part of Macropsis, Lew.,^n which is inckided Mact'x/jjsis Jiavi- 



collis (Linn.), Lew. ; and {ifjPediopsis, Burm. part ois%Iacropsis, 



Lew., with type BijtJioscopus tilice, Germ.* A^ lanio is scarcely 



to be separated generically from microcephala, Schaff., Batraco- 



morplms becomes a synonym of Bythoscopus, Germ., Lew. Li 



1843 Amyot and Serville (* Hemipteres ') named Icuug as the type 



of Maa-opsis, notwithstanding that it did not conform. to Lewis's 



description, and had ah-eady been fixed as type oV Bythoscopus 



by Lewis. The type of 'Macropsis has, in fact, never been 



properly fixed. It must be either (1) fiavicollis or {^'pvirescens. 



I now fix it as the former as least objectionable. The name 



lAlacropsis, Lewis, cannot be used iordanio and its congeners, 



because it was, as stated above, founded for two species only, 



neither of which belongs to the same genus ns^lanio. The 



synonymy will then be : — 



(1.) Bythoscopus, Germ., 1833, type lanio (Linn.), Lewis. 



—^Batracoiiiorphus, Lewis, 1835, ^type [irroratus, 

 Lew. — ] ^micyDcephala, Schaft*.

4. Van Duzee adopts the generic name Lib urnia,Stk\, for 

 O pellucida, &c. He is certainly correct in not employing De//>/w a;, 

 Fabr., as has Puton in the fourth edition of the Catalogue of 

 Palaearctic Khynchota. 



The type of Delphax must be eiiheY Cicada claviconiis, Fabr., 



or Cicada crassicornis, Fabr., for these two were the only species 



included in the genus at its foundation in 1798. The former 



was fixed as the type oiOisii-aca, Latreille (1796), in 1810. I 



yhave not yet been able to trace a proper type-fixation io^PDelphax. 



^ Lihuviiia, Stal, 1866, is preoccupied hyl^mholoplipora, Stal, 1853 



(not Emholopliora, as Stal himself writes it later), and the latter 



name should be used. The somewhat complicated synonymy 



therefore stands : — 



'■ (1.) AsiRACA, Latr., 1796, type clavicornis (Fabr.), Latr., 1810. 



= ? Delphax, Fabr., 1798 (typical). 

 " (2.) Arz-eopus, Spinola, 1839/ type crassicornis (Fabr.), Spin. 



= ? Delphax, Fabr. 1798 (typical). 

 ° (3.) Embolophpora, Stal, 1853, 

 o = Liburnia, Stal, 1866. 

 o = Delphax, mod. auctt.
