and testaceous in the male and with gi'eyish ferruginous in the female ; the pattern on the 
primaries in both sexes and of the secondaries in the female nearly as above, but much 
darker and brighter in colour : secondaries in the male with scarcely a trace of the central 
line : body below yellow, the posterior half of the venter greyish in the male and bright 
ferruginous in the female. Expanse of wings 56-57 millim.

The genus Omiza is interesting from the fact that the females have pectinated antennae 
just as well developed as in the males.

(ENOCHEOMIID^. 
DECETIA, Walk. 
This genus was described by Walker (Cat. Lep. Het. xx. p. 232) as belonging to the 
family Ennomidse, the type being D. capetusaria, also described by the same author as a 
Drepanodes under the name of D. circulataria ; two other species of Decetia were described 
by him under the names Gynopteryx numicusaria and G. subohscurata, and a fourth as a new 
genus — Auzea, with the specific name j^ufifrontata. 
A short time since Herr Buchecker, of Munich, discovered that the species of the genus 
Sarcinodes (GEnochromiidae) possessed a radial vein in the secondaries — a character which 
proves to be common to the genera of GEuochromiidae, and to them alone (so far as is at 
present known) amongst the Geometrites. 
As the genus Decetia has a radial vein in the secondaries and corresponds in other 
respects with the CEnochromiidse, it has been necessary to remove it to this family.
