44 HEMIPTERA-HETEROPTERA. 
EURYPHARSA. 
Eurypharsa, Stal, Enum. Hemipt. iii. pp. 122, 133 (1878). 
1. Eurypharsa fenestrata, n. sp. (Tab. III. figg. 17: 17 a, profile.) 
Brown, the membranous margins of the pronotum yellowish. Head with a slender frontal spine; antenne 
very shortly pilose, rather stout, moderately long, joints 1 and 2 equal, 3 nearly four times as long as 4, 
4 slightly longer than 1 and 2 united. Pronotum narrowing almost from the base, tricarinate, the carine 
abbreviated in front and meeting the small, compressed, acutely projecting hood ; the membranous margins 
moderately wide, raised, of uniform width, rounded behind and subangularly projecting in front, 
irregularly biseriate; the disc slightly shining, and very coarsely, closely punctate, reticulate behind; the 
posterior portion obtuse at the tip. Elytra nearly three times the width of the pronotum, truncate at the 
apex, the costa concave from about the basal third to near the tip, the latter rounded; discoidal area 
closely reticulated ; subcostal area very narrow, biseriate ; costal area extremely broad, very unequally 
reticulated, with a number of the areole near the base and a cluster of much larger areole on the inner 
part a little beyond the middle, as well as several along the costal margin and the whole of those along 
the apical margin, hyaline, the inner ones forming two large hyaline patches on each elytron. 
Length 53, breadth of the pronotum 13, of the elytra 44 millim. 
Hab. Panama, Bugaba (Champion). 
One specimen only of this extraordinary insect was obtained. 
It differs from the South-American £. nobilis (Guér.) (=circumdata, Blanch.), 
the type of the genus, in having the costal margin of the elytra concave from about 
the basal third (instead of rounded), and the costal area very unequally reticulated, the 
hyaline areole on the inner part forming two well-defined patches. 
ATHEAS. 
Rostrum short, not extending beyond the anterior coxe. Rostral groove uninterrupted, closed in front; the 
intercoxal portion of the metasternum cordate, the mesosternai lamin parallel or converging at the 
middle. Antenne slender, the two basal joints stouter, the first joint much longer than the second. 
Head short, with more or less acute antenniferous tubercles and an obtuse tubercle in the centre in front, 
the usual spines obsolete. Pronotum without hood, tricarinate, with expanded, thin, membranous, 
uniserlate margins, the triangular posterior portion sometimes abbreviated and obtuse at the tip. Elytra 
extending to far beyond the abdomen, oblong oval or subparallel, rounded at the tip; subcostal and 
discoidal areas very closely reticulated, the latter extending at least to the middle and rounded within ; 
costal area broad or moderately broad, hyaline, with two or three rows of areole. Wings nearly as long 
as the elytra. Orifice distinct. Legs slender. Form oblong, very depressed. 
The three small species referred to this genus are closely allied. The unusually 
short rostrum, the complete absence of the usual spines on the head, the simply 
carinate pronotum, and the prominence of the antenniferous tubercles, &c. separate 
them from Leptostyla and Leptodictya; and the thin, membranous margins of the 
pronotum and elytra, the acute antenniferous tubercles, &c., from Monanthia. The 
three species may be separated thus :— 
Antenniferous tubercles slender andacute . . . .. .. . . . . . flavipes, n. sp. 
Antenniferous tubercles shorter and stouter. 
Pronotum feebly tricarinate ; mesosternal lamine parallel . . . . . . fuscipes, n. sp. 
Pronotum sharply tricarinate; mesosternal lamine converging at the 
middle 2. 2... we ee ee ee nigricornis, D. Sp.
