 Proceedings of the Entomological Club of the AAA. S 



(Continued from page 123 ante. ) 



Aug. 27th. The Club met pursuant to adjournment, at 7 P.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 stated that the grass-hoppers (C 

 femur -rztirum) had been very destructive in Michigan. Many fields ol 

 oats had been nearly destroyed. The heads had 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, and 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, L. unipuncta Haw., had been seriously 

 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 "Black Army 

 Worm" Agrotis fennica was very abundant and destructive last year about 

 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 foot-fall. Cardens and meadows 

 were totally stripped of every green thing. This 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 year. Anthono- 

 mus musculus Say, had done much damage to strawberries in the North- 

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

 harm. Byturus unicolor Say, for the first time had done much damage 

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

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

 previously collected would indicate. They are easily destroyed by die use 

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

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

 This insect had done 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 were 

 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.
