STUDIES IN THE DERMAPTERA AND ORTHOPTERA 

 OF COLOMBIA 



FIRST PAPER 



Dermaptera and Orthopterous Families Blattidae, 

 Mantidae and Phasmidae 



BY morgan HEBARD 



In undertaking the study of Dermaptera^ and Orthoptera from 

 Panama, we have found that a good beginning has been made 

 for Costa Rica, to the north of that region, but for Colombia, 

 to the south, all that appear in the literature are scattered de- 

 scriptions of new species or records of previously known forms. 



In consequence, in order to have a better understanding of this 

 portion of the Colombian fauna, we have assembled all the mate- 

 rial available from the country and present in the present paper 

 the results for the Dermaptera and first three families of the 

 Orthoptera. 



The series at hand are much smaller than is desirable and it is 

 patent that only a fraction of the Colombian species are repre- 

 sented. The material is, however, much more representative 

 than any previously reported and furnishes striking evidence of 

 the multitude of species which occur in that country, so varied in 

 topography and environmental conditions. 



The lack of previous study is shown by the fact that of the 

 seventy species here considered, thirty-five are new to science, 

 these including nine new genera. Two hundred Colombian speci- 

 mens are recorded, in addition to which a number of exotic 

 specimens of the same or allied species are discussed. We wish 

 to extend our hearty thanks to Mr. James A. G. Rehn, of the 

 Academy of Natural Sciences and to Mr. A. N. Caudell, of the 

 United States National Museum, for the privilege of studying 

 the Colombian material under their care. 



We would note that the Colombian series is comprised of a 

 few small collections and a number of individuals from widely
