BOUSEHOLD AND STOHEnOTTSE PESTS. 345 



in part for their rapid increase in this locality. I have before 

 me now (January 2d, 1883,) a sample of Tuscany wheat (crop 

 of 18,S2) received in this city about the 15th of November last, 

 m a close-fitting paper box and apparently in i)erfect order. 

 It was kept in an office where the temperature is generally 

 above sixty-five degrees, for about three weeks, or until alxnit 

 the 10th of December. On examination, it appears as if every 

 kernel produced a weevil. I have kept them since that time 

 and they still appear healthy. It is not Iw examining the sur- 

 face of the grain heaps that the presence of this pest can be 

 detected, but by examining at a depth of say four or more 

 inches below the surface. By putting some of the grain in a ' 

 vessel and then covering it with water, those kernels infested, 

 or which the larva or perfect insect have eaten out, will float. ' 

 ►Since writing the above, I have made some investigations, 

 which are not yet complete, (August 27th, 1883), but I have' 

 reason to think that the grain weevil (C. granaria) infests the 

 wheat when growing in the field, and that the germ or egg is 

 laid in the wheat (or, at least, in some of it) before it reaches 

 the granary. 



_ On the 14th of August, 1883, I found the male insects of the 

 nee weevil (Calanclra [Sitophilus] oryzce) in considerable num- 

 bers among the wheat weevils ; and also found them pairing 

 with the females of the latter. 



Description of Rice ^A^eevil : Male not so large as wheat 

 weevil, and has two red or yellowish-red spots on each wing- 

 cover. 



Remedies.-No. 72, No. 75 and No. 76, and careful selection 

 of seed ; general remedy for weevil, No. 119.
