LEPTOSTYLA.—LEPTOPHARSA. 21 
fourth times as long as 4. Pronotum with the membranous margins moderately wide, recurved, 
converging anteriorly, with two rows of areol~#; hood short, considerably raised; the three caring feebly 
foliaceous, the interspaces closely punctured. LElytra moderately long, oval, constricted at the middle, 
rounded at the tip; discoidal and subcostal areas closely reticulated, the discoidal area not or scarcely 
reaching the middle; costal area moderately wide, with two rows of areole; sutural area with the' 
areoles very unequal in size, one of the inner ones being larger than the rest. 
Length 2-23, breadth 1-1) millim. , 
Hab. Guatemata, Pantaleon (Champion); Panama, Bugaba (Champion). 
One specimen from each locality. This pretty little species differs from all the other 
Central- American members of the genus in the oval, medially constricted elytra and 
comparatively short antenne. The Panama specimen ( @ ) is larger than the one from 
Guatemala, and has the elytra longer, with the subcostal area more widely reticulated. 
The Guatemalan specimen is figured. 
LEPTOPHARSA. 
Leptopharsa, Stal, Enum. Hemipt. iii. pp. 122, 126 (1873). 
This genus, based upon two Tropical-American species, seems only to differ from 
Leptostyla in the very small transverse pronotal hood, in connection with the closer 
subequal reticulation of the sutural and costal areas of the elytra, the costal area 
having two rows of areole, increasing to three at the middle; the basal joint of the 
antenne not more than twice the length of the second. The single species from 
Panama now added has the pronotum unicarinate only, and the rather stout spines on 
the head biunt at the tip. 
1. Leptopharsa unicarinata, n. sp. (Tab. II. figg. 7; 7 a, profile.) 
Moderately elongate, rather narrow; body black, the integument testaceous and subhyaline; the legs and 
antenne testaceous (the apical joint of the latter broken off). Head with three rather stout, blunt, 
porrect spines—two lateral, behind, and a frontal one, placed more forwards ; antenne long and slender, 
joint 1 about twice aslongas2. Pronotum narrowed and constricted in front ; the membranous margins 
narrow and of nearly the same width throughout, forming a prominent obtuse angle behind, with two 
rows of very small areole, diminishing to one in front; hood small, short, transverse as viewed from 
above, projecting a little in front; disc densely punctured, with a single feebly raised median carina ; 
posterior triangular portion membranous. Elytra long, arcuately widened from the base and broadly 
rounded at the tip; discoidal area narrow, not nearly reaching the middle, scarcely wider than the 
subcostal area, both closely reticulated; costal and sutural areas somewhat closely and subequally 
reticulated, the costal area with three rows of areole at the middle, diminishing to two at the base. 
Length 3, breadth 12 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example. Differs from Z. elegantula, Stal, from Bogota (the type of which is 
before me), in the unicarinate pronotum, the membranous margins of which follow 
the outline of the pronotum itself, and appear narrowed and constricted in front; also 
in the shorter discoidal area, rather wider reticulation, and trispinous head.
