IV PREFACE. 



name, the name of the sub-genus enclosed in brackets, and 

 under the sub-genus will be found a reference to the genus ; for 

 example: under the genus Phalangopsis we find the species 

 gracilipes, Avhich was referred by Haldeman to the sub-genus 

 Daihinia; this is made clear in the following way: — 



Phalangopsis. 



gracilipes [Daihinia] IIald. Proc. Amer. Ass. Adv. Sc. II, 346, Penn. 



while under the genus Daihinia, after the mention of the dif- 

 ferent species, will be found the words, See also Phalangopsis. 



Great pains have been taken to give the localities in full and 

 to include in the list all references to such general localities as 

 "America" or "the Indies," even when it was uncertain whether 

 North America or the West Indies — the field embraced in 

 my scheme — was intended. References to "meridional" Amer- 

 ica are also included, because authors have frequently embraced 

 in this term Honduras and other parts of Central America. 

 I have excluded every case where no reference to my field was 

 made, even if subsequent investigations proved that the insect 

 occurred within those limits or the name itself suggested the 

 locality. CEdipoda Carolina presents an exaggerated instance 

 of this kind. Stoll' figured the insect under the name of 

 Locusta Carolina, but did not state where it was found ; this is 

 indicated by the name, but I have omitted reference to it and 

 similar cases, for the sake of making the work strictly one of 

 compilation. 



In the sequence of authorities under each specific name, a 

 chronological arrangement has been attempted, but works 

 quoted from a single author will succeed one another. 



Finally, to assist the young naturalist in the more ready use 

 of the list, I have added a tabular view of an Ortbopteran Sys- 

 tem, derived mainly from Burmeister's Handbuch der Entomol- 

 ogie, but including only the genera mentioned in this list, 

 I have, however, altered the sequence of the families to what I 

 conceive to be a more natural method.
