1104 THE BUTTERFLIES OF NEW ENGLAND. 



inony ? of a harmony which appeals to savage and to sage ? There has yet 

 to be brought forward one single line of evidence to show that natural 

 selection or any other purely natural, law-constrained force can, uncon- 

 trolled, produce or even sustain that harmony of tint and design which 

 each of the whole tribe of butterflies displays on its individual surface ; a 

 harmony so infinitely extended when comparisons are begun that the 

 eternities would not suffice to exhaust them ; a harmony pervading the 

 utmost minutiae, which the unaided eye cannot perceive ; a harmony 

 appealing at every point to the aesthetic sense of the highest creature we 

 know, doubtless also to many a lower one whose physical and psychologi- 

 cal acquirements permit it. The untrained child but rarely and acciden- 

 tally touches a chord upon the piano ; so the undirected play of natiu-al 

 forces with color would ofteneat be misdirected ; and where is the selection 

 that shall bring about the survival and perpetuation of the harmonious ? 

 Nay, that has done it ! Every part of the animal frame, the entire oecon- 

 omy of the animal kingdom, the aesthetics of the animal universe, past 

 and present, point to an infinite and eternal directive force, guiding all 

 forces ; to an infinite, uplifting power, which we may trust. 



Table of species of Etirymus, based on the eyg. 



Quadrangular cells between tlie vertical ribs more than three times as broad as high 



philodice. 

 Quadrangular cells between the vertical ribs about twice as broad as high. 



Punctuations of surface circular interior. 



Punctuations of surface long-oval, more or less confluent eiirytheme. 



Table of species, based on the catei~pillar at birth. 



Laterodorsal dermal appendages with no stalk, enlarging uniformly from the b.ase, a.s broad at 

 tip as high. 

 Apical enlargement of dermal appendages in the neighborhood of the stigmata much longer 



than broad and pediceled Interior. 



Apical enlargement of derm.il appendages in the neighborhood of the stigmata of equal 



length and breadth, sessile philodice. 



Laterodorsal dermal appendages with a short stalk, the enlarged portion as broad at tip as high , 

 and twice as long as the stalk eurytbenie. 



Table of species, based on the mature caterpillar. 



Darker color following the under edge of the pale stigmatal stripe collected into distinct vel- 

 vety black dashes in the middle of most of the segments philodice. 



Darker color below the stigmatal band generally almost equally distributed, or at the most form- 

 ing only obscure blackish fuscous dashes in the middle of the segments eurytheme. 



Interior not seen. 



Table of species, based on the chi-ysalis. 



Surface vermiculations comparatively coarse ; posterior lateral corners of the head above next 

 base of antennae, smooth, glistening, slightly elevated; colors on either side of the lateral 

 ridge of the frontal projection ilightly contrasted .' philodice. 



Surface vermiculations comparatively delicate ; posterior lateral angles of the head like the 

 rest of the surface, scarcely elevated ; colors on either side of the lateral ridge of frontal pro- 

 jection strongly contrasted eurytheme . 



Interior unknown.
