3 ?. Harpe (PI. XXXV. f. 20) strongly dentate, produced ventrad into a broad 

 lobe which ends in a heavy sharp tooth. The black lateral patches of the abdomen 

 have developed to a subdorsal and snbventral longitudinal baud connected with each 

 other by the black edges of the segmeutn. The development of such bands from 

 patches in this species is of great significance in the study of the development of the 

 pattern of Lepidoptera. It was Elmer's main contention that longitudinal bands 

 represent always the ancestral pattern, which is erroneous.

 connected by intergradiiate sjiecies.

 sjiines quite variable in number and size, midtibia unarmed, or with one or a 

 few apical sjiincs regularly or occasionally, or more or less spiny all over ; spurs 

 often with one or more spines {mncouvcrensis, cremittts, etc.) ; first protarsnl
