Dr. J. C. Neal discusses’ a number of injurious insects that have 
appeared in Oklahoma. He includes Preris rape, Plusia brassice, 
Heliothis armigera, Diabrotica vittata, Lytta cinerea, Oncideres cingu- 
lata, and Blissus leucopterus 
The recent biennial report of Prof. S. A. Forbes as Director of the 
Ilinois State Laboratory of Natural History, shows that entomologi- 
cal studies are being vigorously prosecuted in that favored State. 
Fully 20,000 specimens have been added to the pinned collections, and 
2700 bottles and vials to the biological series. We are glad to note 
the announcement to two important papers soon to appear in the Bul- 
letin of the laboratory, the first by Mr. John Marten, containing 
descriptions of new species of Illinois gall gnats, and the second by 
Mr. C. A. Hart, a descriptive list of the aculeate Hymenoptera of 
Illinois. 
PSYCHOLOGY. 
Notes on Habits of Certain European Birds.—M. Ch. von 
Kempen has recently published some observations on birds from which. 
the following extract is quoted to show the voracity of the ordinary 
sparrow-hawk (Aceipiter nisus): 
“ For several years I lived in the country, and was accustomed to 
write during the summer near an open window. The apartment had 
from one side a view of the garden ; from the other one looked out 
over the fields. Suddenly I saw a sparrow-hawk dart through the 
room; he flew with such violence that he broke the glass of the win- 
dow, against which he dashed in his impetuous flight. I soon had an 
explanation of the circumstance. A linnet (Sylvia hortensis) perched 
near me was eyidently the attraction. The warbler had flown into the 
room to escape the hawk, which in headlong pursuit, had gone through 
the room like an arrow from a bow. 
“In February, 1889, I had in my town garden a certain number of 
lapwings ( Vanellus cristatus); each evening, when I would go to shut 
them up in a cage, I would find one less than I had counted in the 
morning ; I attributed this loss to a cat belonging in the neighborhood. 
The third day on missing another of my pets, I resolved to discover 
the thief, and concealed myself for that purpose. In the morning I 
saw a sparrow-hawk coming straight to my garden from the old tower
