340 THE ENTOMOLOGIST. 



= part of Macropsis, Lew., in which is inckided Macropsis Jlavi- 

 collis (Linn.) J Lew. ; and (4) Pediopsis, Burm. part of Macropsis, 

 Lew., with type Bijthoscopus tilice, Germ.* As lanio is scarcely 

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

 morphus becomes a synonym of Bythoscopus, Germ., Lew. In 

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

 of Macropsis, notwithstanding that it did not conform to Lewis's 

 description, and had ah'eady been fixed as type of Bythoscopus 

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

 properly fixed. It must be either (1) Jiavicollis or (2) virescens. 

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

 Macropsis, Lewis, cannot be used for lanio and its congeners, 

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

 neither of which belongs to the same genus as lanio. The 

 synonymy will then be : — 



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



:= Batracomorjjhns, Lewis, 1835, type [irroratus, 

 Lew. —J microcephala, Schafi'. 



= Macropsis, auctt. 

 (2.) Macropsis, Lewis, type Jiavicollis (Linn.), Kirk. 



= Oncopsis, Burm., 1838, type tilice (Germ.), Burm. 



= Bythoscopus, auctt. 

 4. Van Duzee adopts the generic name Liburnia, Stal, for 

 pellucidcL, &c. He is certainly correct in not employing Delphax, 

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

 PalaBarctic Ehynchota. 



The type of Delphax must be either Cicada clavicornis, 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 of Asiraca, Latreille (1796), in 1810. I 

 have not yet been able to trace a proper type-fixation for Delphax. 

 Liburnia, Stal, 1866, is preoccupied hy Embolophpora, Stal, 1853 

 (not Emholophora, 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.) Ar^opus, Spinola, 1839, type crassicornis (Fabr.), Spin. 



= ? Delphax, Fabr. 1798 (typical). 

 (3.) Embolophpora, Stal, 1853, 



^ Liburnia, Stal, 1866. 



= Delphax, mod. auctt.
