20 HEMIPTERA-HETEROPTERA. 
areole at the middle, diminishing to two at the base; the areole in the apical half of the sutural area 
very unequal in size, two of the inner ones being very large. 
Length 34, breadth 14 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 4000 feet (Champion). 
Twelve specimens. Not unlike the North-American L. oblonga; but without 
lateral spines on the head, the elytra broader and with more numerous areole in the 
costal area, the discoidal area much shorter. 
15. Leptostyla furculata, n. sp. (Tab. II. figg.5*; 54a, profile; 5, part of 
the body beneath.) 
Moderately elongate, rather broad ; body black, the integument whitish or pale testaceous and partly hyaline ; 
the elytra with the apex broadly, the large areole excepted, and the space between the costal area and 
the inner margin thence to the base, and the nervures of the pronotal hood, smoky-black or fuscous ; the 
antenne testaceous, with the apical joint, except at the base, fuscous or black; the legs testaceous. 
Head with two short slender frontal spines, approximating at the tip; antenne long and slender, joint 1 
scarcely more than twice as long as 2, 2 very short, 4 nearly twice as long as 1. Pronotum with the 
membranous margins moderately wide, recurved, converging anteriorly, with two or three rows of 
areolz ; hood short, oval, considerably raised; the three carine feebly foliaceous, the interspaces closely 
punctured. Elytra moderately long, arcuately widened from the base, rounded at the tip, the costal 
margin slightly hollowed at the middle; discoidal area rather short, not nearly reaching the middle, 
subfusiform, closely reticulated; subcostal area nearly as wide as the discoidal, closely reticulated ; 
costal area with three or four rows of areole at the middle and two or three at the base; the areole in 
the apical half of the sutural area very unequal in size, two of the inner ones being very large and 
pentagonal. 
Length 3-34, breadth 13 millim. 
Hab. Guatemaia, Senahu in Vera Paz, El Tumbador, Cerro Zunil (Champion) ; 
PanaMa, Bugaba (Champion). 
Found in plenty at Bugaba, rarely elsewhere. Very like Z. divisa, but easily 
separated from it by the entirely pale basal joint of the antenne; the apex of the 
elytra, too, is more clouded with fuscous, the larger areole excepted. The single 
specimen from Senahu has the apex of the elytra clearer than usual. 
L. furcata, Stal, from Rio Janeiro, the type of which is before me, is also ami allied 
form ; but it has more elongate and less parallel elytra, with the oblique fuscous fascia 
more distant from the apex, and the basal joint of the antenne much more elongate. 
A specimen from Bugaba is figured. 
16. Leptostyla constricta, n. sp. (Tab. II. figg. 6 *; 6a, profile.) 
Moderately elongate, narrow, narrowed behind ; body black, the pronotum with the hood and the membranous 
margins whitish, and the carine and the tip of the triangular portion pale testaceous; the elytra 
testaceous, with a rather broad transverse fascia on the costal area before the middle, and the apex and 
sutural area, one or more of the central areole excepted, fuscous, the rest of the costal area whitish and 
hyaline, the subcostal area bordered with black externally; the antenne with joints 1 and 2 obscure 
testaceous, 3 flavous, and 4 black; the legs entirely flavous. Head with two short converging spines in 
front ; antenne slender, comparatively short, joint 1 barely twice as long as 2, 3 about two and one- 
* Left elytron incorrectly placed uppermost by our artist.
