Scarahaeidae of Nebraska 131 



Specimens examined: 124, from Maskell, Omaha, 

 Ashland, Nebraska City, Lincoln, West Point, Norfolk, 

 Neligh, Fairmont, Bradshaw, Minden, Ravenna, McCook, 

 and Mitchell. Gibbosus is an abundant widely distributed 

 and rather variable species. It is commonly called the 

 Carrot Beetle, because it frequently injures the roots of that 

 plant. It is also destructive to beets, potatoes, parsnips 

 and corn. The larvae are recorded as occuring in num- 

 bers around well rotted manure piles.
