iEGERIME. 
By Mr. John Marten. 
This family contains the slender-bodied clear-winged moths 
known as iEgerians. The larvae, although true caterpillars, have a 
somewhat grub-like appearance; usually dull white, more or less 
tinged or varied with pale brown or pale dull yellow. The body is 
smooth or slightly downy, without spines or horn on the next to 
the last segment. They have sixteen feet, the abdominal pro-legs 
being usnally very short and almost obsolete in some species (as 
AE. curcubitce ); the body flattened beneath, broadest in the middle 
and tapering slightly toward the head, but more rapidly toward the 
posterior extremity. They are mostly under medium size, and are 
true borers, living in the interior or in the bark of trees and 
shrubs; a few species residing in the stalks or roots of herbaceous 
plants. 
They usually form a rude oval cocoon of their borings, in which 
to undergo their transformations. The pupae are brown, with trans¬ 
verse rows of short teeth on the abdominal rings.
