E. asteria Drc. The brown forewings have round lilac-white speckles in basal area, lower half of central asteria. 
area and towards apex. Transverse lines consist of rows of white dots, the outer line being edged inwardly 
by black lunules. There are also rows of white dots subterminally and at margin, in centre of cell there is a 
spot and at close 2 spots ringed with brown. Hindwings brown. Mexico (Tabasco). 
E. deltoidalis Dyar. Forewings dark brown, dusted with red especially below apex. Transverse lines deltoidalis. 
narrow and black with straight shaded black central line. Stigmata with black centres. A dark subterminal 
shade just before the margin. Hindwings grey-brown. Mexico. 
63. Genus: Kill ocastra Btlr. 
There are only 2 american representatives of this almost purely indo-australian Genus. It is similar 
to the preceding but thorax and abdomen are entirely devoid of crests. In all other respects they are identical. 
E. chrysarginea Schs. (52 k). Forewings coppery brown with leaden silvery sheen, especially in discal chrysargi- 
area. Fine double black transverse lines intertilled with golden yellow, the posterior line obsolete in centre 
with a golden brown shade anteriorly. A white dot at apex. Hindwings dark coppery brown. The coppery 
brown abdomen is ringed with white on the second and last segments, whilst the first three segments have 
white spots ventrally. Brazil. 
E. ecphaea Dogn. Forewings grey-brown, paler in disc and at inner margin. A wide white oblique ecphaea. 
band extends from the second third of inner margin to the apex, where it is peppered with brown. Hindwings 
grey-brown. French Guiana. 
64. Genus: Cerathosia 8m. 
This Genus differs considerably, superficially it reminds one of certain Cydosia species with long narrow 
forewings with appendicular cell and normal neuration. Proboscis is absent, palpi porrect, short. The frons 
has a beaker shaped corneous process within a ringed ridge and curved horny plate below. Thorax and ab¬ 
domen are scaled and without crests. The anterior tibiae with short corneous spine outwardly at the extremity. 
C. tricolor Sm. (52 k). Forewings silvery white with numerous black striations, that more or less form tricolor. 
distinct transverse rows. Hindwings pale yellow. Texas, Mexico. — Larva is dark brown or black with 14—20 
warts on each segment, each with 1 or 2 stiff bristles that are expanded at the tip. Both the anterior abdominal 
pairs of feet are missing. 
C. opisthochra Dyar. The classification here is doubtful. Unfortunately both the anterior legs are mis- opisthochra. 
sing in the type. Forewings pale rosy grey with grey-brown shaded band beyond the cell, forming here 2 blunt 
dentations. Hindwings orange-ochre. A small species of only 11 mm wing expanse from Mexico (Tehuacan). 
65. Genus: Monocymia Hamps. 
Proboscis developed, palpi upturned, frons smooth. Vestiture of thorax consists of hairs intermingled 
with scales. On metathorax there is a crest pointing backwards, abdomen without crests. Forewings wide with 
a small appendicular cell and the usual Noctuid neuration, the median radial of hindwings is fully developed 
and arises below the centre of disco-cellular nervure. 
M. harmina Schs. (52 k) has grey-white ground peppered with black and dusted with olive-grey. Both harmina. 
transverse lines are double, intertilled with white. The anterior line is very faint, the posterior one more distinct 
and wide with a coppery reddish shade posteriorly. Stigmata absent. Hindwings coppery dark brown. Brazil 
and Paraguay. 
66. Genus: Cyuioiiia Dyar. 
Differs from the preceding by a large corneous plate with raised edge that covers the entire frons to 
the antennae and in which there is a large round central process. The only species described reminds one of the 
preceding. 
C. harminella Dyar. Forewings pale yellowish grey. Marginal area widely olive-brown with boldly harminella. 
curved inner edge, that is parallel to outer margin. Hindwings dull reddish brown. Mexico (Sinaloa). 
67. Genus: Diastema Guen. 
This Genus embraces some pretty species that resemble the preceding Genus in structure. Palpi are 
somewhat longer and sleeker. Frons has a small rounded protruberance with a corneous plate below. Pro- 
and metathorax and the first segment of abdomen have loose tufty crests. Build generally is sleek. Neuration 
normal with appendicular cell.
