 between Newberry and Big Pine Key, Fla., the 86 specimens exam- 

 ined by Hebard having been taken at all seasons of the year and 

 principally beneath signs attached to trunks of pine trees. When 

 disturbed they seldom attempt flight, but run about to hide in 

 crevices in the bark or drop to the ground. The most northern 

 point at which it has been found is Newberry, Fla.

A tropical species of wide distribution taken in the United 

 States only at Miami and Key West, Fla. At the latter place 

 Rehn & Hebard found it in small numbers, July ?> 7, under the 

 counters of a fruit store, in folds of old burlap bags, where it had 

 as company four other species of circumtropical cockroaches. 

 It is a house-dwelling species, varies much in color, and according 

 to Shelford (1011 ) has been described under ten different specific 

 names besides the one it rightfully bears; the first record from 

 the United States, that of Rehn from Miami, Fla. (1003, 125), 

 being one of these, Plii/lhxlmiiihi ritlicnsix (Sauss.).
