gate again. We liave also been not a little astonished jit the great 

 abundance of the beetles reared from beans gathered in the field. 

 From one of the green pods above alluded to, gathered July 15, we 

 had obtained by August 15 no less than 62 individuals, and from a pod 

 that was mature and yellow when gathered we have obtained no less 

 than 91 beetles. The largest number of eggs w4iich we have found in 

 a single pod is 82, and these were thrust at the anterior end through a 

 hole that had been gnawed by some Lepidopterous larva and not made 

 by the parent weevil. 



In size there is also very great variation, some specimens being really 

 smaller than the typical specimens of the true ohsoletus. 



We hope in a forthcoming number to give all our notes on the food 

 habits of the Bruchidse.
