ACONOPHORA. 69 
i. Aconophora ferruginea, sp: n. (ab. V. figg. 16, 16a.) 
since, cit nigro, pronoto ferrugineo, fortiter densius punctato, cornu nigro vel nigro-piceo, hoc sat longo, 
apice nonnihil dilatato, humeris prominulis, lateribus ante apicem late sinuatis, apice ipso brevi; tegmi- 
nibus fuscis vel fusco-nigris ad apicem dilutioribus, sed vix pellucidis ; pedibus totis ferrugineis ; corpore . 
subtus plerumque ferrugineo. 
A small species, with the head black and the pronotum entirely ferruginous, strongly and closely punctured, 
the punctures on the sides being larger than those in front and towards the apex; the horn is rather long, 
pitchy, with the apex slightly dilated ; shoulders rather prominent; sides of the pronotum broadly sinuate 
before the apex, which is short and comparatively obtuse ; tegmina fuscous, lighter at the apex; legs 
entirely ferruginous; abdomen ferruginous, rather darker in the centre. 
Long. 8 millim.; ab humeris ad apicem cornus 34 millim. ; lat. int. hum. 23 millim. 
Hab. Mexico (coll. Signoret); Panama, Bugaba (Champion). 
Four specimens. This species is closely allied to A. prunitia, Butl. (=A. hastata, 
St4l), from which it may at once be known by its coarse punctuation and differently- 
shaped pronotal horn. The specimen in Signoret’s collection named A. nigru must be 
referred to A. ferruginea. | 
We figure a specimen from Bugaba. 
18. Aconophora disparicornis, sp.n. (Tab. V. figg. 17, 17 a, 2.) 
Quoad formam staturamque 4. ferruginece affinis, sed paullo latior et magis nitida, pronoto densius et subtilius 
punctato, fusco-testaceo, cornu maris brevissimo.

Femina : cornu pronoti modico, longiori et tenuiori. 
Of a fusco-testaceous colour, with the head, the tip of the pronotal horn, and the underside dark; pronotum 
closely and comparatively finely punctured, but in this point somewhat variable, with the shoulders 
somewhat prominent, and the horn very short in the male, slender and of moderate length in the female ; 
tegmina hyaline, darker towards the base ; legs testaceous or fusco-testaceous, with the femora, as a rule, 
more or less infuscate.

A male specimen is figured. 
19. Aconophora fusiformis, sp. n. (Tab. V. figg. 18, 18 a,¢; 19,2.) 
Elongata, nitida, brunnea, plus minusve fusiformis, capite infuscato ; pronoto sat fortiter punctato, cornu brevi 
recto obtuso, apice ultra apicem corporis producto supra viso brevi haud acuto; tegminibus hyalinis ad

Femina latior, minus fusiformis, pronoto pone cornu late testaceo ; pedibus fuscis, genibus rufis. 
Elongate, shining, male narrow and strongly fusiform, almost entirely brown, except at the sides of the 
metopidium, female broader, testaceous behind the horn for about half of its length ; pronotum slightly 
raised and rounded on the disc, strongly punctured, with a short straight horn, which is blunt if viewed 
from the side, but slightly tapers to the apex, and with the dorsal ridge very marked throughout ; tegmina
