64 HEMIPTERA-HOMOPTERA. 
which, in the first place, differs from Fairmaire’s description, and, in the second place, 
might be applied to several other species. 
6. Aconophora nigricornis, sp.n. (Tab. V. figg. 10, 10 a.) 
Olivaceo-testacea, pronoto dense et subtiliter punctato, parcius albido-pubescenti, cornu et apice pronoti nigro, 
illo lato, sat longo, suberecto, carina dorsali nigro-brunnea; capite nigro plus minusve flavo-limbato ; 
tegminibus hyalinis, venis nigro-brunneis ; pedibus totis testaceis. 
Of an olivaceous-testaceous colour (testaceous in slightly faded specimens), with the pronotum thickly and 
finely punctured, and, when fresh, apparently sparingly clothed with whitish fugitive pubescence, with 
the horn broad and porrect and entirely black or black-brown; the apex also of the pronotum: is 
black, and the narrow raised dorsal line black-brown ; the head is ‘black with yellow border, or yellow 
with the centre black ; the tegmina are hyaline, with the veins dark and with a slight shade of fuscous 
in one or two specimens towards the apex ; legs entirely testaceous ; underside partly dark. 
Long. 12 millim.; ab humeris ad apicem cornus vix 6 millim.; lat. int. hum. 4-millim. 
Hab. Mexico (coll. Signoret, in Mus. Vind. Ces.); GuaTeMaLa, Chiacam, and San 
Gerénimo in Vera Paz (Champion). 
We figure a specimen from San Gerénimo. 
7. Aconophora pinguis, sp.n. (Tab. V. figg. 11, 11a.) 
Piceo-castanea, pronoto crassiori, subtiliter subrugosius punctato, sparsim pubéscenti, cornu parvo tenui, vix 
erecto, dorso leviter rotundato, apice supra viso breviori; tegminibus fuscis, apicem versus hyalinis ; 
corpore subtus piceo; pedibus totis ferrugineis vel fusco-testaceis. 
Mas: cornu breviori et crassiori. - 
Femina: cornu longiori et graciliori. 
Of a pitchy-castaneous colour, with the pronotum rather large, slightly raised and rounded on the back, finely 
and subrugosely punctured, the punctuation, however, being somewhat variable, and with a small horn, 
which is longer and more slender in the female than in the male, but is much smaller in both sexes in 
proportion to the size of the insect than is usually the case in the genus; tegmina fuscous, hyaline 
towards the apex, sometimes with the anterior third only hyaline; legs entirely ferruginous or fusco- 
testaceous ; underside pitchy. 
3. Long. 9 millim.; ab humeris ad apicem cornus 3 millim.; lat. int. hum. 3 millim. 
@. Long. 10 millim. ; ab humeris ad apicem cornus 4 millim.; lat. int. hum. 34 millim. 
Hab. Paxama, Bugaba, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
The specimens from the Volcan de Chiriqui are slightly different from the others in 
punctuation and in the colour of the tegmina, but all appear to belong to the same 
species. A. pinguis appears to be allied to A. tenuicornis from the Amazons Valley. 
There is a single female specimen from Temax, Yucatan (Gawmer), in our collection, 
which is allied to this species, but differs in one or two points, being more finely punc- 
tured, with the central carina of the horn more marked, &c.; it is not quite perfect 
and it could not well be described as new on this one example. 
A specimen from Bugaba is figured.
