PAOTA; HOLARCTIAS. By L. B. Prout. 
concoloraria. 
catagompha. 
gerocoma. 
fultaria. 
sarruncaria. 
sentinaria. 
califor niaria. 
pacificaria 
magnetaria. 
D. h i n cl wing beneath with the ochreous scaling continued nearly to 
the margins. 
S. concoloraria Dogn. (= concolaria Sharp ) (15 k). In addition to the sectional character, distinct in 
its rather large and dark colour and in the shape of the hindwing, which is weakly bent in the middle, not 
“evenly rounded” as Dyar’s key would indicate. Ecuador: Loja and Zamora; also a few scattered localities 
from Costa Rica to Peru. 
E. <$ hindwing strongly ventricose, the specialized scaling dark. 
S. catagompha Dyar (15k). Large and dark, the shape much more extreme than in concoloraria; under¬ 
side purple, with a broad area of long black lustrous scales on each wing to beyond the middle. Panama (type) 
and Gorgona Island. Forms (?) from French Guiana and Bahia await further elucidation. 
S. gerocoma Dyar is smaller (“15 mm” as against “19”), not so dark purplish, the lines broader and 
continuous, wavy. Underside, pale, with little purple tint, the specialized scaling brown, confined to the hind¬ 
wing and sharply delimited near its middle. St. Jean de Maroni, 1 J. 
34. Genus: Paota Hulst. 
Palpus moderate, slender. Antenna of $ with short pectinations, surmounted with fascicles of cilia. 
Hindtibia in the <$ much aborted, somewhat swollen, without spurs, the tarsus slender; in the $, according 
to Hulst, with 4 spurs. Forewing with areole double or simple (certainly variable). Hindwing with the costal 
diverging more gradually after its short anastomosis with the cell (about as in Haematopis), but certainly not 
“joined with cell nearly to middle”, as Hulst gives it; 2nd subcostal very shortly stalked. Affinities not yet 
detected, though it shows several characters in common with Prasinochrysa. Only two species known, or per¬ 
haps only one. 
P. fultaria Grote (15 k), the genotype, will be recognized at once from our figure. It seems to be rare 
and has only been recorded from Arizona, but I have seen an Orizaba $ which is absolutely typical. 
P. sarruncaria Schaus. Closely related to fultaria, of which I am inclined to treat it as a very extreme 
aberration or local race, with the dark markings reduced to a minimum; but Mr. Schaus considers it a species 
and I defer to his judgment. Lines identical, spots reduced, dark suffusions wanting. Oaxaca, Mexico, only 
the type known. 
35. Genus: Holarctias Prout. 
(See Vol. 4, p. 85; Suppl.-Vol. 4, p. 49).

Like Scopula except in the smaller eye and the more hairy vestiture, the long-projecting hair of the 
palpus generally a conspicuous feature. To some extent, however, it is probably connected with Scopula by 
intermediates. Typically, the $ has a “mappa” on the 8th sternite but lacks the “cerata” (rami) which are 
almost universal in Scopula , the socii are “broad, parallel-sided, longer than the distance between their tips, 
with long, coarse bristles”, the aedoeagus with one cornutus, but the whole organ “very characteristic in struc¬ 
ture, so that a longer description is needed” (Dr. J. Sterneck, in litt.). The typical group ( sentinaria sens, 
lat.), is liolarctic, the few others which are recognized belong chiefly to the mountains of the western United 
States. 
H. sentinaria Hbn.-Gey. (= spuriaria Christ., gracilior Btlr.) (15 k). Hindtibia of $ with 2 spurs. Fur¬ 
ther distinguished from the following by its brighter, more reddish colouring (almost as in Paota), more suf¬ 
fused proximal part of hindwing, etc. The type and that of spuriaria came from Labrador, Butler's gracilior 
from W. Canada. Variable, but no racial variation has been recognized in the New World; for the Palaearctic 
representatives reference should be made to Supp.-Vol. 4. 
H. californiaria Pack. (= californiata Pack.) (15 k). Hindtibia of the without spurs, though I have, 
among a short series from Oakland, one atavistic example with 2 short spurs on one tibia and 1 on the other. 
Possibly, according to Me Dunnough, only a colour form of magnetaria, but kept provisionally separate. 
“Snuff brown” (Packard; but considerably less dark than that of Ridgway) instead of reddish brown, other¬ 
wise very similar. California and Colorado. — ab. pacificaria Pack. According to its author this differs in its 
smaller size, more rounded apex of the forewing, less oblique termen, blacker postmedian line, etc. Said to 
be “common in California”. 
H„ magnetaria Guen. (= rubrolinearia Pack.) (14 a). Structure, so far as studied, identical with that 
of californiaria; from both it and sentinaria it has already been sufficiently differentiated. The locality for 
both the types (magnetaria and rubrolinearia) merely given as California.
