THE INSECTS OE NEW JERSEY. 
Family CAEANDRIDiE. 
397 
Stoutly built, very rigid weevils, with deeply striate wing-covers and 
characteristically marked thoracic sculpture. The beak is usually mod¬ 
erate in length and stout. The family contains the “corn bill-bugs,” the 
“grain weevils” and “rice weevil,” and a considerable proportion is 
therefore of economic importance. In the principal genus “Sphenophor- 
us,” Mr. P. H. Chittenden has been good enough to assist in the arrange¬ 
ment of species. All the members of that genus breed in reeds and 
grasses, and preferably such as have large or bulbous roots.

eaten by the adults when they mature in late June or early July.
