Sub-Family Firrina'. 47 



Hindwiiigs rounded, generally witli an impressed oval 

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

 tlie reception of hairy patch on inner margin of frontwings ; 

 upper 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- 

 ^vhat near together. 



Body densely clothed with hair; palpi and antenme 

 rather short, the latter somewhat slender with gradually 

 formed club. 



GENUS 25. PTYCHOPTERYX. JFaUeiujrea. 



Type P. Bohemani. Wallengren. 



Frontwings, with brush of long hairs at base of inner 

 margin in males,* first and second sulicostals emitted at 

 some distance before the end of the cell ; upper discoidal 

 nervure springing from cell and not from subcostal nervure 

 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 through the cell and between discoidal and third 

 median branches to outer margin. 



Body hairy ; palpi short, densely hairy beneath ; antennai 

 rather short with bluntly formed club. (Compiled from 

 Wallengren's description.) 



GENUS 26. TERACOLUS. Swainson. 



Type T. Suh/asciata. Swainson. 



Frontwings subtriangular ; first and second subcostals 

 emitted near together and S(jme 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, olilique, angulated ; 

 median branches emitted at about equal distances apart. 



Body clothed with short hairs ; palpi and antennai longer 

 and more slender than in preceding genera, the latter with 

 flattened club. 



* Wallengren says tliat it is at base of hindwings, but I am inclined to 

 tliink this an error, in Callidryas it is on the frontwings.
