A. gracilis Moschl. (18 h). Body blackish-brown, with a whitish-blue reflection, and a narrow, white gracilis. 
dorsal stripe on the abdomen; the 2 last rings are laterally carmine, so is the anal tuft, which is intermixed 
with black in the <$; in the $ the last ring and the anal tuft are quite red. Wings opalescent hyaline with black 
veins and margins, and a black discoidal spot in the J. Expanse of wings: 34 mm. Surinam; Rio de Janeiro. 
A. dorsilineata Hmps. (18 h). One of the smallest species particularly distinguished by two fine, white, dorsiline- 
dorsal, longitudinal lines running across the thorax and abdomen. Collar and shoulder-covers are bordered 
with white; the whole underside of the abdomen is carmine, above only the last segments, as well as the sides 
of the anal tuft, which is black in the middle. The wings are milky-white diaphanous with narrow black margins. 
Hitherto known only from Jamaica. 
A. paulista spec. nov. (18 h) is one of the smaller species with a black body; anterior side of the palpi paulista. 
and forehead are white; vertex, collar and metathorax of a metallic bluish green lustre. The abdomen 
exhibits above triangular, white dorsal spots, being surrounded by opalescent blue, furthermore white lateral 
spots, and the ventral segments are posteriorly margined by white. The last segments are laterally red-haired, 
the anal tuft is red with a black middle. The hyaline forewings with narrow black margins have a large, black 
discoidal spot; the hindwings are very broadly margined by black. One <L from Sao Pardo from Bang-Haas. 
A. lepida spec. nov. (18 i) ought to form a section of its own, owing to the upper radial rising far below lepida. 
the upper cell-angle. It is allied to the subspecies manca of the following species, but it is still smaller, with 
narrower wings, without a discoidal spot of the forewing, with but narrow black distal margins. The ventral 
side of the abdomen is curled white; above there are white dorsal spots surrounded by a faint blue; the white 
lateral spots are insignificant and coalesce with the white ventral bands. The anal tuft is black in the middle, 
laterally red. One $ from St. Laurent du Maroni (French Guiana); type in the Coll. Draudt. 
A. leucaspis Cr. (18 i) greatly resembles daltiia from which, however, it is immediately distinguishable leucaspis. 
by the absence of the subapical hyaline spot of the hindwing. The under surface of the abdomen is black with 
white sublateral spots. The anal tuft being generally carmine may also be yellow: flava form. nov. (18 i). Not flava. 
rare and distributed from Venezuela through Guiana as far as Brazil. -— In Bolivia there flies a subrace: manca manca. 
subsp. nov. being considerably smaller. Its forehead and anterior half of the collar is white, the abdominal 
spots are also of a plain white, not bordered with blue. The discoidal spot of the forewing and the border 
of the hindwing are broader. 
A. daltiia Bruce (18 i) is well characterized by its size and the hyaline subapical spot in the black daltha. 
marginal band of the hindwing. It differs from the strikingly similar eliza by the two lower radials rising closely 
together and by the antennae not being thickened in the middle, and particularly by the entirely white ventral 
side of the abdomen, only the last segments being black, with white spots; all the hips are entirely white, too, 
and the legs striped white. Amazon (Para); also from French Guiana (St. Laurent du Maroni). 
A. eliza Klages (18 i) is one of the largest and most beautiful species, resembling above daltha so very eliza. 
much that one is obliged to look very closely. Beside the differences of the neuration mentioned there and 
the antennae being thickened in the middle, it may be recognized by the black underside of the abdomen exhibit¬ 
ing lateral and sublateral rows of white spots. Above the first segments are almost entirely metallic blue with 
white dorsal spots, beginning from the 4th ring, the white dorsal spots are placed in blue spots growing smaller 
towards the anal end. •— The species having been described from Venezuela is before me also from Bolivia 
(Rio Songo); the latter form: tenuistriga form. nov. (18 k) has much finer black margins, the discal spot of the tenuistriga. 
hindwing is not coherent with the marginal band. 
A. ocina Druce (18 k) differs from the similar species by the black discal spot of the hindwing being ocina. 
separated from the marginal band. Metathorax and abdomen at the base metallic blue. The abdomen exhibits 
dorsal and lateral rows of white spots, the ventral side is quite white. Anal tuft carmine and black. Expanse 
of wings: 44 mm. Bolivia. 
A. langleyi Klages. The body is black, the forehead laterally white. Spots on the collar and shoulders, langleyi. 
shoulder-covers and thorax are of a golden green; forehips with silvery white spots. Abdomen above of a 
metallic blue lustre, with dorsal and lateral rows of golden green, white-pupilled spots; anal tuft and the last 
segment laterally carmine; on the venter there are 2 rows of white spots. Wings hyaline with black veins and 
margins; base of the forewing black with a golden green spot. Expanse of wings: 30 mm. Venezuela. 
A. platyzona Fldr. (18 k) is quite unlike the other He^Wa-species known and entirely resembles a platyzona. 
Cosmosoma from the stibostictum- group: head and thorax are black, on the forehead and vertex some blue spots, 
the abdomen being orange-yellow, except the first segment and the 3 last ones being black. The hyaline wings 
show broad black margins and discoidal spot. Colombia.
