- Inferior appendages without inwardly directed spines ( Figs 29 and 50 ); anterior projection of each antenna expanded ( Figs 11, 15 , 25 and 46 )....................................................................................... 4

3(2) Segment X with apices curved inward, rounded, and without lateral spines ( Neboiss 1984, fig. 26); Maxillary palps each having dorsal margin of segment II with large flange (about 1/3rd depth of segment II) ( Fig. 17 )................. C. nemorosa

- Segment X with apices divergent, angular, and with lateral spines ( Neboiss 1984, fig. 22); maxillary palps each having dorsal margin of segment II with small flange (less than 1/3rd depth of segment II) ( Fig. 8 )........................ C. galeata

4(2) Anterior antennal projections larger than posterior antennal projections ( Figs 25 and 27 ); last segment (segment V) of each maxillary palp long ( Fig. 26 )..................................................................... C. cudonis

- Anterior antennal projections smaller than posterior antennal projections ( Figs 11, 12 and 45 ); last segment of each maxillary palp short ( Figs 11, 12, 14, 15 , 46, 47 )..................................................................... 5

5 (4) Hind wings each with fold in posterior margin ( Mosely & Kimmins 1953, fig. 38a); anterior antennal projections each with small rounded branch on lateral surface subapically; 1st segment of each maxillary palp with hook-like appendage on apicomedial margin ( Figs 14, 15 ); abdomen, dorsally with dense setae along midline........................... C. simulans

- Hind wings each with or without fold; anterior antennal projections without small rounded subapical branches; 1st segment of each maxillary palp without hook-like appendage; abdominal terga without dense setae.............................. 6

6(5) Second segment of each maxillary palp with circular brush of large dark setae ( Figs 11, 12 ).................... C. plicata

- Second segment of each maxillary palp without circular brush of large dark setae, instead with sparser whorl of setae ( Figs 46, 47 )...................................................................................... C. equustagna
