D1PHYA; DYSODIA. By M. Gaede. 
2. Genus: Dipliya Wr. 
The genus represents the Indian species of Glanycus in the Nearctic Fauna. The only species known 
exhibits a habitus very similar to that of Syntomids or Arctiids; among the latter group it is also quoted in 
older catalogues by the name of Gippius. Palpi short and thick, antennae of the $ tufted. Forewing more ob¬ 
long than in Thyris. The cross-vein of the forewing very feeble. Veins 4 and 5, as well as 7 and 8 very close 
together at the base, 6 far below the upper cell-angle, 9 -+- 10 stalked. In the rounded forewing veins 4 and 5 
are also near together, the cross-vein is absent, 6 and 7 from the upper cell-angle, 8 fused with the anterior 
edge of the cell. Only 1 species known. 
D. sumptuosus Wkr. (173 a). Body and wings black. Thorax with red lines. Abdomen with red lateral sumptuosus. 
spots and anal tuft. Wings somewhat lustrous brownish. Forewing with rows of lemon-coloured spots in the 
basal half. Behind them a few more spots at the costal margin and anal angle. Hindwing with but 3 or 4 spots 
at the margin near the anal angle. 35—40 mm. Mexico. 
3. Genus : Dysodia Clem. 
In the Palaearctic Fauna only a single species penetrates to the confines. In addition there are 3 species 
from the Indo-Australian Region, while 9 species occur in Africa. Hampson, in his monography, enumerates 
only 3 species from America, but we must consider that he did not yet know the species described later by 
Drttce in the Biol. Centr.-Amer. This improbable numerical proportion was greatly changed later on by 
Warren and Dyar, who enumerated about 25 species. We follow the statements of Dyar who in dividing 
the group into such a great number of species is probably going too far, as the separation of igualensis Dyar 
shows. Yet one cannot tell which names of species denote merely forms, without having a number of specimens 
at hand. The species are frequently found described among the generic names of Varnia, Pachythyris and 
Platythyris. Type: oculatana Clem, from America. 
1. Forewing with a whitish hyaline d i s c a 1 spot. 
D. oculatana Clem. (= plena Wkr., fasciata Grt. &• Rob., montana H. Edw., aurea Pagst.) (173 a). The oculaiana. 
ground-colour is yellow, traversed by fine red-brown lines. The transverse bands are red-brown. An indistinct 
band at the base. The interior band is uniformly narrow, rectangularly broken in the middle. The median 
band is broad at the costal margin, with a yellow spot at the costal margin, somewhat broken in the middle 
and then only half as broad to the inner margin. The submarginal band is bent behind the cell, somewhat 
narrower than the interior one. The hyaline spot on the hindwing anvil-shaped. Behind it 2 narrow red-brown 
bands, partly fused. 20 mm. Distributed from the United States to Venezuela, but rare. The larva on the 
leaves of Eupatorium. 
D. vitrina Bsd. differs from oculatana in its violettish red colour. The larva is said to mine in the vitrina. 
branches of Phaseolus, which is out of question in the species of Dysodia and Thyris. The species has never 
been discovered any more. Reported from the United States. 
D. summargo Dyar. Ground-colour coppery brown, somewhat yellowish at the base and costal margin, summargo. 
The dense violettish brown reticular lines are inclined to form rings around a central dot. The bands are 
broad, uniform, rather parallel, dentately edged. The 2 interior bands somewhat bent, the exterior and sub- 
marginal ones almost straight. Margin distinctly notched in both wings. Discal spot of forewing narrow, 
oblique, that of the hindwing large, narrower in the middle. Hindwing darker at the costal margin and anal 
angle, the striation distinctly ring-shaped. 25—30 mm. Mexico. Rather common. 
D. immargo Dyar. Ground-colour also copper brown, only at the costal margin very narrowly yellow, immargo. 
The reticular lines are fine and dense, the light interspaces punctiform. The bands broad, similar to each other, 
the submarginal band terminating into the margin. The hyaline spots as in summargo. Hind wing almost 
uniformly covered with violet reticular lines. The brown ground-colour is only punctiformly preserved. The 
submarginal band is especially distinct on the forewing beneath in summargo , whilst it is absent beneath in 
immargo. The latter is lilac brown beneath, the following granulata is straw-coloured beneath, also without 
the submarginal band. 21 mm. Mexico. Described according to a single specimen. 
D. granulata Neumoegen. Body grey. Forewing greyish brown, with numerous orange red reticular granulata. 
lines forming ellipses, only the distal margin remaining grey. The hyaline spots are irregular. The median 
band close behind it greyish brown, broad at the costal margin, tapering at the inner margin. 5 straw-coloured 
spots at the costal margin, 2 before the band, 2 behind it, one in the middle. Hindwing coloured like the fore- 
wing. The hyaline spot much larger, indented on its interior side. Straw-coloured beneath with brown reti¬ 
cular lines and a brown median band. 23 mm. Described according to 1 $ from Arizona. — igualensis Dyar igualensis. 
has been described as a species likewise according to but one specimen from Guerrero (Mexico). The differ¬ 
ences are the following: ground-colour orange yellow', the body almost the same. The reticular lines form more 
streaks. Forewing with a broader main band enclosing the hyaline spot, the centre of the cell is crossed by a 
transverse streak. The hindwdng is also marked streak-like. 19 mm. Later on, Barnes and Benjamin ascer¬ 
tained from a larger number of specimens from Pima Co. (Arizona) that the species varies from specimens
