1182 DIPYLE; ANIMULA. By M. Gaede. 
Th. alcora Barnes. The description corresponds exactly with that of ephemeraeformis. The only differ¬ 
ence is that nothing is said about the colour of the veins. The size (25 mm) is also similar. Described according 
to 1 $ from Arizona. 
Th. pallidovenata Grossbeck resembles a large epherneraef ormis. Antennae brown, yellowish at the tips. 
Body above and beneath dark smoky brown, with a silky gloss. Wings whiter hyaline than in epherneraef or mis, 
the veins also paler. Porewing narrowly dark brown at the costal margin, broader so at the inner margm at 
the base. Hindwing the same at the two margins. $ 34 mm. Described according to a single specimen from 
Florida. The author thinks that the Florida specimens of ephemeraeformis mentioned in literature belong to 
pallidovenata. 
Th. thoracicum Grt. is smaller than epherneraef ormis, wings scantily scaled. Thorax with pale silky hair, 
the other hair brownish black. Forewing with a distinct partition-vein in the cell, which is absent in ephe¬ 
meraeformis. £ 25 mm. Described according to 2 from Cuba. 
Th. microptera Schs. has only 9 veins in the forewing, 3 in the hinclwing. Body black, only the meta- 
thorax and the abdomen at the base brownish ochreous. Wings hyaline. Forewing with brownish ochreous 
veins in the basal area. The hindwing has long black hairs except at the costal margin. <$ 23 mm. Cayenne. 
Described according to a single specimen. 
Th. seitzi sp. n. (169 e) is the smallest species. The veins 2 to 5 of tlie forewing follow each other at 
about equal distances, 6 is absent. 7 and 8 from the upper cell-angle, 10 a little farther back. 11 present. In 
the narrow hindwing a vein extends from the very broad and long cell into the apex, one more each above 
and below it at equal distances to the margin. Above it the cell bends outward almost as far as the costal 
margin and despatches a short vein from the anterior bend to the margin. Body black. Antennae dark brown. 
Forewing hyaline. Brown scales at the inner margin at the base and at the costal margin at the interior half. 
The exterior part at the costal margin and the distal margin are quite narrowly black. Hindwing narrow, the 
terminal third black, the costal margin narrowly black, the inner margin with white hairs. 16 mm. Rio de 
Janeiro, taken by Dr. Seitz. Type in the Senckenberg Museum. 
(Genus: Dipyle Guer .) 
The author assures that Dipyle is allied to the genus Oiketicus. The cocoon is twice as long as it is thick and is open 
on both sides. The shape resembles that of a Venetian gondole. All this shows that the author had a Perophorida at hand. 
The species boucardi Guer. has thus been wrongly ranged in dalla Torre’s Catalogue. 
11. Genus: Aiiiiimla H.-Schaff. 
Antennae of d bipectmated to the tips, in contrast with the likewise hyaline species of Thyridopteryx. 
Veins 8 + 9 of forewing stalked. 5 absent. In the hindwing 4 veins are present, besides vein 8 which anasto¬ 
moses with the cell. Two species are known in the Indo-Australian Region, among them the typical one (her- 
richi), from South America there are 3, and two more from unknown habitats. 
A. dichroa H.-Schaff. (169 d). Antennae blackish. Body densely covered with black hair. Forewing 
hyaline, the veins pale yellow especially at the costal margin. On the hindwing only the cell is hyaline, faint 
black dusting behind it, the inner margin broadly covered with greyish black hair. 28—32 mm. Colombia, 
Venezuela. 1 $ which might belong to it is 26 mm long, 5% mm thick, yellowish brown, with densely arranged 
red-brown spots, a dark brown head and a blackish neck-shield. 
A. limpia Dgn. resembles dichroa (169 d). Antennae black, body with long black hair. Forewing hyaline, 
the costal margin and the veins at the base yellow, then gradually covered with black scales, a few black scales 
also on the whole wing. They are absent in dichroa. The hindwing is black only at the inner margin, thus less 
extensively black than in dichroa. 23—28 mm. Described according to 5 specimens from Ecuador. 
A. basinigra Fldr. (169 d). The figure shows a species which is less similar to dichroa than to dimidiata. 
Body dark brown. Both wings hyaline, somewhat yellowish, the interior two fifths of both wings dark brown 
according to the figure, not black as the name indicates. <$ 18 mm. Brazil. No further specimens seem to have 
been found later on. 
Origin of the two following species unknown. 
A. dimidiata Heyl. The shafts of the short antennae greyish yellow, with dark brown pectinations. 
Body with long gray hair, scarcely projecting beyond the hindwing . Wings hyaline. The forewing widens out¬ 
wardly. The base densely covered with blackish brown scales, the margins narrowly black, the fringe with 
yellowish tips. Hindwing rounded, the base, margin and fringe as in the forewing. 22 mm. — The larval 
bag is 60 mm long, strongest near the base, longitudinally irregularly covered with rests of dry leaves of different 
sizes. Described from the Coll. Oberthur, but apparently not figured. 
A. basalis Heyl. Antennae short, yellow, with long blackish brown pectinations. Body with whitish 
hair. Forewing almost quite hyaline, only the base of all the cells densely covered with blackish hair. Hind
