EUPSEUDOMORPHA; CYDOSIA. By Dr. M. Draudt. 
347 
Subfamily: Erastrianae. 
This group is not quite uniform and complete, since a small part of the genera ranged here resemble 
the trifid preceding subfamilies, whereas the majority by the decidedly ,,quadrifid“ veins of the hindwing (the 
fully developed middle radial branch rising near the lower cell-angle) is closely allied to the following groups, 
particularly to the gigantic family of the Noctuinae, or as they are now called: ,,Erebinae“ . We find here mostly 
small or very small species with a frequently Geometrid-like habitus recalling that of the Acidaliinae ; another 
type is represented by the great number of Tarache- like genera and species mostly loving the sun and inhabiting 
the steppes; the genuine Tarache are besides the largest representatives, nearly all of which exhibit on the 
white ground-colour spots varying from brown and lead-coloured to blue. The groups with a feeble middle 
radial branch are so closely allied to the Amphipyrinae that they are really very difficult to separate. The 
eyes are smooth, not ciliated, the tibiae without spines, but all the other characters so diverse and heterogeneous 
that not any other common feature is to be mentioned. Only biologically the little insects correspond in the 
larvae — though we know rather very little of the tropical species — exhibiting the four anterior ventral feet 
stunted, so that the walk also in the adult larva becomes Geometrid-like. 
1. Genus: HupseiMlomorgtha Dijar. 
The only species somewhat recalls the smaller forms of the Agaristidae. Head small, proboscis developed, 
the long palpi straightly porrect and below hairy; the frons exhibits a tricuspid horny projection, the most 
central point being the longest; the antennae are also in the $ bipectinate. The thorax is hairy, tuftless, 
the abdomen with a tuft on the first ring. On the fore wing the second and third lowest subcostal branch 
anastomose behind the accessory cell. 
E. brillians Neum. (49 k) is on the forewing black with white and orange-yellow spots on the forewing; brillians. 
the hindwing shows a bronze lustre with traces of an orange discal spot and an orange subterminal band. Only 
known from Texas. 
2. Genus : Cydosia Westw. 
A small number of species allied to the preceding species by the marking and colouring, though the 
wings are much longer and narrower; besides separated by the scaled not hairy thorax, the tuftless abdomen, 
and a large rounded frontal projection with a goblet-shaped central appendage and below it a bent horny plate 
being excised in front. The subcostal branches anastomosing in the preceding species are stalked here, often 
also the uppermost radial branch. The species are partly very similar. 
C. submutata Wkr. (49 1). Purple black, the anterior body white, the patagia with golden yellow spots, submuiata. 
anal apex orange. The forewing shows some white spots, 2 orange golden bands, and between them 2 copper- 
red spots; behind the cell there is no white spot. Hindwing purple black. Hayti. 
C. nobilitella Cr. (= histrio Fabr., jamaicensis Cock., westwoodi Drc .) (49 1) is similar, more bluish- nobiHteUa. 
black, the white spots much larger, all the transverse bands equally coppery orange; the hindwing in the A 
diaphanous white with a narrow black distal margin and apex, in the $ quite black, in and below the cell 
at most somewhat lighter whitish. Abdomen black, in the $ with an orange apex. In nearly all the West Indian 
islands (Jamaica, Cuba, Hayti, Bahamas, Antigua, Tobago, St. Lucia, St. Vincent, Grenadines, Barbados, 
Trinidad), besides known from Mexico, Colombia, Venezuela, Guiana, Brazil. — The larva is velvety black, 
with orange spots, and spines on the 3rd to 5th segments, farther behind finely hairy, the anterior ventral feet 
being absent. It lives on Spigelia anthelmia and pupates in the soil. 
C. mimica Wkr. (46 1) likewise resembles the preceding ones, but it has smaller and more numerous mimica. 
white spots and is easily distinguished by narrow long white marginal streaks. Hindwing of $ quite black. 
From the Amazons. 
C. imitella Stretch (49 1) is a North American species distinguished from mimica by its smaller size imitella. 
and white patagia lacking the golden orange spots. Instead of the white marginal streaks there are 3 white 
spots. Hindwing quite black with a purple blue lustre. Texas. 
C. phaedra Drc. (49 1) differs from imitella in being much larger and in the spot behind the cell-end phaedra. 
being divided into 2 white spots. Mexico.
