Tincta. 



Harpe roughly battledore, with corona ; cucullus spinose, 

 with an anal spine ; clasper long and doubly elbowed ;

Harpe roughly battledore, with corona ; cucullus spinose, 

 with an anal spine ; clasper not free ; ampulla elbowed ; 

 sacculus very broad, extending beyond the outer margin 

 and terminating in a bulb, with a pencil of long spines in 

 the centre ; on the upper part of the sacculus is a curious 

 small round hole ; uncus simple ; vesica with band of teeth, 



The Had sen as. In this protean group, we get many 

 and varied forms, peregrina, dentina and glauca, being 

 probably closely connected with the Dianthcecias, of the others 

 with the exception of suasa and thalassina being related 

 the remainder are so different that genitalia fail here to 

 indicate genera, and as in the genus Taniocampa, wing 

 markings and other characteristics must be the guide. I 

 have therefore with the exceptions above-named, taken 

 the Hadanas as they are usually arranged in the lists. The 

 extraordinary difference mvetusta&ud exoleta should be noted 

 as compared with their wing markings and general build, 

 which some writers might put down to a case of mimicry. 



Hadena thalassina. From C. H. Walker. 



Pencils absent. 



Harpe deeply emarginate on the margin ; the costal edge 

 being produced to a sharp curved arm, ending in a tooth ; 

 the clasper is difficult to define, it is divided, the basal part 

 curving to a peak, the upper part extending to a rounded 

 plate ; the ampulla arises from the base of the cucullus and 

 is a peaked plate ; clavus peaked ; uncus simple ; vesica 

 with a short band of teeth, and irregularly shaped small 

 bulbed cornutus.
