will show the divisions under which I propose to deal with the 

 subject. 



TABLE OF VARIATIONS IN THE COLOR OF 

 LEPIDOPTERA. 



Aberrations or Heteromorphism. 



It will be seen from the diagram that I divide the twelve 

 classes into two sections, six classes in each. The first includes 

 mere aberrations, and the second variations of constant occur- 

 rence. To the first section I give the name of Heteromorphism 

 and to the second that of Orthopcecilism. 



The six heteromorphic variations are more of the nature of 

 Avhat gardeners call " sports," and in the natural state do not, as 

 a rule, form permanent varieties or races, although by careM 

 selection in confinement some of them may be perpetuated. 



The six orthopa3cilic variations are of constant occurrence, 

 and in a state of nature form permanent variations either of a 

 local, seasonal, or other character. 



I do not contend that these twelve classes are sharply sepa- 

 rated from each other, but, on the contrary, there are some 

 variations to be met with that might with equal propriety be 

 placed in more than one of the classes. 



I shall now consider the twelve classes separately. 



Albinism. — A pure albino amongst the lepidoptera is very 

 rare, and my cabinet contains but one specimen, viz., Eusehia 

 hipunctaria. This remarkable specimen I took myself at Lewes. 

 The only other albinos I have seen were captured in the Island
