ON DERMAPTERA AND ORTHOPTERA FROM SOUTH- 

 EASTERN BRAZIL 



BY .)A.ME8 A. G. REHN 



The material treated in the followina; pages was submitted to 

 us for study by Dr. Herman \'()n Ihering, formerly Director of 

 the Museu Paulista at Sao Paulo, Brazil. The first set of the 

 material, aside from the types of the new species, has been re- 

 turned to that institution, the remainder being retained, with 

 the types of the new forms, in the collection of the Academy 

 of Natural Sciences of Philadelphia. 



The material studied has a particular appeal to us, as, while 

 it is from a numl)er of localities, it furnishes a considerable amount 

 of data on the eastern distri])ution of many types of Orthoptera 

 occurring in the Parana drainage, and also gives a fairly clear 

 idea of the relatively narrow area of disti'ibution of many of the 

 coast forms. The present paper presents merely the systematic 

 study and the geograi)hic data of the material, but at a later 

 date, in with other information, we hope to more ci'itically dis- 

 cuss the important features apparently governing the distribu- 

 tion of the Dermaptera and Orthoptera 'of southeastern Brazil. 



The localities represented in the collection, with their position 

 as far as we can ascertain from the charts and information avail- 

 able,^ are as follows:

' Much of our information relative to localities in the State of Sao Paulo has 

 been gathered from: "'Apontamentos Historicos, Geographicos, Biogra|)hicos,
