50 Mr. Butler's Revision of Genera of 



iijtper discu-cellular alunit half the length of lower and 

 .strongly arched; lower disco-cellular oblique, feebly arched. 



Hindwings. Upper disco-cellular nearly half the length 

 of lower, oblique, feebly arched ; lower disco-cellular less 

 oblique, feebly arched : second and third median l)rauches 

 emitted rather near together. 



Body moderately slender, clothed with short silky hair ; 

 palpi slender, slightly hairy beneath ; antennte short, with 

 flattened club : abdomen of ty})e with tuft of hair below 

 anal valves. 



GKNUS 33. DAPTONOUIIA. Buihr. 



Type D. Flippantlm. Fabricius. 



Frontwings elongated ; first and second subcostals 

 emitted near together before end of cell ; disco-cellulars of 

 nearly equal length, the upper one very oblique, the lower 

 perpendicular. 



Hindwings. i)isc(j-cellulars of nearly ecpial length. 



Body rather slender, clothed with short hairs ; palpi 

 long, hairy beneath ; antennae long, slender, club impressed ; 

 abdomen of male with a pair of strong anal hooks. 



GENUS 34. BELENOIS. Hilbmr. 



Type B. Cahjpso. r)rury. 



Frontwings scarcely elongated ; cell l)roader; lower disco- 

 cellular ol)lique. 



Hindwings rounded ; the cell broader and shorter than 

 in preceding genus : upper disco-cellular shorter, lower 

 less oblique. 



Body more rol»ust, more hairy ; palpi shorter, more 

 hairy ; antenn.e slender with compressed clul:) : abdomen 

 of male witli a pair of very minute anal hooks, sometimes 

 obsolete. 



GENUS 35. PONTIA. Fabricius. 



Type A. Cratmji. Linnteus. 



Frontwings subtriangular or subpyriform ; second sub- 

 costal emitted close to end of cell ; disco-cellulars more or 

 less oblique and varying in relative length ; median 

 branches generally emitted at nearly equal distances from 

 each other. 



Hindwings pyriform; cell more elongate than in preceding 

 genus ; disco-cellulars oblique, the upper nearly equal to 

 lower in type (not in Cocytia) ; the same also applies to the 

 distances between median branches.
