which should probably be merged in it. Chiefly North American, though one Central American species is added 
because scarcely more than a race of one of the former. 
Ch. phyllinaria Zell. (= vertaria Pears.) is a small species of a pale green colour, finely irrorated with 
white, the lines distinct, much more sinuous than in chloroleucaria. Face brownish red. Zeller’s type was 
from Texas, Pearsall’s from Arizona and the species is also known from New Mexico. 
Ch. zelleraria Pack. (= phyllinaria Hulst, nee Zell.) (8 b). Very similar to the preceding but with green 
face and less irrorated green ground-colour. Range similar, the type from Texas. 
Ch. curvifera Prout (8 b). Face abraded in the unique type, but with enough scales left to indicate 
that it has been green; otherwise I should suppose it to be identical with a form (referred by Pearsall to 
phyllinaria = vertaria) in which the postmedian of the forewing “makes a single broad outward sweep.” Collect¬ 
ed by R. E. Kunze at Phoenix, Arizona, in September 1907, together with phyllinaria. I think the same 
species occurs in Mexico. 
Ch. appellaria Pears. “Expanse 13 mm. Palpi short. Front dull red-brown. All wings have a ground- 
colour of creamy or pale clay-yellow scales; over this is spread a thin covering of pink scales, leaving the cross 
lines and a narrow costal band of the ground-colour; these lines cross all wings, as in chloroleucaria, though 
more slender and slightly waved; no discal dots.” Beneath paler clay-yellowish, forewing subcostally and 
near base tinged with pink. Arizona: Yuma County. — rubromediaria Cass. & Swett, equally unknown to me, 
must surely be a form of appellaria, perhaps synonymous. The description fits exactly, except that the fore¬ 
wing has the median area more reddened than the rest of the wing and an indistinct discal dot sometimes 
present. Utah: Eureka, a very long series. “A study of the genitalia shows good characters” as compared 
with chloroleucaria, but these are not published. I surmise that the authors overlooked appellaria. 
Ch. chloroleucaria Guen. ( = rectilinea Zell.) (8 b). On an average less small than phyllinaria, of which 
Zeller supposed it a form, and readily distinguished by the straight postmedian line. Face rather bright 
orange-reddish. Palpus rather long, especially in the $. Common from Canada to California and Mexico. 
Larva with head strongly bifid, similar but smaller projections on prothorax, body much attenuated anteriorly, 
thicker behind; green, with head partly brown, a variable red-brown dorsal stripe often present, either continuous 
or interrupted. On various flowers, as Eupatorium, Achillea, Helianthus, Aster, Leucanthemum, etc. Pupa 
whitish, with a black dorsal stripe and sometimes much black or dark maculation; in a slight cocoon. Ap¬ 
parently dou ble -brooded. 
Ch. densaria Walk. (= deprivata Walk., indiscriminata Walk., ? desolataria H.-Sch.) is very close to 
chloroleucaria and I had supposed it synonymous, but I find the antennal pectinations of the <$ are a little 
longer and continued to nearer the tip, the $ hindtibial hair-pencil perhaps a little stronger; postmedian line, 
on the whole, perhaps not quite so straight. Florida and ? Cuba; I have no Cuban material before me but 
believe desolataria represents this same species. The type of indiscrimata is a $; I therefore give precedence to 
the name densaria, published at the same date. 
Ch. triangularis Prout (8 c). Forewing somewhat more triangular than in chloroleucaria , hindwing with 
termen slightly more sinuous. Colour more olive green, postmedian line rather less straight. Mendocino County, 
California. 
Ch. inveterascaria Swett (8 c). “20 mm. Pectinations much shorter and stouter than in chloroleucaria. 
Forewing long, rather pointed, hindwing rounded; colour olive-green, extradiscal line whitish, on forewing 
regular, with a deep indentation at vein 2 and bent back at an angle on costa, on hindwing rather more 
rounded than in chloroleucaria. Seems nearest volantaria, extradiscal line not rounded outwardly but bent 
at an angle at costa. Tucson, Arizona, 1 d 1 .” The species from Palmerlee, Arizona, which we figure here as 
probable inveterascaria, is more robust than volantaria and with rounded, not bent hindwing. 
Ch. viridipallens Hulst, of which the type is a faded <$ from Colorado, is very similar to volantaria, but 
a little larger, and the hindwing seems paler and unmarked. Its supposed $ allotype from Arizona, is in any 
case a $ of volantaria , and it is not unlikely that the latter may have to sink as a synonym or race of viridipallens. 
Ch. volantaria Pears. (8 c). Closely similar to rather small and weakly-marked specimens of maso- 
naria, but with the hindwing less strongly angled at the 3rd radial. Abdomen scarcely mixed with brown 
above. Arizona. 
Ch. masonaria Schaus. Variable. The small, typical form (17 mm) from Jalapa, Mexico, differs very 
little from volantaria except in the brown dorsal markings of the abdomen. Even in shape it seems somewhat 
less extreme than the larger boldly-marked forms which are prevalent in Costa Rica. hyperalla form. nov. 
(8 c). Large, notably in the 9$, which have an average expanse of about 30 mm. Abdominal maculation reddish 
anteriorly, strongly fuscous posteriorly. Forewing usually with indications of a dark terminal line, interrupted
