14 HEMIPTERA-HOMOPTERA. 
2. Tropidoscyta uniformis, sp.n. (Tab. I. figg. 20, 20a, 20.) 
Precedenti affinis, sed brevior, pronoto multo fortius punctato, carinisque lateralibus supra oculos distinctius 
elevatis ; colore obscuriori, tegminibusque totis fuscis facillime distinguendus. 
Very like the preceding, but smaller and shorter, black or almost black in colour, with the pronotum very 
coarsely punctured, and with the lateral carine above the eyes strongly marked ; the tegmina are entirely 
fuscous, with the apex not hyaline, though slightly lighter than the base ; the legs are fuscous. 
Long. 4 millim.; lat. max. 23 millim. 
Hab. Panama, Boquete, Bugaba, Volcan de Chiriqui, Caldera (Champion). 
A specimen from Boquete is figured. 
LEIOSCYTA, gen. nov. 
Genus Tropidoscyte affine, sed pronoto angustiori et longiori, carinisque lateralibus supra oculos deficientibus ; 
tegminibus areis duabus discoidalibus, venisque minus elevatis instructis. 
Allied to Tropidoscyta, but with the pronotum narrower and more elongate in 
proportion, and more parallel-sided if viewed from above; the upper surface, too, is 
smoother; the small carine over the eyes are wanting; the tegmina have only two 
discoidal areas, instead of three as in Zropidoscyta, and the veins are less raised and 
sometimes almost obsolete in the middle. The type of the genus is Zropidoscyta 
pallidipennis, Stal. |

Tropidoscyta pallidipennis, Stal, Kong]. Sv. Vet.-Ak. Handl. Band viii. 1, p. 46°. 
Hab. Mexico! (Mus. Holm.; Sallé), Cuernavaca and Puebla (Bilimek, in Mus. Vind. 
Ces.). 
An example from the Stockholm Museum is figured. 
2. Leioscyta cornutula. (Tab. I. figg. 22, 22 a.) 
Tropidoscyta cornutula, Stal, Kongl. Sv. Vet.-Ak. Handl. Band vii. 1, p. 46°. 
Hab. Mexico! (Mus. Holm. ; Sallé). 
The female only is known. 
This species is closely allied to the preceding, but differs in having the front of the 
pronotum more porrect and extended into a very short blunt horn. It is quite possible 
that they may be sexes of one species; but I have only been enabled to examine one 
specimen of each. 
3. Leioscyta nitida, sp.n. (Tab. I. figg. 23, 23a, 23 6.) 
Nigra vel fusco-nigra, nitida; pronoto fortiter punctato, carina centrali acute elevaté plus minusve distincte 
albo-notata, et utrinque carina distincté sed minus elevata, instructo, lateribus supra oculos quoa dearinas 
levibus ; tegminibus nigris ad medium opacis, apice abrupte et lsete hyalino; pedibus nigris, genibus 
tarsisque dilutioribus vel totis fuscis. 
A small, black, very shiny species, with the prothorax strongly and distinctly punctured, tricarinate, with the
