304 HEMIPTERA-HETEROPTERA. 
of the corium below the base pale, and the nervures of the membrane in part, fuscous or dilute fuscous ; 
the corium in fresh specimens with two posteriorly confluent crimson streaks at the apex, the nervures 
usually pale; the pleura, a row of spots along the sides of the connexivum, a narrow vitta down each 
side of the venter, the apex of the second antennal joint, the apices of all the tibie, and a narrow annulus. 
before the apices of the hind femora, black or fuscous, the tibie usually with at least one darker ring 
near the base and the anterior and intermediate femora with a similar ring near the apex. Head shorter 
than the pronotum, the eyes small, prominent, and coarsely faceted ; antenne very slender, as long as 
the body, joints 2-4 nearly equal in length, 1 shorter than 2 and about as long as the head. Pronotum 
about as broad as long, the posterior lobe and the collar rugosely punctate, the basal portion of the 
anterior lobe almost smooth. Elytra constricted at the sides below the base, extending some distance 
beyond the abdomen, and in the male almost covering it externally. Abdomen rounded at the sides in 
the female, more parallel-sided in the male, the connexivum moderately wide. Anterior and intermediate 
legs with the femora beneath, and the tibie within, finely denticulate. 
Length 63-8, breadth 14-23 millim. (¢ 9.) 
Hab. Mexico, Atoyac and Teapa (H. H. Smith); Guatemaa, Batheu in Vera Paz, 
Las Mercedes, Cerro Zunil, San Isidro, Zapote (Champion); Panama, Volcan de 
Chiriqui (Champion). 
Numerous examples, all macropterous. [Easily distinguishable from the other 
Central-American species by the rugose posterior lobe of the pronotum and the laterally 
constricted elytra. The coloration of the elytra is somewhat variable and difficult to 
describe, and it is only in fresh examples that the crimson streaks are visible at the 
apex of the corium. The long scattered hairs on the legs are very fine. The membrane 
usually has a patch behind the apex of the corium and the tip pale. A Chiriqui 
specimen is figured.

Brachypterous form.—Elytra very short, barely twice the length of the scutellum, the apices rounded and 
divaricate. (¢ 9.) (Fig. 32.) 
Hab. Mexico, Teapa (7. H. Smith). 
A small narrow species, flavo-testaceous in colour, with the pronotum, scutellum, 
clavus, corium, and membrane streaked with fuscous or brownish; the apex of the 
second antennal joint and the apices of the tibiz blackish, the rest of the legs speckled 
and annulated with fuscous, the femora and tibie with scattered strong sete arising 
from the fuscous dots; the pronotum with the posterior lobe and the collar closely, 
finely punctate. In the brachypterous form the elytra and the upper surface of the 
abdomen are streaked with fuscous or blackish. The abdomen is closely pubescent, 
above and beneath. Six macropterous specimens were found at Bugaba and a pair of 
brachypterous ones at Teapa. The latter agree perfectly with the others in their 
general structure. JV. signatus belongs to the subgenus Hoplistoscelis, Reut.
