Lake and Pose}- counties, Tnd., scarce; May 30 June 27. Cos- 

 mopolitan and known in the United States from Canada to Ari- 

 zona. (Horn.) Throughout the United States. (Casey.) It is 

 the grain or granary weevil, injurious to stored grain since the 

 earliest times. Being wingless it is a strictly indoor species and 

 very prolific, a single pair being capable of producing 6.000 de- 

 scendents in a year. The time required for completion of a life 

 cycle varies with season and climate, the mid-summer period 

 from egg to adult being about six weeks, so that under favorable 

 conditions, there may be four or five broods in a year, or even 

 six in the Southern States. The annual loss from granary insects, 

 of which this species is one of the most important, is estimated 

 by Chittenden at $20,000,000. Closed bins to keep out the insects, 

 and bisulphide of carbon to destroy them are the usual remedies. 



C. remotepunctata Gyll. is by Casey considered a synonym of granaria, 

 though specimens at hand show that it is uniformly smaller, with striae 

 of elytra deeper, their punctures more distinct.
