by minute whitish dots at the veins; cell-spots indistinct, but on the hindwing fairly large; fringe dark-spotted 
opposite the veins. Costa Rica, the type from Juan Vinas in my collection, kindly presented by Mr W. 
Schatjs. But for the transitions in shape indicated above, this would certainly have been regarded as a Chloro- 
pteryx with unusually broad hindwing. 
31. Genus: Cliloropteryx Hulst. 
This genus, or perhaps better section of Chlorochlamys (see above) bears exactly the same relation 
thereto as does the Old-World Hemithea to Chlorissa. Except that the dorsal ornamentation of the abdomen, 
though generally pronounced, scarcely ever forms actual crests, it might be described as Hemithea with the 
antenna of the $, and occasionally even of the $, pectinate. The elongate hindwing, generally with rather 
sharp tail at the 3rd radial, separates it widely enough from typical Chlorochlamys, but in the first two species 
it is elongate without being tailed, so that they should perhaps be transferred to Chlorochlamys. The genotype 
belongs to the southern part of the Nearctic Region, but all the other species are Neotropical. 
Ch. paularia Mdschl. (= punctata Warr.) (8 c). A small and simple species, but not liable to be confused paularia. 
with any other. The white lines are always weak and are inclined to resolve themselves into mere vein-dots. 
Both the types were from Jamaica, but the species is also known from Cuba. 
Ch. acerces Front (8 c) is larger than the rest of the species and has the hindwing only quite weakly acerccs. 
bent at the 3rd radial. Glossy, with strong iridescent reflections. Besides the type $ from Petropolis, I know 
only the Rio $ here figured from the Joicey collection. 
Ch. chaga Dogn. Another rarity, unknown to me. 21 mm (tip to tip measurement). Habitus of Hemi- chaga. 
thea aestivaria Hb. White, very densely irrorated with green; cell-spots darker green; a sinuous green post¬ 
median line, punctuated with white dots on the veins, the forewing also with a similarly formed antemedian; 
costa of forewing yellowish, spotted with grey; a grey terminal line, interrupted with yellow at the veins; fringe 
dirty white, marked with yellow between the veins. Loja, Ecuador, 1 <$. 
Ch. diluta Dogn. (8 d) differs from chaga in the longer pectinations, more elongate hindwing, more diluta. 
whitish green colour, absence of cell-spots on forewing and of white vein-dots on the lines, etc. West Colombia. 
Ch. lechera Dogn. is whiter, only very finely marbled with pale green, the cell-spots indicated by an lechera. 
agglomeration of the green scaling; lines wanting; fringe concolorous; costa of forewing yellowish. Palpus 
of with 3rd joint moderately long. Likewise founded on a single $ from Loja. 
Ch. spnmosaria Dogn. A little larger than the two preceding (25 mm from tip to tip). Coloration as in spumosaria. 
lechera, but with the green lines present, on the forewing rather broad and nearly straight. Face and palpus 
olive-yellow* (in lechera pale). The antenna “pectinated to the tip” should distinguish it from opalaria (8 d), 
as well as the larger size. Loja, founded on 2 
Ch. opalaria Guen. (= albidata Warr., olvidaria Schaus) (8d). Antenna of with a rather long apical opalaria. 
part non-pectinate. Somewhat variable in the width and the degree of sinuosity of the green lines or bands and 
extremely variable in size, the smallest only about 13 mm from tip to tip, the largest $$ nearly 24 mm. 
Distributed almost everywhere from Mexico to Brazil, except on the W. coast. Guenee described it as an 
Iodis , with the locality given as “Central India?” It is therefore not surprising that a superficially similar 
Indian Iodis (subtractata Walk.) was misidentified for it until the publication of a good figure of it by Ober- 
thur. Very likely it was from Brazil, as is the specimen which we figure. 
Ch. viridicans Prout (8d). Extremely similar to the largest opalaria, but predominantly green, leaving viridicans. 
only dots and strigulae of white. Face and underside of costal margin of forewing more mixed with red. Distal 
margin of hindwing slightly excavated between the radials. Only known from Torne, Cauca Valley, Colombia. 
Ch. jalapata Dyar will perhaps prove a smaller form (18 mm as against 23—24) of viridicans, which jalapata. 
was published only 3 weeks earlier. “Thinly scaled, dull green over pale grey; lines greenish, a trace of white 
edge to the outer only; a discal dot on hindwing; outer margin produced. Uniformly clouded like albidata Warr., 
but uniformly greenish, not white.” Jalapa, 1 C- 
Ch. pacifica Prout (8 d) apparently replaces opalaria and viridicans in W. Peru. Hindwing rather less pacifica. 
produced; the pale green ground-colour not mixed with white; the lines more slender, not band-like. Callao 
(loc. typ.) and east of Lima. Also believed to have been taken at Valparaiso. 
Ch. glauciptera Hmpsn. (8 d). Smaller, more iridescent and of a more glaucous or greyish green than glauciptera. 
pacifica, the lines white, strongly wavy, only slightly and indefinitely bordered with green in the median area. 
Fore wing beneath without the reddish basal and anterior suffusions of the preceding group. Antennal pec-
