16 HEMIPTERA-HETEROPTERA. 
with fuscous; antenne with the apical and the two basal joints black and the third joint testaceous ; the 
legs testaceous, the knees and tarsi more or less infuscate ; the hood, margins, and carine of the pro- 
notum with very fine scattered hairs, the costal margin and median nervure of the elytra very minutely 
denticulate, and also with very fine hairs. Head with five rather short slender spines; antenne long 
and slender, joint 1 three times as long as 2, 2 very short, 4 much longer than 1. Pronotum with the 
membranous margins moderately wide, recurved, converging anteriorly, with two rows of areole ; hood 
rather short, broad-oval, considerably raised; the long median carina strongly foliaceous, with a single 
row of transverse areola, the outer carine moderately foliaceous. Elytra rather elongate, widening 
from the base, the costal margin hollowed at the middle, the apex rounded ; discoidal area raised, short, 
rather widely reticulated; subcostal area almost vertical, biseriate behind, uniseriate in front; costal 
area with two rows of areole, those of the inner row becoming quite small towards the base, the others, 
like those in the apical half of the sutural area, very large. 
Length 24, breadth 13 millim. 
Hab. Panama, Bugaba (Champion). 
Five specimens. Differs from all the other allied forms in the very wide reticula- 
tion of the elytra, the areole being comparatively few in number, this character (and 
the black second joint of the antennz) separating it at once from L. gracilenta, 
L. angustata, &c. 
7. Leptostyla elata, n. sp. (Tab. I. figg. 21; 21a, profile; 210, part of 
the body beneath.) 
Moderately elongate, broad ; body black, the disc of the pronotum sometimes brown ; the integument whitish 
or pale testaceous, the dilated portions of the pronotum and the elytra hyaline; the elytra usually 
with three or four of the transverse nervures before the middle, an oblique curved stripe extending along 
each side of the median vein from the end of the subcostal area to the apex (in some specimens extending 
forwards along the sutural area), and two spots on the outer part of the discoidal area, fuscous or black ; 
the antenne testaceous, with the basal joint to near the tip, and the apical joint entirely, black, the second 
joint sometimes infuscate ; the legs testaceous, with the apical joint of the tarsi black. Head with three 
long slender spines—one median and two lateral; antenne long and slender, joint 1 about three and 
one-half times the length of 2, 2 very short, 1 and 4 subequal in length. Pronotum with the mem- 
branous margins very broadly subangularly dilated, recurved, rather closely reticulated, there being 
about five rows of areole at the middle; hood large, strongly raised, oboval; the three carine slightly 
foliaceous, the interspaces punctured, reticulated behind. LElytra rapidly and arcuately widening from 
the base and then parallel to near the tip, which is broadly rounded; discoidal area not half the length 
of the elytra, somewhat piritorm, closely reticulated ; subcostal area rather wide, triseriate, the areole 
small and rounded; costal area with four rows of areolee, decreasing to three at the base, the areole, and 
those of the sutural area also, moderately large. Rostrum reaching the meso-metasternal suture. 
Length 34-4, breadth 2-24 millim. 
Hab. Mexico, Amula in Guerrero (H. H. Smith); Guatemata, San Isidro, Pantaleon, 
Capetillo, San Gerénimo (Champion). 
Found in numbers in Guatemala, singly in Mexico. This insect is very like 
Gargaphia nigrinervis in general shape ; but differs from it in having the rostral groove 
uninterrupted by a transverse carina between the meso- and metasternum, the basal 
joint of the antenne longer, &c. Following Stal’s arrangement, the species would 
have to be placed in his third section of the genus, near L. furcata. A specimen 
from San Gerénimo is figured.
