46 ]\Ir. Butler's Bevisiu/i. of ticncru of 



Frontwings. (Juter margin nearly straight ; cell shorter 

 and stouter; second! )rauch of suhcostal emitted just liefore 

 end of cell ; upper disco-cellular about one third the length 

 of lower, perpendicular and slightly arched ; lower dis- 

 co-cellular strongly arclied; second and third median 

 branches emitted near together. 



Hind wings with more or less caudate projection at end 

 of third median branch ; the subcostal branches and dis- 

 coidal nervure emitted near together ; the lower disco- 

 cellular about four times the length of upper, and sub- 

 angulated. 



Body stout, rather hairy ; palpi ratlier short ; antenme 

 short, slender. 



GENUS 22. KRICOGONIA. Reakirt. 



Type K. Lyside. Godart. 



Frontwings. Cell long as in Goneptcrn.c ; \\i)\)kiv disco- 

 cellular rather shorter than lower, the two together forming 

 an irregular arch. 



Hindwings rounded ; the first and second subcostal 

 branches at some distance apart ; the upper disco-cellular 

 less than half the length of lower, the latter slightly 

 angulated, the two together forming a continuous irregular 

 oblique line. 



Body hairy; palpi moderately long ; antenme slender. 



GENUS 23. MEGONOSTOMA. Reakirt. 



Type M. Ccesonia. 8toll. 



Frontwings generally terminating in a sharp point at 

 apex ; neuration as in Goneptcrijx, excepting that the 

 second subcostal is emitted just before the end of the cell. 



Hindwings rounded ; the costal nervure terminating at 

 the middle of costa ; the upper disco -cellular one third the 

 length of lower, the latter strongly angulated, both oblique. 



Body densely clothed with hair ; palpi moderately long : 

 antenme short, rather slender with gradually formed club. 



GENUS 24. CALLIDRYAS. Boisdiu-al. 



Type 6'. Evhule. Linnaeus. 



Frontwings. Second subcostal emitted just before end of 

 cell ; upper discoidal nervure emitted from subcostal at 

 some distance beyond cell ; upper disco-cellular more than 

 half the length of lower, oblique; lower disco-cellular
