A monotypic Tropical-American genus, chiefly distinguishable by the short curved 
spines on the head, the convex, laterally spmed posterior lobe of the pronotum, the 
short, broad abdomen in both sexes, and the comparatively short legs.

We possess two males and three females of this species, all but one of which were 
found by myself in Chiriqui. They are very variable in colour, the three bluish-black 
lines on the posterior lobe of the pronotum being sometimes connected in front and 
behind, so as to enclose two large pale spots on the disc, and sometimes interrupted. 
In the darkest specimens the elytra have the base and a broad transverse fascia about 
the middle, the latter extending across the base of the membrane and the apex of the 
corium, and forwards along the costal and inner margins, but leaving a pale spot on 
the membrane, nigro-ceruleous. The femora and the basal joints of the antenne are 
very variable in colour. The elytra extend far beyond the abdomen in both sexes. 
The third joint of the antenne is not thickened in the males.

A Tropical-American genus including several very closely allied species. The two 
now added from Central America seem to be different from any of those described, one 
only of which is known to me. They are long and slender insects, with the sixth 
abdominal segment armed with a long spine on each side at the apex, the scutellum 
rounded behind, the post-scutellum produced into a short tooth, and the head and 
pronotum armed with long spines. The species differ sexually in the armature of the 
sides of the abdomen, the females having fewer lateral spines than the males. 
1. Debilia angustata, n. sp. (Tab. XVI. figg. 8, 8a, 3.) 
Elongate, narrow ; stramineous or testaceous, the elytra with an indistinct fascia beyond the middle, the apex 
of the corium, the clavus, and the adjoining basal portion of the corium, the nervures excepted, usually 
more or less fuscous in mature specimens; the apical portion of the corium in the middle, the knees, and 
the dorsal surface of the abdomen, sometimes partly stained with sanguineous. Head shorter than the 
pronotum, much narrowed behind, armed above with two long spines, the eyes large and prominent in 
the male, smaller in the female; antennz very elongate, joint 1 three times as long as 2, 3 slender in 
both sexes. Pronotum armed with two long spines on the disc of the posterior lobe towards the base and 
with a long outwardly directed spine at each of the lateral angles, the posterior lobe with two anteriorly
