SOUTH AMERICAN BLATTIDAE FROM THE MUSEUM NATIONAL 

 D'HISTOIRE NATURELLE, PARIS, FRANCE. 



BY MORGAN HEBARD. 



Having recently reported on the undetermined American Der- 

 maptera of the Paris Museum, ^ the undetermined American Blat- 

 tidae were next sent us for study by Monsieur Lucien Berland of 

 that institution. The North American material does not include 

 any large collections and will be reported on in several papers based 

 largely on the Philadelphia collections and now in the course of 

 preparation. 



The South American series, on the other hand, proved to be large 

 and intensely interesting. As it was almost entirely from three very 

 distinct regions (French Guiana, southeastern Brazil and northern 

 Argentina), we have prepared a single report on the collections, divid- 

 ing it into three sections on a geographic basis and have included 

 material of our own collections which had not previously been 

 studied. 



The series sent by the Paris Museum has been returned, with the 

 exception of sets of duplicates, now in the collection of the author, 

 deposited at The Academy of Natural Sciences of Philadelphia. 

 We have also been most generously permitted to retain certain 

 unique individuals of previously known species, of great importance 

 in our futher studies on the subject. For these, an equivalent in 

 other material has been sent the Paris Museum. 



The 637 specimens recorded represent 49 genera and 99 species, 

 of which 8 genera and 34 species are described as new. 



We wish to thank most heartily. Monsieur Lucien Berland and 

 Docteur Lucien Chopard, for their kind assistance in affording us 

 the opportunity to study this material. 



Section I. French Guiana. 



This series represents the first large collection of Blattidae to be 

 studied from French Guiana. The series includes 103 specimens,
