 of the specimens is interrupted by an irregular space of the

 spöts, of ten very distinctly marked. Lower parts uniform 

 and extremities dark-banded.

 stinct differences between the development of the external 

 parts of this species and that of H. rufus (all specimens of 

 the different varieties of this one measured together).
