PIICENIX.— DECETIA. 57 



and testaceous in the male and with greyish 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 u(i-")7 millim. 

 Darjiling (Lidderdale, fyc). 



The genus Omiza is interesting from the fact that the females have pectinated antenna' 

 just as well developed as in the males.

DECETIA, Walk. 



This genus was described by Walker (Cat. Lep. Het. xx. p. 232) as belonging to the 

 family Ennomidte, 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. subobscurata, anil a fourth as a new 

 genus — Auzea, with the specific name rufifrontata. 



A short time since Herr Buchecker, of Munich, discovered that the species of the genus 

 Sarcinodes ((Euochromiida;) possessed a radial vein in the secondaries — a character which 

 proves to be common to the genera of CEnochromiidie, 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 (Enochromiida;, it has been necessary to remove it to this family.
