altogether unnatural, as one would expect to find it, founded solely upon 

 a few characters drawn from the neuration of the wings," adding, " an 

 excellent opportunity for inaugurating a new and more substantial classi- 

 fication is now open to the general student." Instead of genera, say 

 genera and families. In my view, the Pieridte torm a natural family, the 

 Parnassid;^ another. After these come the Erycinida; and Lycfvnida-, 

 then the Nymphalidse, with Satyrinsv next the Hesperidpe. With this 

 arrangement, the " curious resemblances " noticed by Mr. Scudder in all 

 the four stages of the Satyrinae to the Hesperidpe puzzle no longer ; the 

 " phyletic meaning-' is intelligible, and we can admire the fitness of 

 things in general. 



Erratum. — The word " turned,"" on page 66, line 13 from top, should read 

 'tumid."
