larvae or uruhs that woukl doiitnless live throuuh the winter. A delay till 

 the second season appears to be quite common in this species, and is one of 

 nature's safej^^^iiards ai^ainst extermination should there be an entire failure 

 of the crop in an)- out; year, as hap|jens occasional!)-. This smaller species 

 is known to breed in chintpiapin nuts and acorns, as well as chestnuts while 

 the lart^rer forn-i has been obtained onl)- from the latter. There is a|)|»a- 

 rently no record of the laru;er sjiecies remainiiiu- in the pui^a sta^^e till the 

 second year, althouL,di it is probable that such occurs. ( )nl\- one ])arasite, 

 U r o s i t;- a 1 j) h u s a r m a t u s Ashm. has been bred from this chestnut 

 weevil. 



Remedial measures. Iherc is no jjractical method of prexcntiiij^ o\-i- 

 ]josition, unless it be 1)\- jarriiij^- which \\-ould jjrobabl)- pro\'e too e.\pensi\e 

 in most cases. The inf(;stetl nuts shouKl be destroxed each \-ear before- the 

 insects forsake ihem ami entf-r the ground. \\ Ornn chestnuts ma)- be 

 easil)' recos^-ni/ed b\ pourint;- the nuts into a \'essel of water, and the liuluci- 

 ones will rise to the surface after a little stirring. I he soun^l oiies should 

 be tlried, and it would be safer to thoroughK- treat them with carlion 

 bisulhd, using at least one ])ound for each looo cubic feet of space and 

 exposing the nuts to the fumes for about 24 hours.
