STATE LISTS 



The following lists have been prepared from the data incorporated 

 in the checklist. There are many literature records, not acceptable for 

 the checklist, that should be considered by students of the faunas of 

 political areas, for some of them, not now acceptable, can eventually 

 be interpreted more or less definitely in the light of further collections. 

 It is impossible to summarize all these accounts here. The lists that 

 follow include only well-verified records published in recent or defi- 

 nitely acceptable works, and for which specimens presumably are 

 available ; records, published in older works, that are reasonably reli- 

 able and identifiable; and data from specimens examined by us. 



All political areas are represented by one or more records. Ar- 

 ranged according to the number of species known from each, the sub- 

 divisions have the following sequence : 



Veracruz 98 



Oaxaca 98 



Guerrero 71 



Chiapas 70
