94 HEMIPTERA-HOMOPTERA. 
Dr. Goding informs me that this species is very near his Amastris stali, and it may, 
perhaps, eventually prove to be a variety of that insect; I have not, however, had an 
opportunity of examining the type. 
4. Hypamastris brunnea, sp. n. 
Brunnea, unicolor; capite antice obtuso producto, seepius fusco-notato; pronoto notis fuscis in metopidio supra 
oculos, quoad cetera unicolori, dense sat fortiter punctato, humeris prominulis, carina centrali distinct; 
tegminibus hyalinis, venis et margine externa testaceo-brunneis, apice haud infuscato; capite subtus fusco ; 
pedibus brunneis, ad partem infuscatis. 
Unicolorous brown, with the head obtusely produced, and the pronotum thickly and rather strongly punctured, 
with the shoulders slightly prominent, and the central keel distinct ; dorsum slightly uneven if viewed from 
the side; tegmina hyaline, not infuscate at the apex, with the veins and the external margin testaceous- 
brown, but with the apex not fuscous ; legs brown, the tarsi, the upper part of the femora, and the apex 
of the tibizw more or less fuscous. 
Long. cum tegm. 6 millim.; lat. 3 millim. 
Hab. Mexico, Oaxaca (Mus. Brit.: ¢ ). 
This species is allied to Z. segmentata, but is larger, and, apart from other differences, 
may be known by the absence of the darker segment of colour at the sides. 
5. Hypamastris variegata, sp. n. 
Nigra vel purpureo-nigra, albido variegata; capite leviter producto, albido, punctis et notis nigris; pronoto 
albido, distincte sat fortiter punctato, punctis nigris, macula magna in medio constricté’ majorem partem 
dorsi occupante, deinde vitté albida ante apicem, apice ipso nigro; tegminibus venis fuscis, margine 
externa testaceé; abdomine pedibusque nigris, albido variegatis. 
Of a black or purplish-black colour, variegated with white; head not so strongly produced as in H. brunnea, 
white, with dark punctures and dark markings at the sides; metopidium with dark markings over the 
eyes ; the ground-colour of the pronotum is white, the punctuation, which is distinct and rather strong, 
being dark; a large dark marking, shaped like an hour-glass, occupies most of the dorsum, behind which 
before the apex is a white band, the apex itself being dark; tegmina with the veins fuscous and the 
external margin testaceous; legs and underside dark, variegated with white. 
Long. cum tegm. 6 millim.; lat. int. hum. 22 millim. 
Hab. Mexico, Oaxaca (Mus. Brit.: 3 ). 
APHETEA, gen. nov. 
Brevis, lata, humeris obtuse prominulis, pronoto ad apicem sensim acuminato, haud nitido, dense punctato, 
dorso a latere viso vix sinuato, apice obtuso; tegminibus areis apicalibus quinque, ared centrali basali 
angustissima, apice sensim dilatato; alis areis apicalibus tribus magnis, discoidali nulla distincté; pedibus 
sat robustis, externe canaliculatis. 
Form short and broad, with the shoulders obtusely prominent, and the pronotum shield-shaped, gradually 
narrowed to the apex; tegmina with five apical areas, which radiate regularly from the slightly dilated 
end of the very narrow central basal area; the latter appears to be sometimes divided, but the point is 
not quite apparent; wings with three large apical areas and no discoidal area; legs rather stout, extremely 
deeply channelled. 
The position of this genus is very doubtful, but it seems to be allied to Horiola,
