Orneodes trachyptera, Meyr. 
(Plate H, figure 11.) 
Orneodes trachyptera, Meyrick, B. J., XVII., 134. 
“ Male and female. 10-13 mm. Head, palpi, antennae, thorax, 
and abdomen dark-fuscous, mixed with whitish ; palpi with second 
joint dilated with rough scales towards apex above and beneath, 
terminal joint thickened with loose scales towards apex anteriorly. 
Forewings with costa roughened with projecting dark fuscous scales, 
except on the white markings ; whitish, densely irrorated with dark 
fuscous, so as to appear dark gray ; costa with six or seven small 
semioval ochreous-white spots, not reaching more than half across 
first segment; other segments crossed by about six series of ochreous- 
white dots, united by outwardly oblique whitish dashes in the cilia 
to form zigzag lines. Hindwings with ground-colour and zigzag 
lines as in fore wings. 
“Six specimens, Puttalam and Maskeliya, in March, May, 
November, and December {Pole, De Mowbray).” 
This blackish little species, easily recognized by its roughened 
costa, is further remarkable in having the maxillary palpi well 
developed and clearly visible beyond the scaling of the head. It 
should probably be separated generically from Orneodes. 
In Ceylon 0. trachyptera usually occurs in the dry jungly districts 
of the low-country, where it sometimes comes into light freely. 
My own specimens are from Wellawaya in November, 1905 {Green), 
from Mankulam and Anuradhapura in November, 1908 {De Mowbray), 
and from Nikaweratiya (between Puttalam and Kurunegala) at 
light on November 11, 1909. (Ormiston). Mr. Meyrick tells me that 
he has it from Eppawela and Rambukkana. 
Outside of Ceylon it is as yet known only from N. Coorg, 3,500 ft. 
(Meyrick Coll.). 
TRisciEDECiA, Hmpsn. 
“ Proboscis fully developed ; [labial] palpi with the second joint 
porrect, about twice length of head and broadly fringed with hair 
below, the third oblique, moderate ; antennae of male ciliated ; 
tibiae with projecting tufts of hair at the spurs. Forewing divided 
into six plumes to rather more than one-tliird length (from within 
two-thirds); the costa with six tufts of scales ; the scaling rough ; 
vein 3 from well before angle of cell; 4-5 from angle ; 6 from below 
upper angle ; 7-8 stalked ; 9, 10, 11 from cell. Hindwing divided 
into seven plumes to half length ; veins 3-4 from angle of cell ; 
5 absent ; 6-7 from upper angle ; 8 free, from base.” 
This genus is remarkable amongst the Orneodidae, not only in 
the six-cleft hindwing, but in possessing well-developed maxillary 
palpi—a feature which is unaccountably omitted from the original 
description reproduced above.
