26 HEMIPTERA-HETEROPTERA. 
One example only of this remarkable species has been obtained. It is much 
broader and more pilose than the type of the genus, L. steind, Stal, from Brazil (the 
type of which is before me), and has the discoidal area of the elytra very much more 
tumid, the areole of the costal area more numerous, the pronotal hood very small 
and transverse, the basal joint of the antenne more elongate, &c. 
2. Leptobyrsa translucida, n. sp. (Tab. II. figg. 14; 14 a, profile.) 
Moderately broad ; ferrugineo-testaceous, the margins of the pronotum and the elytra hyaline; the median 
carina of the pronotum in the centre and an indistinct transverse fascia on the elytra a little below the 
base dilute fuscous, the nervures at these places black; the legs and antenne testaceous, the latter with 
the basal joint somewhat ferruginous. Head with two slender converging frontal spines; antenne 
long and slender, apparently glabrous, joint 1 about three times as long as 2, 2 very short, 4 nearly 
as long as 1. Pronotum with the membranous margins moderately wide, somewhat flattened, arcuate 
in front and slightly rounded externally, with large areole—two rows in front and one behind ; hood 
considerably raised, small, angularly projecting in front; median carina foliaceous and continuous with 
the hood, the outer carine very feebly raised, the interspaces shining and closely punctured; the 
posterior triangular portion greatly abbreviated. Elytra broadly rounded at the base as well as at the 
apex; Giscoidal area rather small, angularly raised, open behind, and rather widely reticulated; 
subcostal area subvertical, triseriate; costal and sutural areas widely and subequally reticulated, except 
towards the base, the costal area with above five rows of areole at the middle, decreasing to three at the 
base, the costal margin very minutely denticulate in its basal third. 
Length 3, breadth 23 millim. 
Hab. Guatema.a, San Gerénimo (Champion). 
One example. Smaller than L. steini, and glabrous, the elytra not sinuate at the base, 
the outer carine of the pronotum much less prominent, the discoidal area of the elytra 
angularly raised, &c. The frontal spines are broken. The insect is apterous. 
8. Leptobyrsa plicata, n. sp. (‘Tab. II. fig. 15.) 
Moderately broad ; testaceous, the margins of the pronotum and the elytra hyaline or pale testaceo-hyaline ; 
the elytra with two more or less distinct transverse fascize (one before and one beyond the middle), the 
base, and a spot near the apex, fuscous ; the entire margin of the elytra, and the margin of the pronotum 
in front, set with long bristly hairs, the elyiral nervures set with shorter hairs; the antenne with long 
fine projecting hairs, the legs sparsely pilose. Head with three slender frontal spines; antenne very 
slender, moderately long, joint 1 nearly three times as long as 2, 2 very short, 4 about twice as long 
as 1,3 not very much longer than 4. Pronotum with the membranous margins broadly and arcuately 
produced in front, abruptly constricted at the middle and very narrow and parallel thence to the base; 
hood very small, transverse, not raised; median carina feebly raised, the outer carine abbreviated and - 
not very distinct, the interspaces dull and closely, finely punctate. LHlytra very broad and somewhat 
ear-shaped, deeply sinuate in front and broadly rounded at the tip; discoidal area feebly raised, rather 
short, somewhat piriform, closely reticulated ; subcostal area sloping and nearly as wide as the discoidal, 
quadriseriate ; costal and sutural areas somewhat closely and subequally reticulated, the costal area 
transversely creased and with five to six rows of areole in the basal half; the main median nervure 
forming the outer limit of the subcostal area and only moderately sinuous. 
Length 3-34, breadth 2-23 millim. 
Hab. Panama, Bugaba and Pefia Blanca (Champion). 
Six specimens of this peculiar species were obtained. In the shape of the elytra 
it resembles L. latipennis and in that of the pronctum L. nigriceps, &c.
