A. sanguinea Schaus (19 b). The yellow-white collar, entirely black head and thorax separate this 
species from the similar ones; the first abdominal ring is above yellowish-white, the 5 last ones with carmine 
bands; underneath the 2nd ring exhibits a white spot. The hyaline forewings exhibit a relatively large, black, 
apical spot. Brazil; it is also before me from Paraguay (Puerto Bertoni). 
A. affinis Rothsch. (19 b). By the red-striped shouldercovers and the entirely black head and collar, 
the species is at once discernible from the two preceding, similar species. The base of the hips and a spot below 
the shoulder are white; the first abdominal ring is yellowish-grey, the 5 last ones above with red bands. The 
wings are yellowish hyaline with but very narrow black borders. Brazil (Minas-Geraes). 
A. ceres Druce (19 c). The lustrous metallic blue abdomen spotted white above makes the species 
easily recognizable; the rest of the body is black; anterior side of the palpi, sides of the forehead, neck, 
chest and hips are spotted white. Underneath the two first abdominal rings are white, two middle segments 
and the last ones spotted white. The wings are comparatively broadly bordered with black. Venezuela and 
British Guiana. 
A. placida Druce (19 c) has a black body with metallic blue spots; the strangulated 2nd abdominal 
ring is yellowish-white, on the ventral side broader than above. Ecuador. 
A. minuta Druce (19 c). Body black, with a faint blue lustre; the anterior side of the palpi, sides 
of the forehead, bases of antennae, and spots on the chest and hips are white; the strangulated abdominal ring 
is yellowish; on the underside the 4th and the last segments exhibit white transverse bands. The hyaline forewings 
are yellowish in the disc. Honduras. 
A. eurypon Druce (19 c) has a black body; orange are: a band behind the eyes, and the anal tuft; 
the anterior side of the palpi, forehead, shoulders, sides of the thorax, and hips are spotted white; the first 
4 abdominal rings are laterally yellowish-white; underneath the 3rd and 4th rings show a white band. The 
forewings exhibit an orange-yellow spot at the base of the costal margin. Guatemala and Panama. 
A. augiades Druce (19 c) is easily recognizable by the deep carmine head and thorax; the other part 
of the body is bluish-black, in some places spotted white. From Ecuador, known also from Colombia and Bolivia. 
A. variegata Kaye has a black body. Shoulder-covers striped carmine. The 2nd and 3rd, as well as 
the 3 last abdominal rings exhibit dorsal, double, blue dots, the 5th segment a yellow band. Wings hyaline, 
finely bordered with brown, and with a brown discal streak. Tibiae carmine. Expanse of wings: 32 mm. Parana, 
in April. 
A. laurion Druce (19 c) has a black body; the anterior side of the palpi, throat and hips are white; 
the second and third abdominal rings are laterally and beneath yellowish, the anal tuft, too. A characteristic 
mark of the species is the black distal margin projecting in the shape of a spot between the 2 upper radial veins 
and the lowest subcostal vein, also on the hindwings. The forewings exhibit a small red basal spot, red scales 
being also noticeable at the costal margin between the middle and apex. From Panama. 
A. flavipes Hmps. (19 d) is recognizable by the orange-yellow legs; the body is brownish-black, the 
strangulated abdominal rings are laterally and beneath yellowish. Brazil (Castro in Parana). 
A. magon Schaus (= gyas Druce) (19 cl) differs from flavipes by the black legs with white hips; the 
strangulated abdominal ring is above and beneath yellowish. The yellowish hyaline wings have somewhat 
broader black margins. Brazil (Sa. Catharina). 
A. hadassa Druce (19c) is the most imposing species with a black body; chest, hips, and abdomen 
above and at the sides spotted metallic blue; the venter exhibits on the two first segments white discal spots, 
on the others white double spots, of which the first and fourth are the largest. The yellowish hyaline wings 
with orange-yellow costal and proximal margins exhibit narrow black distal margins. Ecuador. 
A. suapurensis Klages differs from all the other speciesby the posterior tibiae exhibiting rough hairy 
scales; body blackish-brown; anterior body in some parts with yellowish or grey hair; forehips and spots on 
the middle and posterior hips whitish. On the abdomen the strangulated segments are bare, brownish-yellow; 
the next segments bordered with yellow. Wings yellow hyaline, veins and margins finely blackish-brown, in 
some places strewn yellowish; inner-marginal appendage on the hindwing black-haired. Expanse of wings: 
23 to 26 mm. Venezuela. 
70. Genus: Grote. 
Siphon well developed. Palpi long, erect. Antennae in both sexes doubly combed, in the $ long, in 
the $ short. The abdomen exhibits on the last rings lateral hair-tufts; in the the valves exhibit very long 
hair-tufts. The neuration as in Argyroeides, but the middle radial rises on the forewing above the lower cell-angle.
