Obs. Allied to P. gambrisius, Fabr., but much larger,

 colour of discal spots. In the former the spots between 

 the first and third median nervules are very large and 

 almost fill the interspace, whereas in P. thesaurus they 

 are very much smaller and of different shape ; the one 

 between the first and second median nervule is long and 

 narrow, and does not occupy more than one-third of the
