t^o submedians, the upper very slender : Mndwing triangularly oval ; costal vein 

 extending to near apes; subcostal two-branclied, first emitted at one-sixth before 

 end of the cell; discocellular bent acutely inward in the middle, emitting a slender 

 discoidal veinlet within the cell from the angle, radial from upper end contiguous to 

 subcostal ; two upper medians from angles at end of the cell, the two lower at equal 

 distances apart, the lower at one-sixth before end of the cell; two submedians and 

 an internal vein. Body small, short, slender ; head very small ; palpi porrect, very- 

 slender, proboscis long ; legs slender ; antennge bipectioated, the shaft thickened 

 towards tip, pectinations short and broad.

Genus CYCLOSIA. 

 Cyclosia, Hubner, Verz. bek. Schmett. p. 177 (1818-25). 



Forewing elongated, triangular, costa very convex, apex pointed ; upper end of 

 the cell extending two-thirds the wing and lower end to three-fourths; first subcostal 

 branch very short, joined to the costal, emitted at one-fourth before end of the cell, 

 second at one-twelfth, third quadrifid, the fourth emitted at one-fifth, the fifth from 

 near end of fourth and extending to below the apex, the sixth (or radial) being thrown 

 off from below the third at about one-fifth beyond the cell ; discocellular very oblique, 

 bent inward near upper end, emitting two short discoidal veinlets within the cell, 

 the upper from angle of discocellular, the lower at halfway below it. both joined 

 together at one-third beyond and extending singly to base of the cell ; two upper 

 medians from contiguous angles at end of the cell, second at one-sixth, first (or 

 lower) at one-third before end of the cell ; two submedians, upper curved : hindwing 

 short, triangularly oval ; cell extending beyond two-thirds the wing, very oblique from 

 first siibcostal branch; costal vein extending to apex; subcostal slender, first branch 

 very short, emitted at one-fifth before end of the cell and joined to costal ; disco- 

 cellular very oblique, radial from its middle, a discoidal veinlet emitted within the 

 cell; two upper medians from wide angles at end of the cell, second at one-fifth, and 

 first (or lower) at two-fifths before end of the cell ; two submedians and an internal 

 vein. Body short; palpi short, porrect, slender ; legs smooth; antennae bipectinated.
