of the first brood averaged 76. The highest number of eggs laid by a 

 single female was 128. This is a larger number of eggs than we ever 

 dissected from any female's body. The average number of eggs laid 

 was 64. The number of eggs laid in a single needle varies from 1 to 20, 

 the average number being 6. The eggs are usually laid in needles of 

 the previous year's growth, if any are present. The majority of the 

 eggs for the first brood in Connecticut hatch during the first half of 

 May, while those for the second brood hatch early in August, but the 

 broods overlap. It sometimes happens that some of the first brood of 

 females are so late in emerging that the eggs which they laj^ do not 

 produce larvae until after some of the second brood eggs have hatched. 



President C. Gordon Hewitt: Does anj^ one wish to discuss this 

 paper? . , 



Mr. R. L. Webster: I am much interested to know that Mr. 

 Zappe reared sawflies from unfertilized eggs. In work with Harpipho- 

 rus maculatus, I had a similar expenence, although I secured one female 

 from an unfertilized egg. I am wonde ing what the experience has 

 been of other men who have worked with sawflies. 



Mr. Max P. Zappe: By next spring I may know more about this 

 as I now have several cocoons reared from eggs of virgin females from 

 which adults have not yet eme-ged. 



President C. Gordon Hewitt: In my own study with the larch 

 sawfly, Nematus erichsonii, the female was quite common in that 

 species but both sexes were reared from unfertilized eggs. 



If there is no fm'ther discussion, the next paper will be given by Mr. 

 Manter. 



NOTES ON THE BEAN WEEVIL (ACANTHOSCELIDES 

 [BRUCHUS] OBTECTUS SAY) 



By J. A. Manter, Storrs, Conn. 



The common bean weevil is considered by many entomologists as 

 the most destructive pest attacking beans. It is especially injurious 

 in the Southern States. This beetle was first described by Thomas 

 Say in 1831 but did not attract notice as an economic species until 

 1860 when infested beans were sent to Doctor Fitch from Providence, 

 R. I. During the next ten years it was reported from several widely 

 separated states and now is common throughout the country. 



At first the bean weevil was credited with habits similar to those of 

 the pea weevil {Laria pisorum L.) and the same control measures 

 were recommended for each. When the life-history was studied it
