6 THE BLATTIDAE OF PANAMA 



We wish to thank most heartily Mr. A. N. Caudell of the 

 United States National Museum for the opportunity to study the 

 material belonging to that institution, and Mr. James A. G. Rehn, 

 whose unceasing energy has now built up an extremely extensive 

 determined collection at the Academy of Natural Sciences of Phil- 

 adelphia, invaluable for reference in studies such as the present. 



In the present paper eight hundred and ninety-four Panamanian 

 specimens are treated, representing forty-seven genera and ninety- 

 three species and races, of which ten genera and thirty-seven 

 species are described as new. 



From the literature we find that ten additional species have 

 been recorded from Panama, bringing the total of genera and spe- 

 cies known from that region to fifty-three genera and one hundred 

 and three species. These species are tabulated below, their known 

 distribution in North America, Panama, South America and the 

 West Indies being indicated by asterisks, those having close affin- 

 ity to other species occurring in the area checked being indicated 

 by an "a". 



We would remark that but two species, not including those 

 generally distributed through all or the greater portion of tropical 

 America, are also found in the West Indies, that forty-nine are 

 known only from Panama, twenty-five from Panama and north- 

 ward, nine from Panama southward and eighteen from Panama and 

 North and South America. Two species are known from North 

 and South America but have not yet been found in Panama. 



Though we find the influence from North America stronger than 

 from South America in the Canal Zone, we do not believe it to be 

 as much greater as is indicated by the above figures, considering 

 that a much greater amount of work has been done in Central 

 America than in northern South America.
