 byliformis and S. Fuciformis, which arc much more 

 like the ordinary Caterpillars of the Sphingidcc than

 different kinds of Galium. These Moths will at first 

 appear to a casual observer much more like Bees 

 or Hornets than Moths, from their wings being 

 without the usual scales, and consequently trans- 

 parent, except at the borders. The detection of the 

 indubitable characteristics which mark them as true 

 Moths will serve as useful lessons to the student in 

 acquiring habits of accurate observation.
