoining it, but later in the winter absolutely 

 none Avere found. Tliough many days have been spent in the most 

 careful examination of the places Avhere the weevils are supposed to 

 hibernate, Ave haA'e found but one individual in midAvinter. As this 

 has been our experience in hunting for other hibernating insects, how- 

 ever, Ave are not surprised. There is, nevertheless, abundant indirect 

 evidence that most of the Aveevils hibernate in the cotton fields and in 

 adjoining Avoodlands. Infestation usually commences in the spring 

 along a Avoodland or hedge roAV, and is Avorse in a field Avhich has 

 been in cotton than one in corn. It is Avorse Avhere sorghum adjoins 

 cotton, as the sorghum stubble or stacks seem to form a safe shelter 

 for the Aveevils. Furthermore, Ave are compelled to believe that the
