68 HEMIPTERA-HOMOPTERA. 
15. Aconophora ensata, sp. n. (‘I'ab. V. figg. 14, 14.) 
Sat elongata, capite infuscato, marginibus dilutioribus, ocellis distincte inter se quam ab oculis magis remotis, 
pronoto testaceo distincte fortiusque punctato, humeris prominulis, cornu elongato, nigro, ad basin tenuiori, 
ad apicem evidenter dilatato ; apice prothoracis supra viso brevi minus acuto ; tegminibus piceis, teitia 
parte apicali fusco-hyalina, et macula indistinctaé ad medium testacea, colore tamen variabili et nonnun- 
quam dilutiori; pedibus totis ferrugineis, vel femoribus partim infuscatis; abdomine ferrugineo vel 
fusco-ferrugineo. — 
A somewhat long species, comparatively broad at the shoulders, which are prominent; head infuscate, with 
the margins more or less distinctly lighter; ocelli distant from one another; pronotum testaceous, with 
strong and distinct punctuation, and with a long black horn, which is slender at the base and plainly dilated 
at the apex; apex of the pronotum, if viewed from above, rather short and blunt; tegmina dark, with 
the apical portion fusco-testaceous, more or less hyaline, and with a testaceous spot more or less indistinct 
in the middle, sometimes, however, they are entirely fusco-testaceous with darker markings ; legs entirely 
ferruginous, or with the femora partly infuscate ; abdomen more or less dark. 
Long. cum tegm. 9-10 millim. ; ab humeris ad apicem cornus 4—6 millim.; lat. int. hum. 3 millim. 
Hab. Mexico (Bilimek, in Mus. Vind. Ces.), Atoyac in Vera Cruz (Schumann) ; 
Guatemata (Sallé); Nicaragua, Chontales (Janson); Panama, Bugaba, Volcan de 
Chiriqui (Champion). 
The peculiar shape of the horn and the contrast in colour between the pronotum 
and tegmina will easily distinguish this insect. The specimens in the Vienna Museum 
collection are larger than the others, and may possibly belong to a different species. 
A specimen from the Volcan de Chiriqui is figured.

Butler gives 4. hastata, Stal, as a synonym of A. lati¢ornis, which is an entirely 
different insect. Dr. Aurivillius has sent me a typical specimen of Stal’s species, which 
is identical with 4. prunitia. A. hastata (Fabr.) is allied to A. lata, and perhaps is 
identical with A. nigrivitta, Walk.; as there appear to be two species bearing tiie 
name of A. hastata, Butler’s name must be retained. 
In Signoret’s collection there are two specimens labelled A. hastata, Stal, one of 
which appears to be Walker’s A. concolor, and the other is allied to A. pinguis. In 
our collection there is a specimen from Omilteme, Guerrero, which either belongs to 
A. prunitia, or is very closely allied to it; the horn, however, is straight and level 
with the back of the pronotum, whereas in A. prunitia it forms an obtuse angle with 
it; the insect may belong to a new species, but is too close to A. prunitia to be 
described as distinct on one example. 
A Mexican specimen is figured.
