AuLT. 27tli. Tlic C"lub met juiisuanl to afljournnienl, at 7I'. .M.' 

 Prof. Lintner in the chair, 12 persons present. The minutes of the 

 previous meeting were read and adopted. Continuing the discussion of 

 the previous meeting. Prof J. A. Cook slated that the grass-hop[)ers {(\ 

 /dfw«/--/-«<^r«///) liad been very destructive m Michigan. Man\' fields ol 

 oats had been nearly destroyed. Tlie heads liad not been eaten off as 

 stated by Prof. Osborn to be the 'case in Iowa, but the separate berries 

 or grains had been cut off, antl often covered the ground. Meadows 

 and pastures had also suffered greatly. These insects seemed worst 

 where the season had been characterized by a drouth. Several years 

 ago a similar devastation occured in this State, but was serious only for 

 a single year. The Army Worm, Z. unipuncta Haw., had been seriouslv 

 destructive in the south-western portion of the State, where it also did 

 serious damage three years ago. Neither of these visitations could be ac- 

 counted for on the explanation given years ago by Fitch, as the wet and 

 dry years of the first raid were the reverse of Fitch's rule, while this 

 year and last had both been very dry in this region. The "Rlack Arm\- 

 Worm"' Agrotis fenniia was very abundant and destructive last year ab(,)ul 

 Bay City and up the Saginaw River as far as Saginaw City. The num- 

 bers were fairly prodigious; bushels could be gathered in a few minutes. 

 Hundreds could be crushed by a single fo(n-fall. Gardens and meadows 

 were totally stripped of every green thing. I'his year the region devastat- 

 ed last year had wholly escaped damage, though a similar attack had 

 been suffered farther up the Huron Shore. Other cut-worms had been 

 unusually abundant and destructive in the State the past vear. Anihono- 

 mils musiulus Say, had done much damage to strawberries in the North 

 ern Peninsula last year and the year before. This year it had done little 

 harm. Byiiirus imkolor Say, for the first time had done much damage 

 to raspberries in Michigan this season. These msects were much more 

 .gray than the description of Say, or specimens in the College Cabinet 

 previously collected would indicate. They are easily destro\ed by the use 

 of Paris Green. Prof Cook also referred to a species of Noctuid iMolh, the 

 larva of which was doing much damage by eating the wheat in the bin. 

 This insect had cione much damage both last year and this. He had 

 been unable to rear the insect. 



Prof. Osborn says that the habits of the grass-hoppers in Iowa v/erc 

 as Prof Cook describes them. He said they ate off the heads of the 

 oats; it would have been more correct to say that usually they ate the 

 separate kernels.
