HYPHINOE.—TOMOGONIA. 79 
thus, Mr. Butler (Cist. Ent. ii. p. 345) notices that he has erroneously referred Hemi- 
ptycha (Hyphinoé) placida, Germ., to Pyranthe. 
ICTARANTHE, gen. nov. 
Brevis, robustus, capite fere eque longo ac lato, ocellis inter se paullo magis quam ab oculis distantibus, his 
magnis, prominulis ; pronoto dorso late rotundato, convexo, haudquaquam carinato, cornibus modicis sat 
reflexis, lateribus ad margines profunde semicirculariter impressis ; tegminibus areis discoidalibus duabus 
interiori multo majori. 
Short and robust; the head about as long as broad, with the ocelli a little more distant from one another than 
from the eyes, which are large and rather prominent; the pronotum has the back broadly rounded and 
convex, and the sides deeply impressed in a large semicircle at the margins; the outer of the two 
discoidal areas is very much smaller in proportion to the inner than is usual in the allied genera. 
This genus is closely related to Pyranthe, Stal, from which it differs in the position 
of the ocelli, and the deep and regular impressions of the sides of the pronotum ; from 
most of the species of that genus it may at once be known by its convex dorsum, but 
Pyranthe flavo-marginata resembles it in this respect. 
1. Ictaranthe latifrons, sp.n. (Tab. VI. figg. 9, 9a-c, 2.) 
Brevis, sat latus, testaceus, cornibus pronoti apicem versus nigricantibus; capite fere levi, metopidio lato, con- 
vexiori, leviter punctato, cornibus modicis infra nigro-carinatis ; pronoto luteo, impressionibus ad margines 
dilutioribus, lateribus ipsis pone medium in processum acutum sinuatim contractis, apice nigro; tegmi- 
nibus hyalinis, margine exteriori infuscaté; corpore subtus fusco-testaceo; pedibus testaceis. 
Entirely testaceous, with the exception of the upper apical portion of the horns above, and a line underneath 
reaching to the margins, as well as the apex of the pronotal process, which are black or brownish-black ; 
the outer portion, also, of the lateral impressions on the pronotum is whitish-testaceous ; the head is almost 
impunctate, and the pronotum is more strongly punctured at the sides than on the disc; the lateral 
impressions are very distinct if viewed from above, and give the upper surface the appearance of being 
contracted in the middle, as is often the case with Ceresa; tegmina hyaline, with the extreme base dark 
and punctured, and the external margins infuscate ; legs testaceous. 
Long. cum tegm. 9 millim.; lat. int. corn. 6 millim. 
Hab. Panama, Bugaba (Champion). 
One female specimen. This insect, at first sight, very strongly resembles certain 
species of Ceresa, and it was sent to me placed among specimens of that genus. — 
TOMOGONIA. 
Tomogonia, Stal, Ofv. Kongl. Vet.-Ak. Férh. xxvi. p. 258 (1869). 
This genus contains two species, one from Guatemala and another from Colombia ; 
the former of these is the Smilia vittatipennis of Fairmaire, which superficially 
resembles a Ceresa, from which genus it is at once distinguished by the venation of 
the tegmina.
