tinations of 3 rather long. Described from St. Vincent (type) and Grenada, but known also from others of 
the Lesser Antilles. 
Ch. languescens Warr. (8 c). Antennal pectinations of the 3 shorter. Otherwise not yet definitely 
differentiated from glauciptera, but perhaps rather greener in colour. Described from Dutch Guiana, but ap¬ 
parently extending as far as Costa Rica and Bolivia. Fresh material in the delicate species of this group is 
difficult to obtain. 
Ch. dealbata Warr. (8 d). Easily known by the uniform greyish olive forewing (only with white lines) 
and broad clear white median band of hindwing. Fringes spotted. Underside paler, with smoky apical patch 
on hindwing and sometimes a smaller one at tornus of forewing. S. E. Peru. A race ( ?) in Colombia, Venezuela 
and the Guianas. 
Ch. elemens Warr. (8 d) is rather variable and may probably be a race (or series of races not yet differen¬ 
tiated) of product aria, as some specimens, especially in Peru, are more or less intermediate. Typically it differs 
markedly in that the white parts are much more dusted over with green and the green-edged postmedian line 
as well developed on the hind- as on the forewing. Underside similar to upper. Ecuador; also in Central 
America, from Colombia to French Guiana and southward to Peru, if not to Bolivia. 
Ch. productaria H.-Sch. (8 e). Striking on account of the restriction of the green of the hindwing to 
a narrow terminal streak; the subterminal white of the fore wing also more extended than in most elemens. 
S. E. Brazil. 
Ch. tepperaria Hulst (8 e). Forewing rather broad, with distal margin gently curved and less strongly 
oblique than in the similar South American species that follow. Antenna of 3 with the pectinations rather 
long. North Carolina to Florida. 
Ch. longipalpis Warr. (8 e). Close to hernithearia, but of a rather greyer green and slightly intermediate 
in shape and markings between that species and tepperaria. It cannot be a race of liemithearia , as the $ palpus 
is longer 2nd joint elongate, 3rd about as long as 2nd. Venezuela (type), Colombia, the Guianas and Amazons; 
a race (?) in Sao Paulo together with the following. 
Ch. hernithearia Warr. (8e). Moderately bright green when fresh, but fading to dark olive-buff or 
yellowish; the white lines strongest on the veins, on both wings strongly excurved in the middle. Antennal 
pectinations of 3 rather short. Palpus of $ with 2nd joint moderate, 3rd joint less long than 2nd. S. E. Brazil. 
Ch. nordicaria Schaus (8e). Distinguishable from tepperaria and hernithearia by the presence of sharply 
blackish cell-dots and by the slightly more sinuous margin of the forewing and rather more sharply tailed 
hindwing. Pectinations intermediate between those of the species named. Variable in size, but generally 
quite small. Mexico and extending northward to Texas, southward to Costa Rica. 
Ch. munda Warr. (8e) with still stronger black cell-dots, is closer to hernithearia in size and shape. 
The type 3> from La Plata town, is badly faded and I know no other material from that region. It has, 
however, about the structure of the insect which we here figure (from French Guiana) on the assumption that 
it is a race of it: 3 with pectinations rather short, hindtibia very long, with pencil and moderate terminal 
process, tarsus strongly abbreviated. If this (which is known from Panama, Trinidad, Venezuela, the Guianas 
and Amazons) proves to be a recurrent black-spotted aberration of longipalpis , the true munda may prove 
to be a parallel aberration of hernithearia. 
Ch. punctilinea Dogn. (8 e) differs from hernithearia and longipalpis in the absence of the dark spots 
on abdomen and in having blotches on the underside as mentione dunder dealbata (8 d). Forewing, indeed, very much 
as in that species, but with the white lines expressed chiefly, or only, by dots on the veins; hindwing con- 
colorous. $ palpus about as in longipalpis. Pectinations of 3 moderate. Guianas, described from Maroni River. 
Also Colombia, Lower Amazon and E. Bolivia. 
Ch. fontana sp. n. (8e). Appreciably larger than punctilinea 3> the blotches of the underside less 
strong, more flesh-coloured, only becoming strongly darkened close to the fringes; a great part of the forewing 
beneath more or less suffused with flesh-colour, nearly as in the following species. Hindtibia with hair-pencil, 
but with the terminal process vestigial (in punctilinea rather long). Pectinations short, the longest only about 
twice the diameter of the shaft. Abdomen with dark spots, but generally weaker or more interrupted than 
those of hernithearia. Upper Amazon: Fonte Boa, May and June 1906 (S. M. Klages), 7 33 hi Mus. Tring. 
A $ from the same source, August 1906, which probably belongs with them but was misidentified by Warren 
(Nov. Zool., Vol. 16, p. 76) as subrufe-scens, is rather larger, the 3rd joint of the palpus unusually short for 
a Chloropteryx, the hindlegs unfortunately lost, the abdomen discoloured. 
Ch. subrubens sp. n. (8 f), which has also been mistaken for snbrufescens, has about the size and 
general aspect of fontana, though of a deeper grey-green and with the abdominal spots stronger. Hindtibia
