112 HEMIPTERA-HOMOPTERA, 
CEDUSA, gen. nov. 
Brevis, vertice minimo, ante oculos vix producto, oculis infra emarginatis; fronte clypeoque perangustis ad 
medium modice ad latera fortiter carinatis ; pronoto brevissimo ; scutello convexo, subtiliter tricarinato ; 
tegminibus coriaceis, vena posteriori clavi apicem clavi haud attingente, vena transversa clavi venam 
posteriorem ad medium marginis clavi attingente; venis omnibus corii ante basim in unam conjunctis, 
vena radiali multo ante venam ulnarem interiorem furcaté; tibiis posticis simplicibus. 
Vertex very small, scarcely produced before the eyes, which are large and depressed, and emarginate beneath ; 
forehead and clypeus very narrow, about equal in length, with central and strong lateral keels ; pronotum 
very short, with three more or less distinct keels; scutellum convex, feebly tricarinate ; tegmina opaque 
and coriaceous, slightly dilated behind the clavus, with all the veins of the corium united into one vein 
before the base, and with the medial vein forked much before the inner ulnar vein, the posterior claval 
vein thick, not continued to the apex, the transverse claval vein joining this vein at about the middle of 
the clavus; wings with one transverse vein ; posterior tibie not spined. 
Although the tegmina in this genus are somewhat dilated behind the clavus, they 
do not overlap, but are tectiform, the hinder portion being somewhat elevated if 
viewed from the side. 
1. Cedusa funesta, sp.n. (Tab. XI. figg. 28, 28 a, b.) 
Parva, nigra, nitida, fronte clypeoque carinis testaceis; scutello levi, carinis subtilibus instructo, unicolori, 
interdum linea longitudinali ad medium obscure testaceaé ; tegminibus opacis, venis crassis ; alis fumatis ; 
pedibus dilute testaceis, tarsis fuscatis.

opaque, with thick veins ; wings smoke-coloured ; legs light testaceous, with the tarsi pitchy. 
Male with the last ventral segment straight, and the pygofer large and strongly developed, with the upper 
hook long and slender. 
Female with the last ventral segment produced into a broad triangular plate in the centre, and somewhat 
toothed and angled at the sides, 
Long. cum tegm. 44-5 millim.; lat. ad hum. 1-14 millim. 
Hab. Mexico, Atoyac in Vera Cruz (Schumann), Teapa in Tabasco, Xucumanatlan 
and Chilpancingo in Guerrero (H. H. Smith); Guatema.a, San Gerdénimo (Champion). 
We figure a specimen from Teapa. 
2. Cedusa venosa, sp.n. (Tab. XI. figg. 29, 29a.) 
Albescens, fronte clypeoque plerumque dilute testaceis; scutello testaceo, carinis colore dilutiori signatis ; 
tegminibus subpellucidis, testaceis, venis crassis albescentibus; alis lacteis; abdomine nigrescente ; 
pedibus testaceis, tarsis obscurioribus. 
Of a whitish-testaceous colour, with the forehead, clypeus, and pronotum mostly lighter testaceous; scutellum 
testaceous, with the keels marked by three light lines; tegmina semitransparent, testaceous, with thick 
light-coloured veins ; wings milky-white; abdomen pitchy; legs testaceous, with the tarsi darker. 
Female with the last ventral segment of the abdomen produced into a broad triangular plate, but not so much 
angled at the sides as in the preceding species. 
Long. cum tegm. 5 millim.; lat. ad hum. 14 millim. 
Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 
One female specimen.
