264 NORTH AMERICAN BLATTIDAE 



numerous adventive records of N. holosericea, probably, and the 

 two records of N. mexicana,^^^ from the United States and Canada, 

 apply to this species. 



In the present genus the immature females differ from adults of 

 that sex in having the subgenital plate strongly triangularly 

 produced dextrad, with apex rounded; in the early stages the 

 seventh ventral abdominal segment is not concealed, the styles 

 remaining visible.
