AUTHOR'S PREFACE. 



IN the Preface to the first volume of Lepidoptera I announced 

 my intention of completing the Butterflies in two volumes ; 

 but the amount of matter which I found it necessary to include 

 proved more considerable than I had expected, and the present 

 volume includes only Families II. to VI. of the Butterflies, viz., 

 Libytheid&i Lemoniidce, Lyccenida, Pierida, and Equitidce ; the 

 Hesperiidtz being left over till the third volume. 



As at present arranged, it is proposed to devote three 

 volumes to the remainder of the Lepidoptera, making five in 

 all, divided as follows : 



Vol. I. BUTTERFLIES : Nymphalidae. 

 ,, II. Libytheidae to Equitidoe. 



,, III. ,, Hesperiidae. 



MOTHS : Pages, Burnets, Tiger-Moths, &c. 

 IV. ,, Hawk-Moths, Emperors, &c. 

 ,, V. Owl-Moths, Loopers, Clothes Moths, &c.

 state, never having been sub-divided into genera like the 

 other Families. A thorough revision would have been be-

 for any portions of this extensive Family, collated them with
