246 NYMPH ALID.E. 



Genus XXXY. CALLIZONA. 



Argynnis God 1 . 

 TlGRIDIA Iliilm. 



Head quite as broad as the thorax, hairy. 



Eyes oval, prominent, smooth. 



MaxillcB slender, considerably longer than the thorax. 



Labial Palpi somewhat porrect, ascending, scaly ; the scales of the first joint and of the back of the 

 second joint long, loose, of the other parts closely appressed. First joint nearly half the length 

 of the second, curved, much broader at the base than at the apex, which is truncate ; second 

 joint slightly curved, subcylindric, rather stouter towards the apex, which is obliquely truncate ; 

 third joint subconic, rounded at the base, the apex somewhat obtuse, scarcely more than one 

 fourth the length of the second joint. 



Antennce nearly as long as the body, slender, terminating in an elongate, rather slender, almost 

 fusiform club, grooved below. 

 Thorax rather slender, elongate oval, clothed, especially behind, with long hairs. 



Anterior Wings trigonate, the apex slightly truncated. Anterior margin curved. Outer margin 

 slightly sinuate beyond the middle, two thirds the length of the anterior. Inner margin 

 emarginate, one fourth longer than the outer. Costal nervure rather stout, terminating about 

 the middle of the anterior margin. Subcostal nervure slender ; its first nervule arising at a short 

 distance from its second, just before the end of the cell ; the third arising about midway between 

 the base and apex of the wing, terminating at the apex ; the fourth about midway between the 

 origin of the third and the outer margin. Upper disco-cellular nervule very short; middle 

 disco-cellular short, but quite double the length of the upper, showing a slight rudiment of the 

 discoidal nervure; lower disco- cellular nearly atrophied, curved inwards, united to the median 

 nervure before the separation of its second and third nervules. Third median nervule curved. 



Posterior Wings obovate. Anterior margin not much rounded, equal in length to the inner. 

 Outer margin shorter than the anterior, sinuate dentate. Precostal nervure simple, straight. 

 Discoidal nervure arising from the second subcostal nervule near to its origin. Cell open. 

 Third median nervule but little curved. 



Anterior Legs of the male slender, clothed with delicate hairs. Femur, tibia, and tarsus all nearly 

 cylindric, the last somewhat pointed at the apex. Tibia shorter than the femur, and about 

 one third longer than the tarsus. Anterior Legs of the female rather slender, scaly. Femur 

 longer than the tibia, smaller towards the apex. Tibia subcylindric, smallest at the base, 

 slightly curved, unarmed. Tarsus shorter than the tibia, cylindric. First joint considerably 

 longer than the rest combined, armed at the apex, as are the two following joints, with a rather
