C. chalcotoxa Dyar (44 k) is similar to acantha, but the subterminal golden spotted band is absent 
or indicated at most by one or two very small golden spots at the apex. Mexico (Teliuacan). 
C. acema Drc. (44 k) is smaller than the preceding species, otherwise very similar; the golden oblique 
band below the cell to the anal angle is much broader and of a quadrangular shape, in chalcotoxa narrow and 
of an elliptic rounded shape; the reniform macula is somewhat more distinctly prominent, above and below 
centred with a small golden spot. Mexico (Guerrero). 
C. dysnoa Dyar (44 k) has very broad, deep bronze brown forewings without golden spots, with a 
somewhat more produced apex and a slight excision below it; the fine transverse lines are somewhat darker, 
the reniform macula is an indistinct small darker spot. Hindwing dark brown. — ab. biforis ab. nov. (441) has 
the ring-macula and the lower end of the reniform macula centred with silvery white round spots. Mexico. 
C. chalcocraspedon Dyar (441) is another species very different from the others, with purple brown 
forewings, the basal and marginal areas being metallic bronze-coloured, with fine darker transverse lines, the 
maculae indicated by small bronze spots. Hindwing brownish-grey with a lighter postmedian band. Mexico 
(Zacualpan). 
C. koebelei Riley (441) is unmistakable owing to the silvery white forewing with 3 reddish-yellow 
transverse lines, the postmedian line being on the discal fold connected with the subterminal line which is 
removed far towards the margin; the space behind the latter line is tinted yellowish. Hindwing light brown. 
Known from Kansas and California. 
153. Genus: Itolua Dyar. 
On the whole corresponding with Chalcopasta, but the frontal appendage exhibits instead of the central 
projection a vertical fillet in the middle, and the raised margin is only below and laterally present, above the 
projection is not margined. Only 1 species: 
R. monetifera Dyar (44 1) has fox-coloured forewings with dark veins and 2 large silvery spots, a smaller 
obliquely elliptic one in the cell and a much larger, more triangular one behind it, which may also be connected 
with each other: — ab. coalescens ab. nov. (441). — Hindwing black. Mexico (Zacualpan). 
154. Genus: C'lialcamistis Dyar. 
Separated from the preceding genus by the stunted proboscis and smooth frons without an appendage; 
the palpi are the same; thoracal scales much narrower, more hair-like, also with tufts on the pro- and meta¬ 
thorax, and with upturned ends of the shoulder-covers. Abdomen with a basal tuft. But one species: 
C. autoplusia Dyar (441). Forewing purple brown, behind the bronze-scaled median area lighter purple 
with fine brown transverse lines nearing each other at the hind-margin; the maculae are of a bright golden 
bronze colour. Hindwing blackish-brown with a bronze reflection. Mexico (Zacualpan). 
155. Genus: IJfeitmoegenia Grt. 
The species of this American genus being all extremely similar offer great diagnostic difficulties. Closely 
allied to the Chalcopasta, but separated by erect palpi, a rounded frontal appendage without a raised margin and 
central appendage, but with a transverse fillet above it; thorax and abdomen tuftless. 
N. poetica Grt. (45 a). Head and collar yellowish-white, thorax brown; forewing metallic green with 
a broad yellowish-white costal-marginal area, marginal line and fringe, the end of the median vein and its 
branches rising from the lower cell-angle are likewise broadly white. Hindwing feebly brownish. Oregon. 
N. smithi Drc. (45 a) is very near to poetica, the costal-marginal stripe is of a purer white, still broader, 
behind the cell-end the green ground-colour projects somewhat dentiformly, before the margin the white colour 
expands still more almost in a triangular shape, and contains above the uppermost radial branch at the margin 
a small triangle of the green ground-colour; the end of the median vein and its branches together form a large, 
distally three-pronged spot. Hindwing greyish-brown. Mexico (Durango, Guerrero, Tabasco). — sagittalba 
Ottolengui is the northern form from Arizona, and is separated by somewhat reduced white markings. 
N. albavena Ottolengui is a larger, somewhat more slender species; the white costal-marginal stripe 
is upwards more intensely strewn with brownish, almost equally broad as far as the distal margin, the median
