McAtee — Genera of the Eupterygidae. 115 



adjective in the genitive, will always have a genitive ending irrespective 

 of the genus to which it may he assigned. No change in nomenclature 

 therefore will make the two names exactly alike ; hence they would appear 

 to differ sufficiently so that both may be retained. Advocates of the 

 "one-letter rule," at least, will take this view. 



1862. EMPOASCA. Walsh, Benj. D. Fire-blight. Two new foes of 

 the apple and pear. The Prairie Farmer, 10, No. 10, Sept. 6, 1862 

 (Entomological note, pp. 148-9), p. 149, Fig. V. Reprinted with 

 slight changes in Proceedings of the Boston Society of Natural His- 

 tory, 9, Feb. -March, 1864, p. 315. 



Described to include the new species E. viridescens, E. consobrina and 

 E. obtusa op. prim. cit. p. 149. 



Distant, 1908, cites* as genotype E. viridescens Walsh, a valid designa- 

 tion. Oshanin, 1912, statest that Cicada smaragdulai is the type of this 

 genus. This of course is incorrect as smaragdula is not one of the origin- 

 ally included species. 



Synonyms: Chloroneura Walsh, 1862 (in part); Chloria and Kybos 

 Fieber, 1866; Chlorita Fieber, 1872. Which see.

JKirkaldy's remark (Bui. 1, Part 9, Exp. Sta. Hawaiian Sugar Planters' Assoc, 

 1906, p. 357) that Sahlberg made this species the type of Cicadula is unfounded. Sahl- 

 berg's action (Notiser Fauna et Flora Fennica Forh. 12, 1871, p. 159) by no means can be 

 construed as fixation of a type. What happened is this : Fieber, 1866, removed to other 

 genera certain species of Zetterstedt's (1838) Cicadula complex; Sahlberg, 1871, merely 

 put some of them back, a procedure in no wise affecting ultimate disposition of the 

 genera, nor their nomenclature. Cicadula was definitely excluded from the Euptery- 

 gidae by type fixation, by Woodworth, 1888, if not earlier.
