48 Mr. Butlei's Bcvi><iov of Genera of 



GENUS 27. I XI AS. Hillmcr. 



Type /. Pyrene. Cramer. 



Frontwings sul)triaiioular ; iieuration almost as in 

 Teracolus but first discoidal nervure emitted beyond end of 

 cell ; upper disco-cellidar half tlie length of lower, botli 

 strongly arched : also in all species except T. jEniiype, Cr., 

 and Marifcmne, the second subcostal is nearer to the end 

 of cell and the upper discoidal branches from the sul)- 

 costal. 



Hindwings rounded; upper disco-cellular one third or one 

 fourth the length of lower, whicli is strongly angulated, 

 both oblique. 



Body covered ^^•ith very short hair ; palpi moderately 

 long, rather hairy ; antennae slender with slightly com- 

 pressed club. 



GENUS 28. HEBOMOIA. Hillmcr. 



Type H. Glcmcvppc. Linnaeus. 



Frontwings elongated; first and second subcostals 

 emitted near together before end of cell ; third and fourth 

 subcostals forming a short fork before apex ; first dis- 

 coidal nervure springing from upper disco-celhdar ; upper 

 disco-cellular rather shorter than lower, angulated and 

 arched ; lower disco-cellular strongly arched. 



Hindwings. Ui^per disco-cellular about half the length 

 of lower and slightly arched, loAver disco-ceUular waved, the 

 two together forming an irregular oblique line : a thickened 

 longitudinal central streak from base to outer margin as in 

 Ptyclwpteryx. 



Body robust, clothed with long straggling hairs ; pali)i 

 short, bristly; antennai moderately long, the club ill- 

 defined, merely a thickening of the shank. 



GENUS 29. HELIOOHEOMA. Butler. 



T}^e H. IdioHm. Butler. 



Frontwings subtriangular ; first subcostal emitted at 

 some distance before end of cell, second at a great distance 

 beyond and near to third and fourth which form a short 

 fork to apex ; first discoidal nervure springing from upper 

 disco-cellular which is about two thirds the length of lower 

 and oblique ; lower disco-cellular oblique, slightly arclied. 



Hindwings. Upper disco-cellular rather more tlian half 

 the length of lower, the two together forming a slightly
