Xylorictidae 



FAMILY XYLORICTID/^ 



A small family which contains in our fauna two genera and 

 nine species. The group may be represented by Stenoma 

 schlaegeri Zeller, which is portrayed on Plate XLVlll, Fig. 41, 

 by a male specimen. The insect is very common in the Appa- 

 lachian subregion, and is particularly abundant in western 

 Pennsylvania. 



FAMILY CECOPHORID/E 



" Entomology is a science, not a pastime." — Westwood. 



This is another comparatively small family of interesting in- 

 sects, numbering in our f;iuna about ninety species, which are 

 distributed into thirteen genera. We can represent only a couple 

 of them, for the purpose of showing the readers of " The Moth 

 Book " what they are like.
