30 THE COMMONER BUTTERFLIES. 



stages tiud full accounts of the habits, perhaps half of the 

 text being given up to these latter features. The figures, 

 54 of them, are, with 9 exceptions, woodcuts and remark- 

 able examples of the woodcutter's art, all being engraved 

 by Henry Marsh. 



Two other books of my own may be mentioned here, 

 since they deal largely with the life-histories of our butter- 

 flies. The first * is based upon a course of lectures upon 

 butterflies in general, and has something in particular to 

 say about 74 of our butterflies, with figures illustrative of 

 many of them. The other f treats in the fullest possible 

 manner of the structure, life-history, distribution, and habits 

 of a single butterfly, Anosia plexippus, at every point draw- 

 ing comparisons witli others, so that it serves in a measure 

 as a popular introduction to all. 



Finally, attention may be directed to three or four works 

 whicli deal almost exclusively with thebutterfly stage and 

 give descriptions either of all our known species or of all 

 found in a definite portion of our country. The first I pre- 

 tends to be nothing but a compilation of published de- 

 scriptions (many of them translations from the French) 

 arranged in a systematic order, pieceded by a very meagre 

 key to the genera. It contains 240 species, but is now 

 quite out of date. 



The second § is an original systematic description of the
