66 HEMIPTERA-HOMOPTERA. 
MALA, Purula and San Gerénimo in Vera Paz, Guatemala city (Champion) ; Costa Rica, 
Volcan de Irazu 6000 to 7000 feet (Rogers); Panama, Volcan de Chiriqui 4000 to 6000 
feet (Champion). | 
T have carefully examined the types of the above-named insects and have thought it 
best to regard them as belonging to one species, although future writers may be of a 
different opinion. I can, however, see no point on which to separate them, as in a 
large series they lead one into the other, and, in fact, some specimens, except for colour, 
very closely resemble females of A. laticornis. The males appear in all cases to have 
short pronotal horns and must be referred to A. concolor, Walk., whereas the females 
have long horns and must be referred to A. marginata and A. stabilis. Walker’s type 
of A. stabilis.is broken and scarcely recognizable, but, so far as can be judged, it is not 
different from his A. marginata. | 
A considerable : series of males and females have been received from Guatemala city. 
Var. eneosparsa. 
Aconophora eneosparsa, Butl. Cist. Ent. i. p. 348, t. 7. fig. 1 14%, 
Hab. Mexico (Bilimek, in Mus. Vind. Ces.), Volcan de Orizaba (Sallé*), Jalapa 
(Hoge); Panama, Volcan de Chiriqui (Champion). 
This is a rather large variety of A. marginata, of a greenish-olivaceous colour, with 
the pubescence more marked in some specimens; it is, however, connected by inter- 
mediate forms with the type-form, and cannot be regarded as more than a variety. 
11. Aconophora nitida, sp. n. (Tab. V. figg. 12, 12 a.) 
Brevior, pronoto nigro vel nigro-piceo, nitido, densius sat fortiter punctato, spatio inter humeros sat lato, 
sparsissime flavo-pubescenti, cornu brevissimo ; tegmenibus pubescentibus, fere totis nigris, apice exteriori 
late hyalino; pedibus ferrugineis, femoribus interdum ad partem piceis. 
A rather short species, broad between the shoulders, which are prominent, with the pronotum black or pitchy- 
black, clothed sparingly with golden pubesceuce, which is also present on the tegmina, except towards 
the apex; the horn is extremely short, and not broad at the apex; the tegmina.are pitchy-black, with 
a small patch on the costa and the interior third hyaline, the veins on the hyaline portion being testa- 
ceous; the clavus, moreover, is more or less testaceous; legs ferruginous or reddish-testaceous, with 
the femora sometimes partly pitehy. 
Long. 8-9 millim. ; ab humeris ad apicem cornus 32 millim.; lat. int. hum. 34 millim. 
Hab. PanaMa, Bugaba, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
This species is closely allied to A. hadina, Butl., from Brazil, but has the pronotal 
horn less produced, and is more shiny and less closely punctured. 
We figure a specimen from Bugaba. 
It is also closely allied to A. pugionata, Germ., from which it differs in much the 
‘same points as from A. hadina ; in fact, if the specimen of A. pugionata sent me from 
the Stockholm Museum is correctly named, I believe that 4. hadina and A. pugionata 
are identical, especially as both insects come from Brazil.
