A. langtoni Coup. (= sacramenti Grt. A- R., hudsonica H. Edw.) (5 a) resembles octomaculata, but 
the white basal spot of the hindwing is absent, only the distal spot being present. Widely distributed in North 
America. Expanse of wings: 34, $ 36 mm. 
A. mariposa Grt. & R. (5 a) on the forewing somewhat resembles maccullochi, but the postmedian 
band is divided into 2 small spots, also on the hindwing, whilst here the basal spot is absent . The shoulder-covers 
are quite black and only the middle tibiae orange. — lunata Stretch by the confluence of the separated small 
spots exhibits crescentiform postmedian bands on both wings, on the hindwing also the basal spot is present. 
Expanse of wings: 38 mm. The species is found in California. — The young larva is amber-coloured, later on 
reddish-white with white dorsal and lateral stripes and between them with very irregular darker markings. 
It lives on Clarkia elegans. 
A. ridings! Grt. (5 a) resembles the preceding form lunata, but on both wings the yellow postmedian 
spots are sharply traversed by the black veins, and it is smaller besides. Expanse of wings: <§ 32, $ 34 mm. 
From the United States and California. 
6. Genus: Alypi©«les Grt. 
Like the preceding genus, but the tibiae are not long-haired, but smoothly scaled like the abdomen. 
The antennae are not so very much thickened. The neuration is the same. Only 3 species are described. 
A. bimaculafa H.-Schdjj. (= trimaculata Bsd.) (5 a) is a larger, black species with 3 yellowish- 
white spots on the forewing and small, bluish silvery scaled stripes between them; in the type the hindwing 
is black, in crescens Wkr. (= grotei Bsd., flavilinguis Grt.) it shows a postcellular spot, and in dugesi Cock. (1 o 
as bimaculata) another one near the proximal margin. From the United States to Mexico. 
A. radians Bsd. (1 c) has instead of the basal spot on the forewing veins striped yellowish-white, 
the discal spot being very small, and from the postmedian band there proceed likewise vein-stripes towards 
the margin. Mexico. 
A. walkeri Drc. {= stuarti Schs.) (1 b) somewhat resembles radians, but it exhibits a very narrow, 
bent postmedian band without vein-stripes behind it. The collar is black, the shoulders exhibit small orange 
hair-spots. Known from Mexico and Guatemala. 
7. Genus: I>areeta H.-Schdjj. 
This genus, better known by the name of Diamuna Walker, contains several rather large, strong, species 
with a somewhat ensiform apex of the forewing. The 3rd joint of the roughly scaled, obliquely rising palpi 
is short; the frons as usually shows a coniform projection; the tibiae are exceedingly long and densely haired. 
In the neuration there is no difference from the other genera. The males which are rather smaller than the 
in the 2 first species exhibit very peculiar sexual distinctions. 
D. falcata Drc. (lb) in the male shows at the costal margin in the middle a membranous, radiantly 
ribbed groove, which is in front bordered by the almost bossily thickened and inverted costal margin; behind 
it the costal margin is concavely excised, somewhat stunted. The forewing is chocolate-brown with double 
darker transverse lines and the veins partly marked silvery blue. Abdomen and hindwing orange-yellow, the 
latter with a broad, dark brown marginal band. The $ is considerably larger. Described from Panama, before 
me from the Coll. Fassl also from Colombia from the Upper Rio Negro. 
D. haenschi Dohrn, described only according to 2 CS, is very much like the preceding, but the hind¬ 
wing is quite dark brown with only a small round orange spot in the middle and a 3 ^ellow proximal margin, 
the anal angle is more produced. Described from West Ecuador. 
D. primulina Drc. (1 c) has yellowish-brown, towards the margin more greyish-brown forewings 
with 2 indistinct antemedian and antemarginal transverse lines. Hindwing orange with a broad brown marginal 
band. Abdomen above blackish-brown, beneath orange. Only the $ is known, described from Mexico. Expanse 
of wings: 42 mm. 
D. severa Cr. (1 c) is a large species, the anterior body and forewings being of a reddish brown, 
with a black abdomen and orange-yellow hindwings margined with black. The forewing shows in the basal 
part of the proximal margin a darker velvety-brown triangular spot and a triple curved, postmedian transverse 
line. Most extensively distributed from Mexico to Surinam, Colombia, Bolivia and the Amazon District. 
D. hesperina H.-Schdjj. (5 a) is very similar, on the forewings lighter, of a more olive tint, and on 
the hindwing the black marginal band broadly borders on the proximal margin, and in the E having hitherto 
not been described it even projects somewhat into the cell. Bolivia (Rio Songo) and Brazil (Sa. Catharina). 
D. proserpina Cr. (lc) is likewise similar, but much darker, the abdomen bluish-black. The forewing 
is much more distinctly marked, in the marginal area of a lighter violettish-grey; on the hindwing the black
