FAMILY YPONOMEUTIDAE 
“ Thus hath the candle sing’d the moth.” 
Shakespeare.— Merchant of Venice , I, 9. 
This is a family of moderate size, represented in our fauna by 
twenty-two genera and over sixty species. The species have a 
characteristic facies, which when once recognized will enable the 
student to readily separate them from their allies. We are able 
to figure only three species, owing to the necessary limitations 
of space.
