196 HEMIPTERA-HETEROPTERA. 
also with a few sete; the head, pronotum, and scutellum almost smooth. Antenne moderately long, the 
two basal joints rather stout, the others very slender, joint 2 nearly twice as long as 1, 3 and 4 subequal 
in length, each much shorter than 2. Pronotum with the longitudinal median sulcus, as well as the 
transverse one, very deep, the sete on the anterior lobe arising from inconspicuous raised points, the 
posterior lobe feebly transversely rugose in the central depression, the thickened anterior angles rather 
prominent. Scutellum shortly and acutely produced at the apex. Corium with the discal cell obliquely 
and narrowly extended on to the inner basal portion of the membrane. 
Length 5-6, breadth 13-2 miilim. (¢ Q@.) 
Hab. Panama, Volcan de Chiriqui (Champion). 
Three specimens. Very like the Brazilian WM. plebeja, Stal * (the type, 2, of which 
is before me), but smoother and more shining, with longer sete on the body and legs, 
the head smaller and narrower, the general coloration much darker. 
ARADOMORPHA, n. gen. 
Head small, convex, cylindrical, grooved down the middle in front, the antero-lateral portions forming two 
stout, downwardly curved, anteriorly converging processes, these being as long as the unarmed, declivous, 
anteriorly widening antenniferous processes, which equal the eyes in length; the post-ocular portion 
short, rounded externally ; the ocelli placed near the eyes and very widely separated ; the eyes (viewed 
laterally) transverse, coarsely faceted, moderately large ; antenne short, inserted midway along the sides 
of the ante-ocular portion of the head, joints 1 and 2 stout, 3 and 4 slender, 1 very short, about one-fifth 
the length of 2, 2 nearly as long as 3 and 4 united, the latter subequal; rostrum short and stout, joint 2 
elongate, 3 short. Pronotum broad, transverse, emarginate in front and unemarginate behind, divided by 
a deep, sinuous, transverse sulcus into two lubes of nearly equal length, the lateral constriction deep; the 
anterior lobe narrower than the posterior lobe, with indications of four sinuous ridges, which impinge on 
the transverse groove. Scutellum triangular, the apex produced into a short, stout, horizontal, spiniform 
process. Elytra ample, reaching the apex of the abdomen; corium coriaceous; membrane largely 
developed, the inner basal cell narrow, the outer one much longer and broader and connected posteriorly 
with a large pentagonal cell, the inner nervure of the first cell continued downwards to beyond the apex 
of the corium. Abdomen( 3) with the connexivum broad and extending completely round the apex. Legs 
short and stout; anterior femora strongly, the intermediate femora moderately, incrassate, each armed 
with two rows of widely scattered, short spines beneath ; tibie with a short spine at the outer apical 
angle, the anterior and intermediate pairs denticulate within ; tarsi 2-jointed, the claws simple. Body 
robust, broad, obovate, flattened above. 
The single species referred to this genus has very much the facies of an Aradid; it 
is allied to Epirodera, Westw. (nec Signoret). It differs from the Acanthaspidine, as 
defined by Stal, in having all the tarsi 2-jointed. 
1. Aradomorpha crassipes, n. sp. (Tab. XII. figg. 8, 8a, 3.) 
3. Reddish-brown ; the head, except in front, and the tip of the scutellar process, blackish ; the membrane 
fuscous, with the base pale flavous, this colour extending on to the apical half of the clavus; the corium 
with the apical third obscurely ochreous, this portion separated from the rest by an oblique curved black 
line; the connexivum ochreous, with the base of each segment broadly banded with fuscous; the legs 
brownish-ochreous, the base of the femora and the intermediate and hind tibie darker; the body, corium, 
and two basal joints of the antenne sparsely, and the legs somewhat thickly, clothed with short, curled, 
decumbent, scale-like, ochreous hairs, the apical two joints of the antenne with finer hairs, the hairs on
