The Bulletin. 



An infested plant soon begins to droop and wilt as a result of its 

 attacks. This is an insect which might become very serious, but at 

 this time is of minor importance to the cotton grower. "When an in- 

 fested plant is noticed it should be destroyed, or the borer should be 

 cut out and killed.

The Cotton Stalk Borer (Ataxia crypto). (Order Coleoptera). — 

 This insect affects cotton in much the same manner as the Stalk Borer 

 just discussed, but the adult (parent) insect is a beetle instead of a 

 moth. The larva is a white grub which bores within the stem of the 

 cotton plant, but seems to confine itself mainly to plants which are 

 already injured, and does not, therefore, seem likely to become a 

 serious pest. We have had specimens of injured cotton sent to us 

 from Gaston County in late July (1906), while the adult beetle is 

 represented in our collection by specimens taken in Wake and Samp- 

 son Counties in April. 



"Click-beetle" or "Jack-snapper" (Order Coleoptera). — Of this 

 interesting group of beetles a species known scientifically as Mono- 

 crepidus vespertinus has been quite frequently sent in to us under 

 suspicion of being the Boll-weevil.
