S ? . IIarj)e (PI. XXXV. f. 26) strongly dentate, prodnced 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 subventral longitudinal band connected with each 

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

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

 pattern of Lepidoptera. It was Elmer's main contention that longitudinal ba7ids 

 represent a/iccDj.s the ancestral pattern, which is erroneous.

(??. Eye lashed. Foretibia spinose. No pulvillus. Abdominal segments 

 laterally black at the apex ; white or grey at the base. Harpe without patch of 

 suberect scales ; penis sheath ])roduced distad into a simjile or hooked jirocess. 



A large genus, com])rising forms which ditfer considerably in structure, but are 

 connected by intergraduate species. 



Tongue much longer, or shorter, than the body. Palpus more or less 

 rough, with long hair-scales. Antenna of ? without distinctly prolonged seriated 

 ciliae, often obviously clubbed. Foretibia always armed with spines, but the 

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

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

 often with one or more spines {rancoucerensis, eremitus, etc.) ; first protarsal 

 segment variable in length, often armed with prolonged spines ; midtarsal comb
