^ The Pupa. 



The pupa differs hardly at all from the other Panax moths. 

 cephaHc plate is rather short, 

 and about as long as wide at 

 its base ; the lateral cornua are 

 well developed, and are about 

 equal in length to that of the 

 plate ; in some of the Dunedin 

 specimens, however, they were 

 not free, but soldered down to 

 the headpiece around the front 

 of the base of the cephalic plate. 

 There is a strongly marked mid- 

 dorsal ridge on vertex, meso- 

 and meta-thorax, and extending 

 slightly on to the first abdo- 

 minal segment. The prothorax 

 is narrow. Antennae variable 

 in length, sometimes slightly 

 longer than the body. Setae exactly as in P. 'panacivermiforma
