BY EDWARD P. VAN DUZEE. 



The present is a first attempt to catalogue tlie described North 

 American i'orius of the h)wer families of the Homoptera-Cicadina. 

 Although doubtless incompleted, in some respects, i-t is hoj)ed that it 

 may prove of value to the American students of this group of insects. 



The classification and arrangement here adopted is substantially 

 that proposed by the writer in his "Synopsis" published in these 

 Transactions, vol. xix, pp. 21)6-300, December, 1892. The super- 

 family term there suggested includes those families in which the hind 

 tibite are niultispinose. These in our North American fauna are 

 Ulopidjfi, Ledridse, Bythoscopidse, Tettigonidae and Jassidae. The 

 first of these might, perhaps, be removed from this series, and the 

 second united with the Tettigouidte as a subfamily of equal value 

 with Gyponina and Tettigonina. The position assigned to family 

 Bythoscopidae is purely arbitrary, as it strictly i)arallels the Jassidae, 

 to which it is allied by Macropsis, and in a linear arrangement might 

 with equal propriety follow the Tettigonidae. 



No pains has been spared to bring the synonymy up to date, and 

 it is believed that the catalogue represents very nearly the present 

 state of our knowledge of the North American Jassoidea. The ar- 

 rangement of the references under each species is intended to exhibit 

 its history from its first publication to the present time, giving the 

 authority for each change and the date of its })ublication. 



In the case of the genera and higher groups references will be 

 fouinl to all the more im[)ortant European works. Where a species 

 occurs also in Europe this has not been attempted, but in the works 

 cited will be found a good description, or at least full references, 

 from which the literature of the species may be easily ascertained. 

 All references to the American literature of the group has been in- 

 cluded, except in the Typhlocybina, where no attempt has been made 

 to complete the record, nor has any search been made through the 

 voluminous literature on economic entomology issued by the numer- 



TRANS, AM. ENT. SOC. XXI. JULY, 1894.
