33. Derunpa, Walk. 
Face roughly haired. Palpi moderate, second joint ascending, densely 
rough-haired beneath, terminal joint slender, clavate, porrected. Antenne 
in male bipectinated (4-5), in female also shortly bipectinated (14). Fore- 
wings with rough scales. Forewings with vein 6 from a point with or out 
of 9, 7 from below angle of areole, 10 from areole or out of 9, anastomosing 
shortly with 9, 11 separate, 12 free. Hindwings normal, 3 and 4 separate. 
Femora densely hairy beneath. 
| This and the two following genera are sometimes mistaken for Noctua ; 
the neuration shows that there is no real connection. The peculiar palpi 
are also noteworthy, being alike in all three genera. D. egregia has vein 6 
of the forewings rising out of 9, 10 also out of 9, and veins 6 and 7 of the 
hindwings extremely closely approximated at base; in D. atronivea these 
points do not occur.

i. (1879), 268, pl. ix., 1.) 4 
Male, RITO mm. RE elongate-triangular, costa almost 
straight, slightly sinuate, hindmargin rounded, crenate; white; costa 
marked with small quadrate black spots, inner margin with irregular 
transverse black marks, hindmargin with elongate semi-oval black spots; a 
black basal spot beneath costa, with a strong posterior projection, and 
a shorter one beneath; a brown black-margined fascia near base, twice 
strongly angulated ; an irregular black fascia from before middle of costa to 
beyond middle of inner margin, interrupted above middle; an irregular 
brown black-margined fascia from middle of costa to anal angle, anterior 
edge with irregular projections above and below middle, posterior edge 
emitting an irregular branch to costa before apex, black margin strong and 
partially broken beneath into disconnected spots. Hindwings moderate, 
hindmargin rounded, crenate; grey, darker posteriorly; a faint darker 
median shade; a fine well-marked irregular dark grey line towards hind- 
margin, with a sharply angulated median projection. 
A most striking and conspicuous species ; the markings vary somewhat 
in detail.
