1 88 NORTH AMERICAN BLATTIDAE 



serrations only showing traces of the discoidal development which 

 is so striking in that species. 



The present insect, though domiciliary, is frequently found under 

 signs on trees near the borders of towns in peninsular Florida. 

 This is the only region in the United States where the species is 

 known to be firmly established, though elsewhere along the south- 

 ern border, in the warmer portions, it may be brought in by com- 

 merce and become a permanent resident. The northernmost rec- 

 ords are Fernandina, Green Cove Springs and Cedar Keys, Flor- 

 ida. -^^ The species is circumtropical in distribution.

 and Zehntner. Those authors in the Biologia have evidently confused material of one 

 of the unicolorous species of the genus under truncata, designating such material as vari-

 this material represents P. Juliginosa. Biol. Cent.-Amer., Orth., i, p. 74, (1893).
