Long 1, Exp. 2 lines. Oblong-ovate, fusco-ferruginous, with whitish silky pile; 
paler beneath; abdomen brown; antennae and legs pale yellowish ; cuneus, 
membrane, and sutural appendage of hemelytra, glossy iridescent; wings yel¬ 
lowish-white, with faint ferruginous veins ; head equilateral triangular, front even; 
ocelli ruby-red, adjacent to the upper margin of the eyes; eyes rather small, 
with few facets, and some fine hairs interspersed; antennae half as long as the 
body ; 1 st joint little longer than broad ; 2 nd three times as long as the first, both 
pubescent; 3rd and 4th twice as long as the second, very slender and flexible, 
thinly beset with long hairs. Proboscis somewhat hairy, with the three segments of 
nearly equal length, the base more arched and free than usual, the last joint slender, 
not extending back beyond the fore coxae, between which it reposes; thorax tra¬ 
pezoid, gradually widened behind in continuation of the outline of the head, one- 
half shorter than its anterior breadth, the fore edge nearly straight, the sides 
slightly sinuated, the hind edge nearly straight, the hinder angles slightly rounded; 
scutellum triangular, broader than long, but the apex acuminate. Wings ample, ex¬ 
tending beyond the abdomen on all sides, and rather broader than the thorax; the fore 
pair with the exterior vein of the corium thick, dividing before one-third of its course 
into two branches, the exterior curved, approaching and then following the costal 
edge, the interior branch oblique, running to join the internal vein at the tip, and 
connected with it by a tranverse veinlet before that; veins of the clavus united 
before the tip, the inner edge dilated into a narrow triangular, membranous ap¬ 
pendage, superincumbent in repose. Cuneus separated from both corium and 
membrane, triangular, and nearly membranous itself, marked with two oblique 
impressed lines ; the anterior suture diaphanous, notched at the costa. Membrane 
ample, obliquely traversed by two veins, arising from the end of the clavus and its 
appendage respectively, connected about the middle by a transverse veinlet, and 
diverging a little as they approach the margin behind the apex. Lower wings with 
a deep narrow incision of the hinder edge, corresponding to the costal notch of the 
opposite hemelytrum when incumbent; a simple vein runs from the base to this 
incision, another originates from a thickened root, near the base of the wing, 
between this vein and the costal; from the latter, at about one-third of its 
course, a fainter vein springs, which soon parts into two branches, that reuniting 
enclose a small lanceolate areolet, and then runs towards the tip of the wing. Legs 
of moderate length; the fore femora especially rather thick; the posterior tibim 
armed with a few weak spines ; the fore pair merely pubescent, thickened at the 
tip, under which lies a very minute, narrow, membranous hollow (far less deve¬ 
loped than in Xylocoris ). Tarsi with the first joint very short; the second twice 
as long as the third ; the ungues as long as the latter, simple, acute, curved at the 
base; empodium very minute; anterior tarsi short. Abdomen brown, shining 
and naked above, pubescent beneath.
