■Without any reference to the accepted classification of families, a 

 simple tabulation of the few species examined is added, based purely 

 on these variations in the structure of the prothorax. The grouping 

 coincides in the main with the general classification. The Papilionidse, 

 however, show the most striking variations. In Nymphalidae, the 

 sub-family Heliconidte comes nearer to the Papilionid^ than the other 

 groups. Of the species in Lycaenidse and Hesperidae examined there 

 is reasonable uniformity of structure.
