Sitb-Famili/ Pierina'. 47 



Hiiidwings rounded, generally with an impressed oval 

 spot in tlie male, above basal half of subcostal nervure, for 

 the reception of hairy patch on inner margin of frontwings ; 

 upi)er disco- cellular two thirds the length of lower, oblique 

 and slightly curved : lower disco-cellular oblique, angu- 

 lated ; second and third median branches emitted some- 

 what near together. 



Body densely clothed with hair; palpi and antenme 

 rather short, the latter somewhat slender with gradually 

 formed club. 



GENUS 25. PTYCHOPTERYX. WalhngrcR. 



Type P. Bohemani. Wallengren. 



Frontwings, with brush of long hairs at base of inner 

 margin in males,* lii'st and second subcostals emitted at 

 some distance before the end of the cell ; upper discoidal 

 nervure springing from cell and not from subcostal nervui'e 

 as in preceding genera. 



Hindwings. The second subcostal and discoidal nervures 

 springing almost from the same place, so as to reduce upper 

 disco-cellular to a point : a straight and much thickened 

 fold runs throvigh the cell and Ijetween discoidal aiul third 

 median branches to outer margin. 



Body hairy ; palpi short, densely hairy 1 )eneath ; antenme 

 rather short with bluntly formed club. (Compiled from 

 Wallengren's description.) 



GENUS 26. TERACOLUS. Sivaiitson. 



Type T. Siibfasciata. Swainson. 



Frontwings subtriangular ; first and second subcostals 

 emitted near together and some distance before end of cell ; 

 upper discoidal nervure emitted at end of cell and close 

 to subcostal ; upper disco-cellular rather shorter than lower, 

 the two together forming a perpendicular biangulated line ; 

 median branches at nearly equal distances apart. 



Hindwings rounded ; the second subcostal and discoidal 

 nervures emitted together, reducing the upper disco-cellular 

 to a point ; lower disco-cellular long, oblique, angulated ; 

 median branches emitted at about equal distances apart. 



Body clothed with short liairs ; palpi and antemue longer 

 and more slender thaii in preceding genera, the latter witli 

 flattened club. 



* Wallengren .says that it is at liase of hindwings, but 1 am ini'liucd to 

 think this an error, in Callidri/as it is on the i'rontwings.
