The two Central-American species referred to this genus differ from the typical 
forms, C. ‘columbica and C. capitata, Stal, from Colombia, in having the abdomen 
unarmed at the sides and the spines on the head reduced to small tubercles. All of 
them have long spines on the posterior lobe of the pronotum, a comparatively short, 
broad abdomen, and long elytra. C. seadens and C. spinosa (Fabr.), from Guiana, 
evidently do not belong here. 
1. Corcia ‘nigricornis, n. sp. (Tab. XVII. fig. 1, 2.) 
@. Elongate, rather broad, very sparsely pilose; reddish-ochreous fading to stramineous, beneath strami- 
neous; the head with a V-shaped mark in front, a cordiform spot surrounding the ocelli, and the 
upper part of the neck, the pronotum with an oblong mark or spot on the disc of the posterior lobe and a 
spot on the anterior lobe, the scutellum in the middle, and the clavus, black; the fourth and fifth 
connexival segments each with a broad transverse fascia above and beneath, and the ventral segments 1-5 
with a narrower fascia, black ; the membrane yellowish-hyaline, with the longitudinal median nervure slightly 
infuseate; the antenne black, with the apex of the first joint and the base of the second paler; the two 
“hinder femora with indications of a fuscous ring in one specimen. Head a little shorter than the pronotum, 
the usual spines before the eyes reduced to two small tubercles, the eyes moderately prominent; antennee 
long and slender, joint 1 more than three times the length of 2. Pronotum armed with two long spines 
on the disc of the posterior lobe and with a long spine at each of the lateral angles ; the anterior angles 
tuberculate, but not very prominent ; the posterior lobe with very fine punctures showing through from 
beneath. Elytra nearly twice as long as the abdomen. 
Length to the apex of the abdomen 11, to that of the elytra 15; breadth 3-4 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Two specimens. Very like C. colwmbica, Stal, from Colombia, the type of which is 
before me, but differing from it (and from C. capitata, Stal, also, which is probably a 
colour-variety of the same species) in the more elongate head, with the spines reduced 
to small tubercles, the less prominent anterior angles of the pronotum, and the unarmed 
sides of the abdomen. In C. columbica, moreover, each of the connexival segments is 
banded with black, and the main nervures of the membrane are nigro-fuscous. 
9. Corcia costaricensis, n. sp. (Tab. XVII. fig. 2, 3 *.) 
g. Elongate, rather broad, rufo-stramineous fading to stramineous, beneath paler, with the light-coloured 
portions of the ventral surface white; the head black above, except at the sides between and behind the 
eyes and a median line in front; the pronotum with a transverse anteriorly excised fascia before the base, 
including the four spines, another fascia on the posterior lobe in front, the two connected along the median 
line, and a third fascia on the anterior lobe before the apex, black ; the scutellum broadly black along the 
middle to near the apex; the elytra with a little more than the median third of the corium, the clavus, 
and the nervures of the membrane in great part, black; the fourth and fifth connexival segments each 
with a very broad transverse fascia above and beneath, and the ventral segments 1-5 with a narrower 
fascia, black; the antenne black, the third joint stramineous at the base, the first joint indistinctly 
* The elytra are incorrectly drawn in our figure: the neuration should be as in C. nigricornis. .
