There are black dots, particularly on the costal and subcostal veins and there is a black patch near the base and at the end of the cell, as well as an oblique blackish fascia at about one-third to halfway, reduced to a large patch in the fold.
32.
There is a rather dense irroration along the costa, the apex and termen, a spot at one-third under the subcostal vein, another one almost directly beneath in the fold ( somewhat more removed from the base ) and a confluent pair of spots at the end of the cell.
33.
Underside of hindwing : crimson spots more conspicuous, a line of crimson along the posterior portion of the dorsal margin; in most specimens the short subbasal narrow band of white that runs from the costa to the subcostal vein does not coalesce with the white of the discal band where it crosses the cell.
34.
The hindwings are often remarkably small, in the males often with tooth-like projections on the inner-marginal and lower median vein, above them mostly with a deeply concave excision, and between the upper radial and subcostal vein often with an obtuse projection; more rarely the hindwings are quite round.
35.
The forewings are crossed by a broad and somewhat irregular central belt, which is grey-brown towards the costa and enclosing a spot of the ground colour, but dark golden brown below the subcostal vein, crossed by pearl-grey veins with black extremities and transversed internally by a pale sinuous line.
36.
These fossil moths have similarly shaped wings and wing scales, with abundant microtrichia on the wing membrane, comparable with recent Micropterigidae species such as " Sabatinca " and " Micropteryx ", but differences from them by the lack of ocelli and the apparent absence of a branch of the subcostal vein.
37.
The first and second lumbar veins usually join the ascending lumbar vein rather than the inferior vena cava, which then joins the subcostal vein of the same side to form the azygous vein on the right or hemiazygous vein on the left . The third and fourth lumbar veins on the left pass behind the abdominal aorta to reach the inferior vena cava and " all " lie behind the sympathetic trunks.
38.
Hindwing in addition has a white basal streak that extends halfway down the dorsal margin; another shorter white subbasal streak from costa to the subcostal vein coalescent with the white of the discal band in the cell, the streak of ground colour that lies between this subbasal and the discal band jet black, interrupted where it crosses vein 8 by a crimson spot; finally, quadrate black spots near apex of cell and at bases of interspaces 1, 2 and 3, all outwardly margined with crimson.
39.
Forewing yellow, thickly freckled with orange; veins finely ferruginous; lines ferruginous brown, the median thick; all running more or less parallel to each other and to termen; the inner oblique outwards from costa to subcostal vein and again from vein 1 to inner margin where it touches the median; stigmata of the ground colour, with brown rings; the orbicular large, round; both with brown centres; submarginal line formed of disconnected pale lunules edged inwardly with darker; hindwing pale yellow;-" aurantiago"
40.
The forewings have the submedial vein ( vein 1 ) unbranched and in one subfamily forked near the base; the medial vein has three branches, veins 2, 3, and 4; veins 5 and 6 arise from the points of junction of the discocellulars; the subcostal vein and its continuation beyond the apex of cell, vein 7, has never more than four branches, veins 8 11; 8 and 9 always arise from vein 7, 10, and 11 sometimes from vein 7 but more often free, i . e ., given off by the subcostal vein before apex of the cell.
