Of his Fulgorida, Stal characterizes a great number of genera, and gives 
the following synonymic indications : — He adopts the generic name LateV- 
naria (ascribed to Linne) for Fidgora (auctt.), and applies Fulgora to Iloti- 
nus (A. & S.) ; Metanira (StEl) = Desudaha (Walk.) ; Calyptoproctus (Spin.) 
= Paralystra (Walk.). The Dictyopharida also include many genera, among 
which Simotettix (Stal) = Nematophora and Fhaphiophora (Schaum) ; Die- 
tyophara (Germ.) = Pseudophana (Burm.), Chaintlius (Kol.) and Nersia 
(St§,l). Of the Cixiida, Botliriocera (Brnm.) — Adana (StSl) ; Brixia (StSl) 
= Triopsis (Sign). Of the Delphacida, Dclphax (Fab.) as restricted by St§,l 
= Areeopus (Spin.) ; Copicerus {^y^axiz) — Holotus (Gu^r.)= Jerw/a (Walk.) ; 
Hygiops (A. & S.) = Ugyops (Gu^r.) = Bidis (Walk.) ; Tropidocephala 
(St§,l) = Nephropsia (Costa). The Achilida include the genera Achilus 
(Kirby), Helicoptera (A. & S.), referred to the Flatides by Amyot & Serville, 
and several others proposed by St§J ; St5,l’s genus Diacira receives the new 
name of Sevia (1. c. p. 181). Among the Tropiduchida all the tabulated 
genera are of Stal’s own proposition ; but he also refers to this group Monop- 
sis (Spin.), Lcusaha, Iliracia, Epora, and Ficarasa (Walk.), and Eutropistes 
(Schaum) ; Ficarasa (Walk.) is very nearly allied to Tropiduchus (StSl) = 
Euria (Walk.). Among the Derhida, Herpis (Stal) is changed to Lamenia 
(StRl). The Lophopida include Lophops and Elasrnoscelis Lacusa and 
Py villa (StSl); the latter =Z«me7a (Walk.), Serida (Walk.), and Corethrura 
(Hope) ; Lophops = Cystingocephala (St§,l). The Issida include a great num- 
ber of genera, several of which are new. Among the Ricaniida, Nogodina 
(StSl) = Mindura (StSl) = Miriza (St®l) ; Ricania (Germ.) Scolypopa 
(StSl), and includes Pochazia (A. & S.), Tarundia (StSl), Mulvia (StSl), 
Deraulax (Sign.), Pocharica (Sign.), Pochazoides (Sign.), and Privesa (Stal) ; 
Pochazia oculata (Sign.) changed to Ricania luctifera (Stal), 1. c. p. 228. 
Of the Fiatida, Phromnia (St§,l) = Plata (A. & S.) ; Plata (Fab., Stal) = 
Colobcsthcs (A. & S.), and includes Cromna (Walk.) and probably Phylly- 
phanta (A. & S.) ; Pseudqflata (Gu^r.) = Datapax (A. & S.) ; Flatoides
