Faunal Relations 



The Mesostenini in America north of Mexico comprises 39 known 

 genera, 235 species, and 73 additional subspecies. According to 

 faunistic relations, the genera may be divided into the three series in 

 which they are discussed below: 1, Holarctic group; 2, Sonoran 

 group; 3, Neotropic group. Reptatrix and Cryptohelcostizus are the 

 only genera restricted to our area. Of these it is probable that the 

 former and certain that the latter will prove to occur also in the 

 Mexican fauna. 



Holarctic: This group of genera includes Apsilops, Agroihereutes, 

 Gamhrus, Arifranis, Pycnocryptus, Ischnus, Habrocryptoides, Trachy- 

 sphyrus, Hidryta, Idiolispa, Trychosis, Hemisphragia, Listrognathus, 

 Mesostenus (Transfuga Group), Acroricnus, Xylophrurus, Echthrus,
