Median loop of forcMin^^ ending up coterminously with the 

 third median cell; inner low of j^radate cross- veins in fore- 

 wing partiall}^ duplicated C. anomala, n. sp. 



Median loop ending well before the upper distal angle of the 

 third median cell; inner row of gradate cross- veins in fore- 

 wing not duplicated 1.

I Median loop of forewing ending up well beyond the first 

 cross-vein descending from Rs, at nearly half-way between 

 this cross-vein and the upper distal angle of the third 



median cell 3. 



Costal margin of forewing much arched, so that costal area 



)is very wide for most of its length; pterostigma reddish- 

 brown, very large in hindwing C. metastif/ma, n. sp. 



Costal margin less arched, the costal area narrower at base 

 and towards pterostigma; the latter very weakly formed, 



not dark in colour (7. naufaram, n. sp.

\Smaller species; expanse 24-2o mm 5.

 veins in forewing C. araucarvr^ n. sp. 



Forewing as narrow as hindwing; latter with 6 to 7 inner 



gradate cross- veins C. waitei, n. sp. 



Forewing much wider than hindwing; latter with from 3 to 



5 inner gradate cross-veins C. norfolkensis, n. sp.
