it scarcely reaches one-fourth ; the series consists of nine costal, one apical (inverted), and six or seven 
terminal streaks, of which two below the apex and one at the tornus are very small, the upper ones being 
at the end of a series of larger spots following the line of the cell to the base; two other seriés occur 
along the fold and dorsum respectively, the intermediate space beyond the middle containing other spots, 
irregular in number and distribution, Hep. al, 29mm. Hindwings reddish orange, irregularly spotted 
throughout with purplish fuscous, the spots toward the base and dorsum larger than the others; cilia 
blackish, terminal line yellowish, interrupted by the dark marginal spots. Abdomen purplish fuscous, 
with five pale yellow transverse bands, Legs dark purplish fuscous. |

POLYORTHA Den. 
Type: Polyortha niveipunctata Dgn. (Dgn. 1905), 
PotyortHa Dgn. Ann. Soc. Ent. Belg. 49 85-6 (1905) ; Frnld. Gn. Tortr. 48, 63 (1908). 
Antennae about 4, simple. Palpi projecting at least twice the length of the head beyond it; hirsute, with 
long hair-like seales projecting beyond the base of the somewhat hirsute, porrected, terminal joint. 
Head somewhat roughly clothed. Thorax with moderate posterior crest. Forewings elongate, ovate, 
costa convex throughout, with groups of rough projecting scales; apex obtuse or somewhat angular, 
termen oblique, sometimes sinuate, with patches of raised scales: newration 12 veins ; 7-8 sometimes 
closely approximate, 7 to costa; 3 from near end of cell; 4-5 approximate, connate, or stalked. 
Hindwings 1; termen slightly sinuate; apex obtuse: neuration 8 veins; 3-4 stalked (or connate), 
5 remote, nearly parallel to 4; 6-7 closely approximate toward base, or short-stalked. Abdomen 
moderate. Legs: hind tibiae nearly smooth. 
This genus is closely allied to Oxygrapha Hb., which it greatly resembles in 
general appearance, and with which it agrees in having FW: 7 to costa, but differs 
in its longer palpi, and in HW: 5 being remote from 8-4, which are stalked in the 
Central American species. It is possible that several of the forms here described as 
species may ultimately prove varieties of some polymorphic species—having regard 
to the variation exhibited in some of the European species of Oxygrapha. 
1. Polyortha nigriguttata, sp.n. (Tab. VIII. fig. 10.) 
Antennae whitish at the base, speckled with grey, cinereous beyond. Pulpi very long, reaching four times 
the length of the head beyond it, the terminal joint about half the length of the median; white, speckled 
with greyish brown. Head white, speckled with greyish brown. Thorax white, with a large black 
spot posteriorly, Forewings with the costa evenly and considerably arched, ciliate throughout, the 
cilia beyond the middle notched; white, speckled with light brown, and spotted with black; the black 
spots arranged as follows:—one on the middle of the costa, a second beneath and slightly before it ; 
straight below the second is a small one above the fold, preceded by a group of three, nearer to the base, 
two below and one above the fold; a large one, beyond the middle of the dorsum, preceded by two 
smaller ones, nearer to the base, scarcely touching the dorsum ; at the tornus is a reduplicated black 
spot, and above it a similar double spot opposite the middle of the termen, preceded by a single one at 
the outer end of the cell; the brown sprinkling is more noticeable along the costa, where it has a 
tendency to take the form of slender, angulated or cireular lines ; cilia white, speckled with grey near 
their base; underside greyish brown, the cilia distinctly whitish throughout. wp. al. 30 mm. 
Hindwings greyish brown; cilia slightly paler, with a dark shade along their base, tending to whitish 
at the apex; underside greyish brown. Abdomen greyish brown. Legs pale cinereous.
