Var? tsedata, Lee. Rep. P. R. R. Exp., p. 70. — Smaller, spots mostly brown, 

 and sub-confluent, punctuation fainter. 



California. 



This variety or race seems pretty constant in California ; I have seen, 

 however, equally small faintly punctate specimens from South Caro- 

 lina and Texas; these latter have an especially different look, hut I 

 think they are all varieties of the common species. Boheman (Eugen. 

 Resa., p. 203) has described it again as P. 'lO-signata from Taite (!), 

 and as P. interspersa from Sydney (!).
