STENOCYSTA.—AMBLYSTIRA. 29 
In the form of the antenne this genus approaches Megalocysta, but differs from it 
in the structure of the pronotum, elytra, &c. 
1. Stenocysta pilosa, n. sp. (Tab. II. figg. 18; 18a, profile; 18 d, antenna.) 
Moderately elongate, broad; opaque, fuscous, the small areole of the pronotal and elytral margins and of the 
pronotal hood hyaline; the elytra with a network of blackish lines on the nervures of the costal and 
sutura] areas, and the nervures of the interspaces testaceous, the discoidal and subcostal areas also marked 
with black; the antennee fuscous, with the third joint obscure ferruginous beyond the middle and the 
apical joint black; the surface thickly pilose, the pilosity extending to the legs, antenne, and elytral 
margins, the latter appearing closely ciliate. Pronotum with the angularly dilated margins greatly raised, 
converging forwards; hood strongly raised, obliquely truncate and slightly projecting in front; median 
carina angularly raised anteriorly, and continuous with the hood, with a few transverse areole, the outer 
carine slightly curved inwards in front and terminating in the inconspicuous transverse pronotal calli, 
the interspaces on the disc closely punctured ; the triangular posterior portion large and closely reticulated. 
Elytra with the areole of the discoidal and subcostal areas, and also those of the greater part of the 
sutural area, very small, those of the costal area being larger and more unequal in shape, the subcostal 
area quadriseriate, the costal area multiseriate ; discoidal area not raised, flat, well defined. 
Length 5, breadth 3 millim. (9.) 
Hab. Panama, Bugaba (Champion). 
One example. Viewed laterally, the pronotum of this curious insect has four 
prominent, angular, foliaceous elevations. The costal area or dilated margin of the 
elytra has a marmorate appearance, due to the coloration of the nervures. 
AMBLYSTIRA. 
Amblystira, Stal, Enum. Hemipt. iii. pp. 120, 129 (1873). 
The four Central-American species referred to this genus differ from the type, 
A. pallipes, Stal, from Rio Janeiro, in having the triangular posterior portion of the 
pronotum less obtuse at the tip, and the head without oblique interocular ridges 
(termed spines by Stal in his conspectus of the genera). The buccal lamine are short, 
the cavity formed by them being almost open in front. The rostrum about reaches 
the meso-metasternal suture. The intercoxal portions of the meso- and metasternum 
are very broad, the rostral groove thus being very wide beyond the anterior coxe. 
The antenne and legs are slender. The pronotum is faintly carinate at the sides and 
uni- or tricarinate on the disc, the median carina being sometimes strongly raised 
behind. The form of the costal area is variable, it being in one species (A. levifrons) 
confined to the apical portion of the elytra. The discoidal area is rather large in 
A, levifrons, smaller.in the other species. The wings nearly reach to the tip of the 
elytra. Our four representatives may be thus differentiated :-— 
Costal area extending to the base of the elytra; discoidal area rather short, flat. | 
Pronotum strongly convex, obsoletely carinate at the sides; costal area 
extending narrowly to the base. 
Pronotum shining, tricarinate; elytra with a rather large space beyond 
the middle, and a streak on the costa near the base, hyaline . . . fuscitarsis, n. sp.
