almost as wide as anterior margin of pronotum ; abdomen beneath moderately 



convex i. Genus Cyclochila.

 pronotum about as long as mesonotum including the cruciform elevation, its lateral margins moderately 

 convexly ampliated ; abdomen about as long as space between apex of head and base of cruciform eleva- 

 tion, beneath moderately convex; opercula short, not passing base of abdomen ; tegmina about or nearly 

 three times longer than broad, basal cell scarcely longer than broad, apical areas eight; wings more 

 than half the length of tegmina. apical areas six.
