(Plate XVII) 



The following summary of the geographical distribution of 

 the genus Erpetogomphus was published in 1905 (Calvert, 

 1901-19x38, p. 159) : "A very characteristic genus of the present 

 [Mexican-Central American] fauna. Eleven species are now 

 known, ten of which have actually been found in Mexico or 

 Central America. The eleventh, E. compositus, is known from 

 Texas and Arizona, and will doubtless be found in Mexico; 

 it has been reported from the Yellowstone and Oregon, which, 

 with Ohio and Indiana (E. designates), are the most northern 

 known limits of Erpetogomphus. To the south, Guatemala is

 record from Brazil."

 this genus certainly known is now San Jose, in Costa Rica, as
