Species description by W. L. Distant:

Head, pronotum, and mesonotum greenish. Head with the frontal marginal angles, a transverse streak on lateral margins, inner margin of eyes, and area of the ocelli black; ocelli red. Mesonotum with a central longitudinal suboblong spot, rounded posteriorly and angulated anteriorly, on each side of this a short oblique streak behind eyes, and a D-shaped spot near each lateral margin black. Mesonotum with four large, central, and somewhat irregular black-bordered obconical spots, a black spot on each lateral margin, and two small spots of the same colour in front of the basal cruciform elevation. Abdomen above dull testaceous, with the basal angles and anal appendage greenish, somewhat thickly clothed with white pile. Body beneath greenish; transverse striae to face, bases and apices of coxse, apex of rostrum, segmental incisures, and inner margins of anal appendage black. Legs greenish, apices of femora black, apices of tibiae and tarsi dull testaceous, tarsal claws black. Tegmina pale hyaline. Neuration of basal half greenish, remainder fuscous ; base of first ulnar area, transverse vein at base of second ulnar area, a central spot on the longitudinal vein enclosing third ulnar area, and transverse vein at base of eighth apical area, and claval margin black ; a prominent white opaque spot at base of first ulnar area. Anastomoses, and a submarginal row of spots situated on veins, pale fuscous. Wings pale hyaline; veins fuscous, with some of the discal ones greenish.

The face is globose, strongly and transversely striate, with a central longitudinal sulcation; rostrum reaching the posterior coxae; head small, with the eyes very globose, and much narrower than base of pronotum.

Long. 17 millim., exp. of tegm. 66 millim.

Area of the ocelli, a central fascia to pronotum (which is ampliated and produced on each side at anterior and posterior margins), some obscure and irregular spots on mesonotum with cruciform elevation at base, and abdomen above fuscous. Body beneath much paler and very densely pilose; head, sternum, and opercula ashy grey; abdomen pale ochraceous. Tegmina pale hyaline; costal membrane, basal area, and claval base pale castaneous; veins pale fuscous. Wings pale hyaline ; veins and suffusion at abdominal area pale fuscous.

Head, including outer margin of eyes, broader than pronotum; face with a broad central longitudinal sulcation and somewhat faintly transversely striate; rostrum not quite reaching posterior coxae; opercula reaching base of second abdominal segment, narrowest at base, with the outer margins truncate, widened and rounded posteriorly, but not quite meeting inwardly.

Pacarina championi (Distant, 1881)
The image says Proarna championi but its newest name is Pacarina championi.

Species description by W. L. Distant:

Body above dull testaceous, somewhat sparingly pilose. Head with the frontal margin, a transverse fascia in front of eyes, and area of the ocelli black. Pronotum with two central longitudinal fasciae, two oblique striae on each side, and inner lateral margin black. Mesonotum with two large obconical basal spots, bordered on each side by a larger obconical fascia, and a small transverse fascia on disk, preceded by two small rounded spots, black. Abdomen above somewhat thickly covered with white pile, and with the basal segmental margins fuscous. Body beneath paler; anterior submarginal fascia to head, central fascia and transverse ridges to face, and apex of rostrum black. Legs unicolorous, apices of tibiae and tarsi testaceous.

Tegmina pale hyaline; veins ochraceous, darker towards apex; base and apex of first apical area, and transverse veins at base of second and third apical areas, broadly fuscous; base of first ulnar area thickened, opaque, and fuscous. Wings pale hyaline, veins ochraceous.

The face is globose, strongly transversely striated, but not sulcated longitudinally; and in width, it equals its distance from outer margin of eyes. The opercula are broad, not passing base of first abdominal segment, somewhat narrowed and almost meeting interiorly. (In the specimen figured the opercula are pale and unicolorous; in other specimens, they are inwardly and broadly margined with black.)

Long. 14 to 16 millim., exp. tegm. 45 to 52 millim.
